Battery Life
Powered by a removable Li-Ion 1800 mAh battery, the Lumia 822 offers satisfactory longevity, with up to 11 hours and 40 minutes of talk time on 3G and an impressive music playback time of up to 62.1 hours. The user-replaceable battery is a practical feature that allows the swapping of units to extend device life, a convenience increasingly rare in modern smartphones.
