iPhone XS, XS Max Reveals Some Battery Surprises

By Battery Power Staff

September 21, 2018 | iFixit recently broke down the new iPhone XS and iPhone XS Max, revealing interesting details about the mobile devices’ battery capabilities. ZDNet covered the breakdown.

The first interesting revelation is that the iPhone XS has a smaller battery than the one found inside last year’s iPhone X – 10.13Wh compared to 10.35Wh. According to iFixit, the reason for this is that in moving from a design that featured a dual-battery, the iPhone XS uses a single-celled L-shaped battery. In order to create a battery with six corners, Apple had to add notches to the corners to handle thermal expansion, and this in turn reduced the capacity of the battery.

The iPhone XS Max continues to make use of a dual-battery system, and this has a capacity of 12.08Wh.

This gives the new iPhones battery capacity that’s similar to that of the Samsung Galaxy S9 and Galaxy S9+, but nowhere near that of the Galaxy Note 9.
