I used my iPhone 5s at work from full charge to about 28% on AT&T LTE, then headed home at 7pm and used my phone on wifi for a while and headed to bed. Bluetooth on, Wifi on, automatic updates, background refresh and auto brightness on. Did lots of web surfing, looked at a few videos and photos. Got my phone on launch date, ran the phone til it turned off, fully recharged to 100% then left it on for additional 2 hours to trickle charge and top it off. Did that twice so far. This will be the third time. Then I'll charge it whenever for the most part. I get the new iPhone every year.
Did u restore from backup or setup as a new iPhone ?
