First off-I *LOVE* my EVO...now here's my problem. I've had erratic success with my battery... I'm running STOCK...I haven't, and really don't want to root...personal preference. Anyway... I've gone through all the normal "stuff"...GPS as a norm is off, as is Wi-Fi (I work 10+ hours a day and don't have a use to run it). All auto-updates are off--I manually update email/FB/Twitter/etc if/when I want to. SO...in the last week or so I've grown overly frustrated with the battery only lasting 10-12 hours without charging. I did a battery pull--still no change. Made the decision to do a hard reset. I reinstalled a fraction of the apps I had before the reset...seemed to help a bit...*BUT* after a day or so I noticed my awake time at 100%....I went through a few things-decided to do another hard reset...did this Tuesday night. Things seemed fine (this was yesterday). Yesterday around lunch time, I noticed my awake time back at 100%. Spare Parts didn't indicate anything big under Partial Wake. I went through everything I could think of--and THOUGHT I isolated it to the Facebook app (even though Spare Parts didn't show it)-so...I uninstalled the chat/Facebook update...logged off the old Facebook app, and things seemed fine....awake time was normal-only "on" when I actually was using the phone--great. Fast forward to this morning/last night...I charged the phone overnight--and I'm now back to 100% awake time! Again-Spare Parts doesn't show anything under Partial Wake... I'm so frustrated! I'd love some feedback, suggestions, ANYTHING that will help me get regular, consistent, battery usage for GOOD. I hate to even think about doing another hard reset, but I'm willing to listen to anyone. Thanks in advance.
