Hi guy, which is better between stock or cm10.1 for battery life if it used the exact same way ? i mean the exact same app and the exact same sync configuration ... things like that ?
You could try and tell us
Personally i haven't tried CM

CM uses the same kernel as stock, So I don't think there'll be any difference in battery life.
Battery life is more a matter of user and device then kernel. We could run the same rom, same kernel and see very different battery life due to apps installed, set up, and how we use the device. This is a common known fact.

So my N7 arrived two days ago, and I immediately unlocked, rooted, and flashed some things. Currently running Codename Android with Trinity Kernel.
My battery is absolute crap now though. Its been two days so I thought the battery more but have settled by now. All auto sync off, brightness at lowest setting, apps sync every 4 hours, still bad! Does calibrating still work? I read somewhere that it was debunked and it didn't work. I would appreciate any help. I mean, my Maxx is getting better battery life.
I uploaded some screenshots of the battery after only 1 and a half hours.

My Battery life is without doing nothing ~1-2weeks (in my with 58% xD)
Use Stock Kernel

Go to the motley kernel thread in Original Development. He provides a mirror link for the stock kernel
I loved Trinity and the TKT app but for some reason im getting much better battery life with motley kernel. I originally did some troubleshooting and fixed some apps that were causing wakelocks. My battery life got a little better but not by enough (could only get 3 or 4 hrs screen on) so i switched kernels.
If you feel like experimenting do this:
Nandroid
Wipe Cache + Dalvik
Wipe System
Factory Reset
Flash CM10 nightly (any rom of your choice)
Flash GApps
Flash motley kernel (i used the 484 GPU version)
Fix permissions
Reboot
I get awesome battery life now and performance is great.
Your title should be something like this: "After rooting and installing battery draining rom and kernel I get bad battery life on my N7"
Stock JB and kernel should yield decent batter life.
With the proper rom and kernel the Nexus 7 easily match or better the googles battery life claim.
FYI the latest Trinity kernel is a battery hog.

if you use it at 1.7ghz it will be, but thats obvious. at 1150mhz, its as quick and wonderful on batteries.

I wouldnt go as far as saying its a battery hog, but i ran the kernel at stock clocks and while performance was much better than stock i still had tons of drain that i now dont have with a different kernel.
Ran Trinity kernel at 1150mhz and had awful battery. Back on stock ROM and kernel and seems to have improved a lot.

I feel like the battery is pretty decent...
Get off those custom Roms and kernels until you understand how the device is meant to perform.
You appear to have 87% after 1.5 hours, that equals about 10 hours, how is that bad? I get about 8 hours if I am intensely playing with screens, apps and games, 2 days if I'm not doing much. Loses 2% at night with wifi off. No root.
trinity kernel and the pure aosp rom, at 1150mhz. id say not bad at all..
Trinity Kernel is a good kernel. I went overboard by saying it was a battery hog. I did have it overclocked up to 1500hz on-demand and it ate up battery faster then I would like. But this is with the newest one, a few of the older ones worked out better for me though.

yea, overclocking is mostly for fun, definitely not for battery life

I have some problems with *wakelock*
experienced user told me that Stock(AOSP 4.2.2) is better than Custom (CM10.1, AOKP...) (in terms of Battery life.)
is this true? maybe someone test?
i have Nexus 7 3G (AOKP off + franco Kernel)
It's impossible to give you a truly correct answer because there's too many variants which can make battery life differ.
As things like apps, usage, ROMs, kernels, mods, the device, tweaks and many other things can all have different effects on battery life, it really is dependant on the specific situation.
So if I was to have the 3G model (as you have), be using the same ROM and kernel combination, have all settings exactly the same, have exactly the same apps installed, use the apps for exactly the same amount of time and have the same mods/tweaks installed, we could still quite easily have our battery life last a different amount of time.
Due to that, that's why it's always best to just test them out for yourself so then you'll know exactly how your battery will perform in regards to your usage

The ROM makes little to no difference whatsoever. Battery life is more affected by the kernel and your own individual settings.

But some ROMs claim to have better battery life than the others (CodenameBattery, SuperCharge Series). Are they talking nonsense?

Odp: [Q] Best Battery life. Stock or Custom?
I use stock 4.2.2 rooted in two weeks now, and the battery is very good. Try to stick to stock in one week or so.

Some could absolutely be talking nonsense but others could actually be telling the truth.
They could have certain tweaks in place that will indeed improve battery and could also have more power saving apps included. There's so many variables that without actually testing them out for yourself, there's no way of knowing whether it will have better battery life or not.
I use a custom ROM on my gnex simply for color control, but in my experience custom kernels never improve battery enough to make more than a very minimal difference. I stick to stock with my 7 for multiple reasons, one being certain EA games won't download data while using custom kernels. You'll see people claiming custom kernel's get them 9 hours display time ect... Well I've gotten that on stock depending on what I was doing with my 7. My average is usually more like 5-6 over 2-3 days as I use it more for gaming than anything.

Like previous members have stated, it's not possible to give you a definite answer as to which gives you better battery life. When I received my N7 I rooted and installed a ROM and a kernel. Ultimately I revert back to full stock android for many reasons. One, battery life was much better on stock kernel than a custom one. I didn't need a custom ROM either. Only on my N4 would I need custom software installed because recently my mother has been using my N7 a lot so my N4 is what I use most now.

