Every time there is an iOS update my charger or iPhone stops charging properly. The only reason I knew there was an update is because of this exact behaviour and low and behold I check the update and yes there is a new ready to be installed. My iPad took 7 (yes I counted them) attempts before I had to throw it away after Apple said it was the charging port, what a coincidence. However my iPhone they replaced for the exact same reason because I logged the incidents of it occurring, how weird.. I’m near enough certain Apple send something to phones and iPads around the release of iOS updates that does something to the battery sockets, but it’s always to do with the battery! Whether it’s poorer performance or this issue they code something so people have to upgrade their phones. I am sooo over this company, seriously they are bunch of tossers and after this one goes I am out for good!
