Replacing an iPhone Battery DIY

[@NuggoZE]

Is it possible to buy a bigger capacity battery for a phone if you know how to replace it and take it apart like this?

[@JaysPhoneRepairs]

Ideally you should aim to stick to a reliable supplier of a high quality aftermarket replacement. Often times, the cheap higher capacity batteries are poor quality and a lot of them should be avoided in my opinion

For a provided battery replacement? Which model?
