If you have been experiencing battery drain issue on your Apple Watch, then you will be pleased to know that Apple has released watchOS 7.0.2 software update with a fix for this problem.
With this release Apple has fixed the battery drain issue that many users were seen complaining about ever since the release of watchOS 7 back in September. The Apple Watch battery drain issue is also present on the newly released Apple Watch Series 6 and Watch SE.
You can update your Apple Watch to watchOS 7.0.2 by opening the Watch app on your iPhone and going to General -> Software Update.
Once the update has been downloaded on your iPhone make sure you place your Apple Watch on its charger before hitting the Install button. Apple Watch needs to have at least 50 percent battery and placed on the charger before the update can be installed.
In addition to the battery drain problem Apple has also fixed the issue that caused ECG app to become inaccessible even in regions where Apple Watch’s ECG feature is supported.
