Car charger for One M9... how to tell if quick charge?

[n8nagel]

Hi all,

just got in the mail today two car chargers... an Aukey CC-11 and a Choetech C0042 because they were the highest rated ones that looked like they'd work for me on Amazon that came up when I searched for Qualcomm Quick Charge 2.0 car chargers.

Is there a way I can tell if my phone is actually recognizing them as quick charge chargers? When I plug my phone in, either to the special quick charge port, or to another general high-current port, and flip to the "power" menu on my phone, it says "Charging on AC" with no difference at all between the ports. (exact same behavior, all ports, both chargers.)

Is there somewhere else I can look on my phone to tell whether it recognizes a charger as a Quick Charge 2.0 charger?

Or is the only way to tell to go for a long drive with Waze running and see if it keeps the battery topped off or not?

Thanks!

There are a few ways, like measuring the output voltage of the charger while it's charging the phone, but unless someone's written an app to do it, there's no way by tapping icons on the phone. (Quick Charge is a trademark, so it should say so on the chargers. Adaptive Rapid Charge is totally different, and won't do anything special on an HTC.)

OK guess I will have to break out the Fluke and sacrifice a Micro USB cable... really curious about this.

I figured that QC2.0 would throw up *some* sort of notification as it's a really useful/cool feature. Just goes to show you that I'd never make it as a marketing guy. I really hope that one of these works because I really do have a real need to have Waze running for hours at a time without draining my battery. I was using an old Motorola 750 mA charger and my battery will slowly drain; I usually charge overnight and then drive to work in the morning; phone is usually at 99% or 100% when I get in the car, maybe 96% when I get to work, which says to me long road trips will need some topping up afterwards.

Both of the chargers are explicitly marked QC2.0 so hopefully they're good. I'll use the Aukey on tomorrow's commute, I'll try to remember not to plug in my phone at my desk so it'll be good and drained when I leave to come home.

Just remember Quick Charge isn't meant to charge rapidly til power gets to 100%. I believe the Quick Charge certified chargers only use max power when the battery is below 40%. It works that way in order to preserve the overall life of the battery.

For his purposes, that's fine. If the battery keeps charged for 10 hours while he's in the car, it doesn't matter if it drops to 39% before quick charge kicks in and brings it back to 40%. So it'll be hovering around 40% for the whole drive. That's perfectly okay for the battery.

I get what you're saying. The only reason I mentioned it is because some users don't realize that. They plug it in at say 75% and expect it to get to 100% in a few minutes. I've just read a lot of threads with people disappointed in Quick Charge because they expect it to charge rapidly anytime it's plugged in.

I'm following you guys... well I used the Aukey charger on the way to work this morning and it already does better than the old Motorola one (which when I pulled it out I saw that it was rated for 750mA) that I was using previously. What would happen before was that I could get in the car and watch my state of charge actually *drop* while driving even though the phone was plugged in, because I am always using Waze, possibly a few other apps running in the background, etc.

This morning when I left the house the phone was at 96% state of charge; by the time I got on the highway (about 10-15 minutes) it was back up to 100% so even if it isn't "quick charge" it is putting out more current than my old one, which is keeping my phone happy.

Now if only HTC would release a car kit...

Yeah, 750 isn't really enough to keep up with GPS. I even noticed when I was transferring music to my 64GB micro usb via my laptop's usb port it didn't provide enough power. My battery was actually draining a few points even though it was charging.

I believe the current "floor" for charging smartphones is at least 1 full amp, so 750 mA would not be adequate.

I hear you... seems like at least every other time I get a new phone I need to get newer, beefier charging infrastructure to support it. I remember having to buy the Moto charger back in the day because the older one I had at the time (which probably conformed to the USB 500mA standard) had the exact same issue

I know, TANSTAAFL. Would have been nice if HTC had included one with the phone, but whaddayagonnado.

So the Aukey worked fine. Was at 66% when I left work, after about 75 minutes of driving while running Waze it was at 80%. Oddly using the HTC USB cord that came with the phone the phone would stop charging after about 10 min. or so but the one that came with the charger worked fine. I made a stop and then drove for about another 5 minutes without running waze or having the screen on and it was at 85% at the end of the drive. So I will not charge my phone tonight and really test it in the morning. So far so good...

Also gave up and ordered a universal car mount. Guess HTC doesn't care about mobile nav users... which reminds me I need to get YaV1 set up on my phone before my next road trip.

Speaking of Aukey Quick Charge accessories, I picked this up a while ago.

It's a great portable battery bank for only $30. Works well. It's a little thick, but if you're traveling it's a great accessory.

Nice. I'd go for it but I actually got a Mophie for Xmas (before I got my new phone, battery life on my old one, especially in hospitals where I spent way too much time, was abysmal so it was a lifesaver.)

 

[n8nagel]

Well the Aukey charger seems to be good. Let phone run down to below 20% at work yesterday and it charged back to 50% on my way home. It did stop charging several times and I assume that was due to temperature. I'll try the other one over the next few days and hopefully it works as well.

Quick chargers 2.0 must have the logo of a thunder with a circle to be certified as such.
I bought a samsung adaptive fast charger car charger which is in fact quick charger 2.0, I will try it asap

I switched to the Choetech charger a few days ago and it appears to be working well also. I've also started using a "ZiLu" universal mount ($10 from Amazon) and while it's not a car dock it does a fairly admirable job of sticking to the windshield (it has some quasi-sticky backing on the suction cup, like a washable lint roller) and also holding my M9 steady even in landscape mode where it has to be held a little off center due to the silly positioning of the power button... just figured I'd follow up and let you all know.

Thanks!

When I was in the market for a new charger (wall mount and then separate cord that plugged into it), I downloaded the "Battery Monitor" app which shows you by the minute the rate your phone is being charged in mA. You can see the performance by cable and mount that way to verify the charging capabilities of each.

 

[n8nagel]

Cool, thanks for that.

Just stopping back in to let you all know that I ended up driving for about two hours yesterday and was running Waze, streaming music over my data connection, and sending it to my head unit over BT simultaneously. Using the Choetech charger my phone stayed at 100% battery the whole trip, although it did get a little warm. So the Choetech is an acceptable charger it would seem for the M9... I've been using it over the Aukey because I need to carry a different cell for work and sometimes my girlfriend is riding in the car as well and having more than two ports is very handy. I will make an effort to use the Aukey more so I can be more confident that it is good as well but I haven't experienced any problems with either to date (touch wood.)

You should try the "Ampere" app; it supposedly measures live current flow into/out of your phone. It seemed to work just fine for me.
