iPhone 11 and iPhone 12 started to discharge and overheat quickly

After the release of iOS and iPadOS 14.6, some users started reporting that their devices were running low on power very quickly. One of the users writes about the fast discharge of the iPhone 11 Pro and Apple Smart Cover.

Immediately after the update, the charge on the iPhone 11 Pro dropped to 2%, and the charge on the Apple Smart Cover dropped to 15%. Usually, the smartphone remains fully charged after an update, and the Apple Smart Cover discharges to 20% after a 15-hour work day without being connected to the network. The battery remains at 100% for over a year. The Smart Cover battery icon no longer appears on the home screen when connected or disconnected.

According to forum posts, the issue affects all devices, regardless of the state of a particular battery. Another user stated that the iPhone 12 Pro not only began to drain faster than usual, but also began to overheat while running Safari. Similar messages came from owners of the iPhone 12 mini.

Yes, I upgraded my iPhone 12 mini from 14.2 to 14.6 a couple of days ago. In the morning I used the smartphone for several minutes, when suddenly the charge dropped to almost zero, and the smartphone itself became very hot.

If the issue is indeed software related, Apple could release a patch for iOS 14.6 or postpone a patch for iOS 14.7, which is currently in beta.
