The teardown reveals a larger battery with a 58.2 Wh capacity, which slightly exceeds the 54.5 Wh battery found in the previous-generation function key model. iFixit guesses this is how the 2019 model manages to power the Touch Bar, Touch ID, and T2 chip while keeping the same 10-hour battery life.
To make room for the Touch ID sensor alongside the Touch Bar, iFixit notes that Apple appears to be using a slightly smaller heat sink. The speaker opposite the fan also looks to have been shrunk in size.
While the previous-generation entry-level 13-inch MacBook Pro had a modular SSD, storage is soldered down in the 2019 model. However, there are some newly modular components, including the Thunderbolt board and the speakers. This configuration is in line with other modern MacBook Pro designs.
As we confirmed earlier this week, the notebook has the same third-generation butterfly keyboard with updated material as the higher-end 2019 MacBook Pro models introduced in May, with Apple promising improved reliability.
Like most other modern MacBooks, this model earned a low repairability score from iFixit due to the usual concerns, such as Apple’s use of proprietary pentalobe screws, a glued-in battery, and soldered-down storage and RAM. One positive is that the trackpad can be replaced without touching the battery.
