Improve Apple Watch battery life: 17 tips for saving power


Battery life on the Apple Watch has been fairly maligned over the years – and it’s now one of the few smartwatches with just one day of battery life. But if you’re frustrated by the regular need to charge, it’s possible to make the battery last a little longer.

Whether you’re wearing a shiny new Series 7, Series SE or an older model, like the Series 3 the quoted battery life of 18 hours is the same.

But there are ways to eke out a bit more. If you’re finding that your Apple Watch isn’t lasting long enough, here’s the best ways to improve battery life on the smartwatch.

Apple Watch battery life: FAQs

How long does Apple Watch battery last?

The most important thing to know about battery life is that it’s all relative; you could log a workout that drains the battery in a flash, or you could wear the watch all day without really checking it, and it’ll last longer.

With that said, Apple does provide a general recommendation that applies to the Series 6, Series SE, Series 5, Series 4 and Series 3: 18 hours of battery life after an overnight charge.

However, in our extensive testing, we’ve found both the Apple Watch Series 6 and SE to last around 36 hours between charges. That’s putting it on one morning, wearing to bed, and expecting it to die at some point the next afternoon. That’s without the extra strains of GPS usage or LTE.

What does that 18-hour estimation account for?

The official Apple estimate factors in 90 time checks, 90 notifications, 45 minutes of app use and a 60-minute workout with music playback from Apple Watch over Bluetooth.

In flatter terms, you could also zap the entire battery with a two-hour Bluetooth connected call, a one-hour LTE call or seven hours of streaming a playlist over LTE.

Does always-on screen make a difference to battery life?

Apple says the inclusion of this feature won’t affect the battery whether you turn it on or off. You can get longer than that 18 hours, but if you want to use the new sleep tracking support, you’ll be charging more regularly to use it based on our experience.

How long does the Apple Watch take to charge?

Apple estimates that it takes two hours for Apple Watch to charge, with 80% being reached after 90 minutes on the magnetic charging cable. This may vary if you’re using a third-party charger.

With the Series 6, it should take a quicker 90 minutes (1.5 hours) to get from 0-100%. For the Series SE, that slows down to 2 hours to get a full charge.

However, the Series 7 will get 80% charge in 45 minutes and be able to track a night’s sleep with just 8 minutes on the charger. However, to get these rapid charge times you need to use the new charging plate supplied with the Series 7, which is identifiable by the aluminum case.

How to turn on/off Power Reserve mode

There is an Apple Watch Power Saver mode, but it’s fairly nuclear, leaving your Apple Watch in a state where it only shows the current time. To turn it on head to Settings > Battery and toggle Power Saver on. To turn it off and go back to full power mode then just press the crown and side button together.

How to check battery life on Apple Watch

If you’re new to the Apple Watch, you’d be forgiven for not stumbling across the battery percentage during your initial play-around in the menus. Here’s all the ways you can view how much juice you have left:

  • Swipe up on the watch face to access the Control Center and see the battery percentage. To tap into the Apple Watch’s low power mode, touch the battery percentage and then drag the Power Reserve tab.
  • On some watch faces, you can add a battery complication.
  • On an iPhone, you can add a battery widget to show the battery percentage of a connected Apple Watch.
  • When your Apple Watch is charging in Nightstand Mode, simply hit the green charging icon to check the battery percentage.

17 tips to make Apple Watch battery life last longer

1. Turn down the color

There’s a reason the Apple Watch interface uses a black background: it’s more energy efficient for the device’s AMOLED display.

Some of the watch faces, though, like Mickey Mouse or the Activity Face, use plenty of vibrant colors and, subsequently, more battery life.

Because watchOS lets you create a handful of customized watch faces you can easily slide between, you should set up a simple black-and-gray watch face to switch over to when you’re in a battery bind.

There are a couple of minimalist faces, like Numerals and X-Large, that are perfect for this. Alternatively, if you’re really in a spot, you can turn on Grayscale mode by heading to General > Accessibility.

2. Turn off always-on display mode

This one obviously applies to Apple Watch Series 5/6/7 (not the SE), which support the ability to keep the display alive at all times. The problem however, that keeping that display is going to have some impact on staying power.

If you don’t absolutely need or want to use that always-on mode, go into the settings on your Watch, go to Display & Brightness and tap Always On to turn the feature on or off.

3. Disable Wake on Wrist Raise

On pre-Series 5 models, the Apple Watch uses its gyroscope and accelerometer to instantly turn on the display for easy viewing whenever you raise your wrist.

Unfortunately, this means that any time you raise your wrist the display will activate. Like when you’re watching a movie, or raising your hand, or stretching. And each time it does, battery life inevitably takes a tiny punch.

You can put an end to this by heading to Settings > General > Wake Screen and toggling off ‘Wake Screen on Wrist Raise’. You’ll then need to tap the screen or a button each time you want to wake the display.

As we mentioned up top, Apple says this doesn’t affect battery life on the Series 5, so read on for more tips if you have the latest model.

4. Reduce motion

There are plenty of fancy graphical tricks in watchOS that are designed to make transitions as seamless as possible, but they also draw a little more power from the processor, which in turn draws a little more life out of that battery.

