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

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).

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.

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
---------- Post added at 04:24 PM ---------- Previous post was at 04:22 PM ----------
crap battery life
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.

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.

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.
OK after i got my Arc S i already saw better battery than my old X10.
but after a while it started to get all "android" on me again in terms of ****ty battery.
after using better battery stats and digging all the web for solutions on the subject (yes i got pretty obsessed about battery ever since i had android), i've pretty much found out 3 simple stuff that pretty much takes up most of your battery on standby and even actual use of an android phone.
before i did that i woke up 8 hours later just to find out that at night on standby my battery ran from 100% to 86-90% when i woke up. (on my x10 i woke up with 76-80% lol)
keep in mind im a very heavy usage user on my android and i do literally EVERYTHING ON IT.
anyway 3 simple stuff to do:
1. log out of latitude, drains the battery like crazy.
2. disable auto sync for gmail, contacts and regular email (i use hotmail so i use the email app, dont have gmail)
3. be connected to your home or office wi-fi as much as possible.
keep in mind i do have whatsapp in the background and other regular apps that still ran as a service but they dont drain battery much apparently (i thought they were always the problem btw)
i unplugged my arc s from the charger with 100% fully charged battery at 4am and went to sleep..
..woke up 11 hours later at 3pm (yes weird day lol), had 18 missed calls, 6 sms messages and 5 voicemails which means the phone had the screen on for each call and the speaker played my ringtone every call and sms and even voicemail notification plus i had my alarm clock which i kept pressing the snooze on..
i was amazed to be with 96% after 11 hours!!!!! OMG
at the same day at 11pm i was left with 27% battery after all day had 1:20 hours voice calls, 2:50 hours screen display on.
i was also outside and im always on 3g and also used my gps on google maps for about 20 min.
finally happy about my frikin battery on my android device !!

"If you want to save battery on your smart phone, don't use it as a smart phone."
Of course background services will use energy, but I have them on for a reason.
The best battery saving tips (for those who use their phones)are brightness and keep an eye out of resource hogs and unwanted background services (Facebook app).
I found that rooting and removing all the bloat-ware vastly improved my battery life as it gave more RAM which meant my phone had to do less memory management.

If you have a android and have done the registration on the first time, you have a GMAIL acc.
Btw, add this solution. Works for every phone.
- Go to WiFi & network settings > Mobile Network > Networkmode > Set it to "ONLY GSM"
this will make the mobile-antenna to find one connection and stand there (Mostly this gives the best signal strenght), but the WCDMA and WCDMA/GSM will search for other connections all the time and consume more battery
the only negative side with GSM is that your calls will connect 1~2 sec. slower compared to WCDMA and if you fall out of the signal range, youre out untill the antenna finds new one (but the strenght is good so dont worry)

Or you can set it to WCDMA only. Setting it to GSM only would be disadvantageous as most smartphone users need a data plan and 3G has far better internet speed.
Turning off the auto sync helped me a lot. I just manually check my email at regular intervals.

Seiously, these are all the most obvious "battery tweaks". Tose are the first things that would come up in my mind...
I can safely say it's not a definite solution.
Most if not have already turned the Auto sync off.
Latitude for most users doesn't run to start with and even in some cases not even
installed.
Wifi and HSPA is a given this is pretty much ON all the time for most since were power users. (6gb data plan) can't complain for 20$.
Bluetooth in some cases but rare.
Full charge your phone and if your a power user within 14 to 16hours your usually left with about 10% battery usage.
Take into consideration that this is a rooted Xperia Arc S with bootloader locked.
If I leave it alone fully charge when I go to bed and wake up in the morning I usually have about 7% gone in roughly 8hours of standby that is taking into account your have the standard 1500mah battery.
I would highly suggest getting the 1700mah MUGEN battery it's worth the extra 50$. May not make much difference for some but it does for other.

