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?
Does the charger display how quickly it is charging? I assume her iPhone’s battery might just have a lower capacity as iPhone usually have smaller batteries than comparable Android devices.
A good way to check would be to download an app that measures battery charge/discharge rate.
What app do you recommend? I use accubattery. Is there something more simpler.
I think the one I used is called Ampere. Pretty straightforward, just shows basic info like charge/discharge rate, temp, battery type, and a few other things.
