[Q] Kernel, ART or custom roms : what are your best solutions for battery saving ?

Hi
I've allready configured everything I can with Stock rom and I've installed Linaro / Franco kernel. It seem good. Now, I just want to talk about your own experience to improve battery life with Nexus.
I want to switch to ART, but Google's message is clear : "Warning!"
Does it change something? Have you tested long enough to verify that it works well?
I still have important battery drain and I will study everything I can to improve experience with this fantastic device ! :laugh:

ART worked flawlessly (no issues) for me and noticeably increased battery life but incompatibility with xposed is a deal breaker.

Hello, I have been using ART since a week now and I have never had any major issues.
Some issues I had were:
Apps gets closed when you open them (just retry)
GUI bugs with Any.Do

Go here http://forum.xda-developers.com/showthread.php?t=1574401
And read the op and then try installing gravity box through the download button in xposed box, you will love it for sure

battery life is determined by your personal usage, your person setup, your personal method of app management, and most importantly battery life is determined by the quality of your personal data/phone signal. everything else, including undervolting, only provides negligible results. thats why no matter what rom you are running, no matter what kernel you are running, no matter if you are using dalvik or ART, there are people that will say that it gives them great battery life while others say it doesnt give them great battery life.

[Q]Stock ROM with franco or CM11?

So I recently found out that franco kernel is no longer compatible with cyanogenmod 11. I would like to know which is more battery efficient. Having franco kernel with stock rom or cyanogenmod with the kernel that is shipped with it? Does anyone have experience in this?

battery is all about how you personally use your device, how you set it up, what apps you use, and mostly the quality of your phone/data signal. using either cm kernel or franco kernel can give you great battery life or terrible battery life. any kernel will give you great battery life or terrible battery life.

Both are good and have their (dis)advantages. No one can tell you whats best cause different users have different preferences and needs. Best is to try them out yourself and see what you like best.

I am aware of that. I admit that I am quite the power user which mostly results in a pretty bad battery life. I just wanted to know which option has the better potential with the same amount of usage. I guess I'll experiment with it myself then

im one of the heaviest users you will meet, yet i still see a minimum of 5h+ screen on time every day. set up your device right, and if you have a great signal you will have very hood battery life no matter what you use.

Combine rooted stock, Franco kernel and the Xposed framework plus it's various modules and you will get most of the Custom ROM features along with better battery life and stability. I'm very pleased with that combo.

[Q] Stock + GB or ROM?

Hi guys,
Thanks for all your help so far! Love this forum.
I'm pretty noob when it comes to Android customization, so I wanted your opinion: I'm trying to decide whether to run a stable, fast ROM, or simply stock with GravityBox and Franco Kernel.
Here are my considerations:
I'm not an advanced user, but I do use my phone a lot for work and personal things like email, browser, gps, videos, etc. Since I rely on it a lot, stability is pretty key. However, I get really bothered by some UI restrictions on stock (in particular non-customizable Quick Settings, non-customizable status/nav bars, and no PIE, but other small things count too). GravityBox is sufficient for the customization I need, but at this point speed and battery life come into consideration also. I wouldn't mind a longer battery since I use the phone pretty heavily. Speed is a consideration in that it would help me get things done faster.
So I guess my dilemma is whether I should use stock while relying on GB for customization and Franco kernel for battery efficiency, or if I should run a stable, fast ROM like SlimKat for the same purposes?

Xposed will slow things down so IMHO if a ROM has all your needs, use that.
That said I use a ROM and xposed

Exactly. But even I prefer stock + GB

Thanks for the replies guys. What ROM would you recommend for GB-like customization options, stability, and good battery life?

Yep, SlimKat, If stock Slim is missing a feature, about 50 people in that thread build their own Slim with some mods. One guy builds a version that has a DL/UL speed indication, L-style navbar buttons, and a bunch of other things.
Kernel, use Code_Blue. I prefer it over Franco. Just don't use the stock Slim kernel.

I'll add my usual comment..... Lol
Roms have near nothing to do with battery life. It's setup and usage that make or break battery life.
Don't factor battery life into Rom decisions.... They're all the same. ?

The only way a ROM can really affect battery is if a feature is designed poorly or there's a derp in the build..
But yeah, you can't really improve "ROM battery life", you can only make sure there aren't any problems which affect it negatively.

Really? I have the stock ROM and xposed with six different modules and I haven't noticed a substantial performance difference. Perhaps it's one of the modules you have installed or maybe xposed doesn't play as well with your ROM as it does with stock?

Xposed is always going to slow it down. The amount, however, is different for everyone.

So what about things like Franco Kernel, which claims to slow down processor when not in use to conserve battery?
And thanks for the help guys. I flashed SlimKat for now and am so far pretty happy with it.

Might not be noticeable, or it might be obvious, it's still always going to slow it down overall. Different experience between different people.

I've used every Rom and kernel almost and after setting each up how I regularly do, and with similar usage patterns always....my battery times were always similar.
I never play with the clock speeds I should add......but that's my experience. The roms or kernels I used made no real difference to my battery life.
?
Yes I've seen lots of "claims"....And guess what, many believe them. ?

Bad battery life

Hello,
I have a question, am I the only one having SoT this bad? I'm on the EMUI 8.0. WiFi and Mobile data always on, auto brightness. I mostly stream music through Spotify and use social media apps like Instagram. Is there any possible way to improve the battery life?

For starters turn off mobile data when you dont need it, also check if some rogue app is draining battery.

I don't know if this would help, but if your bootloader is unlocked you can try the chihayafuru kernel. Extended my battery life significantly.

What settings do you use? I'll flash that kernel during the weekend.

I didn't alter anything. I just flashed the kernel, that's it. Although i'm running RRos with it.

Lowered minimum frequency to 408mhz and still works fine.
Would like to put to sleep some cores, tough.

Which custom ROM/Magisk module/kernal is best for extension of the battery life

Dear everyone,
I' ve trapped by the battery issue of my phone. I absolutely love this phone but the battery life is so weak to me. Since my last phone is Mate20p which can be used for 2 days, I feel OP7pro is an only one-day phone and even need to charge twice in a day. However, I find there are so many alternative choices for me like in terms of the kernels, ROMs, etc. I am a new here, just wanna know which project is the best for extending the battery life? Thank you guys so much. Oh, by the way, I expect these projects have not many obvious issues for daily usage.
Kind regard,

My GM1917's battery life benefitted greatly from just NoLimits Magisk mod debloat. No issues at all. Stock OOS 9.5.11 and stock kernel. Also have forced 90hz and fixed resolution to QHD+.

NoLimits + Renovate Ice + Arter79 kernel has done me wonders. ~ 10%/hr drain on screen .3-.5%/hr drain standby.

Just debloating might improve it...

Install a good kernel (smurf kernel, kirisukura) and set it up for battery saving
