Apple’s Smart Battery case for the iPhone 6s receives the teardown treatment

After tearing down the case, iFixit discovered a With 7.13 Whr (1877 mAh at 3.8 V) capacity battery, which should serve to double up the 6.55 Whr capacity of the battery contained in the iPhone 6s.

Just like the Smart Keyboard and the Apple Pencil, tearing down the Smart Battery case is an irreversible destructible process. Prying open the soft microfibre finish in the inside revealed the aluminium sheet on which the microfibre cloth sticks to. The sheet has been heavily scratched to improve the adhesive bond. There is also a mesh interfacing to make sure that there are no fatigue damage on the silicone hinge.

Removing the aluminium sheet gives one access to the 1877mAh battery and its logic board. The battery has been strongly glued in its place to improve the rigidity of the case. The logic board connected to the battery is very small and only contains a few ICs related to charging and load switching.

The highly polarizing case has been the subject of many a debate regarding Apple’s design principals, among other things. I can’t remember the last time that Apple released an accessory that resulted in so much disdain and disrespect. Even Apple CEO Tim Cook felt the need to defend the case’s existence.

In the end, iFixit gives the Smart Battery Case a 2/10 repairability score, which pretty much means that the case is not user repairable at all. If it breaks, or has issues, you’ll likely need to outright replace the case instead of hoping to swap out the battery or other parts. Of course, a low repairability score isn’t desirable, but for a case like this, it’s not at all surprising.
