Why is my Apple Watch 10 battery suddenly draining so fast?

I received my Apple Watch Series 10 on September 20 2024. Worked perfectly for one week then on September 29, it suddenly went from 80% at noon to 20% at 5 pm. I am tracking the time now but I can see that it is significantly losing power every hour. I rebooted, but it is still losing significant power. Unless I can come up with a solution, this watch is going back!

My s10 has been getting 3-4 hours of battery life with minimal things running.


The guy at the Apple Store told me it is the phone software that is jacking with the watch. I got a 16 pro late October. He had me reset to factory and re-pair to see if it would fix whatever is causing peak watch battery use. Funny thing is that my iPhone gets 2-3 days of use if I don’t kill it on social media.

Haven’t changed anything after the last update, which was watch os 11 on the 20th of September and first of all I was positively surprised that watch lasts around 30-36hrs. Two days ago it went from 100 to nil in 18 hours and today died after 14 ish. Definitely something going on in the background, like I said i didn’t change anything and the way I use the watch.
