Mm...am using standard Apple charger. No fast charger. Not sure if that is a factor. However, my 8 month usage is light to moderate. For videos, I normally just use Youtube. No Netflix. The small screen is just not apt for long video watching. I usually recharge once I reach 20 to 50% and always remove the phone from the charger once I reach 95 to 100%. I do use the car charger when I am driving and when using Waze (huge battery hog).
