Epic 4g with EF02 Android System taking 90% of battery, why?

[mwhiting]

After upgrading to EF02 my battery is draining within hours (2-3).
Turned off Wi-fi with a full charge at night with app killing running by morning the phone was off.

My android system is takine 90%

Compared to my wifes android, samsung also and she is running 5%
My tablet Galaxy tab is 8%

I would assume the display should be the highest.

Is there a way to track what is eating the battery?

Obviously something didn't go right when you flashed the ROM or something you have installed since flashing EF02.

This is not normal behavior at all. You have a few options...

1. Grab a full charge then boot into CWM and Advanced>Wipe Battery Stats

2. If above doesn't improve things after a charge cycle then consider reflashing EF02

3. The kernel that is being used in EF02 still has some debugging code running on it for Sammy/Sprints testing purposes so your not going to see the best of battery life yet. At the same time your reports are abnormal behavior.

I will try that.

I did not believe it was normal, thats why I posted on here.
I wanted to see others experiences with ef02.

Overall I like it. Need to get past the battery issue.

This morning after an hour disconnected and about 10 minutes of web browsing I was at 87%. Is that normal?

I did do the battery stats wipe and I did receive some better battery life but not much.
I also reinstalled EF02 and the % of the Android System has gone down but only to about 50%.

I get about 6-7 hours of standby usage from the phone.

I have the same, ever since I flashed EF02, this phone has been horrible. I charge three times a day...at this point I have become used to it...but i really wish I knew what was draining it or if there was an app that can help me with that.

My android system usage is like at 85%...i tried going back to stock froyo, it didnt help...i try calibrating battery didnt help...i'm not on the latest GB rom, its still the same.

somehow when installing EF02, something really in the core of the phone got changed which is not getting ovewritten when flashing new builds/roms.

Have you guys had any luck yet with this issue?

I had the same problem with EF02. Battery life is much better with EG22 or EH06. You could try one of those leaks or hang on a bit for the next leak which should be out tonight or tomorrow.
