OK, my wife has had this phone since last September and it has just recently been suffering from some very unusual battery drain. Tonight I placed a fully charged battery in it at 9:30 pm killed all the non essential apps via menu / settings / running services. And by 11:00 it was already at 50%. What could be causing this issue? It is fully stocked and not rooted. Thanks for the help

Possibly a app that u downloaded is waking it up or an update u did recently.

I'm having similar battery drain problems with my SGS2. My phone shuts down, like empty battery power, when I'm online for a few minutes or playing a game when in fact the battery still has more than 50% stored power. This started happening a few weeks ago. I didn't download or update any app before I noticed this "phenomenon".
Anyone has an idea what could be causing this battery drain? How can I resolve this?

Thee have been a few times where my battery drained overnight where it only usually goes down like 5-6%. Both times I run found out there was either a tower down nearby or they were doing work. Check an app like badass battery moniter, it gives you a rundown of apps and modem drain.

Download system panel and see what programs are eating up CPU and using data. Also consider Wi-Fi and data toggles they save a ton of battery and turning off background data. If your still have major drain issues hope got insurance...bring it down and get a new battery.

I know this has probably been answered somewhere before but I couldn't find a good answer. I have lost 10% battery in an hour and a half with no use other than stand by. Any tweaks within the Cyanogen settings I can make to help at all?

Did you add any kind of task killer on your phone to prevent things from running in the background all the time?
I have advanced task killer but its just an app. Its not running all the time.

And I let my battery drain all the way to 0 and charged fully from scratch with it off. It lost about 20 in an hour add opposed to 10 today.

You can set it to auto-kill. I'm actually kinda surprised you're having a lot of battery problems with RC3 though, you may just need to wait a few days for everything to stable out. When we get new ROMs we like to play with them a lot and drain the battery! I would also suggest using auto-brightness to prevent excessive screen power usage.

That's not normal for idle at all. Is the battery old and just wearing out? if it's fairly fresh (< 1 year) then it should be fine. Try betterbattery stats to see if the phone is keeping wakelocks and also CPU spy will let you know if your phone is reaching the deep sleep state.
I have the brightness not on auto because it was picking up the light right, but it's turned down pretty low. I'm about to post the results of the battery info, and those 2 apps... They're in the below zip folder...
I unplugged my phone about a half hour ago and have been using it a decent amount. Went from 100 to 80 in that time.

Battery doesn't show what apps are running
All my battery displays is Screen,Device Idle, and Wifi
It shows no other third party app that is running. This can only be temporarily fixed by rebooting my Note 2. Which then it happens again after full charging the device.
Is there a fix to this? I barely got it and it is bugging the crap out of me
Same here thought it was so weird

is this something worthy of replacing? still haven't fixed yet.

This happen to mine too.. when i turn off auto sync in Settings>Data Usage>Left menu then turn off Auto sync data.. But good in battery saving..
My Note 2 just started doing this as well. Settings> Battery and all it shows is the overall usage graph and Android OS 100%. If I click on Android OS it shows 298 days of usage. I tried deleting the batterystats.bin file/full charge/reboot etc but that didn't work.
Anyone have any ideas?

Fixed it.
Ran it down until it turned off/died.
Plugged in stock charger.
Once fully charged..green LED...powered on.
Booted into CWM from restart menu.
Wiped both caches.
Wiped battery stats.
Reboot.
Unplug from charger while at 100%.
Thought I followed these steps before but apparently I didn't.
Back to normal.

My note was draining battery like crazy even on power saver mode, it would drain like 10% during night on power saver.
I did a factory reset it seemed to fix it for a day and then now it is draining again fast, I have all power consuming things shut off I don't know what else to do.
If there is one more tip for this would be really useful.

Some application is messing. Depends how many you have installed, try disabling them and then run each one by one...

That's a good start, 10% on power saver could be a lot on a phone with no apps, but if you have lots of apps its not that much, even on power saver some aps may be accesing the network, if you are connected to a wifi that would eat some battery as well.
If you added no apps and this happens then it could be a bad battery, unlikely but stuff like that happens.

