cm 7 on x10 battery life is horrible - XPERIA X10 General

I just recently flashed my phone to gingerbread 2.3.3 (cyanogenmod 7.0.3) and my battery life took a turn for the worst.
It used to last 24 hours or more, but now it only lasts 6-10. It even does it when the screen is off at night, ill wake up and turn it on and its dead.
Also if it helps my kernal is 2.6.29.6-b11.
(yes i am a noob)

there has been long discussions regarding problems with deep sleep (state when phone uses very little cpu when screen is off), this cud be a reason for ur bad battery life, also if ur using any custom kernels. to see if ur getting deep sleep, download an app called cpu spy from market and that tellse u how many hours deep sleep ur getting. or it cud be something else entirely, ive always stuck to a custom stock 2.1, so i cant really advise too much. search for deep sleep and follow ny instructions provided in those threads.
edit:
have a read thru this, it might possibly help u http://forum.xda-developers.com/showthread.php?t=1100786
edit again: try disabling automatic time and date set up to manual, as ive heard some people had some acces doing this, but as i sed have read thru that thread.

tried to use cpu spy but it FCs on my phone. unchecked auto date and time. im looking into other kernels that may yield better battery, havent found 1 yet that addresses deep sleep issue.
thanks for suggestion dude

Is it the new version? Cause my battery is good.

Hey, I've also heard of a bug in Google Maps. It is continuously running without letting the phone sleep. That's my problem with my battery right now.

seem to have fixed it, i turned auto date and time off and bluetooth and the battery lasts MUCH longer, 24hr plus!

Horrible battery life on EVO after rooting

Hi all,
I folowed both part 1 and part 2 to root and unlock nand on my evo. I loaded the freshevo 0.3 ROM and applied the 4g fix from flipz. Now, my Evo lasts about 5 hours in standby before the battery is dead.
My Evo used to last most of the day before I rooted it. Has anyone experienced similar issues?
Thanks,
Rayden1000
Did you flash the new radio?
Did you leave 4g on?
Gps?
Bluetooth?
What are your sync settings for social network, weather, news?
We need more info than my battery sucks.
Flashed the new radio.
4G is on - as before rooting.
Bluetooth, WiFi is off.
GPS is on - as before rooting.
Syncing is at 4 hour intervals.
Exchange is "as items arrive" - as before rooting.
I know that everyone complains about the battery on the EVO, but my phone is dead after just a few hours of non-usage.
My Up time and Awake time are almost the same, so I think something is preventing the phone from sleeping. An hour ago I went to some setting that listed which app is using what percentage of the battery. I can't remember where I went to check that now, and it wasn't the stock battery settings app. It said that HTC Sense is using 97%.
Thanks,
Rayden1000
Try this

Also you might have a bug with 4g where it is constantly connecting or trying to connect. See if the fix above works. If not try damagecontrols rom and see if its any better. Or you can try disabling 4g and see if there us a huge huge huge gain.
I do know that right now some of the custom roms have had 4g issues. I'm not in a 4g area so its hard for me to test.
Thanks Aridon,
I already checked out that thread, my phone is set to CDMA auto.
And yes, I did have the 4g bug when I unlocked NAND through method 2. I found the fix that flipz posted and that has fixed the 4g issue. I also flashed the freshevo 0.3 rom that has the 4g fix built in.
I will try flashing the 4g fix again right now, but does anyone have any other suggestions? It seems that battery performance decrease is a common issue after flashing custom ROM's.
Rayden1000
You should consider doing the steps in that thread regardless if what it shows. The hero had a display bug in that regard for some and perhaps so do some evo. Seems odd but there are differences because when you start playing with kernels it will boot on 002 devices but not others so there are differences.
I'd do it, set it and reboot. Don't go back in to see if it changed just start a new battery test And check for improvement
turn off 4g, my evo has everything yours does! but end of the day i get home and still have over 50% battery life left! if you have 4g on it drains the crap out of battery. only turn it on when your going to use it!

