A few days back I complete a full charge of my galaxy and I went to bed. In the morning I checked my phone to see if I had new messages and to my surprise, over night, my battery had lost only 4 percent of its charge for a total of 7 hours and a half after I unplugged it. This is the first time I see such little battery usage overnight since I've upgraded to gingerbread. At first I thought it was something random because I haven't installed, uninstalled or changed, in general,anything. But after awhile I remembered that in fact I had change something. The change I have made was not on the phone. I've removed the duplicates using the new web interface of gmail and then let the changes synced-downloaded to my phone. I Have automatic sync, radio data and wifi always on and also I have an exchange account configured and i'm using viber and facebook messenger app (all these apps are configured to use push functionality).

Notice how when your screen is off, your phone is still awake? That means it's not idling at a low CPU frequency, but instead performing battery-draining tasks—essentially, something is keeping it awake. Something is causing 'wakelocks'. That should give you enough to google for a solution.
Fix that and you'll see a dramatic improvement in battery life, like easily doubling that.
have you noticed the uptime maybe???
have you noticed the wake time has no inpact on usage ???
anyways you want to improve 7 DAYS 13 HOURS DRAMATICLY
are you sure you know what youre talking about =)

Jesus, I thought that said 7h. 7 days? I'm inclined to believe that's photoshopped. I seriously doubt an i9000 can acheive 7 days while the phone is awake for over 50% of the that time. I can't see it—at all.
The majority of users with appreciable battery life achieve 1% an hour loss with the screen off, phone sleeping. That would bring you to 4 days with zero usage, and certainly not much (if any) awake time. If you were to assume 50+% awake time, you are not going to hit 4 days—let alone 7.
Tell me your secret, otherwise I ain't buying.
EDIT: Well, the 'awake' and 'screen on' sections seem to align properly with the graph. Hmm... so what's the secret? A 5000mAh battery?
that 'wake' indication does not mean that phone aint in deep sleep (under 100Mhz state)
probably indicates that some tasks are running in the background not waking up the phone
i do not use percents when i talk about juice used by phone
look for mA in battery monitor widget and i see 2-5 mA every minute
look that screen is off for few days straight, probably all time on 3g with any sync deactivated
wifi the biggest drainer also off, same must be with bt,gps and rotation
phone was probably used for few phonecalls and smses with cpu downscalled to 100Mhz locked
this ways you can easy go for days

I thought the entire purpose of the awake thing was, you know, to have a purpose. So when the battery history section shows the phone as being awake, it doesn't necessarily mean it's awake? Great. That simplifies things.
I can't lock my phone on 100mhz, it instantly freezes. If I could, I suppose I could see the 7 day mark. Either way, I'm shocked that the awake thing reads about 50%. From owning this device, I definitely thought it only showed awake when it was awake. I have never, ever seen otherwise on my device. For example, my phone is set to enable 3G/Wifi and check emails every 15 minutes while the screen is off. On my battery screen this morning, it showed my phone waking up every 15 minutes for the entire night—and it never showed it waking up at any other time.
But what do I know, I use % to talk about battery.
i realy do not know what does that "wake" mean what state is that describing
i am on stock kernel, with no-frills cpu i can change the mhz to whatever value i like. for example i use 3g with phone locked on 100Mhz and i can listen an aac stream for a whole day (still 3g means no incomming calls when i use it), changing to umts means more battery usage but i can recive calls
with 100Mhz phone is very laggy, with 200Mhz gives a bit lag and much less battery is used - and if incomming call i can take it wo problem
lecing umts and 1Ghz would mean few hours drainage, with 3g and 100Mhz i can listen to stream for hours
if you would look more on mA mV mAh data you would understand why those % means nothing. especialy that sometimes bat stats gets messud up completley, with a result of like 50% drop after reboot so after that % goes up untill proper level
as for sync, i got autosync with data connection always on still i can get few % during night

I'm impressed! I've set my clock to 400 Mhz before, and the phone was surpsingly usable (little lag here and there), but 100 and 200? That's remarkable. Anytime I set my max cpu frequency to 100 Mhz the phone instantly freezes; if it doesn't, it will when I shut the screen off.
Do you actually use your phone at these clock speeds? You said you can stream music for hours. Do you? That is truly impressive. I'll have to try this.
And yes, I know a decent amount about batteries. When I got my first Android phone I was obsessed with improving my battery life. I just feel that percentages are easier to understand for people, so I use them more often. Clearly I have a thing or two to learn from you though, haha.
at 100Mhz phone can vlearly perform one task =)
i was suprised that the aac stream was playing but it was
surley thats not freq for everyday use ;]

