Battery draining over night after a full charge - Galaxy S II Q&A, Help & Troubleshooting

Hi all, just been having a problem with my battery draining right down after a full charge at night, then in morning the phone is dead ..i always make sure there's no apps running in background by using the Active applications monitor, i don't use any of the Task Killer apps.. i can't understand how this is happening over night after a full charge and there's no use of the phone coz i'm in bed ...its happened three nights in a row now..
Any help on this is much appreciated...thanks :crying:

Can you install CPUSpy app? And post a screen shot of the result it seems that your phone is not going to deep sleep.

Hi, ummm how do i do that? not very technical i'm afraid lol.. it never used to do this drain right down to the point my phone is dead in morning

Download the CPU spy app from the play store. Let your phone run for about a day or so and then check the CPU spy app. It'll show you the various speeds at which your CPU has been running and for how long it stayed at each state (speed)

My battery is draining fast?

Hey guys for some reason my battery is being hammered, I've got trillian running cus I like to be signed in all times but I'm using battery saver mode and push to email
I have launcher pro widgets on half hour refresh I've amended that to 1hr and plume every half hour.
Screen is on automatic and im using gmail for email
At work I had 98% didn't use it % (in my pocket) 2 hours later I'm on 69%?
Is it trillian hammering me? I used to love being signed in all the time on blackberry so would like a similar solution
Thanks

check the battery saving mode under the settings on trillian.
I think there were some apps that were running. You can go tothe navigation: setting/application/battery use to see them. The another way, you try factory data to clean everything which you installed.
In the other hand, new battery is unstable. It needs about 2 weeks
Good luck

Look at your battery stats.. Sounds like something is keeping the phone awake.
As a general rule the phone should only very rarely be "awake" when the screen is off.. If it's on alot then start trying to troubleshoot the various apps.. Although trillian is definitely where i would start.
Yeah id say it be trillian, its a battery drainer program as its uses constant internet connection
I'm still calibrating my battery (it's been on 0% for half an hour and it's still hanging on for dear life with the screen on constantly!) but I have trillion so I'll check it out on next charge

[Q] Tab won't stay asleep

My Tab won't stay asleep. It randomly wakes up for a few seconds (5-10) then goes back to sleep. I can't seem to pin down a rhyme or reason as it doesn't always happen, but it does happen often. My main concern is battery drain. I'm running Task 14 with a boosted theme and stock kernel. I've reflashed the Rom but the issue still exists. Does anybody have any suggestions on what I can try?
Your Not Alone!!
I would like to know also, as I have spotted mine do this too on occasions, anyone got any ideas out there please?
BTW, I am also running a Boosted themed Task14 with Pershoots kernel
I am not sure in this case, but I guess it could be an app you have installed. You should monitor with task manager which tasks are running and switch them off temporary to find out which app cause the problem.

I put both cpu spy and b.b.s. along with watchdog on, and can't seem to spot anything weird. Nothing is hogging a lot of juice, and it has plenty of deep sleep time. When it does a random wake up and I use the TouchWiz task manager it shows no active apps and Watchdog only shows minor things in the background, I'm not familiar with b.b.s. or cpu spy, is there something I should be looking for I am missing? Thanks for trying to help me figure this out.

Thanks for the tip. Yeah I use b00sted's ICS theme. I noticed the other person in this thread with the same problem is also using one of his themes which points in that direction except that I believe they are pretty widely used and tested themes. However I will probably remove it when I get around to reflashing the ROM as I think that's the only way to remove it to see if that solves the issue.
In case anyone was wondering, I think I got the problem figured out. I use the honeybar app to bide my task bar. When I disable it, I no longer see the problem. (it's been a couple of days and I haven't caught it lighting up yet.)

Help:Android OS is causing much battery Drain...

I have Samsung Galaxy S2 with ICS 4.0.3.
From many days, Android OS is causing too much battery drain.
Nothing is running and even then battery is discharging rapidly.
Before that, I used to enjoy 40-48 hours of battery at normal use(only calls & sms).
The screenshot is attatched as a proof...
Please somebody help..
And please forgive me if a thread on this topic already exists, coz I've short time and I m really worried about it.

