Hi CBerries, do you know the reason why in the same condition of usage the phone get warm and drain a lot of battery? Some days I arrive to the end of the day with the 50% of the batt, other day with similar usage, the phone reach 40% in 5 hours. I alaways close all apps, switch off wi-fi, I use a very low screen light. This thing get me nervous. Any suggestion?
I really wouldn't worry about it, my phone was very hot after doing the 342 update the other night, and it gets warm occasionally. As Wulf said, you may be struggling to find/keep a signal.
