As the title said, i'm looking for a kernel to improve my nexus 7 battery life. I do not play games, my most concern is improve battery life when browsing web. Anyone can help me? I'm quite busy so i don't have time to try every kernel.
Thanks in advance

ElementalX 1.8 beta gives me great battery life. Here's a link to it: http://forum.xda-developers.com/showthread.php?t=2389022

Thanks a lot. Gonna try that soon . BTW, how much screen on time do you get in a single charge?

Screen on time is taking about 20% instead of the 60% I used to have ( I normally have it on lowest settings). Lasts me a day without charging.

This of course is BS, a kernel can't alter the percentage the screen uses in such a ludicrous amount. But if it works for you, great :angel:

Kernels can affect screen time in "ludicrous amount" when you overclock, use the device for a period of time, application usage, GPS, Bluetooth, and display settings etc.

No. Not in the amount you specified. Complete nonsense, with all due respect. Underclocking, undervolting, all those things will never yield your result. One hundred percent impossible.

Well I don't know what to say to this. I know what my battery stats were and I wipe them (and I continue to wipe them) daily. Maybe my nexus is special. Come to think of it, it has had some problems before. Maybe this is a way for it to make up to me

Its true, battery stats have no effect on battery life. I wipe them across ROMS because the battery stats file can get messed up when switching ( it has happened to me before ).

No, it can't. Wiping battery stats has no influence over the battery indication whatsoever. As per Google themselves.

I never said that the battery stats file had influence over battery indication. Like in the link you provided :

That is, it has deeply significant things like "app X held a wake lock for 2 minutes" and "the screen was on at 60% brightness for 10 minutes."

Interesting things happen when you wipe the cache. This is from my Nexus 7 during Video playback. Seem like the battery consumption gets attributed differently.
Exactly the same setting, ROM & Kernel, both cases I use MX Player Pro with H/W+ accleration to playback 720p videos. Only difference is in first case Screen battery consumption 83.5%, the other 57.7%.

Get Elemental X 1.8 and run it at stock clocks (1.5Ghz CPU/400mhz GPU) will probably give you the best battery life. If adjusting a lot of settings when installing a kernel is a hassle to you, get Bulletproof 1.3 instead. Bulletproof have the same developer(flar2) as Elemental X, it is basically a developer optimized version of Elemental X running stock clocks & optimized for Battery life.

I wipe them because like I said before, the file can get messed up when switching ROMS. It got messed up on my LG phone before so I wipe just to be thorough.

It has gone some time now and a lot of new kernels and roms have surfaced.

CM-based ROMs gave me better performance and battery life. Currently, I'm using Arter97's CM 13 ROM+Kernel and I'm getting longer screen on-time.

On ex kernel side everything is default except i/o changed to fiops
On l speed side(im using beta, u may choose stable or beta) i choosed recommended profile and after selecting advanced ui i choosed as shown in screenshots
You may change as per your liking. I got no problems with performance and battery and everything works fine
arter kernel + his cm is a good combo
just like sultanxda builds for 1+1

Pixel Experience, maybe? I haven't big problem in gaming. Playing [email protected] CGSS and Million Live between 1-2 hours nonstop using 3D high still no lag even I installed much app.
Apologies if this has been asked before i could not find anything also afraid to try flashing different rom incase I brick my phone! What is the best custom rom for battery life? I've been using pixel experience pie getting around 6 hours of SOT. I don't game just browse reddit Facebook and what's app was wondering if i could push it bit more than 6 hours

I've recently fallen in love with xtended. Using it with the stock kernel, no games, only some light xda browsing, telegram and some YouTube. I easily get 11-12 hours SoT. You can give it a try.

I've been using AOSiP and have not looked back. its great on battery and buttery smooth.

I'd come back with an edit for MSM tho. Yeah, it's nice and i guess SoT is very good, but idle is... Lost 6% in 9 hours first time, then 3% in 5 hours. Even with my deep sleep tweaks and nothing turned on. That's a big no-no for me. So like you said, AOSiP is a really really good choice (IMO at least).
I'll start with the aosip, used it on my oneplus 5t liked it

No, no need for Greenify since i just don't use social media crap apps. Those are battery drainers. I do, tho', tweak the doze settings. Also, i use a different brightness app since the android's one gives too much brightness all the time and i don't really like to adjust it every time i unlock the phone. And the kernel is tweaked a bit, since i don't game much on my phone.

Basically its not applyable to most users. So your screenshot with sot time is very misleading without these details. If you underclock miui, dont use social apps, dont game, and lower your brightness, im sure you'll get something like 14-15h SOT. Because i often get around 10h SOT with miui, without modifying anything, just using phone as it came. And i do use social apps and enjoy an occasional game

I do play games, just not heavy ones. And the brightness is just a little bit lower, at most 10%,the kernel is not underclocked, it's just tweaked so it doesn't jump to high freq for just tapping on the screen. And yeah, social apps do play a big role in that, but only in deepsleep. For SoT, it's the same, I don't use social ones, but I use 9gag,which is known to drain battery, or telegram or WhatsApp so it's basically the same. But everyone's usage will be different. I just recommended a ROM and kernel, I didn't say it's the best or that people will get the same results as me.
Just received the 5.1 update on US unlocked S21FE. Still exploring changes.
There's been reports of the 5.1 update causing issues on other Samsung devices.

Been with One UI 5.1 since approx 2 weeks, better battery life for me in idle, a bit less in use but nothing bad.
My speaker seems horrible, sound is not as loud as before and less clear, it's like old gen phone. Or it's just me. But nothing has changed significantly in this release.
Sound quality has gone bonkers. Can't hear anything after update. Speakers are useless now.
