Currently, my nexus 6 has its boot loader unlocked and it's also rooted. It's currently running on the latest Cm12 nightly & franco.kernel. I get about 4 hours of screen on time. What are some tweaks that I can make to improve battery life? Any suggestioms will be welcomed, such as kernel settings, any flashable files, apps, etc. Thank you.:victory:
I just realized I posted in the wrong section, sorry about that.
questions go into q&a, not the general section.
edit.. mod moved the thread to q&a. go on as you would normally..
Its always worth analysing wakelocks. Location for example wakes up the phone a lot. The more frequent a phone wakes, the less deep sleep it gets

Hi,
I have a SGN and CM10 nightly, and updating daily.
The only bad thing for me in this JB based ROM is the heat and the battery drain (almost can see the energy flying away the battery )
As I have been reading a little bit, I think, and please correct me if I'm wrong, that the KERNEL can change some equipment behavior...
Question:
Do I have to stay with the kernel of the nightlys?
If not, what options do I have, and what are the main differences between them?
If I change it, do I have to re-flash it every time I update to the new nightly?
According to your help... I'LL BE BACK!!!!
Thanks a lot

The new cm10 kernel uses updated Mali display drivers. Currently there are no alternative kernels with these drivers so you're stuck with the stock one.

I guess you have a rogue app misbehaving. I can clearly remember when I had this problem as well: battery drain and heat.
You might install the following 2 apps, to see whether your device enters deep sleep, if you already haven't.
- better battery stats (1.11)
http://forum.xda-developers.com/showthread.php?p=15869868 and
- CPUSpy (0.5.19 beta)

Then, after you checked "deep sleep or not?", you could go to this thread concerning wake locks&battery life, a very informative thread by ahalford - and he is being very helpful!

Hi mates, i recently root my HTC ONE and installed both Android Revolution HD with Sense, and also ElementalX kernel.
I do it in that order, then I reboot but...
Battery drops 1% every 10 minutes without usage...
¿Can you please help me?
I'm new in the forum but I have a rooted Moto Xoom, so I now what I am doing, but not what I am doing wrong...
Sorry for my English.
I have just use BatteryCalibration (when I was 100%) but nothing seems to change.
I also tried, right now, with Power Guard, but I am not sure it does anything....
I wait for some answers, please be explicative if you can.
Thanks a lot, nice to meet you all.
install better battery stats. that'll point you in the right direction in trying to figure out what's eating your battery up.
greenify is really good at reducing battery use, but batteryguru is really useful once it has finished its learning phase. Also, have you got the latest firmware installed for the rom?
It is the last version. The 30.
I am going to install BetterBateryStats. Whats next?
I think installing the ROM with low battery can be an issue. Can it help to reinstall ROM?
Ido not know if matters, but Sense 5 mods are not working even restarting.
.thanks in advance, i will wait for answers
I have some new information.
Battery drains a little slower, but when I entered Camera app, it does not appear Zoe option, although it is the native application.
I must say that I have flashed my rom through the recovery mode, not fastboot. ¿It is needed?
Search the thread for this, as it is mentioned in there. Also mentions possible fixes and causes.

I think installing custom kernel kills zoe.

same problem battery drain
i also have the same problem
my battery drains like 2% every 5 minutes although it is in sleep, screen locked.
i don't know what is draining my battery like this bad.
Try to disable Google Now "search" features.
Then Go to settings --> power --> disable "fast boot"
reboot phone properly using menu
Check battery drain. Note 100-98% goes fast then slows down
Enable google now search.
Issues With DEEP SLEEP
Hi everyone,
Only got one problem, the phone wont go into deep sleep mode. its stuck at the the lowest frquency with screen off. i'll explain further. when i first clean flashed the rom, eveything was good and it slept like a baby, then i went into performance settings and omni settings, i changed the governor to elementalX ( checked the apply at boot option ) once i restarted my phone, it would not go into deep sleep mode again..this isnt just this rom, its with every AOSP rom that i am testing out. Any insight, please do share.
The rom i was on when i wrote the above statememt was CM-REMIX
Thanks for the Help.
PS: i did look into wakelocks, and it seems that *alarm* in the android system seems to be the culprit.
Anyone??
if anyone else is having this issue, i've found a somewhat solution. Seems that when you diable NFC and restart your phone it wont go into deep sleep, but when you enable it and restart the phone, the deep sleep function works great...
i find it odd why i cannot diable nfc without loosing deep sleep functionality
Cm based ROMs are still not completely stable. I have experienced random battery drain and lack of deep sleep on a few builds of many different AOSP ROMs. They are still in Alpha or Beta for the most part. Give them some time they will get all of the kinks worked out.

I hope they do because i love the minimalistic approach of AOSP...
Whats CM rom are you using? how about battery life?
The only one to tell why ur phone won't deep sleep is you. Have to do homework yourself. Wake lock detector, better battery stats, those are good apps to start with then u will see what is going on.

Thanks guys for your help..its strictly related to NFC...i believe CM will eventually fix it
3 main issues exist in all custom roms whether oreo or nougat.
1. Battery drain in standby is high even in airplane mode. No drain in stock rom overnight.
2. Battery consumption is very high while locking gps. 1400ma vs 300ma in stock oos.
3. Ola cabs app doesnt work when using microg. Some libs missing in roms vs stock.
Please fix these issues otherwise the rom becomes less useable.

Let's make a thread to report the issues related to idle drain on custom ROMs. I have made this thread so that people can discuss issues related to battery life and help each other solve it. This is in no way to defame anyone. It's just a thread for discussion. I decided to make this thread because my device was active for most of the time. Very very less deep sleep
Well for some reference i flashed a rom and just magisk and fk kernel manager to track deep sleep. I was shocked to see that device wasn't sleeping well and awake for 80% or more of the time. It was without any 3rd party apps installed on ROM.
Just flashed ROM only and no verity zip. Didn't flash gaps as it was already built in. After doing the first boot and set-up. I flashed magisk and installed only 2 apps. Better battery stats and fk kernel manager to track the drain. So i guess I'm not doing anything wrong. Because i didn't restore any app or app data. I used to restore only back-up of apps using titanium backup. I never restore data. People always blame users that they used bad apps but without apps installed i assumed i could get better sleep. But it wasn't the case. Now I'm back to OOS and will update to you guys after a new update comes.
Another battery life thread? There's one since 2017: https://forum.xda-developers.com/oneplus-5/how-to/op5-battery-life-thread-t3624705
