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.

I don't get it
Why would you want your battery to change so fast? It gets hot and isn't great for the battery. I just want all day battery life and then a trickle change overnight. My current phone does that
- BC you forgot and you got 5 min before you got to leave.
  Fast charging is best feature we got in last three cycles IMHO
- I'm just waiting for capacitors to replace batteries. I read a really promising article recently and it said they figured out how to make a capacitor hold more energy much longer which means when that comes to market leaving your phone charging overnight will be a thing of the past.
  
  Capacitors replacing batteries like this, similar to nuclear fusion power, is always only X years away.
  
  That's not going to happen

45W is still not really fast though, Moto is at 50. Wirelessly. Wired at 125.
But to be fair, Apple is at ~30W. And that's just sad.
- Isn't apple at 18W?

Raises the bar? Don't the realme phones come with ridiculous fast charging like 1 kW?
(The number is an hyperbole)
- Realme tested a 320W charging brick recently. It charged the battery in under 4 mins.

And lowers the bar for overheating and longevity.
- I just got a new phone (reluctantly) and it feels like 90% of the "features" are useless marketing gimmicks.
  Most people still use their phones for very similar purposes to 2016 or even 2012. Instead of providing properly optimized software and batteries that last weeks, we get these huge heavy expensive unoptimized pieces of techno garbage. And of course they need fast charging, otherwise you'd be wired to a charter half the time.
  I'm practically forced to spend 10€ per month, even if I'm hesitant to buy new stuff, just to have a reasonable phone. That's crazy.

  What? Who forces you to pay that?
- And performance, and privacy, and …

Don't use these super fast charging rates. They aren't good for your battery.
I got an ASUS ROG phone because you can set it to charge slower, and stop at 80%. The battery longevity will be better.
- 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.
  
  It probably lost 20+% of it's max charge in that time. That's what I'm talking about.
- 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%.
- Things like splitting the battery into multiple cells helps with this.

That bar is still way slow. My phone can charge at 100watts, 0 to 100% in less than 30 minutes. Most American brands are way behind.
