Hello all, I have had my first iPhone since Thursday of last week. I am finding the battery performance is not good. For an example, yesterday afternoon my battery level was at 100%. This morning it's at 32%. My activity is low, I sent one text, sent 2 iMessages, browsed 1 web site (amazon.co.uk) very briefly. Location services are off, auto lock set to one minute, auto brightness activated. Wi-Fi was off overnight. I have not made or taken any phone calls. I do use the phone as an alarm clock, and as a reminder to take medications 3 times a day. Is this poor battery performance normal?
