The most common Apple Watch problems (and how to fix them)

Before we get into the list of more specific Apple Watch problems and their possible solutions, there are a couple of things you should try right off the bat. Firstly, restart your Apple Watch. It may sound like a cliché, but many odd behaviors are indeed solved by a simple reboot. Here’s how to do that.

Step 1: Ensure your Apple Watch is not on its charger, and hold down the side button until a screen appears with the Medical ID and Emergency SOS sliders.

Step 2: If your device is using watchOS 9 or newer, you should see a power button in the top-right corner. Select this, and a Power Off slider should appear.

If your device is using watchOS 8 or older, you’ll see the Power Off slider on the first screen above the Medical ID slider.

Step 3: Select the white button to the left of Power Off and drag it to the right. Your Apple Watch should power off.

Step 4: Wait at least 10 seconds to ensure your watch has fully shut down, and then press and hold the side button again until the Apple logo appears. Then release it and wait for your Apple Watch to finish starting back up.

If your Apple Watch fails to start up or won’t turn on, you can force-restart it by holding the side and Digital Crown buttons down together for 10 seconds until the Apple logo appears. This also works to reboot your watch in the event that an app is hung or it’s otherwise become unresponsive.

The second common step is to make sure that your Apple Watch is running the latest official release of watchOS. Apple routinely fixes problems in even the most seemingly minor updates, so it’s possible that whatever problem you’re running into has already been fixed, and you just need to apply the update to take advantage of that.

While it’s true that your Apple Watch should install updates automatically (unless you’ve explicitly turned this setting off), those automatic updates can sometimes take days or even weeks to appear. Checking manually is the surefire way to get the latest updates as soon as possible. You can do this from your Apple Watch or your iPhone. Here’s how.

Step 1: To check for watchOS updates from your Apple Watch, open the Settings app and select General > Software Update.

To check for watchOS updates from your iPhone, open the Watch app and select General > Software Update.

Step 2: Your device will reach out to Apple’s servers to see if any updates are pending. If one is found, you can install it by selecting Download & Install. Otherwise, you’ll be advised that your Apple Watch is up to date.

Step 3: If you’re checking for updates from the Watch app on your iPhone, you’ll also be shown the version of watchOS that’s installed on your wearable. If you’re doing this from your Apple Watch, you’ll merely be told that your device is up to date. If you’re curious, you can find out what version you’re using by selecting General > About from the watch’s Settings app.

Note that only the Apple Watch Series 4 and newer can be updated to watchOS 9. If you’re still using an Apple Watch Series 3, you won’t be able to move beyond the latest release of watchOS 8. That’s 8.7.1 as of this writing — and will probably continue to be the latest unless Apple discovers a critical security flaw in that version and needs to release a patch for it.

If you run into problems updating your Apple Watch to the latest version of watchOS, try restarting both your Apple Watch and iPhone and trying to run the update again. If the Apple Watch still fails to update, it’s likely the result of a botched download attempt. Here’s how to clear that out so you can download a fresh version of the watchOS updater.

Step 1: On your iPhone, open the Watch app.

Step 2: Select General from the My Watch tab.

Step 3: Scroll down and select Storage. After a few seconds, you should see a list of what’s taking up space on your Apple Watch.

Step 4: Look for the entry for the watchOS update, select it, and choose Delete to remove it from your Apple Watch storage.

Also, remember that while you can download a watchOS update at any time as long as your iPhone is in range of your Apple Watch and connected to Wi-Fi, the update won’t actually install until your Apple Watch is charged to at least 50% and sitting on its charger.

If your Apple Watch isn’t charging when you connect it to its magnetic charger, there are a few things you can try before taking it in for service.

Step 1: Try charging with the official Apple Magnetic Charging cable that came with your Apple Watch and confirm that it’s connected properly to the USB power adapter and outlet.

Step 2: Clean the back of your Apple Watch and the top of the magnetic charger to ensure there’s nothing interfering with the magnetic contact. Also, make sure you’ve removed the plastic wrap from both sides of the charging disc.

Step 3: If your Apple Watch still isn’t charging, try force-restarting it by holding down the side button and the Digital Crown for 10 seconds until the Apple logo appears.

Note that if your Apple Watch battery has dropped low enough that it won’t even light up in Power Reserve mode, you may have to wait a few minutes before the green lightning bolt appears on the watch face to confirm it’s charging.

You may find sometimes find your Apple Watch repeatedly asking you to enter its passcode. It’s not entirely clear what causes this issue, but ensuring the following settings are enabled and changing your passcode can help resolve it.

Step 1: Open the Watch app on your iPhone and select Passcode from the My Watch tab.

Step 2: Ensure that Wrist Detection and Unlock with iPhone are both enabled.

Step 3: Select Change Passcode and follow the instructions to set a new passcode on your Apple Watch.

