First of all, IodeOS has been flawless on my FP3–thank you! Very excited to have Android 13 now.
But, I have been getting significant battery drain from “mobile network” since updating to 4.1. Did not have this issue with the Android 12 versions. I have not tested anything yet, but wondering if anyone else has noticed problems, and I will start testing why this could be the case. From some research, it seems like this may be a known problem with Android 13 with some phones in some builds.
