Hi,
I was wondering if using a 2A charger with a normal Micro USB cable will charge my Note 3 as fast as the same charger with a Micro USB 3.0 cable?
Considering that USB 3.0 only delivers a higher output compared to 2.0 when plugged into a PC, I guess it makes no difference when using wall chargers?
Am I right ?
Thanks in advance,
Ben
USB from a PC will always be less than a dedicated charger whether it is usb 2 or 3. A 2 amp charger is what I use but also pay attention to the lead as some are far better at handling higher currents than others as I found out trying various leads whilst running the app at https://play.google.com/store/apps...=organic&utm_term=galaxy+charging+current+apk

The phone detects if you are using a wall or usb charger, the second is considerably slower. Some usb chargers cheat to seem wall chargers so charges much faster.
What if I use a micro USB cable that is attached to a wall adapter plug, will it still charge fast on note 3?

Charging is not depend on USB 3.0 or 2.0, it acts differently only while transferring data. Otehrwise for charging both works similar.
The stock wall adapter has 2Amp output and I’ve a power bank with same output and the Power Bank provided with a short USB 2.0 cable and with both it takes same time to full charge. So no issues with the cable.
So we just upgraded to Note 3 from our galaxy 3 (wife and I)...
I noticed the charger is a 2 amp charger compared to the SGS 3's 1 amp.
I started reading some threads here and found out the USB 3.0 cable will not charge the phone faster unless it's plugged into the computer.
Apparently the PCM also limits the phone to charging at 900ma. (not verified)
so I'm curious now.... at what amps does this phone charge? I'm trying to get a spare charger to keep in the car, and also trying to get a usb car charger if I can benefit from the 2.1 amp one instead of the 1 amp one that's in there now....
Can anyone tell me if I should get a 2.1amp charger or stick with 1 amp chargers as the spares if it'll still charge at 900ma?
I'm using USB 2.0 cables btw. (unless I can charge faster with the USB 3.0 when plugged to a car charger or the wall, which I apparently won't from my research here)
While I await for responses, I will plug the charger into my voltage/amp reader and we'll see how much power is being drawn, which might give an idea as to how many ma it's charging at.
For whoever that wants to know this information, these are my findings from my meter that is able to measure how much power is being drawn (kill a watt P3)
with the stock charger and USB 2.0 cable (3.0 made no difference) the phone will charge at 900ma with the screen on. If the phone is shut off, or screen is off, it goes to 1500ma. Very steady at those.
with the SGS3 charger that I had, it's a constant 900ma whether screen is on or off... (1.0 amp charger)
now I guess I will have to see if this is the case with any 2.1 amp charger, or if it's specific to samsung's charger with snapdragon's quick charge feature. I believe only certain chargers allow use of this.
I don't know, I'm getting 1800mA by using stock wall charger with USB3 cable and 450 with USB2 cable. I know GS3 would charge at faster rate when using original Samsung wall charger and cable, which had data lines shorted, not sure if it's the same with Note3.
I don't remember for sure, but I think charging rate from computer was pretty much the same 450mA regardless of USB3 or USB2 port or cable. I remember this because I was surprised they didn't take advantage of higher power ratings with USB3, but maybe it was just my particular setup. I used application that shows charging rate, so all is with phone on, but it makes perfect sense, about 2 hours from 0 to 100% charge, if you allow some extra time for trickle charge at the end, losses and usage.

You can't compare that app to a meter that shows you the actual current being drawn

why not? How do you think your meter is working? Phone has similar IC. How did you come up with your numbers first of all? I thought you plug Kill a watt into outlet and it shows what the charger is using at 110v and at about 10 watts(or is it 220-240v for your location), your unit maybe at the limit of accuracy, since the amperage would be somewhere around 100mA, where your device is designed more for larger power consumption like fridge or TV running 300-1000watts and few amps. Is your unit somehow capable of measuring what the charger is outputting and if so, how?
BTW you can't get more than 900mA from PC even over USB3, thats the max limit.
I checked again: galaxy S3 wall charger is giving me 600mA, Note3 charger with USB2 cable gives me 1200mA and Note 3 charger with USB3 cable pumps out 1800mA, computer USB gives 450mA regardless of computer port, but there is something wrong with the USB3 cable that I got, is not connecting properly and I have to wiggle it to connect so maybe bad cable is the reason I don't get higher charge rate from PC USB3.
Any one Disappointed with the charger they included with the Pure. The non removable cord just sucks and a poor choice in my opinion
I'm more disappointed at the size of the wall wart. They could have made more friendly to other power strip users.