Step 4: Make sure that your Apple Watch fits snugly on your wrist, with the back in contact with your skin at all times — not worn over clothing. The Wrist Detection feature relies on skin contact with to keep your Apple Watch unlocked, so if your Apple Watch can’t detect your wrist, it will require a passcode every time you want to use it, just like when you’re not wearing it.

If your Apple Watch isn’t lighting up properly when raising your wrist — either staying blank or showing the dimmed always-on display — here are a few things you can check.

Step 1: Ensure that the Wake on Wrist Raise setting is enabled. You can find this under Display & Brightness in either the iPhone Watch app or the Apple Watch Settings app. If this is already on, try toggling it off and back on again to reset it.

Step 2: Ensure your Apple Watch isn’t in Theater Mode. As the name suggests, this setting is designed to prevent your Apple Watch from inadvertently lighting up in a darkened theatre, which could distract those around you.

When Theater Mode is enabled, you should see a small orange icon at the top of your screen that looks like a pair of masks. To disable Theater Mode, tap on your watch screen or turn the Digital Crown to wake it up, swipe up from the bottom to bring up the Control Center, and then look for the orange Theater Mode icon and select it to switch it off.

If you’re having problems connecting your Apple Watch to a Bluetooth device such as headphones or a fitness accessory, or if your Apple Watch frequently disconnects from your iPhone, here are a few things you can try to get it working again.

Step 1: Firstly, proximity matters for Bluetooth, and some devices may be more sensitive to that than others. Some people have reported better performance simply by switching the device they’re using to the same side of their body as the Apple Watch. You could also try switching your Apple Watch to the other wrist. Such a small change in distance shouldn’t make a difference, but some devices can be finicky, so it’s worth a try.

Step 2: Toggle Bluetooth off and back on again on your Apple Watch. This can be found in the Bluetooth section in the Settings app.

Step 3: If the issue is with Bluetooth headphones and music streaming, syncing your playlist onto your Apple Watch and turning off Bluetooth on your iPhone might help. This avoids extra Bluetooth interference and may allow your music to play seamlessly without annoying disconnections.

First, try toggling the Bluetooth off using the icon in the iPhone’s Control Center, accessed by swiping down from the top-right corner of your iPhone screen. This disables Bluetooth connections from your iPhone to devices like headphones but leaves Bluetooth enabled for communicating with your Apple Watch, so you’ll still be able to connect to the internet and receive notifications from your iPhone.

If that doesn’t help, try switching the Bluetooth radio off entirely on your iPhone by going to the Settings app, selecting Bluetooth, and toggling it off. This will disconnect your Apple Watch from your iPhone, but you can still listen to the music stored on your watch and any workout data will be synced to your iPhone once you re-enable Bluetooth at the end of your run.

Sometimes your Apple Watch won’t properly track your workouts. This can take several forms, such as inaccurate or missing workout metrics, not having your routes tracked, or workout data from your Apple Watch failing to appear on your iPhone.

Step 1: If your workout data is accurate on your Apple Watch but isn’t appearing properly on your iPhone, ensure that Bluetooth is enabled under Settings > Bluetooth on both the iPhone and Apple Watch, and try restarting both devices to see if things sync up.

Step 2: If you’re getting inaccurate readings for things like calories burned or heart rate, make sure your Apple Watch isn’t too loose on your wrist. Adjusting the band may help the watch better track your activity.

You can often see this problem by the heart rate indicator turning a faded grey during a workout, showing that your Apple Watch isn’t picking up your heart rate properly from your wrist. It’s not abnormal for this to happen occasionally during some workouts, but if it’s happening more frequently, it could indicate a problem with the fit of your Apple Watch, a bug in the watchOS software, or an issue with the physical heart rate sensor.

Step 3: If workout data doesn’t seem accurate, your watch may need recalibrating. You can start this process by opening the Watch app on your iPhone, selecting Privacy > Reset Calibration Data, and following the calibration instructions.

Step 4: Ensure your personal information, such as height and weight, are up to date. The Apple Watch uses this data to calculate things like calories burned, so while it won’t stop your Apple Watch from tracking your workouts, the data you get may not be as accurate if this information is out of date.

You can check this by opening the Watch app on your iPhone and selecting Health > Health Details. If anything needs to be changed, select the Edit button in the top-right corner and make any necessary updates. This includes adding any medications you’re taking that could affect your heart rate.

Step 5: If your walking or running routes aren’t being tracked properly, ensure that location services are enabled under Privacy & Security > Location Services in your iPhone Settings app. Both Apple Watch Faces and Apple Watch Workout should be set to While Using with Precise Location toggled on.

Also, be sure you’re using the Outdoor version of walking or running workouts, as the GPS on your Apple Watch doesn’t kick in for indoor workouts.

Following the release of the Apple Watch Series 3, the first LTE-capable model of the wearable, we saw more than a few reports of problems connecting to the cellular network. Apple has long since fixed this bug, which had to do with the hand-off between Bluetooth, Wi-Fi, and LTE.

