Hello,
My main criterion in deciding which of the many custom ROMs to go with is amount of battery life improvement I will have.
I see that the AHRD rom is the most popular, but does it also have the best battery life?
Or will the battery life improvements only occur when the source code is released and the One X runs on an ICS Kernel? I am under the impression that for some strange reason, the One X is running on a gingerbread kernel.
Thanks
This should properbly be in the Q&A section.
But anyway if you want great batterylife you should try Cyanogenmod. Those are the most basic ICS roms. Without any Sense gimmicks to suck the power.
That coupled with the Franco kernel should give you good battery life.
At the moment I'm using insertcoin with bricked kernel. And i have about 30% left at the end of the day. And I'm a fairly heavy user. So I find that to be acceptable.
And sorry if my spelling or grammer sucks, I'm from Denmark, so English is not my first language

Virtually everything that is asked on this board is a question. In fact, the majority of people who visit this board come to get a question answered. So the distinction is odd to me. People ask questions within threads that have declarative sentence titles all the time.
So if I had said "AHRD ROM gives insane battery life" then I guess it belongs in the general forum. Then if someone replies that Chameleon does even better as post #2, and I reply, why is it so much better as post #3. Then I have asked a question. My point is that in every thread there are questions, whether it's post #1 or post #3 seems like an arbitrary distinction. The fact that the Q&A section is not growing very quickly suggests confusion, since I still believe that if you analyzed the content of each post, and dare I say the overarching purpose of the board, is to ask questions. Newbies also see that he Q&A section isn't nearly as well frequented, so they post in the general section.
I think that the Q&A forum and the FAQ overlap in purpose. Anyway, just my 2 cents.
Thank you though for the answers to my question. I had expected, given the Anandtech review, that the One X would have comparable battery life to the iphone 4. However, I am finding this to be anything but the case, and I recently installed AHRD (wiped battery stats, etc). When trying to run down the battery (max brightness at 550 nits and surfing over 3g), I'm dead in 2 hours. My 2 yr-old iphone 4,with a peak brightness of about 500 nits, lasts approximately twice as long under identical conditions. I am finding the One X no better than the HTC Amaze, which has notoriously poor battery life. On the positive side, the One X's battery life is not as bad as the original EVO 4G, and the One X's standby battery drain is extremely low. I shudder to think what the battery life would be like if I had a US version which has LTE.
I have not noticed any improvements with any custom ROM thus far, but it's possible that using the screen at 75% brightness is basically such a determining factor that any gains in battery life are imperceptible to me. If someone can confirm that it is possible to drain the battery if you surfed at max brightness for 3 hours continuously and that that's just the state of phones today, then I can accept that. I just want to make sure that my phone is behaving normally and that any battery tweaks, cpu undervolting, wont' make a huge difference.

None of the custom ROMs change anything to do with battery consumption. A custom kernel could help, however I have tried them all and none of them make any appreciable difference.
Browsing over 3G seems to kill battery fast, I have never been able to get more than 3 hours screen time, and most of the time it is 2 or 2 and a half hours.
Hi thanks alot for the reply. I was thought that custom ROMs were supposed to improve battery life (one of the major reasons, if not the major reason, to install a custom ROM). In fact, in most of the intros for ROMs, they say something like "excellent battery life".
But you're saying that it is at the kernel level where improvements in battery life are made?
I agree with your conclusions--each custom ROM is about the same regarding battery life, and it is possible to surf and kill the phone in 3 hours of screen time, if I want my max brightness glory and over 3g.
Hi
Im going to summer camp and I can be long time without power. So I need best rom, kernel, and maybe radio for my Desire hd. I need rom with camera. Plz tell me wich compilaton have best battery life.
My 1st post, sorry for my bad english
In before someone scolds you for not searching
Radio is subjective to area.
A rom with great battery life without changing anything could be either black ice or gb rd miui. Both are close in battery life, and from all the roms miui has the best cam in my opinion.
Unless you are willing to buy a cam from the market.
Your best option is to test a few roms out for a few days. Get additional batteries cause no rom will go beyond a day with heavy use. On standby you would get two days, maybe more.
Edit: however I've seen some screenshots here and there of people with crazy bat stats. A few, but there are a few.
You can also look into v6 supercharger, there may be something there for you.
Sent from a dream.
I use Cyanogenmod 7.2.0-RC2 with LordModUE 8.9b7-CFS kernel, and it has a really great battery life.
My radio is 12.65.60.29U_26.14.04.28_M
I have set cpu governer to smartassv2, with min frequence to 122MHz and max to 1152MHz.
With these settings, the ROM runs smoothly without any lag, and I get about 24h of battery life if I use the phone normally: music (2h), call (1h), internet (?), GPS+Endomondo app (~1h30), Wifi (1h)
Which rom is the best [for battery life] between these one??
- cyanogenmod
- miui
- stock ics
All with the ultima kernel from riyal.

