Which ROM&Kernel Combination gave you the best battery life?
I have to improve my battery life and i can't find the right combination.
trial and error, each kernal/rom is different for everyone

pretty much. every device behaves differently I found.
Whatever combination you try though make sure you give it 2-3 days before judging it.
For me I'm using speedmod kernel + CheckRom HD. It's a great balance between battery life and performance. I use the 2000 mAh samsung battery and never have to worry during the day about my battery. Just plug it in when I go to sleep.
All the best!
I think Sensation ROM is the best. Cuz, very long battery life about 3-4 days in normal use(without open 3g or wifi). And, very stable for me

You're going to have to try various combinations out for yourself. Using the same combination as someone else on the basis of them saying "This rom/kernel combination gives me teh awesomz battery life !" will almost certainly lead to you being disappointed.
The reasons for that are:- No two phones come out of the factory the same (components do vary, mostly slightly, sometimes a lot), no two users will have the same usage patterns and no two users will have their phones setup the same.
Sooo....Get reading. Read the various threads about the various roms/kernels, take particular note of other people's experiences with same to give you a guide. And ask questions there if necessary.
Asking vague questions like this will ultimately waste your time.
Edit - Notice how so far you've only had answers from "newer" forum members ? There's a reason for that. Read my post again, the hint's in there

+1 on this.
I have no battery complaints. Why???? Because I have 3 spare batteries. I advise anyone who has issues with battery life to do the same.

My phone lasts weeks if I don't touch it and leave it in airplane mode! Wooooo!
There's a new "what ROM/kernel thread" every couple of days and I always read them for some reason. I think I have a pathological need to get these things marked as read but I don't want to just click the "Mark This Forum Read" button.
Really, every ROM I've used gets me through at least one day of normal use, and my varying usage patterns have much, much more impact than ROM. My advice is one of two things: either use a ROM you're comfortable with and just don't mess with it too much, or develop ORD and flash ROMs every few days. Either way you're probably gonna be fine.
CheckROM v4 and SiyahKernel i get just over a day of constant use, and around 3 to 4 days of moderate use using standard battery and a few battery saving tips mentioned previously.
CM7 + siyah kernel
so far i've been using CM7 + siyah kernel and it can last me a day with moderate use...just use 2G instead of 3G if u r not using the internet..2G is more than enough for my background apps that needs data for push notification(ie facebook,mail,whatsapp etc...)

Due to the overwhelming amount of posts in many Rom threads, it is quite difficult even with the search option to find what you are looking for. As many of us who visit XDA on a daily basis realize, a large number of these posts are very repetitive. "Which kernel should I use for the best battery life?" "What Kernel will be the smoothest on my phone?" "Oh you have (Insert Kernel Here) Kernel, what kinda of battery life are you getting?" The questions in regards to battery life, kernels, and performance go on and on. I came up with an idea for a thread and after talking to a MOD about it decided to go ahead and get it started.
The Purpose of this Thread:
-Compile fellow EVO user's experiences with certain Rom and Kernel setup's in order to help all of us get the best performance and battery life with our EVO.
-To help cut down on the amount of repetitive posting about Kernels, Battery Life, and SetCpu in Rom threads. This is a forum and it is about makings posts, but many times people end up posting questions related to these things that have already been answered but may be hard to find.
-To give members a central thread for optimal performance based on other users experiences.
-To help other members find what Kernels, SetCPU settings, and other options will work best based upon their Hardware version.**I bring the hardware version up because it seems like certain things I.E. Kernels and certain settings do not play well with certain Hardware versions of the Evo.**
-To provide an Informational thread based on your experiences to help out everyone.
Please Note:
-This thread is NOT a place to go to war with others over which Rom is best or to bad mouth other Roms, everyone has their own preferences remember that.
-In order to keep this thread as clean and productive as possible, PLEASE REFRAIN FROM ASKING QUESTIONS HERE!
-If you have a question for an individual, PM them.
-If you have a question in regards to a Kernel, refer to the kernels thread.
-If you have a question in regards to SetCPU use the Q&A or your roms thread.
-If there is a basic question that often comes up on the Evo forums I will try to
provide links to the information.
-This thread is to be NON BIASED.
**My hopes would be that enough members post their personal stats and info here that on an OP I can list each rom, the hardware versions of the phone and what set ups seem to work the best with them. This info would be based on a general consensus based upon the information posted here.**
What to Post:
-Rom and Rom version that you are using. (I.E. Myn's Warm TwoPointTwo RLS 4) PLEASE make the font for this RED so users can easily spot which rom you are on when looking through this thread.
-Current Software version on your phone. (I.E. 3.30.651.3)
-Hardware version of your phone. (0001,0002,0003 or 0004) Please make this RED also.
-This is found under: Settings>About Phone>Hardware Information.
-The Kernel that you are using, the full name. (I.E. netarchy-toastmod-4.2.1-cfs-bfq-havs-more-smartass-universal)
-SetCPU? If so, what kind of settings are you using?
-Any kind of battery tweak? (I.E. Colin pH method)
-How would you rate your usage, and what is you awake time? (I.E. Minimal, Moderate, Heavy)(Awake Time:Settings>Battery)
-On a day to day basis what do you use your phone for?
-What kind of battery life are you getting? (On full charge: I.E. 16 hours)
-The Pros/Cons of this setup. (Cons if there are any)
-Why you would recommend this set up to others? (Again, please do not use this to slander other roms)
If you choose to contribute to this thread, Thank you for reading through this and for your contribution. I think if we can make something of this thread we can all benefit a lot from it. If you have any suggestions on what I should add to this please feel free to post it with your info or PM me if your not posting. I will try to update as much as possible, and of course that will depend on the reply that I get.
Reserved for future use
I would state the awake time instead of asking if they are a moderate/heavy...seems less opinionated even though someone with 5 hours awake time with idle cpu is not the same as 3 hours under heavy load.

