Hello experts!
Some weeks ago I byed a Huawei phone G8. With my old Nexus 4, there was a feature that I´m missing. Charging with Qi. At the G8 there is no provision of home because the device has a metal cover and thereby provide the factory can not.
So I tested a universal variant in which the receiver is connect about the Mico USB from the phone. The receiver has a power output of 1000mA and is It is this model: http://www.amazon.de/gp/product/B00C5X1JGE?psc=1&redirect=true&ref_=oh_aui_detailpage_o05_s00
The install was easy, space between Sender and receiver less then 4mm. I have test 2 Models of charger, a Zens like this http://www.amazon.de/gp/product/B00C5X1JGE?psc=1&redirect=true&ref_=oh_aui_detailpage_o05_s00
And this model:
http://www.ebay.at/itm/121797953332?_trksid=p2060353.m1438.l2649&ssPageName=STRK:MEBIDX:IT
With both models, I have the same problem. The charging of the mobile phone works so flawlessly to 95%. Above this threshold, there are only charging interruptions, sometimes stops the charge. I have use different power supply units tried with 5V 1A to 5V 2A no change, always the same problem.
Charging up to 100% is possible with the charger cable without Qi. Does anyone have experience with Qi charging in conjunction with Huawei mobile phones? Can anyone give a hint what I could do to?
I've even ordered a Qi Circuit Board with 3 coils from China. Should obviously have more output line. The model I have not yet, however, is on the way. Gladly I will tell my experience with this model.
Many thanks for your help!
I ask this since it seems more feasible than enabling something like Quick Charge 3/2.X since this method is open and not proprietary.
It also seems feasible since the OnePlus 3 can clearly handle up to 4A of current at 5V (dash charge) so in terms of hardware it should be able to handle 3A at 5V similarly to the Nexus 5X/6P via the standard USB-C spec.
It doesn't even seem to be able to handle 2.4A via a USB-A to USB-C cable, or even via a USB-C charger using a USB-C cable.
Is there some hardware or software limitation I'm perhaps missing? If it's a USB-C device it should be able to charge via the USB-C standard
To my knowledge one plus promised dash source by the end of July. Also to my knowledge is something must be enabled and PCB hardware must enable fast charging. Galaxy s7 doesn't have qc3.0 despite having the correct hardware.

i do understand something needs to be enabled for QC2/3.X but why for USB-C?
Short answer ... no one knows and they're talking out of their ass ...
Long answer - Even if its a hardware/software enabled type feature - most do not know how to program it well enough to incorporate it. So everyone has to rely on source code with it already programmed to include it with any rom. Some guys can program it but dont have the resources and/or phone to do so. The average programmer reading your comments doesnt know specifics which is why you get a lot of "to my knowledge" "as far as I know" "in theory" type statements

Quickcharge is closed and proprietary, it's just the licensing is cheap. It only work on phone that have recent qualcomm SoC. Yes our OP3 have a SD820 but the manufacturer also have to implement it in the phone, with software but also hardware.
It's a shame that Oneplus didn't use Quickcharge because with the price of one Dash Charger or VOOC charger you can buy a 6 port quickcharge 3.0 charger... And quickcharge can use standard cable (if you use another usb C cable than the one provided, the red and blue one, dash charge don't work even with the dash charger)
So I'll tell you one reason why the Oneplus 3 won't support quickcharge even with some hack : charging a lithium battery at a high voltage make it go BOOM!
Quickcharge use 9, 12 or even 20V to make charge faster (and it's an advantage with low quality usb cable). So the phone have to be able to convert 9 or 12V down to 4.2V and it's a hardware matter.
Now for the 5V/3A of the USB-C spec, it's Oneplus that limit it (and it's safer that way). I tested many charger with a voltmeter. I used some charger from 1.8A to 2.4A and it only draw 1.5A. I used a genuine apple charger at 1A (the A1400) and it only draw 0.5A, the same when it's hooked on a computer. With the dash charger and the dash cable, it go up to 3.5A. It's not 4A but it charge pretty fast. With the same charger but with a normal USB-C cable (2.0 and 3.1 i tried) it draw 1.5A.
So the dash cable use some extra pin to make the phone identifying the dash charger and the dash cable, when one is missing, it charges at 1.5A or even 0.5A.
Why Oneplus don't use the full 3A of the USB-C spec? Dash charge/VOOC I guess.

