Love it or hate it, there is no way you can ignore Apple’s Smart Battery case for the iPhone 6s.
The case has led to Apple and Jony Ive receiving a lot of flak for
releasing a product that does not live up to Apple’s design standard.
While from the outside, the Smart Battery case does not look like a product made by Apple, how does it look from inside? iFixit tore it down to find out.
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.
In the end, the iFixit team gave the Smart Battery case for the iPhone 6s a repairability score of 2 out of 10. It notes that while replacing the battery is possible, it will likely destroy the inner microfibre lining.
