Apple M4 iPad Pro Teardown Reveals A Major Change For DIY Repairs
During a teardown by the popular DIY proponent iFixit, the access to the battery was surprisingly improved from previous generations. One of the few user changes possible to the complex internals is the battery itself, so the ability to swap it out down the road is a big benefit. This teardown was done on the larger 13-inch iPad Pro, which has more internal room for organizing the various components in a more accessible fashion.
This saves time in disassembly, as well as when the user goes to put the device back together. It also presents less obstacles and challenges, reducing the risk of damage or improperly done reassemblies. The iPad Pro is still an expert level repair even for a battery swap, since the internals are not as easily accessed as something like a standard PC laptop, for example.

We can also marvel at the OLED display within this iPad Pro, which is one of the other major improvements together with the M4 chip.
Having a long-term repairable device, especially with the easier battery access, will make this a more enduring piece of technology. In the same video, iFixit attempts to open up the Apple Pencil Pro, and fails to do it in a clean way. At least the iPad passes the test - and has some improvements for repairability.
