I’ve got a iPhone 16 that is only just over a month old (bought 25th Sept 2026). I only use Apple products to charge my phone - the wall socket and an Apple lead that came with the phone. Recently I’ve been getting “this accessory used too much power” alert on my screen with the blue “OK” button. Sometimes I can press the button, other times the messages pops up and disappears quickly, but continues to do that.
Originally I was using an Apple charger (that was slightly older but no damage etc) plugged into an extension lead. That was when the alert first happened. Then I changed to my newest charger in a different room and plugged it straight into a wall socket. It works for a couple of days and then I got the same message.
I had issues with my last phone (iPhone 17 that was only 6-7 months old) and I was getting the liquid detection alert along with the alert noise. This happened early hours of the morning. So now I always charge my phone before I go to bed, not during the night.
I went to Apple about this but felt dismissed.
Can anyone help me?
