But that’s because instead of using a single large cell (like the iPhone 7 battery case’s 2,365mAh battery or the iPhone 6 case’s 1,877mAh), Apple is using two battery cells wired in series, which keeps the net amperage the same but lets it boost the voltage to 8.7V, dramatically higher than the estimated 3.8V that the older cases output power at.

The total power output in Wh (1 Watt = 1 Volt x 1 Amp) for directly comparing the three Apple cases: 10.1 Wh on the new case, compared to 7.13 Wh on the original iPhone 6 model, and 8.98 Wh on the iPhone 7 version.

Most of the case is solid, but the top portion is flexible, just as it was before. On the other hand, the lower portion has a different shape than the previous model. It drops the chin that used to sit below the bottom of the phone, now fitting much tighter.

The Apple’s battery life is estimated estimate is similar to the XS and XS Max. Apple is claiming up to 75 percent extra usage time for these new battery cases. These new battery cases feature physically bigger humps than the earlier versions.
