Battery Life
The Air 4.5 housed a 1700 mAh Li-Ion battery, which proved to be one of the less impressive components of the phone. Offering up to 120 hours of standby on 3G and around 8 hours of talk time, the battery life was fairly limited. For users relying heavily on their smartphones throughout the day, frequent recharging was expected. The device did support music play for up to 24 hours, making it a decent option for media consumption in shorter sessions.
