6 hours has been my norm on the 7 Pro I think. A couple days ago when I checked I was at 3 hours screen time at 60% battery. My issue with the battery has been idle / standby drain. I'm losing 10% overnight when I don't check the phone for 8-9 hours. My Pixel 3a behaves the same way, iPhone really is the gold standard for standby battery drain (or lack thereof).I've read on XDA guys getting great battery life on 7 Pros, like easily 6+hrs Screen On Time, more like 7h to 8h with the right settings. I can't get anywhere near that on my 3 X, and was hoping the 4 XL would see a huger improvement in battery life, yeah the SD855 is more efficient, that helps, but also a large battery always helps too.
I still think that the smaller Pixel 4 battery will be insufficient if these specs hold true. I'd still get the phone if everything else about it is A+. My experience with the 3a has been so much better than my old 3 / 3XL. Auto brightness works out of the box, to name one feature that always plagued my Pixels. There is no static or chirping or any noise at all during phone calls in the earpiece speaker. Every bug I experienced in older Pixels has not been present on the 3a. Hopefully this bodes well for QC with the 4 / 4XL.
