Apple comes with a proper battery-saving mode for watchOS 9. As promised, Apple has included a proper power-saving mode to the Apple Watch in the latest watchOS 9 updates. The Control panel or the settings menu must be used to enable the feature manually.
There’s a 10% battery warning, too. When it reaches 80% charge while being charged, it shuts off automatically. Battery saving mode disables power-hungry functions, including AoD alerts, heart rate tracking, arrhythmia monitoring, and blood oxygen levels. The workout timer is also disabled.

Interestingly enough, the watch will disable cellular and Wi-Fi connectivity if no nearby iPhone is attached to it. We’ve turned off incoming calls and alerts as well. The system will likely restore your data and Wi-Fi connections if you need to use an app that depends on them.
As long as the watch is within range of the phone, it will delay alerts and only send them once an hour. Even while the watch’s battery life will increase with the new power-saving mode, the overall performance will decrease, making animations and navigation less fluid.
