[Q] HTC EVO -- Best Battery life ROM???

Can anyone tell me which ROM (STABLE) provides the best battery life on HTC EVO???
Thanks!

I have been through just about all on this site and Fresh's newest seems to work best for me. With moderate daily usage I can go without charging for about 22-24 hours. Of course all I need to go is 12-14 b/c I charge every night anyway, but I did leave off charger one day just to see how far I could go. I'm giving Calk's latest a try right now to see how it goes. Just be sure to give whatever ROM you try a couple charges before making a final decision, as it usually takes this amount to get an accurate read on true battery life.

how many of these post are we going to need lol

I know that the latest kernels off the latest build have been killing my battery, it's horrible for my EVO.
But you really have to try different rom/kernel/PRI/radio combinations to find the best battery life for your Evo. I wish there was a preset rating system for each rom though, just to see how things work for everyone else(i.e. battery life, quadrant scores, force close problems, etc.)...but there really are a lot of variables, so I don't think that may ever happen.

Yeah I agree there isn't a clear cut winner. Everyone uses their phone different so it will differ for everyone.
Totally agree to give it a few full charges... I suggest when you get a new rom and/or kernel installed to reset the battery stats (can be done in recovery) then use it till it dies then charge to full before turning it back on.
Personally, I've been using Fresh 3.3 w/ the Kings #6 kernel and not only has the phone been screamin' fast the battery has been good. I'm only on my 2nd charge up though so I still have one or two to go before everything smooths out.

As posted here, the tests showed that CM w/ Snap 7.5 probably has the best battery life - and it seems by a lot.

I'm using the latest Fresh and I just plugged my phone in at 15% battery after 37 hours. I'm pretty happy with that.

Fresh Rom always gave me good battery.. I'm just using the rooted stock OTA and am getting great battery life.

I think it would be a great idea for this kind of stuff to happen. Some aggregated source where everyone can submit their information using various roms, kernels, etc. Whether it be information regarding Quadrant scores, linpacks or battery life. On computer hardware forums they generally have a section dedicated to OCing records with charts listing someones entire setup while attaining the clock speeds. I don't see why a similar implementation can not be done here.

i use Fresh's Rom made my battery life live avg abt 15 hours

Over 40 kernels were tested and benchmarked in 7 different ways, and the results are posted here.
Should tell you everything you want to know, without bringing roms into the picture (since battery life is most affected by the kernel used, not the rom)
edit - looks like I'm a bit late withthat link - I see the thread for that site was already posted above. It's a great resource.

Fresh 3.2, hands down best battery life for me. 3.3 was pretty bad, as was myn's release....which sucks, because myn's rom is otherwise awesome.

I am using Fresh 3.3.0.1 with a baked kernel that is able to over clock. I then have SetCPU installed with profiles for different states of the phone. If my screen is off I have the cpu set to a max of 500MHz to save battery if there are any processes running in the background. I then have my cpu set to 1119MHz when the phone is plugged in or at 100% with the screen on just because I like a snappy phone. Then when the battery drops below 50% I have it return to stock speeds.
I use my phone heavily for things like subsonic, QIK, FB, Calendar, wireless tether, and of course since unlimited data, calling to any cell, and texting I am on it a lot keeping in touch with friends. I also use the sprint nav at least twice a week.
Results will vary from user to user but so far the phone has been on 7 hours and after some moderate use it's only down to around 75% on the battery.
Again this is how I MYSELF use my phone with this rom and kernel this may not be how you use your phone and you may see different results.
What I have done is searched roms and installed them in total I have used 4 different roms. Baked, Cyanogen, Fresh, and Virus. After installing each rom and setting up my phone I made a nand backup of each so I can flash between them as needed to test. I have found out of all of these roms Fresh 3.3.0.1 with a kernel from the baked roms has worked the best for MY daily use.

Do Differnt Kernels Really Help Your Battery Life?

I've had my G2 since last year of early December. The first week I had it, I didn't root it because I wanted to see what kind of battery life I was going to get out. Heavy useage no matter what I seem to do I would get. 15 to 18 hours. Calling, texting, web, youtube, & games. If I didn't use the phone that much I would get over a day which would shock me. What I'm trying get at is do differnt kerenls really help your battery life? I've seen many people claiming this and differnt people got differnt results because of useage. What do you think post below.

YES.
I with the stock rom and light to no usage I would get about 8 hours. With continuous usage, probably just over an hour. With pershoot's undervolted kernel and CM7, I can get about 12 hours, and just about 4-5 hours heavy usage.
I really wish I could get these amazing battery lifes (lol) that everyone else seems to be getting, but it seems that I'll just have to deal with it because I live in a place with pretty much no signal.

Battery life poor except for stock

I give up.every ROM I run just doesn't have the battery life expected. Am I expecting to much? Not even Cauks or blazer el29 doesn't give the battery life as stock.don't get me wrong they are all great roms but at least for my device not battery friendly. I'll post some battery stats from BBS if anybody has some free time to see what's going on. I'm on Cauks el29 now.I format everything before flashing and I use cauks format all many times. I'm on the verge of staying on stock roll my eyes.