I do understand that 4g decreases the battery life significantly. What I am trying to say in this thread is that after I rooted and unlocked nand on my evo, the battery life is MUCH MUCH worse then before rooting. My phone's battery now goes from 100 to 0 in about 4 hours - while I am not using it at all.
I am just trying to figure out what process is running all the time and prevents the phone from going to sleep.

Dude download Overclock Widget. Do a google search for: Overclock Widget HTC Evo.
I swear on everything I love that after I installed it and went through the settings my battery lasted 11 hours today. I still had 23 percent left and I streamed some videos on the web, listened to music, played around all day with my phone. It really works and some people claim 30 plus hours of battery life.
It works and I will post a screenie tomorrow of the proof.
Whatever it was, installing Damagecontrol 3.1.2 ROM "appears" to have fixed the issue. My phone has been in standby for about an hour and I have 93% battery left. I will leave it alone for the night and will post the battery status tomorrow morning.
Thanks to everyone for trying to help.

Baked snack ROM in my observation gets THE BEST battery life of all the roms out thus far.

I may have spoken prematurelly, this morning the battery is dead again. I have tried numerous ROMs with the same result. I also tried old radio ROM ans new radio ROM.
Has anyone been successful at following both part 1 and 2 of rooting and maintaining decent battery performance?

Not to sound noobish, but did you already disable GTalk auto sign in and then sign out?

Did you NOT just read my above post. I clearly gave you a fix SMH. Here's proof of what I'm talking about:
I took a screenshot with the ShootMe app. I'm currently running Fresh's latest ROM. The screenshot indicates that I had it off the charger for over 14 hours. I used my phone today to send a lot of text, skyfire, streaming flash websites, etc. By the way I have about 40-50% battery left.
Installed overclock widget, set it to run at around 247 mhz at all times - same result. Evo battery is dead after about 4-5 hours. Does anyone have the original ROM for the Evo? I tried running the RUUxxxxx.exe files, but they all fail - probably due to me rooting and unlocking nand, therefore modifying the file system.
Rayden1000
I've been running Fresh 0.3 for a few days now and haven't seen a problem. Have you tried getting a task manager and making sure there isn't a program running in the background causing all this? Also, is your phone hot... if it is, it means you go something taking up some major cpu time.
I had a similar issue with my Hero, the cause was it was trying to sync the calendar over and over non-stop. You should look at your account syncing also, there could be a problem there.
Sounds as if you have something running in the background that is killing your battery. When you are flashing your roms, are you doing a wipe first or just flashing over whatever you had before?
I don't see how you're running overclock widget and getting bad battery life. Download Advanced Task Killer and kill those tasks.
I also had an issue like that after installing some ROM (I forget now what one, since it was a while ago) and my battery died over night while I was sleeping. I don't really know how (if I did) fix it, but I wiped everything, factory/data/dalvik/battery stats (whatever that is) all those options, then installed a new ROM and it seemed to work fine.
As for the overclock widget, I downloaded that and tried to use it, but it didn't seem like it worked. It just didn't seem to stick and I didn't really see any increase (maybe even a decrease) in battery life. Probably the best thing that you could do is get a task killer and see if there is something running that needs to be killed. The awake time shouldn't be anywhere near the uptime

