so ive noticed over the past month or so that my 2g iPhone's battery life has been declining, but today was ridiculous, and i want to see if this is normal wear and tear, or i should take it to the genius bar. i charge it to 100% every night. It gets about 6.5 hours of charge time a night. Today I took it off the charger at 7:30 am Throughout the day I listened to about 45 minutes of music, 45 minutes of app game use, and about 10 minutes of internet over wifi. I've only sent and received about 7 texts today, and have received 2 calls that lasted less than a minute. By 3:30 pm the phone was down to 20% battery. Wifi is always off unless being used, bluetooth is always off, brightness is set to less than 20%. Push is off. should I take it to the apple store? Thanks!
