hello:
my evo 4g battery lasts less than one day.
I googled but didn't find any good suggestions.
if I flash a custom rom to remove all bloatware, does it help?
thanks a lot.
I would also like to know this.

This should be in the Q&A, I Belive but to answer this question, a lot of things affect battery, first a old battery of course won't last you so long. Second are you running a custom Rom? And overclocking it with like CPU tuner or simmliar.
Are you running your brightness high,is your 4g on all the time, are you using music or social media a lot, playing games and so on.
That being said, moat customs roms can improve battery life to a degree, aswell as the kernel you use and what setting you are running it at, for instance I m running my custom Rom with underworld v8 no halvs sbc kernel
And my governer Set with ondemand at 769 max or something like that, I don't run 4g when I have WiFi, and my screen brightness is set low unless I need it brighter I will change it, I also have a lot of tweeks in my build prop, which a lot of other devs do aswell to help with battery life.
There is a nice section in these forums that explain governers you should read it, you will learn a lot.

I get about 2 days with normal use on my setup.
Hope this helps.
Also its always good to wipe battery stats when flashing new roms, also discharge battery fully and then charge it fully.

Custom roms usually have better battery life. On average I get the best life out of the sense 3.5 roms with the aggressive lionfish kernel but the kernel does not support ext4. Sense 3.5 also needs sd-ext partition to run and when changing kernels you must manually mount the data partition before you flash the kernel.

The stock battery doesn't last very long, I'd suggest getting an extended life battery if you plan on keeping your EVO for a while.
I use my evo for music now,I thought I lost it for 2 weeks, this is airplane mode ,running cm9
Underclock, dim brightness, install a lean ROM and take off services you don't need I.g. 4G or 3g.
Other than that. Extended batteries are the way to go.

After realizing that I made a mistake by ditching my EVO for the Epic; I returned to the EVO and installed CM6. What a difference! Everything is great so far except for battery life (even using profiles on setCPU) so I was wondering what kernel would provide speed, reliability and battery savings. I'm currently running CM6 kernel and I'm getting around 1250 on quadrant (around the same results of the nexus one with froyo) so I'm happy with the speed so far but I would love some more battery life (I'm getting less than 8 hours with moderate use).
Thanks
What I learn is try a kernel for a day or two. Try another.. you will find one. Not saying do this but this is what I'm doing. Just like finding a rom.. always come back to cm6

Geez, my bad. For some reason I thought I was in the general section.
Can a mod move this thread to the general section? Thanks
Before this gets moved.. all hardware is different. On paper its the same, but what we have learned is that phones respond differently to the software thrown at them. As others suggested, try them out. Snap as well as Kings are excellent kernels. Just find there threads and I can't stress enough to read the op. Most of the questions you have can be found there, as it can be a little cumbersome with all the different versions for some. But yeah, make sure to give it a run for a few days before you decide its not working for you. Your phone needs to get used to it, so basing it off a charge after a few cycles is always a good idea.

Run Snap v7.5 for an increase in speed and battery life.
King's Kernel all the way, and I've tried all the damn Snap kernels.
Mostly, you should be managing your wifi/3g/screen off cpu settings.

I've been using King's #1 kernel after trying (and having issues with) a myriad of Snap kernels. I really like King's and am waiting for #2.
Running starburst rom v1.9.8r and its awesome! Thanks phantom for all your work! And thanks to everyone else whose software im using!
Battery life on a few previous roms were a bit low, maby i didnt give my phone long enough to get used to them, but my current set up gives me some of the best battery life I've personally had since before root and starburst v1.8 which were each beast.

Way past my daily charge time and still going strong. connected to wifi a lot,used google navigation for about 90mins of driving, been web browsing a lot/texting/little music/some camera. Nothing spectacular like gaming and videos but my main worry was to make sure i had enough battery at the end of the day to gps back home lol. Dont worry about the few minutes of charging at the end, was showing off netflix through hdmi so kinda needed to have charger plugged in so give or take 2% if you're- why so serious?
Set up:
Sb rom v1.9.8r
LoStKernelExp 1.0.0.8
SetCpu to underclock/undervolt
Viper's LoS Checker v2.1 - default set to check every 2 minutes
ICS green dialer (Idk how that would do anything)
First fully charged phone till blue light,unplugged and turned off,plugged in and let fully charged a few times. Booted straight to recovery and wiped battery data. And yes rebooted and was at 99% but hey.
Also if anyone is worried about performance from underclocking from 1200 to 800, dont be, theres hardly a difference in performance. I play Defender -droidhen- alllll the time and there was absutely 0 performance issues even when using spells and flashy stuff on stage 92. The gps works perfect,no lag between voice and location/distance from next turn (and was on 3g). The single thing i notice is that when on flash heavy web pages, there tends to be a bit more checkerboarding while scrolling up and down, but the pages themselves load up as fast as always.
For the extra bettery life, i think its worth the microscopic performance sacrafice? Anyway I hope this helped anyone wondering about battery life and how I extend my own!
Would love some feedback if anyone is getting better results!
Looks good...still testing tho.
Thanks!
I'm really curious to know what the battery life on CM10 is since I used to have FF18 and I have to say that it wasn't as great as I expected it. Right now I downgraded to EL29, mainly bc of battery consumption but I want to know other people's experience with CM10.
The cm 10 battery life will vary..for Me Jb battery life is fine..with a little effort it is very possible to get good battery life..was it as good as ICS.?.honestly no..but ICS has source for our device and source for in on our device hasn't came

