When we use the Apple Watch low power mode we will be able to extend the battery life as much as possible. Let’s be honest, Apple Watch was never known for having a long battery life. Apple Watch Ultra is capable of achieving longer battery life. However, with watchOS 9, the company added a new low mode feature with it to help avoid having to charge your Apple Watch too often.
Back in the day, Apple Watch had a power reserve mode that turned off all features except the time, basically making our smartwatch clunky until we could plug it into a charger, but it does save battery life.
But this new mode is different, because when it is activated, we will still be able to use the Apple Watch, although some functions that consume too much energy will be limited.
What is it for?
This mode disables the always-on display and limits sensor readings such as background heart rate and blood oxygen monitoring. It will also disable irregular heart rate notifications as well as high and low heart rate notifications.
However, if we are in the middle of a workout, the heart rate and GPS will not be affected. In the future, another option that reduces heart rate and GPS sampling is in the works, although it is not currently available.
Use low power mode on Apple Watch
The easiest way is through the Control Center. We will have to swipe up to access it, then we will look for the battery percentage tile and touch it.
We should see a reading of how much battery is left. Click on the Low consumption mode button to activate it. We are going to see a brief explanation about the functions that will be disabled.
From here we can press Activate or Activate to… The first one will enable the mode for an indefinite period. While the last one will allow us to turn it on temporarily: one, two or three days.