Remember to sign out of apps like Google+, YouTube and Facebook, if you are signed in. If I notice quick battery drain, I'm often still signed in.
I dont know if the battery is bad or im missing something that is draining it

Is there a way to know if I have a bad battery please? I'm really concerned.

Unfortunately, I believe the only way you'd be able to really measure the mAh of your battery would be to compare with another of the same.
Can you post a screenshot of your battery usage?
Might help us narrow it down a little. Sounds like a wake lock but could also be due to terrible cell reception
Sent from my GT-N7100 using xda premium
Do you know your device and android fairly well? I am guessing its a combination of the above stated bad reception and your os & apps update schedule. There is alot of way to save power by going through and changing your notifications and app updates, as well as various settings on the os (ex. Switching to airplane mode @ night or at least turning off your data) so that your facebook isnt uselessly refreshing at 2:18am to see what club steve is at while your sawing logs.

Hi everyone, I'm new here and signed up to see if anyone could shed some light on an issue I'm having with my rogers samsung Galaxy s3 white 16gb i747m.
I contacted samsung because the device is only several months old and they want to send it for analysis. But I'd like to see if anyone here is familiar with the issue.
Anyway on certain occasions when the phone is left u plugged at night and fully charged it will be depleted to 1% in the morning.
When I checked the battery information it shows the Wifi and wake are on continuously through the night. I don't have any apps like Facebook or anything major running in the background. I took a screen shot of the battery screen when it happened once.
When I explained it to Samsung they told me to turn off all my processes before going to sleep using task manager.
Any other ideas?
Thanks!

I've had battery issues ever since I bought my Note 2. I tried buying a new battery, custom ROM (ARHD 13.0), custom kernel (RedPill). I get a drain of 2% per hour in standby, and 17.2 percent (!) per hour in normal usage, not even heavy gaming. The screenshots are for continuous usage. I got rid of wakelocks, the AudioOut2 one by Viber, the NetworkStatusMonitor through maps. (these were 80% of all partial wakelocks)
I usually have sync enabled, 4 email accounts for once in four hours, and Facebook, and Samsung backup. That's it. I'm on an EDGE network, with network set to GSM only, WiFi only on when required.
I have ~83% Deep Sleep when I don't touch the phone overnight.
All motions/smart *s are disabled.
I don't know what else to do. My wakelocks show completely normal values. (I'll upload some when I get to unused time)

Almost 90% sleep. But still draining 10% in 10 hours of no use.
Could someone help me debug this drain?
Sent from my GT-N7100 using xda premium
If you are complaining about 10% drain over 10 hours (1% drain an hour) then you are very mistaken about how a mobile phone works.
There's nothing wrong here I can see.
I've seen people report less than 3% drain overnight. And 2-3% per hour of use. 17% an hour? Too much.
Edit: I know cell phones consume battery because they're wirelessly connected to and monitoring networks and that they need battery to receive and process packets of data and other stuff while not being used, if that's what you mean.

Is your wifi power save mode on or off?
!!
I have the same excact problem. Just bought it and the battery drains so faaaaaaaaast !!!...
The screenshots in my first and second posts are with WiFi on, connected but never searching. In the third post, WiFi was off the whole time.
Edit: Power saving was off both times. There's a noticeable FPS drop with power saving that I hate.

Please get Better Battery Stats, and post your screenshots over at least an hour of no use, and 30 minutes of use. I might be able to help. (I'll try, anyway).

Are you on an AOSP/AOKP/CM based ROM? I understand that battery will be significantly better on those than a Sammy based ROM because of Sammy bloatware, but I'm unwilling to lose all the perks. Although the figures I said people have are all for people on either stock with custom kernel, ARHD, or ARHD with a custom kernel.
Edit: I also took care to take these figures from this forum from people who had a few syncs/online services enabled.

Install perseis kernel...dont try to install cheap apps or games from playstore...beacause they run even after closing it in the background...try to deactivate your 3g network and wlan ...btw.. try tge app 3g manager...it deactivates your 3g mobile network when you lock the phone.. and reactivate it when you unlock the phone..it might help you.

Not anymore. Perseus kernel with Greenifier = 0.3% drain an hour, and 5% per hour of use.
