5x "charging rapidly" surprise

[findmyphone]

I've got this Quirky Converge Docking Station for USB charging devices which is USB-A, and I picked up some USB-A to USB-C cables from Cable Matters when I bought my 5x. Guess what...when I plugged the 5x in to this thing, it says "Charging rapidly" on the 5x. I thought rapid charging supposed to happen with a USB-C cables. Not that I'm complaining...

Re: 5x Fast Charging Surprise!

The issue is that the power adapter and/or the cable might not be able to give the power the device is requesting, resulting in fried products. As long as the cables and chargers are quality you should be fine but if one isnt, bad things happen.

well i dont have enough posts to give you the links so.... check out the article at androidauthority.com called usb-type-c-and-3-1-explained

also check out Benson Leung's google plus page for all that you could need about usb c

Re: 5x Fast Charging Surprise!

here is a quick answer from Benson's page
Q : Why is a bad 3A resistor a problem?
A: 3A is bad because all of these cables and adapters are legacy host port adapter cable, meaning the other end of the cable is Type-A plug. The Type-A port and the vast majority of the devices that have Type-A ports were never designed to support 3A charging.

The cable lies to the phone by telling the phone it's attached to a pure 3A charging path, like the C-to-C cable to the OEM 3A charger that ships with the Nexus 6P/5X. The phone will attempt to draw 3A, but that may damage the weaker device you have the Type-A end of the cable plugged into.

Re: 5x Fast Charging Surprise!

Ok, so maybe I should be complaining. Does this mean these cables are bad?

Oh, and as far as the Quirky charger goes...never let your girlfriend purchase tech devices without asking you to research the product first.

Re: 5x Fast Charging surprise

You can get the "charging rapidly" message with QC components, but that's still not as fast as the OEM 3W USB-c charger.

Re: 5x Fast Charging surprise

This Quirky thing definitely isn't a QC-approved component. I do have a couple of Tronsmart QC 2.0 chargers and they don't report "charging rapidly" with the same cable. I did test the cables via adb shell while plugged in to my PC and they appear to be ok, yielding the "0" response. However, I'm not clear how I would test them connected to the charger that's reporting "charging rapidly." Or is the test only on the cable itself, and the charger doesn't matter?

Instuctions on testing cables: https://plus.google.com/+GeoffHoff/posts/eMsr1cyw75s
Possible values
0 - standard USB charging
1500 - 1.5 amp type C charging
3000 - 3 amp type C charging

In my experience any charger that delivers 2 amps or greater will show as Charging Rapidly. Anything between 1.5 and 2 amps will show as "Charging", and anything less than 1.5 amps shows as " Charging Slowly ".

The only cables I use are the Type C - Type C cables that Google sells. I also have a Google Type A - Type C cable, and 2 Monoprice ones as well.

I had cable sticker shock and there were many positive reviews of these cables. Thanks for the info.

What I'm still not sure of if it is safe to use a) the charger and b) the cable. Obviously, something is amiss somewhere but if the phone isn't going to be harmed by using that charger than ok by me.

USB-C is just a form factor for a USB 3 connector, which also works over USB-A connectors So, if your charging device can negotiate the power, it will rapid charge your phone. For example, my Macbooks can rapid charge my 5X.

 

[findmyphone]

So a macbook can rapid charge a 5x but a QC 2.0 charger can't? How weird is that?

The "charging rapidly" mystery continues. I'm only seeing the message with a particular cable and I don't see it with a Micro USB cable with USB-C adapter nor do I see it with a cable from the same manufacturer but different length. The cables are different in legth and also in the connector: the questionable one has a single gold connector, while the others are two welded pieces. I'm also seeing the phone's battery seemingly discharge pretty quickly, though I just removed Facebook app from the phone to see if that's a culprit. Wondering if one night of bad charge killed the battery.

Get the Ampere app from the play store and actually measure the charge rates. With third party cables and chargers, I found that they all don't work well with each other.

Thanks for the link. This whole USB C charging thing keeps getting more interesting...

Using a USB 2.0 to USB C cable last night which is plugged in to a Tronsmart QC 2.0 certified charger, and my 5X was showing "Charging Quickly." And this time, I think it was charging quickly because it only took about an hour to go from %10 to full charge.
