Battery Life
A removable Li-Ion 940 mAh battery powers the KX-TU311, providing up to 280 hours of standby time and up to 4 hours of talk time. These specifications should cater to a full day of basic usage, aligning with the expectations from a traditional mobile phone. The removable battery offers the added convenience of swapping out for a new one, should the need arise, extending the phone's operational life.
