Smartwatch Battery Life – 10 Ways To Make Wear OS Battery Last Longer

Smartwatch Battery Life – 10 Ways To Make Wear OS Battery Last Longer

Some people say that a gadget is only as good as its battery life. For the most part, that statement could be true. I don’t know about you, but I usually like to use a gadget’s to its full potential. All my gadgets are loaded with apps, files, and are always connected, not to mention I use them all throughout the day. This where smartwatch battery life becomes an issue.

Some of the top smartwatches today run on Google’s popular Wear OS (previously Android Wear). For most Wear OS smartwatches, battery life usually lasts a minimum of 1 day. Depending on how you use your smartwatch, you may or may not have difficulty getting the battery to last the whole day. But unlike our smartphones, smartwatches are usually more of a hassle to charge due to the more bulky chargers.

This brings us to the problem of how to prolong your smartwatch’s battery life so that it lasts until the end of the day, or at least until you get home. Don’t worry though, as I’ve put together this list of 10 ways to improve your Wear OS smartwatch battery life.


  1. Turn down the brightness

There are a couple of adjustments you can do to a smartwatch’s display that can improve battery life.

Unsurprisingly, when you want to save battery life on gadgets like smartphones and smartwatches, turning down the brightness is usually what comes to mind first.

Try turning cutting the brightness level into half, or you could even turn the brightness down to the lowest possible level. However, this will obviously result in some visibility problems, especially if you’re outside and it’s a sunny day.

But if you want to save power, this can easily extend your smartwatch’s battery life by a couple of hours.

Here’s a helpful article by Google to help you more with this.


  1. Turn off the Always On display

The second adjustment you can do to your smartwatch’s display that will improve battery life is to turn off the Always On feature.

This is easily one of my favorite features in both smartwatches and smartphones, and one that I will always look for.

However, having this feature on means extra work for your smartwatch, so it will drain power pretty fast. So if you can live without it, it may be a good idea to turn it off and save the battery life.

This is another simple and easy adjustment that could easily give you a few more hours of battery life.


  1. Limit your smartwatch’s connectivity

Your smartwatch has built-in features that allow it to connect to your smartphone or the internet. With that being said, most of the useful features that make smartwatches great rely on being connected either to the internet or your phone. However, connectivity is also one of the things that drain your smartwatch’s power fast.

Think about limiting your smartwatch’s connectivity. Turn off features like Bluetooth, Wi-Fi and NFC whenever you don’t need it, this way you can save a significant amount of battery life.

Although this somehow limits the ways you can use your smartwatch, this can potentially double the battery life on your smartwatch.


  1. Block notifications from some apps

Showing you notifications is one of the most useful features that a smartwatch has. However, too many notifications will take a toll on your smartwatch’s battery life, as the screen needs to wake up a lot.

In order to save battery life, try blocking notifications from some apps. With Wear OS, you can block some notifications which you think are not that important, and require less attention.


  1. Disable the Tilt to Wake feature

The Tilt to Wake feature wakes your watch up every time you move your arm and tilt the screen towards you. This means you don’t need to use your other hand to wake your watch up, which makes it pretty effortless. It’s really great for situations where your other hand is busy, or if you’re just lazy like me.

However, there may be times when your smartwatch wakes up after you move your hand, even when you were not trying to look at the screen. This will obviously drain power quickly.

If you can live without this hands free feature, consider turning it off and save a considerable amount of battery life.


  1. Turn off Google Assistant voice detection

Google Assistant is another great and useful feature for the new Wear OS smartwatches. While it may help you with a lot of your tasks, it can negatively affect your smartwatch’s battery life.

To do its job right, Google Assistant keeps listening for that “OK Google” command. Unsurprisingly, this requires power, which means it will keep draining your smartwatch’s battery life for as long as it is kept on.

Turn this feature off and give the sound sensor a break, and at the same time improve your smartwatch’s battery life.

Here’s another article by Google to help you with this.


So far I’ve given some simple methods to save battery life on your smartwatch. These next tips are a little bit more extreme (I can’t think of a better word for it), but will definitely save you a significant amount of battery life.


  1. Mute notifications entirely

You have the option to mute notifications entirely, to save power. I don’t know why anyone would ever want to do this, because I think displaying notifications on your smartwatch is incredibly useful, but you can if you really want to. Turning off notifications on your smartwatch entirely will definitely give you a few extra hours of battery life.


  1. Turn on Airplane Mode

Switching to Airplane Mode is a pretty extreme measure in my opinion, but it is definitely a good option if you’re looking to save a great amount of battery life.

With Airplane Mode switched on, most of your smartwatch’s functions will not be useable. Connectivity will be completely cut off, so you cannot use Bluetooth, LTE, Wi-Fi and NFC. This also means that you won’t be getting any notifications.

This severely limits your smartwatch’s functionality and the ways you can interact with it, but the battery life will most probably last a couple of days longer if you keep this mode on.

  1. Hibernate your smartwatch

Other than completely turning off your smartwatch, this is probably the ultimate measure to save battery life. As you might have guessed, you can’t do a lot with a hibernated smartwatch, and at this point it’s basically just a fancy bracelet.

But only a tiny amount of power is drained when a smartwatch is hibernated, which will easily extend battery life by a few days, so you got that going for you, which is nice.

You can also easily wake your smartwatch up by pressing the power button.


  1. Always keep an eye on your smartwatch’s battery status

Monitoring your smartwatch’s battery satus is always a good idea in my opinion. This allows you to determine which apps consume the most power, so that you can then decide if you need to close or even uninstall them.

Aside from that, constantly monitoring your smartwatch’s battery status will give you an idea of which battery saving measure you did worked best, and which did not do too well.



As you can see, there are multiple ways to improve the battery life of your Wear OS Smartwatch. There are some simple tweaks that can extend your smartwatch’s battery life for a few hours, and there are also more extreme methods that would most likely extend it for a few days.

In the end you will be the one who decides which battery saving method is right for you. Whichever method you use, I’m pretty sure that you will be able to maximize the battery life of your Wear OS Smartwatch if you follow these tips.
