My iPhone 6S Plus hasn’t been charging properly. I’ve needed to position the cord just right for months. It’s been incredibly annoying. Yesterday I decided to take a toothpick and see if I could get any lint out of it after seeing many posts of this online. It worked! The lint was extremely impacted, but I got it all now. Now it charges perfectly again! This issue was seriously frustrating me, but now that it’s been solved, I’m more okay with keeping this phone for longer. If you’re having problems charging, try this approach first!
