Battery cells redistributed throughout housing
The crew at iFixit has dissected Apple's new 13-inch Retina MacBook Pro, revealing the internal changes necessary to achieve its thinner profile. The redesigned notebook takes inspiration from its larger counterpart, transitioning to soldered RAM that cannot be easily swapped at a later time. Users are currently limited to 8GB of RAM, without the 16GB option offered with the 15-inch model.
Interestingly, despite the variety of efforts to shrink and rearrange internal components to reduce size, Apple left unused space around the SSD storage. It is unclear if the company originally planned to offer additional storage choices beyond the SSD-only options.
The modular battery includes several cells beneath the palm rests to the left and right of the trackpad, and a longer cell that crosses beneath the keyboard. iFixit suggests it took only 15 minutes to remove the battery, which was much easier to remove than the battery in the 15-inch model, though the teardown team points out that it is a "far cry from the no-adhesive MacBook Pro batteries of yesteryear."
iFixit ultimately gave the 13-inch Retina MacBook Pro a repairability score of just two out of 10.
