USB: iPhone Charge Constantly Occurs when connected to USB

I have had that problem too. I swapped out the cable to resolve it. Not sure if there was a problem on the iphone connector end or somewhere in the cable but it was resolved completely for me with a new cable.

Hope that helps!

iPhone model does matter on some models. If its not compatible it can still work but has issues with data transfer.

 

I upgraded to iPhone X so I could use the Q charger! I recommend you do the same.

 

I have this happen on my iPhone with a lot of devices and I'm pretty sure it's because the cable is getting old and dodgy. Try swapping it out with a different one, it may fix your issue.

 

Funny you mention that. It was working fine. Then yesterday I noticed the same issue you mentioned was happening to me. I would pick up my phone and put it back down and it would be fine. I'm going to trend the situation to see how it goes.

 

I had this issue when I was using the USB connection at the same time as I was connected to the car via Bluetooth. There is a mention of this issue in the infotainment manual somewhere. My fix was to not use the USB connection and instead use the 12v. (iPhone 6S)

 

I don't know if it works better with the iPhone X, but for my Android phone, the Qi charger in the Prime mainly serves to make the phone as hot as <you know what>, and dribble in a little charge.

 

This happened with me too. Use this specific cable to fix it: Anker Powerline+

This was mentioned in another thread and it fixed it for me.

 

I want to say if it flashes there are ways to discern what the issue is. Make sure there is no other metal objects under or near the Qi charger in the nook Im saying. It sucks the only available space for some people is that Qi nook and if have change and stuff in there it will mess it up or heat metal since it acts on inductive charge.

 

SYSTEM DESCRIPTION
WIRELESS CHARGER FUNCTION OUTLINE

(a) The wireless charging system enables Qi-compatible* rechargeable devices, such as a cellular phone, to be recharged by merely placing it on the charging area of the mobile wireless charger cradle assembly.

HINT:

*: Qi (pronounced chee) is a wireless technology which allows devices to recharge without using any wires.

(b) Qi-compatible devices which do not fit within the charging area cannot be used. If a Qi-compatible device does not operate normally, refer to the owner's manual of the device.

(c) Qi-compatible rechargeable devices can be charged.

HINT:

• "Qi" and "Qi" logo are trademarks of the Wireless Power Consortium (WPC).
• Although the wireless charging system meets Qi standards, compatibility with all Qi-compatible devices is not guaranteed.

CHARGING INDICATOR STATUS

CONDITION

COLOR

*1: Some mobile devices, cases or accessories may not cause the indicator (green) to illuminate when charging is complete, even though they are Qi-compatible. Check the mobile device to confirm the charge status.
*2: If the charging suspension signal is received for less than 4.5 seconds, the indicator light (green) will remain illuminated for 4.5 seconds.

*3: Refer to the following diagram for details about the indicator blinking patterns.

Off

-

Wireless charging system is turned off

On

Green

• Wireless charging system is on (stand-by)
• Charging is complete*1

On

Amber

• A rechargeable device is placed on the charging area
• A rechargeable device is being charged

On

(For 4.5 sec)*2

Green

Charging is stopped temporarily due to a charging suspension signal being received from the smart entry and start system

Blinks

(Pattern 1)*3

Amber

An open in the charging suspension signal circuit is detected

Blinks

(Pattern 2)*3

Amber

The charging frequency is being changed

Blinks

(Pattern 3)*3

Amber

• Foreign matter exists between the rechargeable device and the charging area
• A gap exists between the rechargeable device and the charging area
• The rechargeable device is not placed correctly on the charging area
• The rechargeable device has been moved from the position where it was first placed

Blinks

(Pattern 4)*3

Amber

The temperature of the mobile wireless charger cradle assembly is abnormally high


RESUMPTION OF CHARGING

(a) After charging is complete, if the rechargeable device is left in the same position on the charging area, charging will resume after 30 minutes elapse.

(b) Charging will resume if the rechargeable device is moved or repositioned within the charging area, or replaced with another rechargeable device within 30 minutes of charging being completed.

(c) If the rechargeable device is moved while it is being charged, charging will resume when the device is placed on the charging area.

HINT:

If charging is stopped and resumed repeatedly due to the rechargeable device being moved or a communication error between the wireless charging system and rechargeable device, charging will be prohibited after a certain number of times to protect the rechargeable device.

SUSPENSION OF CHARGING DUE TO VERIFICATION OF ELECTRICAL KEY TRANSMITTER SUB-ASSEMBLY

(a) The wireless charging system uses the same radio wave frequency that is used to perform verification of the electrical key transmitter sub-assembly. Therefore, when the electrical key transmitter sub-assembly verification is being performed, the certification ECU (smart key ECU assembly) sends a charging suspension signal to the wireless charging system to suspend charging.

HINT:

• When charging is suspended due to the charging suspension signal, the indicator (green) will illuminate.
• If there is an open in the charging suspension signal circuit, the indicator (amber) will blink (pattern 1).

(b) The certification ECU (smart key ECU assembly) sends the charging suspension signal when any of the following conditions is met:

• A door is opened and closed.
• The back door opener switch is pressed.
• The back door is closed.
• The hybrid control system is started.
• An electrical key transmitter sub-assembly is not detected in the cabin.

CHARGING FREQUENCY SWITCHING FUNCTION

(a) If noise is generated in the AM radio during charging, turn the wireless charging system off and check if the noise is reduced. If the noise is reduced, press and hold the mobile wireless charging switch for approximately 2 seconds to change the charging frequency and reduce the noise.

HINT:

When the charging frequency is being changed, the indicator (amber) blinks (pattern 2).

 

I have the same problem only it cycles on-off about every second. My dealer replaced the USB port and I am still having the same problem. I have a USB adapter plugged into the receptacle next to the USB port and it works using the same cord.
