Graphene uses a lot less power than the Google OS because it isn’t doing much “background work” like tracking and locating.

You all recommend this graphene thing on pixel? I, super unfamiliar but need a new phone soon. I wfh so honestly would be down to try something totally new ie pixel.
GrapheneOS is what we call a custom ROM. It allows you to de-Google your phone. It's custom firmware for your phone. You need to unlock the bootloader and flash the new firmware. It's not hard to do on a Pixel, especially now a days. It's all point and click. Super easy.
Pixel is the best phone to use with graphene. Mine is a Pixel 4 (not the phone I’m currently using)