FIX and INVESTIGATION: Android OS (battery drain) problem on Gingerbread

CASE CLOSED!!! Please read bottom part or flash stock GB 2.3.4!
I have posted this already on another thread (almost word for word) but I just really want you guys know and not panic about this problem and avoid going through difficult fixes like deleting system apps, recalibrating battery or even resetting your phone.
Since JVK was released, many observed that Android OS sometimes get hungry and devours battery. For some reason it is triggered to go berserk. Others say that the main culprit is the Auto update app. But other apps like Google Maps, Latitude and even just in a place where there is very low network signal or Wifi reception could also trigger this problem.
Now, I have a very simple solution: Turn off device, remove battery for a minute, put it back then turn it ON. Yes it is just that simple, REBOOT YOUR DEVICE.
Yeah after you turn on your device Android OS is still on the top of the list with high percentage but I believe it is just as it is because it previously consumed a lot of battery. All you have to do is observe again for an hour if your battery is dropping again, look into the graph and see if it is still steeping to the bottom. If it is dropping like Mt Everest, do the procedure above again.
If not, you will observe that after a couple of hours Android OS's percentage is getting low. Problem is fixed, (temporarily though).
Why go through deleting apps, recalibrate battery etc when you could just turn off your device for a minute?
I have experienced it a lot of times already (one of the first users who upgraded to JVK) but it doesn't bother me anymore. Turning off then on your device is very simple ain't it?
I highly advise that you do not touch anything on the sensitive part of your phone as there is no known single root of this problem. Just like I told you, many situations or apps could trigger Android OS to go berserk. Until there is no definite solution to this problem, I suggest you do the above procedure and save yourself from going through the pain of removing system apps, battery calibration or even hard reset.
By the way my battery usually lasts 3-4 days unless I made Android OS angry again.
INVESTIGATION
INVESTIGATION CLOSED!!! The culprit is caught. But the fix is not so simple. Only Samsung and genius devs (apparently the fix requires closed source modification) could fix this. If the problem occurs on your device, just do the temporary fix above. Please do not try to mess with your device for now.It is now fixed in XXJVP 2.3.4!
Click HERE and read the bottom part for more details.
All this is due to Tatsuya who pointed us to the right direction. A big thanks to him for helping us in this investigation. CASE CLOSED

Ok thanks for the credits.
This previous link I gave explains how you can use watchdog to alert you when this bug triggers, so you know when to reboot your phone to stop this leakage (if you really want to stay on gingerbread until a fix is made by Samsung).

Guys if you want to help out please please please dial this *#*#4636#*#* and check "Usage Statistics" and let us know the top 3 items on the list! (highly suggested by {Angel}).
Below are some of the possible culprits currently pointed out by some users (I will update the list based from your feedback):
1. Software Update service
2. Google Maps
3. Latitude
4. Low network signal
5. Very low WIFI reception
6. Auto updates in Market
If this helps, a simple thanks is enough

Those of you with high drain, you can also check battery history through *#*#4636#*#* and see what you have under other usage 'running' and see if your phone as not been sleeping lately. I get this occasionaly with froyo and I suspect many people do also. A reboot fixes it for me, after that my battery usage is superb, but it's annoying as hell.

Yes just like I said in the first post, this is just a temporary fix. But I think users should just do this rather than touch anything on their phone unless they really know the source of the problem.
That is why I suggested that they report what could be the possible triggers, like apps or situations, that make Android OS to awake and gobble up the battery. If we could just pinpoint those triggers maybe we can now figure out the root of the problem. Your fix of removing a system app, the auto update app, is not even the single source of the problem. We just do not know if that app is an essential app or not. Sooner or later you will have that problem again.
I am not saying we should just sit and wait. All I am saying is if you are a plain user and you do not know the exact root of the problem, then just do what I suggested. But if you are a dev and is exploring the root of the problem, then do as you like and we will be most thankful if you find out the answer.

Rebooting works, and it seems to be working until you start some apps again. I have the same apps installed as I had on JPY, but JVB drains my battery dead in half a day.

Could you pinpoint some apps? I will update the OP to keep track of possible culprits so that others will avoid triggering this problem. Thanks!
I once saw that the battery drain from 95% to 9% after one night, and the android os used most of it. I rebooted my phone, and the problem has gone away, since. Happy with Gingerbread!
I'll give it a go! thnx

It is hard to figure out from the above apps or which is the most probable suspect. Just incase the problem recurs on your phone, dial this: *#*#4636#*#*, Go to Usage statistics and Battery Information and please report back (include also information on the Battery Use in Settings).
I hope we can help others avoid having this problem until there is a fixed solution.