Certainly, haha. That's impressive. I'll have to remember to underclock my device when playing music for hours. That would probably help the battery quite a bit. Thanks for the ideas!
EDIT: 800 thanks, congrats!
Ok. Have a nice day all. Some of the things I read here doesn't make sense. For example: underclocking the phone as low as 100 mhz, a single task, which in fact uses the cpu and not some other hardware component, will take x10 the time to complete using 100 percent of the cpu. The power usage will sky rocket because the reduction of the operational voltage of the cpu while underclocking it is not even 30 percent of the voltage on 1 Ghz.
The reason I created this topic is to find out if someone had observed such a behavior and, if possible, to help folks with power usage problems. Because they've passed a few days since, I can tell you from the battery usage graph that my phone while idling it wakes up less frequently and I can see these periods lasts not so much time as before... I believe this improvement in power usage is relevant to the way google related services wake up the phone following the automatic sync 'schedule' in order to sync the phone with the google web

you are wrong
power consumption (P) of any processor
is proportional (factor K) to voltage squared (u^2)
multiplied by clock frequency (f)
so: P = K * u^2 * f
for example:
1GHz: u = 1250mV
100MHz: u = 900mV == 1250mV * 0.72
100MHz : f=10^8 ; P_100M = K * (u*0.72)^2 * 10^8
P= K*u^2*0.518*10^8
1GHz: f = 10^9; P_1G= = K * (u)^2 * 10^9
P= K*u^2*10^9
task duration with 100MHz clock is 10 times longer than with 1GHz clock
and Energy (Work W) = Power * time
W_100M = P_100M * t * 10 = t*K*u^2* 0.518*10^9
W_1G = P_1G * t = t*K*u^2* 1*10^9
what do you see ?
energy reduction W_100M / W_1G = 0.518
it's almost half the energy than using 1GHz when reducing voltage by 28%

You are absolutely right. I have not done my homework. Thanks for giving me the chance to actually learn something

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:

PowerGuard v1.2 - homepage
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.
[Edit:] I've changed the title to reflect 110 hours. The original title and body of post reflected 100 hours, but since then I've added two more screenshots at the end of this post to show 110 hours (4 days 14 hours), and I added a (absolutely horrible) video to show that I'm running a standard battery (not an extended battery). NOTE: When I say the video is horrible, I mean it came out sideways, and is barely readable, and is a ridiculous 29MB in size. But the two added screenshots back up the readings and statements in the video. What follows below is my original post.[/edit]
Hey all, this is probably not any real record around here, but I wanted everyone to know I've just passed the 100 hour mark, running 100% uptime since the last battery charge!

Notably, for at lease one-third of the total time, the phone was in an area of poor (or no) signal strength.
For this test, I had wi-fi, mobile internet and GPS all disabled...the only active radio enabled was the telephone voice radio, which was always enabled. I could (and did) recieve calls during the entire time (though I kept the conversations very short).
Here's how I've got my phone set up:
nfinitefx45's stock 2.1 ROM and Darch's Infinitefx_vUV_710 kernel, without freemem tweak (it's not the new vUV2 kernel).
SetCPU, set to 614mhz max and 19mhz min (245 max & 19 min sleep mode), with additional fine-tuning.
AutoKiller, with values I set individually for the different fields (didn't use any of the pre-set options...my settings are probably pretty close to "Agressive", except for the Content Provider value).
I use Advanced Task Killer to kill any apps that I'm no longer using, and I always have. But I've got it set to ignore SetCPU (because I've got a screen-off profile defined and enabled), and also set up to ignore AutoKiller (but I'm not sure if that's really necessary).
Notice the amount of time the phone spends at the different cpu speeds:
Because of the way I've got SetCPU set up, even though I have max speed set to 614mhz my phone rarely runs at that speed...the Powersave bias is set to 125, so most of the time that I'm demanding any real-time performance from my phone, it's actually only running at 537mhz. Likewise, even though screen-off max speed is 245mhz, most of the actual activity in that mode is at 122mhz or 160mhz, again due to the the Powersave bias setting of 125.
Also note that a great deal of time is spent at 19mhz, during both screen off and screen on states. Even so, I experience no noticeable lag, because the phone immediately jumps up to a faster speed as soon as any need arises (such as swiping between screens).
In case you're wondering why some cpu time is showing at 710mhz even though I have the max speed set to 614mhz, remember that I'm running the 710mhz kernel, so while the phone is booting it's running at 710mhz.
I must admit to being miserly in the use of my phone during this test, even though I burned a couple of percent battery downloading the ShootMe screenshot app last night (just so I could provide these pics). And I used EStrongs File Explorer to send the screenshots to my computer over the wi-fi so I wouldn't have to plug in the USB cable.
One more thing...I'm not done yet! I'm going to get another screenshot after my Saturday afternoon nap...hopefully I can get 110 hours out of a single charge.
Cheers!
[Edit:] Here are the two added screenshots that show 110 hours (4 days 14 hours), and the horrible video I shot to back up the fact that I'm using a standard battery.[/edit]
Thats crazy!

