What amp charger does the Note 4 have?

Is it 2a?
I pre-ordered it and wish to have backup wall/car chargers ready to go for next week.
Tnx

It's a 2A Quickcharge 1.0 unit. Quickcharge boosts the voltage (to ~9v from 5v) when the phone is less than 50%, so you can't get just ANY 2 amp charger and expect it to work as quickly.
If you care (or are willing to wait) Quickcharge 2.0 wall plugs should ship in ~2 months. That boosts the input to 15 volts (IIRC) and will supposedly charge from 0% to 100% in about 45 minutes.

yeah I guess I can wait. I can always keep an old 1a plug by the bed for long overnight charges.
Does samsung sell oem chargers at release date?

9V 1.67A and 5V 2A is what it says on the charger
9V 1.67A is the rapid charging part

it's a dual voltage charger. 5v @ 2.0A and 9v @ 1.67A

For some unknown reason, I have a 2.1 amp car charger and cheap 1 amp ac charger. My HTC One M7 charge slow but the Note 4 charge much faster using the same charging device. I dont know what it is, but I like it!

So the charger on Samsung's website is not the same one that came with the Note 4?

I think it's the Fast Charging 2.0 hardware in the Note 4?

Not sure it has anything to do with the Fast Charging hardware. The Fast Charging works with the provided charger, which is a dual voltage one. I used my iPhone's/iPad's car charger with my Note 4 and didn't notice a speed-up in charging time.
On a tangential note: I can't find anyone who sells the Note's fast charger separately yet and I needed another one for use with the Note 4 at the office. So I used the Asus charger that came with my original 3G Nexus 7 (which remains forgotten on a shelf). It works pretty well. I noticed that the Asus charger charged all my handsets (HTC One M8, Nexus 5, Z2, Oppo Find 7) pretty reliably -- the M8 and Nexus 5 seemed to charge faster compared with their stock chargers.
Anyone who's held the Asus charger knows it's a little bit bulkier and a few ounces weightier than the usual chargers that come with smartphones these days so there may be a hardware component to it. Whatever it is, it's probably the best standalone charger I've had the cables connect via a USB port so you can use it with your iPhone too.
If you can find at a garage sale or some random tech shop, you should pick one up. Works great with everything.

I saw the Aukey 3.0 charger it became available a day or two after the Tronsmart charger. I have an Aukey qc 2.0 wall and car charger which are both excellent. I went ahead and ordered the Tronsmart charger I listed which is also qc 2.0/1.0 compatible, I should have it tomorrow. I wanted to compare the build quality between them.
Both have proven track records so more than likely either one will be a safe bet regardless of which one you choose. I'll post a follow up once I receive it!

Looking forward to your thoughts on it. I have a Tronsmart QC 2.0 car charger, very good quality.
I also noticed that the Tronsmart includes a longer USB cable, which is nice.

Hi
The Tronsmart qc 3.0 charger is very solidly built and smaller than I expected, it is close to the same size as my Aukey 2.0 quickcharger although it feels slightly bigger in the hand due to the the defined edges while the Aukey is rounded on either side and relatively flat on top and bottom.
I don't have any qc 3.0 devices at this point to be able to give a comparison of charge times between the qc 3.0 and 2.0 charging, although I don't have any reason to doubt the quoted specs since the qc 2.0 times have proven to be correct over time.
I will say that anecdotally there does seem to be a little bit of a difference when charging a qc 2.0 phone with the Tronsmart 3.0 charger, and that is that it seems to take slightly longer to charge the phone when compared with the Aukey 2.0 charger but the phone doesn't seem to get as warm when quick charging.
This wasn't a scientific test just a general observation, so your mileage may vary, I hope this is helpful. I can say that I wouldn't have any problem recommending Tronsmart or Aukey chargers going forward they have similar specs and are both priced competitively.
I cancelled my HTC one a9 pre-order after the shipping was delayed, so I'm not sure when I will have a qc 3.0 device to test it with.

Just bought the Tronsmart QC 3.0 and it came today, and Quickcharge 3.0 isn't as fast as I expected it to be... I got home from work and did a little experiment, Phone was at 6%, and as I plugged it in, I set a timer. 32 minutes into charging, my phone (HTC One A9) was only at 43%. Much slower than I expected... 37% in 32 minutes, nowhere near the advertised speed of 85% in 35 minutes on a 3300mAh battery. Airplane mode was also turned on while charging.
Would not recommend.

Even at qc 2.0 speeds, it shouldn't be charging at around 1% every minute right? or am I wrong. When I saw the quick charge statistics of 60% in 30 minutes, I imagined around 2% a minute

That fast charge 0-60% in 30 min is the test done by qualcomm in the lab. Actually there will be some errors between different devices which support QC 2.0 technology.

No I don't have a current meter that can measure USB currents. It's only 1% a minute when charging my phone. Quick charge is way too hyped up.

