The iFixit gang tears down the 2016 Retina MacBook

The gang at iFixIt, which tears stuff apart and looks at it so you don’t have to, have disassembled the 2016 MacBook and looked at its innards. It’s pretty much identical to the 2015 model.

You should check out the complete teardown, but here are some of the highlights:

This MacBook comes with an additional hour of battery life. The iFixIt gang says they’re tempted to attribute this boost to increased efficiency from the sixth-generation Intel Core M processors and a small bump in battery capacity, surpassing the 2015 MacBook with 41.41 Wh at 7.56 V—over a 4% increase. This increased capacity seemingly comes without changing the form factor of the battery.

The USB-C hardware changed from the 2015 model. It looks like they moved some silicon from the USB-C connector cable onto the USB-C board, and permanently affixed the cable to the board to make the components a single unit.


There’s been lots of hoopla about increased SSD speed, which the iFixIt gang suspects is due to a new iteration of Apple’s in-house, TSMC-fabricated SSD controller. On the 2015 Retina MacBook, the controller was layered beneath the SK Hynix H9TKNNN4GDMRRR-NGM LPDDR2-SDRAM. But on the 2016 MacBook, it’s sitting by its lonesome with a slightly new model number: 338S00066 vs. 338S00055.