That's a lot of time on one charge. But as you said, not using it much. I think the 2+ hours of awake time is telling.

The point of my post was to show how I've set up my phone to conserve battery when the phone isn't actually busy doing something.
Many forum members, in many different threads, have stated that they burn through battery at a rather disappointing rate even when they're trying to conserve juice. Darch went to the trouble of building up a batch of UV kernels to alleviate as much of that problem as he could (thanks Darch!). In large part, my post was basically explaining how I've taken advantage of that kernel, and nfinity's ROM (thanks to you too, nfinityfx45!), and careful tailoring of system and app settings to set my phone up so that battery drain during periods of inactivity is minimized.
Taken as a whole, the results indicate that my average battery drain is less than 1% per hour. In light of the fact that one third of that total time was spent trying to stay connected to a poor signal, I'm quite confident in stating that during times of good signal my bettery drain is significantly less than 1% per hour.
How many people can say they're realizing that kind of battery conservation with their Hero on an everyday basis? I've gone to the trouble of determining what works and what doesn't in terms of conserving battery, and reported on the setup and the results. That's all.
Another point that could probably be taken from the data is that, all other things being equal, I would probably get better battery life doing the same everyday stuff with my phone than the regular Joe who hasn't taken similar measures to minimize unnecessary battery drain on his device.
The bragging was just icing on the cake!
Edit: So sorry, I meant to also thank urushiol for the UV kernel!
This is pretty sick! Are you also using an extended battery?
i thought that auto killer is bad if you use an OC kernel?
thats hella right though
i've been waitin for someone to post somethin like this so i can maybe get 24 hours with moderate usage

Nope, I'm using the original battery.
The phone just now beeped at me, and the warning screen says I have no more than 9% battery remaining. In two more hours I'll have 110 hours on the battery. At that time I'll use my wife's Hero to take a video of my phone's battery usage screen, and then I'll pull the battery cover off of my phone in the video so you can see I'm running a stock battery...it says "HTC Innovations" on it.
I'll post the video after that.

