Hi, I just got a brand new iphone 5 and the battery life is really struggling for some reason. I took it out of the box and synced it an charged it to full. Last night I went to sleep with 100% and woke up 7 hours later with only 20% with no use. I had all my apps closed. Blue tooth was off too. I have had to charge it basically all day today too. Any help would be much appreciated before I try to deal with apple or getting a new phone.
