iFixit discovered some more new things on the 2018 MacBook Pro 13-inch.
The 2018 MacBook Pro 13-inch has a larger and heavier battery. However, the MacBook doesn't have longer battery life compared to the 2017 model.
Second, Apple includes a redesigned power adapter with the 13-inch MacBook Pro. The model is now called A1947 and offers more shielding and impact-resistant foam rubber inside, but with a plastic USB-C port rather than a metal one, according to iFixit.
The 13-inch MacBook Pro 2018 also has a 'tweaked top case', meaning that Apple "shaved some mass" from the top case.
Lastly, the device has longer and narrower speakers, bumping right up against the logic board.
