Recently the Health app is not calculating my walking distance accurately (it's off by .5 miles on a 3.5-mile walk; saying I walked 3 miles). It used to be accurate. Why is this happening and how can I fix it?
iPhone 8 Plus, iOS 14
Hi bikemarlene,
Understood, thanks. As this information is being pulled directly from your iPhone, we'd recommend checking the settings from the articles below to improve GPS accuracy and ensure location services is enabled.
About privacy and Location Services in iOS and iPadOS
Control the location information you share on iPhone
Additionally, you may want to check your device during this walk to see if you're losing cellular service at any point as this wouldn't allow for an accurate recording.
We recommend also taking a look at the section "Prioritize data sources" from the article here to ensure the sources that the Health app uses first are set to your personal preference. Manage Health data on your iPhone
You can also test a normal restart of your device, and ensure your iOS is fully up to date.
Update your iPhone, iPad, or iPod touch
Cheers!

Thanks but it’s not an Apple Watch, it’s my iPhone. Why would it have been accurate 6 months ago and not now?
Health app distance calc is way off
