iPhone Air MagSafe Battery Pack Teardown Reveals Clever Reuse of Internal Parts.Apple launched its ultra-thin iPhone Air last month. The new design required a special MagSafe Battery Pack accessory. A new teardown of that battery pack reveals its internal secrets. The findings show Apple’s clever engineering approach.The teardown was performed by the repair experts at iFixit. They discovered the battery pack uses a cell identical to the phone’s own battery. This strategic reuse highlights Apple’s design efficiency for its new product line.
Identical Battery Cell and Wireless Charging Limits
The MagSafe Battery Pack contains a 12.26 Wh battery. It is remarkably thin at just 2.72mm. This allows it to fit seamlessly with the iPhone Air’s 5.6mm profile.According to iFixit, the cell is the same one powering the iPhone Air itself. It shares the exact same shape and thickness. This repurposing of an existing component is a smart manufacturing move.Apple states the pack charges the iPhone Air to 65 percent. This is due to inherent energy loss from wireless MagSafe charging. A significant amount of energy is lost as heat during the transfer process.
Design Compromises for a Functional Accessory
The internal battery is protected by a plastic casing. It lacks the metal reinforcement found inside the iPhone itself. However, the plastic is notably thick for added durability.This construction makes the battery pack thicker than the iPhone Air. iFixit believes this was a necessary design choice. Apple prioritized creating a functional accessory over matching the phone’s extreme thinness.Ultimately, the accessory offers a neatly packaged power solution. It will not transform the iPhone Air into a multi-day device. But it provides a convenient boost for users on the go.
The iPhone Air MagSafe Battery Pack teardown confirms strategic component reuse. This approach by Apple balances innovative design with practical manufacturing. The $99 accessory remains a niche but clever solution for the world’s thinnest phone.
Info at your fingertips
What is the capacity of the MagSafe Battery Pack?
The battery pack has a 12.26 Wh capacity. This is the same capacity as the battery inside the iPhone Air itself.
Why does it only charge the phone to 65%?
Wireless MagSafe charging generates significant energy loss. This efficiency loss prevents a full 100% charge from the pack alone.
Can you charge the battery pack with a cable?
Yes, it features a USB-C port for wired charging. This method is more efficient and faster than wireless charging.
Is the battery pack compatible with other iPhone models?
It is designed specifically for the iPhone Air’s form factor. Compatibility with other models is not officially supported by Apple.
How thick is the MagSafe Battery Pack?
The pack is thicker than the iPhone Air. This was a deliberate design choice to ensure durability and functionality.
