Safety first! Let's get this battery disconnected. The connector is still hidden underneath the battery, but a quick flip from an opening pick takes care of that.

Subtract one tiny tri-point and one teeny bracket and this wee powerhouse is a freed powerhouse.

The 44 mm Watch cell is rated at 1.17 Wh—a slight increase over the Series 5, but not quite at the level of the 1.3 Wh Galaxy Watch3.

The smaller 40 mm Series 6 retains the radical metal-pouch design introduced on the Series 5, now with a 1.024 Wh capacity.

We're a little surprised the larger model still doesn't get the new battery design this year—we thought Watches might follow the pattern set by the iPhone, where Max models got the new battery design in its second year.

Summing up: that's a 3.5% increase for the 44 mm battery, and an even bigger 8.5% increase for the 40 mm from their Series 5 counterparts.

Slowly but surely, Apple Watches seem to be clawing back capacity after the big drop from Series 3 to Series 4.
