X1 current consumption readings

I have my XPERIA for one week now and I am really impressed though I am kinda worried by its battery autonomy. Truth is that I play with it all the time and I had not the chance to understand how well it will perform on standby. Unfortunately all this week I am charging my unit at least once per day and hearing at reviews that on rigorous testing it lasted at around 2 days, got me worried (maybe I have a faulty unit).
Yesterday I was playing with AE Button Plus, (wonderful app) until I saw one option to bind a key to "Uptime information". In this screen you can find various information about battery status, voltage, when it was fully charged last time, total uptime, uptime forecast, etc.
The most surprising reading was "Current" in mA (milliAmperes). As soon as I saw it I started taking measurements on various occasions.
My results are as follow (all measurements in GSM and not 3G):
Idle with screen off ~50mA (not in standby just the screen turned off)
Idle with screen at lowest brightness ~80-100mA
Idle with screen at full brightness ~175-225mA
WiFi enabled +200mA
GPS enabled +150mA
GPS + WiFi + Full Brightness + CPU processing ~600mA
My device gets quite hot (not uncomfortably though) with WiFi and/or GPS and cpu usage, should I be worried?
Of course I can't possible know if the readings are correct but they seem weird, e.g SonyEricsson claims about 833 hours which is about 1.8mA per hour but in my readings it is nowhere near that. On the other hand 50mA in idling will last only 30 hours which again seems wrong.
In any case even if the measurements are skewed we can have a comparison between XPERIA devices and usage patterns. So what's your Current readings and/or battery autonomy?

Could you possibly do a test with GPRS/3G/HSDPA enabled by themselves? It'll be interesting to see what the measurement is compared to WiFi.

good job u doing here.. it will be good...
my X1 last at most 24hours on moderate usage.. this is bad

Hey Xavier,
I would say that your consumption readings are quite consistent with my X1. I used to have HORRIBLE battery life with it, however after many days of tweaking, I found 2 culprits that were causing my battery life to drop substantially, not letting me even get a full day out of it.
The 2 culprits are: S2U2 and FlexMail
- S2U2 used a fair bit of power, so I enabled SafeMode (set to "1") and that helped out big time. I don't think that SafeMode is a bad thing per say, as the only downside is that the clock will update once you turn the phone back on (i.e. it will 'jump' from the previous time to the current time, takes 2 seconds, no biggie at all)
- FlexMail was enabled to use IMAP IDLE. I'm sure this is the case with any IMAP IDLE e-mail client, as I've heard the same issue amoung iPhone users. It is also important to note that if you use FlexMail, each folder that you enable IDLE for will open and maintain it's OWN connection. Therefore, you should only enable IDLE on the folders that you REALLY need (I only have it on Inbox + Junk Mail). Again, this could be the case with every IMAP IDLE client.
To fix the FlexMail issue, I wrote a MortScript that runs all of the time and checks the current battery level, and whether or not FlexMail is running. If my battery is above 80%, FlexMail will run, however if the battery drops below 70%, the script will kill FlexMail, or not let it start until the battery reaches 80% again.
If anyone is interested, I can most likely release the script for download, as it can be tweaked to support any program/process.
Now my X1 will last about 2 days on standby, and my AEButton + Uptime counter actually shows that the device enters true standby. With FlexMail/S2U2 SafeMode = 0 running, it would never let the device sleep, and my Uptime was the same as when my phone was last soft reset (the counter just above).
If the phone is truly entering Standby (and not just turning off the screen), you'll notice that your Uptime counter is lower than when you last soft reset, proving that the phone really did enter standby.
Hope this info helps you guys out. Took me about 4 days of trial and tribulation to figure this out!

Thanks, at least this is reassuring for me that I don't have a faulty unit. Does your unit get warm to the hand whenever you use WiFi or GPS?
At some point I want to write my own application which will measure voltage and current and make a complete log of usage patterns, something like a battery benchmark utility (ala Rockbox).
I want to add that AE Button Plus Uptime information is a good way to monitor the charging current on the X1, many members report poor charging times with PC USB ports, with this utility you can be sure how much juice your X1 is receiving. The official charger from SE is rated at 750mA which is on par with AEB's measurements (around ~680mA for me). I also used a USB charger rated at 1000mA but I didn't got more current out of it compared to the official charger.

I have X1 from few day's.
Information about current power usage is great think in HTC powered devices (my previous device don't have it). I make little search for more effective use of it, and most usefull app's i found are:

Look most interesning, but crash when my device go sleep, i don't know is it don't like X1, or installed on my X1 as .cab .NET_CF3 - worth to mention, but as last position - UPDATE: after hard reset or on .NET CF3 cooked inside (not instaled as cab) work fine.
There are other tools for read power usage (like HomeScreen++ or mentioned before AE Button Plus), but this on the list monitor battery usage as they main function, and all are free.

You can try out also the program called: battery status. It has an option for powerdrain shown in the today screen. By the way the power consumption of my X1 in mA is similar to yours. See you at myphone.gr

~50mA at idling is strange. here is my readings with the same app:
94mAh with bright screen. Gps, wifi and bluetooth off and with full 3G reception
80mAh half bright screen
47mAh when I wake it up from standby directly after it has entered it
after a while in standby it will go down to ~18mAh
right now my battery is at 50% and the phone was fully charged 2 days and 3hours ago
wifi +200mAh seems to be correct though.

Hmm your readings are low. But lets clarify a bit:
94 mA with full brightness or moderate? (it would help to be specific) If in full brightness then I have quite a difference, maybe it has to do with you using 3G instead.
I get 80mA with lowest brightness.
We agree on ~47mA after standby. I must clarify that I got ~50mA just by turning the backlight, not by going completely on standby because I thought that in standby AEB stops monitoring correctly.
I must test more and see if I can get such a low reading
Thanks for sharing your measurements.

bah sorry for double posting...

Yup you are right indeed, AEB will still get readings and momentarily (just before the backlight skews the measurements) I got a reading of 20mA after standby.

