On my Pixel 1, I wasn’t careful about the battery, regularly draining it fully and then charging it to 100% (and leaving it on the charger for extended periods) and after 18 months, I was already looking into getting the battery replaced due to greatly reduced capacity.
At a friend’s suggestion, I installed Accubattery which alerts me whenever the battery is about to go outside the 20-80% window. I almost always unplug from the charger when I get to 80%. That second battery on the Pixel 1 kept most of its capacity for 4 years. Now my mom has that phone, with the same battery, and even though the capacity went down a bit since, it’s more than enough for her needs still.