Nothing new actually. In standby/idle mode I loose hardly 4-5% in 7 hours during night.
These are the most common battery tweaks.
In fact if the phone is alive (with 10% left) after 20 hours of heavy use, then i am happy.
With my Rooted device with 0.58 firmware, i get a 18-20 hours [brightness set to 40% always] of heavy using that includes, 2hrs of browsing on WiFi, 2 hrs of music, 40 mins HDGame, 2-3 hours voice call, 30-40 mins of video (occasional) and i check email in every hour and and reply, so that's good for me.
I appreciate you sharing your advice, but there are some points that are not so convenient and here is why:

Why not leave the phone plugged in while you're sleeping?
Stock Arc battery has overcharging protection, which means that there is no risk harming it if you leave it on charger for 8-10 hours.
It will charge to 100%, then decrease to 95% and start charging again.
As a matter of fact, those small charge cycles can turn out to be beneficial for the new technology Li-Pol batteries.

Agreed.
But there are cases when people use Latitude to their convenience.
For example, I tend to leave it on while travelling and I've taught my father how to use it on his (my old) X10 so that he won't have to call me all the time to see where I am.

Now that just doesn't make any sense.
One of the major Android features is that you can get your Gmail messages instantly and, in some cases, even substitute text messaging altogether.
I have 3 Gmail accounts on my phone and they are in autosync 24/7, because otherwise my phone is pretty much as useful as a Nokia S40 phone.
Not to mention that polling (refresh at a specified rate) drains way more battery than push notifications which Gmail utilises.

Agreed.
Especially in low signal areas, WiFi can save battery because the phone doesn't constantly trying to establish data connection. However, forgetting to turn WiFi off when leaving your home or office hotspot range can result in even bigger drain, as the phone will intermittently look for available WiFi hotspots.

Personally, I feel you are sacrificing vital features just to stall your battery meter.
This is not as wise as you make it appear to be, because if each one of us carefully considers it, we will realise that there are very few hours within the day that a plug is not accessible. We have cars -there are car chargers, we are at home -obviously there are sockets, we are at the office -there are PCs thus USB ports. Heck, I've even charged my phone on a DVD player with a USB port in a presentation room once! In my opinion, it's about time we stop whining about how "our old phones lasted a week even if we were playing Snake all day" and adopt new charging habits.
Then again, how one uses their phone, it's their business.
However, the thread title can be considered misleading, as I reckon your advice is respectable, but in no way a widely applicable solution.
If I'm staying over at a bud's place/gf's place and have no charger/microusb handy, or I'm out and battery is running low, I do one thing:
1. Turn off data (I use a nice on-screen toggle for this).
This alone lets my battery last faaaaar longer.
Why dont you but a nokia 3310 and stop whining?
the reason we buy these phones is cause of the amount of things we do on them. disabling these features is just pointless and turns the phone back intoa dumb phone

I'll start off that I'm a novice android user, I got this phone a month ago and before that I was using a Nokia E63.
Anyway, so I rooted and all that junk, did a factory reset and all that junk, and now my battery is complete garbage on idle.
Before I rooted, when in idle for 8~ hours, the slope was very minimal and I lost about 1-5% battery life. Now, the battery is draining like crazy, to the point where I have to charge several times a day.

OK, now this is strange,
at first I thought it was fixed; what I did was update Google Maps. After a few hours, the problem of "google services" came back...
help!!
Keep your phone connected to Wi-Fi while you're sleeping and it will drain much less (I've sometimes seen <5% over 8-10 hours). Keeping your phone on network will continue to "wake it" during the night.
Get GSAM Battery Monitor or BetterBatteryStats to get a better look at exactly what is draining your battery so quickly.
It has to be one of the Google apps running on the background. Like somebody mentioned, get better battery stats to see what's exactly draining your phone. Also, I've noticed that if I keep NFC enabled, some apps that utilize it, will kill my phone way faster. So check NFC maybe, try disabling it and see if it makes a difference.

Well before I rooted there was absolutely no problem with battery. I use a $15 tmobile plan with no data. I basically use my phone like a tablet. NFC and most other features are disabled.
I'll give that other kernel a shot once I figure our how to do all this...

