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.
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.
