I got my new iPhone 4s the other day, and have charged/discharged it a couple of times and still the battery is VERY poor imo. Went to bed at 100%, and put it in airplane mode with an alarm. 6 hours later and it's dropped to 98%. Then upon switching off airplane mode, I checked email, facebook and whatsapp messages. Battery dropped to 83%. After a 13 minute call, it has dropped 77%. Current stats: 76% Usage: 1 hour 41 mins Standby: 10 hours 20 mins (6 hours on airplane mode) Should I make an appointment at the genius bar? or are these stats satisfactory enough that I should wait for an update?
