6 Plus. Moderate use = apx. 70% battery life when I go to bed. Moderate to above average use = apx. 50-59% when I go to bed.
My hours of use off my charger are generally from 6:30am to about 11pm-Midnight.
I've had maybe one or two days in the last two or three weeks I've had the phone that got me down to below 20%. I was using the phone heavily then.
