I guess you could consider a aftermarket charger a accessory....... so ive seen on here that every one is pretty satisfied with the 2amp charging speed on our phones, I had a 3amp charger (lost it) that I tried to charge my gs3 on and the battery got really hot. I wonder if a 3amp usp port would charge the gs4 faster?? Or just be a wast of money?

Imo its a waste of money... I personally am still going to use my 850mA chargers in most cases, but Ill keep my 2amp nearby in case I need a quick 20% mid day

S4 has a hardware limitation on charging current, right now it won't go above 1100mah while charging which is 1.1a, perhaps in future with kernel development we'll be able to raise the charging current but for now purchasing a charger above 2a would be completely useless.

On this point what you need to realize is that the usb cable loses a bunch of the power on the way... so like, a 3 foot cable might deliver most of the power to the phone ... a 10foot cable might only deliver 66% of it... so really a 2amp charger is whatthe s4 needed but going above it is kind of useless
The S4 actually goes to 1,910a when charging, I've checked with and app (galaxy charging current) that's why it charges so fast
Mine shows the same thing

Do the lights dim everywhere in your house?
Oh and guys/gals, you cannot get around Ohm's law. 2A at 5V is 10Watts. You can use a 10A (50W) PSU but your phone will only use what it's designed to charge at unless you increase the voltage which I don't recommend unless you like to smell burned electronics.
Larger power supplies do have an advantage, however. You can charge multiple devices at the same time, i.e. a tablet, phone, spare battery, all at once. Good to prepare for a storm like we had last night here.

Haha yes I figured, just being sarcastic, no harm meant.
I will add using this app I find interesting results of cable length vs. mA delivered. If you want to charge fast use a shorter cord.
I may connect it to a bench supply and see how it reacts to a gentle overvolt, say 5.5V. This could be what's needed to compensate for a longer cable, i.e. getting ~2A with a ten foot cable!

The currents which we're discussing when charging apply from the phone to the battery which subsequently uses the battery voltage as a charging indicator. Those 1.9A only happen at low battery percentages with voltages around 3.6V or lower, with raising voltage the current is limited. This is basically what QC quickcharge is. I don't really see the gimmick in it, as such a logic could be emulated in software on any phone.
What charger should I use? It comes with the wire but no adapter. What voltage should the adapter be as I do not want to ruin the battery of the Moto G.
I have a Samsung Galaxy S2 and HTC One X charger.
Any USB charger will be fine, they're all 5v. The cheaper ones will have a low mAh though.
Both your Samsung and HTC ones are suitable.
No charger? thats a bummer..
it means that charging time would be varied depending of the source. Not a wise move here by Motorola since people might buy cheap charger and ruined the user experience. Especially when they're targeting 1st time smartphone consumer in less develop country
hmm..
It's going to get more and more common as the world is flooded with USB chargers.
Well not really true... Here in germany every shop adds the adapter to the package themselves. Most of them added a 1000mA one, because it doesnt ruin the battery that fast. You can see that in pretty much every unboxing video. But in fact we e.g already got like 5-6 chargers in our households, so what...

As it would be my first smartphone, I'm looking into the wall plugs. I've found one in my local shop for ~10 euros. It's from Philips, with 5V/10,5W/2,1A and has two USB sockets (that's why it's 2 amps).
My question is, as I've no experience with smartphones, how long would it take to charge from 0 to 100?
With that charger it would take roughly 2 hours to charge your device with 2075 mAh battery.
The Brazilian 16gb dual chip edition comes with a charger.

LOL... I was surprised as well, when got the box (a tiny package similar to iPhone) and found only phone and USB cable inside.
But don't worry, any charger with 1A will do the job, so your chargers from S2/HOX will be OK.

That's nice attitude towards customers...
I am using the old HTC charger (1A),which came with HTC Diamond (has a nice glowing HTC logo ) and its OK. It charges battery fully within 100 minutes when phone is OFF.
Will try also 400mA (Alcatel) to see what's the difference.
I use only branded chargers, as had issues with some cheap aftermarket chargers in the past.

