On previous generations of iPads, we found that accessing the battery was a much more cumbersome process and took a significant amount of time to access. Repairs are now much easier as the battery can be accessed much earlier in the process. iPad Pro has a smaller battery than its predecessor, but delivers the same 10 hours of performance thanks to the efficiency achieved by the M4 chip. The 38.99 Wh battery is removable without removing any other major components of the iPad itself.
This saves not only disassembly time, but also time for the user to put the device back together. There are also fewer obstacles and challenges, reducing the risk of damage and improper reassembly. Because the iPad Pro doesn't have the internals as easily accessible as, say, a standard laptop, it can be repaired at a professional level, even when it comes to replacing the battery.
The iPad Pro should enjoy a fairly long lifespan thanks to its robust construction and over-the-top hardware configuration with the M4 chip. Some iPadOS users argue that the device is too powerful for that software and would be better off paired with full macOS. This gives the iPad Pro a lot of future potential should Apple choose to spice up the software side and add more features to the iPad in that regard.
We're also amazed by the OLED display on this iPad Pro. This is one of the big improvements along with the M4 chip.
Long-term repairable devices, especially those with easy access to batteries, become more durable technologies. In the same video, iFixit tried to open the Apple Pencil Pro, but couldn't do it in a clean way. At least the iPad passed the test and has some improvements in terms of repairability.
