I had read this post http://androidforums.com/support-tr...0-how-battery-life-droid-x-2.html#post1261548 and figured I'd download Spare Parts and see how my phone looked. It showed my phone had been running (not sleeping) for almost all 12 hours since last time unplugged. So, I methodically plugged away to try to figure out which program I was running that caused the phone not to go into sleep mode and it looks like it's Maps. I rebooted my phone, plugged in (to reset the since last unplugged timer), turned the phone off for a few minutes a checked the running time and it was normal. I started maps, plugged in, turned it off for a few minutes, then checked the running time and it was pegged at 100%. I did the process a 2nd time and got the exact same results. In addition, I think killed Maps using System Panel and that did not fix the issue. The phone still wasn't sleeping. I wonder if maybe Maps is calling up some other process and it's the other process that's causing the phone not to go to sleep. Anyone have any ideas? Can anyone else test this as well to confirm or refute? Perhaps this is why some people are getting way better battery life than others? I'm interested to see how my battery does tomorrow. I'm not expecting a huge jump as I doubt I've run maps ever day, but I guess I'll see what happens. EDIT: Upon further investigation, it looks likes it might be once I run an app that activates the GPS, the phone no longer sleeps. I just rebooted and ran Poynt and the phone didn't sleep. I then disabled the GPS and the phone went to sleep normally. I then reenabled the GPS and the phone still slept normally. I then started Poynt again and the phone didn't sleep. I disabled the GPS and the phone slept. I reenabled the GPS and the phone slept. I'd be very surprised if others didn't have the exact same issue.
