Will the S8/8+ benefit from using USB C Cables that DO NOT have the resistor when connected to chargers or devices that CAN handle the higher speeds and amps?
For example will it benefit in speed if plugged in on a 10, 20, or 40GBps usb c cord vs one that's turned down with a resistor?
Will it charge faster on a charger that has native USB C and can put out more amps?
The NON resistor cables are a lot more expensive, and I understand it's risky having them around if you (or the KIDS!) accidentally use them between the wrong two ports. So before I order all new cables for all our rooms, cars, etc, I want to know if it's worth it to mess with the faster, higher amp cables or not.

Hey guys, while this information may be redundant to some, this is my first 2A charging phone having come from a GS2. A few note's i thought i'd share about fully utilizing the maximum charging of this phone. Using Elixer app, i was able to determine a few tips when charging
CABLE LENGTH MATTERS
I went out and bought some nice long monoprice cables, 10' and 15', i hated the feeling of being sucked to the nearest wall when you wanted to charge and use your phone. Plugged it into my nice new S4 wall port with a 10' cable, and checked the amperage being sucked in, to my surprise it was no where near the 1900mA max i should be getting. Went to the 15', even lower current (duh, for those who weren't able to put that together), went back to my 6' cable, boom, back up to 1900mA.
TLDR: 6' max for maximum charging
PAY ATTENTION TO 3rd PARTY SPECS
often times these specs are misleading on amazon and such. Often times you will see a 2A car charger with two ports! Awesome, but sadly each port is usually rated for 1A each. This will not be enough to output a full 1.9A (1900mA) for your device. You need to look for 3.1A rated two port items (2.1A and 1A port), or 2/2.1A output for single port chargers, or for true dual charging, a 4.2A rated with each port rated for 2.1A. They do exist.
Also, pay attention to whether the device is iPAD (or any dumb iDevice) certified or marketed to the iCommunitiy. Often times even though the dual port chargers with the 2.1 and a 1 amp port, the 2.1 amp port does NOT have the correct data ports shorted out. What this means is how the phone detects the power source. When you hook your phone up to a computer, there are channels in the USB cable that tell the phone it will be using data, this then limits the amount of power it will draw. The iPAD chargers are set up this way where the data ports are not shorted out, so your phone will not suck the full amount of power. To bypass this, you either need 'CHARGING ONLY' USB cables, which short out this channel for you, or you need to mod the charger with some light soldering. Often times i find this iPAD issue on the ones rated for 2.1A, the 2A chargers generally do not have this issue (just a generalization on the marketing of the chargers, not a fact)
do some reading on the spec's before you blast the product, i hate it when people bash it when they buy the wrong thing and it's their own fault for not taking the time to research it. And if it's not clear, don't buy it!
Ok, that's all i have for now, hopefully this helped some people out there. make sure you do your reading before you write up posts about your phone charging slow, or bash a product you bought because you didnt understand what it was truly designed for.
Hey all,
I've been using my N10 for a week now and am wondering why and if it's normal for the tablet to require 8+ hours to recharge?
I'm plugging it into the wall using a generic USB cable and non-Samsung power block. Should that matter at all?
Signed 'confused...'
Yes, the charger matters. The stock wall charger is at 2Amps, while a normal USB connection is at 0.5Amps, for example. All devices will charge more slowly on lower amperages, but since the battery of the Nexus 10 is so huge (9000mAh - about double your average laptop), charging it from 0 to 100 will be dreadfully slow, if you're not using a proper charger.
1. Are there other wall chargers with higher Amp output that are safe to use w/ the N10?
2. Is there any long term damage to the battery using a higher or lower Amp charger?
Another issue is if the charger is made for an Apple product it doesn't short the data pins so the Nexus doesn't see it as a high amperage power supply and only pulls .5 amps.
Use the OEM Samsung charger or get one of these:

And if you want a it to charge even faster, use a pogo cable.