Thank you sir, I went ahead and just added it in with it. Then we get the idea from both ways. If you have anything else just let me know. I would appreciate it!
i think you should post what kind of battery you are using
is it the standard 1500 mAH battery or the other extended battery
so people won't get lost
This is a good place to start, but it's difficult to get a good idea because there are too many variables that affect battery life from user to user. In addition, my light usage could be your moderate. Then people run different programs which will affect identical setups. Just throwing these things out there if you wonder why you aren't getting the same battery life as someone with same setup.
I'll go first....
I actually think this is an awesome idea. I think the idea of "not every phone is created equally" is a little over-exaggerated with the evo. Maybe we can start finding some similarities.
Myn's Warm TwoPointTwo RLS 4
3.30.651.3
0003
HTC Kernel #17. (I also tried the King's #11 (i think) and got horrible battery drain!)
Not using SetCPU
No Battery tweaks
Moderate usage. Not sure on awake time. I will edit this later today to add.
Mostly phone calls. A couple of texts and emails. Some games while I'm on the throne. The occasional web search.
I get maybe 12-14 hours of battery life.
PRO's:
-it's pretty looking
-a themed rosie launcher.
CON's:
-I got better battery life with Fresh 3.4.0.1 and stock kernel.
-Doesn't offer the original HTC #11 kernel like Fresh does. Anyone have a link to it?
I would recommend this setup to anyone that wants a good looking rom that has lots of customization options. I use it mostly because of the look of it. But, it is quick, scores well on quadrant, and gets decent battery life... It is not the best I have found... but it will get you through most of a day on moderate usage.
---
Can someone tell me... does the battery life depend on how the kernel plays with the ROM? I could get about 20-24 hours of battery life on Fresh with kernel #11. Now that I'm on Myn's and I could find the #11 kernel again, would I get the same battery life?
Good point. One of my biggest goals is to help people who wish to flash a custom kernel find the right one that is friendly with the Rom and most importantly the hardware version. Imo a rather a kernel is going to work with a phone or not has to do a lot with the hardware.

Iv always considered battery life a very important factor in my purchasing of a phone and was one of the big reasons i moved from my Desire HD to the Nexus S (amongst many others). However having been on the android scene for a while im used to tinkering with kernels and roms etc and due to the new battery graph in gingerbread im now able to make direct comparisons rom by rom and kernel by kernel to see how they all differ. This is all shown + explained below.
First id like to explain my method;
I install the rom and kernel with the same apps I always use and charge the phone fully until i am about to go to sleep. I then unplug the phone and leave it in the exactly the same place on my desk with exactly the same settings (sync intervals etc) and i kill all apps before i leave it just to make sure the test is fair.
In the morning i then take a screen shot of the battery life over the period of usually 8 hours and will upload this for you to see. I then look at the over-night battery drain as a comparison on how good battery life is on specific roms and kernels.
Justification - Many of you may be thinking who cares about standby battery life? I care about the battery when im using it!?
Well although that's valid there are many reasons i have taken this approach;
1. It is completely fair i.e. no individual differences such as 'im a heavy user' but we all have different definitions of a 'heavy user'. This is eliminated by the fact the phone is not used and thus the same every time (no individual differences)
2. If a phone has severe battery drain during sleep general knowledge should dictate that battery drain should increase when the screen is on, cpu is working and your syncing your facebook wall, thus a direct correlation with sleep battery drain and usage drain should be apparent.
Therefore i have decided over the next few days/weeks etc i will upload on a regular basis a screenshot of the battery drain over night, along with the battery use details and screen on time etc etc. In addition to the rom and kernel info and i hope that over time this proves to be a very useful thread.
I have been doing this over the last few days on a less strict system and there have been some VERY interesting results which i will upload over the next few days.
(Just a final note iv never really done anything like this on xda before so if its a stupid idea then please tell me now so i dont waste my time doing it, however if people are really interested please let me know and il make sure i do my best!!)
Thanks for reading my extremely long post!

