LG Optimus LTE SU640 Mobility and Battery Life

Mobility and Battery Life

A removable Li-Ion 1830 mAh battery powers the LG Optimus LTE SU640, providing up to 400 hours of standby time and up to 7 hours of talk time. The removable battery feature is practical for users who prefer to carry a spare or replace their battery as it ages, a convenience often missing from modern smartphones.
