I doubt such things..as these type of tests are conducted in well controlled environment..which is totally different from the real world scenarios.. In real world, there are so many factors which could affect fast charging like high temperature, moisture in your surroundings, screen display and resolution, real world voltage factor and many more.. Samsung, themselves tell their customers to turn off their device to njoi fast charging and that's really tough for most of the users.. These are marketing statements to promote their stuffs..Perfect example is our S10+, when I bought it, it was taking only 1hr 36 min..to fully charge my device and after that speed was gone forever..
I too have S10+ and S9+ but mine S9+ takes longer to Charge than my S10+ inspite of having Small battery and I've also set my S10+ resolution to QHD+ for best viewing experience ...
That is what, in real world nothing works S9+ is only a 16months old device..Atleast, 3 saal tak to sab sahi chalna chahieye.. waise hi S10+ k case me 6 month me hi reality saamne hai..When I bought it on the 10th of march, everything was smooth and exceptional..charging time was crazy fast and its been only 6 months and story is over..
