While companies like Oppo are pushing for extreme charging speeds in excess of 100W, 3C certification for Samsung's upcoming Galaxy S22 indicates that the Korean giant will be sticking to a more pedestrian 25W charging for the upcoming flagship.

The only thing I currently want from the phone is for it to last the whole day without charging, and 7 hourson the screen is not a whole Day. Whole Day is When I am stuck on a train for 15 hours without a charger, and I have nothing to do except browsing internet. Just make a phone 2mm thicker and pack all this space with battery. It can charge even in 2.5h.
Pixel 5a already does 15 hours of web browsing.
