Having looked through the forum and searching posts I didn't really find what I was looking for although what I did seem to see were individuals with better performance than I am seeing.

Bit of background, I had a series 5 up until last week which pretty much overnight decided to no longer last the day. Prior to this I had never even looked at the battery percentage or had I had the 10% warning. It pretty much aligned with the installation of WatchOS 9.5. I tried un-pair and re-pair from back up tried the same as a new watch. I hadn't changed any other settings such as raise on wake, background refresh all these were still on as per my previous settings. Battery health with this watch was at 79% ~ 2 years old.

So, with this in mind I could of sent it to apple for £85 and had a replacement or go for a new watch which I decided the latter. So I've had it for 3 days now, first day I ignored its battery performance as it hadn't had a full charge.

Second day performance was a little better however I would still only get around 12 hours before being on the last 10% remaining, bearing in mind my S5 would easily go 15+ without me even checking the battery %.

Third day (today) I've carried out a 2.5 hour out door cycle ride (without using workout) so would have been tracking HR etc. It's currently been on my wrist for just under 13 hours and has 8% left. I have seen some people getting 24-48 hours from a single charge I am no where near this, although I am aware of the 18 hours Apple say.

Thanks!

Do you have your phone with you on your workouts? My 4 really goes through battery when it can’t connect to my phone. It takes a while to charge, but I can do a 1 hour walk and a 30 minute weight lifting session and use sleep monitoring at night and have 40% battery in the morning. Perhaps you do a lot more with your watch than I do with mine.
 
I've gotten approximately 48 hours on a single charge (45 mm, cellular, no iPhone nearby) although this only happened once when I forgot to charge overnight.

Yeah, my phone in my back pocket of my jersey so apart from just being a watch and the odd notification it's purely doing nothing more than read my HR.

No iPhone nearby, I guess you'd of got zero notifications, do you have always on display?
 
Just to update this thread in case anyone finds it by search. I have in fact found the issue which has been draining both Apple Watches. I found this by noticing my phone battery has been draining faster than normal and upon looking through the usage, Home app was running in the background for around 9 hours in a 24 hour period (approx 50% usage).

With this knowledge I tried to find a way to reduce this and although lots of people have the same issue, the only thing that solved it for me was to ‘remove home’ from the app.

So with this change I’ve been using my series 8 for around 18 hours per day and at the end of the day it is around 50% remaining, and as a test I’ve been testing my older series 5 which I have been wearing today for 9 hours which has 59% remaining. By now I’d be on the last 10%.

So, I now have a series 8 for no real reason other than thinking that it was to do with the 79% capacity… yes I know I could have just got a new battery but it still wouldn’t of fixed this issue or allow me to test as above.

Hope this may help someone in future, next I’ll be adding my home sensors/lights/cameras and watching the usage.
