This is a rather simple question do different roms really have better battery life then others or is it more of the choice of kernel? Do roms effect battery life as much as the choice of kernel? I currently have vipers Rom and just maxed out at 3:20 of screen on time with stock battery with underclocked and undervolted Sebastian kernel and want to no if switching to elegancia Rom would really make a difference in battery at all
Thanks

Hi,
Battery usage is a very subjective matter.
Everyone uses their phones differently,so , judging battery life between people is hard.
Yes , some ROMS are better than others.
Yes, some kernels are better than others.
It is the combination of the right ROM and kernel for you that is going to matter.
And no one can tell you what that is.
Experiment for a couple of days to see how they work.
READ what other people are saying about them in the threads.
OR,
Get a couple of spare batteries,and carry them around with you,and then , power is never a problem.
Guys is there any way to increase battery life on custom rom ? I'm using flyrom and my battery drains faster...
try greenify.
Battery life really depends upon user usage, and other things (the kernel, that I'm talking about).
The kernel's not much to worry about, for there are no wakelocks, and stuff... But, if the ROM is "buggy" (i.e. creates unnecessary wakelocks), one can't do anything but go into the source to fix it.
But, about the USER USAGE, the reason for battery draining... Here's something that featured on the XDA Portal a few days ago: Battery Saving Mega Guide Celebrating User’s 2000th Post.
Head over to the original thread, here: http://forum.xda-developers.com/showthread.php?t=2601318, and try following the steps there. LMK, if it helps
Hi
A friend of mine is endlessly complaining about the bad battery life on his stock nexus 5, the phone is off the charger at 7am and is all but dead at 4pm
Being a nice guy and all, I want to help him out by offering to install a ROM that optimises battery life.
Can anyone suggest a good rom for the task ?
If such a rom exists and battery life can be extended to 15 to 17hrs I might jump ship from my LG G3
None
roms have absolutely nothing to do with battery.
battery is determined by your personal use, your personal setup, apps installed, and very much the quality of your phone/data connection. there are other things that'll influence battery life slightly as well, but these are the main things that determine your battery life.
Turn off auto and set the screen brightness display to 15%!

Autobrightness isn't too bad if your ROM allows you to change the values/levels
Also, "Lux Autobrightness" is useless for saving battery on an LCD screen since the backlight is still the same brightness. on AMOLED (aka not the Nexus 5) it would help, however.

so we shouldn't expect any battery improvements when Android L is released ?

its possible, a small amount. but that would be from new code that makes something more efficient. but, i personally, dont expect much difference in battery life.

not sure I agree with you, project volta looks like a concerted effort from Google to do exactly that.
Funny. I always use Auto-brightness and get 4 hours SoT at least twice a week. Other times, I get a little over 3 hours or below.
The best battery life for me is with elementalx 1.05 kernel with a stock rom. 2 days stand by and at least 5 hours sot is the usual verdict.
But i think the problem here is how your friend uses his phone
Different ROMs do have different battery usage. Even with the same kernel. He could stick on stock with elementalx aosp kernel. Then mess around with trickster mod to suck out the most use. Only use the high power goveners when needed. Then switch back to low power for general use. Honestly, had my n5 for a month. Also had a n4 before. The n5 battery isnt much better. Biggest downside. Just doing nothing its fine, but if I play some games on the train it dies in no time.
Some ideas
Vanir
Slim
Purity
Cm11
Vanir with elementalx was good for me battery wise. But after a certain nightly I was getting alot of heat and battery drain. Im now using sabermod carbon with elementalx.
Turn Location off. It has the biggest Impact in Battery life time.
"Best" ROM.
There is no such thing as a best ROM. The question itself is ambiguous. "Best" is obviously a subjective term.
What I want from a ROM may well differ from what you want from a ROM, ergo - what is best for me could be worst for you.
If you are asking what the most popular ROMs are, or which ROMs people are using, you can see which threads stay around on the first few pages (and have the most posts) in the Android Development or Original Android Development forums. You can also see what other people are running by reading the What are you running on your Nexus 5 thread.
If you are asking which is the most stable, being a Nexus device - they're all pretty stable.
If you are asking which is best on Battery, ROMs only affect battery if they have a feature that is badly coded. You will likely be able to read about this in the ROM threads. ROMs do not impact battery life. The only impact to battery life are your apps, your settings, how you use the phone and mostly, environmental issues such as Phone Signal.

"Best" Kernel
Also, please note that as above, "best" is still subjective. What we all want from a kernel is different. Again, many people have the misconception that Kernels affect battery life. Let's get this cleared up. Although Kernel devs will build in optimisations and efficiencies that will improve battery life, these are very, VERY tiny...and if 1 kernel has these optimisations, they likely all have.
People will often say "Kernel x is better than kernel y for battery life". This is actually wrong. Kernels respond to user settings. Setting up the governor to favour either battery life or performance is simple enough to do, you just have to do some learning. The reason people think Kernel x is better than y is because developers set their kernels up with their preferred governor settings. This is what we refer to as out-of-the-box settings. The out-of-the-box settings for kernel x may well produce better battery results than the out-of-the-box settings for kernel y, which favour performance. The fact is, you as the user have the ability to tune kernel x or y to perform the same, be that battery or performance - so start learning how to do this yourselves - that way, you can choose the kernel based on the FEATURES you want, and not the fictional performance benefits of one kernel over another.
Hope this helps

with this guy
I used about every rom and kernel.... And my battery life for me, with my lean setup and usage was always 24 hoursish total and usually over 6 hours screen time on all of them.
So no one will ever convince me that different kernels and especially different roms affect battery life any more than in the smallest ways. Definitely not enough difference to base a choice on solely.

Well said. I hope you don't mind but I've linked your well written response in a Reddit post. Users there argue daily over which ROM or kernel is best for battery life despite my best efforts.

Not at all. I'm just copying and pasting it wherever needed now.
