Got my 50 bucks last week, a pleasant little something to partially cover battery replacement I paid a 100 EUR for after three years of use. I wish phone batteries were as simple to replace as in 00's. Maybe my next phone will be like that in several years, gonna keep my 4a meanwhile.
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.
