Hi! I have two iPhone 12 mini and one SE (work phone) and when they’re charging, they do an awful high pitch noise. It’s worse between 80% and 100%. It is so bad that we have to plug them outside of the bedroom. The sound is not loud but very annoying.
do you have suggestions to help me out? We tried different chargers, cables, from Apple and aftermarket.
thanks!
iPhone 12 mini, iOS 14
Hello and welcome to Apple Support Communities, DubinskiCanada!
We understand you're hearing a sound coming out from both your iPhone 12 mini and your iPhone SE while charging. We'd be happy to provide information to help you address this.
Test to see if this same sound occurs while plugged in to a different outlet. Also, check to see if this happens while connected to a computer. The article for when your iPhone won't charge, may help: If your iPhone or iPod touch won't charge
If you don't hear this while charging with a computer, check to see if changing the adapter stops the sound.
Have a great day!
