Recently I accidentally synced all of my music to the Apple Watch. It filled up the hard drive of the watch, consequently the battery would run out by 4pm with no activity.

This doesn’t explain battery health but if your watch ssd is full, it might be contributing to a depleted watch by the end of each day. Batteries don’t like that stuff.

I can't think of a reason this would be related-- the whole point of flash storage is that it requires no power to maintain.

It's possible that it's doing some clean up and indexing after the massive upload and things will return to normal once its done.

It’s a known thing that charging to 100% all the time and letting it on the charger will wear the battery more. That being said by the time the battery dies you’ll want a new watch.
It has little effect on my 9 month old iPad Mini 6.
 
My AW series 4 that I bought new is still on its original battery and its life shows 88%.

I leave it on the charger overnight and do not baby the charging process

Then explain @fitcious experience.
I can’t… there are too many variables, including incorrect battery health reporting. My 2016 MacBook Pro 15” was never below 85% battery health. Guess what? The battery just died. It went from 85% to 0% overnight? Not possible. Mac OS was just reporting the wrong info. I suspect the same thing with these older Apple Watches. One day it will just die and they will be like but the health was only 88% how can this be? LOL

True very true. I remember my 2012 MacBook Pro battery software (tech Tool Pro) said it was in great shape. Unfortunately I did not know it but the battery blew up inside the MacBook and only a computer tech told me this. So the battery was definitely not great.
 
My 15 months old gold SS S7 is at 92% at the moment.
I usually charge it to 100% at around 30% and I keep it turned off when I‘m wearing one of my others.
 
I’ve had my series 7 for a year and it’s at 88% life. Is this a healthy discharge? I take care of it like a baby.
Have a Series 6 and it also was at 88% after 11,5 months. Now it’s 80% at about 2,5y. But even tough I wear it all day and night, brightness at middle, always-on is on and it still is able to support me about 22h which is fantastic. Prior I had a Series 0 which got updated to a series 1 due to battery problems and both were unusable after two years with the battery lasting about 8h.
 
I do not understand why yours decreased so much and just a year. My SBTi Series 7, purchased at introduction, still shows 100%. I charge everyday, do not use the always on screen and track outdoor activities each day.

Dude… what do you want from this forum? Guys say you have a normal battery, you argue. Guys give you reasons for why there could be poor charging routines: you argue. Folks point out that if you have AppleCare, apple will replace defective batteries - no comment.

Either you do or you don’t have a defective battery. If you do, apple will replace it. If you don’t, you don’t.

I personally don’t think there is anything folks can do to affect battery life. Not in a significantly meaningful way. Some batteries just discharge and age differently regardless of use patterns.

Oh, and I don’t know that I buy the fact your phone and iPad batteries are 100% - at least if they are the same age as your watch.

If the software says that they are 100%, I would be more concerned about the software saying it’s 100% than the watch software telling me my watch is 88%. That seems more realistic afterall. I’d feel like my phone and iPad are lying to me.

There is no reason to be concerned here, but if you are - Take your watch and complain to apple. I’m sure they will tell you exactly what folks on this forum have already said and you can disagree with someone who can do something about it.
 
I’ve had my S7 GPS for 16 months and I’m down to 86% BH if that helps?! Like others I wear mine all the time except for a brief morning and evening charge.

Reasonably frequent workouts I guess (often just tracking walks and a couple of runs a week) but nothing heavy. I noticed BH plummet for a few months but it’s stayed at 86% for at least a couple of months now. I have AC+ so not too worried, but I have learned that the rate of battery degradation is not uniform or steady. Or it’s just very imprecise in the first place as others have noted!

I suspect it's not terribly precise. I don't really check it unless I'm not getting my "money's worth" out of a full charge anymore. On my old iPhone 8+ I did happen to check battery health before and after installing a major version iOS update. After the update, battery health had dropped by ~5% heh. Probably recalibrated health following the update or something, but I can see someone obsessing about that number panicking and claiming "planned obsolescence." I just don't think the number's terribly valuable.

FWIW, I have a day one s7 currently at 89% battery health. I'm not worried. It still gets through two days of usage when needed, which is good enough for me. Once it can't do that, it's time for a replacement.
 
The battery of my watch Series 3 from March 2018 is still at 75%. For me, It’s enough for about 30 hours use without workout, about 24-20 hours with 60-90 mn indoor workout, and about 18-16 hours with 60 mn outdoor workout (using the GPS).
Frankly I’m really surprised and even amazed that the battery is still that good after 5 years of daily use.

I got my Apple Watch Series 4 (44mm) as a refurb from Apple back in 2019. My battery is on 89%. I put mine on the charger at night and take it off when I get up in the morning. So it's always charged to 100% for the start of the day. I have done so for the last 4 years and just don't worry about it. I use it for at least an hour a day to record my exercise.

I have optimised battery charging enabled too.

I don't get why some people seem to be so obsessed with battery health levels.

I question the validity of the battery health indicator. Got a Series 4 fairly close to launch day buy, and it is reporting 98% health.....

Guess I got super battery here in mine.....
100% agree with this. I had a Series 5 that was at 80% Battery life. After a software update, it jumped to 87%. No way that those were both accurate.
