Same here. It's not uncommon, though, with certain iterations of a beta. Submit beta feedback so the team can access your logs and resolve this in a future release.
I'll put some context here. I had my phone at 100% SOC and hooked up on a USB-C Samsung Cable in my E-300 using Android Auto on my way to Austin from Dallas today. By the time I got to Austin it was down to 83% inspite being connected all the way through. Compare this to using the Official version of Android 14, I was able to maintain a 100% SOC throughout my trip to Austin.
Mine as well. Gut feeling says standby drain got worse and phone warms up more often but giving it benefit of the doubt considering it's the first beta.
