As suggested I've been using the 10/24 build for a couple of days. So far I'm very impressed. There are a few things missing in this ROM, so I added some further customizations via magisk + xposed and now it has everything I want.
It's true. Battery life on the 10/24 build is noticeably better than other A12 and A13 ROMs I've tried (CrDroid, Flamingo OS, etc). And this is with AOD on, so it would probably last even longer with AOD off. It's still slightly worse than stock OOS tho in terms of standby drain.
That's my homescreen with Pixel Launcher Extended mods applied.
Also added face unlock using this.
