Since I updated to iOS14 (iPhone 11 Pro Max) and WatchOS 7 (Watch Series 4), the day it was released, I've experienced the following issues:
- iPhone heats up continously
- iPhone battery doesn't even last 7-8 hours
- All Health data is completely inaccurate, e.g. if I've completed a 45 min run, which is accurate on my watch, it displays ~15 mins in the Health app, all calories, steps, exercise minutes, miles walked etc complete inaccurate throughout the entire day
- Fitness app - all historical maps and Outdoor runs/walks are missing, since 2015, including the weather data
- Not all workouts sync to the app (however, with Friends sharing, they can see the workout on my profile, but it's not synced in the app). Also, for workouts that do sync, any outdoor activity does not record the map route and it only displays a green pin on the location where the workout was started.
What have I done?
- On Saturday, I unpaired and then re-paired my Apple Watch - this did not fix the issue or make it worse, it was just the same.
What's the fix (may not fix it for everyone):
I've now fixed this, this is what I've done (there is no risk to this, providing that you have backed up your iPhone via iCloud or iTunes/Finder):
- Backup your phone - iCloud/iTunes/Finder - whatever you use
- Download the iOS14 IPSW file for your phone model (don't factory reset, as you want a clean install of iOS14): https://wccftech.com/how-to/how-to-clean-install-ios-14-and-ipados-14-final-version/
- Connect your iPhone to your PC or Mac
- Launch iTunes / Finder and click iPhone folder.
- Click the 'Restore iPhone' button while holding down the left Option key (Mac) or the left Shift key (Windows).
- Select the iOS 14 / iPadOS 14 IPSW file you downloaded
- Let this cleanly install iOS14 on your phone - it will take ~30-45 mins or so
- Restore from backup - iCloud or iTunes (iCloud takes 1-4 hours depending on how much data you have stored in the cloud)
- Re-pair your watch
- Go to sleep
- Wake up the next day
All my historical Outdoor run/hike/walk maps have reappeared. Any workouts since the iOS14 update does not appear and the 5-7 days Health data is all a mess for when I was experiencing the problem. Maps and routes are now being displayed in Fitness and the workouts are syncing. The Health data is all accurate and in sync. The phone is no longer heating up and the battery is back to normal - 93% since 6am!
I agree with people that we shouldn't have to do all this as Apple have completely messed this up - this is a bug and a serious issue with their Health and Fitness integration. I don't have the patience to wait for the fix, as it will take weeks (in my opinion) and I just want my Health and Fitness all back to normal. The biggest issue was the battery life and the phone heating up.
It's up to you all if you want to do this - do it in the evening, or whenever you've got time, there is no risk as long as you've backed up your phone.
