Here are the features that come with the new battery saver mode:
With the new update, after the Apple Watch enters power saving mode, the Always-On Display automatically turns off more power-consuming functions on the Apple Watch, such as arrhythmia, high heart rate and low heart rate notifications, heart rate and blood oxygen measurements. . In addition, your Apple Watch will notify you when it has 10% remaining charge, while it will automatically exit battery saver mode when its charge reaches 80%.
If the Apple Watch doesn’t have an iPhone connected nearby, the power saving mode will also automatically turn off the smartwatch’s Wi-Fi and cellular network data connections, incoming calls, and app notifications. Of course, if you need a particular app that requires data or Wi-Fi connection, the system will re-enable them.
In addition to turning off the above functions, Apple Watch will also optimize other functions such as lowering the refresh rate of Siri and background apps to further reduce power consumption after entering power saving mode.
