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?

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.

well the battery is 1500mAh the nexus charged pretty quickly but it was 1400mAh i am not sure how much difference 100mAh will make on charging the battery but that could be a possibility.
Charging with the computer will always be slower, if that's what you're using.
I wonder if its the charger. The provided charger has an output rating of 0.7A. I know some microusb chargers I have seen are rated as high as 1.0A. That could be the difference.

Interesting...that could be. However, maybe it's 0.7A for a reason? Perhaps the battery needs to have it at that "flow rate." ???
We did get a different charger over the i9000, they had a separate USB cable and microUSB wall charger. We obviously don't have that setup.
Some phones have Li-Pol batteries and they have to charge differently. This could be why it's taking so long to recharge.
check a tmobile store or website for the new portable micro usb charger. charges your phone on the go and recharges itself via a usb charger the vibrant ships with or your computer. i got mine and was a lifesaver the other night when i needed to leave my house with 10% charged.
I hate saying this, but: I literally LOL'd from the title of this thread.
I completely agree. Charging takes fuggin' forever. My guess would be that turning the device off helps speed this up, tremendously. But of course, who wants to do that?
That said, battery life has been impressively long, provided you turn off Samsung's widgets. :/

How fast is fast, iceshinobi?
I have conditioned my battery twice and going from empty with the phone off and pluged into the wall not via usb-pc, took me over 4hrs each time.
If the charger is 0.7 going to a 1.0 would be a huge improvement. The only worry would be the extra heat and problems that might cause. With NiMH batteries quick charging is preferable to slow charging, is this the same for Li-ion?
came here for insight as well, woke up at like 5am, phone was almost dead, 10% battery or so
turned it off, plugged it in to the wall charger and it is now 8am and it is maybe 60-70% charged
what the hell?
with my g1 turned off i can go from 0 to 100% charge in like an hour or so using a USB port. now i know the battery is smaller but c'mon... this is ridiculous.
Could it be that the phone just has to break in? When I first got G1 it would take about 4 hours to charge I remember, now a year and a half later I can get it to 80-90 percent in 1 and a half.
The computer USB standard is 100 to 500 milliamp, the USB walloulet adapter (charger) Is 700 milliamp, our batteries are 1500 milliamp and that's why.
USB cables have a certain standards witch includes voltage and current standards.
If you want a fast charger look for a hard wired 1000-1200 milliamp charger with a micro USB connector on ebay.

It's more complicated than that. Just because the charger is able to provide 2.1A doesn't mean the phone will actually draw that much current.
The charge control circuitry is built into the phone. You are just providing a +5V rail as the charging power source via a standard USB connection. There is no charge control inherent in USB itself.

It will only pull as much as it needs. I use higher amp output chargers and it's not a problem. It will charge faster, regardless of what you use, if you turn the phone off.

It could be due to the usb micro charging standards... Many chargers do not adhere to the standard, and this may cause some of the newer phones (droid X, galaxy S phones) not to charge at full power. Most older phones simply did not care, and would use all the amperage they could get their hands on.
Basically, if the D+ and D- pins of the USB cable are not shorted, then the device will draw minimal power from the +5v rail. It is probably drawing <500 mah, and could even be drawing as little as 100 mah from the charger.
Getting a proper 1A charger could fix this, but I'd like to test it out myself when I get the chance..
http://www.griffintechnology.com/products/powerduo-for-ipad
These work good. I use the ac one. Only thing is, like some have stated, even when charging when phone is on and using the phone, the battery will still go down. Maybe 2.2 will fix this or a patch.
I'm not going to debate fast vs slow charging. This isn't like debating what is the best charger for AA rechargeable nimh, fast or slow or charging method.
Hi all,
Ok, so I finally managed to order a 16Gb Nexus 4 and hopefully it will be with me in 1 week or so.
And I was wondering one thing regarding the AC adapter: I believe (pls correct me if I am wrong) that the original AC adapter’s output voltage is DC 5V, 1.2A.
I will need an extra AC adapter to keep it at work and I was planning to use one of those:
- The Sony Xperia P AC adapter will output 5V, 1,5A
- The Samsung Galaxy S AC adapter will output 5V, 0,7A
It is clear that neither of those 2 chargers will match exactly the specifications of the original Nexus charger (same voltage, but different amperage).
So, here goes the questions:
1) Is there any problem if I use a charger that will output the same voltage but with different amperage?... if not, which one would you use and why?.
2) how the amperage affect to the charging process?.
Thanks all in advance
PS: sorry for terrible English
You can use any charger up to 2 amps.

