I'm doing something similar on my Pixel 2. In the end I have very few apps that send personal data to ad companies (I've blocked as many ad and tracker networks as I could), and I've prevented most apps from showing me notifications unless I really want them. You'd be surprised how much battery you save with all those things disabled.
