Also, iOS 15 now lets you add tags to your notes so users can categories them easily. And another cool feature is Smart Folders which automatically add notes in one place based on your tags which can be very useful for some users.

Tip 1: If your Apple Watch has watchOS 6 or later, then you can install any latest watchOS on your Apple Watch without iPhone, just make sure your Apple Watch has connected with a Wi-Fi network. Follow these steps to update Apple Watch without iPhone, Settings > General > Software Update.

Tip 2: You can use iPhone to update your Apple Watch software. When you see an alert on your iPhone that says “Your Apple Watch software is out of date,” you should update to the latest version of watchOS so that your data, including Activity Data, continues to sync to your iPhone.

Tip 3: You can manually update your Apple Watch, just put your Apple Watch on its charger until the update process has been done. First, open Apple Watch app on your iPhone and go to the My Watch > General > Software Update.