I had the exact same issue, and there is a problem with the Nexus 4 in that some applications stop the phone deep sleeping, even though the same applications have no issues on other devices. This keep awake seems to happen lower down and isn't recorded in Android as the phone being awake. The same issue appears on Franco kernel (I've tested it) as well so that isn't a fix if this is the problem.
Follow my post here to see if you are affected, then work to find the problem app. http://forum.xda-developers.com/showthread.php?p=36100401#post36100401
If anyone wants to test this with other kernels then:
Download CPU Spy. Reset CPU spy timers to zero, and first check the phone is deep sleeping by leaving for 30 minutes with screen off and USB cable unplugged and confirm Deep Sleep is around 90% or more. Now download Snowfall Live Wallpaper and set the wall paper as active, repeat the above, and see that Deep Sleep is never entered into. Use your favourite battery stats checker and you will find no indication of wake locks. Snowfall Live Wallpaper doesn't even have permission to keep a device awake.
Next set a different wall paper from the stock options (live or static) and repeat the test, note that Deep sleep is STILL not being entered even though the live wall paper is no longer in use. Now from the list of cached processes, remove the cached process for the Snowfall Live wall paper, repeat the test, and now the phone is entering Deep Sleep. So this particular wall paper has the power to stop the phone deep sleeping even when it is a cached (and so stopped) process. Another application that causes this bug is BeWeather & Widgets.
Even un-installing the problem application doesn't return the phone to be able to deep sleep, as the app is still a cached process. This can make it difficult to find the app causing a problem.
Testing these applications on a Nexus 7 and HTC One X causes no issues with the device deep sleeping, ergo, Nexus 4 bug. I'm sure there are other applications causing the same issue.

The stock kernel is garbage is what it is , install Franco kernel and forget u ever had this issue , rooting your phone didn't cause battery drain like u said ..... Google services could be anything , check your maps app setting

It is not garbage at all.
The op must have too many background apps running. Probably has nothing to do with the kernal or rooting..

I have wifi on almost all the time and I get a full day, 5 hours screen on time. I use franko kernel and aokp.
Google services must be something like lattitude reporting your location, or an app that polls data all the time. Even with
auto sync on, whatsapp syncing and wifi on all day I dont have google services anywhere in my battery list.
Of course, it is entirely possible it is something to do with google now, which I have turned off

My "multitask" button menu is always empty. I never keep anything voluntarily suspended in the memory (if that's what your talking about)

I originally hated Google Maps (before I rooted) because it used up about 1-5% of my battery with GPS and all other related settings disabled... no problems at all with battery back then. I basically did the same thing after I rooted, but then I started having the Google Services battery problem, where then I re-enabled most of the Google applications I disabled (maps, books, magazines, wallet) and updated them, hoping for Google Services to be satisfied, but nada.
Anyway, today was TERRIBLE. I need to keep WiFi on all the time otherwise Google Services eats my battery. But at the end of school today, I looked at my phone in horror to see that Google Maps took a huge chunk of my battery (and 3 hours earlier there was no trace of Google Maps in the battery status settings)
Battery life today : the bad stuff started happening once I left the mobile service area. Google Maps did not show up on battery settings before that time.
Keep AWAKE FOR AN HOUR???
still not sure what this is, 5% from this app basically translates to another 30-40 minutes of battery life
acceptable wifi usage
CPU SPY:
I just disabled the Google Location Services, I wonder if that would change anything... could it really be that simple? Unlikely.
As for applications, I don't have many... and I don't have a live wallpaper or anything. I keep my phone on the lowest brightness indoors and automatic outside. I try to save every bit of battery I can, and a useless wallpaper or running application doesn't help with that (I uninstalled a few apps like FB that kept on running in the background)
I wish I had 20 hours of battery life... My N4 is empty after 6 hours on CM10 with Francos kernel.
Freeze Maps
How comes most people in this thread are getting 4 hours + and I can barely reach 2 hours , I have most of the advanced features turned off, AOD off location on and I keep my brightness below half. Any suggestions would be helpful
I am not rooted on stock rom

