Battery Life
The One A9s is powered by a non-removable 2300 mAh Li-Ion battery. Although not particularly large by modern standards, it manages to provide reasonable standby and talk times, boasting up to 432 hours of standby time and up to 13 hours of talk time on a 3G network. The device supports 10W wired charging, which is adequate given the battery size, but it might fall short for users who require rapid charging solutions.
