Safely shucking the casing finally gives us a good look at the biggest battery of the day.

Spoiler alert: it's still tiny.

This 3.81 V, 1.52 Wh lithium-ion cell has roughly 16 times the power capacity of the ones we dug out of the AirPods' stems—meaning you should be able to top them up at least a few times between case charges.

For the sake of scorekeeping, the battery in the Apple Pencil weighs in at 0.329 Wh, and the Series 2 Apple Watch sports a 1.03 Wh cell—so this is technically the biggest tiny battery we've recently encountered.