If you don’t need the neat melding animation to the app home screen or transparency effects when you swipe down on the notification pane, you can turn them both off in the Accessibility menu in the Watch app.

5. Turn off the heart rate monitor

If you’re not interested in the Apple Watch tracking your heart rate every couple of minutes, you can disable the heart rate monitor.

While the heart rate monitor constantly checking your pulse improves the accuracy of calorie estimations, it does take up a significant chunk of battery power to do so.

You can turn it off by heading to the Watch app on your iPhone and going to Privacy > Motion & Fitness. While you’re there, you can also turn off fitness tracking if the fitness elements of the watch aren’t vital to you.

6. Turn off blood oxygen monitoring

Pulse ox technology is one of the heaviest drains on battery life, and you can turn it off just like heart rate monitoring.

Head to Privacy > Motion & Fitness and toggle off Blood Oxygen Measurements. You can still keep the heart rate monitor on for standard bpm tracking, if you please.

7. Turn off environmental sound tracking

The Privacy menu is a hidden trove of marginal gains, and there’s one more thing you can turn off here.

The Apple Watch will monitor your background sound levels and warn you if they’re loud enough to damage your hearing. If you don’t want that, you can dispense with this extra piece of continual processing power.

8. Customize iPhone mirroring

Mirroring core iPhone apps like Mail, Messages and Calendar can be extremely helpful, but they can also be redundant.

Do you really need both your Watch and iPhone ping for an email? Even worse, it sucks battery life.

You can reduce these issues by customizing how the Watch mirrors those core iPhone apps in the My Watch pane of the Watch app. You can turn off Phone alerts, disable Message alerts and choose which of your mailboxes can send you Watch alerts.

9. Workout Power Saving Mode

If you want to save battery life while working out, Apple has a mode for you.

If you turn on Workout Power Saving Mode in the General section of the Watch app, the phone will turn off the heart rate monitor for walking and running exercises.

Your calorie burn calculations may be less accurate, but you’ll save some juice.

10. Get rid of Activity Reminders

The Activity app is always on your case. If you’ve been sitting for 50 minutes in an hour it’ll remind you to stand. It’ll give you progress updates every four hours. It’ll notify you when you get an achievement.

And then, every week, it’ll send you a summary of what you did and recommend new goals for the next week.

It’s helpful stuff, but all those notifications can ding battery life. You can turn them off in the Activity menu of the companion app.

11. Adjust the haptic vibrations

Sure, getting that gentle buzz when you receive a text, prompt or call is a great way to keep up to date in a discreet way, but limiting this can also have a slight effect on your battery.

If you head to to Settings and go into Sounds & Haptics, simply turn off Prominent Haptics off. Or, alternatively, you can also fiddle with the haptic strength by sliding the control.

12. Turn off Siri

Every time your display is on, your Apple Watch is searching for those two magical words, “Hey Siri,” so that Apple’s personal assistant can set your next appointment or play your favorite song.

It’s a good way to accomplish things hands free, but it’s also a good way to drain your battery. You can turn it off by going to the Siri menu of the General section in the Settings app on your Apple Watch.

13. Turn on Do Not Disturb

You’re in a big meeting and want to neutralise your Apple Watch pings, but you also want them to return after the meeting without having to faff about in big menus. Sounds like you need a healthy dose of Do Not Disturb, friend.

To access Do Not Disturb, simply swipe down from the watch face and bring up the Control Center. Hit the moon icon, as shown above, and your Watch will avoid lighting up, buzzing or making noise for a temporary period.

To adjust just how long this period is, Force Touch the icon. Handily, like on the iPhone, Do Not Disturb can be set to end when you leave your current location, when an event in your Calendar ends or simply for a select period of time.

14. Slim down background refreshes

All of those apps on your Apple Watch are constantly refreshing in the background, pulling in new information so that when you open up the app, you have the latest news or sports score right there with minimal waiting. That convenience comes at a price: battery life.

There’s a Background App Refresh menu in the General section of the Watch app. That’s where you’ll be able to either turn off all background refreshes or toggle them on or off for individual apps.

So you can prioritize refreshes in apps you rely on while turning them off on non-essential apps you rarely use, saving battery life.

15. Turn off the sound

The Apple Watch can ring whenever you receive a notification, which can be helpful if you’re not into haptic feedback, but isn’t so helpful with battery life.

You can turn off the sound pretty quickly by swiping up, tapping the bell icon and being done with the beeps and bops.

16. Use Theater Mode

Theater Mode is great for meetings and dark places – like a movie theater, duh – where you expect notifications, but you don’t want your screen accidentally turning on and distracting everyone else.

Bonus benefit: Because it doesn’t turn on the screen, it’s not using as much battery power, which means you’ve got a little more juice to get you through the day.

17. Turn on Power Reserve mode

If you’ve done everything you can, and you’re still in danger of running out of juice, there’s always Power Reserve mode to tap into. You can turn this on by pressing and holding the power button and then choosing Power Reserve.

This’ll shut down all features except the time, meaning you won’t be stuck with a dead screen on your wrist.
