According to daily news, Apple pushed the watchOS 9.5.2 update (build number: 20T571) to Apple Watch users today. This update is 22 days after the last release.
It should be noted that due to the configuration cache of Apple’s regional node servers, there may be a slight delay in the detection of the upgrade update in some places, usually within half an hour, not too long.
After the profile is installed, watchOS 9.5.2 can be downloaded through the dedicated Apple Watch app on iPhone by going to General > Software Update. To update to the new software, the Apple Watch needs to have 50 percent battery charge, be on a charger, and be within range of the iPhone it’s paired with.
Apple did not provide an update log for watchOS 9.5.2. Given that Apple has focused its development on watchOS 10, the updates released this time are not expected to be updated much.
