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.

Until someone takes the time to make a section that covers the different problems. Battery problems, Battery Problems w/ ROMS, Apps not loading, etc. etc.

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.
My girlfriend has a defy and it'd like to put a custom rom on it.
But I know from experience that they often have a lot of bugs.
What's the best rom that doesn't sacrifice any usability?
Oh, and her gps is absolutely awful, it can't lock onto any satellites.
Swifted from my Atrix.
CyanogenMod7 would definitely have to be the best for performance, the phone becomes much more snappy, and responsive. As far as battery is concerned, I'd say it's going to be the same with any ROM seeing as they all have an absolute ton of processes. You can use SetVSel to change the battery consumption. Definitely CM7 though.
What about the bugs?
Swifted from my Atrix.
i've been using cm7 beta 6 since it came out, and i can tell you, there are only minor bugs, nothing to worry about, the phone is absolutely usable, and very fast. the only thing i'm having problems with is the camera, but afaik that's just me, noone else is having it. try it, if it doesn't work out, you could still try froyo (i recommend 3.4.3-11), that's not bad either
I have been on CM7 for a good week now, and haven't really noticed any bugs to be honest. It's a very solid rom.
Any thoughts on her gps issue?
Also, she really likes the look of MIUI, any thoughts on it?
Swifted from my Atrix.
Cm7 comes with a baseband switcher, so it could potentially fix the GPS issues, not sure about that one though.
MIUI, I have zero experience with it, all I know is that it looks like the iPhone.

i have never used miui either, but i've read somewhere that it's development is based on cm7 by quarx, so it probably has more bugs than cm7. not sure though.
+1 for CM7, both performance and stability. I would recommend using the boot menu overclock and vsel settings in 2nd init. I have always had issues with setvsel, but this has been flawless.
I couldn't recommend miui, even in the htc desire , which has had over 8mths to stabilize, it is still full of bugs. My wife has that phone now with cm7 and it is rock solid.
Barebones 1.51 is quick and stable too, but I would wait until Fritolays does a cm7 mod, cm7 is just too good.
from my experiënce, roms don't realy increase or decrease batterylife. more important is weather you overclock or not.
always calibrate your battery, after installing a new rom, or else you're having battery drain problems in notime.
I think quark's cm7 for now is the most nice rom because it is the only 2.3.3 rom runnung perfectly @ 800 mhz. without too much bugs.
when battery is calibrated you can easily do three days while using internet sometimes or play a little game.
If you don't mind using froyo instead of gingerbread, there are tons of nice roms running perfectly fine. try adlxmod, pays, barebone etc.
i try barebones, pays, MIUI and CM7 the level of battery is similar in 4 roms, i can use intensive for 1 day and when i go to charge the phone have 20%

Now i use China Unicom 2.10, same results. I switched from CN 1.11 - Barebones - CN 2.10. I saw a battery draining with batebones, but i dont know if i should blame barebones or some defectiva app.
China 2.10, is very battery friendly and very stable (Fropyo 2.2.2). i'd recommend it over anything else, it have call recorder integrated in dialer, and data plan manager integrated, so you wont incur in data charges. you may need to change baseband to fit your country with basebandswitcher.
Anyway. calibrating a battery is good once every month, but contrary to belief you will not get better battery life; you will just get better readings about its charge.
Screen + Radios are the ones that drains the most power, CPU undervolt can make difference.
Imagine 2 scenarios.
1: Power user, using phone all the time. whatever you do to conserve energy, screen is gonna take 50% of total battery consumption (Tested and confirmed) Radios are the next, so wireless is better than 3g, and 2g is better than 3g. Cpu is the last, undervolt it to save some energy.
2: Users who use the phone for 1-2hours and keep it in the pocket most of the day. Here is where you are going to get the most energy savings, an undervolting and deep sleeping cpu, in china rom, wireless always on, getting notifications from gmail and social networks, will drain only 0.5% of battery per hour, that is 12% every 24 hours. All of the other roms i tried, drained 1%-2% per hour in standby, which is 24% / 48% a day
My defy is running Pay's Rom V6.0, so far so good. Battery life lasts 2 days with moderate use. The only possible bug I found is that the phone sometimes went dead when playing Fruit Ninja.
I've used 3-4 ROMs and so far CM7 is the one with best performance and battery backup. Max I got from my 2months old defy is here in the screeny:
PS: Using SetVsel([email protected],[email protected],[email protected])and I've almost disabled all those eyecandy features of CM7 such as zoom effects on drawer open/close,animate when screen off, ALL vibrations.
My friend has a G2 but no xda account so he asked me to come here and ask you guys what's the best G2 ROM with great battery. Were going on a 14 hour trip and were going need it too last. Any advice? On ROM and kernels
Sent from my HTC Glacier using XDA App
It depends on what you will be doing with it. Any ROM can be made to last 14 hours if you have a battery in good condition and only use it occasionally to check e-mail, visit a few web sites, etc. My Desire Z easily holds up to a full day that way. OTOH, if you're playing games all day long or watching 14 hours of movies, then no ROM will help. You will need an extended battery at that point, or some other way of recharging the battery.
In my experience, although people make claims about how good one ROMs battery life is over another, I have yet to see any convincing evidence. People's usage patterns and phone environment are far too different to be able to say that one particular ROM makes a consistent, noticeable difference. If anyone has actually published scientific results studying this, please point me to them.
As almost all ROMs are derived from a common code base and run on the same hardware, I would focus more on a ROMs usability, speed, feature mix and stability.
+1 to the post above. It is all predicated on how you use your phone and for what, also if you use setCPU or use the tweaKr script (like me), it depends on your profiles and governors. I personally have great battery life using the latest meXdroidMod release for the G2, but I'm very careful to always calibrate my battery between flashing roms. MeXdroidMod is the only one to my knowledge that uses waydownsouth's tweaKr script that allows you to undervolt your processor and set profiles for your CPU that react much faster than setCPU does. My advice is find a rom that you like and make sure to wipe battery stats then use the battery calibration app. Good luck and happy flashing!

