Battery draining on cm10 - Epic 4G Q&A, Help & Troubleshooting

Is it normal for the battery to be drained so fast on cm10? This crazy, I think I'm going back gb until cm10 is offical.

There are only about 1000 posts on finding battery drains and CM10 battery saving tips. Rule #1: Search before posting.
You also give absolutely no information. You might as well say "I am bleeding, should I go to the hospital?"

Need combinations!

Hey all, I need assistance. I'm currently using cm9 beta and the battery life is horrid. I'm also using the Nyan kernel.
Anyone know of a rom/kernel combo that has long battery life and decent performance? Touchwiz or not?

It comes with Shadow so you should be all set. Or you could try Samurai if you like. Lots of people have great success with both.

Most have issues with wakelocks when they try to use their phone the way they want on any ICS ROM. Enjoy everything working and no greens in the super battery sipping The People's ROM. 4 Hours display time with 30% battery left on stock battery....hell yeah! One user reported 50 hours with over 30% left. If your phone prefers Samurai kernels you can always switch from Shadowkernel.

Because I tried all the ICS combos and you can't beat TW for battery life...period! Try The People's ROM for 2 days. I bet you will admit you get close to 50% more battery life. I have 4 emails syncing, LED notifications on, sounds on..all that I want without getting wakelocks up the wazoo.

A process that prevents the phone from entering deep sleep and causing faster battery drain.
You can check for these by using Better Battery Stats.

The wife is on stock EL30. I'm running ICS with Nyon. My battery life absolutely rapes hers, so I'm gonna rule out the TW peoples ROM. On side note, the FB19 modem seems to work nicely with the new PRL update.

Wake-Up Lag ICS

I'm sorry for asking many questions lately but I am kinda of a newb with this phone, and was wondering if there is a way to fix the 2-3 second wake lag that continues to piss me off?
Sent from my SPH-D700 using XDA
Try raising your minimum frequency to 200mhz and see if that helps. Back in the day 100mhz was causing wake issues so I wonder if that is still an issue for some CPUs. Battery life loss will be negligible.

Me either. Did you restore data from a previous ROM? On my first install of CM9 I broke the rules and restored some system app data. That caused me a fair amount of problems.

Is this battery life normal?

Since my last post went completely off topic and hopefully will be deleted soon I am going to try again. I flashed CM7 last night and ran a battery calibration and I only had a 4hr 19min battery life with moderate use I updated my radios but my baseband still says 2.15.00.05.02 Instead of 2.15.00.08.02 did I do something wrong in the flash? I put it in the root of my SD card and flashed it just as I would with any zip. Here is the screenshots from my test.

If you want the current radios see this.
Has the recovery install as wall as hboot install.
Edit: did you have this with your previous rom?
Perhaps a new battery will help if yours is old?
Yea that is definitley not normal batt life. I'm not saying mine is great, but usually i can go a day on my batt with light to moderate usage. Usually just checking fb, xda, mikmik, and a few minutes of internet surfing
Yeah battery life was right about the same I never tested it. It was sprint lovers rom. I have a new battery coming in as soon as tomorrow so I'll test it again once I get it. Is there any suggestions for things I might try?

Well this is from my galaxy s3, But when I had the evo I had decent battery life. Have you tried flashing a rom?

You could also calibrate the battery again.

I just did before I let it drain but I'll try again. But I am having an issue updating my radios. I downloaded the newest one from the link above and I've tried installing zip from SD and apply update from SD and neither one of them worked it says installation complete but my base band doesn't change and the steps posted in the link don't show up when I'm doing the update what am I missing? I am using revolutionary instead of amonra

There is no need to kill anybody son... Just get "Juice Defender" like he did and you'll go a day or 2 the same way... No real mystery to it...
Ok I am assuming no disrespect was intended but do not refer to me as son being 27yrs old and a veteran I can't stand that. And secondly thank you much for the juice defender idea I'll go dl right now and give it a shot

Try them all is all you can do each one is going to be different for everyone.
It is lack of signal that kills the battery, not the modem. So if you find
A modem that gives you better signal for you then that is the best you are going to get.

The nexus modem helped me out a lottttt on cm7. I used to barely ever get a bar in my basement so my battery always died cuz of searching but I'm very very impressed now.

Probably. I haven't ran cm10 in awhile but if the updates re-write system files then most likely that mod will be erased each time.
