I bought this phone last week. And it worked fine for a few days but a couple of days ago I charged it to 99% before sleeping and then took it off the charger. When I woke up after 7 hours, it was at 51% battery. I restarted the phone and it worked fine. Then last night I again charged it to 99% and removed it from the charger before sleeping. When I woke up, it was at 70% after 4 hours of sleep.
A lot of the battery is being used by 'Android OS'.
Right now my battery is at 26% after being used for about 8 hours of average use.
31% battery usage is by Android OS. It has used CPU for 50m 16s.
Display has been kept on minimum brightness and used for 3h 14m and used 23% of the spent battery.
My problem is with the Android OS thing. What is using so much of the CPU? My friend's S2's Android OS had used the CPU only for 27m after 12 hours.
Maybe you could ask yourself, waht did you do just before the problem started.
Maybe:
- More syncing eg. email account?
- Power saving functions on/off?
Or any else strange behavior of android
I did install Whatsapp before the first time it happened. But removed it before second time.
Even hard reset my phone today.
Let's see what happens tomorrow morning.

Maybe u wanna include details like
1) wifi on/off periods
2) data on/off periods
3) overclocking
4) back ground processes/programs that are continuous running
5) Rom version
I dun have any data plans nor do i use wifi.
Calls less than 30mins in total. less than 50 SMS.
No games. No overclock.
My phone lasts more than 2 days !
As I said it was an average usage.
About 20 minutes of phone calls. Some messaging. No internet (wifi or date)
I am still running the stock firmware so no overclock.
I slept for about four and a half hours and the battery barely shifted from 100 to 99 tonight. But the 'Android OS' has used the CPU for 15 minutes in this duration.
Can somebody tell me the stats of the CPU usage by this process on their Galaxy R?

Battery usage
Some information:
- Overclocked at 1.35 Ghz (ardatdat's kernel)
- Wifi ALWAYS ON
- DATA ALWAYS ON (for whatsapp)
- Only 2G (GPRS/GSM mode)
- Average user (1 month about 15 min call and 100 SMS) but 500 +/- whatsapp
- No push mail but check it twice a day
-Automatic display brightness
Battery Usage:
1D 0h 54m
Android OS - 27% (52m 21s)
Display - 18%
Android System 13 %
Music 8 %
Mediaserver - 7 %
Internet - 6%
And quite many below 5 % like Market and Phone idle.
flick your 3G connection to 2G/GSM and make it as default in Setting->Wireless-> Mobile networks. You may notice a big difference.
BTW, I notice with ardatdat's new kernel my phone battery actually last longer than a fully stock 2.3.6 KK5. I think I m flashing back to ardatdat's
In the stats that you posted, you say that your battery time is 1d 54m. Is that on a single charge?
Have you noticed any battery backup improvement after rooting? I had thought of not rooting it till a custom ROM is available but I'll do it if it helps my battery life.

Yes, that's on a single charge. I haven't notice a big difference of battery life between the stock kernel and ardatdat's kernel unless the performance
1. There is a problem after wi-fi on/off on some 2.3.4 ROMs (at least russian one)
how to check the problem:
turn wi-fi on, turn wi-fi off (not sure if you should done establishing connection to interent)
then put phone on stand by
check if it consumed about 30% of battery after 8 hours of sleep (normally 2-4%)
2. Also there is kernel related problem
Since it upgraded to 2.6.36 there is issue - too much kworker/u processes started when device goes sleep and wakes up several times.
So, install root, advanced task kill or terminal emulator and kill those processes (as well as some other)
Turn off background synchronization, e-mails, social hubs and other internet related applications if not needed.
My current battery status: 63%, since 2 days 9 hours abd 14 mins of use
How can I check my Kernel?
Sorry for the noob question. New to android.

There is string like this:
Kernel version
2.6.36.3-I9103...
But don't bother... We should have all 2.6.36 kernel by default
Thanks.
Flashed ardatdat's kernel. Rooted now. Will be monitoring battery and freeze whatever bloatware puts too much stress on the battery.

I have the same wifi problem on swedish 2.3.4 rom, even after turning of wifi it draws a lot of power, only reboot helps.
If i reboot after using wifi, and dont start it again the battery last for several days with moderate use.
Does the root/kernel change correct that wifi issue?

