[Q] How to maximise battery life? - Nexus 7 (2013) Q&A

Just got myself this tab.
Any tips on extending battery life and which roms, if any, help with this?

A custom kernel should do the work. Try ElementalX or Glitch or even Franco if you're not very experienced. Make sure you set the Location to Battery Saving also. Settings>Location.
Auto-Brightness is good but also a bit of a battery killer. Do without it for more juice.
I'm also a moderately new owner of a Nexus 7 and from my experience so far, every single one of the custom roms are really really good. Its very hard to choose. I would recommend CarbonRom and CleanRom

Kernel and rom for battery

Hey guys,
I've tried the codename android ROM and i've loved it, so with this rom my battery draining so fast.
So i've installed the rom minco v5 with the franco kernel and its really better for the battery. But with this rom i dont have any option to customize my phone.
So my question is, is the rom have an impact on the battery or just the kernel do the job?
So can you post your rom+kernel combo with your battery draining experience ?
Thanks

I personally have found less impact on battery life on rom/kernel combination than I felt I should have. My biggest boosts to battery life were disabling google now and putting the phone into edge mode when im not needing high speed connections.
from a logical point of view, it's more likely that more customization options will eat more battery, since there's more code running than stock. don't be mistaken, it's personal, your SPECIFIC usage will dictate battery drain. for me, stock has the best battery life.

[Q] Battery life: stock VS custom roms and remedies

Hi guys!
I've been playing around with my GNex (GSM, stock 1750mAh battery) since last july and my biggest concern is (still) the battery life.
I've noticed that the couple stock rom + stock kernel (the ones the phone come with) is much better than any other custom rom+kernel.
Here comes my (maybe stupid) question: is the battery life somewhat related to the (de)odexed status of the rom?
I mean, I've been looking for all kinds of solutions to take advantage of those features offered by AOKP or PA without suffering from BL issues, but I find silly to sacrifice stability/smoothness/responsiveness/always-on-connection/brightness/whatsoever to gain not that many mins of juice. And I really wonder what is the sourcery Google adopts to make its roms so stable, responsive and battery friendly (e.g. no custom rom/kernel can achieve as much BL as the stock ones). Put differently, with the stock rom/kernel, I can leave 3G always on, auto-sync always on, haptic feedbacks on, location services always on (but GPS) and the battery survives for more than 24h; while, with custom roms/kernels, I could switch everything in the list off and still the battery wouldn't last that long (ceteris paribus).
Could you, please, explain me how it works?
Is there really no way to improve BL other than those listed above?
And, finally, does odexing the system apps (on custom roms) do the trick?
Cheers!
P.s.: the answers I'm looking for may already be in other threads.
If so, I apologize, but I tried googling different keywords many times, and got no interesting results.
For me the biggest source of battery drain is the screen by far. Maybe you enjoy custom ROMs more than the stock one and you keep the screen on more I would think that a custom ROM would be more battery friendly. Which ROMs have you tried?

Lol, maybe you're right!
Until now, I tried AOKP and PA roms and franco, AirKernel, GlaDOS and stock kernels (all possible combinations). I found that PA and GlaDOS are the best custom couple, but still not comparable with the factory ones.
However, even tough I have no technical numbers, the usage on custom stuff had been more or less the same as on stock things (although I became a pie-control addict). And what I know for sure, the BL gap is mostly due to screen (i.e. by staring at the launcher home screen for 5 minutes, the battery drains faster with custom roms than with stock roms - still, ceteris paribus).

I know that's strange. Things used to work as you say with my HTC Desire. But since I've switched to the Nexus S (and then to the GNex), I strongly preferred stock stuff just because of battery life

A ROM that would suit me?

I have flashed multiple ROMs but can't find one to suit my usage. I know about the extended battery , have had them on other phones in the past. But I'm just looking the software aspect. What roms due fellow flashers recommend for a heavy user that has the best battery consumption? Thanks for your time.

I find LiquidSmooth with BMS kernel provides a pretty good battery life. I'm not sure how you use your phone throughout the day, so i'm not sure if it's what you are looking for

I hope people help

I hope people help. I'm running ROM v7 Minco would ask you to run kelner the best and most battery saving. I find this a rather drain the battery or can anyone share your 1st rom for best battery not?

There is no correct answer to this. Different folks have different setups that work for them. It is all experimentation on your part.
Run something like Better Battery Stats and figure out what is draining your battery. Then figure out ways to conserve that battery.

Try leankernel for 4.2.2 bro...
Try latest from stable builds

Or try light or near stock ROMs like purity

[Q] Could I get some advice on underclocking my N7, to get the most battery life/scr

Hi guys. I've been on XDA a long time but I know next to nothing about under/overclocking safely.
I basically just want to use my N7 as an e-reader for a while and I was just wondering what your thoughts are on what the best rom/kernel combo/settings would be for achieving the best battery life and screen on time?
I'm currently running CM 12.1 with the stock kernel and power saver switched on. It's better battery life than on stock but not a great deal more.
Thanks!