Higher than 2.1 amps? Not commercially that I'm aware of, though you could always jerry rig some contraption to deliver more.
The problem is, however, that the device will not draw the extra power. A device will draw the power it can use, and no more. I haven't tested what the draw is on my Nexus 10, but on my Note 2, it never draws more than 1.8 amps (although that reading may be a little inflated and it really only draws 1.5 amps). I suspect it's more or less the same with the N10 and the stock USB cable and Samsung 2.0 amp charger. So if you went nuts and jerry rigged a 50 amp power supply to the device, it would still only draw 1.5 amps.
Note that the draw can be affected by the USB cable you use. I've seen some USB cables draw less than 500mA where the stock Samsung USB cable draws 1.8 amps.
Bottom line is that you're not going to find a wall charger above 2.1 amps as far as I know, and even if you did, it wouldn't charge the Nexus 10 any faster. The problem is what you identified in your original post -- using some plain vanilla 500mA (0.5 amp) micro USB charger that you've had lying around the house for the past several years and assuming that it should charge just as well as the stock Samsung charger. It won't, as you discovered -- the N10 will only draw about a third of what it's capable of drawing from such a charger.
Be careful buying 2.0/2.1 amp chargers from Amazon or wherever, particularly if they're identified as Samsung chargers. They're almost always counterfeit, and no better than the 500mA chargers I mentioned above.
You might also want to look into the POGO charger cable because it allows the Nexus 10 to draw virtually the full 2.0 amps from the charger rather than 1.5.

Listen to this guy.
@JasW - Wow, thanks for the information / education. It makes a LOT more sense now.
Thanks again, F
@Gearhead_ENG - Thanks for the links! I'm going to go home and scrounge through all my old chargers and see if I have more 2Amp chargers. If not, I'll be following the links again to purchase...
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.
All of my previous phones' chargers have been like 1A and usb 2.0. The note 3 quite obviously differs in both of those respects. Now, I know that I can charge my note 3 using all my old chargers no problem, even if it's a little slow. But, I've got two questions.
1. Does the usb 3.0 allow more current to the phone or just faster data transfer? i.e. Am I losing anything by using the note 3 wall wart with a usb 2.0 cable?
2. If a usb 2.0 will still deliver the same amperage: Say I left the 2A charger with a usb 2.0 lying around and someone with a less powerhungery phone comes along and plugs in, will that damage their device?
Any help is much appreciated.

1. USB 2.0 and 3.0 charge the same. The extra pins are only for data.
2. No problem. Devices only pull as much current as they need.
This may have been asked many times before but I am having a hard time understanding.
I have a bunch of Qualcomm 2.0 car and wall chargers. I just ordered a nexus 6p. I have ordered USB A to C cables to make the chargers work. What kind of charging speeds can I expect from this?
I know it will charge slower than if I hooked it up to the included charger. But will it charge as fast as the quick charge chargers or much slower like when I hook my phone up to a PC and it charges very slowly.
Cue @Elnrik
He the man for this question. Please ignore my below 'theory' in brackets.
(I would say, assuming your QC2.0 have the right resistors, they will only supply a max of 2.0A to the 6P which takes 3A from the supplied Google charger. So, in short, it should charge the same speed as your other devices but will take longer to go to 100% because the 6P battery is larger. The part i'm confused about, due to conflicting reports is whether the A to C cables can supply 2A from your chargers.)

So far in my experience the a to c cables charge much slower even with a QC 2.0 charger. I haven't actually measured it but I bought a type c to c charger and cable for my office and can get a full charge from 50% in less than an hour. I use my QC charger at home for over night charging. The charger that came with it had a short cable and was useless for my application so it just sits in a drawer.
I hope this explanation helps you understand better. Let me know if you have questions.
1) Quick Charge 2.0 will attempt to increase voltage at varying current levels to charge compatible Quick Charge devices. The 6P is not Quick Charge compatible, and it requires a constant 5V from it's host.
2) Type A ports do not have a cc pin (configuration channel) to identify itself or to negotiate current with type-c devices. That is why it is the cable which has to do this for the Type A port. It is the job of the Type A to C adaptor/cable to identify (via the correct pullup resistor) to the Type C device that a legacy USB connection is in place. Using the wrong pullup resistor in a cable is akin to deliberately posting a 55mph speed limit sign in a 25mph school zone. When the Type C device sees the resistor in the cable, it knows it is connected to a non-Type C port, and will then use other means to negotiate for power. BC 2.1 (battery charge) protocols are used over the USB 2.0/data wires, and if that fails, it just defaults to legacy current rates.
I hope this post explains things a bit better: http://forum.xda-developers.com/nexus-6p/accessories/usb-type-c-vs-usb-3-0-3-1-vs-usb-2-0-t3221676
So, the short answer is: using compliant cables, your chargers should provide 1.5A to the phone, which is the limit of BC 2.1. If the chargers do not use BC protocols, then 0.9A or 0.5A should be provided. Just make sure to use compliant cables.
