Just curious if anyone has this same issue that I have. Today I listened to Pandora radio for about 2 hours while having the screen turned off. I thought this would drain my battery to maybe 50% or so? Not really sure my numbers can be trusted anymore. But after listening for 2 hours my battery life was still like 90% full. Then about an hour later after having the phone idle in my pocket, I updated an app through the market and it said my battery was 5% and I needed to charge it. So thinking I would need my phone for something important later I turned it off. Then 3 hours later my battery was back up to 90%. When I got home and plugged it in it said "Charging 80%" so im completely confused if I did something wrong or my battery is defective. Any thoughts would be appreciated.
