The new 13-inch M4 iPad Pro is really, really thin. That’s inevitably going to make certain aspects of repairing the device even more difficult, which iFixit confirmed in a teardown published this weekend. But it does shine in one area — when it comes to replacing the battery, Apple made some seriously helpful changes.

“For the first time in an iPad Pro, we’re able to remove the battery immediately after removing the screen,” Teardown Tech Shahram Mokhtari wrote in a blog post. Mokhtari notes that “immediately is relative,” as there are still some screws and brackets to remove before the battery can be taken out, and the video documenting the process shows it takes a bit of work to get to the pull tabs beneath the batteries, but the new setup still shaves hours off the process compared to earlier models.

“The fact that you can remove the battery without having to remove every major component inside this device is still a huge win for repairability,” Mokhtari says in the video. “It’s a massive improvement over the previous generation.” Everything else, on the other hand, is going to be pretty tricky to repair without causing damage. “From the daughterboard to the speakers and coax cables, we found a whole bunch of stuff that’s glued down because there just isn’t enough space for screws.”

And, the teardown shows the new Apple Pencil Pro is a repairability nightmare. Mokhtari — who got cut by the Pencil while trying to get to its insides — called it “a disposable piece of crap once the battery dies.