I'm pretty concerned about my X1's battery life, comparing to what I read on forums and blogs about the X1, I have very poor battery life.
My phone lasts hardly a whole day after being charged on the wall charger the whole night, with only moderate use: ~10 mins of talking, 10-15 SMS-es, ~30 mins of wifi internet access, ~10 mins of BT, 20-30 mins of pics/videos and no GPS usage. When I used GPS, my battery went down from 100% to 50% after only 35-40 mins of usage... I'm afraid to even try listening to music cause my phone is probably gonna die extremely fast...
I have SPB Pocket Plus and Pocket Digital Clock installed and running on my today screen. I am also using the Yota phone dialer and contacts. For BT I have the hc4 ObexInbox addon.
In fdcSoft TaskMgr i noticed shell32.exe constantly using 0.8-2% CPU.
162 mA with backlight set to minimum
170 mA with backlight set to 20% (no auto-adjust) - all readings below are in combination with this setting
193 mA with wifi on and connected to AP
175 mA with BT on and not connected to anything
202 mA with BT+wifi
263 mA with GPS in use
90 mA just after waking the device from standby before the reading gets refreshed (this seems extremely high).
I hope someone has an idea why power consumption is so high and battery life so low, because currently my phone shut itself down before 20:00 every day, after disconnecting it from the charger at 06:00, and that is extremely bad (only 14 hours usage).

Does your unit gets warm to the hand if you leave it at idle and do nothing with it after some time? I had the exact same problem once. I would fully charge it just before I sleep and when I woke up it was down to 50%. When I touched it, it was warm and not metal cold like other times.
It was very hard for me to find the culprit, in the end I saw that G-Alarm was causing it (after setting an alarm). When I finally gave up using this program I never experienced the "warm after idle" effect. Other people will comment the same for other programs such as S2U and AEBplus (I haven't used the first and I am using AEBPlus since I bought my XPERIA and haven't seen this effect).
About battery readings, while on idle (power button) you can get readings as low as 18mAh. You have to start the AEBplus uptime screen then push the power button. Wait some minutes and the press the power button again. It should show momentarily a very low current usage.

I decided I'm gonna hard-reset my X1 today and then constantly monitor power consumption while restoring all the applications I am using currently, hoping I'll find the cause of the fast battery drain. If I don't find the cause and I've got a faulty unit I can screw myself cause I live in Croatia where consumer rights and warranty (especially for cell phones) practically don't exist...

Hi Guys,
I also had battery uptime problems.
For me on my X1 I can see the following:
- AE button plus is using a lot of battery on the X1 (I love this application and on my privious Kaiser no problems at all)
- Quick Menue
- Wktask
both have also a negative impact on the battery lifetime.
I am using now X1 Button (from this forum) to assign buttons.
With sk Tools I was changing the boot sequenze in the autostart folder and it was making a difference for me on my X1. At the moment I am making sure that the panelmanager is startin 1st and X1 Button is one of the last things I am starting.
In the beginnin I had only 20-40% battery left at the end of the day
At the moment I have 70-80% left at the end of the day for my avarage usage and of course this is different how much I am using the phone.
From my signature you can see the what rom I am using at the moment.
Maybe this is giving you some thoughts in what directions you have a look.
Best regards,
dingolino

For those that are worried about battery drain and are using AEButton and/or S2U2...
I used to get huge drain problems with both these apps installed with my battery only lasting about 13 hours with light to moderate usage, I uninstalled them and then could use my phone for about 4 days with mod to heavy moderate usage... I re installed AEButton but this time using 2.6.6 (was using 2.6.5 previously) and could still use the phone for about the same length of time similar usage... I then re installed S2U2 but used 1.45 (was previously using 1.37) and the battery still lasts considerably longer than previously, I have noticed no drop in the time it last actually... so if your battery seems to discharge quickly this could be a reason...

After hard-reset I finally get the expected battery life and I'm very happy
The only things I did not install this time are Yota Phone and G-Alarm, do one of those 2 is to blame for the high battery consumption. The phone lasted a day of moderate use and a day of little use (10 mins of talking, 6-7 SMS and 20 mins of wifi internet) and the battery is now at 70% which is great.
So, anyone having battery problems and using Yota and/or G-Alarm, one of the first steps is to remove those, it will probably fix the issue.
Thanks everyone for your help and suggestions

When I had the problem I was using YotaPhone too. It was a new program and I was very suspicious of it. After many tests I saw that this was not to blame. Even to this day I use YotaPhone with no battery problems. For me the culprit seems to be G-Alarm.

Battery Life: desperate for help

Hey,
I know there are a lot of threads about this topic, and I've read a lot of them on my quest to improve my batterylife. I've come from 4-5% usage in sleep down to 2%, but i still think its to much, and could use some assistance.
Like I said, I read a lot of threads discussing this matter but I would like for someone with a little more experience to take a look at the data and tell me what you think.
so here are some screenshots which I dont understand completely.
So what I dont understand is, cpuspy says, 84% of the time my phone was in deep sleep, but the batteryuseage shows something completly different. it shows the phone has been awake almost the whole time.
but if i'm reading BBS correctly there are no mayor wakelocks occurring.
i looked at my battery before i went to bed last night. it was at 59%. exactly 10 hours later when i woke up, it was at 40%. that means it lost almost 2% an hour when i didnt touch the phone once.
so i know stuff like BLN sucks juice, but i havent gotten a notification last night, and i set a schedule for BLN to turn off turing sleeping hours. and it only blinks for 10 minutes after a new notification has arrived and then stops.
i undervolted the CPU a bit (75mV on every speed).
i calibrated the battery (drained completely, removed for 2 minutes, charged to full while phone was off, at 100% removed it again for 2 minutes, put it back in and booted phone)
i wiped the battery stats
turned off a bunch of stuff, like autoupdate on market and other tips i found here on the forum.
wifi sleep policy is set to when screen turns off (btw. sometimes i doenst reconnect after the phone wakes from sleep, anyone got an idea how to fix that?
i'm running galnet miui with the siyahs 2.3 kernel and the KI4 modem.
now the question is, where does that leave me? what am i missing here?