Did what you suggested and pulled the battery at 30% waited 5 minutes and put it back in.... 1hr later it was at 35% (WTF!) and 30min later it was at 38% (WTF!)
im assuming its recalibrating?
Not necessarily. Maybe the battery meter is anticipating the fast consumption rate of Android OS that is why when it got fixed, the meter is able to readjust the readings based from the current consumption rate of your phone. Good to know it helped
Maybe use the 'forbidden' task killer? Works for me... Maybe im imagening it but works.
Btw my battery goes quickly down after getting below 25%. My battery not calibrated? Should i.calibrate it? I have this program to do it but am afraid that calibration goes wrong. (example what if my battery is 95% and will calibrate to 100. What if.i charge my battery higher than this.. Will it show 104%? Or will android stop working for it cannot be displayed in the notificationbar.
Using cm7.
Sent from my HTC Desire using XDA App
You do not have to recalibrate. Cm7 has a known issue about battery. I think you cannot charge past 94 or 95 percent and battery usage is a bit terrible. Please refer to cm7 thread for possible fixes, (the last time I checked their thread, they say it is probably kernel related).
Just turning off, pulling the battery and turning on does do a lot for me! i went from 10% per hour to only 1%! great thnx!
Hi,
About battery drain in gb, once fixed the wifi sleep policy issue ( by setting it to "never") u shouldn't have batt drain, but i've installed green power ( juice defender do the work too i think) to get some wifi management possibility back and it improuved my batt life.
But never the less, my battery won't last more than one day of hard usage ( being hanged on xda all day long, for instance ;-)
Sent from my GT-I9000 using XDA App
Guys, just turn off the task killer, it helped in my case. looks like its not working well on ginger
Rebooting works just temporarily.
It will come back the next day or so.
This is not a solution at all tbh.

Guys, on Gingerbread I've had battery drain two times:
1. Had about 14% drain in 3 hours all of a sudden, without doing anything at all. Just started going down for some reason.
2. This morning, saw about 40% drain in 7 hours..
And, both time I solved it by Clearing Memory from the Task Manager.. Went back to normal 2-3% drain per 6-7 hours after that..
So this might also be a solution. Go to Task Manager, RAM tab, and Clear Memory..
i'm on ginger also and my battery acts weird. 2 days ago i charged my phone over night while it was closed. the battery holds for 15 hours with massive use.
last night i did it again, but today it went from 98% to 80% in about an hour !
this is really weird.

Did you manage to check first what is running on your device by looking into Battery Usage settings? I think you have a case of rogue application running in the background.
If you have not rebooted yet could you please attach a screenshot of the battery usage list and graph? In that way we might possibly identify the app running prior to the clearing of memory. Thanks!

Ridiculous ICS Battery Life

On Friday 1 June 2012, which is Friday last week at the time of writing, I gladly updated my phone through Kies after receiving word of the UK update being available from these very forums. Over the past week, I have noticed that my battery life is considerably worse since my upgrade to the new Android version and, when hearing of people hear who manage up to 36 hours of battery life through this phone, I really want to find out what they are doing exactly. At present, I have set the brightness at 1% (the minimum) and only up it to 40% when out in bright light conditions. At home, I also use the Screen Filter app which dims the screen further (I have this set to 50% of my already 1% brightness setting) and claims to improve battery on AMOLED devices. I also have Juice Defend Ultimate running on "Aggressive" mode along with the built-in power saving mode running as well. Yet, looking on CPU Spy, my phone still does not enter deep sleep which is needed to see a real improvement in battery life as far as I am aware. I have tried restarting the phone and also plugging it back into charge before unplugging it with the screen turned on as many have recommended. Any ideas what else I can do?
Uninstall juicedefender. Its not uncommon that it drains a lot more juice than it saves.
There is must be any Application that is hogging your battery.
Install better battery state... Find that application and uninstall that.
I am getting better battery life in ICS as compared to GB...