Pretty sure they did that so you couldn't just stick any usb charging cord in their...it'd most likely fry it.
The disappointing part is the my other cords not working with Android auto. Luckily I have a nexus 6, and the cord with its charger works.

I guess that could be a reason but highly doubt anything would be fried. Ive been using a nexus 6 turbo charger and before that i was using a note 4 charger to charge multiple android/apple devices without issue. This just limits what i can charge on a single charger now need a second lol

If you plugged in a charging cord that can't handle the increased power it sure could fry the cord. I feel ya though...it would be nice if it were a USB cord.
I'm glad it looks different.... My son knows NOT to plug his HTC M7 into this charger.
I can see if this was someones first Android, the lack of a micro-USB for data would be frustrating, but I have about 5 of these in my desk drawer and throughout my house and office, so it doesn't bother me.
Also having a fixed cord means you don't pulg some 'slow' cable in and not get any benefits. Out my 8-10 micro USB cables, only 2-3 get a decent charge speed.

If a device that does not do Turbo Charging is connected, the charger should automatically adjust and charge it at regular speed. At least, that's what it is supposed to do. The Turbo Charger is supposed to be the single charger for all types.

I think the reason they made the cable fixed is because a lot of cheaper usb cables use very thin wire gauges. Since this charger puts out a lot of current at varying voltages, it's very possible for a thin cable to overheat easier and catch on fire. And my guess is, they didn't want to take any chances
How do we determine if turbo charger is ongoing? I mean are there any indication? Coz when I plug in the TurboCharger that comes with it, sometimes TurboPower Connected shows at the bottom of the screen, sometimes not. Then when I check it on the Status, it says Charging over USB, not Charging over AC? Could be that my unit is defective? perhaps the charger? or the battery?

I've got the same issue going on. My replacement from Amazon will be here Tuesday so I'll have time to mess with both and see if its the charger or what. Currently my turbocharging is hit or miss.

I have this issue sometimes to. So if I need to know if im charging at turbo I use an app from the app store to see if states I'm turbo Charging or not. In the Charging screen it will say "normal or Turbo"

You can use a USB voltage/current indicator device to see it directly. I use one that displays voltage and current simultaneously, it cost about $10 on Amazon.
The Qualcomm QC 2.0 (which Motorola terms "TurboPower) spec is 5, 9, 12, and 20 volts, with up to 2 amps plus at each voltage. The QC 2.0 chargers I've tested including the Motorola charger included with the XT1575, range up to 9V and about 2+ A at 9V, with the higher voltage/amperage when battery is discharged to a lower SoC.. Haven't seen 12V or 20V, I think those only come into play when battery is discharged to nearly zero SoC.
Agree the reason the included charger has cable attached may be to ensure adequate wire gage. Too-thin wire will increase voltage drop across cable thus lengthening charge time in higher power modes. But the design here uses higher voltage to keep current down around the same 2A max current of USB 2.0 chargers, so cable heat will not be a problem with any old USB cable.
I will attest to the benefit of QC 2.0. I thought it was a useless gimmick until I started using it. It does effectively compensate for mediocre battery capacity.
My "Turbo Charging" icon displays properly, but doesn't charge very quickly if connected to a cheap extension cord.
Plugged into the wall, the charging Stull doesn't impress me that much

