I wrote about battery drain in response to another user who had issues on Graphene, even though this is a general Pixel issue, and has nothing to do with Graphene. The modem chews through the battery if you don't have good connectivity, although I'm not sure if that's still a big problem with the 7's and 8s. It definitely is with the 6.

Personally, I had problems with adapting to the "don't try to be a power user" philosophy of Graphene. I was used to flashing ROMs, rooting and customizing the hell out of my previous smartphones. Then I suddenly had a device which just... worked. It's still an odd feeling, but I got used to it.

Just wanted to add to the other users unique experiences. From the perspective of someone who was a "the only good phone is a phone which is one small mishap away from being bricked" kinda guy