You must use a 5V AC USB Adapter and better no LESS than 1A
for Fast Charge.
AC Adapter I Use:
iPad AC Adapter 5V 2.1A at Work
PlayBook AC Adapter 5V 1.8A at Home 1
Original Nexus 4 AC 5V 1.2A at Home 2.
Our Nexus 4 will Draw around 0.8A when Batt lever at 0% - 80%,
then around 0.5A at 80%-95%, Final State 95%-100% will draw 0.2A roughly.
When 100%, Nexus 4 will use the AC power & the Current "A" show on phone
will like 2mA (0.002A) when idling.
** 1A = 1000mA
As previous poster said, do not go under 1.2amp.
I run the OEM charger in my bed room, a USB charger to my computer, and a 2.1amp charger in the car.

Why do you say not to go under 1.2A? Charging from a laptop is at .5A. I've been using a 1A charger since day one. Haven't experienced any issues with it.
Charging at a lower amperage shouldn't hurt anything, just charge slower. All you have to do is make sure it's a 5V charger. Amperage shouldn't matter but a lower amp charger will charge slower. As for a higher amp charger, the phone will only draw the amount of power it needs to charge so using 2A charger won't hurt anything either.
Also 2mA is 0.002A not 0.02 A

Since the charger doesn't actually regulate the charging itself (the phone does this) it doesn't matter how many amps it can supply, could be 100 amps, no worries. As long as it is 5V, the phone will draw as many amps as it needs.
Since the supplied charger is 1.2A rated, it's fair to assume that the phone will never actually try to draw any more than that, so there will be no benefit in going higher.
Going for a lower current charger will likely extend the charge time.
I use a 2.1 amp daily without any issues.

Yes, the .7A charger will take a little longer to charge you phone.
On the other answer, I think NO but I'm not as familiar with LiPo batteries. I would venture to say that .7A vs 1.2A (max the phone will draw but I think someone above mentioned it's even less than that when the battery is very low) is not going to make a bit of difference in your battery life.
One thing I do know about LiPo's is you do not trickle charge them. So while plugged in it will charge at the rates mentioned above until full and then it QUITS charging all together. Once the phone discharges the battery to a certain level, it will charge it back up again. Probably at 98-99%.
There may be one other thing to consider when selecting a third party charger. In the Nexus 7, the device looks for pins 2 & 3 (data) of the USB plug to be shorted in order for it to draw full current. If this pins are open (or have a load across them as is the case with iPhone/iPad chargers), the Nexus 7 will assume it is plugged into a computer and limit its draw to 500MA.
Not certain the Nexus 4 behaves the same way but would assume so.

I want to make this case clear. According to my Charging log,
Here is some key point.
Nexus 4 Max Draw Rate at Fast Charge Mode is around 800-900mA,
even you use a Charger that rated at 1A (iPhone Tofu), 1.2A (Original),
1.8A (Playbook), 2.1A (iPad).
Fast Charge Mode must be with Charging Cable with 2&3 pin Shorted,
or the charger itself have the 2&3 pin already shorted.
Therefore, 1A is a Sweet spot for getting Charger & Charging Time for
Li-Po/Li-Ion/Ni-MH Batt charging.
If you use under 1A Charger, eg 700mA or 500mA, it will take much longer
to charge the batt but no harm as well. Just too slow only.

Hiya,
I'm copying my original post over from the Z3 Compact forum as there should be a fair amount of similarities between the two models regarding battery charging.
Hiya,
I' hoping this is the right section to post this in.
I don't have my Z3C yet, but I've been searching for information on charging speed, charging current etc. - and there is barely anything to be found. What seems to be consent: A full charge (0-100%) takes about three hours. But then, some people say an almost full charge (0-90%) takes much less, as charging current is greatly reduced for the last 10% to reduce stress on the battery. Sony itself also claims that a small charge (something like 0-10%) should be quite fast as well.
Then there's some speculation about QuickCharge 2.0 being used or not used, that you could use a Motorola 2.0A charger to charge it faster than with the provided 1.5A Sony charger etc., which also brings up the question which resistor values on the D+ and D- wires are necessary to toggle different charging currents. (Or I might be stupid and there's a standard for that by now, which is the same for all Qualcomm devices.)
To cut it short: I'd request those who have a Z3C to post some comments about their charging times, and at best even their charging currents. I used an app called BatteryMonitor on my Desire HD, I'm sure there's others around now that give the same information. If someone could try out different chargers and record charging current over time, maybe even with a pretty graph, it'd surely help all future discussions about chargers, docks, modifications, DIY charging issues etc.

