Yet another dying battery thread with Series 4 and update 6.2.1

  • The Problem
    • My watch has been running out of battery very very quickly.  It always seems to get to about 41% then just shut off some time later.  It acts like a dead battery.  But when I put it on the charger, it starts up like it has no battery, then within a minute it says it has 41% charge again.   I think it is this issue:  https://discussions.apple.com/thread/251266826
    • What started as an issue of the battery draining to 41% has turned into one of being stuck on 100%, after numerous resets. https://discussions.apple.com/thread/250840427
  • What I've tried:
    • I've tried pairing and unpairing repeatedly.  
      • Doesn't work.  
    • When re-pairing, I've tried restoring and setting up as a new phone.  
    • hard reset (hold two side buttons) reset my watch at least 10 times
    • turned off and on my phone repeatedly,
    • unpaired and re-paired the watch several times
    • I've tried re-pairing with restored settings and also re-paired as a new watch


  • Details
    • First, I un-paired and then re-paired the watch with phone.  
      • I chose "restore from backup"
    • I also just did 3 hard resets in a row on the watch per https://discussions.apple.com/thread/250840427?answerId=251597515022#251597515022
      • Later the author suggests repeating the reset multiple times, along with pairing/unpairing.  This is nasty.  
    • Another thing I'm trying:  turning the watch off for an hour while stuck at 100%.  Worked for someone. 
    • I have restarted watch and phone many times....


Apple Watch Series 4, watchOS 6

  • This seemed to fix it: 
    • Charge the watch for long enough that you know it's truly at 100% despite it's incorrect battery measurement/readout.
    • Power off watch for 15-30 mins (the amount of time is TBD, but I did 30 mins)
    • Turn watch on.



  • Details:  
    • OK now it's 10:40 AM and I just removed the watch from the charger at 100% full charge.  Normally this would hold easily through the next morning. 
    • 13:41 still at 100% charge, after walking 5000 steps, suspicious.  One of the threads is exactly this, stuck at 100% and then running suddenly out after only a few hours and no warning.  We shall see
    • At 16:05 it still shows 100% charge, so  I unpaired the watch again as there is no way I didn't even drop 1% charge in all this time.  I am restoring from the 16:04 backup
    • The watch is NOT charging, I'm doing this all on my wrist.  Syncing now...
    • 17:23 and still 100% LOLz death is upon us 
    • Another reset, no love
    • OK I turned it off for 30:30 min.  Restarting...  so slow
    • 18:05 Hey!  97%, changed to 96% while I was watching... uh oh, now to 95%
    • Now we have the power draining super fast.  How crazy
    • 18:08  It's dropped from 97% to 78% in 3 minutes
    • 18:10 69% 
    • 18:13 63% slowing down?  Maybe it's stabilizing towards its true value now for some reason. 
    • 18:15 63% still.  Huh. 
    • 18:41 62%  is it fixed?  this seems exactly normal
    • I'm rebooting at 18:43 to sync my VoiceMemos.  Sure does seem to take a lot longer to reboot my watch lately.  
    • 18:49 59% after futzing a little with Voice Memos... -- maybe I'm back to cancer
    • 18:51 58%
    • 20:02 55% holding firm again, huh
    • 20:59 53%
    • 22:50 48%  off to bed now...  is it fixed? 
    • 07:03 31% hurrah!  I think it's fixed.  I'm recharging now

Reported. Their site to report sucks. Has a character limit on text box so I couldn’t explain in full. Also outdated in terms of selecting watchOS version (doesn’t have latest). Fingers crossed they will find the big and fix the issue- but hopes are low based on reporting mechanism. They’d be better off reading these forums.

Actually ended up getting a brand new S5, and restored from backup. After a watchOS update- same problem happened again. I believe the issue is triggered on some watches (educated guess: possibly depending on apps or settings) by the update, b/c it doesn’t happen to everyone.


Charge up to 100%, turn off 30 mins, turn on- worked again. Has been stable for almost a month since.


did you update recently?
