I just purchased my new Razr Maxx HD.. I have it on unlimited data for 4G.. I initially put it on the charger for 2 or 3 hours... Powered it on, activated it.. The battery reading 100%... I have audible with quite a few audio books so I decided to put 4g through it's paces.. On the first day I downloaded 8 Gigs data.. Mainly audible books... I noticed the phone was feeling a bit hot... My concern is will that cause a problem with the battery? I'm able to run the battery almost all day but seems like not quite like other's I've seen.. My numbers are.. Screen 75%, Phone idle 7%, Android OS 4%....... Screen time 4 hours 58 minutes... Remaining charge 15%... 13 hours 58 minutes on battery... These numbers seem a bit low to me compared to others I've seen .. What do you think?
