Battery and Performance
Under the hood, the Siemens ME45 is powered by a removable Li-Ion 840 mAh battery, delivering a standby time of 60 to 300 hours and a talk time of 100 to 300 minutes. These battery life metrics reflect its efficient use of energy, largely due to the monochrome display and basic feature set, making it a reliable companion for long durations away from a power source.
