We have two Galaxy S4's...after last weeks software upgrade the battery life is horrible. We used to go all day without charging..now we have to charge at least 2-3 times a day. The phone will discharge overnight if not at 100%. There isnt any phone damage, we have reset the bettery..it was the upgrade...i see from these forums everyone is having the same problem...theres need to be a fix soon? Anybody?? Verizon??
