[Q] Battery draining at 1% per 30 seconds!?

---

Hello. I am having a problem with my Evo 4G. I recently replaced my Evo 4G, and I changed ROMs as well. My battery seems to be draining at 1% per 30 seconds. I can't make an hour on a 3500MAh battery. It doesn't seem to matter what ROM I try to run.

So my question is this: Is my battery the problem or is there a problem with the Radio, PRI, or some other nonsense that is running crazy and draining the battery?

Thanks!

have u tried a custom kernel? what rom are you on right now?

check battery usage, menu-settings-about phone-battery. Also download Spare Parts, go to battery history and see if any apps are hogging the battery.

The display is using 82% of the battery. This wasn't the case when I was running Android 2.2. Now that I am on 2.3.3 it seems like the display is hogging the battery. I would like to use a custom kernel that is best for battery life. Can anyone tell me which to use? I am using MikG's ROM v2.15, I think. My info is Android 2.3.3, HTC Sense 2.1, Software 4.24.651.1, PRI 1.77_003, PRL 01115 and Baseband 2.15.00.09.01. I have the display set to turn off after 15 seconds, so I have no idea why the display could be using so much battery life when it sits off in my holster most of the time. My job is being oncall 24/7, so battery life is a must. Can anyone help me solve this please? Thanks!

Also could be an issue with the battery itself. Can you try a different battery? Is the extended battery one of the Hong Kong variety? Have you tried wiping battery stats?

Sorry dude so far there are no custom kernel for any sense 3.0 roms yet cuz htc hasnt released the source code for their kernels yet but when you flash a sense 3.0 rom it has bad battery life for a few days but later the rom gets very good battery life...

That is true, took my friend's phone 2 1/2 days for the battery to settle in.

It says Sense 2.1 though. I don't even know what this Sense nonsense (haha) is. My previous ROMs didn't use it. Maybe I should switch to a non-Sense (haha again) ROM? Or are there Sense 2.1 kernels available?

Actually I did change the battery. I used two different 1500MAh batteries and one 3500MAh battery. I heard it was the PRI and it needed to be switched to version 1.77? I have that, but it still seems to suck. I did wipe the battery stats, so maybe wiping the stats caused the issue? I was told it would make the battery work better. So confused...