For one day see what your battery life is like when you COMPLETELY disable BLN. Titanium freeze it or uninstall it. Second screenshot, what is that Imapfolders things? It has a high count (I see 1200), maybe try disabling that for a day just to make sure its not an app acting rogue. Another thing, have you disabled samsung bloatware (IM app, social hub, game hub etc).

Most of your wakelocks are radio related. When the phone gets a data request and wakes up to handle it.
I suspect its the K9 push email account that is doing it - anyway to change that?

adding on these questions that i also faced by the thread starter, how does this affect:
AlarmManager
Android System
40s(40s) Count 2336 0.1%
i believe this might be the contributor to the constant phone wakes?

would forwarding my mail to gmail and then getting it pushed from there be better?

from what I've seen on here gmail causes bigger wakelocks. most people recommend using K9. Maybe try a different rom? sounds like a big move however I do know that when running the hyperdroid rom for example most people get amazing battery life. Seen a few nice battery reports with checkrom also

I can confirm battery life on Check Rom coupled with Siyah 2.3 is excellent.
I might be stating the obvious to the OP but have you frozen most of the bloatware in Titanium Backup, ever since i done this battery life has improved substantially.
Also go into Wi-Fi settings > Wi-Fi sleep policy and ensure it is unticked,choose one of the other 2 options
In location and security untick Use GPS Satellites as this will use up lots of battery when it's ticked.
In the Privacy tab untick back up my data as this too will cause battery drainage.
Lots and lots more battery saving ideas, search and you'll find them

well i really like miui so i dont think i'll switch just yet. i'll leave that as a last resort.
i see my mistake here, i should rather be looking at the wakelock count rather than the time correct? K-9 sure as hell has a lot of wakelocks. (counting all wakelocks mentioning K-9, i get more than 8000)
the problem is, my email provider doesnt support push, only imap idle, that must be the reason why its wakeing the phone up so often. although i didnt get any mail last night...
from my understanding push services work a little different, since the app using it doesnt have to be connected the whole time. it gets woken up when the server sends a new message.
i deleted k-9 for now, and i'll see how that reflects on my battery life.
would maybe polling mail every hour be better than using imap idle?
work related i really need a way to get my mail frequently.

have done all of that already, like i said, i've read a lot on the forums (cause i myself hate ppl asking the obvious they could've found out by using search for 2 minutes) but thanks for the tips.
only thing i'm not so sure about is the bloatware. since i dont think miui has a lot of that. but i'll look into that.
thanks for all the help so far.
i'll try to look at wakelock count more than on time.
one really anoying thing is BBS force closes A LOT on miui rom. at least i think its rom related, since i didnt have these problems with the other roms i tested since i got the phone.

Hey Phoboss,
please consider the rom is almost non relevant (except eye candy) to battery drain, the kernel makes the difference! I was on Siyah until three days ago with a consumption of 10% in 8 hours during normal usage of the phone, but then i found this Thread, give it a try (i use extreme edition w/o ans probs) forget about setcpu, if the kernel was compiled right, u dont need it!
Furthermore, why do you replicate so many folders in K9, from my POV the Inbox should be sufficient, but I dont know ur provider, push works fine with GMX, even on a freemail acount
If you want to try more, freeze the Calendar App and choose an alternative, from what I have heard, this helps to get rid of most of alarmmanager wakelogs (to be confirmed).
BTW, im on 75% Battery left right now after 20! hours on Battery with moderate usage (some WIFI, lots of XDA App , some calls and browsing, most on 3G which is always on)

Good Luck!

Does your carrier support Fast Dormancy? Because you can turn that off as well to save a few % batterly life if it's not supported. There's usually a phone/model specific code you can type into the dial pad to switch it on/off (I can't remember off the top of my head what the code is but if you search around you'll find it for the SGS2).

Thanks for the tips, I'll look into that.
Here's a little update from last night. Was sleeping for pretty much exactly 8 hours and lost 8% battery in that time. So I came down from 2% an hour to 1%. Still think that's to much though.
The thing is, in the 40 minutes I'm awake now, I've been using tapatalk and surfed the web and I lost another 5% in that time.
This can't be normal can it?
Battery usage is still showing that the phone has been awake the whole night. As you can see on the screenshot below, between 0:00 and 8:00 I was asleep, screen and WiFi where off the whole time, but the phone is shown as awake. I've attached another bunch of BBS stats, this time sorted by count and not time.
(btw. how do you get BBS to show a graph like on your screenshot karpfenhai?)
And isnt Siyahs kernel considered one of the better ones around? Just curious.
Fast Dormancy is not supported by my operator, BUT I've read that it doesn't matter because my operator propagates that to the phones, and they disable it themselves.
Regarding K-9 checking so many folders, that's because I have them sorted by server side rules. I guess I could limit that to work mails.
Thanks again for the help so far.

I used Siyahs kernel for a while and I loved some of the features but Speedmod has it beat in terms of speed (duh! ) and battery life (I had read that multiple times which made me switch and I noticed a drop in battery consumption when switching to Speedmod).
You can check if FD is off as well but if your carrier doesn't support it may as well switch it off rather than relying on the phone to do it for you (I'd read a fair few posts from my fellow Aussies recommending switching off FD because AFAIK none of our carriers support it and it's a battery drain).
BTW - regarding Wifi sleep policy, I've seen people DEMAND that you completely turn off sleep policy as it's a battery drain (like you, i've been doing lots of battery reading and got mine down to very low consumption thankfully) - try comparing BBS with sleep policy on screen off vs sleep policy off and actually switching wifi off completely overnight.
Also, one thing I found useful was using titanium backup to completely freeze apps I wasn't using rather than just relying on the individual app settings. This also helps because it stops them booting when you start up your phone. Speaking of which, get Startup Manager if you haven't already - just like your home pc: turn off everything you don't need
EDIT: my uni mate wrote a pretty good general guide (for installing custom roms/etc as well as batter life tips) that might help you: http://forum.xda-developers.com/showthread.php?t=1351663

1% an hour is very good pretty much what i get you cant really get much better than than unless you switch off data and sync and most other things, consider yourself lucky you only lost 1% an hour, if your surfing the web for about 40 mins non stop 5% sounds about right too.

