hi im looking at moving to htc and looking to get a htc one m9. currently have a xperia z2 and although i love the phone im getting sick of dropping it and braking the glass so looking to move to a metal phone this time. from the current reviews it looks like the battery is not brilliant right now but could thhat be improved with software updates or am i going to be stuck with how it is now im a fairly heavy user and use my phone a work for internet facebook etc a lot i get around 7 hours sot which does me fine. just hoping that a software update can bring the battery life we should be seeing ?
