Battery Indicator Incorrect on Series 5 Apple Watch

The Issue

I am having the following problem with my Series 5 Apple Watch, purchased four months ago:


1. After a full charge, the battery charge indicator remains stuck at 100% for approximately 4-9 hours.


2. The battery charge indicator then begins to decrease.


3. When the battery charge indicator reaches approximately 15-33%, the watch powers down suddenly, with no low battery warning (which should be given at 10%).


In summary, the battery charge indicator is essentially never correct. Below are two graphs showing this behavior:





My Attempts to Work with Apple on the Issue

I have worked with Apple thorugh multiple channels, and have been unable to obtain a solution to this problem.


My efforts include the following:


1. On January 22nd I consulted the Apple Store about this issue. The watch was sent to the repair facility and they were unable to duplicate the issue. It was sent back to me.


2. The issue continued to occur after I received my watch back from Apple. On February 4th, I chatted online with Advisor #1, who opened a case about the matter.


3. At Advisor #1's request, I collected screenshots documenting the occurrence of the issue. I also triggered a logging procedure on my watch during the times that the issue occurred.


4. On February 7th I had phone conversation with Advisor #2. During that conversation, we uploaded the logs and screenshots documenting the issue, for analysis by the engineering team. I also provided other additional information.


5. On February 21st, Advisor #2 got in touch and told me that we would need to collect further logs from the watch. She provided a link to a mobile configuration profile for my phone, which would allow collection of more detailed logs from my watch.


6. We scheduled a call on February 24th to upload the logs. Advisor #2 stood me up for that call. After trying with her over several days to reschedule, we finally spoke around March 4th. We attempted to upload the detailed logs that had been collected, but the upload appeared to keep hanging. She indicated that she would call me back after this to figure out a way to upload the logs.


7. I have not been able to get in touch with Advisor #2 since then, despite reaching out by email and voicemail.


8. On March 13th, I spoke with Apple Support by phone to try to sort this out, since it seemed by that point that Samantha had disappeared. Advisor #3 took down my number and said that she would have someone call me back. No one did.


9. On March 16th, I contacted Apple Support again by chat, to try to remedy this issue. Advisor #4 scheduled a call for me to speak with Advisor #5 today, March 17th, to resolve the issue.


10. Today, I spoke with Advisor #5 and was told that the only possible approach he can offer is to ship the watch back to the repair center to see if they can diagnose the problem (i.e, back to Step #1 in this long process). He would not make any effort to upload any of the logs that I collected in Step #5 of this process (which failed to upload in Step #6). Based on my past experience with Apple repair, my expectation is that they will be unable to replicate the issue and that the watch will be sent back to me. In that case, the only recourse he could offer was to visit the Apple store again once it opens back up (after Covid-19 passes).


My Questions

I am honestly at an absolute loss about how to proceed here. This support experience has been worse than abysmal and very different from past support experiences with Apple. I have three questions:


1. If anyone from Apple is reading this, could you please intervene to resolve this? Ideally, I'd like to try new hardware and see if that solves the problem, as I've spent around 5-10 hours of my time dealing with this issue. That said, I'm also happy to work with you on further troubleshooting of this hardware, but I need a responsive and competent support team member on the other side to make that happen, and I don't feel that I've had that so far.


2. Has anyone reading this forum experienced this problem? If so, have you been able to solve it? And, if you've solved it, how?


3. Does anyone have any advice for resolving this problem with Apple? They seem completely unconcerned, and it has been dragging on for almost two months.


Thank you very much for any help!

I bought a series 5 apple watch. It had the same problem. I took it to the Apple store and got a replacement, now the replacement is doing the same thing. I am wondering if I need another replacement. I am beginning to think that this a common problem with the series 5 and Apple has done nothing about it.

Both mine and my wife's Apple Watches started exhibiting this behavior within the past few days. Both are Apple Watch 4's. Hers the 40mm GPS Only and mine the 44mm GPS+Cellular Stainless.

Perhaps these are of importance? Maybe not:

I handle charging the watches every morning. Whenever possible I never charge any LiIon device to 100% in an effort to extend battery life. Every morning I charge both watches to 80% and the next morning they would normally show 30% to 40% so there was no problem going 24 hours with this charging regime.

