Kalleh - thanks for the information.
My post refers to the program and not the equipment.
Some devices with Android (and not only) during processing - especially large files (hence the need to secure more energy for these processes) to programmatically load limit - and that no matter what the charger (although these are made in china crap ).
Companies that have shown to permit circumvention of these limitations - of course, as usual, "the devil is in the details" - and it can happen that someone can not do it.
In my 2 samsung's and Lenovo - passed the exam.