If it's "unsafe" then why would Google use in the Nexus line? If anything, all of the quick charge out of spec systems (like dash charge or quick charge) are "unsafe"

you can have BOTH. why REMOVE USB-C 15W charging?
charging slower is safer than charging at high voltage or intensity, I didn't imply anything else.
If the charger provided can do 5V 3A like the one provided with the Nexus 6P can actually charge at 3A a Oneplus 3, how can you sell a dash charger with a dash cable that do 3.5A (and the VOOC charger that is even more expensive and need a micro usb to USB-C adapter)

Easily? Dash charge is far more quick not to mention heat efficient
Also, slower charging is not safer by default -it's less hot charging that is safer more so,
Dash charge is heat efficient? Yes it will be warmer on a cold day. Like any battery charging slower is better for the battery life.
I don't understand your last sentence, sorry
If you are talking about the efficiency between the power on input and output from the charger, I think that the power is not high enough to really make a difference with a standard charger.
I am still a big fan of Qualcomm quick charge because I could use a 3 meter (10ft maybe) usb cable not even made of thick gauge.

I think what he is getting at is during quick charge the higher voltage results in more heat in the phone, with dash charge the heat is contained in the charger. Thus phone stays cool during charge which is safer for the phone.

Hi everyone!
I have a car charger for my old phone, the OnePlus 3. But yesterday my Samsung Galaxy s8+ arrived and is now my daily driver .
My question is : Does a official OnePlus car charger (with dash charge) works for my Samsung Galaxy s8+? If so, does it damage the battery?
Kind Regards,
Pieter
I have tried mine with the old OnePlus dash charger and though it works, the charge speed is crazy slow. The phone was reporting that from about 40% it would take 5 hours to finish the charge.
Am guessing there is something propitiatory in the dash charger that is causing this. I dont use it on the S8 anymore, incase its damaging the battery somehow.

It won't damage the battery, but it also won't do fast charging as the Dash charging is proprietary and doesn't support Qualcomm's (also proprietary but much more widely used) Quick Charge 2 (or higher; QC is backwards compatible) that the S8/S8+ uses.
According to the car Dash Charger specs the standard (non-Dash) charge supports up to 5V at 2A, which is 10W. Compare this to the official Samsung charger's 9V at 1.67A (QC2), so provides 15W.

In theory then it should be able to charge the S8+ at two-thirds of the speed of the official charger, however it is possible there are other incompatibilities that slows it down - ie. the Dash charger won't provide the full 10W for some reason. A possibility might be the Dash charger cable, as from what I understand this is a bit different to a normal cable to support the Dash charging technology. Maybe try a high-quality standard USB and see if it charges any faster?
An aside: The S8/S8+ is the fact it can also fast charge over (the non-proprietary) USB Type C with 5V at 3A (also 15W). This isn't USB Power Delivery (USB-PD), just the 15W allowed by USB Type C, and since that can provide the full 15W the phone can use over QC2 there's no actual need for USB-PD - but most charges that support 5V at 3A are labelled as providing USB-PD and will work with the phone even if the phone don't use the 'PD' part of the spec.
Guys, I bought this Wireless Charger Pad Slim EP-P1100T, to use on my Note 10 Plus, the information says it has a fast charge, but when I put my device on it, fast charge information does not appear even though it is enabled on the cell phone, is it really so? Android 10 does not show the message?
I think you should use Quick charge 3.0 charging head not the samsung 25w head with it , anyway even if you use the suitable charger with it Note 10 plus automatically shut off fast wireless charging when using slim pad for more that 20% of fast charging because of heat issues since slim charging pads don't have cooling fans and they heat up very quickly
I have one of these also, the only fast charger that enables fast charge with that wireless charger is my old Note 9 charger, it provides the 18w QC2.0 the wireless charger needs.