It's defective. Call moto they will replace it for free. Just have to send copy of purchase receipt. Had the same issue.
The charge rate depends on how discharged the battery is when connected to charge.
More discharged (lower SoC, State of Charge) will drive a higher charge rate.
As to the difference between this Motorola TurboPower (aka Qualcomm Quick Charge 2.0), vs. other phones:
I've measured up to 1.4 amps at 5V nominal on other phones, that is about 9 watts charging power. That is max charge rate, with a very discharged battery. As the battery charges up closer to fully charged, the charge rate (power) is reduced. Total charging time from fully discharged to fully charged would be about 4-5 hours, give or take, for a typical cellphone battery.
For comparison, the QC 2.0 measurements I made with the MXPE: Up to 2.2 amps at 9V nominal with a phone battery discharged to about 40-50%. That works out to about 20 watts charging power. As with other Li-Ion battery charging systems, this also declines as the battery approaches fully charged. Total time to charge, from fully discharged to fully charged will be about 2-3 hours, give or take.
So the marketing claims about QC 2.0 are about right: A 75% improvement over conventional charging systems.
The biggest gains come when charging batteries discharged to lower SoC. If you are comparing charge rate/time of batteries discharged to only, say, 70-80%, you will not see as much of a difference with QC 2.0.
I'm not a QC 2.0 marketing shill, mind you. I pretty much ignored it, before buying the phone. But for this phone, QC 2.0 actually does a good job to compensate for the mediocre battery. I can run the battery down to 40-50%, put it on QC 2.0 charger in my car for my 30 minute commute, and it is charged to around 80+% when I arrive at my destination. There are a lot of QC 2.0 certified aftermarket chargers out there too, Qualcomm did a lot of work on the front end as part of bringing it to market. (Just make sure any AC charger is UL listed or equivalent, if you care about safety.
Caveats on cables: The cable does make a difference at higher charge rates. Thinner gage wire will impose a greater voltage drop at higher current, this will reduce power and thus increase charge time.
Typical USB cables are AWG 26-28. You can buy 20, 22, and 24 AWG USB cables. Some cables advertise heavier (22-24) gage wire for the power leads with standard (26-28) gage wire for the data leads. The aftermarket QC 2.0 AC chargers I bought listed their included cables as 20 gage.
Get the heavier gage if you want full QC 2.0 charging.

Just to check did you use S6 original charger ? And does it charge same with the turbo power charger provided by moto?

I just want to make sure I understand this correctly. The Nexus 6P doesn't have any type of fast charging built in to it. The phone will charge faster using a USB C to USB C cable because that type of cable is capable of delivering more charge to the phone. So essentially, as long as the cable is USB C at both ends, I should be able to rapid charge the phone using any USB C wall adapter or power and right?
The new wall adapter will have to have the same specifications as the original one. It's not only the cable, obviously.

See HERE. Obviously, select the 6P.
Be sure to read the notes at the bottom for exact specifications required.
Mine rapid charges in the car with an old iPad 2.1A rated usb charger. It doesn't actually say fast charging, but it gives a charge time estimate and it's definitely fast. Can go from 65 to full in a 25 minute drive. Amazing.
I use a USB adapter in the car and get "charging fast"

OK.... so i wanna know is it bad if i charge this phone with samsung adaptive charger ? and what about AUKEY USB-C Car Charger with 5V/3A USB C & Quick Charge 3.0?
My another problem is when i use oem charger my phone getting really hot like the back panel 110 degrees till almost 90% and then start cooling down, but i dont have this problem with samsung charger and my phone still charge pretty quick.
is anyone has the same situation?
The phone uses USB-C power delivery for charge spec. QC3 chargers don't work at all on my PH-1, seriously charges at .5amps. You're fine to use the Samsung charger or any other adaptive charger like Ankar power port chargers, they work fine.
Not sure about your phone getting hot using the stock charger though, mine doesn't do that.

I've read that some peoples phones charge slower than it uses power when using older chargers, but then some people say they charge ok, slower, but not that slow.

Yeah the power port chargers work just fine. Just not QC3 chargers, in my experience.
