Battery Life
Equipped with a 2300 mAh non-removable Li-Po battery, the HTC One had a mixed battery performance. It offered a standby time of up to 500 hours on 2G, and up to 480 hours on 3G, with a talk time of up to 27 hours on 2G and 18 hours on 3G. However, its real-world battery endurance was somewhat limited by more intense usage, resulting in a disappointingly low endurance rating of 48 hours.
