On my phone when I have 3g or 4g on I get HORRIBLE battery life. Like 4hrs at max. I can practically watch the percentage go down (like 1% a minute)and the phone gets super hot. I have bumpcharged / calibrated like 10 times now.

On wifi its fine. Amazing even. I could go days with it. And its not like I have an app thats running. Android says its all the cell usage.

Im using CM7 rc1.5.2 and MR2.5, As I was typing this post I flashed MR2 to see if it helps.

Anyone have any other ideas? Thanks

I just found the chingy one from his RUU Is that newer then mr2.5?

What kernel are you running? Some kernels have issues on some phones. For example, if you run Imo's kernel that unlocks 184MHz, some phones react horribly negatively to this and chug your power and overheats. Give us more info about what you're running and what you've tried. Also, try some other kernels.

 

[Mitchell4500]

Im using tiamcat. Sorry. Iv tried Imo kernels too. Not the one your talking about though.

Thanks for the reply.

What clock speeds (min and max) do you have it set to?

 

[Mitchell4500]

Min: 268mhz
Max: 1036mhz

Governor: Conservative.

In my opinion that's just how it is. My Thunderbolt is the same as yours (excellent battery on WiFi, even better when not connected to anything).

I'm running OMFGB with Imos kernel and here are rough estimates of my battery life with what I consider medium usage:

4G: 4hrs
3G: 6hrs
WiFi: 10hrs
No data: 15+hrs

When i look at the 3g status icon I see just about every 2 seconds it lights up real fast. It seems like maybe Some app might be using lots of data. But I can figure out what because the Battery Usage tool in spareparts never says anything is using it.

Download system panel or better battery stats. Let it run in the background and then check it and it will let you know what's pulling battery in the background.

I use chingys radio and imoseyons kernel and have no problem getting 20 hours on straight 4g with moderate use including pandora. Two apps that have doubled my battery life are 2x battery and brightness level (25% indoors and 75% outdoors).

I'll go get isomons kernel and give it a try

Here is something I did. I just turned the phone off and let it charge to 100%. Then I unplugged it counted to 10 and plugged it back in. To my surprise it started charging again. Then I just kept doing that until the light was green when I plugged it in. Turned on the phone let it charge all the way up to 100% used a battery cal app and BAM! Great battery life... Hope this works for you.

 

[Mitchell4500]

Yeah Iv done that about 10 times lol I think it has something to do with the radio or kernel. Right now Chingy's leaked radio and Isomons kernel seems pretty good.

Turn off update intervals on all you data using apps like Facebook and twitter you will still receive push notifications and you can refresh them manually..some refresh on launch anyways.

that's what 2x battery does for you

Id use that app but I use Google Voice for texting and Im not sure how that would work.

Same here, that's why I've stayed away from that or Juice Defender.

It'd be really easy to test

Check out juice defender you can set which apps you want to always get data, as well as set autosync on a schedule or have it only sync your google apps and wait to check facebook and twitter every couple hours. I loved the location enable/disable for wifi when I was on sense, but it doesn't work that well on cm7 because of the network location issue.

My phone acts the same way on AOSP roms, horrible battery life. I am a very heavy user & it lasted 4 hours on the last cm7 version I tried. I'm on Gingeritis 1.2.x & I get 10-12 hours out of it now. No juice or battery Apps running, no change in my use & I am in a 4g area.
