After I had my Pixel 3's battery swell twice, I figured leaving it on the Pixel Stand all the time likely wasn't a good idea... even though it was advertised for such purposes. Been a lot more cautious with my Pixel 5.My Pixel 3's battery ain't what it used to be so I usually have to charge nightly now. When I'm working from home I have the tendency to plop it on the wireless charger and use it as a desk clock but I'm guessing that topping up of the battery isn't the best thing for it.
That being said, the iPhone's I've had for work, they seem to really slow down the charging past 95% or so, not sure why Android hasn't adopted that.