So as a test I charged both devices for several hours which meant charging long after the charge level indicated 100%.

Now they exhibit the 100% charge level for a long time before the charge indicator begins to decrease. This will continue until the battery indicator shows 40% to 60% and then the devices just shut off. The only way to wake them is to put them on a charger. No button bushes will wake either watch. To me this means the watch battery is really flat out dead.

But is is?

What if in the mind of the Apple Watche the entire battery level is shifted by 40%? So if the battery is indicating a charge to 100% and immediately removed from the charger but really only at 60% or a difference of 40%? If you leave it on the charger beyond the 100% lever for an hour or so the battery continues to charge but the indicator can only go to 100%. The battery charging logic and indicator are out of sync. So now after extended charging the battery is truly 100% charged but the Watch thinks it's at 140% due so it's charging logic error. So now when the watch is removed from the charger the watch must deplete the physical battery buy 40% before the indicator starts decrementing. So now physical battery is at 60% the logical (software) indicator is at 100%. The watch continues to consume battery and when the physical battery is near 0% the indicator says 40% due to the above out of sync between the physical and logical (software) battery levels. When the battery indicator nears 40% it's really near 0% physical. The software won't trigger the low battery logic because it still thinks (erroneously) the battery is at 40% when it's almost at 0%.

The question to me is how to "resync" the physical and logical battery levels. Resets, repairing, hard restarts don't seem to do it at least for me. Does any of this make sense? I'm not excluding this being self inflicted by not charging to 100% every night but it took about 2 years for this to happen so I'm leaning towards a software issue perhaps due to a Apply Watch update.

I have found a very simple solution (somewhere on the web, just repeating it:) turn off the watch before putting it on the charger. You turn it off by longpressing the side button (not the crown) untill you see three slide bars. Slide the bar thatswitches off the watch.

Let it charge until it is fully charged again. (Wiggle or touch the watch a little and the screen lights up so you can see how much charging there is to be done). I have had no problems with the battery indicator since I turn it off before I charge it.

How do you know? Apple gave me a new watch (free, in the warranty period) when the first one started having these problems. They said nothing about hardware or software.

And what workaround exactly are you referring to? There are a couple of very complicated workarounds being suggested that do not work, and a simple one (turn the watch OFF before you place it on the charger and let it charge untill it is completely charged) that DOES work.

I did this before returning the second apple watch, which showed the same problems as the first. The problemems have disappeared thanks to this solution, so I did not have to return the second watch.

Apple Watch level 2 said it was software.

Perform the following procedure one time. To prevent reoccurrence until WatchOS7 is released Shutdown watch prior to charging from time to time. Simpler and less time consuming than returning the watch.


1) Charge watch for a minimum of 3 hrs (fully charge battery)

2) Remove watch from charger

3) Turn off watch (hold the side button (not crown) until the shutdown option appears and choose shutdown)

4) Wait a MINUMUM of 30 minutes. Even longer if practical.

5) Turn watch back on (press and hold the side button (not crown) until Apple symbol appears)

That's it.

Hello folks. I've been reading this thread. I bought my 5 in Feb. This same exact problem you are describing in this thread started with me AFTER I upgraded to Watch OS7. I have done most of the things described in this thread except resetting back to factory settings and starting over. Not sure I want to lose all my activity data. Apple needs to fix this. This is a HUGE problem for a lot of people. I was thinking of upgrading to the 6 series but now I'm second guessing that. This is frustrating.

I agree. What I have found and your mileage may vary is if once a week I shut the Apple Watch off for 30 minutes it minimizes the chances of shutting down prematurely, charge percentage staying at 100% for a long time etc. I suspect it doesn't need to be a full 30 minutes but I just set a calendar reminder to do it every "x" days so I don't forget. Simple enough. Try this experiment ... Note the level of charge on the watch, shut it down for 30 minutes and reboot, restart and after a few minutes note the level of charge. If the percentage is substantially lower than before shutting down then you are still experiencing this issue. The periodic reboot should at least keep the watch useable.
