I changed out the battery on my iPhone 6S, and it’s worked great for 3 weeks and now suddenly it won’t take a charge. :/ and ideas?
It could be multiple issues. Check the charging port for debris like Lint. It could be the charging port. It could also be the tristar chip. I would also try a different charger. I would recommend taking it to a repair shop and have them check the tristar chip, it’s simple test .
