2. Wireless Charging - I have come to rely on wireless charging around my house, so I need a phone with it.
3. Great battery life - This should come standard. With WiFi 6 helping to reduce usage and with good software enhancements to make my phone last longer on a charge along with last longer.
4. Great Support - I would love to see a way for me to replace battery or screen or whatever through Google. Unsure, if they have something like that now, but that would be nice.
