With an SD 8 Gen 1 the SOT has never been great. I’m using Wi-Fi most of the time and even then it’s draining as if I have two SIMs draining cell data.

Are there any Routines or settings you recommend? I’ve already done all the standard things like deep sleeping apps, power saving mode (usually when under 50% with a Routine), updates and data intensive stuff only over Wi-Fi, and have cleared the cache partition/factory reset.

What about the setting in developer options to turn off mobile data when on Wi-Fi, would that help?