Any sense based rom like Unity will be processor intensive, so I don't think it would last nearly as long as an ASOP build. Also the unity dev team has pulled all their download links from xda and their website, so unless you find someone willing to share I don't think you'll have much luck.

I have unity 3.0. I get about 10-12 hours of battery life. Here are some ideas that i use:
-download juice defender
-set max sleep cpu speeds at 368mhz
-processor is set to 1.2 ghz by default. Set it to 800mhz

Exactly. I guess this is where YMMV definitely comes in handy. All the ROMs I've used I can easily get more than half a day out of them with my daily use. I shut off data when at work and turn it on on my breaks to browse the web, check emails etc.
There is the G-Lite rom from the Virtuous guys. I haven't tried it out but the other roms I've used from them are great. It's not Sense tho, it's ASOP.
http://forum.xda-developers.com/showthread.php?t=1076786
+1 for G-Lite rom. With version 1.0.2. i could consistently get 2-2.5 days on a single charge.
Asking what the best ROM battery life is is like asking what the best bass for metal is hiding: ). It really depends on your phone, and how heavy of a user you are. But if you want an actual answer, I get the best battery life with Xboarder's Stock Gingerbread ROM.
I dont use my phone a lot and my TWAS is usually 0%. I dont use my phone alot, but usually when 5-6 hrs of no use or very light use it has gone down around 20-30%. Anyone have any ideas of what rom would work best for me? I am on ICS 5.0 right now and it seems they are not coming back with their 5.5 they had out. I really only care about great battery life and having some type of hotspot hack or free tethering.
Thanks.
You have to try each one and see what works best for you. Read the ROM threads. Every phone and user is different.

I have been using the latest sleeper rom and i have left it at 1000mhz no overclocking and i seem to be getting better battery life than i was with some of the others. i flash frequently and i would agree with kennyglass in that each one works differently. so try for youself.
Well, like everyone else said, its depends on what your phones handles. Everyone phones handles a rom differently, well, not that differently, but enough to make big differences.
Like the guy above me, I also use SleeperRom. Its a very stable, battery efficient rom.
here is a list of roms I would try out...
ACS_ICS_V5.5
LegendaryRom
MarcusantROM
StarskyROM1.5
I also recommend CleanGB by toadlife. Fast, clean, stable, full day on original stock battery.

I personally would towards 'which kernel should I use?' You've got to remember that although we all have epics, not every CPU is the same. What I am running it he or she is running may not be what you should be running. If you ever check out an oc/uv thread, you will see that people get different results using different settings, even though we're all on epics. You've got to try a couple different setups (roms AND kernels) to see which runs best for your device. Good luck!
via my EPICally transmogrified EI22: adrenaline injected & Supercharged
I currently use CleanGB which has been pretty great. If you're in an area with iffy service, that'll kill your phones battery pretty quick.
After installing a new rom make sure you charge it to 100%, wipe battery stats and then let it die without charging to get the most out of your battery (and having an accurate battery indicator)
In my opinion the way you configure your phone has by far the biggest effect on battery life, followed closely by the signal strength of the area you are in, with maybe a very small effect caused by the rom/kernel combination. Watch what you have syncing. Facebook and Twitter syncs can kill your battery, as can any other app that's always using data. Also, wifi uses WAY less battery than 3G or 4G. Use it when you can.
I'm on stock EI22 with mkasick's kernel and I usually get a full 16 hours with power to spare.