SCREENSHOT 1: This was using modacos custom rom r10 and the kernel that comes with it, i had quite a short sleep (about 6 hours) but the curve pretty much shows what the point im trying to make is. The battery life is great!!
SCREENSHOT 2: This is CM7 Nightly build 27# with Netarchy's latest 1.2.1 kernel and although i didnt use the screen once of charge for a few minutes as you can see once the screen was off battery life barely decreased and was over a long period of time.
If anyone wants me to test specific combos please let me know.
I'm actually looking forward to reading your results.

I'd be interested in seeing CM7, just whatever nightly build you manage to catch.
I don't think that result will give you precise result.
I found that statistic is wrong sometimes.
It is better to measure using "play video loop".
So, find a movie, set to the same brightness and play in loop?

Unfortunately that will not give you how well the rom does while it is idle.
I'm really looking forward to your results. My only issue with this phone is the battery life is terrible. I ordered an extended battery off Ebay 3 weeks ago and have yet to receive it. Never ordering anything from Hong Kong again!

What were you using before that you consider this phone to have bad battery life? By far this phone has the best battery life of any Android device I've owned. If you want bad battery life, get an Evo. That is horrific battery life.

I am looking forward to the rest of these, however just a quick question. What was your battery use like in that situation with the stock ROM? Just for reference, because I'm thinking I might switch to modaco soon. Thanks!
More soon
Iv got a few more screenies but it seems i may have to end this thread prematurely. Its the SNS or 2.3 but idle battery usage for me is pretty much identical no matter what the kernel or rom (il upload a CM7 + Netarchy 1.2.1 shot top op). This was unexpected on my behalf because with my DHD kernels and roms had a big impact on idle battery consumption. I have noticed however that without a full wipe when changing some kernels such as with M r10 idle battery life can increase drastically. I will continue for the next few days and if i dont see any big changes i may move method to a video loop or something of the sort.
Interesting find
I found out something today that may interest may of you. I was messing around with the sleep profiles on SetCpu with netarchys kernel and i found that its better to leave the range from 100-800 than 100-400 or less. This i believe is because when the phone is asleep and carries out a process it will be forced to clock to the maximum of 400mhz and then stay at that speed for 10 seconds, instead of say going up to 800mhz for 1-2 seconds to complete the same process. So a tip to you would be set your profile to 100-800mhz conservative and see what you get!

This kinda enforces the point that SetCPU is useless for the NS unless you really want to overclock...
Any battery saving tactics used buy lowering screen off profiles are counteracted by the system process;( So i think in the context of battery life you are probably better to not use SetCPU

I would definitely move to a video loop or some other 'heavy use' task because when you think about it, not too much can really be changed when almost no power is being used in the first place.
You could also just mention your general feeling for the battery life of each rom, because quite often that is what I go by as my usage varies depending on a range of things (school day or weekend etc) .

for your information, all testing start around 7:17 AM (off charger) and at screen shot at 10:00 PM...
and if you want to test a specific setting, please tell me. i'll be glad to test it out for you.
Thanks.
This will tell you what is best for your particular phone and your usage habits, but the results won't be gospel.
If you're trying to determine how much each variable affects battery consumption, you should change just one setting at a time in conjunction with a design of experiments.

for that one test different roms and kernels, whether also I liked the mine that is looked nice but also the trinity kernel is pretty good... the battery last much more but also the performance a little low.
I used to be super-anal about battery conservation and kept pretty specific notes. I'll see if I can dig them up, but they're all for Evo 4G roms/kernels.
I've since learned to relax a little and just use the crap out of my phone. No more eeking out every last mA lol.

I use the Faux Ultimate Kernel, and I simply under clock it when I want more battery life. I've managed to get almost a week out of it with moderate use, while being under clocked.

There is no "best" kernel or rom, They're opinions and subjective as it depends on your apps, usage and settings which is why these type of "best" or "fave" topics are not allowed on XDA.

Maybe I got the title wrong. I just would like to hear experiences on battery life with kernels. That's it. I don't have time to try kernels at the moment :/

If you don't have time to experiment, then pick and Kernel which supports under clocking and under clock it for more battery life. That should help a little bit.
But like TheATHEiST said, there is no best, only preference.

True... but I don't think the OP was looking for 'best'... just garnering opinion on 'optimum'...(which I suppose might be regarded as semantic hair splitting; and so perhaps this should have been posted in 'General' instead of 'Q & A').
And in any case, if such threads aren't allowed, then this http://forum.xda-developers.com/showthread.php?t=2151963 is in serious breach of the rules.

