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.

Hello I am wondering whats the best kernel for battery life on CM7 would it be faux or stock? And plus can I just install the faux Cm version start at 1.0 ghz to 1.4ghz, so by overclocking it means it will have less battery life? Could I just install that kernel and leave it at 1.0 ghz? And is the faux kernel better than the CM7 stock in terms of battery and what about performance?
New to this stuff!
Thanks people!
What CM7 are you running? It makes a big difference. Also, battery life is different for every person. So to say one kernel is better than another is based on your use. Now I did notice a difference in battery life and performance when I flashed Faux's kernel. But best advice? Wait a couple days on stock, see how it is. Then flash Faux's or the any other kernel(as long as it CM7 based of course), to compare the results. Of course when your comparing make sure your phone usage is the same, or as close as you can get it

Ya. I flashed the DS OC/UV v.0.4.8 first but like faux says the battery readings were crazy, going up and down all time, I didnt know how much battery I had left. And this was after I calibrated my battery of course. Im using the CM OC/UV v.0.4.8 kernel and its great! Great performance and awesome battery life! Right now I got 38% left with moderate to heavy use on 10 1/2hrs. I posted a few screenshots of my battery use using Battery Monitor Widget Pro. I couldnt post the battery use one cause I rebooted my phone a couple times changing my theme. It reads like 2hrs on battery instead of almost 11. Also I posted a Antutu benchmark score as well. Try one see if it works, no two chips are the same, if it doesnt, he's got 4 different kernels. Plus there's the other kernels that I havent tried yet. Hope this helps!
Overclocking will reduce your battery life but increase your phone's performance. Use an app like SetCPU to choose your clockspeeds and voltages. I don't recommend messing around with voltages until you're much more familiar with over/underclocking.
I've used faux's kernels off and on and never been able to get my G2x to be rock solid stable versus the cyanogenmod kernel but it certainly did increase my battery life by a noticeable amount. Right now I'm running the Trinity ELP kernel and undervolted it even further and I've had absolutely zero issues. If you try faux and don't like it, give Trinity a try.
I prefer Trinity ELP or Faux DS versions if I am in battery savings mode depending on the ROM I am using.
Hi!
Ok, i'm not good in writing especially in english so here we go
From all kernel that has been released lately, which one do you recommend for having the best battery life in term of standby??
My opinion is Sebastian's kernel in ARHD 6.5.1
it gave me mostly 2 hours for 1%
but i have new problem now cause i flash ARHD 6.5.3 and then restore boot from 6.5.1 NAND back up and now my wifi gave me error
(but this is my problem, not yours )
Come on guys, give me your opinion
I'm currently running Hyper NonSense with the default kernel - I think it's Faux that's cooked into the ROM but unsure of this. Between the ROM and the kernel, I'm getting the best battery life I've seen with this phone. Easily have 30-50% left at the end of the day with moderate use; haven't actually benchmarked it more carefully than that.
Any update on this? My sensation doesn't even last a day...
Best kernels right now are Faux kernel
Sebastian FM
Bricked kernel
I myself have found that bricked uses the less battery, but try them yourself and decide which suits your needs.
I'm using Faux right now with HyperNonSense and I would say it's a good balance between battery saving and performance. One thing to keep in mind is that the higher you OC the more juice it'll drain. So far I've always capped my CPU to 1.24Mhz and I've never had an issue with performance. During light use I can get more than 30 hours in a full charge. If it's a moderate use, I'm still able to touch 24 hours. Oh yeah I'm using Anker 1900mAh.
Hello guys,
as for me the most annoying part of a smartphone is running out of battery when there is no chance to recharge, I want to collect your experieces with different roms concerning battery life.
WHich rom gave you the longest battery?
Cheers
There are many factors not only the ROM.
It's the kernel you flashed, it's the settings you have chosen... and at least it's your daily behavior with your phone....
Usually you have a better battery life with custom kernels...

as it was answered
custom kernel with feature as ability to set minimum CPU frequency and probablly voltage control
and U'll have to try some of them in order to find out the wright one
Longest battery life i get with stock rom so far (around 20h with moderate usage)
for custom roms:
Best battery life gave me PAC-Man rom with bubbav4 kernel - which was almost like stock.
ViperOneS had the worst battery life for me.
just try some roms and kernels, it also depends on how you use your phone of course.
in my experience, 4.2.2 roms have the lowest battery life ~3.5 hours screen on + wifi on (active Web surfing) with auto brightness.
Viper rom 2.1 ~4 hours
aosp 4.1.2 (cm10) and viper 1.2.1 ~4.5
very rough numbers obviously so no one roast me. remember I'm talking about total screen on time as reported by the battery app.
The newer jb 4.2 roms are very popular and have a lot of great features, but if battery is your thing, try out some of the older android and sense roms.

