How long does your iPhone batery last? Mine doesn't last 24 hours: - a few phone calls a day - a dozaine emails a day - web surfing for about 45 min After all that I have no more baterry. I shut off all notifications, Bluetooth, fetch and more options. In regards to 3rd party apps I have ebuddy and facebook. Why is my batery not lasting more than one day? How long does yours last?