I'm using the charger that came with Note 10 + ...
Is that why the phone doesn't charge fast charge with the pad?

Yes, this charger was designed for the previous generation of phones (S9, Note9 ect) which included a compatible charger. Samsung confirms this here: https://www.samsung.com/us/mobile/m...nes/wireless-charger-pad-slim-ep-p1100bbegww/
Samsung doesn't use Quick Charge technology since it's a Qualcomm only feature and Samsung uses its own chipset which isn't Snapdragon.
Instead, it uses Power Delivery which is a standard and better in all aspects.

That's not entirely true, Samsung definitely do sell phones with the Qualcomm Snapdragon SOC and the 15W charging on most of their previous phones (S6, S7, S8 and S9 generations) was QC2.0 or QC2.0 compatible. This is why I am able to fast charge my Exynos Note 9 at full 15W with a QC3.0 charger.
USB Power Delivery is good but it's just another charging protocol, later versions of Qualcomm Quick Charge are also USB-PD compatible.

That's right it is, but there's more.
It's not just an other charging protocol, it's an USB standard, that's means all USB ports will have it by default.
Quick charge is proprietary licensed and will be dead soon because there's no use of paying licence for nothing.
And it's not the same at all. Power Delivery is made for dynamically adjusting current intensity and tension depending of the device you plug in and battery level, for them to take only what it needs.
Quick charge isn't, that's why you need dedicated QC ports on chargers.
It's easy for QC to be "compliant" if it shares one similar spec, but it's useless since all next USB ports will use USB-PD.
And that how it worked before, with fast charging, you only had to take in consideration that the output specs and the chargers is equal or higher to the input specs of the battery to get fast charge, but it's risky for the battery.
It may appear silly, but for efficiency and durability, lithium ion battery should not be charged at the same current and intensity at all levels and that's at least one reason why it's important.

Hi all,
Is there a wireless receiver pad out there with QC3.0 capabilities?
Thanks
PS: there are pads available that go in the USB port and add wireless charging to any phone. Watch this video to see what I mean. but I have not been able to find a pad that supports QC3.0. I am just wondering if anyone knows a brand or a certain hack to get fast charging with these pads.
QC3.0 30w wireless chargers are available (for example) but I haven't found any receiver pads marketed for 30w or QC3.0.
now that being said, the laws of electromagnetics tell us assuming the coils don't change if you double the voltage on the transmitter coil the voltage will double on the receiver end (see this). Theoretically increasing the voltage will increase efficiency. but the electronics (voltage regulator) in the pads might prevent the higher voltage from getting to the phone (watch this)

Why would you need one with QC3.0? Qi wireless charging standard doesn't supply enough voltage after AC-DC conversion to meet 9V or even 12V for QC3.0 spec. And even if it's possible, it would be quite inefficient I would imagine.

The reason why 30w QC3.0 wireless charger exists is only because of the higher wattage for devices with high wattage receivers, the charger pad doesn't communicate to the phone with QC3.0. It only communicates QC3.0 with the wall adapter. Plus, QC3.0 does not include wireless charging as a spec requirement. And probably because of the additional circuitry needed to convert higher power, no one want's to make it since it may make the receiver pad bulky.
Yes what you said might be true, but you have to factor in losses in the circuitry generating more heat at both the transmitter and receiver side therefore wasting power. And I suppose coils needs to be wound for higher voltage and lower frequency? Not an expert in electromagnetics.

Unfortunately no, but I doubt you'll find any product that achieves that
it just seems unnecessary to have an external wireless charger, it will never be 30w like high end phones, even with a slow charger you're going to end up spending $50 for a useless feature which is why manufacturers just ditched it until it becomes more affordable to put in midrange give it ~2 years