Hello, I just wanted to ask which ROM has the longest battery life (in screen hours)...
The most battery frienly rom i have ever tried was liquidsmooth...
What do you think?
Guys please help out a new N4'er like myself. I'm stock right now and the number of Roms are kinda overwhelming. I'm only interested in battery life. I'm not in the mood to go flashaholic searching for that one ROM.

The most important thing is the kernel and the apps you have installed.
Find the ROM with the features you like and flash a battery friendly kernel. I currently use Matrix kernel because the lower CPU idle makes the phone sip battery while the screen is off, leaving you more for actual use.
Good luck. Also, INB4L.
There is no "best Rom" for battery. It's all in how you use your phone, what apps you use, the signal strength in your area and of course the kernel you flash and how you set that kernel up.
100 different people could reply with the Rom they feel is best for battery and which kernel and you still may have different results than they do

From what I've learnt the kernel directly dictates battery life.
but I've personally opted for lean roms. If you're using a heavy rom and frequently putting load on the processor surely the battery will burn down fast. I've been using rasbeanjelly bouncing between franco/trinity and the battery life has been awesome for me.
Btw franco's r121 is godlike for me right now, in terms of both performance and battery life.
Im using liquidsmooth which comes with matrix kernel in the official release.
Im getting very good battery life probably because the cpu min is lowered to 288mhz instead of the normal 384.
Performance on the rom is great also with antutu scores over 20000
Ive tried francos, for some reason it didnt quite work for me but it is very popular because of the great balance between battery and performance. Youll get even more battery life out of faux and if you want blazing fast speeds try out trinity
Battery depends on the kernel, not on the rom.
Battery life depends on a number of factors, kernel being one of them. If you set your screen brightness at maximum high, you will see battery drain like water down the toilet. Screen brightness is the single major factor. Kernels don't really matter. It's the apps you install and run on your phone that can kill battery life. Apps like Facebook will suck down your battery like there's no tomorrow. Auto sync'ing and pushing and pulling data to and from your phone will make your battery life go down really fast. GPS and using google maps can contribute mightily to your battery woes as well.
To keep your phone from dying, just get an external battery pack and charge your phone as necessary. I have a 5400 mAh pack that can charge my n4 at least a couple of times. I never worry about running out of battery and I use my phone the way it's supposed to be used.

Battery does depend on the rom...
For example a linaro compiled rom will require less work of the cpu to move the os due the optimization.
Also some rom have init.d scripts that can help battery life a lot and there is the possibility that some programs like systemUI can have a little bug that the user dont know about it but its draining battery
The battery life depends on a lot of factors of the rom

You are completely wrong. As said before, battery life depends on a lot of things. The kernel is a big factor, but not everything. The way u use ur cpu, the scripts u apply or ur build.prop configurarion can be very decissive.
IMHO paranoidandroid 3.1 is the most battery saving ROM

Which has better battery life stock JB or Paranoid Android with Franco Kernel?
Try it yourself, every user has different usages..
But using Franco will improve your battery
The above post is a bit contradictory but it's right in saying that the experience varies from user to user. Some say that the stock ROM and kernel give the best battery life, others prefer different kernels. For me they all seem good enough to get through the day so it doesn't matter too much.

Coming from an LG G2 (long story), battery life is what I miss the most. The nexus 4 has about half the screen on time than my g2 did.
I'm already unlocked and rooted but still stock ROM. Are there any Roms that significantly improve battery life?
I found smart 3G on Cataclysm to be pretty good at saving battery.
ROMs and kernels have little to do with battery. Your usage, signal for mobile data and WiFi, screen brightness, your configuration for location services, gps and the like and your apps determine your battery life.

I'd try Paranoid. I used it for a while after using stock and I found that the battery improved.
roms have absolutely zilch when it comes to battery life. only thing rims can do with battery is reduce it. generally, the more added mods/features a rom has, the worse the battery life. but not always. battery life is determined by hiw you personally use your phone, how you set it uo, what apps you use, and the quality of your phone/data connection. everything else, including kernels, have a very minimum effect on battery.
Well
When I was with Carbon, the play store thing killed my battery to 3hrs on screen time
Switched over to Purity Rom with Hells kernel and I have 5-6 on screen time
WiFi on all the time, no data or GPS or Bluetooth.
Mostly Reddit and a game or two, and a movie

Okay, but why is the battery life better with an another kernel?
I use the HeelsCreed kernel and Mahdi rom. My battery life is better with the HeelsCreed kernel as with the Kernel of the Mahdi rom.
P.S.: I know my english is bad, sorry for that

set up your CPU and everything else just how the kernel sets it up for you, and you'll get the same battery life. be more active, set things up manually.

can you tell the story please , anyway ROM has weee little to do with battery life , its mostly on how you use it and the kernel you are using as well as sync loops and dodgy leaky apps , my personal setup is rom = paranoid android and kernel = hellsdoctor , using synapse app i switched the maximum clock speed to 1.2 Ghz , and changed the maximum core online to two, gpu is overclocked by default , rest is, location settings are turned off only turned on when required , brightness is set to 50 % , no dodgy apps on the phone , i can squeeze about 5 and half hours sometimes 6 its good enough for this battery size though and hope it works out for you :good:
