Building upon the previous version launched two years ago, Wear OS 4 promises battery improvements and a more reliable experience. The new OS aims to introduce “enhancements to security, user customization, and power optimizations” according to the official statement released at Google I/O 2023.

“We're releasing the first Developer Preview of Wear OS 4, the next version of Google's platform arriving later this year”, the official announcement said. It also noted that the new version would enter developer preview via emulator on the same day.

Backup and Restore Support

A much-needed feature, the backup and restore support, is finally coming to the platform. This will allow users to “securely transfer data and settings from an old watch to your new one”, says Google. Users setting up a watch from their phone will find that permissions granted on the phone will automatically carry over to the watch.

Wear OS 4 Watch Face Format and Battery Optimization

The new format is a “declarative XML format to design the appearance and behavior of watch faces” The format eliminates the need for executable code, leading to no code embedded in the Watch Face APKs.

“Wear OS will take care of the logic needed to render the watch face so you no longer have to worry about code optimizations or battery performance” promises Google. This simplifies the design process, reduces the need for maintenance, and minimizes updates.

Integration of Gmail and Google Calendar

Google is also bringing Gmail and Calendar to Wear OS “later this year”. The integration of these services will enhance the overall user experience, allowing users to browse their inbox, read, favorite, and quickly respond to emails.

Expectations and Future Developments

While these updates represent a significant step forward, there are still questions surrounding the transition to Wear OS 4, particularly given the somewhat rocky shift to Wear OS 3. The integration of , Google Calendar, and third-party apps promises to make Wear OS more versatile, but the real success of Wear OS 4 will depend on how smoothly Google handles this transition. However, per the official announcement, further details are expected to be released in the coming weeks and months, making the rest of the year exciting for smartwatch users and developers.