I do have the same problem. 6 moths device and not even 3h. The first month it was like 7h
The phone seems to bug out due to wakelocks, which tend to be very inconsistent. One day I'd get amazing life - about 70% left after a normal work day (let's say 10h in total) with 1h+ of SoT in that time. Most of it is idle drain. With such idle drain I could easily get 6h of SoT with active usage, or even 10h if I watch videos all day long.
Other days I'd get Google Play Services on the top of my list, above my screen usage. I started checking for wakelocks with Better Battery Stats and usually I get absurd information, such as Bluetooth wakelocks while I NEVER use BT and never turn it on for any reason. The solution was to use a package disabler and disable bluetooth and all related services to it. Then, I'd get a Viber wakelock. This ****ty app keeps my phone awake for 20-30 minutes at random times of the day for no apparent reason. I am going to delete it completely when I get my grandmother to use Telegram to contact me. Literally the only reason I am using Viber.
Anyhow, check your wakelocks. If you can't find the problem - log out from google accounts, update Google Play services to BETA, delete dalvik cache through recovery, delete system cache from the settings, then log back into the device, restart again and charge it up. You should start seeing normal idle drain after that.
Last time I did that, I was getting 60-70h of standby time with wifi and LTE on during the weekends. Then today, Google services drain once again out of nowhere (this is where I disabled bluetooth completely as well).
Now, after my last charge, I get 93% of deep sleep, which is good. With bad wakelocks it can go down to 50-60-70%, which is very bad.
I wish we didn't have to go through such annoying maintenance, but Android is still a b*tch when it comes to battery management and basically does what it wants, when it wants to.

To be fair, this is more of a Samsung issue than an android issue. My LG phones never had such inconsistent battery/wakelock issues. Sure, I destroyed the batteries by having them plugged in overnight on fast chargers, but at least they consistently got worse XD. The V30 loses about 10% in 24 hours on standby. A little bummed, I moved away from LG to have a phone that just "works" after a ton of issues I've had with them, but it seems like Samsung has its own quirks, such as random wakelock issues, lack of google assistant support with screen off, and the worst headphone jack I've ever heard.

Thanks for the advice however you need to be rooted for most of them steps, I don’t intend on rooting as of now. I think I’m going to wait and see if they can fix the Color gamut on the pixel 2 via a software update. Seriously considering changing phone because of this

That's not true - I am not rooted and don't plan on rooting at all. To use better battery stats with stat permission you do not have to be rooted, you just need USB debugging and ADB command prompt. The only reason to get a new pixel is for the camera and at that point you are better off buying an actual dedicated camera.
I would not even consider the pixel 2 even for a second as a replacement for the S8. The S8 is of much higher quality and standard. The new Pixels look like complete rip-offs to me. Better buy an iPhone 8 than those.
Also, consider a full factory reset. You can also try the phone in Safe Mode to see if battery drain persists like it does normally. If it does - return your phone for replacement, it's a bad unit. If it doesn't you know for sure that it's software-related.
If you believe that the new Pixels are immune to these battery issues, you are in for a surprise. ANY android phone on stock firmware can suffer from this. The old nexus phones are first that pop-up when I search for battery problems related to google play services and wakelocks.
Basically, investigate your problem and resolve it, then you will be a happy user.
The screen is only consuming 7% of your battery usage, so clearly that isn't the problem. Considering that your highest battery consumer is the screen at 7%, you have a TON of little apps/services that are each consuming a small amount of battery. I'd wager that if you factory reset your phone without reinstalling all your apps, you'd get 5+ hours SoT without a problem.
Here's what you do in order: stop with the procedure once you are satisfied with your SoT.
Download and set up GREENIFY
Uninstall all unnecessary apps. I get almost 7 hours SoT, and I think part of the reason is that I only have about 70 apps installed, total.
Factory reset without reinstalling your apps. Only reinstall what you consider essential, and be very conservative with what you download.
LMK what works for you.
I don't think greenify works well for this phone at all. In fact, without root I think it works pretty bad for any phone.

If you're referring to the screen issues the Pixel 2XL has been having, I wouldn't hold my breath. It's a manufacturing issue with the OLED panels that has plagued the LG V30 as well (LG produced OLED panels for both phones at around the same time). I had the V30 for just a few days before wanting to throw it at a wall from the display issues, and that's why I'm sitting with an S8+ now lol.