AutoKiller is only bad if you're using one of the kernels with the built-in free mem tweaks.
That's why I'm not using a kernel with free mem tweaks...that way I'm free to use AutoKiller and set it up like I want. And I want a custom setup, not one of the preset offerings that comes with the app. I want to use agressive values for most of the settings, but I want to set the kill value for Content Provider to a low number, because if I use the preset value for Content Provider in the Agressive setting, it will kill the GPS antenna input to my tracking app when I'm on my mountain bike, because the phone's in my jersey pocket with the screen turned off...in such a situation AutoKiller presumes the content provider to be a background app and shuts it down if the kill value is set to anything but low...sheesh!
Okay, I've edited my original post to include a HORRIBLE video showing the standard battery being used, and I added two more screenshots showing 110 nonstop hours on a single charge.
So I'm going to finally put this project behind me now, and get back to the truly enjoyable business of actually using my phone again!
And a HUGE thanks to all the devs who've made it possible to get such incredible performance out of our phones!
If anyone cares to know why I decided to use any of the settings that I did, just ask and I'll be glad to talk to you about it.
Cheers, and a good night to all!
wow thanks for the info on autokiller
i can actually use it again! whoo!
Hi everyone,
I have had my Galaxy S for a month now, I have been very unhappy with my battery life, so I thought, I gotta to fix without compromising perfomance.
I found it!
My battery life during this 1 month period was utter crap, battery used drained from 100% in about 10-12 hours on average.
At the time I was running the latest FWs (I kept updating as the FWs came out) with Mimocans EXT4 fix.
I was with lowest brightness setting, running on 2G without any screen animations.
So heres the fix:
Install SetCPU 2.02, make sure to apply on boot, make the minimum speed 100mhz and the top 800mhz.
This ensures the phone doesn't ever go to 1ghz but that the performance is never compromised (even when playing games, videos, apps).
Because I have the Mimocans fix, everything is smooth and battery life goes down very slowly!
Heres the stats of my battery right now:
Battery Level 70%
21h 40m 25s secs since unplugged
Display 37%
Phone Idle 27%
Cell standby 21%
Voice calls 7%
Android System 4%
Internet 2%
Android OS 2%
You can give this guide a go, sorry if it doesn't work, just trying to help.
Regards,
Azazin!

Please update with display time, phone idle time, standby time and voice call time. Without it these are a bit useless, these don't seem far from my stats when I use the display for +/- 1 hour.

I have the percentages up in the OP.
This guide isn't just for turning crap battery life to good, it's also for people to extend their battery life if they already have a decent one.
Following the underclock to 800mhz my phone can last this long, compared to before when it used to last 10-12 hours with same usage!

The percentages stand out, thanks, I saw them. Again, they are a bit meaningless without the time used. If you don't use your phone for 24 hours you should lose maybe 5% with sync off.
So, please, click on "display" and report the time that the display has been on, repeat for the other usage categories, other people will ask for this same information. I don't know if you didn't know how to do that or if you are witholding the information, hopefully it's just the former. I understand that, perhaps, you are doubling your battery life, but depending on the way we use our phones, relative to the way you use your phone we can see better or worse results. Doing this will allow us to know how much you use your phone and for what purpose, so we can make personal judgments about its merits to our usage.
TIA
This may fix the issue but it's merely a patch to cover up the wound. From my experiments I've found that in most cases the problems are related to the phone never entering sleep-mode. If you have bad battery life, please do the following:
0. Make sure you phone has been running on battery power for a while, usually a day with only 20% battery left is a good place.
1. Type *#*#4636#*#*
2. Go to Battery History
3. Other usage and "Since last unplugged"
4. Check the "Running" bar. Generally, if this is over 60% something is wrong.
5. Go to partial wake
6. Check if there's some application (e.g. Facebook) that has a high partial wake percentage. This is bad. System should be on top on most systems.
So, do you have the signs of something being wrong? Fear not! Usually this is due to a program or service misbehaving. I had bismal battery life (about 15 hours, just check the other thread for several of my posts), and then I uninstalled "Weather from Yr". I also let my phone discharge completely, then charge TURNED OFF over night. I then disabled auto brightness and "power saving" in the display. Yes, I disabled the power saving feature, and my battery life went sky high. Now I have about 2 days of moderate use (1h 30 min on) and about 1 day with heavy use. Letting any application run while the screen is off using partial wake KILLS my battery.
Unfortunatley, I didn't follow proper scientific approach when conducting my experiments, so I can't say which of the three things (uninstall weather from yr, complete discharge/charge cycle or turning off power saving) that did it for me, but it's worth a shot if you haven't rooted your phone. Post back with results.

Hi,
Oh okay lol, no problem.
Display: 1h 22m 8s.
Phone idle: 20h 51m 22s
Cell standby: 12h 12m 52s
It doesn't look like I have used it much but during the time the display has been on, I have either been:
Playing games,
Texting,
Twitter,
Or Internet.
It doesn't look like much, but I recommend you try this and post results before and after

