Battery Life
The Nokia T7 was powered by a removable 1200 mAh Li-Ion battery (BL-4D), providing up to 360 hours of standby time in both 2G and 3G, and talk times extending up to 5 hours and 20 minutes on 2G and 7 hours and 45 minutes on 3G. These figures reflected an optimization balance between performance and battery endurance typical of the era, especially given the power consumption habits of the Symbian OS and the less demanding hardware parameters compared to today’s smartphones.
