battery draining very quickly
since my last upgrade to 1.7.64 my battery is not even lasting for an hours run?? can anyone help please? i was told to do a factory reset but this has not fixed the problem at all,i do not use anything on the phone to drain power and most things are switched off including the music,so it is just the running its being used for,it use to last for around 5 hours but not even 1 hour now,has really put me off using tom tom,surely if its an upgrade problem it should be sorted straight away by tom tom??
