Apple Watch Series 10 battery drain on WatchOS 26.3

Hey,

I'm currently running WatchOS 26.3 on a Apple Watch Series 10 GPS. My Battery Capacity is 95%. Normally my watch would last 2 days. We have 3 watches and they all have the same issue. It seems that the batteries are draining insanely fast. Now i'm happy if they last 12hrs.

Anybody else seen this issue and have been able to resolve this?

Energy saving does almost nothing.

I have power cycled my phone and watch without result.

I have reconnected the watch to the phone and did a factory reset.

I disabled notifications that I didnt need and even tried to disable wifi without result.

I kept it for a full day on the charger to speed up if there were any background processes but it didnt improve.

Since its on 3 watches its not just a one-off. Anybody have any idea what to do or try?
