Hi everyone. I bought my iphone 5 on Christmas day. Yesterday was the third time this has happened where I have been out and about and had plenty of battery left, and then all of a sudden it switches off, and when I try switch it back on, it acts as if it has no battery with the red battery picture showing. Yet when I get home and connect it to the charger it turns on and has the same amount of battery it had previously, as if nothing had happened. Anyone got any ideas as to whats going on? I'm in the UK, and tomorrow will be the 90th day I have had it, I don't have Apple care or insurance, what could I do? Thanks guys.
