My experience with my Pixel 6 Pro is also amazingly snappy UI and great software, but absolutely crap battery, the worst of any smartphone I've ever had (and I suppose that's the chip's fault, because the battery itself has a normal amount of mAh). The model is also quite unreliable, to the point that I sometimes disable 5G and 4G because they do more harm than good.
I could live with the modem issue (3.5G is OK for 99% of my smartphone usage anyway), but having to care so much about battery running off is a quite important drawback for daily life. The fact that they seem to be keeping the same path with the chip makes me think that I'll have to look for another brand for my next phone.