2 things:
1) the phone number thing is pretty cool, in the past I've used "Spare Parts" for identical and a bit more information. I encourage people to use one or the other.
2) You can still fix the unscientific nature of your experiment by a factor of 1/3. You can turn power saving back on, and I'll try it. Also, I'll assume that 1 charge wouldn't make a world of difference, so I think that could've added a few minutes to your phone life (more than charging with the phone on) but maybe someone with actual technical knowledge can chime in.
As for any program running in the background, I had a similar situation where I was going from losing about 30% in a day, similar to the OP, while using the phone, and hence the display, for about an hour at work. I also, always preferred to leave the phone off the charger overnight, so I'd have been unplugged for 16+ hours. One day I allowed 3 things to run to check both battery and 3G usage (I have 500mb per month until I decide to change my plan, probably waiting for the new deal thats been announced for unlimited data for an extra 10 bucks sometime this month). So, I ran:
Sync
3G data monitor (To test if I would go over what I'd use too much data from my allotment, refresh every 30 mins IIRC)
ATK (to kill tasks, hoping they'd use less of my precious bandwidth)
This 2 tasks plus sync just CRUSHED my battery, by the first time I turned on the screen I saw more than 50% drain from my battery, probably around lunchtime (probably 3.5 hours from the start of work). I turned off all 3 and, like you, I haven't conducted a scientific experiment since.
I tried something similar with overclock widget, but I had the impression that underclocking made the SGS really unstable. It freezed completely like 3-4 times a day. After uninstalling overclockwidget the device didn't crash anymore.
So how are the longterm effects (say, 1 week) of setcpu?
If anything I'd OC my phone, not the other way around.

The software probably isn't optimized for your usage scenario, I don't think an underclock, if done right, should be that bad, OC on the other hand...

I'm in the same boat, screen uses 80%+ of battery when the screen is on, as long as I'm not wasting battery when the screen is off and processes aren't running I have excess battery life, not to mention a spare battery, which I'd like to get more use out of if I could better my experience.

crap battery life
After countless tweaking, I found what is an acceptable battery management scheme for my HD2.
I thought: what parts of the phone suck up the most battery life (based on CurrentWidget)?
1) processor (1 GHz)... this is overkill for most applications. Basically I decided to dial this down to 384mhz which is rather acceptable using SetCPU. So basically Max: 384000 Min: 245000; scaling ondemand and set on boot checked. Under Profiles, I added Screen Off with Priority: 100, 245 max and 245 min. Set this ondemand setting.
2) I enabled Autokiller (downloaded from the Marketplace) and set to Extreme (150, 160, 170).
3) Under Settings--> Accounts & sync--> I turned off Background data (unchecked this) and Auto-sync as well.
4) Under Wireless & Networks --> Mobile networks --> I turned off Enable always-on mobile data (unchecked this) too.
Well, things are much better... with heavy usage (not a moderate guy here) I unplugged my phone at 8:30 AM and now it is 2:35 PM and my battery is down to 76% now. So basically I will be getting around 24 hours straight of moderate-heavy usage here.
Not bad?
Personally I wish that we could throttle the processor based on the mAh of drawn current. I think that 300-400 mah (according to Currentwidget) is way too high for processor usage? Not sure.
Any opinions?
wow that sounds sooooo slow, good for you though
I rather charge my phone everyday after work than turn my phone to 2005 phone then still have to charge it everyday.
Well that's great battery life, but I'd prefer it if my processor didn't suck more than the G1's 528MHz P.O.S.
I use a spare battery (8 bucks ebay) I make no attempt other than adjusting screen brightness appropriately, to conserve battery or resources. I have never had any issues. sometimes my spare floats around in my pocket two to three days unused mostly on days that I work that happens.
I learned the value of a spare shortly after I got my tp2.

I am not sure if you did enough there ... best preservation of the battery is if you actually TURN YOUR PHONE OFF and take the battery out... then when u need it, pop the battery in, use it, and again - take it out...
Who cannot deal with battery drain should get probably Nokia E71 sine its battery runs for at least 4 or 5 days with moderate use including navigation...

Actually, this isn't bad at all. I managed to get about 3-4 hours of Angry Birds to play this evening. Sadly enough, I work nights so I have no way to plug during the middle of the day. This is awesome and man, I only get serious lag during hard animation or graphics processing during gaming. By 10 PM tonight, I got down to 28% battery life before recharging now
Everything else is kosher. I am a happy dude now.
Screen Glows - Even on standby
Anyone else notice their screen glowing at night using Android. (Not bright enough to notice during the day).
When i turn off the screen using red button, I see a glow coming from phone. Seems screen isn't shutting off correctly. This will be causing unnecessary battery drain.
When i switch back to Windows then turn off, the glow isn't there. (Only on Android).
Anyone know a setting/hack to fix this?

