Disable the Wi-Fi and WalkieTalkie on your Apple Watch
Two things that consume battery power are being connected to a Wi-Fi network and having your WalkieTalkie enabled. To disable Wi-Fi you have to go to Settings from your watch and disable it. For WalkieTalkie, you have to go to the App that has the same name and slide the switch so that it is not green.

Minimize Apple Watch notifications that are not useful to you
Another option to save battery is to only enable the notifications that you really need on your watch. That is, you can disable all the notifications from apps that are not essential on your Apple Watch, so they won't waste your battery.


Remove the apps that consume the most power from your Apple Watch
Similarly, a very practical way to save your battery is to reduce power-hungry applications. If you have several installed on your device, your battery will notice it. Only keep the apps that consume the least amount of power. You can even delete native apps that you don't use to minimize background battery and storage consumption.

Disable environmental sound measuring
The Apple Watch is in charge of our health, including our hearing. However, this check causes the Apple Watch to continuously measure the noise level of the environment you are in. Disable this option to save battery life. Go to Settings> Noise> Environmental Sound Measurements to turn this feature off.

Turn off always-on display mode
If you have an Apple Watch Series 5 or later, you have an always-on display. This screen ensures that your Apple Watch always tells you the time, even if you haven't turned your wrist. If you want to save battery life go to Settings> Display & Brightness> Always On and turn the feature off.

Hey Siri consumes battery on your Apple Watch
Siri is there whenever we need her. For a few years now, you can say Hey Siri and talk directly to the screen of your Apple Watch, and even talk without saying Hey Siri. Still, we recommend you to disable all the options except "Press the digital crown". To do this, go to Settings> Siri.

Set the power saver mode
Your Apple Watch has a battery saving mode that drastically reduces consumption without reducing usage. It will ask you to activate it automatically if it reaches 10% battery, though there is a way to enable it earlier. You just need to do the following:
1 - Open the Control Center by swiping upwards on the watch face.
2 - Tap the battery percentage.
3 - Tap Save battery > Continue.