Hello again, it seems you are on the right track, go ahead, its getting better
I had the same issue, 2ma consumption for 3-4 hours after unplugging, then it raised to 14-18ma for no reason, my suspicon was the accu wheather widget, but I didnt do any further investigation cuz I switched the kernel and the issue dissappeared, yay
Bbs can provide some more infos even on alarms, check it:
I still have 35% left and I can leave the house w/o getting panic ;-)
Try the kernel I mentioned earlier, you can only win!

BBS is force closing like crazy, cant really use it a lot.
the thing is, i still dont have an idea why my phone is always shown as awake. the one time i could access the graphs within BBS it showed the same behaviour. phone was/is awake the whole time.

As far as I know, this is related to miui, I've seen other users using this rom complaining about fc's..
Search for logcat and do a manual dump to gain the desired data.
Sent from my GT-I9100 using XDA App

I wonder if that constant awake bar is something to do with MIUI - certainly 8% in 8 hours drain isn't constantly awake, it would have drained more.
I route all my email to my Gmail and push that - doesn't seem to give me any battery trouble! I don't know if its a good option for you, or really whether or not its battery efficient, I just really like the Gmail interface.

so i've frozen some apps, wiped dalvik and cache partitions
but unfortunately that didnt really help.
here are some more screenshots (i resetted the data to get a more accurate reading) from the last half hour, during which, as you can see by the screen on time, i havent used the phone.
so do you think its odd that my phone got woken so often during this short time, or am i just to anal about it?

Simple can work well

from what I've seen on here gmail causes bigger wakelocks. most people recommend using K9. Maybe try a different rom? sounds like a big move however I do know that when running the hyperdroid rom for example most people get amazing battery life. Seen a few nice battery reports with checkrom also

Just to back this up im running Hyerdroid just checked been running 20hr 15min and on 83% but dont do any fancy stuff just charge the phone when it needs it

like your battery saving method , but it doesnt help you, if your phone dies during a work day. all the testing i did was basically lab tests, i never really used the phone much during this time. if i start getting calls and writing mails all day, the battery will die, thats why i need to find out whats going on.
i just want to know, if what i'm seeing on the first screenshot in my last post is normal or not. from my understanding its just a little odd that, in the approx. 30 minutes that are displayed, my phone was awake a lot, when the screen wasnt even on (i was under the shower and havent touched the phone ones).

Unusually high battery drain in deep sleep with just GSM on

After freezing some twenty applications with Titanium Backup, I finally got this phone to properly enter deep sleep. Here is a quick demo:
(I'm sorry for the images' quality, it's ScreenFilter in effect)

"lightbox_close": "Close",
"lightbox_next": "Next",

I only have the HD2 to compare, which, either with WM6.5 or Android (CM7 flavour), reported, with its builtin battery chip, 4mA of drain to stay connected to the GSM carrier.
Surely enough, since silly Samsung doesn't like to use decent battery controller chips in their 800USD flagship phones, which any HTC device has, the estimates from Battery Monitor Widget, as, per se, estimates, so I cannot really say the numbers are exact, nor I have a definite idea of how they are calculated.
But still:
And, more in detail:
(yes, I know I could've copy/pasted the txt log in here, but surely a screenshot is nicer to look at )
I shamelessly forgot to take a shot of the Android stock battery usage screen, to which I actually look quite seldom; to my defense though, all these screenshots have been taken one after the other, so refer to the same moment; I had the phone charged, then unplugged it and reset the timer on CPUspy, WiFi stayed on just for a while, then disabled; no GPS, no BT, "GSM Only" selected in mobile networks.
I have found a weird behaviour: the drain is 2mA (according to BMW estimates) for quite a while right after the battery is charged. When you happen to actually "use" the phone for a while, the deep sleep drain instead, as estimated, skyrockets up to 30-40mA, to slowly go down again, but never quite low as the drain on my HD2. In the attached screenshots, it stabilized to 17mA, which is still 4 times the comparison of 4mA for the HTC.
A silly deduction: this must not depend on the kernel nor the ROM, since the deep sleep state has the CPU totally inactive, but is there a "radio firmware" that changes this behaviour?
Most importantly, what are your deep sleep mA readings with Battery Monitor Widget?
On a side note, I briefly connected the Note to my PC via USB to copy over the screencaps, and now after a short USB charge, BMW is reporting 2mA again...

How about sharing what apps you froze?

Without giving a full list (that would be dispersive and especially I would have to write it by hand which is annoying ) I suppose you can start with the obvious, all samsung apps, especially the updaters, and those that have a huge internet background activity (freezing IM+ in my case helped, but that sucks if you use chats a lot... I dont), then pass onto the tricky ones you would never suspect, like Network Location and Google Maps/Google Streets
If it doesn't solve your problem let me know, I will go and compile a list, but keep in mind that at first I just uninstalled system apps from Titanium, so the frozen list will be uncomplete of those uninstalled apps.
Quick update: for just this night, I tried leaving the phone on in airplane mode: 8mA drain just to be in connection-less standby!! That's ridiculous, it drains double with no connection active whatsoever, than what the HD2 needs to keep the GSM network connected. Re-enabled the GSM this morning, went to 17mA, so I suppose the 2mA that I see right after charging are, as suspected, just an artifact of BMW estimates.
This resulted in 4% over 7 hours (4% of a 2500mAh battery) in airplane mode, HD2 under WM drained 3-4% over 8 hours nights with GSM on (on a 1230mAh battery).
This phone does have a ****ty energy management.

