I don't like PB3. For my 5S, it's the worst. Performance wise, I haven't noticed much difference between the three. But this time the barber is draining at an alarming rate!
I normally unplug my iPhone at around 7.00, and not plug it back in until 23.00 or midnight, and still have between 20-30% left. Immediately after installing PB3, I noticed battery drain and warmer device. Yesterday, I went from 100% to 20% in
4-5 hours, just listening to music, and sporadically checking on Facebook). I just turned into a wall hugger!