A recent tear down confirms the Qualcomm chip for Quick Charge 2.0 support, so what we need now is for someone to get a compatible PSU that can 'talk' to the phone and then supply more power. That should see a huge improvement in charge time.
I am just trying to find a source for a compatible charger. So far I've only seen the Motorola Turbo Charger in the USA, and I'd be wary of buying anything made by a no-name brand at this point.
I have to assume the magnetic charging option won't be as fast, simply as there can't be a way for the PSU to know it is connected to a compatible device. Quick Charge 2.0 appears to require some sort of handshaking, or else the PSU will limit the power output, hence why I'd be wary of any chargers appearing on eBay or Amazon that claim to offer fast charging.

I have to assume the magnetic charging option won't be as fast, simply as there can't be a way for the PSU to know it is connected to a compatible device. Quick Charge 2.0 appears to require some sort of handshaking, or else the PSU will limit the power output, hence why I'd be wary of any chargers appearing on eBay or Amazon that claim to offer fast charging.

I have read excellent reviews for the Blackberry Premium Charger (the one with the yellow tip), super cheap on Amazon right now. Recommended by Android Central and others for its 2A charging capability. I have used it in the past from my HTC One X days and have re ordered for my Z3. Honestly, my Z3 is charging more than fast enough with the OEM supplied charger, which may be less powerful but more optimised than another OEM's charger. The one I'd trust most if I was forced to use one would be the above model of the BB charger.

more power can either be achieved through more voltage (that could potentially be harmful if the hardware is not compatible) or more current. More current is 100% save as the charging circuit just takes what it needs, independent of the (more potent) capabilities of the charger.
As Oppo showed with its find 7 just raising the current is a viable option which works. This is also a Snapdragon 801 device.
With the 1.5A original charger and cable, using Battery Monitor Widget shows the charging rate at around 900mA to 1000mA.
So I guess Z3 is restricting to max 1A charging?

Would it be possible that the PSU simply always limits the power output? For example, the phone might try to draw 1.5A, but the PSU doesn't support it and limits at 1.0A. Then magnetic charging could work with 1.5A or even 2.0A without the need for communication over the D+ / D- pins. (And attaching the magnetic port with a USB adapter to a PC or Laptop might cause the USB Port to shut down and trigger an overcurrent warning.)

That would make sense. Though wonder where the extra 500 mA are going, it surely can't be the phone's standby. And given a typical maximum charging current of 1.0C (C = battery capacity), it would translate into 3.1A of charging current and therefore a 3.5A power supply.
Is this current constant from 1% to about 65%?

If there are restrictions they are most likely within the Kernel and we may be able to change them in the future with custom Kernels

There is some fluctuation, but is roughly around 1A.

Thanks for the results. I have my Z3 by now and recorded some as well.
From 0 to 68%, it charges with 1000-1100 mA, then it goes into CV (constant voltage) mode and stays there until 95%. Then the curent drops slightly. The rest of the charging curve is not usable, as it was the first full charge my handset had. And the last for now, as I have to send it back due to a gap in the frame and microphone issues.
I'll post a complete curve when I have the new one and did a few cycles. What's clear for now:
1. Charging current with the stock charger is around 1.1 A max.
2. The phone charges up to 95% with 0.5% per minute. (Stock Charger)
3. It drops to 0.125% between 95% und 100%, likely to put less strain on the battery.
It's nice to see that there's appearantly support for higher charging currents. Though we should keep in mind that a higher current also means more stress for the battery, especailly when the phone is used while charging (higher battery temperature as the CPU also adds heat).
my Z3 came with the charging dock dk48.. it is rated at 1.8a, charging is fast
I can't speak to the Z3 (yet), but my Z1s charges nearly twice as fast on the magnetic charging dock as it does through the USB connection. As a result, I can leave my screen on at full brightness while on the dock and still charge. I would *expect* similar behaviour from the Z3.
Original charger: about 1.0A - 1.1A. Result: 3h 50p - 4h for fully charged.
Magnetic charging dock or cable: 1.5-1.6A. Spend only 2h 45p
I'm tesing Xiaomi MI Power Banki 10400mAh. First test: 1.6A, much faster than original charger. A bit surprise!

The original charger is rated 1.5A, actual charging on Z3 is 1.0A.
Xiaomi is rated 2.1A, so I guess is reasonable to expect 1.5A actual charging from it.
For your magnetic charging dock or cable, are you using the original charger?
With the original charger, I'm getting the same result with or without dock.

