When watching phone reviews online (YouTubers and tech magazines), I have noticed that most tech reviewers only measure the charging speed while the screen is turned off!
But a historical weakness of many fast charging phones is that the charging speed is severely throttled while the device is in use. Fast charging thus only works when the device is in stand-by mode or powered off, which means that one can not use the device and charge fast at the same time. Screen-on charging speed is equally as important, because not being able to up the battery quickly while using the device at the same time is very, very inconvenient.
I have done measurements with several historical Samsung flagship devices such as Note 5, S6, S7, S8, Note 8 and Note 9, and noticed that the charging speed is close to 15 watts (as supposed) with screen off but miserable 6 watts total with screen on, which would have definitely been a relevant point for tech reviewers to address.
Whether there is a good technical reason or not for mobile phone manufacturers to add such a restriction, e.g. heat, it should still be addressed in mobile phone reviews.
I hope that mobile phone reviewers who read this are going to address this important point in future reviews.
