Yes to both. I have, however, disabled my Google Play Framework to no avail.

The battery drain that you have might not be caused by the firmware after the update, my battery was charged over 7 weeks ago and is now on 35%.
Screentime was over 50hours, and I guess at least 10 more to go.

I do keep my wifi off, and only manually connect once a month perhaps to synchronize time. I have the Google play store connected, but I have frozen the Google play app, so I only unfreeze it and update when I know there is an update for the reader app that I use. That doesn't happen often, and I can see on my other Android devices if there is an update. It might be that the reader app doesn't use the Wacom layer so maybe it's polled a bit less? I use the AlreaderX beta, and often it is on night mode, not sure if that saves power. I have read that the Google Playstore app uses a lot of power, I can't reproduce where I read it though.

I use no other ways to connect to internet or bluetooth devices and I don't use other apps than my reader app, though I have 2 other apps installed - both frozen.
Thanks for sharing some actual usage data. 50 hours screen on time is very impressive. Wonder what mine would look like if I kept the Wifi off as well. I keep the Wifi on mainly to sync Moon+ Reader and Pocket and access documents on Google Drive. I’ll try putting my device into Airplane mode when not using those apps to see how it affects battery.