I left the note (stock, not rooted) on for about 9 hours this night with 4% battery. This morning it had 1% left. To force it to shut down i opened wifi, read my mails and watched 2 songs on youtube.
All i did for the night was to set it to GSM only mode, close all active apps and clear the RAM from the build in task manager. I haven't experienced samsung apps keeping the phone awake yet.

Hi Bassarnis, and thank you for your report
Your experience may lead to believe it actually drained "just" 3% overnight, yet, with CM7 on my HD2 I had the strangest things happen especially when battery was (reportedly) almost drained.
Android (with its silly battery management) would tell me the phone was at 5%, and I just went on using it until 1%; even doing the nastiest stuff to drain that last 1% it took a notable while before the phone shutted down.
Turns out the battery wasn't really drained, but the phone told me it was, because of the useless, illogic, un-asked-for use of "battery statistics", combined with the fact that this OS thinks a battery is depleted when the dV is still 3600mV-ish (LiIon can stand to be discharged up to 3V with no damage).
In this case your leftover 1% could very well mean, in reality, a 6-7% ;D
I would love to know how much %age your phone drains overnight with GSM, starting from a good charge

I charge my phone while its off. I know the effect you are describing. It could well mean that the battery wasn't properly charged the first few times, leading to the last 1% = 5%.
I don't guarantee that my results are accurate, since bought the Note 48 hours ago. When i bought it, i used it until the battery depleted and then charged it to full while it was off. Now its the 3rd time i charge it and i believe the percentages will be more accurate from now on.
Will try tonight and let you know tommorow

Thank you for your interest in this matter

Here are the results:
As soon as the indicator showed 5% battery left at around 23:00, closed all apps via the build in task manager and cleared the ram. (GPS/WI-FI/Auto-synch/Data = off, network set to GSM only)
Now at 7:00 there is 3% left after 8 hours of sleep time. That is 2% more than the last time. Currently the phone is on it's 4th charge circle using the method posted above (letting the phone shut down by itself, then charging it while off till 100%). I 'll probably do one more circle and then start charging the phone whenever.

after reading this thread was a bit worried so did a test last night,after a full charge from 1 am until 9am with only gsm on it consumed just 1%.
so no complains here on my wife's galaxy tab 10.1 she had the same draining problem,but after disabling the GPS it was solved.

Apparently there is something terribly wrong with either my phone OR my software... are you both on stock ROMs? And which version of firmware?
Thank you!

Ive been getting more than 1% drop over 8hours since my SGS2 days.. so this is nothing new to me.. only my SGS1 could drop 1% every 9.5hrs of idle.

Stock 2.3.6 not rooted here. I believe that battery monitor widget you use keeps your phone awake. Did you check your wake times?

You know, I've thought about it very much, regarding BMW and possible interferences with wakelocks, since it has to update stats every 10 minutes after all... but it's still once in 10 minutes so I don't see how it can weight for so much.
Also, I had battery monitor widget since the phone was still on KJ4 and unrooted, fresh out of the box, without a SIM inside, and with logging every 5 minutes instead of 10.
You can compare the graphs of the battery drain (one day is equivalent to two columns):
Before pimping up the phone, stock KJ4:
After, with ExtraLite rom and Abyss Kernel:
I obviously studied reports from betterbatterystats and nothing big seems to come out from there, apart from three causes for wakelocks that I cannot really pinpoint to anything specific: ActivityManager-Launch and AlarmManager, time-wise, and ActivityManager-Sleep, count-wise.
Out of curiosity, I disabled BWM, to see if anything changes.
But I reckon this is some kind of Schrodinger's cat situation, because I can't know the battery current drain of the phone when BWM is not active, if I don't use BWM
My last resort is to restore the nandroid of KJ4 freshly cf-rooted and see from there
Thank you all again for the interest, and
@EarlZ
1% down overnight is scary, positively speaking. I was content with 3-4% with the HD2 and WM6.5.
I was on the 1% mark overnight (less actually) only with my iPaq 214 But then again, that was not a phone, and its standby was a proper standby. And it had a battery almost like the note's.

Battery troubleshooting (ROM inspecific)

This thread is to discus extremely poor battery life on the Nexus S. When we say extremely poor, we mean averaging <24 hours per charge at idle.
After much research I think it's safe to say that some of us are experiencing extremely poor or contrarily, extremely good battery life and no one seems to have an explanation. I'm hoping this thread will find the answer.
The issue:
Many NS users are experiencing extremely poor battery life regardless of:
Rom installed
Apps installed
Installation method
Battery used
Charging method/battery training
Phone usage
Power configuration/tweaks
When we say "extremely poor" we mean <24 hours at idle, but many users are getting less than 8h/C at idle.
I personally have tested this against several ROMS both GB and ICS. We all see slightly better battery performance with GB ROMS, but never greater than 24h/charge.
My ROM history:
Tested the following ROMS for 4 days each, following the same installation procedure each time.
CM7 (nightly/stable) - ~15h/[email protected]
CM9 - ~13h/[email protected]
CyberGR .v4.5 - ~11h/[email protected]
CyberGR .v5.0 - ~11h/[email protected]
Installation method:
Wipe battery stats
Wipe data/factory reset and wipe cache partition
Flash Dalvik-wiper.zip and wipe Dalvik Cache
Wipe data/factory reset and wipe cache partition again
Format /system/data/cache/boot/sdcard
Flash ROM
Flash Gapps if applicable (CyberGR comes with Gapps installed)
I was running an AUCKF1 Radio for all tests. I did try a few other radio's but did not see any noticeable increase in battery life *edit-flashed XXXKB3 and may have increased my idle time by 6x? still testing*
I've also never personally seen an NS get >24h/C, and I've deployed >40 of them to customers. I've only ever heard of >24h/C here on the forums where it seems quite common.
I've seen reports of users flashing the OTA automatically or manually, and some experience <8h/[email protected] while others see >3d/[email protected] I've also tested the OTA and never saw better than 13h/[email protected]
So, we're trying to find the common denominator between those with good battery performance vs. those with poor performance.
Suspects:
Android OS is almost always reported to be active/awake for at least 50% of the time, even at idle on a brand new clean install. It is always the highest consumer of battery, always keeps the CPU awake.
I propose the following test:
Regardless of your setup, if you are experiencing >2d/[email protected] or with use, please post the following:
Phone model (ie: i9020a, i9020t...)
ROM
Radio version
Installation method
Screenshot of your battery monitor from a full charge over a minimum of 10 hours.
Screenshot of your battery use by application/service (we notice that Android OS seems to be the culprit in most cases of poor performance)
For those getting <1d/[email protected], please do the following and then post the same as above:
Note: This should be done overnight.
Follow the above flash instructions and flash whatever ROM you please.
Reboot to recovery and wipe your battery stats.
Power off your handset and give it a full charge while powered off.
On first reboot, sign into a single Google account but do not restore your apps/backups and disable Google sync.
Do not install any additional applications.
Enable wifi/bt/gps/data/sync and associate to a wireless network
Do not modify any power settings.
Leave your handset to idle overnight for at least 8 hours without touching anything.
In the morning, take a screenshot of your battery use as well as battery use by application/service.
Post Phone model, ROM, Radio version, Carrier, and Screenshots.
I recognize that there is some argument about how fast your battery will re-train itself after wiping battery stats. In my experience the training seems to be optimal after 1 full charge to full discharge cycle, but ultimately I've never seen further training result in >24h/C. Someone please let me know if there's a more accurate way to test this? Maybe we shouldn't be wiping battery stats at all?