For me its KA21 with Arcknight 3.3 Stock Kernel.
Really smooth, better battery than i experienced stockwise...
try ICS_anzu_KTG tuned_V1.41: governor interactiv
actually battery drain more depends on the kernels..for best battery life stock kernel is the best
Guys note that lad has Pro not Arc. Stock is usually the worst, or better - default gauge for custom ROMs. I've been watching cyanogenmod discussion for a while, usually users feedback on battery life varied from version to version; for tweaked versions can be said that battery life is the same as in stock while the performance is 20% better. I don't know about MIUI.
(Out of your question, the best for battery life are Ultima ROM and Buttermilk ROM which are optimized for battery life and battery life is notably better there; with Buttermilk and low usage you can do as much as 4 days without charging - worth for outdoor trips. Ultima ROM when idle eats like 0,6% per hour.)
Stock rom with stock kernal had the best battery life... but also lags the most.
I recomend arconium ICS with stock kernal for a balaced experiance...!!!

Well if you game a lot compared to someone who doesn't then obviously ones battery will last longer than the other, so there's a few factors that can be taken into account in regards to battery life.

well my method of testing battery drain(i guess everybody tests the same way) is only on standby..how much time does it take to move 1% down when the phone is not touched for an hr or 2...in exceptional cases battery will drain fast while using 3G in one kernel but lil slow on other kernel..
again my point is kernel is more responsible for battery life of the phone rather than a ROM..

Then you need to take syncing into account, if yours is on and mine is off on the same kernel then yours may drian a bit quicker than mine, which goes back to my point of how a user uses their Phone. I don't think it's a black and white issue.

yea dude.. i get it..my point was simple..people were talking about best roms for battery life.. i just said kernel plays an important role in deciding that..that was my only point..i wasnt arguing with anyone..and testing of battery drain at standby means with data off,bluetooth off, gps off..hence syncing of account wont come into picture
I'm not arguing, just trying to make a point also.

Yes I know and sorry, the last two ROMs I was refering to are GB. However, Riyal is working on Ultima ICS ROM and it already exists in alpha version! See this post with download link Hopefully the ROM will have similar advantages as has GB Ultima ROM over GB stock ROM, which means better battery life, better wi-fi reception, improved camera and so on.

I did that when I had iPhone 4.
im using cm7.2 latest release alvays, i also have an app set cpu and i set my governor to scary, min freq 145 mhz, and max 1024, and im using profiles for apps that im using most of time (underclock cpu while using that apps)
with that i have at least 40% better battery life
and, yes, u can downgrade using flashtool

So far Arcknight kernel has quite the reputation for good battery life. IMO, for roms i find CM9 from FreeXperia project quite awesome but then there's an issue with the battery stats and brightness for now so wait for the next release i guess. for GB try arconium 8.2. still mostly its based on kernel and also the governor.

