### Teardown Insights: iPhone Air MagSafe Battery
In the latest teardown of the [iPhone Air MagSafe Battery](https://www.amazon.com/Apple-iPhone-Air-MagSafe-Battery/dp/B0FQFH9BST/?tag=marcmendes-20), iFixIt uncovered fascinating information indicating that Apple might have employed a tactical method to ease production.
#### Overview of the iPhone Air MagSafe Battery
As part of its yearly teardown season, iFixIt analyzed the iPhone Air MagSafe Battery, unveiled during Apple’s “Awe Dropping” presentation. This accessory aims to deliver an extra 65% charge for those who feel the iPhone Air’s battery falls short for all-day usage.
#### Key Measurements
The iPhone Air MagSafe Battery has a thickness of 7.64mm, significantly bulkier than the iPhone Air’s frame, which measures 5.6mm (not including the camera protrusion). This difference prompted inquiries about the battery’s capacity.
#### Investigation into Battery Specifications
Upon deeper examination, iFixIt discovered that the battery contained in the MagSafe accessory seems to be the same as that found in the iPhone Air. Specifically, the actual battery measures 2.72mm in thickness, which fits comfortably within the dimensions of the iPhone Air.
#### Efficiency and Charging Limitations
Regardless of the bulkier design, the MagSafe Battery provides only a 65% additional charge. iFixIt points to this limitation as a result of inefficiencies related to wireless charging, indicating that around 35% of energy could be lost during the charging procedure. Although this percentage might appear substantial, it aligns with the observed efficiency.
#### Conclusion
With the iPhone Air now being distributed to customers worldwide, it remains uncertain whether Apple designed the same battery for both the iPhone Air and the MagSafe Battery or chose a similarly shaped, lower-capacity cell to optimize production.
