I currently have a Fenix 6X Sapphire running on 12.77 Beta. I've historically had very good battery performance (lasting 2 to 3 weeks), including on this beta.
At night, I keep my phone in an adjacent room (one wall away) and about 30 feet away from my bed. Last night I accidently left my phone in a completely different room about 40 feet and three walls away. My battery drained from about 90% to 11% overnight. My phone, which will typically drain about 6 to 8% overnight if left off of the charger, appeared to drain from 70ish % to 30%.
I fully charged the watch this morning and about 12 hours later, it is at 97%, which is what I usually experience.
I've never experienced that before and wanted to share this experience in case it is helpful to anyone experiencing battery issues.
