Guys, I've fixed my S7 Edge Oreo cell standby battery drain without flashing a new modem. All I did was to clear Google play services data and then dalvik cache. Just go Google play services, manage storage, clear all data (you'll lose your Google search data and your phone settings backup, which you can backup the data again, so no stress). At that go to recovery and clear cache. My cell standby is now at 1% level. I'm from Finland, so I'm having the Nordics modem in my phone. I hope it helps.

I forgot to mention that I've also installed the August security patch.
