Anyone else experiencing this? Even with my phone screen turned off, batt drain for just a 30 min drive is 15-20% 😡. For context, my s21u is driving (no pun intended 😁) my car's head unit wirelessly. First time using such a setup.

Thanks but batt health is good. Whenever I start AA wirelessly/head unit server I'm sure there's no other apps running. I did observe that whatever's running on my car's head unit (HU) is also running on my phone, albeit phone's screen is off. Methinks it's just a type of mirroring (thus the batt drain) and I guess that's just how wireless AA is
