I updated to Portico last week. My battery became much worse than it was before the update. 5 minutes on Baconit would drain about 7% of battery and it'd only last about 11 hours or so before it got to 30% battery life with very moderate browsing/use. In addition, I was one of the people who got hit by the flickering brightness bug with Portico.

I decided to reset my phone to hopefully fix this issue, and now I'm in a "worse" state. I can't attest for battery life as it's been about 2 hours of total use since I reset it right before i slept.

It restored to Portico instead of just 8.0.0 (whatever the firmware number was).
I can't adjust the new settings. I have text replies, but Brightness adjustment when battery saver and other things are inaccessible.
