Does anybody know what a ”normal” battery health reduction should be?

I’ve had my Apple Watch series 5 since March and its already down at 93%
 
I have had my S5 for 13 months and it is at 91% battery health.
Which seems a bit disappointing since I do not use the battery heavily, and seldom finish the day with less than 40% charge remaining.

Thanks. So mine seems to be on the same rate as yours then.
 
The Series 5 I got in Nov 2019 is down to 88% so I'd say your battery's degradation rate is more or less standard.
 
My Series 5 that I purchased Nov 2019 has a battery health of 93%. I charge it about every 1.5 days as I don't use always on display. When AOD was on I would have to charge it everyday and I have found Watch OS 7 has taken a battery hit.
 
My now 27 months old AW4 is at 87%, for the first year and a half I charged every other day, now daily and it’s between 35-45% typically...
There’s a long thread about watchOS 7 and battery life, if you’re interested search if that and get some more info...
 
Sample of one but my AW4 received 12/19 from APPL as a replacement (1st AW4 wasn't repairable under warranty) today shows 96%.

ETA > used daily, all rings closed 6 days a week & charged nitely while sleeping.
 
I got a 44mm series 5, Titanium, and it was on 99% a month or so ago. I checked it yesterday, and to my surprise it's on 89% That put me in some serious depression today. you pay all this money and its just a timer ticking down and then it won't work.
 
no electronic device that gets charged every 2nd day (or daily, or every 3 day) and is used on a daily basis will have a "battery health" of 100% after 2 or 3 years. I am NOT saying that you guys who report this are not telling the truth, but if your device displays that now, don't be surprised if you see a sudden 10% or more drop ...
Li-based rechargeable batteries age, ongoing chemical reactions during dis-charge and charge will lead to that.

Agreed. That’s a bug with the Series 3 or 4. The battery health meter isn’t working. It’s like a car where you fill the tank and after driving 100 miles it still shows full. The problem is the meter.

I don’t think the battery health meter works very well on anything prior to the Series 5. My theory is that the meter is calibrated for the Series 5 and up. Even though it shows on older watches, I don’t think Apple has calibrated them properly yet. Or maybe never will since that feature didn’t exist when those watches were introduced.

Yea, I’m not sure either, all I can report that on my S4 it reported 90% when I first tried it and now it reads 87%, both realistic imho... but Apple is always a little on the “brighter” side as evidenced on Mac when compared to coconutbattery. Would be nice to have such a tool for the watch...

My daughter has a three year old Series 3 that still shows 100%. I know that’s not right. I don’t think the battery health meter works as well with older watches that have a different sized battery or different discharge rates from the newer watches. The Series 3 has a battery that is almost 20% larger than the Series 4. And the Series 4 doesn’t have an always-on-display which affects battery discharge. It looks to me like Battery Health isn’t accurate with older watches. Maybe never will be.
 
Series 6 coming up on 4 months old still at 100%

Series 4, 44mm, I got it on launch day. So about 2.5 years? Health shows 88%. I never get it close to zero, but since I do sleep with it on, it hovers from about 20%-90% state of charge.

That range (~20-90) is actually OPTIMAL for battery life ...

Right, I make an effort to keep it in that range :)

Previously, I didn't sleep with it on, so it would often be at 100% (every morning). Now I charge it while I'm working at my desk and might take it off the charger when it's 75%, maybe 90%, just depends.