Yeah, that doesn't sound right at all, but considering you gave no info what so ever on your build setup it may be next to impossible to help.
Ok, seems overkill but good for you.
for me, using ShubCraft 2.0 drop mode, stock kernel, no underclocking/overclocking/undervolting/overvolting, and just a little bit of display brightness tweaking I get 16 hours out of my phone with I would say moderate use. Probably an average of two hours mp3, two hours gaming, at least 90 mins talk time, about 30-40 texts, light 3G browsing and email use and probably an hour or so gaming. Obviously the rest of the time in that 16 hours is "standby" time. Even then I probably only get down to about 40% charge.

I've put Darkstone Froyo (no sense) 3.0 on top of my HSPL 2.08, radio 12, Ozz Rom barebone and DID NOT install SetCpu, nor Task killer, nor under/over-clocked or under-volted my CPU.
The result is 4-8 mA in Currentwidget on standby with data sync all the time, Wifi on (while in standby wifi gets disconnected automatically - you don't have to do anything), bluetooth and GPS off when I do not need them.
So, my battery delivers at least 24hrs of Anroid use without any tweaks or additional apps, just BARE/STOCK Android Froyo 2.2
I have realized that the "reboot method" is working. I'm running HyperDroid Sense 1.1 with Hastarin r8 together with Omega XT 17.2 and radio 2.15. The power consumption was 57-65 mAh in standby - but today I simply tried the "reboot until consumption is being reduced" method - and now it consumes 9-11 mAh in standby.
I'm using SetCPU with the recommended settings.
With other words: simply reboot the phone and check the consumption with CurrentWidget. After 1 - 3 reboots it should be reduced to an acceptable level.

Good point! - HD2 Tmous Running Android 2.2 mdeejay eVo Sense REVOlution build.
Runs fine in windows mode, but in Android screen continues to have dim glow when switched off. For the moment i've taken to switching back to windows to save battery life.
Any thoughts?

I have two flavors of Android that are currently my favorites. Great performance, no freezes fully functional and acceptable as an alternate for everyday use. One is phiredrop's Skinny EVO v1.5 and the other is mDeejays Sense rEVOlution v2.3. Both are based on the EVO ROM and both are Sense builds. After a lot of experimentation I have found battery life to be excellent with the following procedure.
Always boot your Android using Excellers Android loader. Boot up into Windows Mobile. Once it is settled in tap on the Exceller Loader icon but do not launch Android at this point, instead hit your home hardkey to light up the hardkeys then immediately tap on the Exceller Loader icon again and load your choice of build before the hardkey lights go off.
Once Android is fully loaded turn off screen auto rotation and disable auto brightness in settings. Then set the brightness level one notch below what is default. Do not use SetCPU nor any task killers whether they be manual or automatic. These are not needed for great battery life and can be detrimental to your performance and battery life rather than beneficial. Go to the Market and download and install CurrentWidget and set it to show on your main screen. Turn off GPS, Wifi, and bluetooth since you do not use them full time anyway.
If you spend most of your day inside of a factory as I do, or any other place where carrier signal is not good, get an airplane mode widget to put your device into Airplane Mode whenever the signal is spotty. If you have a signal fulltime then the airplane mode is not necessary as I have found the drain on the battery to be exactly the same with it off or on when I have a good signal.
Do all of the above then hit the hard end key to put your phone in standby. Let it set a couple of minutes then hit the key again to light it up, unlock it and take a look at the mA reading on your current widget. I think you will be pleasantly surprised at the results.
I am downloading SkinnyEVO v1.7 as I type. I will report back on the drain that this new build requires as it has a newer version of Haret, some folks are reporting that it causes severe battery drain.
By the way, when at home with good signal and Wifi turned on, this setup for these two builds draws only 4mA in standby.
Below are screenshots of two different EVO based builds and on two different days. It's not a coincidence folks, this does work. I also set 11.02.miui.english build up this exact same way and it was only drawing 3mA in standby also. Give it a try and let me know your results for your build. I would like some info specifically on the non-EVO builds, as well as Sense and non-Sense builds for this method.
One more thing to consider, I am NOT using hot reboot to get these readings. These are readings that I get on each and every boot with the method explained above. Hot Reboot is a handy tool to have installed if you have some crazy app that wants to drag your device down and won't turn loose, but it is totally unnecessary for good battery life.

