Be careful what charger you use with the HTC 10...

[ugxvibe]

I blame the jerk who invented USB-C.

I am not so ignorant to think that HTC is not at fault here. Of course I would like to think they did something innovative here, but not at the cost of safety.

So with this new USB standard there is no provision for fast charging at all? Or just the proprietary Quick Charge? That would seem counterproductive in this age of battery/charging technology.

It has fast charging that works in much the same way, just within safe limits. The Nexus phones and Pixel C all benefit from fast charging, just not the Qualcomm Quick Charge. As I said earlier, the HTC 10 with QC will charge at its fastest approximately 36 seconds faster than an a USB C fast charging, over a 30 minute charge. So following the standard has 98%+ the benefits and 0% of the risks.

This may sound a bit ignorant, and I am an HTC fanboy.. but is the fact that the Pixel charger being 60 watts not the main cause of concern here? I would bet that with such a high output the software in the 10 is not designed to even look at such a high number to manage the amount of power coming through to give the warning about incompatible charger. Would not a software update to let the phone know a nuclear powered charge is connected and to cease charging immediately?

I understand all the USB C shortcuts that have been discussed but I would think that a software update would prevent anything like this from happening regardless. And what is the criteria for the 10 to determine an incompatible charger in the first place?

The stock pixel c charger is 15w. This is the same rating as the usb c 6p charger The stock htc 10 charger is rated at 12.5w on the 5v, and 15w at 9v and 12v. There is also a 60w usb c charger, and it can be used with the Pixel C without any problems. But 60 w isn't standard

I have older micro usb devices that are rated for 5v/500-700ma. I use my 5v/2.4a charger in them without any problems. They only take whatever current they need.

Only htc can tell us what is incompatible as they didn't follow standard

I've read up on this and I think it is safe to say that.
1. QC is not compliant with USB-C
2. The USB consortium wants USB-C to be like a 110 outlet plug; you shouldn't need to care what is on the power end of the usb cord (as long as it is made by a reputable company) it should work and negotiate the power charging rate correctly.
3. Though it isn't compliant QC is faster at charging compared to USB-C, 18W vs 15W. That is until phones support USB-C PD which could theoretically allow 100W.

What I don't think has been 100% proven is just because QC is not compliant it has/will lead to problems.
I understand that both Jerry and Phil had issues, but that is not definitive proof. Qualcomm could still be accurate that it will work without problems even though it isn't compliant with USB-C. I would like to think they know what they are doing and the chip that negotiates charge rate isn't going to negotiate with a higher powered non QC charger incorrectly. If this is not the case though it should be further tested and confirmed.

I vote for AC to potentially sacrifice an HTC-10 by charging it multiple times with a USB-C compliant 60W pixelc in a safe area with a camera pointed on it. It might blow up, but if it does it should generate great traffic from people to watch the video .

I would love to see a side by side schematic of the HTC/Qualcomm setup vs the USB C standard.

The htc 10 supports a maximum of 15.3w through qualcomm quick charge. The 6p supports 15w through non proprietary fast charging. So worth regards to the 10,the gains are minimal (~2%) over the usb c standard implemented in the 6p.

A car thread! Besides, the 10 is more the BMW of phones.

HA! I'll take my 1973 Datsun 240z over your BMW any day. But then I still miss Palm and WebOS and still dislike Leo Apotheker.

Used two Aukey QC 2.0 chargers with Aukey USB Type C Cables over the last 48 hours at home and work plus one Aukey QC 2.0 Car Charger with same Aukey cable and have had zero issues.

Will using a USB cable extender from like 4 years ago with the USB c cord that came with the 10 do harm? I currently have mine set up that way to reach my nightstand but I took my phone off just now to do something and I'm down 4% battery in 6 minutes.

I picked up a 2 pack of Micro USB to Type C from Amazon: http://www.amazon.com/Spigen®-Resis...ag=hawk-future-20&ascsubtag=UUacUvbUpU5187305

So far I've used the OEM charger the phone came with and the Samsung charger from my S7 Edge. No problems up to this point.

I did notice that the HTC 10 seems to suffer from battery drain when connected to the computer with an older USB cable. Although data transfer was more than fast enough for me, the battery did drain while plugged in.

Was it a USB 2.0 or USB 3.0 port? A 2.0 would be very likely to charge at .5A and it's very possible with the screen on and stuff happening that you could be outpacing it while doing file transfers, etc.

I'm somewhat confused why this is all of a sudden such a big deal. Technically, QC 2.0 changed the voltage above 5 V so why is QC 3.0 getting such backlash? I understand it technically falls outside of USB-C standards but the only risk you run is if you use 3rd party cables not rated for QC 3.0, correct? So, you can use QC 3.0 certified chargers to power up your device but also get the benefit of higher transfer speeds cable in USB-C with 3rd party cables.

Again, the risk with QC devices was there with USB type A or B chargers so I am still confused why it is such a big deal with type C chargers. The real question is why does USB-C limit the voltage to within 5% of 5 V when type A and B didn't. If it had a higher range or no range, QC 3.0 would fall within specs and manufacturers of cables and chargers would have to be able to accommodate and test to higher voltages/currents. Regardless, I will still probably get the HTC 10 (waiting for gray on sprint) and just be mindful of 3rd party chargers. I as well as the general public have been doing that for years. The general public goes into the phone store to buy chargers anyway.

I have to say, this is all very confusing. If I use a third party QC 3.0 charger with HTC's OEM cable, am I ok? Also, if I use any non-OEM cable (or adapter for the millions of micro-usb cables I already own) with a standard non-OEM charger that isn't QC 3.0, am I ok? I am assuming yes to both questions, but I don't want to have an issue, especially since I charge my phone overnight on the kitchen counter. If a fire were to start, I'm in trouble.

You're ok if everything you're using is QC 3.0 certified and probably ok if the supply falls under approximately 15W max (9V@1.7A, 5V@3A, etc). To be the most safe, I'd only use HTC's charger and cables intended specifically for the HTC 10.

I figured the original equipment is best, but I would like to have a spare at work, and they're pretty expensive compared to third party chargers/cables. I'm actually getting a free QC 3.0 charger in the mail to test, but I'm nervous.

The phone is designed to use QC 3.0 so that's going to be what's best to use with it, as opposed to anything not QC certified unless the other thing is very weak. The only thing we should avoid for now is a normal USB C certified charger.

Ahhhhhh, ok. No USB-C charger makes sense. Thanks for the info! My older chargers from previous phones actually seem to work quite well, and are very fast on their own.

Well color me confused. I use my Chromebook Pixel (2015) charger to charge my HTC 10 every night. I leave it on there night for up to 7 hours. Phone is always on, cool, and fully charged in the morning.

It's 60 watts:
