Battery and Color
Powering the Siemens U10 is a removable Li-Po 800 mAh battery, known as the EBA-010, which supports up to 120 hours of standby time and around 1 hour and 20 minutes of talk time. Given the power demands of early 3G technology coupled with its feature set, this battery life was fairly typical, though it necessitated regular charging for active users. The phone was available in a titanium color, aligning with its business-oriented design and appeal.
