We use kinds of kernel and cpu tools ,does it really save power ?if so,which kernel do you think is the best..Thanks so much
I like PA rom and i just want to know which kernel would be better......
Cant say whats best kernel. Kernel is fone depended. Some kernel work well for some ppl but wont work with others. The most popular is BMS and KT747 kernels. Give them a try. Im on bms stock battery get about 13-15hrs with 7hrs sleep mode and 3-4hrs of screen time

Undervolting is over rated. If lucky may gain 30 minutes on a complete charge/discharge cycle. Too much can cause reboots and/or increase battery drain.

i see,thanks very much:sly:

IMO its pointless to mess with the CPU settings in order to save battery. Seems like the major cause of battery drain is always going to be screen on time.
Hi,
Every KitKat Rom that I tried was affected by some kind of battery draining bug which has to do sth with Google Play services. Can you recommend a fix which works by doing it a single time? Uninstalling/stopping Google play services fixes the problem for a few hours only.
However, I would prefer a rom which is not affected By the bug out of the box.
I'm testing Racpu_ cm11s. Was having Google Play service wakelock, but learned somewhere on Oneplus forum about this: Install Disable Service from play store, switch to system tab, check SystemUpdateService. That somehow eliminates the wakelock. Today is 2nd cycle, 4hr screen on for youtube netflix under wifi, still rocking 48% of battery.
Cool, Ty, didn't know about this Bugfix,will try it. Why are you testing kitkat Roms in 2016?

Please tell me about your (major) findings about your research. How do you log and observe your the battery consumption? Which configs for sync, screen-of-gestures, brightness ?
I can share my findings also, if you want.

Sure. I wouldn't call mine "research" tho haha
Now I'm on slimsaber kk build, about the same SOT, feels slightly smoother than cm11s maybe.
Did my trick for the battery drain, but now Google Play services FC unless I set location to device only, oh well...opengapps btw.
What have you tried out so far? Did my trick work for you at all?

Since I opened this thread, I am on Karbon kitkat which seems to be a fork of Slimxxxx
Fortunately, I did not get an always active bug until now, so I didn't try your Bugfix.
How much SoT do you get with your roms and which configuration.?
Most times I get 4 hours with the following config
- brightness static 50%
- sync, tapToWake and offscreen gestures off ( just in case...)
With following usage profile:
- no 3d
- no video (out of short clips)
- chrome, messenger, quora, Google news
- telephone 45min
- 75% WiFi, 25% 3G

With Racpu's cm11s and Slimsaber KK build, I didn't get to use the battery all the way to like 1%, but I already got 5hr SOT before that. Here are more details.
Racpu's:
- auto brightness
- youtube and netflix a lot, some xda and chrome, abou 30min phone call
- always on wifi
- greenify in exposed mode
Slimsaber KK:
- auto brightness
- 3hr LTE, rest on wifi
- about 2hrs of youtube and netflix
- 40min navigation with google maps
- a few camera shots
Don't think this is scientific enough, but hope it gives some idea on my usage.

YouTube, video in general does really really impact SOT measurements. You get about 1,5 to 1,8 times more, I measured it a lot. Navigation is the other extreme : 3d, GPS and most times a high brightness because you are outside (on daylight)

Ah OK, that seems right. I didn't do such detailed research
Now I'm leaning towards what most people say: Battery life depends on how you use the phone.
Also, I think OPO has an amazing developer community and all roms are of high quality and yet retain their own unique qualities like functions etc.

Hey guys … we've had quite a bit of development in a very short amount of time since release. There are some very talented developers out there and a dedicated number of people making our already great phone even better.
So, I was curious to see at this point what Rom\Kernel Combo everybody is running to get the most out of the battery while maintaining performance!
Sound off on which rom\kernel combo you're using and post battery life screenshots if you have them!
Thank you to the developers that make this happen, we couldn't have gotten here without you!
I guess there is only one stable rom xXx

SOT varies and depends on your usage.
Xxx+cleanslate
If you want a balanced kernel with a really good battery life, you should go with franco kernel. I achieved very good stand by and screen on time, even on the currently battrry-buggy OxygenOS 5.1.8. And if you want a light customizable ROM with quiet a few goodies, go with Renovate 3.2.

Is that stock options with Franco?
If I pick up my phone and use it all day in bed when I'm under the weather or when I'm home for the day with nothing to do I can get 7 hours of screen on time with constant usage at half brightness. When I am at work and have the phone with me and do a little gps etc I can get about 6 hours. It all depends on your usage and also your cell signal. The worse your signal is the faster it drains the battery. The more GPS you use the faster your battery dies. It doesn't matter which kernel I am running, (I'm currently on stock 5.1.8 with Magisk, Xposed & ElementalX) battery life is pretty much the same.

if you won't stop to believe that rom and kernel are responsible for SOT and standby drain you will never be able to 99.9 control and manage your battery usage.
it's all in user space as long as there is no know battery hog (know bug) in either rom or kernel.

I've been seeing people with insane 9-10 Hour SOT but I barely get 6-7. Not saying that's bad but I don't play any games so I know it could get better. Can anybody help me out? Much appreciated.

Why not use beta? It's fine for me. Literally everyone say bad battery life after an update. Perhaps give it some time.
If I'm looking for a lightweight and stable ROM that improves my battery life (this one is very important), which one is the best?
I don't care about extra features and customization. I just want stability, smooth experience and battery life.
No choice

Official Lineage 17 is pretty good. Smooth and most importantly STABLE.
4h+ SOT from a full charge on (underclocked) ElementalX.
BlissRom for sure, 5h sot from full charge on stock kernel. Stable, ota updates and lots of features
If you have an european pixel, you need to flash the special kernel, otherwise no sound in calls

You don't need a guide, it's all in the ElementalX zip
Flash in TWRP and the installer will start automatically, there you can select the max frequencies for the little and big clusters.

Those estimations totally depend on usage, but in my experience it would last a day, with below 10% left at the end of the day. So the battery does not offer a usage time anything better than average.