I have that app installed, but frankly have no idea how to use it very well. From what I can tell, it is Kik Messenger which is creating a partial wake lock (but I need that to send pictures to my friends), Juice Defender which is supposedly saving battery life and biggest partial wake lock is RILJ or something. But, that is caused from a weak signal and I get that regardless of network at my house. Besides moving, I cannot alter that. As for Juice Defender, I've heard nothing but positive reviews from it. My main aim is to get deep sleep working, but how?

first ,samsung ICS is poorly made ,second you have a high chance of bricking if you wipe your phone with their official kernels so don't do it.
third ,like others said ,juice defender (and any app of this sort) doesn't work anymore (android 2.2 and up) so just uninstall it.
fourth ,not entering deep sleep is mostly due to a rouge app ,and since wiping is not an option for you you need to hunt it down manually ,use better battery status (learn how to use it!!!) and uninstall any apps you don't need.
fifth ,get some knowledge then get rid of crappy touchwiz ROM and install CM9 ,you'll see a huge improvement in terms of performance and battery life.

Okay, well this is my first proper Android device (minus an old second-hand HTC Desire which had awful storage and I used for around one month). Secondly, I do know that other ROMs offer better performance and battery life but flashing them onto my phone is something I'm not very comfortable with and surely it would also void my warranty. I've only had the phone for four weeks and don't want it wrecked already.

I'm fairly new to android as well ,had an S2 (which was so good that I only rooted it ,no custom ROMs) for 5 months before the note and that's it.
but I rooted my note the first day I got it ,and installed a custom ROM less than a week later (was a total noob at the time but I read and learnt quickly) .
then CM9 arrived and I flashed that immediately and haven't regretted it so far.
but I had no warranty to begin with so.....
note that if there is something that can wreck your shinny new note ,then it's amsung official ICS update (read the announcement sticky on ICS and bricking) .
but how experts can explain the fact i face:
With every official and custom ROM i install, even CM9, my note keeps eating battery when in use plugged to the charger... it's unbelievable... I can't understand how it happens.
by the way: i always full wipe before installing any custom/official rom.

Well, is there nothing that I can do to trigger deep sleep or improve battery life on the stock ROM first of all? Secondly, how difficult is rooting and would that void any warranty?

it can't happen ,I'd say you either have a faulty battery\charger or there is someting wrong with the phone itself
the note charges while in use and connected to a charger.

yes you can ,uninstall the violating apps ,learn to use better battery status ,you'll find that there is an app or two responsible for the wake locks ,thus preventing the phone from entering deep sleep.
or simply install every app and game that seems suspisious or poorly made ,and just keep the essential ones.
as for rooting ,it couldn't be simpler if done carefully and to the letter :
1.flash back to GB using PC ODIN
2.root it
3.backup your EFS folder (important , very important) search for it on the forums.
4. install custom ROMs (stay away from unsafe kernels please ,read the sticky thread about ICS kernels)
3. enjoy
use this guide
http://forum.xda-developers.com/showthread.php?t=1329360
yes there is an easy way to root while on stock ICS as per to this guide ,but I prefer you stay away from official ICS for the sole reason that it's dangerous.
remeber the key is to read and read and read ,in a month you could become a pro
on the other hand if you go the lazy way ,you could just end up with a bricked phone
also once you root ,your warranty is void ,though if you're careful you can return it to stock condition and they won't tell the difference
be careful

@Brad387
I have had mine for about 2 weeks. When I turned it on and did the initial setup it had a new software update which was ICS. Since then I have been having issues with deep sleep as well. I turned stuff on and off and it has been totally random what was preventing it from going to deep sleep.
I have done this trick that has been on this forum.
Put you phone to airplane mode.
Power it off completely
Remove battery for 20 seconds or more
put battery back in and power this thing back on
then turn off airplane mode.
This seems to have helped me get into deep sleep. BUT there have been instances of rogue crap going on. Like I was using Google maps with GPS on. When I got home and was done with my traffic mapping I turned off the GPS switch and turned off my phone. I checked an hour later and the battery had died 10% since I got home which was more than when I was driving. I checked Better Battery Stats and it showed that GPS was running that whole time. So I turned on GPS again in the toggle waited a couple seconds then turned it off again and bang it went into deep sleep. It sucks that I have to check crap on it all the time and have become a bit paranoid because the GPS glitch had my phone running pretty hot. Since then everything has been running well and deep sleeping.
There are other things I did do too and the below stuff is up to you if you wish to proceed. I rooted my phone which was very easy...at least for me. http://forum.xda-developers.com/showpost.php?p=20963730&postcount=3 this is what I used with no problem.
From there you can freeze a bunch of stuff you may not use like Social Hub, Accuweather etc etc.You will need Titanium for that though and root access.
I logged out of Latitude too which was on by default for some reason.
If I remember anything else I did I will hit you back here.
Bottom line was finally yesterday I was able to get thru the entire day without needing to plug in so there is light at the end of the tunnel...I hope.
Not sure if this has been mentioned but CPU Spy lets you see if you are getting into deep sleep mode and how much time you are in it along with the other CPU mhz that its running.
Hopefully this can help out a bit because I have been in the same boat and it has been driving me mad. Sorry for all the random thoughts too...I just typed them as I remembered things.