For me it was pretty much a tie between Liquid Smooth with Bubba Kernel(OC to 1890 for heavy periods, 1134 for light usage, and complete collapse of the CPU when the screen is off) And Viper One S with the Stock Kernel. Like everyone said though you'll experience wildly different numbers depending on what settings you use and how much
Viper has always had phenomenal battery life.

Complete collapse of Cpu when screen off? Is that pm sleep mode 1 or 0?
Thank you very much. Unfortunately my phone jack is broken so I cannot test your configs, will report after repair though.

There's a setting on through Android Tweaker that gives you the option to control how the phone deep sleeps basically

I realize this device has only been out for a very short time, but are there currently any stable/semi stable kernels that improve battery life? I've looked through a few kernel threads, but many seem to be unstable (which is to be expected) and optimized for overclocking. Are there any kernel developers focusing primarily on battery life?

Stock kernel is fantastic. If you're having issues, we need a BetterBatteryStats log from you.

BBS is not compatible with 4.4 yet. Sven is working on it.
On topic: stock kernel is good. I'm getting excellent battery life, 4+ hours screen on time is no exception. It's a common misconception a custom kernel is a magical battery life extender.

Both faux and franco kernels seems to be maturing fairly well. I can't personally vouch for franco, but I've been stable on every iteration (betas and stable releases) of faux's kernel, with the exception of some aggressive undervolting, which is not a really reflection on the kernel. Battery life has improved, particularly for sleep mode. Can't say the screen on time has improved dramatically, if at all, under these kernels.
FWIW, I have been fortunate enough to have a phone with adequate sound output, so I have not played at all the the sound mods available through faux, only the CPU/GPU/memory settings.

Franco kernel on the N4 gave me 1.5 to 2.5 hrs. extra screenontime compared to stock Thats a fact and no placebo.

I tried all popular kernels on my GNEX. And by trying I don't mean flashing a new one every other day, used them for a couple of weeks at least. None of them produced any noticeable increase in battery life. That's a fact as well. I only used them for their options.
I'm curious what makes people think what the mechanism is behind hours of extra screen on time with a custom kernel (where custom is 95% or more original AOSP code).

Read some Franco N4 pages and you`ll see my statement confirmed. The Gnex (which i only owned for a very brief period) is not the N4.

I've read dozens of people claiming Franco, GlaDOS, Faux, Trinity, etc did wonders for their GNEX battery life. They never did for me, despite I used their recommendations and setup. I've yet to stumble upon actual proof (and I don't mean screen on time screenshots accompanied by opinions of users) a custom kernel actually uses less current than the stock one. If you have some, I'm very curious to read it.

There is a beta version posted on XDA that works with 4.4 http://forum.xda-developers.com/showthread.php?t=1179809
BBS beta has been available in the forum for weeks. It's almost always on the first page, somehow people keep overlooking it.
As far as kernel battery life goes, I think it can matter in certain cases. For instance, I came from the S3, and I don't know about other phones, but the battery life on the CM 3.4 kernel was absolutely terrible (3.0 was fine). Custom kernel was needed not only to tame the battery drain, but to improve stability (fix hotbooting, etc.). Support for that device has been sub par for a long time on the AOSP front. If it weren't for KT747 and leanKernel, CM wouldn't have been usable at all (3.4+). Though, there is still a very valid argument that it wasn't usable anyhow. So custom kernels can make a difference in some cases.
Sleep is an issue with the stock kernel? I get 0.2%-0.4% drain per hour while idling. Zero issues here. If you want proof, I'd be happy to attach a BBS log for you guys to inspect. I don't disable sync or GPS. Never have and never will. You need to be in control of the apps on your phone.
Perhaps I should have clarified: my battery life is actually very good. I don't have any major complaints, and my idle drain is insanely low (the 0.2% - 0.4% figure claimed by Aerowinder isn't too far off). I'm coming from a Note 2 though, so although the battery life is good, I'm always looking for something to make it a bit better . I've been watching Franco and Faux kernels, but they seem hit or miss based on what I'm reading and the personal experience of my friends. I may wait a while longer for a stable release.
Just wondering what kernels are showing best battery?
ElementalX
Best kernel and ROM plzz tell guys as not happy with stock OOS 5.1.8
Franco Kernel works best for me.
Definetly franco kernel in terms of battery life. But everyone have to decide by themselves which kernel is best.
For every different user, every kernel will yield different results.
All i can say atm is that every kernel out there is amazing, stock is better for some users but has less options.
I recommend you to try it out few kernels out there and see what's better for you, as i said earlier its different for every user...
Usage patterns have a far larger impact on battery life than kernels do. A kernel that gives good battery life to someone who is gaming all day and sees 5+ hours of SOT isn't necessarily going to be be best for someone one doing mainly email and messaging with the phone in deep sleep 90% of the time. From what I've seen here, usage patterns are all over the map, so someone else's recommendation isn't likely to be of much use to you.
Just try them all and see what works best.
