Batteries are always maintenance parts. The fact that modern smartphones and notebooks don't make changing them a trivial operation is condemnable. At least you can install new batteries with different form factors now. Technically it would be trivial to just have a lid to install new ones. Profit orientation is worse than customer orientation. It is also an ecological problem. Instead of changing batteries after 2-3 years, people buy new phones.