My phone does not seem to enter Deep Sleep, but runs constantly at 200 MHz instead. At present, after turning on the built-in power saving mode (not noticing any performance differs so can't even tell what it does), running Juice Defender Ultimate on aggressive and screen filter I burn around 2% per hour if I just leave my phone locked. Is that healthy?

But, that is caused from a weak signal and I get that regardless of network at my house. Besides moving, I cannot alter that.

Actually, there is something you can do about that!
Both Vodafone and Three can supply you with a Femtocell which can greatly improved your signal at home, and uses your home broadband as backhaul.
I know, because I have them!

Battery life of my Note was horrible after upgrade to ICS, and actually already quite bad the last month on GB2.3.6 (all unrooted).
It could get quite warm and often when opening my case the screen was already on.
So I did wipe my phone, reinstalled all apps and battery life has improved immensely.
I see several warnings here about chance to brick your phone when wiping on stock ROM, but not solving the battery drain is of course no option and we don't have a guarantee from Samsung for nothing...

Well, thanks for offering that advice but how expensive are these things? Also, I'm the only person on 3 in my house so kind of a waste really...

your phone should not be running at 200MHz when you hit the sleep/power button. So if its in your pocket and the screen is off then 200MHz is not healthy. Something is running in the background. Have you tried the airplane mode battery trick yet? What I did when that was happening to me was...turn on the airplane mode, power off the phone, pull out batt for 20 secs, put batt in and power on phone, turn off airplane mode, then go to CPU Stats and clear it, then put phone back to sleep and let it sit for a half hour or less if you cant handle that wait like I couldnt. Go back to CPU Stats and and click refresh and see if it helped and if your phone went into deep sleep.

Solution for Battery Drainage in ICS Stock ROM explained

My English might be poor, hopefully this thread help. I have flashed stock ICS in my tab baseband XXLQ8. After fully recharged my battery, I found that the performance was not tolerable since in HC 3.2, it only drains 2-3% battery life per 24 hrs in a sleep mode. Unlike HC 3.2, ICS 4.0.4 (baseband XXLQ8, some addressed as Italian stock ROM) drains 1-2% per hour in sleep mode. My battery life dropped 7% in 5 hours without any usage (off screen).
Later on I installed CPU SPY and BetterBatteryStats suggested by some of the posts here. Having the same problem, my tab could barely get into the Deep Sleep state when it was in sleep mode. Instead Deep Sleep, it still works under 216 MHz.
Somebody here suggested it was the Push Service in Samsung App, Google+ or something. Some even found that it was the GSM problem. With the sim card slotted in, the problem gone. However we are pretty sure the effect of the problem is battery drainage in sleep mode. We found that there is a kernel wakelock called l3_hsic all the while running in background that prevents the tab from going into Deep Sleep.
There are several possibilities causing this to happen. Apps creating wakelock maybe, some suggested Google+ with the sync or upload function enable; hey, wait! I don’t have a Google + account signed in, could that still be the problem? Some say Samsung App Push Service causes it to happen, so I just give it a try. Launch the Samsung App, go to the Settings and disable the Push Service. Put the tab to sleep for an hour and check back. Battery drainage still occurs since it dropped 2% for an hour. What a disappointment. But wait, this time I get into the tab Settings>Application>All and find the Samsung Push Service. Checked there were permissions such as creating wakelock and prevent tablet from sleeping. Tap on it and uninstall the app. Put my tablet into sleep again.
After 3 hours, turn on the tab and check back with the battery stats. CPU SPY shows that my tab could get into Deep Sleep state. My battery life did not even drop a single percent. Today is my third day from the last charge. Thanks god, problem solved.
HIT THANKS Button if this helped you.
It doesn't work for me. Still looking
and for l2_hsic what could be the solution? i`ve searched on xda and google but i didn`t find any reliable solution. Any advice?

