Battery Life
Equipped with a removable 950 mAh Li-Po battery, the K660 provided a balance between performance and endurance. It promised a standby time of up to 330 hours on both 2G and 3G networks, with talk times of up to 9 hours on 2G and 4 hours and 30 minutes on 3G. This was fairly impressive, ensuring users could rely on their device throughout the day without frequent recharges.
