Microsoft Lumia 640 XL LTE Dual SIM Battery Life

Battery Life

Battery performance is a strong feature, courtesy of a removable 3000 mAh Li-Ion battery. It supports stand-by times up to 936 hours across both 2G and 3G networks, and impressive talk time up to 31 hours and 20 minutes on 2G, reducing slightly for 3G usage. This endurance provides users the confidence of extended usage without frequent recharging, a critical factor for power users or travelers.