It may depends on phone make/model.
I've used few times 2A charger from Samsung Note 2 and phone/battery become hot and battery didn't lasted long... Also during charge it had hissing sound, so back to 1A chargers and all OK.
I think lower output does charge battery longer, but battery last longer as well...
Will get back when charge with 400mA charger (probably on Tuesday or Wednesday )

I think with pretty much with every Snapdragon chip you get the bundled PM chip, and the last bad experience I had with a Snapdragon was with 8225/q and that was just inaccurate battery reading. I would think anything newer would handle 2a charger just fine.

I only partly agree with you here. Although the Moto G will restrict charging to a maximum of 1500mA, so using a 2A charger will not cause any direct damage to the phone circuitry or immediate damage to the battery; using a higher amperage, fast 2A charger to charge at 1500mA over time will likely cause more reduction in battery capacity. See this XDA post for my logic in coming to this conclusion:
http://forum.xda-developers.com/showthread.php?t=2564158
UPDATE and CORRECTION:
I have more authoritative information directly from Battery University that changes the conclusion I draw above based on my effort to extrapolate from the Battery University website article.
The extrapolation I did in the post listed above was based on the additional loss of battery capacity cited when going from a 1C to 2C charging rate. But according to direct communication from Battery University, when charging at a rate below .7C there should be no measurable improvement to capacity by using slower charging rates. Charging above .7C would still be expected to add more stress to Lithium Ion Polymer batteries and likely add to long-term reduction of capacity.
So, what this means for the Moto G and Nexus 5 is that there should be no measurable difference between charging with 2A, 1.2A, 1A, or 850mA chargers as far as effect on long-term battery capacity goes. Both the Moto G and Nexus 5 are supposed to automatically restrict the charge rate at 1500mA even when using a faster charger, which is just at or below .7C for both phones. So, as long as the charger dependably keeps to 5V, a higher amperage 2A charger will be faster but pose no problem to long-term capacity.
Hey guys, does anyone know a tweak where my phone will stop charging at like 99% so that when I charge overnight, it doesn't over charge? Or is this already a feature in many custom kernels such as elementalx

With all my phones, I've always left them charging overnight. As jd1639 says - they are designed to ensure they are not overcharged. This is both to protect the phone and also not to waste electricity.
I use an old Motorola charger by my bedside which is rated at 500 mah. As it's going to be plugged in for 7 or 8 hours, it might as well charge slowly! It's better for the battery that way - maybe see if you can pick up a lower-rated charger if you want to be extra careful.

I've not heard that anyway, but is 500 mah "too slowly"? That's the output you'll get from a USB drive.
Ah right... Just looked it up. If it's an ac wall charger. It's ok. If it's a usb port they generally give out less voltage (around 4.2-4.5) so your battery won't last as long between charges

If the battery is fully charged it shouldn' matter what voltage was used to get there. A full charge is a full charge.

This isn't true. A charger only works by applying a voltage to the cable which causes electrons to flow into the battery. The N5 battery is at full charge at 4.2V. If you're charging it with a supply that is running at less than 4.2V it will only charge up to the voltage applied.
Edit: I guess to clarify I should say that you're right that a "full charge is a full charge" but you will never get to a full charge if you are applying too low a voltage. And keep in mind that if your USB port is only providing 4.2A there is a voltage drop across the wire so you would end up with a lower voltage at the battery.

