Apple today seeded the first beta of an upcoming watchOS 9.1 update to developers for testing purposes, with the new beta coming just one day after the launch of watchOS 9.
To install watchOS 9.1, developers will need to download the configuration profile from the Apple Developer Center. Once installed, watchOS 9.1 can be downloaded through the dedicated Apple Watch app on the iPhone by going to General > Software update. To update to new software, an Apple Watch needs to have 50 percent battery life, it must be placed on the charger, and it needs to be in range of the iPhone.
We don't yet know what's included in the watchOS 9.1 update, but watchOS 9 brought a redesigned Compass app, a new medication tracking feature, updated watch faces, improvements to Workouts, new features for the ECG app, and more.
We'll update this article if anything notable is found in the watchOS 9.1 update.

Since I updated to watchOS 9 on my SE watch, the battery at the end of the day is far worse. I'd easily have >50% at the end of the day and last night it was like 20%. It's only been a few days so I'm keeping track. I know .0 versions with Apple typically have terrible battery life.
I'm seeing the same thing. Normally I would have about 40-45% left at the end of the day but now I'm down to about 20-25%.
I hope they fix the OS9 tiny illegible complications! World time was a glance; now it's a squint and hold the watch to face. Major step backwards. See the image, OS9 left / OS8 right
