Battery Life
A significant highlight of the S660 is its robust Li-Po 3000 mAh removable battery. It provides substantial longevity with up to 36 hours of talk time on 2G networks and up to 20 hours on 3G, making it a reliable companion for users needing a device that can last throughout the day without frequent recharging. This feature, along with its stand-by time of up to 840 hours, was particularly appealing to those valuing prolonged battery life.
