Had my Pixel 6 Pro for little over a week, and after a few small hiccups, everything is going fine. First mistake was transferring all data from my old OnePlus 8 Pro to my new Pixel, which caused random reboots & phone kinda felt sluggish at times, and battery def was not that great.
I factory reset my phone, did an OTA update (manually), then manually downloaded all apps & manually restored the database files for specific apps and since then, battery has been great, no reboots (still monitoring) and no other issues. And the way I see it, with all new early adopters, the kinks and bugs have to be ironed out.