If you do run into this problem where your cellular Apple Watch refuses to connect to an LTE network, it’s most likely either a glitch with how your plan was provisioned on your Apple Watch or an issue on your carrier’s end.

Step 1: Try setting up your cellular plan again through the Watch app on your iPhone. Choose Cellular, select the i button to the right of your carrier name, and then choose Remove [carrier] Plan from the pop-up that appears at the bottom of your screen.

Once the plan has been removed, you can add it again by selecting Add a New Plan and following the instructions to reactivate it with your carrier.

Step 2: If that doesn’t resolve the issue, reach out to your mobile provider. We’ve seen reports, particularly from AT&T customers, that their LTE plan had to be reinitialized on the carrier’s end for things to start working properly again.

For some folks, the area of skin that comes into direct contact with their Apple Watch’s sensors can become itchy and feel uncomfortable, especially after wearing it for an extended period of time. Some people have this problem with watches in general, but even those who have never encountered this with other watches may find the sensor points on the Apple Watch to be specifically irritating.

Unfortunately, this is usually a skin sensitivity issue, so there isn’t really a technical solution for it. However, there are a few ways to lessen its impact:

Step 1: Loosen the strap on your Apple Watch. Sometimes the issue can be caused by sweat becoming trapped between the skin and sensors, effectively lowering your skin’s ability to breathe. Loosen your strap a little, and the extra room will allow your skin to breathe a little better. This shouldn’t affect your Apple Watch’s sensors too much either as long as they remain in contact with the skin; they don’t need to be tight against your wrist, just touching it.

A few years ago, a number of Apple Watch SE owners shared reports that their wearables were getting extremely hot on their wrists. This was typically followed by physical damage to the watch’s screen.

We haven’t heard any reports of this recently. Still, if you run into a situation where your watch is heating up to the point of being uncomfortable, it’s best to take it off and let the battery run down — don’t put it on the charger, as that’s likely to exacerbate the problem. This is almost certain to be a hardware fault, so it’s best to take it to an Apple Store or Apple Authorized Service Provider before you attempt to wear it again.

Apple promises up to 18 hours of battery life for the Apple Watch, and while your mileage will vary on that one, a relatively new Apple Watch should still be able to get you through the day before you need to refuel.

Keep in mind that the Lithium-ion batteries used in most modern electronics have a limited number of charge cycles. For the Apple Watch, that’s 500 full discharges and recharges. Once that number is reached, your battery capacity will slowly begin to drop. For most Apple Watch users, this works out to about two years of normal use before it becomes noticeable. So, if you’re still wearing an Apple Watch that’s more than two to three years old and your battery is no longer cutting it, you’ll likely need to either get the battery replaced or upgrade to a newer model.

Whether it’s new or old, here are a few things you can try to eke some longer battery life out of your Apple Watch:

Step 1: If you have a cellular Apple Watch model, be aware that using LTE drains the battery significantly faster. Using the Apple Watch on Wi-Fi is considerably better, but it will get the best battery life when you keep your iPhone nearby. Your iPhone has a much bigger battery, so your Apple Watch prefers to let it do the heavy lifting of handling power-hungry data communications.

If you regularly go out without your iPhone, disabling your cellular connection can make a big difference in battery life. You can easily toggle cellular off and on through the Control Center, accessed by swiping up from the bottom of the screen when viewing your watch face. Alternatively, take your iPhone with you whenever you can.

Step 2: If you have an Apple Watch Series 5 or later with an always-on display, you may be able to save a bit of power by toggling this off under Settings > Display & Brightness. The always-on display is designed to consume very little power, but if your Apple Watch is older and your battery is getting weak, every little bit helps.

Step 3: While you’re in the Display & Brightness settings, try turning down the brightness of your display. Again, every bit of power conservation can help here.

Step 4: Similarly, toggling off Wake on Wrist Raise in the Display & Brightness settings will keep your display from turning on as frequently — especially if you move your wrist more often. When this setting is off, you’ll need to tap on the screen or move the Digital Crown to light it up.

Step 5: Opening the Watch app on your iPhone and selecting Notifications will let you review anything that might be needlessly coming to your wrist. Fewer notifications mean fewer haptics, sounds, and activation of the display. Plus, you’ll get more peace of mind by filtering out the things that aren’t really urgent enough to appear on your watch.

While it’s a more drastic step, if all else fails, you can easily restore your Apple Watch back to factory settings and then re-pair it with your iPhone as if it were a new device. When you do this, you’ll have the option of restoring from your last backup or starting fresh.

Step 1: Open the Watch app on your iPhone.

Step 2: Select All Watches in the top-left corner of the “My Watch” screen.

Step 3: Select the i button to the right of the watch you would like to unpair.

Step 4: Select Unpair Apple Watch at the bottom of the screen, and then select Unpair [your Apple Watch name] to confirm.

Step 5: If you’re using a cellular Apple Watch, you’ll be asked whether you want to keep your cellular plan or remove it. In most cases, you should select Keep Cellular Plan as you’ll be setting this Apple Watch up again.
