Some older iPhones, battery drain after installing iOS 14.2

After installing the iOS 14.2 update on some models of Apple’s older iPhones, it is causing serious battery consumption problems, reported by foreign media such as McRumus on the 6th (local time).

According to a post posted on the Apple developer forum and online community Reddit, the battery over-consumption problem seems to occur in most older iPhones, such as iPhone XS, iPhone 7, iPhone 6S, and first-generation iPhone SE.
Users mainly report faster battery drain and longer charging times. Some users reported that the battery life was reduced by 50% in 30 minutes, and there are reports that the battery is reduced by about 5% in just a few minutes.

The iOS 14.2 update, which Apple released earlier last month with the release of the iPhone 12 Mini and iPhone 12 Pro Max, adds more than 100 new emojis to the iPhone and provides eight new wallpapers. In addition, it supports the iPhone 12 MacSafe leather case and supports optimized battery charging that can slow down battery aging by reducing the usage time after the AirPods are fully charged.

In addition, a problem in which the viewfinder may appear black when running the camera has been fixed, and a number of other bugs have been fixed in addition to the problem of losing touch when attempting to enter a password with the keyboard from the lock screen.
Since then, Apple has released the iOS 14.2.1 update, but there are no new reports that the battery issue has been fixed.
