Hi, My Iphone 4s seems to use a lot of battery for example I turned off WiFi, Location services etc overnight but when I checked this morning, it has used more than 50%+ of the battery. I am worrying about the battery dying during the night and missing the alarm in the morning etc. My old nokia phone hardly used any battery when I wasn't using it. I normally keep my Iphone plugged into my USB port on my PC during the day but if I don't, I end up charging it 2 or 3 times a day. Is the above normal behaviour for a 4s? I know the battery life is rubbish on the 4s but I didn't think it was so rubbish.
