I did have to reinitiate my Pixel 3XL after changing the battery. All my information stayed but did have to set up again. Had some trouble getting battery and wireless coil plugged in. So %#*@ tiny. I was afraid i bent the pins pushing down when not perfectly alligned. But a sigh of relief when I turned it on, BUT, i did have to charge it first. Battery was 100% dead. I hope that's not a bad sign. Gotta figure, phone is 5 years old. So probably is the kit.
