Nokia Lumia 900 AT&T Battery Life

Battery Life

The device houses a non-removable 1830 mAh Li-Ion battery which provided up to 7 hours of talk time or up to 300 hours on standby, translating to a battery endurance rating of 29 hours. Music lovers enjoyed the perk of up to 60 hours of continuous playback. While satisfactory, the battery life required frequent charging with moderate use, a fairly common limitation for smartphones of that era.
