TL;DR
- Android 15 is preparing to tweak the threshold that determines whether a charger is seen as fast, from a measly 7.5W to a more reasonable 20W.
- The operating system has long considered any charging speeds of at least 7.5W to be fast, which is far, far below what actual fast chargers can deliver nowadays.
- The change isn’t live yet in the latest Android 15 beta, though, so chargers that deliver 7.5W of power will still be seen as fast on Pixels.



Why not just show the charging W on the screen instead of ‘fast’.
Android is catering to the general public. The average user would easily understand fast, slow and normal. 20w, 68w, 5w not so much. But, I agree not having to use apps or 3rd party cables just to see the charging watts would be great. Even a Dev flag to enable the feature would be cool.
That’s ridiculous. People have been buying light bulbs based on Watts for around a century and understand that higher W means brighter and more power.
Bigger number go faster
You make it sound like a joke but that’s literally all it takes here.
Because the less tech savvy people will be confused when the battery starts getting full and charging speed tapers off which will lead to complaints about their 20w charger only providing 3w of power.
Then give a setting to enable it in the developer settings.
Seriously. This thought occurred to me the other day when I plugged my power bank into a car’s charging port to check the wattage and wondered “why the fuck can’t my phone just do this by default?” Do we actually not trust people to understand higher number = faster?
Charging… the car?
