Samsung R860 Caliber Battery Life

Battery Life

The device is powered by a removable Li-Ion 1080 mAh battery, which was relatively standard for phones at the time. It provided up to 300 hours of standby time and up to 4.5 hours of talk time, sufficient for a full day's moderate usage. The removable nature of the battery allowed users to carry spares, thus extending usage on the go—a convenience that some modern phones lack.
