All day. Pixel 7 Pro.
Hammered towards the end of the day but I don't have to charge. I always charge on a low wattage which seems to keep the battery going
Personally I'd not upgrade from 6 to 7 but that's me. 6 was a bad year. I held off even though my OnePlus 6t was really dying - broken connectors etc.
See if you can make it to the 9 mock up start coming out and the prices will tank. Google seems to be chasing the best seller prize and prices crash early.
Don't buy an 'a' again.