I'll get us started.
Sorry, didn't get screenshots after 8 hours because my battery wouldn't last that long.

With light to moderate use, I get 6-10h/C

Hey Ben i just did what you did in the other thread. full charge everything on kill all unneeded services.
I'll admit that i forgot to kill extra services and it plummeted my battery to 92% in about 45min. I had an "oh ****" moment and went and killed the random apps.
Im at 2 hours extra now and lost 3% only, everything still on.
So with that info i'll mention this for me would be considered heavy usage. I'll never have everything on constantly. When I was posting up my results of light usage and getting 3 days - note that i had everything firewalled while on 3G except for my emails and messaging and took a few calls only. everything else was off.
I'm gonna guess that with it all on and actually using the phone i'll hit at most 10 hours, probably not even that.
So that basically puts us about even. I'm curious if you do my light tests...will you be seeing 3 days also ? If yes then we can rule out models basically.

Flashed XXXKB3, factory reset (according to OP instructions), flashed CyberGR .v5 again, signed into one Google account, disabled Google sync+backup, enabled and connected to wifi, bt/gps/everything on, then left my phone overnight. Results.
Looks ****in' Gooood. 1.2%/[email protected] draw.
But then, opened my screen once, played some tunes through BT to my truck, drove around for 13 minutes, went back in the house and left the phone idling again and look at the drop! It's continued to draw like this all day now, just idling. I've done NOTHING but play 13 minutes of music and then back to idle.
What's DOES IT MEAN??!!
So I rebooted my phone and let it idle again without touching anything, and still seeing the wicked battery draw. I dunno wtf to think here, and I can't get the draw back down to 1%/[email protected]
*edit* For the sake of 100% transparency, while the phone was idling at 1%/h overnight, I was far enough away from the wifi AP i'd associtated to, that it MAY have lost signal and given up, so perhaps the wifi hardware finally went to sleep. Does anyone know if wpa_supplicant (or whatever controls wifi in Android) runs is represented by AndroidOS?

Oh. Dur...
I think that may be it. Wifi was probably dis-associated overnight. You can see at the very beginning of the battery recording, there's a sharp dip in charge for about 15 minutes, which corresponds directly to Wifi association, then the draw goes nearly flat (1%/h) for 10.5 hours and the Wifi is not associated.
Testing now... Leaving Wifi on, but dis-associated. See if that nice flat line comes back.

This is a normal night of going out, connecting with friends, a bit of music before. A weekend for when it is most important, these are the results. I forgot to photo the android os but it said it was awake, cpu for 4 hrs.

Regarding the Android OS being highest battery consumer, it might be false alarm:

Although still, that hasn't explained the high drain (<10h/day) you're experiencing.
In your first set of screencaps (the 2h30m one) it seems obvious that the culprit is Mediaserver and Google+? One of the most annoying things about ICS that I found is that after flashing ROMs or kernels, Google-Photos have a tendency to enable sync behind our backs. Someone in my local forum discovered when he logged in G+ in his PC that the pictures in his Nexus S had suddenly shown up in the G+ account even though he never uploaded them there. After he disabled that sync, his battery life improved. As a result, I've grown OCD about checking my sync settings every once in a while. The Google-Photos option doesn't always show right away when we set up a new Google account.

I'm back to 1%/[email protected] with everything but wifi enabled.
All sync settings enabled with no sync delay.
G+/data/gallery sync all enabled for 3 accounts. Receiving about 30 emails in 14.5 hours overnight. This should work out to 111h/[email protected]
The question here for me is that I thought Wifi would use less power than 3G given it's such lower range. I thought that when Wifi was associated that your 3G would automatically disconnect, thus using less power when associated to a Wifi AP than when connected to 3G.
Am I mistaken in this? Is this not the desired operation?
*edit* It may be looking like my draw increased by about 8x as soon as I opened the screen for the first time this morning, and hasn't dropped back down to the 1%/h. Right now it seems to be at about 10%/h again, though I'll report back on this later today.

I'm getting the same...
power drain increases for dunno whatever reason...
right after a reboot it goes ok if I do not touch it... as soon (or five minutes later) as I start playing with it the power drain increases a lot and android OS takes over any other service...
generally to test I wipe the battery stats before booting from recovery...
maybe we should check in logcat what trigger the high android OS usage?