Will get back to you with that, but currently it seems that either the answer is yes or the 'bug' hasn't hit yet cause even after switching wifi off, the battery backup went back to what it should be, though I haven't had a lot of standby time. Will take it off the charger before sleeping and get final results tomorrow.
Battery issue
Hi.
I got the same problem, on stock rom. Fully charged before going too sleep, 60% battery when i wake up in the morning. Standby mode, 3G and WiFi off. I searched the net and found somethig about the sd-card, dont remenber the site. I removed my sd card (16 GB class4 SanDisk micro-sd), (slot is free) and now it drains about 1% over night instead of 40%. Before it last 1 day with average use, now it last 4 days. I hope sw uppgrade will fix the problem.
Regards
Finnbeck
Running InfectedROM V1 on ardatdat's kernel. Amazing bettery life. Lasted 12 hours with about 2 hours of music, an hour of calls, an hour of internet browsing over wifi and frequent texting over the entire 12 hours.

I've noticed that the battery life of eos3 isn't even close to what I got with eos2. also, i've noticed that, even with my tablet sitting idle, the android OS process is at the top of the battery list whereas the tablet idle process is number 3 or 4.
is this just a symptom of nightlies? or is this a jb issue? or am I doing something wrong?
note: i performed a full wipe, clean install of nightly 144
It depends, my XOOM on EOS JB can last a whole week easily with Wi-Fi on and moderate usage.
hi guys, i've been testing ICS and JB roms... all of them are awesome... but there's something that that intrigues me. Why those roms drains the battery so fast? the only thing that i could imagine is that migth be kernel related... what's your opinion about it?
Previous ICS versions were not much battery hungry but last version which incorporated OMX libs is a battery killer, even if used without Gapps. Too much wakelocks!
you're right

mmm that has more sense for me :silly:
well, we should wait for optimizations...
I dont know about others, but for me the performance and battery of cm9 by hephappy is like the stock gb rom. and that is maybe bcoz i dont overclock my phone.
while using the above mentioned rom i used wifi for over 2 hours (just browsing and saw few vids about 10 minutes on youtube) then after turning off wifi i just checked text messages after every 5-6 hours and battery lasted for day and half.
Running ics on p500 is somewhat similar to running windows 7 on PIII pc. ;P
ICS is not more battery hungry. I get the same performance as I do on GB. The problem here is the way your device is set up and the software you use on it. Screen brightness plays a big role on our devices. So does anything which uses data, specially through the cell radio. I use wifi, whatsapp and still get a full day service out of my little P500 on ICS.
When I look under settings > battery, I find that it is the display that drains the battery so fast.
It is gapps which drain the battery.. also the screen backlight
That could be related with hardware acceleration which is one of the key events started from android 4.0, and if we have 3 buffers working on jb now there will be MORE battery drain.

That maybe one of the reason since battery drains more when screen is on. When phone sleeps, battery drain of ics and gb is nearly same....
EDIT: The 27th Nightly fixed Wifi and battery issues.
Sorry if wrong area, I can't post in the development forum yet.
Specs: SGH-T699
OS: 4.4.2
Kernel: 3.4.77-cyanogenmod-g33b0384 [email protected] #1 Sat Jan. 25 22:19:49 PST 2014
CPU: ARMv7 Processor rev 4 (v71)
Problems: Wifi can't be turned off from pull down bar, but can be switched to off in settings. This does not stop wifi though. Airplane mode doesn't stop it either. Internet turns off even with the WiFi on until reboot. Overnight with a charged battery Wifi (while system is unplugged and the screen is off) takes up about 40% of battery. Stock can last 6-12 hours depending on use, while CM10.2 Stable can last 6-9 hours depending on use. This build lasts maybe 3-4 hours without use (when screen is off), and 1-2 hours with light use.
I had the same problem, but everything works fine in 27 nightly

Thanks. Do you guys get anything near CM 10.2 in terms of battery life?

Yea on the 27th nightly (haven't tried the newest one) I got better performance from phone, and less power consumption on the battery (that is running music, browsing, and texting) I am at 6 hours with moderate usage and still 77 percent battery.
So My OPO Runs Lollipop for the last three months, and battery life was never great.
I've heard that kernels can fix it and give me 8-10 hours screen on time.
flashed franco, metallized, tyr, tgm and changed the profiles with kernel auditor but it just doesn't do anything except make the phone run slower.
does anyone have this issue too?
P.S
I'm currently running cm12.1 nightly and metallized Nev8 and struggle to get 4 hours SOT

Same here, exodus made it a little better. My average screen usage is 4hours then the battery is a nearly zero (having lg watch r always connected to the phone)
Tried BlissPop, CM unoffical by jgcap, cm12 nightly, all result in the same. I also switched from chrome to opera to reduce battery usage, it gives me ~30min more screen on time.
Since I'm playing Hearthstone the battery life is 19-20hours, because Hearthstone drains so much.
