Sorry for the newbie question, I'm new to macrumors and the iphone. While reading a book in either the Kindle app or iBooks, I notice a 1% battery drop every 10 minutes or so, my question is, is this normal? My screen settings are around 30-40%; wifi, 3g, bluetooth, location services are all off, push and fetch are set to manual. I would catagorize myself as a light to moderate user; minimal web browsing, usually using wifi, minimal phone calls, maybe 10 minutes per day, minimal gaming, nothing 3D intensive, 20-30 minutes of reading, sometimes some ipod use, 15 minutes or so. I've been concerned about my battery and was told by applecare that the battery drain I'm seeing while reading is normal. I've also had a diagnostic run on my battery by the apple geniuses and was told my battery was operating normally. So what do you all think, am I just being paranoid? Thanks for any help or suggestions!
