A screenshot of the battery usage stats.
You may find that something else takes over role of the Google app in causing drain. On occasions, when I have had excessive Android System drain, I've fixed that one way or another, only to find that Google Play Services takes its place as the drainer. I don't recall that I've ever had trouble from the Google app, but whatever app is showing as responsible, the root cause can be difficult to diagnose. Some app may be requesting abnormally frequent location reporting, for example, and Google Play Services might then oblige, that being one of its functions. Without actually being the root cause, Google Play Services would then show in the battery usage stats as apparently responsible for the drain.
I'll link this thread again to the team members, who may be able to make suggestions.
Incidentally, I'm not sure how you uninstalled the Google app....I have only the option to Force Stop.
