The new MagSafe Battery for iPhone Air might seem like a misstep, but it makes perfect sense for two reasons.

Control and optimization.

The iPhone Air is the first iPhone to have all chips be Apple-designed chips, giving them unprecedented control of Wi-Fi, Bluetooth, Thread, and cellular efficiencies. The Apple-developed A19 Pro can talk to the N1 network processor and the C1X cellular modem at a more optimal level, maximizing battery and function based on multiple factors.

If Apple made a single battery pack for all new iPhones, it would be a more generic experience across the board since the iPhone 17 lineup still uses a 3rd party Qualcomm modem. The Battery Pack wouldn’t meet Apple’s standards of true optimization. It would still be better than a generic 3rd party battery pack that just destroys battery health, but this unique, intimate relationship with the MagSafe Battery and the iPhone Air makes it outlast the iPhone 17 Pro Max at 40 hours of video playback vs 39 hours, making the combo the best battery life of any iPhone to date.

Remember - Love is in the Air.

Who knows, maybe in the future when all iPhones have Apple-designed chips, Apple could go back to making one MagSafe Battery Pack that is optimized across the board.
