Battery Life
The ZTE Anthem 4G is powered by a removable 1780 mAh Li-Ion battery. With a standby time of up to 244 hours and a talk time of up to 4 hours, the battery life could have required frequent charges with moderate to heavy use, a common scenario for smartphones of its era. The easily removable battery was a practical feature, offering opportunities for users to replace the battery once its longevity started to fade.