With Mi Power Bank, I used micro USB cable, not magnetic.
I'm using Samsung Note 3 2.0A charger. Through micro USB port, I got lower current, about 1.0-1.2A but with magnetic cable 1.5-1.6A.

I have a z3 dual .. I did not notice the second cable in the box. I have to check again
Just got this on our country's local online shopping site (shopee) for about $27 (discounted and with free c-c cable). It's actually 65W and has two USB Type-C ports and one USB-A port. The first USB-C port supports up to 65W and I mainly use it for my laptop. However, I just discovered that it actually charges my Note10+ on 45W. The second USB-C port supports up to 30W and it charges the phone at 25W. Lastly, the USB-A also supports up to 30W but it only charges the phone at 18W.
Many have asked how I knew the power output on each ports when used on the Note10+, well a few months back, Samsung added the feature on one of their updates to display different labels when charging.
On 45W charging, the phone displays Super Fast Charging 2.0;
on 25W charging, the phone displays Super Fast Charging;
on 15-18W charging, the phone displays Fast Charging;
and on 10W charging, the phone displays Cable Charging.
So there you have it, if you're looking for 3rd party 45W chargers, I suggest you check this one out as well.
I also am not sure if xda allows me to link where I got this but I'll just do it anyway. To the mods, please remove the link if necessary.

Hi, how do you know what wattage you are getting with each cable?
im using baseus GaN 65W + type C to type C 100W from baseus and the 45w work properly
Nice find! It's available on Amazon in the US for roughly the same price as your link.

The later firmware of the note 10+ has different indicators when charging. On 15-18W charging the phone will display "Fast Charging", on 25W it will display "Super Fast Charging", lastly on 45W charging the phone will display "Super Fast Charging 2.0"

Explained perfectly. I was very surprised when I saw "super fast 2.0" on my note 10+
I bought one of these chargers:
https://www.giztop.com/baseus-120w-2c1a-gan-charger.html
Due to it's 87-watt output of the Type C port, I use it to charge the Note 10 Plus in full-speed, as well as to charge my laptop, which can be charged through the Type C port.
Even if I use both Type C ports at the same time, the quality and speed of charging does not decrease either in mobile phone or laptop, which is one of the strengths of this charger.
It is compact and has a very high quality.
I have bought several Baseus products, even 2 protective cases, without exception, all have been of a very good quality, and, reasonably priced
15W charger charges in 80min
25W charges in 65min
45W charges in 56min
Are there any drawbacks with those new GaN chargers? I mean, if they aren't becoming the norm, there may be any. Are they less durable? Maybe they produce more toxic waste?

Original firmware, still running Pie, will indicate "fast charging" with the 25 w brick.
Really that's all you need or want. Stock ones with cable go for $20 stateside. My original one is still charging away even after heavy use.
One other plus for the stock charger is it will charge even at 60 VAC. I inadvertently tested that when we lost one leg of electric power overnight. Didn't phase the brick one bit... and it continued charging.
Update, got a new N10+ running on Q. With the same 25w brick, Q shows it to be "super charging". Sounds faster
Doesn't faster charging (ie. faster than rated for the phone) make the battery deteriorate faster?

Yes. Any additional stress does.
Do you think about how rapidly the battery discharges when in use? Same deal.
When watching vids which draw about 12% SOT I give it a break every 20-30 minutes.
The whole phone interior is warm much of the time too, more stress.
Just the nature of having a finite lifespan. On a heavily used device you'll get 1-2 years lifespan.
It's no big deal, simply replace it when it's capacity drops below roughly 80% of it's original capacity to avoid a battery failure which can heavily damage, even destroy the device.
Replacing the battery is just part of using and maintaining the phone.
Even the N10+'s battery replacement which isn't rated as easy really is not that difficult once you learn the tricks. Just replace with a battery made in Nam, not China and use a new OEM seal on the rear cover.
The "permanent battery" stuff is just hype for most phones. There are a few exceptions.

So you charge your N10+ daily with a faster charger? And always to full 100%?
Well, if mine would last perhaps another 2 years, even doing this, I'd already be happy

Mostly always use fast charging. Not real concerned about replacing the battery but I do limit the level of discharge/charge.
Very rarely to 100% or below 30%
Li's like frequent midrange power cycling.
Typically 40-50 to 70-85% two or three times a day.
Overnight I try to start it at 50-70%
Don't start a charge if below 72F.
Never attempt to charge at 40F or less.
Optimum start temperature is 82-90F
Cool if it goes beyond 100F when charging.
Short midrange charge cycles create less heat and stress.