I checked the CurrentWidget earlier today after upgrading the kernel to Hastarin r8.1. 9-10 mAh with HyperDroid Sense 1.1 and everything is working great.
I have the screen rotation enabled and use SetCPU paired with WatchDog (I prefer to receive warnings about processes running away).
I use the EBL to load Android immediately after WM has loaded and everything is working just great. I got the impression that I have almost a better battery life with Android now than with WM.

I have two flavors of Android that are currently my favorites. Great performance, no freezes fully functional and acceptable as an alternate for everyday use. One is phiredrop's Skinny EVO v1.5 and the other is mDeejays Sense rEVOlution v2.3. Both are based on the EVO ROM and both are Sense builds. After a lot of experimentation I have found battery life to be excellent with the following procedure.
Always boot your Android using Excellers Android loader. Boot up into Windows Mobile. Once it is settled in tap on the Exceller Loader icon but do not launch Android at this point, instead hit your home hardkey to light up the hardkeys then immediately tap on the Exceller Loader icon again and load your choice of build before the hardkey lights go off.
Once Android is fully loaded turn off screen auto rotation and disable auto brightness in settings. Then set the brightness level one notch below what is default. Do not use SetCPU nor any task killers whether they be manual or automatic. These are not needed for great battery life and can be detrimental to your performance and battery life rather than beneficial. Go to the Market and download and install CurrentWidget and set it to show on your main screen. Turn off GPS, Wifi, and bluetooth since you do not use them full time anyway.

Update: Nov 9th - I have tried the SkinnyEVo v1.7 and have had no luck in getting it to run. Even changed out the kernel to newest 8.1, tried it with the supplied data image and without. No luck at all, it will not get past the HTC splash screen. I wish there were a way to disable that splash so I could see what is causing the problem and get this thing to launch.
Anyways, I have now tried the above method the tytung NexusHD2-FRG83 v1.4 PPP/RMNET build and had the exact same results that I had with SkinnyEVO v1.5 and Sense rEVOlution v2.3. 3 mAh in standby. Works like a charm, now if only SkinnyEVO v1.7 would cooperate.

It really works, thanks!

After countless tweaking, I found what is an acceptable battery management scheme for my HD2.
I thought: what parts of the phone suck up the most battery life (based on CurrentWidget)?
1) processor (1 GHz)... this is overkill for most applications. Basically I decided to dial this down to 384mhz which is rather acceptable using SetCPU. So basically Max: 384000 Min: 245000; scaling ondemand and set on boot checked. Under Profiles, I added Screen Off with Priority: 100, 245 max and 245 min. Set this ondemand setting.
2) I enabled Autokiller (downloaded from the Marketplace) and set to Extreme (150, 160, 170).
3) Under Settings--> Accounts & sync--> I turned off Background data (unchecked this) and Auto-sync as well.
4) Under Wireless & Networks --> Mobile networks --> I turned off Enable always-on mobile data (unchecked this) too.
Well, things are much better... with heavy usage (not a moderate guy here) I unplugged my phone at 8:30 AM and now it is 2:35 PM and my battery is down to 76% now. So basically I will be getting around 24 hours straight of moderate-heavy usage here.
Not bad?
Personally I wish that we could throttle the processor based on the mAh of drawn current. I think that 300-400 mah (according to Currentwidget) is way too high for processor usage? Not sure.
Any opinions?

Max: 384000 ?!?!?!? then whats the point of getting a good , expensive phone with huge 1GHz proccessor !?!?!?
hello,
i realy have hight battery drain ... it's between 50 and 60 mA in standby mode no matter if the phone is on flight mode or data on or any other thing enabled ... so i said maybe it's some app that prevent my hpone to go in standby mode ... so i did everything from the start ...task29 +hspl+magldr+recevery ...after installing the hyperdroid v12 and befor installing any app i installed current widget and the same consumption 50 -60 mA ...i've read that in all the night and with flight mode the phone drain 2% - 5% ... for me it's 5% per hour ...
I dont know if it'as a hardware probleme or no but i thought it's my battery but i use 2 battery now and the same thing for both... i used many roms the hyperdroid is the less hungdry ... with cm7 v3.3.5 an amazing battery drain.
does the magldr or CLk have anything to do with battery drain?
I wanted to gauge battery life and stability on the CM7 Nightlys. So post your vote and then make a reply with the following info:

In 4 days I've only had 1, so not that bad to me at all. Then again, it may just be the hardware, as all of our phones all respond differently to everything.

