Hello everyone, I have a problem, first of all I want to say that I disabled all synch, all google services , all wakelock works good. But I get around of 3 h. sreen usage a day( I think it's strange cuz many of n4 users get 5-6 h. of screen usage), on high CPU usage or in 3D games in 1 minute battery level may decrease around 10% , If I browse everuthing is allright, but all the games get my battery killed in a minutes. I have CM 10.1 and matrix kernel without GPU OC plus decreased volts on CPU, So my battery is bad or what? any help?
That is odd. I would suggest to flash stock kernel and stock 4.2.2 . See if that fixes the problem.
3 hours of screen time is average. 5 to 6 would be Highly unusual.

I've flashed 4.2.2 stock rom, now get lower score in antutu (around 17k) I tested rom that way: for 100% cpu and gpu load I played 2 h. in real racing 3 and 1 h. of benchmarks. So I have such a results, what you think is it normal or not?
forgot to say about 100% brightness
Odp: Terrible battery drain on high CPU usage
That's pretty strange. When I flash CM10.1 my antutu score was low. Also when I flash on CM10.1 faux kernel I got multiple crashes so I revert back to stock with enhanced faux kernel. Battery is average and about 17000 score in antutu on stock CPU settings. I think CM work correct with CM stock kernel. In my other phone SGR CM10.1 is super stable.

On CM 10.1 I get about 19k score with matrix kernel 21k result. But when I load cpu&gpu to 100% with games or navigation battery level may instantly decrease by 10%, u can see in 3rd sreen (1st post). Battery discharging schedule is not smooth, I've never seen before such a problem on other android phones. By the way, on stock temp. on full load was around 43 C. on CM 10.1 and matrix was around 49 C.
Also asking for help. Is the battery of Nexus 4 so bad? I am using the stock kernel. And i dropped 3% in half hour without doing anything.

now I'am on stok 4.2.2 with franco kernel... results are below, is it normal for nexus 4? ow my bettery is weak? I thinks most of N4 owners suffer from big battery drain

At 100% brightness, and playing a graphics heavy game. I'd say you're perfectly fine.

One day on battery is pretty damn good
That is normal if you are on 100% brightness
I don't play games and have my brightness set at 25% for normal use and the phone lasts for 2 days at least...
Last night I went to sleep with 42% battery and woke up today with 38%
Not too shabby... but I just got the phone 3 days ago, so will see how it reacts after a few cycles...
I'm on XenonHD 6.0 with Faux kernel (it's the one they integrated in the ROM)
Hope that helps!
Hi, i only recently installed the latest rootbox nightly and m-kernel a56, and i'm registering a huge battery drain (i came from stock rooted 4.1.2). I gave the device a few days to settle in the rom/kernel, but the battery drain's the same, so i installed setcpu and set about undervolting. Can you tell me some recommended or usual undervolt settings for best battery or best battery/performance ratio ?
Hi,
My battery life is not that good so I installed Perseus kernel with Synapse. What can I do to improve my battery life? I didnt notice diffrences when reducing Cpu clock speeds. Thx
Im on Omega Rom.

Hi
Mate , first thing you have to do is find out who is running wild in your phone use BBS
http://forum.xda-developers.com/showthread.php?t=1179809
Let it run for a few hours and read the log to find out what is keeping awake the phone
Also review your settings , wifi , mail , FB , location.....
Hi as my point is my temperatures are really rising as I play sanandreas to 90°c is this hardware issue or battery problem as I had not changed the battery as far aa I know.. At now am using ressurection ROM 4.4.2 3.3-49kernel Perseus alpha 19 as my idle temperature is 51-55 is my idle temp normal? Or any hardware issue or battery problems?
Thats normal. When playing game, cpu will always run 1.2ghz-1.4ghz and sometime run 1.6ghz. U should undervoltage for overheat problem. Playing game reach to 80-82c (better than stock voltage settings). Now im using volt 15 (voltage settings in battery profile) and ale95 rom.

Wrong place mate. It's Development section. If you want to ask anything, then create a thread in Q&A section.
And regarding your problem, that's normal. Our chipset throttling more than another chipset while doing a heavy job. Also that's normal temp while idle.
Moreover, you're using AOSP ROM. This ROM made device work hardly for performance compared to TouchWiz.

I am experiencing severe battery problems. Attached screenshots is "as good as it gets" in terms of battery life for me. That's with Greenify and Amplify doing their thing.
This is 3 hours of SOT a far cry from what you guys are getting.
910W8 on DPK1, stock ROM, with a the Beastmode r56 kernel. Underclocked and undervolted, with the interactive scheduler. I have tried just stock Kernel settings as well.
Flash to stock doesn't help. Brand new Anker battery.
Any ideas?
