I'm not quite 3 months into my series 5 purchase and the battery health is 96%, is this something to be concered about?
 
The battery health is only an estimate and isn't always accurate. Don't obsess over numbers as everyones usage is different and nobody can tell you if your particular experience is normal. Apple won't consider it a problem unless it reaches 80% before the warranty is up so as long as the Watch works normally I wouldn't worry about it

My AW5, which is approximately 16 months old, is down to 83% battery health. Pretty sure it will be getting a battery replacement before my 2-year AppleCare+ warranty expires. Battery health seemed to take a nose dive after WatchOS 7.

I have noticed this as well. I'm really hoping that WatchOS 7.4 fixes the battery issue. My battery when I took it off for the night (around 8:30pm) used to be around 40%. Now it's usually around 20% which isn't too much of an issue, but I'd much prefer the battery be at 40% by the end of the day in the event that I'm out (battery health is at 100%).
 
Stop looking at it. Apple wants you all to panic and buy a new watch when it gets low enough, meanwhile the actual time per charge remains the same. Stop buying into the scam. It's just that--a scam. Brought on by all that jazz about the 'Apple slowing down devices through iOS updates' crap.

Lithium Ion battery tech is miles ahead (re: longevity) compared with NiMH or dare I say, Ni-Cd. Even S0 watches still work--that's already 6 years.

I don't need this stupid "feature" to tell me when to worry--if my watch starts going from a day per charge plus to no more than 4-6 hours, then I worry. Not because Apple places a glorified deathwatch counter on my watch.

Well I am currently using AOD with raise to wake and am getting 1 day's worth of charge (one run with airpods a day). This is quite different to 2 days on my AW4 and 2.5 on my AW3, I know Apple says 18hrs for all of them but it is drifting more into the world of inconvenience for my pretty much new S5.
 
The operative feature affecting S5 battery life is AOD itself. I got everything turned on, and I go a full day (today well, it was 26 total hours as I slept in) but sometimes I wake and it reports 0% charge yet oddly stays on. Never once have I plugged in an Apple device and had it show the Apple logo as if rebooting from a dead state--but many Androids have ended up that way. I don't even worry about the charge level anymore. Even less care about the 'health' since Li-Ion tech is darned good for longevity. Got tools at work that are well past 2 years and keep working much the same--can't say that about the now-dead DeWalts that relied on Ni-Cd and won't even charge now.

Also, keep in mind if you keep updating apps and the OS, that's going to demand more from the resources including power. Stop updating and you won't experience slow downs or limited battery life over time.
 
Like the previous poster, I've had my 40mm S5 for roughly 19 months, too. Current battery health is 83%. The moment I break the display or battery life suddenly tanks, I'll consider replacing it. But for now, it fits my needs and it lasts my entire day.
 
3 months short of 3 years with my Series 3 and I'm at 99%. Wear it daily and charge every night. It doesn't do a lot of heavy lifting though- texts and workouts.
 
AOD will wear down battery health nothing can be done . Just save up for the battery replacement

Just for context in case it's helpful, I have an S6 Cellular size 40, and it's at 96%. I got it on launch day, so it's about 8 months old. But I don't notice any real difference in day to day usage/battery drain. I run and use it at night as well to measure sleep.

Since I posted this on April 21, 2021 my battery health dropped to 82% and has stayed there for the last several months. 2-year AppleCare + expired but went month to month in case battery goes below 80%.
