If your iPhone battery drains too quickly from iOS 14 or you lose health or wellness data from your Apple Watch, it may be necessary to reset your device to its factory settings.
A few years ago, the battery life of an iPhone was not that long. With Generation 11, however, Apple has changed the game: it is now one of the most enduring smartphones on the market. So when an update reduces radically this autonomy, users notice it. iOS 14 and watchOS 7 for the Apple Watch appear to be causing some problems for some users. On a support page, Apple lists them: fast draining of iPhone battery, apps that won't launch on Apple Watch, loss of data in health or sports apps.
How to fix issues on iOS 14 and watchOS 7
To correct them, while waiting for a patch that will perhaps correct them automatically, Apple offers a rather long procedure.
- Unpair iPhone and Apple Watch.
- Make an iCloud backup of the iPhone, making sure that the health data is backed up.
- Reset iPhone (settings, data and content).
- Restore iPhone from iCloud backup.
- Pair iPhone and Apple Watch again.
If you experience any of the symptoms described by Apple, it is therefore necessary to reset your iPhone to factory settings. The process can be long, especially the backup and restore part, which will need a good Internet connection to move forward.
In our testing of iOS 14, since the early beta, we've seen the battery drain very quickly – sometimes, in just over an hour, at a percentage per minute. These bugs were never related to Apple Watch, however, but mostly to apps running the iPhone's GPS in the background – the misfortune happened to us with CityMapper and Google Maps. But these beta release issues are part of the contract with the testers, who are using unfinished releases knowingly.
We haven't seen any battery drain after updating to the consumer versions of iOS 14 and watchOS 7, but there have been enough social media testimonials for Apple to respond.
Also, consider updating to iOS 14.0.1 which already corrects some problems.
