There's no such thing as 'a good rom for battery'. Because everyone uses their phone differently & everyone has their phone setup differently. Try a bunch of roms/kernels out until you find a combination that gives you the battery life you're after. Also, there are hundreds of threads on here with lots of info/tips on how to improve battery life - search for them.

Hey Tony! :angel:
OP: all I have to add here is that the Android OS battery drain issue is well-know (a quick search will yield a tonne of threads), so no point elaborating on that. What I can recommend though is downloading BetterBatteryStats, and check for any kernel wakelocks. Fix those if they're there; I will not explain how to, as there are already many threads on the topic. Those will be the main source of your battery drain.

thank you!
yes i found tons of topics about this subject,but not really solution,
in my case when i kill all apps WIFI still working(see that on the wifi icon on top bar)with my old Galaxy s1 that's never happened.
talking about BetterBatteryStats ,i found that Maps and GPS drain some battery but not too much but i disabled GPS and Google places service i won some battery life but the Android OS still killing my battery.
by the way have you this problem to?
thank you.

Maybe "One Power Guard" can help you downloaded from http://forum.xda-developers.com/showthread.php?t=1889740 Then feedback me you use effects

I don't really get it. So you're getting 23 hours but 81% Android OS. Did you only showed black pixels or what? Even at lowest I don't get that.
BTW, you can take screenshots by pressing home + power button. No need for third party apps .
So instead of having a look at the threads on this forums you made a thread for yourself? Smart.
There's already a massive thread on this topic.

Its just show that, as a matter of fact .. if i browsed the net or played with any app it will drain within 90 minutes.
and thanks for the screen-capture tip,
There seems to be a bug with KE2 on the SG2.
But Im not sure how long the battery lasts then and how it looks like. But it could be that

You dont need to do a search, it's been on the first page of the general forums for the last two weeks so you don't need to do a search just use your eyes.
I can sympathies with your situation because I have same problem, but please read through the threads made before making comments.
there are always some trolls around....

[Q] Why does my phone turn itself off at night?

I am on ICS XXLPQ rooted and since the beginning of the week, my phone has turned itself off during the night and thus my alarm doesn't go off. I've noticed some weird battery activity so I PowerDefrosted all my frozen apps to see if it fixes the issue.
I did accidentally flash a stock ICS over my Three branded one. Could this be the issue? Cos right now I'm considering a revert to GB as ICS is nothing but problems so far.
If someone can help it would be greatly appreciated. Thanks.
Here's the odd activity in picture form;

well looking at your wake time it looks like your phone isn't going into sleep mode much overnight.
Check the apps list and see what app is using the most awake time.
I'm currently using a three branded ICS which I manually removed all the bloat from and my battery life is ok.
No ideas. The only thing using the most power is my display, but that's normal. Is there an app or a way to find out in more detail at all?
Cheers.
And my bloat is cleared, but only the ones I definitely know are safe.

Many people have encountered massive battery drains and random reboots on Sammy ICS.
Id suggest downgrading to GB or switching to some custom ICS rom as clearly sammy did a ver ****ty job.
If you want to moniter stuff try Ram manager pro....It keeps ur apps in control and id suggest juice defender also.
If it happens tonight I'm definitely downgrading tomorrow. I'm not impressed with ICS at all with all its teething problems. Its like going from XP to Vista.
Its weird because it only happens if the phone is left completely unattended for a few hours. During the day, there's no irregular spikes at all. That's what I cannot understand

Well you have something which awakes your phone and screen. It might be an app which tries/fails to sync, whatever. Get Better Battery Stats and see what's causing it, you're the only one who can help you.

[Q] Best Rom for Battery Life?

Hey all,
I've been trying out a couple of Roms running anything from Sense 5 Roms to vanilla 4.2. I've had a ton of issues with battery life, and I'm not sure if the DNA's battery is really just that bad or if there are better Roms/kernel combos out there that will make things a bit more viable. Thanks for all your help, I know this is a very subjective question.
18-24 hours battery life with 2-4 hours screen on time seems to be the norm for sense Roms running custom kernels. This exceeds the stock battery life by about 30-40%. AOSP has always yielded poor battery life, not exactly sure why. Perhaps because it wasn't designed for our hardware. Just run a ROM with a custom kernel and if you feel so inclined get an app to control your CPU. Network and GPS off when not in use will give you the most noticeable increase. Use better battery stats app to pinpoint misbehaving apps.

Any Sense Rom that you recommend? Something with a custom kernel included or if not a kernel that works well with it? Thanks!

Contrary to what others say, I actually get pretty good battery life on AOSP ROMs.
On crDroid with crpalmer's kernel (no OC or anything of that sort):

Has i understand it it is some kind of Samsung service battery information/calibration tool and most posts say don't press it! Whoops you did!I have not seen a definite answer around but some people seem to think your battery may return to normal after a few cycles.
The camera issue may just be coincidence not sure.
I learn't along time ago with android don't press anything unless you know exactly what it does.

Best Android 8.1 ROM?

What is the best stable 8.1 ROM for battery?
Try All of Em' One by One, And Let Yourself Know.What's best for ya.
I'm using Pixel experience rom 8.1 and enjoy unlimited google photos storage without losing quality and size of photos videos
Battery is great for me on Nitrogen, but for some reason most people seem to be having the opposite experience. Maybe it is because I have my phone connected to wifi for the majority of the time.

For me Cardinal-AOSP 8.1 is the best for battery life.
Always getting 9+ of SOT only using Wi-Fi, with a lot of Web Browsing, YouTube and Spotify.

Thats exactly it. If you start using data and not wifi, check out the battery usage then. Thats the only thing that stops me using oreo as a daily driver since I like to use data without the insane battery drain.

You have to use the latest version of TWRP.
https://forum.xda-developers.com/redmi-note-3/development/rom-cardinal-aosp-t3707791
Don't go to oreo if your main consumption of internet is through mobile data. Don't know why but "network standby" drains a lot of battery and still isn't fixed on latest NOS . Maybe it isn't fixed in pixel too (can't comment on that just a speculation). And in fluidity or smoothness and ram management I found NOS best with stock kernel.
P.S. : SOT over lte usage 5-6 hrs, consistently tho.

I love MCAOSP (https://forum.xda-developers.com/redmi-note-3/how-to/rom-kenzo-kate-t3669483) - very smooth.
I use it with Agni Kernel and Magisk, no bugs, certainly nothing obvious / serious.
NOS. though the mobile standby drain bothers.
AtomicOS with AGNi Kernel. Nothin' more to say really.