I always look into verified purchaser ratings in amazon while buying anything. I found the following Quick Charge 3.0 which (brands) are listed in qualcomm website (website doesn't have 3.0 listing of accessories, but these manufacturers of accessories are found:
1. JDB Quick Charge 3.0 18W USB - $26.99 (61 customers - 5stars) - http://www.amazon.com/Qualcomm-JDB-...860&sr=1-6&keywords=qualcomm+quick+charge+3.0
2. Anker PowerPort+ 1 (Quick Charge 3.0 18W USB Wall Charger) - $25.99 (45 customers - 5 stars) - http://www.amazon.com/Qualcomm-Anke...860&sr=1-1&keywords=qualcomm+quick+charge+3.0
I am still waiting on my HTC A9 pre-order to be delivered, would pick any of these. If anyone bought either of these please give me your opinions on these. By the way, has A9 received the update that would support quick charge 3.0 yet (it was told that, the new s/w update later in the year would support QC 3.0)
Edit: Also found this one for $15, and it says qualcomm quick charge 3.0. Looks very cost effective, but none of the review highlight on QC 3.0. Did anyone try this? http://www.newnow.com/products/tc-0...INWCtxjqipuNSxwZhGJVeE3T1EaAjWI8P8HAQ#proDesc

I bought this same charger too and I'm with you, doesn't seem any faster that my regular charger. the Anker 3.0 wasn't listed (or I missed it) when I ordered the Transmart or I would have ordered that one instead.
i'll check the voltage & amps in GSam next time I charge to see what it says.

I bought the JDB QC 3.0 charger on eBay from China for $18 (also available on AliExpress for $14). It seems like a good deal and good quality if one can be patient.
I do wish those of you posting performance comments would hold your water until your phone actually supports version 3.0; until then the 3.0 chargers aren't likely to be any faster with 2.0 phones (e.g. the A9 with current firmware).
FWIW the 3.0 spec defines charge voltages every 0.2V from 3.6V (some places say 3.2V) all the way up to 20V. That does not mean that all chargers offer this range, or that all devices can use these voltages (the phone determines which of the available voltages to use through time). The 2.0 spec only had a few charge voltages to choose from so the more granular voltage choices with 3.0 should be a win for all devices. All of the chargers mentioned so far offer a top voltage of 12V at 1.5A (compared to HTC's 2.0 max of 12V at 1.25A). At 9V there is 2A available (compared to 1.67A for 2.0). In the range around 5V the different products list different currents between 2A and 3A but at this stage I suspect the spec differences are probably not real (2.0 is 1.67A for comparison). So potentially 3.0 can provide up to 20% more current than 2.0 across the voltage range. In practice the greatest benefit will be to devices with large batteries (i.e. not A9) as they can absorb charge faster - it is quite possible that the A9 will not benefit from the higher available currents at all (but still benefit from the smaller voltage steps). I look forward to getting real world measurements.

I just did a little experiment with my HTC one a9 and my old iphone 6. I used both till they are the same battery level (16%), and (With airplane mode on for both devices) I plugged my HTC to the tronsmart qc 3.0 adapter, and my iphone into the HTC charger that came in the box. A little while later, I checked the percentages and they were exactly the same. Either my HTC is charging at conventional speeds, or the iPhone charges at the same speed as Qc 2.0 (Roughly 1% every minute), Never owned a Qc 2.0 device so not sure if that's the normal speed... Anyone have any input on this?

It's not just comparing apples and oranges, there are multiple differences: battery capacity, age, and charging regimens available in both phones and chargers. I don't see any comparability. As for charging regimens, the new A9 is a QC 2.0 device (for now) charging on a QC 3.0 charger, which means the CPU will only request voltages that are available in QC 2.0 and only with slightly higher amperage available from the charger (which may not even be usable with the A9's small battery). So I expect little or no improvement over a QC 2.0 charger. We will have to wait for a test of QC 3.0. The iPhone uses Apple's own charging regimen, which usually doesn't charge fast unless connected to an Apple charger, or one able to act like one. I suspect the QC chargers have that ability, as it is increasingly common, so the question is how much current is available in the charger for the Qualcomm implementation of the Apple protocol?
I think the identical charging times is just an accident.

So you're saying that QC 2.0 is supposed to charge at 1% every minute? That's very slow compared to Qualcomm's advertised speeds. And if the iPhone 6 charges at the same speed as the HTC One A9, then does that means the iPhone supports QC 2.0? I find that weird because Apple's specs say nothing about quick charging.

