Charge your Apple Watch’s battery

If your battery is low on charge, getting accurate fitness metrics is often impacted. So, before you start your day, make sure your watch battery is at 100%.

Alternatively, try discharging your Apple Watch and then charge it overnight (or for 12+ hours continuously)

Some readers discovered that if they let their Apple watch battery completely discharge and only then charged it fully (usually overnight) the next day, their Apple Watch recorded steps and flights of stairs accurately.

Clean your Apple Watch

Most Apple Watches (Series 3 and above) include a barometric sensor that helps calculate elevation and determine approximate altitude.

That barometric sensor records any change in your elevation.

Sometimes, it counts things as stairs and flights climbed, even if you actually did not climb any but changed your elevation while moving during activity.

For example, it won’t count elevation changes in an elevator (because you aren’t engaged in active motion.) But it will count elevation changes when going up and down a hill. And if a weather event like a hurricane passes through your town, you’ll likely see some interesting results in your flights of stairs climbed due to the sudden atmospheric and barometric pressure changes!

What’s important here is that your Apple Watch’s barometric sensor uses the watch’s air and speaker vents as a barometric vent to equalize the watch’s internal pressure.

Sometimes, lint, dirt, and other debris get trapped in these vents, preventing the barometric sensor from operating correctly.

So a good, old-fashioned cleaning often saves the day!

How to clean your Apple Watch, so it counts stairs and steps accurately

  • Remove any bands that could be damaged by water (like fabric and leather bands)
  • Swipe up Control Center and tap the Water Lock button
    • You want the water lock active for the entire cleaning process water lock feature on Apple Watch
  • Use a dry microfiber or lint-free cloth and wipe your Apple Watch–make sure you cover all sides, the buttons, digital crown, and focus on those vents to ensure nothing is trapped in there
  • Lightly dampen the cloth with fresh water, use a 70% isopropyl alcohol wipe, an electronics wipe, or Clorox disinfecting wipe, and clean your watch again
    • Alternatively, hold your Apple Watch under lightly running, warm freshwater for 10 to 15 seconds
    • Never use bleach, soaps, detergents, or other cleaning products to clean your watch
  • After cleaning, take another dry cloth and wipe the watch to pick up any remaining moisture
  • Turn off Water Lock and eject water by turning the Digital Crown on the side of your Apple Watch until the display says Unlocked eject any water or liquid from your apple watch by turning the watch's digital crown when water lock is on
    • You hear a set of tones as your watch expels any remaining water
  • Let your watch air dry in a shaded location or near a fan. Make sure the watch (and band, if applicable) is 100% dry before placing it back on

Reset your Fitness Calibration data

If nothing’s worked thus far, try resetting your watch’s fitness calibration data. We keep this option as our last because this action deletes all of your calibration data and history. It’s like starting fresh. 

But if your watch isn’t accurately capturing your activity data, then it is our recommendation to reset your watch’s calibration.

  1. On your paired iPhone, open the Watch app
  2. Select Privacy
  3. Scroll down and tap Reset Fitness Calibration Data and confirm.reset fitness calibration data on Apple Watch
  4. If possible, immediately go for a walk, hike, or run to recalibrate your watch.

Unpair and re-pair your Apple Watch

If all else fails, try unpairing and re-pairing your Apple Watch from your iPhone. When you unpair, Apple automatically creates a backup for you to restore to when you re-pair.

  1. Place your Apple Watch on its charger and put it next to your iPhone.
  2. Open the Watch app on your iPhone.
  3. Go to the My Watch tab and tap All Watches.
  4. Tap the “i” info button next to the watch that you want to unpair. apple watch info i button
  5. Tap Unpair Apple Watch. apple watch unpair from iPhone
  6. Follow the instructions on-screen to unpair. 
  7. Once unpaired, pair your watch again, follow the screen’s instructions, and when asked, choose to Restore from Backup. Apple Watch set up as new or restore from backup

If you continue to have issues, run through these steps again, but choose to Set Up as New Apple Watch

For more detailed instructions on unpairing your Apple Watch, see this article: Unpair Apple Watch with or without your iPhone or Watch

When you set it up as new, it sets it up as if it just came from the factory. So none of the apps, personalizations, etc. carry over. You will need to set up and install those again.

Wrap up

If your Apple watch counts too many steps or flight climbed, we hope one of these tips worked for you.

And if not, let us know. Got a better tip for this problem? Let us know that too and pay it forward.

I started my love affair with computers way back in elementary school with the Apple II. Since then, I've worked with technology in my career as a media educator and videomaker. I have an MFA in media making from Temple University, where I also taught undergrads as an adjunct faculty member. So I know a thing or two about teaching others and creating how-to guides! After a cancer diagnosis, I turned to mobile technology like my Apple Watch to help me monitor my health throughout my chemotherapy treatment and later, to regain my wellness once in remission. I love sharing how to understand and use mobile tech, like smartwatches and phones, as a tool for empowerment to live our best and healthiest lives!

  1. Contacted apple support after trying all of the above with no success. They want 6 weeks and $349 to fix the problem in a watch tha5 is less than 18 months old. Planned obsolescence anyone?

  2. My series 3 watch never could count steps. Watch or app or health data issue? Not worth worrying about. That’s what apple counts on. Same thing with ipad air that bricked after one year.

  3. My series 1 Apple Watch lasted 3 years before it would not take updates.

    When I passed it on it still had 90% battery health. My Series 5, which I have paired down to a minimum of apps and no cellular is down to 86 % after 16 months.

    My flights climbed is wonky as can be. I have to recharge the watch by 6:00 each evening and I manor doing anything different than I did when I first got it and I still had 30%-40% by the end of the day.

    I just unpaired and repaired. Hope this works
