We disconnect the battery without any drama—it's buttoned down with a T5 Torx screw, so we use one of our blue and black Pro Tech specialty drivers to dispatch it.

At 58.0 Wh, this battery has gotten a significant boost over the 49.2 Wh unit we found in our original 13" Touch Bar teardown.

Turns out that extra 'oomph' comes from a slightly bigger battery—arrayed into six cells this time, instead of five. It's also heavier, weighing in at in at 232.7 g, versus the old battery's 196.7 g.

And yet this MacBook Pro's total weight hasn't changed one iota. We're not sure which parts of this device have been on a diet, but it does look like Apple shaved some mass off the top case.

Despite all that, Apple still rates battery life the same as the prior model. Those extra processor cores don't come for free.

The new-and-improved speakers (on the right) have grown, too—they're longer and narrower, filling all the remaining space, and bumping right up against the logic board thanks to the revised top case design.
