Moving swiftly along, we take a closer look at the Mate's power plant.

To our surprise, we find some orange pull tabs on the left side of the battery, containing a short guide how to remove it—we love guides!

We're happy whenever we can extract a battery without having to break out our iFixit Adhesive Remover—in this case, we just needed a little help from an iOpener to unseat it.

The battery weighs in at an unprecedented 16.04 Wh (4,200 mAh at 3.82 V).

In terms of raw capacity, that beats just about everyone—including its predecessor (15.28 Wh), the iPhone XS Max (12.08 Wh), and even heavyweight Samsung Galaxy Note9 (15.4 Wh).
