I think there are two possible causes,
1. If this is the same tone you get when first connecting the charger, the charger may be disconnecting then reconnecting (at least logically if not physically), so it would be worth testing with a different USB power adapter and magnetic cable, according to what you have available. I know you have the adapter which charges your iPhone, so that would be perfect for testing.
2. Something actually wrong in the watch, either software or hardware. Software is a prime suspect because it started with the update. You could try unpairing and re-pair to your phone again to force reinstalling the Watch software. If that still doesn't work the last resort is Contact Apple Support and arrange to get it checked by Apple. Don't just skip to calling Apple Support, make sure you already tried the earlier steps because they will want to try these first.
Don't forget you can charge your watch at any time, you don't need to wait until overnight for testing the fixes!
I am using the original cable that came with my Apple Watch I was using a Spigen charging block at 1a I switched to the Apple charger that came with the Watch and so far no issues
Look closely at the charger. Where it connects to the iWatch I found some of the protective clear packing I neglected to remove when setting it up. Removed it, no beeps
Oh that's strange. Apple Support finally came back with a response from their engineering team. Apparently All Series 3 Aluminium's made after September 2018 exhibit this issue as it's an incompatibility between the old plastic chargers and the new ones. And the only fix is a stainless steel charger or an Apple Watch Dock.
It it may help others if you can post the exact response as a pasted email, or a scanned document, or a link to the original statement - or whatever else works. Everyone needs to see and be able to refer to this confession from Apple when seeking support.
I have an Alu cellular S4 44mm... same issue. Very strange changing behaviour. Charge chime every 15 mins. Sometimes starts discharging a little after settling at 100% for some time. I have to admit my situation is complicated by the use of third party chargers. So, I'm not sure if it's the third party charger not being S4 compatible or if this is a software issue.
I gave away the original charger, that came with, when I sold my previous watch and its cable failed (after my cat chewed it) right before I was about to ship it to the buyer. I needed a quick solution and sacrificed the S4 cable.
I then bought a third party wireless charging stand for both iPhone and Watch which came with its own QC 3.0 PSU. It was with this that I noticed the charge chime happening again and again. I then went on to buy another third party but allegedly "Made for Apple Watch" charging cable. The behaviour persisted and this was using the Apple-supplied S4 PSU (which seems identical to all previous models).
I'm really worried about the impact to the battery life here whether it's a software issue or incompatible third party chargers.
The next watchOS release isn't too far off. If it persists beyond that, then I'll need to bite the bullet and buy a charging cable direct from Apple. That way I can eliminate the third parties from being at fault here.
I'm seeing some of you have been experiencing this with Apple charging cables. Although there have been reports of some success with the use of a "stainless steel" charging cable. Apple only seems to sell one separately. Are we sure this is a "thing"?
You said purchased July 2018 so your watch and charging accessories are still in warranty. If you can get it in any way reproducible take the whole collection to a Genius Bar appointment and try to demonstrate it in person. I’ve seen charging cables swapped out free in the Apple Store here just on suspicion of a fault.
I'm experiencing the same problem.
Last night I tried to charge the watch the first time over night, not in the evening as before. As soon as the battery was full, the watch startet chiming and turned the display on and off every 1-2 minutes.
Apple Watch Series 5 Stainless Steel, WatchOS 6.0.1, charging via Nomad Base Station Apple Watch Edition.
I got the base station on saturday so I have some days to test and to return it.
Here in the office I tested this morning the original ss charger with my series 5 and my series 4. No chiming.
According to Nomad the Base Station seems compatible ?
At home I'll continue my tests.
My Apple 3 watch was doing the same “dinging” and so I was charging during early evening. Inconvenient. Then I got the charger that came with phone and no more noises while charging! Apple obviously only wants us to buy only their product. Or else, they will make you “pay” in another way!
And now it's started happening with me. AppleWatch Series 4, watchOS 6.1. A couple of nights ago it started doing this on the circular Apple Magnetic Charging Dock, chiming over and over again after being on the charger and hitting 100%. A little while ago I gave the watch a hard reset; it's on the charger again now and isn't making a noise. I'll report.
I bought a used steel charger
the beep disappeared
certainly it is a software bug (before watch os 5 no prob) but I cannot trust Apple addressing this issue
As I've said previously OS 5.1.2 update was my problem it was fine before the update, therefore it must be a software issue for which Apple need to issue a fix.
People in some other forums are saying it was 5.0.1 when it started for them. I have no idea when mine started, but it's been months.
Regardless, I still don't see what would be happening in software that would cause it to be fine on one charger, but not on another identical charger. Very weird.
Apple is trying to find a software fix. They claim it’s a software problem (yet can’t explain why it only affects some people)
They agreed to replace my watch, then sent mine back when I sent it in for replacement.
I’ve been dealing with this for 2.5 months now.
This issue just now started right after I upgraded the OS to 5.2 on an S3 watch. I've had the watch since mid-Dec.
The chiming is starts even before the battery gets to 100%, around 85% or so.
Appears to be a software issue. Have not changed the charger out for any others, just using what came with the watch from the factory.
Will try to just turn off the watch and charge it and see if that silences it, but I fear Apple has no cure based on all of the replies I'm seeing here.
Demand a replacement. If there’s a problem and they can’t fix it, it should be replaced. They can claim it’s a software problem (and they have for almost 2 years) yet the issue still seems unresolved for many people.
Why should those with the issue have to deal with it while they (try) to figure it out?
I hate to disillusion you Chris, but I tried that too. I've tried everything - different types of chargers, hard reset - basically, you name it, and I have tried it. I believe it's a software problem and something Apple needs to fix.
It's not a reminder that it's done charging. It's a glitch. They didn't program it to do that.
It's only supposed to ding when you first put it on the charger.
