connect off mobile-wire-ammeter-charging
Well, what is this crap? Where it is shown the full potential of charging? Where did you get that off, the phone needs to suck from the charging current?
Test resistive load, and even better on a normal dummy load. Then we can talk about the charger.
What test are the results.
The charge current is determined by the charge controller of phone. Generally a slow charge better for the battery, you'll live longer.
If you need a quick charge, then take the phone with quick charge and charger for it. They know how to bully naprugu and pour good currents in the phone. Well, the cable is normal use, not 3 hairs.
