Front USB port charging issue

[jamez74]

Has anyone had any issues with the front dash usb ports charging very slowly?  I notice when I use the front ports the phone charges very slowly but when I use the console or the rear ports it charges fine using the same wire.  I used an app on my phone that is supposed to show charging info, I don't know how accurate it is but these were the results:

 

Wireless: 4.88 watt and 977 mA

Front USB: 4.07 watt and 814 mA

Centre console: 8.14 watt and 1629 mA

Back seat: 12.21 watt and 2443 mA 

 

It shows that the front ports charge slower than the wireless charger.  It's also strange that the charging increases as you go farther back in the truck, you would think it would be the other way around.

 

I brought it in and got the ole "working as intended" spiel.  The tech said he plugged his phone into each port and they charged at the same speed.  Not sure how he actually measured that but whatever.

I have noticed that the front port charges very slowly as well, never gets into "fast" charging.  Which USB port have you tried in the front?  I've only tried the standard USB and not USB-C yet, that is my next step.

Yes, I have the same problem with the usb port. It almost drains the battery of my cell phone rather than charging it. I have a 2020 Chevrolet 2500 FWD Diesel. I even turned the usb-c port over to see if that would change anything. It did not change anything!

This shows me my cell phone Galaxy S20 Ultra 5g is incompatible with my Chevrolet's cell phone charging system. Galaxy

's technical department says the phone is too new to work on the 2020 pickup!
