What phone you get. It’s sound like a Samsung have you seen if there is custom ROM you can run? https://wiki.lineageos.org/devices/#samsung
Also a lot of services like Location Protocol, google services frame, downloads manager, contacts. Are necessary for your phone to work at all. Turning them off and on when using them would destroy your battery.
Endless Os is solid! It’s my go to for ppl who don’t know jack about Linux. But it’s also just a really well put together distro.
My favorite feature by far is just Auto updates. It’s the only distro I’ve used where Auto updates just work. Everything stays updated zero tweaks required no interruption of workflow. It’s honestly so good at it that I forget that it even updates. And that doesn’t just go for the OS that goes for apps too.
It also runs well on just about any hardware I’ve ever put it on. I just put it on my buddy’s Toshiba satellite laptop that’s rocking an I5 4200u and a 5400rpm hard drive. Takes a second to boot but doesn’t miss a beat once it’s up and running.
It is very flatpak centric but if you’re looking for that Chrome OS feel it’s about as close as you can get.