I don't think I have ever had close to that. You must live right under a wireless tower or something...
I charge frequently, so I don't have a lot of long runs from which to take data, but this past weekend I decided to see how long I could run my Inc using its current setup. I keep things switched off unless I'm using them (like GPS, BT, etc) and at night when I go to bed, I turn off mobile data. This allows me to still receive calls in the event of a late-night emergency (unlike airplane mode). I don't need my phone to stay up-to-the-minute with emails and such while I'm asleep.

Stock HTC 1300 mAh battery - still had 7% left today after running more than 42 hours on a standard (non-bump) charge.
Usage was a bit lighter than normal, but I still made a number of voice calls, watched a couple episodes of my favorite shows, etc. So it's not as if the phone was just sleeping the whole time.
This was using Chad's 2.6.37 kernel (Feb 11 version) and SetCPU profiles

As you can see from my screen-on / wake time in those images, I'm not a heavy user of my phone. People who are playing tons of games and constantly syncing social apps can't expect to get anywhere near the battery life as lighter users. Custom kernels and clock speeds can only go so far.
I'm at 27% w/ 9h15m now
Which Kernel: Chad
Battery Size: HTC 2150
Current Batt. Life and Uptime: Normal Life is about 10-14 hours
What is on? GPS is always on, 3G is on except for the 3-5 hours at home in the evening when WiFi is on instead, 1 to 1.5 hours of Bluetooth, 3 gmail accounts in the gmail app.
I also use both Twidroyd syncing every 15 minutes for 1 twitter account, and Tweetdeek syncing every 30 minutes for 1 twitter, 1 facebook, and 1 foursquare account, Droidin syncing every 12 hours, and Scanner Radio running in the background...
I'm thinking my other battery is junk. I bought it off ebay as a 1750, supposedly that means its 1500. I think even if it is 1500 its not as high quality as the stock, so I am going back to stock until my new battery comes in.
Stock battery, incredikernel with smartass, .92 hboot, .19 radio
3g on, heavy internet and xda app, battery 27% after 9 hr 1 min.

Which Kernel: Chad Incredikernel.
Battery Size: 3500 mAh Seidio
Current Batt. Life and Uptime: 2 minutes. Freshly installed CM7 #3. Before CM7 #3 got 2 days 12 hours.
What is on? Wifi, GPS, bluetooth, 1 e-mail, 1 gmail, auto brightness. Everything syncs in 15 mintue intervals.
Which Kernel: Invisiblek
Battery Size: HTC stock battery (1350 I think)
Current Batt. Life and Uptime: Normal Life is about 3-6 hours
What is on? GPS is always on, 3G is on, 3 gmail accounts in the gmail app.
I am down to 26% after 2h and 26m.
Tasker seems to suck most of my battery life (25-35%).
I dont play many games or surf the web so I dont know why this is happening. I used to get between 12-16 hours on CM6 but I ran juice defender which I think helped a lot. My tasker profiles are triggered by location and I think that when I am indoors it has my gps running, but looking at the battery info this does not seem to be the case..
Which Kernel: Slayher
Battery Size: 1800
Current Batt. Life and Uptime: 54%; 10 hours up
GPS on but not used; I used 3g the whole time. 1 mail account, weather/news widget updating and probably some other stuff too

Holy crap - that is completely unacceptable.
Not only is that awful battery life, but Tasker should not be using that much power. I use it a lot and have never once seen it get close to that.

Sure sounds like it: I can't think of anything else Tasker does that would suck up that much power. I would suggest you refine your location profiles to use non-GPS methods (such as the Wi-Fi Near state).
If Tasker is trying to lock down a GPS location and you're indoors (or somewhere else where GPS reception is poor), that is a sure fire recipe for bleeding your battery.
