Battery Life and Other Features

The device is equipped with a non-removable 2730 mAh Li-Ion battery. While it might seem underwhelming by today’s standards, it efficiently powers the device through a day of moderate use, thanks in part to the energy-efficient components and modest screen size. Sensors including an accelerometer, proximity, and compass contribute to the phone’s basic functionality, although modern biometrics like fingerprint scanning are omitted.
