I'm still using a Pixel 5 with Android 11, so far so good. I used to be a hardcore Android fan, but I don't really like where it's going, at this point I'm almost rooting for a USB-C iPhone SE.

(edit) Regarding the specifications:

  - don't care for 5G, 4G has better range and better power efficiency
  - don't care for a second rear camera, invest more into the first
  - 4h SOT seems like a pretty low target, the Pixel 5 can probably do 8h easily
