Default Problem charging from USB Port?

I have a smart phone plugged into the console mounted USB port that I use primarily for GPS & music. When in use like this the phone battery drains slowly. In my other vehicles the phone adds charge when used in this way.

How much power is supplied by the USP port in the console? Is this normal for a 2013 C6?

Cheers,
JB

I may be wrong since i dont have that in mine but As far as I know that port is used to play music thru only, not as a charger. You have to use the 12v outlet in front of the console for charging.

USB port spec is 1/2 amp charging rate. Smart phones typically need 2.0 amps. Look at the charger that came with the phone.

Some lighter plug adapters are available with 2.0 amp output, but you need to read the specs on the adapter. If you buy an adapter with 2 USB ports, sometimes one port is rated 1 amp and the other 2 amps.

I took my 2013 Convertible for a 2 hour drive this morning. Plug the usb into my iPhone 7. My iPhone was 100% charged at the time. The green bar on my iPhone showed it was charging. Drove the full 2 hours listening to my iTunes music library on my iPhone. When I disconnected the Apple usb cord from my iPhone, after the 2 hour drive, it was still 100% charged.

Only a 4" iPhone would stay charged as you use it when plugged in the .5A USB port. My Samsung Note phone can't stay ahead with the 1A port on a 12V charger when using Bluetooth to listen to my music. I have to use the 2A port.

Are we to assume you actually checked to make sure your phone is actually charging? You didn't mention you checked so assuming it is I never had a problem with my Ipod touch staying charged to 100% while playing music in my 13 GS connected to the usb. I have even plugged it in with a low battery warning and it charged up while playing music driving around.

Yes, the phone is getting charged. It just isn't receiving enough power to play music, operate and the GPS, and maintain or add charge to the battery. It drains slightly. The phone appears to consume slightly more power than it is receiving from this USB port. In my other vehicles it operates these apps and adds charge to the battery.

RonC7 above, gives the explanation I expected.

Cheers,
JB

Thank you. Perhaps my use of the GPS and playing music adds additional power consumption to give the results I'm observing.

if you are using your cell phone for navigation and music playing concurrently, it will draw the battery down quicker. I don’t use my iPhone for navigation in either of my vehicles. They both have built in navigation.

I have a strong preference for the modern phone-based GPS like WAZE over the built-in GPS in any of my cars. WAZE communicates with servers collecting information on traffic conditions from thousands of other drivers to automatically route you the fastest way, even around temporary road closures, construction sites, accidents or other delays. It automatically adds new roads without buying a DVD, important in rapidly changing cities. It also warns of police activity, another important feature to me.

Cheers,
JB

It sounds like WAZE is constantly pulling cellular data as well as using the GPS. That will suck your battery down quick. I normally just use Google maps when I'm in a rental. It stores your entire route in the phone so it is only downloaded once.

The C6 NAV is lame when compared to Ford's Sync NAV, but since I don't drive the car that much, or use the NAV that often, it is ok for what it is. I like it because you get the directions on the HUD. No way would I revert to a tiny 5.8" smartphone screen when the NAV has such a large display, and is already in the car. I use to hate it until I learned its limitations and quirky way it works when looking up an address.
