Apple iPhone 13: Known Problems

Apple designs the batteries in iPhone 14 models and earlier to keep 80% of their original capacity at 500 complete charge cycles under ideal conditions. If you're charging more and more often, Apple says it might be time to service the battery.

Apple says a dirty or damaged charging port can trigger the "accessory not supported" alert, and its steps for an iPhone that won't charge include removing any debris from the port.

Apple says iOS 15.1.1 improves call drop performance on iPhone 12 and iPhone 13 models. If calls keep dropping, check you're on iOS 15.1.1 or later before suspecting the hardware.

On iPhone 13 models, a screen replaced outside Apple disabled Face ID, because the phone couldn't pair with the new screen. Apple lifted that restriction in iOS 15.2 in December 2021, so update before a screen repair.

Apple's iOS 15.0.1 notes list a fix for an issue where some users couldn't unlock iPhone 13 models with Apple Watch. If your watch won't unlock your phone, update before anything else.

Apple rates the iPhone 13 IP68 to a depth of 6 metres for up to 30 minutes, but says the resistance isn't permanent and might decrease with normal wear. Liquid damage isn't covered under warranty.