I've checked logcat/dmesg and haven't seen anything super suspect (to my somewhat untrained Android eyes). I have done a tonne of power management scripting/troubleshooting in laptops and other mobile devices but this is really my first serious foray into Android PM, so I may be missing something.

As I said, stock settings from CyberGR .v5. Signed in to all three Google accounts and left sync enabled. Turned off Wifi but left everything else enabled.
Drove around (phone paired to my truck for music) for a few hours today, light/moderate use, and I'm currently sitting at 69% battery remaining, coming up on 24 hours on battery. Realistically, this is probably a little lighter use than normal for me, plus I usually plug in when I'm in the Jeep as I'm running not only music over BT to my Jeep, but also streaming OBDii data from my ECU to Torque (and my screen is usually on full time while driving as I like to keep track of my mileage (troubleshooting fuel efficiency as well ).
So all said, stock settings with CyberGr, Radio XXXKB3, Wifi off, everything else on, and I should easily get 2 full days of light use.
Now that said, I'm still waiting for someone getting 3-5 days to chime in. I still feel something isn't quite right.

Wow. Practically the same as myself but my battery is now around 6-7 hrs before I need a charge. I will have to buy a new battery and see if that is the culprit. Over even just flash CM9 instead, who knows..

I doubt it's a bad battery. You're seeing the same life I was before I flashed the XXXKB3 radio and re-installed the ROM properly. Follow the installation instructions from the OP and see if that solves your problem.

After looking at an earlier shot here I notice my android os stays on most of the time hence my bad battery. How do I get it to sleep?

So does mine, but it is not an accurate reflection of battery drain, per android engineer Dianne Hackborn. Look at the Android OS percentage in my screen shots - it doesn't matter.

For those with excessive battery drain: install Battery Monitor Widget and Better Battery Stats from the market. Those two apps should provide all the data you need to troubleshoot poor performance.
Also, check your signal strength. Weak reception will drain your battery in a hurry.

I have seen so many conflicting articles on this...what is your opinion?

I have seen so many conflicting articles on whether to let a phone battery drain to 0 every once in a while or not, but then I see that you shouldn't ever let your phone drop below 40% as it can help battery life in the long run. What is your opinion? I try not to let my phone drop below 40% and it rarely does. Do you think I should let it drain to 0 to calibrate it every now and then or is that even necessary these days? Also for those of you who get 5 or more hours of on screen time, when you get more than 5 hours do you let the battery drain to 0 or 5% to 10% or generally charge the phone at 40% with getting 5 or more hours on screen time? This phone has generally been a power house for me most of the time. I've had a 1 S7 Edge overheat which Sprint swapped out and it's battery life was obviously deteriorating. I'm just trying to see if I can get 5 or more hours of on screen time, I think at most I probably have gotten 6 to 6 1/2. But I figure that to get more on screen time with that I would have to let the battery drain to 15% or lower. Any input would be very much appreciated! Thank you!

Full cycles are "bad" for li-ion batteries and should be avoided. I came across a very good article about this issue several years ago and I'm sticking to that theory since then.
My usual charges are between 25-95%. (fast charging is always off)
40% is ok, I've read that you shouldn't grow a habit of charging it when it's above 50%, but even that isn't an issue if U don't overdo it.
I do a full 100% - 0% discharge ~once a month or when flashing a new rom (official on this s7 edge).
I don't know if this is the best solution, but my father is using my s5 from 2014 and it still lasts a decent amount of time on every charge.
And I think that 6+ hours SOT is a myth for official roms, even with a disabler app. I mean, if I discharge the phone to 0-5%, i do get 6+ hours of SOT, but on my usual 25% I have between 4 and 5 hours of SOT. It also depends on where U use your phone and how bright the screen is. Also on the apps you use...
So, to sum things up, based on my experience, I would suggest to do a full discharge (till the phone turns off) once a month. It can't hurt. And turn fast charging off, phone charges fast even without it.

I never use fast charge. I accidentally had it turned on during the first charge of this phone. I turned it off as soon as I realized that. I forgot to add that I am not rooted at all. This is day 6 on this phone. My last phone Sprint had swapped a phone that was overheating for a defective phone that had scratches on the camera lens and they sent me a certified pre-owned phone. Which I checked the status of the reconditioning and it was only used from July 4th 2016 to August 24th 2016. . I was at a wedding yesterday and taking pictures for maybe 10 minutes at most but I was out in the sun for about 30 minutes, the phone got up to 43c and 111f so I turned it off after taking pictures and put it in my purse and left it off until I got back into air conditioning and turned it back on after it felt cool again. Did this damage my battery and should I be worried? I am hoping it didn't damage it. How long does it take for a phone to settle in to it's optimal battery of how long it will last till it needs charged? My phone before that would last 16 hours or more. I got it last Thursday then took it to Sprint because the phone getting that hot did worry me and the battery was draining kind of fast but it could be where the battery is settling in too. And they factory reset it I know Android is still building files, but how long should I wait until factory resetting the phone or returning it? When I got the phone it was at 75% which I know is good. Since I got it on Thursday, battery has lasted at most 14 hours but otherwise 8 to 12 hours, do you all think this phone has a bad battery and when should I factory reset if battery life doesn't improve. I have disabled bloatware with PDP and I use Lux Auto Brightness, Gsam Battery Monitor, Wakelock Detector, and my Android settings are all set to the best battery saving settings, I do use Power Saving Mode I also never let my phone get below 40%. I am also trying to figure out if the hot temperatures for at most 30 minutes in the sun damaged my battery or phone or if they gave me a phone with a faulty battery as well. Sprint told me to give it a few days and if the battery doesn't improve to bring it in and they will swap it out. I also forgot to add that I uninstalled greenify to see how it does since Nougat does have the size feature now. I did get 6 hours on screen time Monday night after the factory reset out of 8 to 9 hours on battery but I was downloading apps and setting everything up in settings and disabling bloatware too. I'm guessing I'll need to give it a week to show the optimal battery life so everything is settled in again. But a bit ago it showed I had q8 hours left estimated battery life then just now after turning off power saving it went down to 11 hours estimated battery left. Is that anything to worry about and do you have any tips? I have 1 hour on screen time so far at 78% and at 4:08am it was fully charged but it's now 7:24am. Is this anything to worry about?

