Can Youtube teach me how to replace my phones battery? iPhone SE battery replacement.

Using only KZbin and with no previous experience I replaced my iPhone battery. It wasn't pretty but I got it to work. I wonder if there are more things that I can learn, save money on by doing it myself from just youtube-videos.