Ok Folks, you all know the rules about Best/Favorite Roms and Kernels and such. Not allowed due to flame wars sometimes starting.
Roms and Kernels are personal opinions, and what works best on 1 device, may behave differently on another. This is the way it is. The best method, is to read the kernel threads, and try a couple different ones.
The following thread, is the only OFFICIAL thread sanctioned by the Moderators. Please post your questions there, so that we may keep the forum cleaner for better searches.

There is really nothing one size fits all kind of thing. Try these different ROMs for yourself to see what works best for you. It's hard to see which has better battery life since different users will have different usage stats.
I have to agree... One person might get great battery on RR and terrible on AICP, the next person the opposite. The only to really tell which one gets the best battery in your situation is to try them.
Data is too scattered to determine which ROM provides the best battery life. You see people getting all day battery life with different kernels, tweaks, usage, etc

I'm not trying to bash your post but TBH, any comparison you make from others is practically useless. As mentioned, people have different experiences on custom ROMs. One specific ROM might have excellent battery life on one phone and have horrible battery life on another of the same model. But there is an even more important factor that makes comparing across ROMs just as useless... Everyone uses their phone differently. Not just with apps they install, but with the features of a ROM they they decide to enable or not.
On that note, if you are considering a custom ROM, the best way to determine if it is right for you is simply to try them. Make backups that way you can revert back to the one you decide is best.
I know that every user use their phone differently. I don't know what made you guys think i don't know that. But what i am trying to compare is not overall battery life but battery life based on individual usage. Like when some one use that rom for only calls and get a lot of stand by time how much battery it drains. from that i can know how much battery it drains when kept idle. Same goes for using wifi or using mobile data , watching YouTube or reading PDF. I want to know how much battery that rom uses on what usage.
Sorry for my bad English. I hope you guys can understand what i am trying to say.

I understand this. But I think it would be easier to try for yourself, because to get say, me to try say 4 different ROMs, same usage, and then report back to you would be more time consuming than you trying for yourself.
I know you know that every user is different but the same user trying different ROMs for you just doesn't make sense.

Referencing individual usage as you have, along with any specific ROM across devices, you are not going to get consistent results. I understand you are trying to consolidate this data on one post, but there are to many variables involved.
To highlight: I could run AICP on my XT1575 with a clean install and no extra apps installed and make only calls and I might get excellent battery life on standby. But another XT1575 owner can do the exact same setup, make the same number and times of calls and get horrible battery life. This pretty much goes for any custom ROM, especially those not based on stock. This does not even account for differences in MM vs N. This also does not account for an update to a ROM screwing up battery life and the next one may fix it (which is relatively common). I've even seen where someone gets great battery life up to a certain update and thereafter it sucks, but another can experience the opposite.
And once again, individual usage still matters as individuals will have different apps installed, which can take up varying amounts of battery depending on background processes and syncing. This affects standby time and SOT to some degree. Also do not forget that the chipset on this phone is prone to negative affects on battery depending on cell signal strength, so that is another kink in observing and comparing battery life across users.
Ultimately, the best way to determine what gives you the best battery life is too rest ROMs for yourself and your specific usages.

I am not saying anyone to try different roms for me. I was just wanting them to post battery stat of the rom they use as their daily driver.

Yes ok. So we should be on the same page about different users using their devices differently. So if user A posts about say ROM B, and user B posts about ROM A, you know you can't compare. I would post my stats with RR but you couldn't compare to someone posting AICP stats as we are different users. The only way to be even somewhat accurate would be to get the same user to try different ROMs. Which you can do. Honestly just try the different ROMs! I will say with my experience though DU has not had the greatest battery life.

Well said!
@yk1999 As stated above as well as in my post, you just can't compare experiences of users across multiple devices and ROMs as there are to many variables involved. We understand what you are asking and we are telling you that there is only one way for you to get the information you are looking for. The only way for you to figure out what will have the best battery life in YOUR situation (how a ROM operates on YOUR specific device, YOUR selection of apps, and YOUR specific usage scenarios) is to test the ROMs for yourself.
Maybe there should be an app saving battery stats for the current ROM (internal storage or personal cloud), and comparing these personal stats with previous stats made when you had another ROM installed.
Of course there are other variables that affect the battery stats (like the apps installed, or the apps you actually open in a battery cycle) but at least the app would be able to list and compare battery stats on the same device and user.
Ie, I imagine a list like:
- ROM R1. Kernel K1. X1 apps installed. Battery rate: BR1
- ROM R1. Kernel K2. X1 apps installed. Battery rate: BR2
- ROM R2. Kernel K1. X1 apps installed. Battery rate: BR3
...
It could be able to group by Android version,...
I haven't found an app doing this. Do you know an app doing it? And, do you think this app would make any sense?