Hello,
I've just got an M9 and am happy with it. Thought I'd make the most of the quick charge tech so I brought a QC2.0 charger from amazon:
An Aukey Quick Charge 2.0 42W 3 Ports USB Desktop Charging Station [sorry, can't post links yet]
Reading the reviews, and also other threads on here, that people with M9's using QC charge very fast but mine just isn't.
Right now it's taken just oven an hour to charge to full from 49%. Nothing like what other people are saying.
I've contacted the supplier of the charger and they've just sent me another one but it's exactly the same. How should I continue testing? How would I determine if it is the Phone?
The only issue I can potentially identify is that after around 75%-80% the rate of charge seems to drastically drop off.
Any insight would be great !

regarding the drop off after 80% thats perfectly normal for QC, it will be quite rapid up until about 80+% then sort of trickle.

Hi, Yes using the correct Orange QC port on this charger.
Perhaps you could share what sort of charging times you're getting with your official charger?
Also worth adding there may be an 'offical' HTC charger but all that should matter is if it's Qualcomm QC2 licence device, which it is and is listed on the Qualcomm website
So I'm back to my original question, how can I tell if its the phone?
It would also be good if anyone with an M9 and QC2 could post their charging times

Something else to try would be disabling HTC's car app as it causes issues with charging. Open the car app>go to settings>disable all settings.
Go to phone settings>apps>car>uninstall updates>disable.
I use a Choetech 60W Quick Charge 2.0 for mains, and a Choetech 51W Quick Charge 2.0 Car Charger for the car. The car one is ideal because it has a blue LED for normal power which changes to green when it's using Quick Charge, to give you an indicator it's working.
I get between 1% and 2% charge a minute depending on how hot the battery is and what is running (Viper 4.0.1 ROM - Android M). Usually around an hour and half for a full charge.
Yours doesn't seem excessively slow - make sure you try when your battery isn't hot and when no apps are running in the background. Maybe useful to run the Ampere app to see what the current battery drain is before you start... ideally should be 200ma or less.
Drop off after 80% is normal, ~1% every 2 minutes.

I had the same problem initially with my QC2.0 chargers, finally found out the cables(including the one packaged with the charger) were not up to the task........eventually started getting slow charge warnings.
I use these: http://www.amazon.ca/gp/product/B013DOCZAC?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00
Haven't had a problem since
QC is only effective up to 80%, after that it will slow down so as not to cook the battery. This isn't just QC2.0, this is all forms of quick charging. Lithium based batteries must be very carefully charged as overcharging will lead to devices exploding. Just ask the hoverboard manufactures. As such the charge speed slows down after about 80% capacity. To further confuse things, a battery does not have a physical capacity like a gas tank or other physical holding device. Things like load, temperature, and age all change the available capacity. Capacity %, much like signal strength bars, is simply an estimation done with unknown calculations by the phone vendors. If you really want to know what's going on with your battery, you have to get an app like GSam Battery Monitor that will show you the current voltage of the battery and the charge/discharge rate in milliamps.
I'm using the same charger and it charges from 5% to 100 in 1hr and 20mins

Yeah ...That's why I asked. I plugged a meter to the charger and never saw it go more than 5v 2a.
I think it needs a special cable for the 9v but I can't find any info.
2.5h is not fast charge. My old s6 edge plus used to take around 70-80 m from 5-100% if if you put the remaining 1000mah shouldn't take that long lol
Mean in 30 min 40% recharge . My phone 0 -100% charged in 2:00
trust me, it is fast charge
calculate for yourself: original huawei charger is rated at 9V 2A, thats 18W total. 2A is 2000 mA. mate 8 battery is 4000 mAh.
best case scenario: 4000 mAh / 2000 mA = 2h
now add to that the extra time it needs to charge from 85-100%, because at 85% it automatically slows down charging to prolong the health of the battery and youre at the 2.5h FAST CHARGING time
also, i dont believe for a SECOND that the S6 edge+ charged that fast in your case. check this review: http://www.trustedreviews.com/samsung-galaxy-s6-edge-plus-review-battery-life-and-verdict-page-6
"Fast charging comes as standard with the S6 Edge+ and it works. It charged from 0 to 100% in just 1 hour 45 minutes. Samsung claims wireless charging has also been improved – it’s 27% faster on the Edge+ compared to the normal S6 and S6 Edge."
so thats 105 minutes for 3000 mAh. add to that 33.3% to get to 4000 mAh and u get a total charging time of..... 140 minutes. which is 2 hours and 20 minutes

