[Q] Slow discharge with magnetic charging USB port

I've set up my Z2 as a Sat Nav in my car and using a magnetic USB lead plugged into a 3A charger. I've noticed that the phone doesn't really charge with Google maps running and playing music. It slowly loses the charge. Has anyone come across this?

Have the same issue with mine. I've got a magnetic adapter that I use with my ordinary USB cable and it can't charge the battery when I use waze and Spotify. At night I use a magnetic charger cable and then it's charging fast but not with my adapter.

Mine also charges very slowly or even discharges depending on the usage through magnetic port. My guess its due to cable being ****ty

I'm wondering maybe the cable is not delivering enough current despite my charger can output 3A.

Pretty sure screen on, gps and active sat navigation type app on nearly all android phones will lead to this.

Fact is the device is using lots of power, so much that the charger can't keep up. You also will likely find the phone will struggle with heat issues while doing this.
