Today's project: #diy battery for my 2015 phone. Original battery down to 6% of it's original capacity. Replacement battery costs only R90 and is readily available at hobby shops. Had to make an adapter plate using my favourite material: masonite board. Sealed it with a polyurethane coating. I've avoided buying new electronics and am still sticking with my 2015 phone and 2015 tablet as my main mobile devices because they are hackable in this way, and the software (after disabling all the bloat) is still running sweetly.
