One thing to note with the mega fast charging. Is that its semi ‘cheating’ to do it
The only way you can get that is to have TWO SEPARATE batteries inside. So functionally its bypassing the thermal issues of the battery by charging 2 different batteries in parallel. So they havne’t so much invented some new technology that others haven’t figured out.
The issues there is that most OEMs dont wanna bother with complexities as well as the space wasted from having 2 separate batteries in their phones. So don’t really expect this to take off too much
