I replaced my phone a few days ago and am extremely happy with it. I did just get done with an "unofficial" test of the battery. I turned airplane mode on, auto lock off, full brightness and auto bright off. I let it sit for 1 hour. I was told that if the phone went 1 hour and did not go below 90%, it is good to go. I know this is not anything offical and what not. Just looking for opinions. That sound right to you guys? I am going to charge it up fully tonight and leave it go overnight. I woke up to my phone being 80% from last night and I can't remember where I started from. That's the only reason I ask.
