Subject update is draining my phone 50% faster than prior to update. My phone is a Samsung Galaxy S8+ that has an OEM replacement battery that is less than three weeks old. The phone was working as new with the replacement battery. I have not changed my phone usage since the update.
One change that I notice in the phone's Settings is found in "Settings/Google/COVID-19 Exposure Notifications". I don't recall this "service" on my phone prior to the update. I believe that this new service is monitoring my location 24/7 (notwithstanding that it is set to "Off"), perhaps for COVID-19 tracing and that this is what is draining my battery. Beware: Big Brother now is watching your whereabouts via this nefarious update.