Well when is the last time you used stock? And if it's been quite a while...consider having your battery checked out. Anyway, I'll continue as if your battery is fine from here on out. Basically, anything but stock tends to have a modified kernel. Even with all the battery tweaks, etc out there, there's a chance that the kernel itself might not play well with your phone. I'm not too versed in that, but I also noticed that the TouchWiz based ICS kernels/ROMs give MUCH better battery life than AOSP based kernels/ROMs such as CM9 and AOKP, etc. This is just basic stuff you might already know, but yeah, just go on and post your battery stats, preferably with a custom rom and a stock rom so we can see the difference and where it lies. Also, I'm running Touched by a Galaxy S3 on my phone and with moderate use (music for maybe a few hours a day, texting, don't really make many calls) I average between 8.5 and 11 hours from 100 to 0. Another thing I'd suggest is download CPU Spy from the Android market, or something similar if you prefer, and post screenshots from that on the custom ROM; the problem with AOSP and certain other GB and TW ICS roms that i've seen is that something prevents the processor from going into deep sleep mode, usually keeping it at 200mhz or higher. Lastly, when you use the custom roms, do you notice the phone getting really hot compared to the stock roms?

I'm assuming you know this but are you letting the battery cycle a few times before passing judgement? I usually spend a week on a rom before I decide if I have good/bad battery life... attached screenie is normal for me with moderate use on mijjhs goodness rom

I always had faster battery drains on ROMs than stock. I see all this awesome battery stats screenshots but noticed they all share one common factor, only 1hrs to 30min screen use. Come on guys why I would want that battery life if to get it I have to barely use the phone makes no sense to me.

Agree, everyone have different experiences, I haven't try that ROM yet, I will test it out later. Have a nice day/night sir.

Sadly I have to agree with OP.
And the previous screenshots at 59% with 1hr, 36 screen on is exactly the issue.
Hard to compare your battery stats with mine since screen on time for my phone will be 4+ hours.
Since there are no standardized testing anyone can do with any rom, any speculation on which rom has better battery life or doesn't is just pure bogus seat of the pants gut feelings.
If there were a standard test that ran like. 5 minutes of mail with 20 mails received, 10 minutes download, 30 mins of playing the exact same video, 13 music tracks of the exact same song all with screen, vibration, brightness, etc all at the exact same level, you could get a real test, but, alas, nobody has a standardized test.
For MY usage, stock clocks in at the same as or better than just about any other rom I've tried, including all the various super scripts out there.
I guess I just overuse my phone!

Things drain battery. This is my test off wifi for the most part using the phone as a phone with average use. Didn't even log in to Google on this one. Just proof that intensive applications, google services, and anything else added after a "factory flash" can manipulate battery life significantly.
Oh, and check out drain when I'm in less than ideal coverage. Noticeable difference. One huge factor to consider when diagnosing battery life.

It really depends on what you're doing with the phone. Obviously having brightness up playing heavy games with Wimax on will kill battery faster than someone on low brightness reading an ebook with wifi on. That said, i agree that I've had better battery life stock than almost all ics roms.

But for my money I use onlychevys version of slimbean and it amazing.

I have one that was a little better I believe I got about 35 hours but I can't find SS right now

battery depends on your usage. I could probably pull 4 days out of aokp but I wouldnt be using the phone very much...

You have barely any screen time! Also...you have something keeping your phone awake....big time! Should check that out! You're battery will last even longer if you get your phone deep sleeping!
I usually get 30 hours or so with around 4 hours screen time ....and really...it doesn't vary much no matter what rom I'm on.
That's with my use anyway. Games will drain your battery quick...also no matter what rom you're on.
I'd say use whatever rom appeals to you...I think drastic battery difference among roms is an urban legend.

I heard about the charger issue. I've gotten in the habit for awhile now of always rebooting after a charge. Haven't had sleep issues on any rom with rebooting after a charge.
I do agree that some roms and kernel are better on the battery....but it seems like a minor increase...not enough to influence my choice in roms anyway. I choose a rom that has what I need it to have, has good support, an active thread with dev active in thread....plus dev track history plays some role....I do tend to stick with certain devs.
For me anyway....my 30 hour average....3 1/2 to 4 1/2 screen time has been consistent on any jb rom I've tried. But hey....others may have different experiences.

My benchmark for best battery is how well the phone sleeps, the lastest AOKP nightly has my phone sleeping better than any other rom I have run. I am also running eugene's dual core sleeper app though I have not tested the build without the sleeper app. screen on battery use is going to be a pig, only an hour or so of difference between roms/kernels...

How much screen time do u get ?

Need some guidance :/

The note 2 is known to be the complete phone even till this day... right? and its outstanding part is the battery... right?
I see many people get 5 hours minimum screen on time with usage more than me! My max is 5 hours if I'm lucky, mainly only 3 and a half hours screen on a day. Ive tried a bunch of different roms but no luck, even stock with UV but nothing :/
Is there a combination of rom and kernel that someone could recommend me to see if it'll help? I prefer AOSP roms but there battery hasnt been the best for me but maybe with UV itll work out better?
Any help is appreciated
Thank you

I believe, TW Roms have better battery life than AOSP ones.(haven't proved it) Additional mods, like Note 3 mods or S5 mods, tend to consume more RAM + Battery 'cause they are designed for phones with higher RAM, so try to avoid them. Root apps like Greenify, freezing some apps using TB, and doing the common saving tips(auto brightness, silent mode, off mobile data, etc.) will also help a lot in battery.
Last thing, batteries also tend to degrade in quality, so sometimes it falls short of its expected length of use.
Hope I help even a little.

Hmm I could be more battery cautious, what rom is designed for battery performance like the meanbean rom but that's not for the international version :/

imho, using aosp on n7100 is not a smart choice. in my experience they have almost the same battery drain as sammy. i tried many roms, now i'm testing revolution hd 23 and with some greenifying everything runs smoother, i have 4% of drain during all the night standby with wifi on, i can't get better on any other rom. i think i'll trust this rom for a while. cheers

Hmm I've tried the android revolution rom and it didn't really suit my usage battery wise. I think I may need a new battery since this one has been going for a while :-/
