Smartwatches with the Best Battery Life

If you’re looking specifically for smartwatches with the best battery life, you’re going to run into some trouble.

One of the biggest problems with smartwatches is that the batteries within them don’t last long before you have to charge them. The average battery life for even the “smartest” watch is about 1 to 2 days.

Many of us already own smartphones that need to be charged daily, sometimes even more than that. Why would we adopt a smartwatch that needs to be charged just as much?

Either way, if you’re looking for a watch with a little more kick in the battery department, then you’ve come to the right place. We’re here to talk about smartwatches with the best battery life.

Weak Batteries

During your research phase when finding the best smartwatch battery life, you will find that many smartwatch batteries are weak, especially if you intend on continuously using the features the smartwatch offers.

Many companies claim that their smartwatch can last up to three weeks on a single charge, but they don’t always take into account other factors like heart rate monitoring, which can take even more battery power.

A hybrid smartwatch can preserve the maximum battery life a bit better than most smartwatches and has even been known to hold a charge for up to a year. However, many hybrid watches also don’t have digital screens and don’t provide you access to fitness tracking and activity tracking stats.

How to Improve Battery Life

In addition to reviewing our top recommendations for smartwatches with the best battery life, there are other ways you can improve your battery life.

Turn the Screen Off

You can set your display on most smartwatches to turn off when it is not in use. An always-on screen is understandably going to use more juice because it is, well, always on. Simply go into the settings, hit display, and tap on Always On screen to turn it off.

Different Watch Faces

You can also help preserve battery life by choosing a different watch face. Those that are animated or have other interactive abilities will take up more battery power than those that don’t.

Adjust the Screen Brightness

Next, adjust your screen brightness. The brighter the screen, the faster the battery will drain.

Turn Off Notifications

If you don’t want to receive notifications, it is best to turn them off and can go a long way in preserving your battery power. Go to the settings and tap on notifications. You can then block app notifications.

Turn Off Wi-Fi Syncing

If you own a smartwatch equipped with Wi-Fi, location tracking services, or NFC, you will want to limit connectivity to preserve battery life. Disabling your Wi-Fi and disconnecting from Bluetooth can help ensure your battery doesn’t overheat either.

Use Snooze

Some smartwatches come with a snooze feature. It won’t send notifications, won’t vibrate, and the screen won’t light up. This can save your battery while getting rid of some minor annoyances throughout the day.

Monitor Your Battery

Monitoring your battery is another great way to save your battery. Protect the battery from any damage and make sure the settings are appropriate for your current environment. Finding the right balance is key when you try to find solutions for extending your smartwatch battery’s life.

    Garmin Fenix 3 HR, up to 2 weeks… maybe you hate Garmin for some reason?

  3. tawster

    “The average battery life for even the “smartest” watch is about 1 to 2 days.”

    And then you continue with a whole article discussing smartwatches that last longer than 2 days. Just … odd. Heh.

    • Briley Kenney

      Right. Most smartwatches offer about 1 to 2 days of use on a single charge, like the Apple Watch, Moto 360 1st and 2nd Gen, Asus ZenWatch models, and many others.

      The watches on this list, however, are the exception and will last longer.

  4. Rick van Wijngaarden

    My Garmin Felix 3 goes for almost a month.

  5. FBomber

    I would consider these hybrids, not actual smart watches. The touch screen, functionality and personalization provided by a true smart watch is why the battery life is poor.

    • Briley Kenney

      Thanks for the comment, and good point! I definitely agree. 🙂

    Withings Steel HR has 25 days battery life.
