I have a 6 Pro that I got in November. AccuBattery says my health is at 99%. I use my phone for probably an hour a day and charge every other day. You don't let your phones sit on their chargers while at 100% battery, do you? I'm fairly sure that's what killed the batteries of my last two phones. My Pixel 3 was working fine until I started working from home and the phone rarely left the charger. After 3 months, the battery started swelling.
