Fast charging gets a new definition on the Google Pixel 9 series
The Google Pixel 9 series has brought some surprising new changes, and one of them is how it defines "fast charging." Google Pixel 9 Pro XL users noticed that the familiar "charging rapidly" message was missing from their lock screens, replaced instead with an estimated time until the phone is fully charged. This change initially led to confusion about whether the phone was truly fast charging or not.
It turns out, the "charging rapidly" message hasn't disappeared entirely. It still shows up when using the Google 45W USB-C Charger, but it's not exclusive to that charger. In fact, any charger delivering at least 20W of power will trigger the "charging rapidly" message on the Pixel 9 series.
Also the Pixel 9 Pro XL annoyingly removed the "Charging rapidly" and replaced it with an ETA. While the ETA is useful, I can no longer easily tell if I'm connected to a "fast" charger or not.

Maybe the Google 45W charger does still show "charging rapidly"? But nothing I've… pic.twitter.com/69hDi5WiGZ
This means older chargers that might have been considered "fast" on previous Pixel models may not trigger the "charging rapidly" message on the Pixel 9. It's important to note that this doesn't necessarily mean the phone isn't charging quickly; it just means it's not meeting the new 20W threshold.
While Google's official 45W charger guarantees the fastest charging speeds, any fast USB-PD PPS charger delivering at least 20W should also trigger the "charging rapidly" message. It's worth noting that Google's phones don't use a proprietary wired charging standard, so you have flexibility in choosing a charger.
