Charging iPhone 6s
I charge my iPhone 6s Plus over night.
3-4 hours before I go to bed, I have my battery at 15-20%, currently 24%. Is it okay to charge a bit, for example from 20% to 35% and then unplug and put it back when I go to sleep? How does it affect my battery life?
iPhone 6s Plus, iOS 9.0.2