Is that the "battery drains while on airplane mode" issue? I have it too :crying:
it doesn't work for me bro..
for me, i noticed that google maps (auto update on my place, that friends can see where i am) Since I enable auto location my place, i get no deel sleep, when i have disable it, i have 100% deepsleep
I disabled Maps to fix my battery drainage issue. If I need to use maps I just enable it.

The solution to the l2_hsic is to insert a uSIM.
Nevertheless the deep sleep problem will remain. Sorry!
hello,
can we flash another kernel ?
I have the same issue with my galaxy tab 10.1 running Stock ICS 4.04. Something is interrupting deep sleep mode and the battery consuption is 2% per hour in standby mode.
After rebooting it seems to be OK but later and i dont know when/how/why... stops entering deep sleep. I think this problem needs a revision by Samsung but i am sure that they have forgotten us.
I've seen a firmware update on some other thread, for our tablets... but it seems we're not getting it OTA
Another Tips for slove it
I found another solution for this issue in this post:

Battery drain while sleeping

Hello
I have a samsung s4 i9500 new phone about 4 months old. I encoutered many battery problems so i installed Arrow rom, which i fell in love with it in a sec, it had everything and the battery life was just amazing. (Thanks to all who contributed into making this amazing rom).
But something happened when i installed an app about adds and it kinda restored my phone yo factory settings, i didnt care much for the reset, but i found out that my battery life ia no longer like before. Let me give you my states before and after.
Ps: i reinstalled the rom hoping better resulta but it was the same
I sleep usually at 1pm and wake up at 10. Thats 9 hours, when my phone was fine it only drained about 10% or 12%.
But as in for today for example, i slept 7 hours and it drained 20%.
Most of the draining came from android oa at 89%.
Please note that before i go to sleep i always charge my phone to 100%
Is there something wrong? Ill do any test to solve mu problem.
Thanks all

Hi.
U should install BBS app and post "other" and "partial wakelocks" screenshots so that we can tell what's eating up yr battery life.
Cheers.
deep sleep!
Yeah BBS is definitely the way to go..also you might want to check skipjack's awesome thread for better batt life when idle (insanely )
http://forum.xda-developers.com/showthread.php?t=2357417
I got better batt life with my s4 after i did some of their tips on this thread..
Sweetdreams to your phone's battery! ))
I have attached my files, btw the battery is kinda weird, one day it drained about 40% but somedays drains way less, keep in mind that when i go to sleep i turn off my wifi and use edge network, and power savor too.
Some solutions that I follow that kind of stopped severe battery drain and got the phone in deep sleep mode:
- Disable "Scanning Always Available" from Advanced settings of WiFi
- Disable GPS and 'Use Wireless Networks' from Location settings menu
- Greenify apps and a few services
- Before putting the phone down for good, clear all the recently opened apps by pressing and holding the HOME button and clearing them all. Then open up the task manager and clear RAM.
- To get the phone into deep sleep (you can monitor this using a free app called WakeLock detector, available on PlayStore), if you have the habit of switching on the screen and then switching it off whilst being in the lockscreen mode (just like you check time quickly without unlocking the device), the S4 DOES NOT go into deep sleep mode even though the screen is switched off.
To solve this, you need to unlock the screen, get to homescreen and switch off screen from there instead of directly locking/switching off the screen without unlocking the device. Yes, it's hell and I don't know why this issue persists :/
