Battery Performance
Battery life is one of the standout features of the OT-355. Equipped with a removable 650 mAh Li-Ion battery, it promises substantial longevity. Users can expect up to 450 hours of standby time and up to 9 hours of talk time, which is impressive even by modern standards for a basic phone. Music playback is supported for up to 17 hours, providing ample entertainment between charges. The removable nature of the battery remains a favorable aspect for those who preferred the option to carry a spare.
