Also, do you need that long battery life? If yes, ARM or really new intel processors with energy saving cores seem to be the way to go.

I don’t have experience with it myself. But what I’ve read so far is, that the Snapdragon support by Linux is quite bad. Not sure if I would recommend that…

But the new Intel CPU’s are great. They are quite efficient and performant.

My guess is, that they will offer a new Thinkphone model with GraphenOS to target business customers.

But of course I don’t know it, just guessing.
