How to extend battery life.

i think sense itself is a big battery killer. if your all about battery life then disabling sense would save alot

Very nice. It's time to start tweeking some settings.

+1 for this

we, Admins, got that message. I don't understand why Jenn K. Lee demanded to take it down and just post the link... well, one reason is to get more traffic in their site (which I may add that has some cool info).

So if I tell someone "Turn off haptic feedback", am I breaking any copyright laws?
Maybe I have to copyright the name Jenn and demand for him/her to change it! 

Anyway, that was my rant. back to reading info about the EVO

I just want to clarify so to not create any hard feelings in here. The message I received, indeed, did not "demand" I remove it. It was a friendly request that I edit the post and leave the link. I did so and got a kind reply back thanking me for the prompt action. No biggie. I understand G&E protecting his intelectual property.
It's all good. Hopefully we can all live with that and get along.
Well, hopefully this is the last post about this matter.
Everythings happiness in evoland.

Hey guys/gals! This is my first post and wanted to thank everyone for useful tips/tricks about the EVO 4G. It's my first smartphone, and I love it. My wife and I both got this phone Friday so last night I did a battery test to compare our up/awake times.

MY phone has Advanced Task Killer installed while her does not. Before we put our phones down for the night, I turned them off and back on to reset the UP time. I ran ATK on my phone to kill some background apps. On both phones I used the built in manage services to kill any unnecessary things running (i.e. media playback).

Note: I put mine down before she did so my UP is longer.

ME:
Up: 10:02 (hrs)
Awake: 00:28
Ratio: 21.5 - which to me is pretty good. It was idle sleeping for most of the time

Wife:
Up: 8:23
Awake: 00:20
Ratio: 25.2 - Better than mine.

Battery usage:
Me:
Wifi - 34%
Standby - 33%
Idle - 33%

Wife:
Wifi - 32%
Standby - 33%
Idle - 33%
Android 2%

Both of our phones hardly took a dent in battery drain over night (they were not plugged in obviously). I would note that our syncing of different services could be different b/c I don't know how often she has her set up. Mine are set up to be every 4 hrs.  I leave Wifi on per the 20 tips to save battery link by G&E. Tonight I'll do a similar test with Wifi off to see if anything changes. I tried to keep the post short. Looks like I might not bother with ATK as most of the apps it kills, just start themselves again anyways (Amazon mp3!) Wish I could just remove that app completely!

On moderate use, I think I'll be able to get through the day without charging which is fine with me. I'll have a charger in the car and at work just in case. Might buy an extra battery and/or solar charger for times we'll be unplugged for extended periods of time.

From home screen click menu-settings-about phone-battery-battery use.  You will see the info there.

So I did another battery usage test last night. Same syncs times for services except this time I had ATK killing tasks every 4 hours. WiFi turned off.

Up: 7:40
Down: 0:28
Ratio: 16.4

Battery Usage:
Cell Standby - 49%
Idle - 49%
Android - 2%

Minimal battery drain but the up/down time ratio fell. Not sure if it's a b/c ATK was turned on to work every 4 hours or Wifi turned off. Guess another test will be done tonight.
