Battery Life
One of the standout features of the Gionee M2 is its battery performance. The phone is equipped with a sizable 4200 mAh removable Li-Ion battery, which was quite generous for its era. This capacity translates to an impressive standby time of up to 555 hours and talk time of up to 31 hours and 30 minutes on 2G networks, and about 24 hours on 3G networks. Such endurance would easily handle extensive usage without frequent recharging.