I barely even use it AT ALL, and battery is at 32% after less than 10hrs. Also, playing Bad Piggies for 30mins, and it'll go from a full charge to 12%.
ICS wasn't any better for me either, but I think JB is a tad worse...
im running nightlies from phantomphreak and im getting 13-15 hrs average. thats with moderate usage. best thing you can do is set it to 800mhz max and conservative. everything still perfectly smooth for me
heres my battery life with the latest nightly from phantom freak. cpu set at 800mhz max with pegasusq governor
absolutely terrible lol i gotta charge it like 2-3 times a day

Since there is no info in your post, no one can help.
Been having battery issues ever since I flashed a 4.2.2 ROM.. I think its the modem. Being on like over drive, draining my batt.
Or is it 4.2.2? I tried all the 4.2.2 Roms that there is for our phone. And its seems to drain at the same rate every time. I don't know of its just me or can my radio be the cause of it. Or android 4.2.2??

Battery Drain......?! Try Battery Not Holding Any Charge!
I've kind of got a similar problem. Can't quite figure out what is causing it though. Everything was fine until I updated to tha latest nightly last night. It slowly took a nose dive after that. It actually died all the way out on me while sitting plugged in. Now, as I stated in the title, it won't hold any sort of a charge whatsoever. Every once in a while I can get it to boot up but almost instantly it shuts right back own. Can't seem to boot into recovery either, but have gotten it into Download Mode pretty easily. That's where it'll remain on for the longest duration, but still not long enough to be able to reflash anything to it. The battery state check said the battery health was good all the way until it completely died on me the first time. There has been no moisture or other damage done to it in an kind of way either. Any ideas as to what exactly the issue at hand may be?
Sounds like it might be your battery...know anyone with an s3 that you can use there battery for a bit to see if it charges...if so then its your battery if not might be the ROM or phone.

I'm running the most recent PACman ROM, which is 4.2.2 and what I do is set my governor to interactive and my I/O Scheduler to SIO. Running stock kernel at the lowest min and highest max, I can get almost a day and a half out of a charge. My trick is to toggle things when I'm not using them. I mean all the time. Screen brightness never above halfway, no haptic feedback, no live wallpapers, and I'm always clearing my recent apps. I don't know if this'll help you any but that's my battery saving procedure.

I really don't know anyone with an s3. Seems Apple has everyone around here convinced they're better. HA HA! That's a great laugh! Seriously though, there is a used cell phone shop I'll go talk to though. As for my kernel settings go I run interactive, on demand, 648 & 2100, under volt everything 100, and either raise or lower all other settings within one point from the least or maximum it could be. Been running that since I got the phone in September without any problems battery wise whatsoever. I'll start with checking the battery though and see where that journey leads....... Thanks for the thoughts and suggestions.
Please my phone litterally died in 3 hours from full charge with 1hour screen on time
Running FINAL SOurcery and Faux 29u kernel underclocked at 1000 mhz with intelli demand
First things first, don't ask "best" type questions on xda. Everybody has different experiences.:good:
That being said, I am personally always running the latest AOSPA (Paranoid Android) and latest AK kernel. Great ROM, and absolutely perfect kernel. I usually get around 3 hours on screen time with that combo.
Of course, you have to remember that there are many many factors that impact battery life. For example, if you have data turned on (either 3g or 4g), gps on, or brightness high, your battery will suffer. Search the forums for various ways to improve battery life.
I always have the best results running stock for battery life.

^^^This. If you are having that crappy of battery life, its most likely the battery itself. No ROM or kernel is going to help you.
Mine too and i have baked +Franco.

This is heavy use (3G only, no WiFi) also I'm with wind so having a crappy network signal kills it even more, yours will most likely look better.
