Battery Indicator stuck at 100% All day

My battery indicator stays at 100% and then will die without warning. Has anyone had this issue? It started doing this within 2 weeks of receiving the watch, the update (6.1) did fix it temporarily and then a couple of days ago, it started again.

Apple Watch Series 5, watchOS 6

I had the same issue and had tried all of the usual suggested solutions. I then found a tip that I had not seen before and it worked for me (for a week now at least). I'll share it in hopes that it works for others as well.

  1. Turn the power off on the iPhone and leave off for at least 20 minutes.
  2. Turn the power off on the Watch and leave off for at least 20 minutes. I left both off for 30 minutes.
  3. Turn the iPhone on.
  4. Turn the Watch on.

Lo and behold, it worked! The battery went to 65% and ticked down in normal increments without shutting off. I have fully recharged every day since and it the battery continues to work normally. I can't explain why that worked, but I hope it works for others having the same problem.

My phone is fine, other than a few minor beta bugs. Months ago, a former Senior Advisor who I knew theorized that it was the phone that was at fault, because it was syncing the software to the watch. He suggested a hard reset after I received the new one, and said I should restore everything from the iCloud. While the issue reappeared, it confirmed the phone issue since it never appeared for the technicians.

TL;DR: try manually putting your watch into power reserve mode and then turning it back on to recalibrate the battery meter.


Like others here, this issue cropped up on my Series 4 when sleep tracking shifted my overnight charging routine to morning and evening top-ups. I have worn this watch since launch day in 2018 and never had the problem; figured it was beta-related until I read this thread. Same symptoms: battery stuck in the 90-100% range, but would die in the middle of the day, especially after a workout. Back on the charger, it’d immediately show 100% and not charge further. Hard resets and leaving the watch shut off were unreliable fixes.


But I just found something that worked. I manually put my "100%" watch into power reserve mode, then turned it back on. The battery meter immediately showed the truth: 10% remaining. Now it’s charging normally again. Maybe this will work for y’all too.


Good luck!

Try a forced reset;

To force reset your Apple Watch, press and hold both the side button and Digital Crown for at least 10 seconds, then release both buttons when you see the Apple logo.