Basically Poit. Since no 2 people use their phone the same way it is retarded to ask for a comparison of best battery life. People need to stop being lazy and just try the ROMs out and compare for themselves based on their own use.

I agree. I have seen 3 questions over the last 2 days with these dumb questions.
but if I was to give my advice, I would strongly advise trying MarcusantROM, Battery life is pretty amazing, just be sure to flash a different kernel, as 2.0.6 is not even offered for download anymore because of bugs n such.
I would strongly advise the Shadow Kernel, paired up with MarcusantRom. You should see some pretty amazing battery life with that combo.
or try these out...
LegendaryROM
SleeperROM
Come on... "Dumb question"? "Lazy"? Get off your high horse. Certain ROMs give better battery performance than others because of certain tweaks and the OP asked for some general advice. Certain ROMs are certainly worse than others. OP wasn't asking for what would be best for him but what has worked good for others. Why is it so wrong for someone to ask for general advice about a ROM/Kernel combo. Not that hard of a question and not so ambiguous that it deserves a "dumb question" or "stop being lazy" response. If you don't want to help the OP, then simply DON'T RESPOND.
As for the question... I generally use the kernel that is included with the ROMs because normally that is what the developer has tested the most. I think Thunderhawk, Sleeper, and Legendary (in that order) are all good for battery but I haven't used all of the others.

In kind if you don't like the responses don't respond to them. I read for a month all the ROM threads before deciding on one to flash. Go to ANY ROM thread and someone there will claim they got the best battrery life there. It is different for every body and EVERY phone. ALL of the ROMs here have tweaks that work differently for everyone depending on use. Also people are sick of every other thread as "what's the best ROM". You HAVE to try them for yourself. If we are being to real for you then don't read what is written.
I was once where you are now. When I couldn't find a satisfactory answer, I made my own solution. I'll be uploading the latest version of it, version 3.3 today or tomorrow.
Battery Used: Extended Battery 2700 mah
Testing Performed: Idle Only
For those unsure, idle testing is simply when you treat your smartphone more like a phone. This included uses such as, checking the weather, responding to the occasional text, checking the time, etc. The primary goal of idle testing is to understand how long the phone can stay alive when used for texting and phone calls only. This is useful primarily for occasions such as, going on vacation, where you would like your phone to last a week or more in case of emergencies, but you'll be preoccupied and not killing your battery with Angry Birds. It's nice to know that our phone is capable older, simpler cellphones in standby time.
This indicates that my phone could stay on for as long as 10 to 14 days.
Direct arithmetic calculations indicate as much as 5.5 to 8 days on the stock 1500 mah battery.
Obviously, usage varies greatly between people and even between days, so anything other than idle testing is subjective. Testing was not performed on a stock installation, but rather, on my own daily personal fully-decked setup.
On the stock battery, I've played games for a total of more than 3 hours over a 48 hour time period before needing to recharge.
This has held true on my phone, my wife's, her mother's, and more than a thousand other user's phones. Yours may vary. Try them all. I do.
Looking forward to Random's latest!

Hey there XDA, got a question for ya.
I've had my AT&T S3 for a while now and I love the phone a lot, the only thing that is plaguing me is the battery life.
Now for a phone with dual core processors, a nice Super AMOLED screen that runs at 720, all the connections that you'd ever want, I expect it to use some battery life, but I feel like I should be doing better than I should.
When I'm browsing the internet or reddit I can watch the percentage just slowly crawl down. Within 30 min or so I've gone through 7-8% I want to say. Not 100% sure, but the numbers have been enough to make me concerned.
Currently I am running Diet ICS 08.08.12 with no major modifications other than the apps I use and Apex Launcher.
I've got my BetterBatteryStats dump and a screenshots of the battery page from System from last night. I'm attempting to use Juice Defender today (I've tried it in the past and it did alright) as well as Samgsung's battery saving mode (which seems to prevent the processor from going over 1.0 Ghz), which as of right now I'm at 36%. I feel like I can do better than that
So, thoughts? Opinions?
What kernel are you running?

I don't think Diet ICS swapped kernels, so stock as far as I'm concerned.
Alright. For stock kernel (I'm not too sure about with power saving), those numbers are fairly decent. I was able to get some better numbers on faux123's TW kernel (the 1.65ghz, not 1.85), but I can't be too sure of the exact time, as I'm currently on 1.85ghz OC, and I charge my phone nightly. You could try other kernels, and just roll back with a nandroid to this one if you do not like the difference.
