Battery Life
The GSmart M3447 is powered by a removable Li-Ion 900 mAh battery. While the capacity appears limited, it provides acceptable performance given the phone's relatively low-power requirements. Users can expect up to 450 hours of standby time on 2G networks, reducing to up to 200 hours on 3G, while talk time extends to roughly 4 hours and 30 minutes—adequate for basic daily use.
