I just got a new iPhone 5 on cyber Monday and i wondering what is normal standby time. I really don't use my iPhone that much, mostly to look at the time. I've own the phone for 9 days I've only sent 28 text messages total and made 2 calls that lasted less than one minute within those 9 days. I took the phone off the charger at 11AM and now its 2:16PM and the phone has 81% left, I only sent two text messages and all the other time its been in standby mode. I've searched around and find people who will charge there iPhone 5 at night when its done charging they take it off the charger and leave it all night and wake up with like 98% left. If i do the same my iPhone will be dead when i wake up. I don't even use the phone and the battery dies, every setting is off but yet the phone dies when not in use.
