Siemens SL45 Battery and Performance

Battery and Performance

The Siemens SL45 came with a removable Li-Ion 540 mAh battery, offering a standby time of 60 to 170 hours and a talk time of 1 to 4 hours. While these figures appear modest compared to today's smartphones, they were quite reasonable given the device's limited power consumption and functionality. The removable battery was a standard feature at the time, ensuring convenience for users needing extended use on the go.
