The Pixel 9 series has way better battery life, but it also delivers improvements to charging. One of those improvements is that the Pixel 9 has higher requirements for fast charging, helping you better know if your charger is truly up to speed.
Super fast charging damaging your batteries hasn't been true for a while. Charging standards like supervooc push the heat to the charger and charge two battery cells simultaneously. This reduces heat generation significantly than if you were to charge traditionally. My 15w samsung smartphone generates much more heat while charging compared to my 67w realme smartphone which stays cooler even while charging at quadruple of speeds.
Other smartphones slow the charging rate when the display is on. Phones which support supervooc can charge your phone at the same speed regardless of display being on or off.
My phone also has a smart charging feature where it can slow charge the battery at night & limit it to 80%. In the morning just before I remove the phone from the charger it will finish charging to 100%.
My OnePlus 8T lasted over five years and to be honest would probably still be ok, and it charged at 65 W. That's way faster than the pixel 8 pro I use now. Batteries have gotten way better than they used to be.
That's fairly normal for any battery, regardless of charging rate. I have a OnePlus 9 and haven't really noticed any huge battery degradation, my phone still easily makes it to the end of the day.
And if not, I charge it for just a couple minutes and get half of the charge back. It's pretty great. The newest phones can even charge at 100W+. You barely need to bother plugging it in overnight, just plug it in when you take a shower or have breakfast or something.
