    So, I'm fairly new to wireless charging and definitely new to the new Adaptive Charging. Anyone know if a Qi charging pad is even capable of using the Adaptive Charger to its full potential? Normally when I plug in the cable, a notification says it's fast charging, but I got the wireless charging cover today and when I put it on the charging pad (using the same cable and adapter), there is no notification. So, I'm guessing it's not using the adaptive charging?

    No, I don't believe it's possible through wireless charging. Since wireless charging uses induction you end up with a lot more heat generated even at normal charging speeds, I don't think it would be safe for fast charging.

    My understanding is that the adaptive fast chargers change the voltage to achieve the higher charge rate. This is something new so its impossible for existing wireless chargers to support it. Whether or not wireless charging standards change to support it is anyone's guess.

    Ok, so wireless charging follows a standard put out by Wireless Power Consortium – creating a standard for wireless charging Much like USB, HDMI or BlueTooth, the attempt is to make something that is cross platform compatible. The standard usually follows a power rate of 5 Watts. Since the formula for Watts is equal to Volts times Amps, That means that any QI standard charging transmitter and receiver should not be more than 1 amp. Most I have seen are rated at 650 milliamps (0.65 Amps) or so. The charging cover may have that current rating marked on it. Texas Instruments appears to have come up with something to operate at 10 Watts and will be backwards compatible with QI. Your adaptive charger operates at 9 volts at 1.67 Amps or 5 volts at 2 Amps. I would be surprised if using your adaptive charger with a QI pad would give you anything but QI standard of 1 Amp. The TI QI article is below.

    Does the wireless charging back plate make the note 4 any bigger?

    I am using the Samsung Qi wireless charging back with the older S4 charging plate which is a 2A output. While it doesn't charge using the Adaptive Fast Charging feature it does charge faster than any other Qi charger I have tried.

    It does make the phone a little bit thicker, yeah. It doesn't bother me, personally. It actually helps me grip the phone a little more securely. And the other plus is that the heart rate sensor is kind of indented which makes it easier to find. And the camera lens doesn't stick out either.

    You can always purchase a wireless charging transmitter pad and receiver from eBay - they're relatively cheap and don't affect the phone size in any way. I paid about $17 for the pad and receiver and it works great. It uses the same protocol that the official Samsung back does, so charging is no different. The receiver fits between the standard phone back and the battery - it's paper-thin. You can still charge with the USB port with the quick charger or with any standard charger.

    Wireless charging is definitely slower than with most USB charging scenarios, but, if you charge overnight, it really doesn't make much difference.

    Here are some links: http://www.ebay.com/sch/i.html?_odkw=note+4+wireless+charging&_from=R40&_osacat=0&_from=R40&_trksid=p2045573.m570.l1313.TR1.TRC0.A0.H0.X%22note+4%22+wireless+charging&_nkw=%22note+4%22+wireless+charging&_sacat=0

    Thanks. How does the receiver attach? Does it inhibit swapping batteries?

    The receiver just makes contact with the contacts in the phone - you can change batteries with no problem.

    The wireless charging is probably somewhere around 3-4w,at least it was on my note 3. The adaptive charging is 15w. You can use the adaptive charger but you won't get faster wireless charging

    Tthe Samsung Wireless Charging back cover adds about 0.6mm of thickness to the phone and many hard cases will not fit.

    Yes, the stock Samsung Note 4 case back fits fine. The receiver is about the thickness of 2 or 3 sheets of paper.

    I just put the Samsung back on and my cases will not fit either. Are there any cases available for the Samsung wireless charging back? Surely there must be one case somewhere!

    If you get the little recharging module I would think most cases would still fit on. I kind of modified my Note 2 case so it was flat. Haven't got my Note 4 charging module but it is stated to be Thickness: 0.6mm(minimum)-1.5mm(maximum)..

    Keep in mind many of those pads will block or affect NFC. For my old S4, I used them without issue but had to find the right one. For the N4, I just went with the S-View Wireless Charging Back.

    The official Samsung case off Samsung website, there's the charcoal/black 1 and a bright blue/black one. However, it bowed it out of shape towards the middle, so I removed the back and just ordered the super thin one from eBay. Taking the cover back in a few minutes.

    Could you post a link to the case, please. Or a model number? It looks good! I am assuming it is the official wireless charging back and not a wireless receiver attached to the battery that are available.
    Thanks.

    Is it bulging on the back, towards the middle and pulling the front sides (long sides) away? Ya know like spreading the case apart? That was the problem with my cases.
