Internal Battery Specs
Capacity: 3,149 mAh / 12.26 Wh.
Design: Housed in a protective metal enclosure with easy-release adhesive for safety and repairability.
Performance: Lasts through a standard day of moderate use, though heavier tasks or video streaming drain it faster than Pro Max models. [1, 2, 3, 4]
MagSafe Battery Pack
Because of the phone's smaller size, Apple offers a dedicated Apple MagSafe Battery for iPhone Air. [1, 2]
Extra Power: Adds up to 65% additional charge.
Charging Speed: Delivers up to 12W of wireless charging on the go, or faster speeds when plugged into a 20W+ adapter simultaneously.
Smart Behavior: Designed to act as an extender rather than a rapid charger—keeping your phone stable around 90% when attached rather than aggressively pushing a depleted battery straight to 100%.