trust me, it is fast charge
calculate for yourself: original huawei charger is rated at 9V 2A, thats 18W total. 2A is 2000 mA. mate 8 battery is 4000 mAh.
best case scenario: 4000 mAh / 2000 mA = 2h
now add to that the extra time it needs to charge from 85-100%, because at 85% it automatically slows down charging to prolong the health of the battery and youre at the 2.5h FAST CHARGING time

I will make a full test from 0 to 100. I only charged from 40 to 100 and it took way more than 2 hours... that's why i asked if any special cable was needed. And as i told i mesured the charging rate coming out of the charger and never passed the 5V.
As for non Believing. It's REALLY pisses me off when people write that crap. Why would I lie? what would i gain from it? I sold the phone because i wasn't happy with it.... On the contrary and in case you don't know most sites like the ones you post are PAID to give positive reviews.
I checked with including charger and cable and the app Ampére and it charged with 2800mah. So, in ideaal situation it means a charging time of a proximity 1h and 26min. That means "fast charging". At least in my opinion. ?

that doesnt make sense what ure saying because in this case the site actually stated a HIGHER amount of minutes that it would take the s6 edge plus to fully charge from 0-100% so what now, theyre getting paid to write negative reviews as well?
also, no, ure not "gaining" anything from that, but people tend to exaggerate a lot, do a quick "drive by" in a thread and post random statements based on non-correctly remembered experiences and this is exactly how false statements are converted into "truths / facts". read my post and tell me where exactly i listed anything wrong. check various reviews on the mate 8, they all stare the same thing: about 2.5h for a full charge, give or take 10-20 min. it also compares perfectly with the charging time of the s6 edge+ in terms of mAh/min, and in fact these two phones are indeed VERY close, mate 8 being at 49mAh/min and the s6 series at around 50-52, so just marginally faster... which, again, is also represented by the numbers i listed in my post before
and again: there is NO extra message or notification stating ure in fast charge mode on the mate 8, it just does its job, thats it!
if ure getting slower charging rates / voltages, make sure to use the original charger and original cable and both with a proper high voltage power outlet.

I noticed the fast charging only really kicks in if you leave your phone alone. But if you keep using it while it's charging, it just charges at regular speed. But the moment I put the phone down and screen of for 5 minutes, it quick charges like crazy

I hadn't tested this. After i turn off my phone, a few minutes later it jumps to 9V 2A on my meter. If you turn it back on it goes down to 5V 1A. Must be a phone security thing, which is kinda cool in a way if you ask me.
Btw Apparently quick charge works with non original chargers too. I have a Cheotech 60W 6 port usb with 2 Quick charge ports (which supports 9V 2A/ 12V 1.5A) and it works Using the original cable though.
Don't use fast charging unless you really need it.
Always fast charging overnite (when you're not actually using the phone for many hours) can only shorten your battery longevity more quickly then with normal charging.

When I'm going to recharge for many hours overnite I use a 1A travel charger.
i guess thats the best way to restrict charging amperage although it shouldnt hurt the battery so much, considering that the amperage drops off sharply once level reaches 85% and above...

Charging a phone with a lower rated current, will cause the charger to "try and match" the current requested.
Amps work in that manner, the device determines the draw. For example, using a 5v 5a (theoretical device) on a 5v 1a device will likely melt your adapter / screw up your phone from improper voltages.
In that case, an adapter may heat up, or if its smart enough (unlikely), it will turn off periodically. Most of the time, it will have an unstable voltage (undervolting) which is how some phones are able to detect an improper charger is used. This is bad for your battery.
I do not recommend charging with a charger that isn't rated for it. This is widely documented.
