The iPhone 16 made battery replacements slightly easier, but that didn't translate to cheaper prices on battery replacements (they're $100 now).
You still need to heat up the adhesive to remove the back glass (at least you don't have to disassemble the entire phone out through the front anymore), and the new trick with the 16 is that once you're inside the battery is mounted with an adhesive that can be loosened by hooking up a 9V battery for 90 seconds.
