My xiaomi portable fast charger clearly charges my girlfriend’s iPhone faster than my high end android device. Doesn’t matter which port, which cable or which android phone. It starts by charging fast but as soon as I plug her phone the fast charging speeds go straight to hers and mine just chargers very very slowly.
I’ve got the impression that this may be on purpose or at least has some clear explanation.
Any thoughts?
A potentially great way to destroy your GF’s iPhone, iPhones start fast charging at I think 20W, the Chinese phones are like 45+ Some are even higher. Fast charging happens different ways, some hardware, some software, some a mix. Wrong charger with wrong phone can do serious damage. Not all internal circuitry will down volt what’s coming in.