Okay I have just download gsam battery monitor and I have enabled more stats through ABD I will post back with some screen shots later on to see what's eating my battery
Update here is the results from gsam. Still crap battery life
I think it might be your signal. I'm getting a solid 5hrs SOT continuously playing games and playing vids on YouTube at 2K display. The attachment might be on my 1080p testing time but now I'm always on 2K display as I find no significant difference in battery life. I'm always on Data. Never really on Wifi. I don't do screenshots anymore as I am satisfied and have no need to monitor it.

My signal never drops lower than 2 bars most of the time I have full signal also I still get pretty poor battery life on airplane mode. So I don’t think it’s that

If you don't want to factory reset. Try this.
Reset App Preferences. (Settings > Apps > Three Dot Menu)
Clear Cache
Clear data and cache of Google Play Services
Turn off any Location Services on the Google App.
Let the device sit in for a while so it can "reorganize" everything and observe.
Shutdown the phone and enjoy.

Thank you for your suggestions however I have tried all them things in the past with no change ... I really don’t want to factory reset ether .
To be honest, in my experience it's Facebook, messenger and snapshot. Twitter and Instagram too. Those apps keep your phone awake most of the time. They are poorly programmed and are constantly sending data.
With those apps installed screen on time gets less relevant as it's consuming almost as much battery when screen is off.
Maybe try uninstalling them for a day and see if it makes a difference.

Greenify didnt work well on my S8, but used a package disabler and set up phone as per here https://www.xda-developers.com/the-...r-community-radically-improved-my-experience/ and my phone is now great in terms of battery life, 6 to 7 hrs SoT, 60 odd hrs between charges.
There is no need to package disable that hardcore, really. Without a disabler I was able to achieve 0.3% per hour, although this is rare for me. At my office, due to bad network connection, I get about 0.9% per hour. At my home it's usually between 0.3 and 0.7% drain per hour. It's not bad at all for my needs.
My current setup is WITH a disabler, but I have disabled very specific things. For example, I use a lot of Samsung apps like Health, Notes, galaxy app store in general, sometimes calendar and maybe 1-2 others that are rare to be used. I still use Bixby whenever I want to control the phone without a lot of effort, or for macro quick commands that chain events one after another. I don't want to deny myself this functionality just because of a placebo effect.
Here is my idle drain with this setup (with 1h 10m of SoT at the moment of the screenshot):
https://drive.google.com/open?id=0Bwg-0GLG0gP9QTd0ZUZKWklKNGs
At this rate, I'd get more than 80 hours as the more the idle, the bigger the prediction becomes. This is with Wifi/LTE on (wifi in use with not the best signal too as visible from the screenshot) and on the Optimized setting mode. With Max power saving it would probably go well beyond 160-170 hours, which is pretty good with an active network connection. Regardless, I sit on the default optimized mode all the time and have zero problems with performance or bad battery life.
On my disabler I have disabled SPECIFIC services in ALL apps that might have these services:
AppMeasurementService
AppMeasurementJobService
Firebase... anything that starts with Firebase
These services are found inside packages. BK disabler lets you turn them on/off individually. The ones above are responsible for many wakelocks, and the services are only used to collect usage data. It's best you disable them, both for privacy and for battery life. I eliminated a lot of my usual wakelocks by doing this. Dig in almost every app you use, because they appear in surprisingly big number of apps.
Packages I have completely removed with ADB uninstall commands - anything related to Facebook + 1 carrier bloatware app.
Packages I have disabled with BK:
Bluetooth (I don't use it at the moment and it enforces some inexplicable wakelock without any sense, so i disabled it and wakelock has been gone since)
BluetoothTest
Finance (yahoo widget bloat)
Sound detectors (I do not use bixby wakeup and see NO Reason to have this enabled whatsoever - it is usually active - suspicious to say the least, how about we go without it)
Weather
That's it. With this setup, Deep Sleep is indicated to be 95-97% from Better Battery Stats overnight. I don't see a single reason to disable 50% of the rest of the phone when stats are already this good. Why bother? Use your phone freely.
