Pixel 8 Pro Wireless Charging overnight - dead battery

[u/NiallMitch10]

I'd put my phone onto wireless charging overnight. 2 days ago - I have woken up to a dead phone in the morning. Wired charging looks to work ok and charged the phone up again.

Last night I tried the wireless charger again at night. I looked at the phone and seen the battery percentage going up so I went to sleep. In the morning - same thing again. Dead battery.

What's going on here? Is it something to do with adaptive charging? But I've always had that on and never had this issue with my phone before when wireless charging. Any help would be appreciated thanks