Hey friend, how do you do that? I dont ahve that option.
I remember i had on my other phone.
Im running the newest version. Should I change my device??
What option are you referring to?
I know alot of people ask which is the best combi, but i dont care about that.
im wondering which one really affects the battery more, the rom or the kernel?
im looking for more battery life and i constantly try many roms and kernels to find the best, but its all very erratic so im wondering which one i should change and look for increase in battery life more
tks

99% of the time it'll be the kernel that changes your battery life (exception being if you're running a poorly written ROM, which is unlikely). Kernels give you the ability to tweak your phone for better performance or better battery or any combination of the two, whereas ROMs more or less just change the user interface. I have gotten pretty good battery life on Tiny's kernel, so you could try that, but you could ask 20 people, and you'll get 20 different answers for the best kernel haha
Yep its said kernel affects battery. My experience over a multitude of android devices says neither have a noticeable effect on battery life. I flash kernels for other reasons, not battery life. I've always gotten similar battery life on stock setup vs any combination of ROM/kernel. Maybe SLIGHTLY less battery if the kernel was geared for performance, but never have I seen a noticeable increase in life.

Biggest battery draw is going to be the one you didn't mention. Apps. Specifically the ones that run in background syncing data all the time. Try a little experiment by going to your mobile data usage, setting a limit and then disabling background data and auto sync. You'd be surprised how much battery Google now sucks down

I see these terms a lot when kernels are being discussed to save battery life, can these two be used together? What are the differences? Thanks in advance for any information.

You really can't compare these to but.
AKT basically is changing kernel tunables in such matter that it saves battery or increases peformance depending on which the profile is ment for.. The problem is that everyone has a different usage pattern and everyone's definition of smooth and battery is different... For some Project Zhana can be really efficient and smooth while for me it is efficient/battery friendly but not as smooth.
EAS basically replaces the whole HMP part which almost every device runs now (HMP). EAS is quite new and quite experimental but really stable, you really won't notice it is experimental. EAS is a bit hard to explain for me. But if you are looking for a good user experience and the best battery life with it I would suggest you trying VertexOS.
Now correct me if I'm wrong I'm not a ****ing genius at this!

Awesome! Thank you very much for the info, I understand it much better now
In my experience, I get better battery life a balanced profile on AKT (fusion balanced) on OOS. But performance is amazing on Vertex! And battery life isn't terrible, although not as good as on OOS, and it is still very usable.

Thanks for the insight! I currently have the official Resurrection Remix ROM for my 3T with the latest EX kernel. Battery has been inconsistent for me even with the Wakelocks blocked and a mainly black theme, but I think it has to do with the weaker signal as opposed to OOS. I assume there is a way to apply these AKT profiles in the EX kernel app and have them apply after every reboot? I would prefer to stay with Ressurection over Vertex because it already has almost every feature available, and it would be much more convenient than flashing a different ROM each time for a new feature I wanted lol (since there is no Xposed for nougat)

See the link posted by @juliusedward.
ELI5: Basically, EAS and HMP are way to manage tasks in a multi-core processor. HMP requires a lot a guess work and experience to get it right. EAS is, Well, smart! It gets cpu utilization and load information using WALT/PELT (it's a new topic entirely. Think of them like a function, which they honestly are.) and decides which core is perfectly suited for the current given task and at what frequency. So, it is in it's nature to be more efficient and more battery friendly. Although, through lots of tweaking and optimization in HMP kernels it's not that bad either.
I run VertexOS.
EAS seems offer better battery life, same smoothness, and less warm !

Try Blu spark kernel. It's my favorite kernel in terms of performance and battery life. I can get 6-7hrs screen on time consistently over 24 hours on LTE and wifi. Performance is butter smooth. And when I mean butter smooth, I mean no frame drops, no microstutters, pure 60fps smoothness. Something not a single AKT profile can provide without destroying the battery life so I wouldn't recommend them, and yes I've tried every single profile. FlashKernel is also a really nice kernel but you need to tweak the stock governor settings to get nice performance.
Haven't tried EAS, but supposedly it does its job well, very well so you can also try that out. Try vertex it has been getting high praises.

I think it is safe to presume that it answers your question to a great considerable extent.
Hope it helps.

P.S. AKT profiles cannot be applied on EAS, not yet.

Dont blame the kernel if you have standby drain.
I also use bluspark with freedomos ce and i nearly have zero battery drain over night.
If you have too much standby drain its some third party apps, services or something that keeps your phone awake.
