Anyway, I don't use my phone very much as you see in my battery log, but when I travel (quite often) I really need location to be fast and accurate (battery friendly too).
I tested GPS a couple of times and not the best experience without Google Services.
I came from LineageOS with MIcroG and there, at least, mozilla unified kind of worked decently.
So, I only have 5 apps from the Google Play, 2 banking apps, Instagram, Whatsapp and Google Maps (plus Signal).
Should I uninstall them all, install Google Services and then reinstall them to take advantage of the push notifications and location services?
