    Default Quick Charge 2.0

    I'm surprised there is not more talk about this. I suppose it's because the phone did not ship with a 2.0 charger. However, I bought one on Amazon and Wow is it amazingly fast!!

    I didn't know they began selling them. Roughly how much faster would you say it charged, or have you not compared them?

    HTC hasn't released them yet, but you can use any 2a wall charger and the phone will charge with quickcharge 2.0

    Can you affirm whether the block or USB portion is what makes the charger quickcharge 2.0 compatible?

    The M8 supports Quick Charge 2.0, it's a combination of the processor chip and charger that makes it work.

    It's the processor that chooses either quickcharge 1.0 or 2.0. You have to have a wall unit that outputs at 2a and your processor will enable the quickcharge. You might need a specific cable too, but I can't confirm this

    I have a 2 amp charger in my car and at home. The difference in charging speed while notcible isn't as fast as I thought.

    Anyone have a link to the product (Amazon or otherwise)?

    How much faster is it really? I mean, the battery life is already really good on this thing, but a quicker charge would serve me well.

    Thanks! I understand the processor is capable. Just curious about the accessories part because I need a new car charger and just want to ensure if I'm spending money it's on a setup that will provide quickcharge 2.0. I my opinion it will be most beneficial in a 10-20 min car ride when I will not be using my phone anyways.

    Actually I believe the output 1.5A or 2A supports quickcharge 1.0 but the actual wall charger has to have quick charge "2.0" compatibility so that both the chip inside the phone and the chip inside the charger know to use "2.0" as the charging speed. The amps a charger outputs doesn't have to do with the quick charge technology. For example a phone that has 800 chip or higher will charge in "1.0" mode regardless of what amps the charger is because to charge in "1.0" only the phone chip is needed but for the phone to charge in "2.0" mode the phone and charger have to have the "2.0" mode compatibility chips inside of them.

    According to this press release:
    ...detects commands from a Quick Charge 2.0-enabled device, and adjusts the output voltage of the AC-DC wall charger to deliver increased power to the devices battery through a standard USB cable
    So, looks like the trick is increasing wattage by raising the voltage beyond the 5.0 USB standard. This is reasonable, as going beyond 2 Amps is pretty harsh on those tiny USB cables. That same article says that their reference chip can output 5, 9 and 12 volts at max 2 Amps. 12x2=24 watts. This is nice.

    Moreover, this other press release says that the standard supports up to 60 watts. This is pretty awesome. This means raising the voltage to 30V if you wanna stay at 2 Amps, or 20V if you raise it up to 3 Amps. I don't think they would dare to use 15V/4A - that would be too much current for the tiny cables.

    Here it says about wall chargers to be released in early 2014. However, where I really need speed charging is in my car. I cannot find anything about car adapters.

    Wikipedia says usb 2.0 cables have a maximum current of 1.5 amp, how is it possible to pull 3 amp? Does the HTC rapid Charger or the Motorola turbo Charger come with special cables?
    I bought the Incipio quick charge 2.0 car charger and it didn't come with a cable so I have no idea if I have to buy one (and which one to buy) to get the full potential of the technology.

    They don't come with special cables, and they do provide much more rapid charging, so either the analysis above is wrong or the cables can handle much higher amperage.

    Can you please install the App Charging Report and check at which current does your quick-charge 2.0 charger work?
    Thank you

    I have seen some micro USB cables for sale online that are spec'd with larger power cables to handle higher currents. They weren't advertised as QC2.0 compliant, just a more generic heavy duty or higher power capable type description.

    But that's completely not required for the feature.

    There is a lot of philosophy in this thread.
    If you are curious and lucky enough to have one these chargers, the only way to know the thruth is by finding a cheap microUSB cable, cutting it in the middle and using a multimeter to measure voltage (across the two wires and current (passing by one wire). Ask help from a friend if you don't know how to do it.
    The measures should be taken when the charge of the phone is low (15%), medium (50%) and high (85%). If it works as usual you will notice peak power (current or voltage) at 50%. But this system is new, so it would not be scientific to make prior assumptions.
    Be careful and do the test away from flammable objects. A tiny cable might get warm or hot.

    Cutting it in the middle? What are you talking about? All I'm saying is that a SPECIAL cable is not required for QC2.0. A regular (high quality, uncut) USB cable works just fine.

    I just tried the Incipio quick charge 2.0 car charger and the small micro usb cable (charging only) that came with an anker Bluetooth speaker that I bought a month ago and I checked the current with "charging report" app and it was pulling only 1. 3 amp.

    The amperage is completely irrelevant.

    lol. You know everything. The amperage as everything to do with it wise guy
    Check this stats another user posted with his chargers https://picasaweb.google.com/m/viewe...88476764468738

    Edit: I take it back. Seems that app was not measuring correctly. GSam battery shows that the current was much higher https://docs.google.com/file/d/0B3w7...p=docslist_api

    Hey all. I just started trolling here so I don't know much of the technical stuff. But for anyone else like me who was waiting for either their carrier or HTC to roll out one of these (and HTC sure is taking their sweet time) Verizon released theirs for $34.99.

    Totally worth it to me as I've been having battery drain problems. (Verizon replacing so moot at this point.) Gets me about 30% higher battery in maybe 20 minutes. I can get from 30% to almost 100% in about an hour, maybe a little more. My understanding is the processor slows down the rate of charge as you get a higher charge restored to the battery to protect it. Think exponential decay, if you will. Anyway, I recommend. Has made my life a lot easier when I can only drop in quickly in the evening then have to run out the door to the next thing.

    Verizon has a branded charger??

    Yeah, so I can't post links because I haven't posted 10 times yet haha. That's absurd. But just Google "Verizon Wall Charger with Fast Charge Technology for micro USB" and should take you there if you're interested.