Download BetterBatteryStats from here (there is a thread), and charge your phone fully, choose kernel wakelocks and when phone is unplugged. When the phone has filly discharged, look at what is causing wakelocks (preventing phone from going into deep sleep). Look up wakelocks on Google and solve problems.

first of all, i dont think that this i anyhow abnormal - since you are using sammy rom, 15% for almost 8 hours gives you 48 hours time between charging.
in settings/battery you should tap the field with uptime, and you will get info about battery discharging - if there are blue bars showing that device is awake, but screen is off, you are probably experiencing wakelocks; then you should either uninstall recently installed app which could wake your phone, or install betterbatterystats and check what is causing wakelocks.

yeah, thats the one. compare "awake" and "screen on" blue vertical lines, every time there is line at awake but screen is off, you have a wakelock (event that wakes up device from deepsleep and causes battery drain).
as i can see there are 5-6 short wakelocks which arent too important. you would have best battery life if you choose not to use sammy roms, but its a different story.

there is no easy solutions... but if you want to get deeper into system tweaking, you must read a lot, root your phone and use different kernels to see which one suits your needs best. i could suggest you resurrection remix rom v2.6.1 as one of the most developed ics roms, since jelly bean roms are still in pre-release stage. also a dorimanx kernel, because its most supported. using above combo, i have great deepsleep with almost 0 wakelocks, and about 5 hours of screen time with heavy usage (opera browser almost all the time, and opera is very cpu intensive browser). battery drain while screen is off is almost obsolete.

you can try to clear battery stats after charging your battery to 100%, maybe it will help, but my opinion is most xperias have poor battery performance. I tried to do a lot of things but nothing worked.

Well I saw tht your WiFi was On almost continuously... Turn it off when you dont need it... WiFi is one of the main reason for battery drain... And if you can't do it manually then install some battery saving app like juice defender wich will turn off WiFi when not in use...
My phone runs almost 1 day with moderate use of WiFi, tht is turning on only when needed else off... If I keep it on always my phone runs out of battery within 8-10 hrs.

No matter if your phone is in deep sleep or not... If your WiFi is on even in deep sleep it will still drain the battery... So try with WiFi off 1st..
N the thing with battery stats after restarting thing...
Download battery calibration from play store n calibrate it when you r charged 100% that will hopefully solve the stats problem... But battery calibrator needs root.

ohk ohk ill try batery caliberator and tell u the results
Battery calibration is not needed, it wont do anything - everytime you charge your phone and unplug it android system makes new battery stats.
WiFi is may be drainig cause look at the blue line after WiFi - it doesn let the phone fully sleeps. So try turning it off (android percentage is very high too, may because of WiFi)

Well that happened coz before there were some apps running in the background so it gave you backup of 16hrs but after the reboot those apps were killed n maybe you didn't open those certain apps after reboot and thts how u got more backup...
So do one thing, download 'auto memory manger ' from play store, its red color icon with tools On it... It kills all the unnecessary apps running in the background draining your battery... On the first start it will guide you through On how to set it up according to your needs.. Try it... Works gud.

From the screenshots, I noticed that your cell phone wasn't receiving signals throughout the deep sleep mode. If the phone isn't receiving signals, or is receiving low signals (1 bar), the phone automatically puts more battery juice into the radio transceiver to catch better reception.
Its possible that your phone has been expending its battery throughout the night to catch better reception - try putting it in a better place with more reception during the night, or in Airplane mode in case reception during the night isn't vital/important for you.

Nobody can say without having any information.
Biggest reasons it'd have are:
1. Bad connection, your phone is search for good signal all the time and thus draining battery.
2. One or more of ur apps interrupt deep sleep of ur phone and let it drain battery.
If bad signal is the cause the only thing u can try is flashing another modem. Otherwise a new provider is needed.
If apps are the problem, you'd get greenify and hibernate all apps u don't need to push notifications.
If this problem still persist, download betterbatterystats and check which app or process is stopping deep sleep of your phone.
I don't think I have to mention GPS,wifi,bluetooth and automatic sync should be deactivated right?

You could also use greenify to close any apps that are still running when your screen is off. Also, you could try using a different kernel such as dorimanx or apolo.
