Apple seeded iOS 14 and watchOS 7 to the public a few weeks ago and as good as they are, there are bound to be certain issues. Initially, operating systems are buggy at first and need fixes through subsequent updates. While Apple is potentially working on their fix for good, for the time being, the company recommends alternative measures that might not be ideal. Apple is now suggesting users to restore their iPhone and Apple Watch if they are experiencing excessive battery drain issues or missing GPS data.

Several online support threads have reported that GPS data was being properly recorded during activities on the Apple Watch. Moreover, all models have been affected. Other than this, on the iPhone, iOS 14 seems to be draining a lot of battery more than usual. The excessive battery drain issue is also present on the Apple Watch running watchOS 7. Potentially as an official fix, Apple suggests users to restore their iPhone and Apple Watch to fix the battery drain and other issues.
