iPhone Air battery also used inside Apple’s MagSafe Battery pack — iFixit teardown
iFixit’s teardown of Apple’s MagSafe Battery pack for the iPhone Air (sold around €115) reveals a surprising discovery: the external battery pack contains a battery cell that appears to be the same model used inside the iPhone Air itself.
Key findings
- Cell: ~3,149 mAh (≈12.26 Wh).
- Cell thickness/shape: a thin 2.7 mm cell matching the iPhone Air’s internal battery design.
- Pack performance: provides roughly an additional ~65% charge to the phone, likely limited by wireless charging inefficiencies.
- Pack size: the battery pack is thicker than the phone but houses a thin cell inside a steel shell with supporting electronics.
What this means
This appears to be a deliberate manufacturing choice by Apple — reusing the same battery design for both the phone and the accessory likely simplifies production and supply chains. For users, it means the MagSafe pack won’t fully recharge the iPhone Air, but it’s a compact option optimized for compatibility.
