What causes Battery Drain on my Apple Watch Ultra 2?

Hello all,

I’ve been dealing with this Apple Watch Ultra 2 issue for about 2 and a half months now and I’m mentally exhausted and stressed.

I’ve been to the Apple Store on numerous occasions. They’ve ran multiple test and sent my 1st Apple Watch out to depot, I have Apple care plus I used it for an express replacement device.

Fast forward, I received my new replacement Apple Watch Ultra 2. I had it for (2) days and it decided to do a boot loop and eventually died and never turned on anymore. I go to the Apple Store and they give me a new watch in store, mind you I’m currently on my 3rd Apple Watch Ultra 2.

I’m back to square one with the battery drainage once again. I’ve done multiple hard resets and unpaired and paired it back as a new watch and not restore from back up.

I’ve turned OFF background refresh and Smart Stack, I’m always connected to Bluetooth, either at work or home. The ONLY notifications I keep ON are text messages and call notifications everything else is turned off.

My battery only last on average 8-10 hrs a day.

Suggestions are GREATLY appreciated please and thank you!