Here's screenshots of battery stats and screen on time etc.

I never try to charge my phone when it is still above 40%. I also often do a full cycle, when it turns of automatically from itself, I power it on again, it goes out again and then I charge it.
But since Android 7.0, I don't reach 20 hours anymore. my SOT is never above 4 hours, I never be able to reach it. My screen is most of the time on the lowest except now with sunny days on 75 or 85% or brightness.
My Note 3 had a way better battery then this S7 Edge and I did the same "style" of charging.

I never use fast charge. I accidentally had it turned on during the first charge of this phone. I turned it off as soon as I realized that. I forgot to add that I am not rooted at all. This is day 6 on this phone. My last phone Sprint had swapped a phone that was overheating for a defective phone that had scratches on the camera lens and they sent me a certified pre-owned phone. Which I checked the status of the reconditioning and it was only used from July 4th 2016 to August 24th 2016. . I was at a wedding yesterday and taking pictures for maybe 10 minutes at most but I was out in the sun for about 30 minutes, the phone got up to 43c and 111f so I turned it off after taking pictures and put it in my purse and left it off until I got back into air conditioning and turned it back on after it felt cool again. Did this damage my battery and should I be worried? I am hoping it didn't damage it. How long does it take for a phone to settle in to it's optimal battery of how long it will last till it needs charged? My phone before that would last 16 hours or more. I got it last Thursday then took it to Sprint because the phone getting that hot did worry me and the battery was draining kind of fast but it could be where the battery is settling in too. And they factory reset it I know Android is still building files, but how long should I wait until factory resetting the phone or returning it?.........

First of all, don't worry about the heat. Taking pics + sunny day means that it will get hot no matter what. And no, that didn't damage your battery. That was the chipset that was getting hot, not the battery.
Exposing the battery to heat for a long time could affect it's life, but this was ok.
Which apps did you disable? What kind of disabler are you using?
Advice: don't use battery monitoring apps like those that you mentioned, delete everything that's monitoring things and just let the phone settle.
Also, disable all the toggles in notification bar that you don't use. NFC, sync and so on... In settings menu under advanced features, turn everything that you don't use off. Under connection settings, put the location to battery saving and also turn off everything that is unneeded, go to more connection settings and disable everything there.
I don't know if you use samsung cloud, but I disabled everything in there.

I use Package Disabler Pro. I'll screen shot then post them in a bit. I also switched from Chrome to Samsung Internet as I have seen a lot of reports that Chrome can be a battery hog. Since 4:48am my battery has dropped from 78 to 68 and it's 5:26am. I have used FB, Instagram, Gmail, and Samsung Internet. The only battery monitoring app I use is Gsam. I like to keep track of temperature, wakelocks, held awake and my phone signal. I live in a good signal area. The phone did get to 39c just a little bit ago too. I have disabled all you suggested. Settings, Notifications, locations, no sync, location etc. Everything that isn't needed is turned off.

It's now 6:51am and it's at 54% and 3h 8m on battery and on screen time is only 1h 40m...
I have wiped cache twice due to disabling and clearing Chrome data and cache and something on a website on XDA crashing twice on Samsung browser and restarted the phone twice since charged at 100 at 1:23am. It shows 4h 10 m on battery and 2 h 24 for on screen time, it shouldn't be doing this. That's only maybe 7h on this charge. :/ I'll charge it and see how it does today.

Here it is.

Well of course you try to keep you're phone off the charger constantly and should always let it cycle every once in while but the one HUGE downfall for Android 7.0 for them s7 is the standby drain i found bc alot of the system apps don't let phone go to sleep or "doze" so one app I found that really helps is apps ops permission manager all you need to is just go into the app "prevent the phone from sleeping" option and hit ignore on most apps if you don't mind rooting your phone bc I my phone just went overnight while i slept without charging it and manager to stay at 100%

Does that app require root?

So what is your style of charging? What is a good percentage to charge at? I have never let it get below 40. It's rare that I do. I know it getting below 15% isn't good for the phone at all.

yes the app ops requires root

I don't know if I use the correct method, I read a lot about it too and everyone says something different.
I just use it fully, when it goes below 10% , it goes below 10 % and cause I charge it overnight, with a low mah charger (takes maybe about 4 hours to charge), it is always at 100% for a few hours but that does not seem to affect to battery. I notice when using the quick charger, the battery drains a lot faster as well while using a slow charger, it keeps its juice longer in the phone...
but sometimes I notice that the phone gets quite hot and now with the screen brighter then during wintertimes, it really goes fast.
When I'm reading on XDA that a lot of people have +4 hours of SOT with stock unrooted firmware, I don't understand how that is possible.
Maybe I'll do a factory reset or will root it so I can better check what is really draining the battery.
Since Nougat firnware, GSAM Batterij monitor can no longer specify what the culprit is that drains the battery. it just combines the apps.

Actually Gsam can, you can enable more stats by using ADB Click enable more stats and it will walk you through and it won't say combined CPU usage anymore it will actually show the apps.
Here's the code:
adb devices
List of devices attached
* daemon not running. starting it now at tcp:5037 *
* daemon started successfully *
ad04c0b9 device
adb shell pm grant com.gsamlabs.bbm android.permission.BATTERY_STATS

I had downloaded AdBlock Fast and then lost data connection, I tried turning data on and off, and then tried ##72786# then lost ability to call or text so I had to do a factory data reset and go through hands free activation Sprint swapped my phone out for a new S7 Edge earlier today Sprint Total Equipment Protection today. It had been overheating a lot.
