Do portable charges prioritize iphones charging speed over androids?
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 link 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?

AFAIK, Xiaomi chargers offer more current over voltage (which is locked to 5V). Other Android phones may charge even faster than Xiaomis and iPhones, provided the charger implements modern standards with variable voltage.
Charging voltages are no longer limited to 5v and haven't been for a few years. To make things worse there are different fast charging protocols and compatibility is not guaranted. The only real way to measure power throughput is an inline charge meter that can handle voltages over 5v. Modern charging can be very misleading because percentages are not always as useful as we think they are, percent is merely how far between shutoff voltage and top voltage but the curent throughput is not linear during the charge cycle. I'm not a fan of charge speeds over 15w because of how it impacts battery longevity.
