I am now getting less than 8 hours with about 10 min talk and 30-45 screen on. This is with GPS off, 4G off, wifi on. Used to make it thru work and get charger notification around 10pm. Now by 3pm, need to charge, I do nothing after that not even screen on and phone dead on less than 1 hour. I absolutely hated this phone battery before and find it unusable now.
