Why can't my iPhone Charge to 100%?

Episode 1583 (33:11)

Mike from Portland, Oregon
 Apple battery case.

Mike has an iPhone and is using the Apple battery case. But he can never get the charge up to 100%. What gives? He took it to the Apple Store and the geniuses want him to reset, then set it up from scratch. Rich says always set up a phone from scratch, rather than restore the apps from iCloud. And if there's an app that's draining the battery, users are more likely to recognize it from scratch, rather than restoring from iCloud. But Rich also recommends looking to see if Mike's battery is affected by the recent recall. He can also go into the battery health and see which apps are using the battery the most.
