Not on iOS 14.2 yet? Might want to wait for the next update, because this one causes severe battery drain
Since iOS 14.2 is available for a wide range of devices, it is not surprising to see that what appears to be a software bug is hitting both older and recent iPhone models, and even some iPad Pro tablets. According to multiple user reports, the problem has two nasty sides that translate to rapid battery drain and longer charge times.
The aforementioned reports surfaced on both Reddit and the official Apple Developer forums. Some of the users whose devices are affected by these problems report a 50 percent charge loss in under 30 minutes, as well as 5 percent drops within minutes of regular use. The problem is certainly software-related, because battery life sits at high percentage values before dropping and also there is a noticeable gain after restarting the device.
The list of affected devices includes older models like the first-generation iPhone SE and the iPhone 6S, but the iPhone 12 and iPhone 12 Pro also seem to be in the list of victims. The 2018 iPad Pro is also suffering from the same problems.
Since the third developer and public beta versions of iOS 14.3 and iPadOS 14.3 have been released already, it would not be surprising to see the battery drain problems solved without much fuss.