I am not sure if it is 1% per minute. My M8 charges 70% in an hour. QC 2.0 is the technology of qualcomm and nothing to do with Apple. Apple doesn't use the the qualcomm technology but they have their own, and advanced Apple iPhones have charging capacity similar to QC 2.0 . QC 3.0 is going to be the new technogy when qualcomm makes it available through HTC update, which we are expecting to be a great upgrade (which is not available on A9 yet, though the hardware is all set to do that)

QuickCharge 3.0, across 6 chargers, is somehow not working on my V20

I picked up a T-Mobile V20 2 days ago. Rooted it the same night, and tested out a few chargers I had laying around to make sure the ones I had, along with cables, worked properly after having most everything not work properly with my Pixel XL.
The stock charger would not charge my phone at more than 3 watts (but I never touched the stock charger until I started noticing the issue).
A Samsung QC charger, with any cable, would not charge my phone more than 9 watts.
An Anker PowerPort+ 1, Type C, QC 3.0 charger, with any cable (to include Anker cables and the Pixel XL OEM cable), will not charge over 12 watts.
Absolutely NONE of my QC 3.0 car chargers register as "fast charging" - these include an iVoler Type C and USB A, Anker USB A, Tronsmart Type C, with various cables. A standard cabled Type C charger from i-Orange does not say "fast charging," but seems to be charging at 5V/3A as it is MUCH faster than all the others.
The ONLY charger that is fast charging my phone is the Pixel XL OEM charger. Measured at the wall, it has peaked at 19.2 watts.
I'm really confused. I don't know if my QC 3.0 has been defective since I got the phone, or if plugging my phone into the USB PD Pixel XL charger somehow screwed things up...
Does anyone have any ideas here?

All my old QC chargers work and I'm currently using the note 7 oem one atm as it does not get as hot (charger not phone) as the LG oem one under load. What does the app ampere say your getting?

It takes a while, try a very low battery and give it 10 minutes or more screen off, must be cool too

I got an existing aukey qc 2.0 fast charging fine while using a Samsung adaptive fast charger also fine, I am waiting for my qc 3.0 aukey one to be arrived possibly tomorrow to see if I could charge faster and lower temperature than my existing ones, I cannot check the watts though

My phone is either defective (not surprising given LG's GARBAGE quality control) or the software has somehow screwed up from root, etc. (highly unlikely as I am the only one with an issue).
With that said, I made an interesting discovery. My phone, using USB Power Delivery, charges much faster than my girlfriend's, using QuickCharge 2.0 or 3.0. I tested this 2 times from 5% battery on both phones. I tested this with a QC 3.0 car charger and the OEM QC 2.0 charger. The difference is substantial... first test was about 40 minutes. My phone was near 80%, hers was at 55%. The 2nd test was only 15 minutes. Mine was near 40%, hers only 27%.

Don't remember what Ampere says, but it was <500mA. Also, I used a USB current meter. It hovered around 5V/0.5A no matter what charger I used. I don't have a Type C/Power Delivery current meter, so I couldn't test those chargers... but USB PD is CLEARLY working very well on the V20. Much better than QC.

It does not take awhile - takes <5 seconds to begin the QuickCharge process. Phone does not need a very low battery - will show fast charging regardless of the %. Does not need to be cool - fast charging is shown when the QC handshake occurs - not based on actual charging current. My girlfriend also has a V20. Every charger I tested with mine (which did not work), successfully QuickCharges hers.

Are you you using 56 k resistor cables?plus being rooted a kernel app would have a section to disable fast charge or enable it. Most devs disables by default. So if using custom kernel something to look in to. As I doubt there is anything wrong with your phone.

All of my cables are good. No custom kernel, and I've never seen a dev disable fast charging by default... that would be very unpopular.
Anyway, it seems that LG's recent phones, to include the G5 and V20, are actually supporting both QC 3.0 and USB PD. This is also probably why QC 3.0 chargers that use Type C do not work (the Anker PowerPort+ 1 in my case). On a C to C connection, with USB PD present, USB PD will take precedence over QC 3.0 (since QC 3.0 is illegal with C to C anyway). But that still doesn't explain why my phone doesn't QC via USB A to C... so I'll chalk it up to LG's garbage quality control.
I'm glad it worked out this way. USB PD charges my phone WAY faster than QC 3.0 charges my girlfriend's V20. So I would suggest you all dump QC 3.0 (because it's non-compliant to anyway) and grab USB PD equipment since it's the way of the future anyway.

I'm starting to think that there's something wrong with the way V20 handles QC 3.0. I'm in a somewhat similar situation with you, tested three different QC 3.0 using almost 10 different A->C cable (including the OEM cable) and none of them would deliver QC 3.0 speed. (I just came in a from Axon 7 and the difference between charging speed is night and day).
Additionally, I wish there's an app to properly identify what's going on during charging.
Using the built-in battery test from Service mode (see screenshot), it always says that I'm on QC 2.0 whenever I'm charging using QC 3.0 chargers.

My unit (LG-H990DS) is charging very quick though.
Using stock charger & cable, charging time is very consistent from 0 to 100%. 95 mins is all it takes.

The stock charger that LG sent with the V20 is actually a QC2.0 unit.
and with QC3.0, it'll take you less than an hour to fully charge.

I can't say for sure, because I have no way to get a baseline on how fast a QC 3.0 charger charge at the correct QC3.0 rate on the V20....
At least according to the battery test from the service mode menu, none of my QC3.0 chargers are being recognized as QC3....and it definitely doesn't charge as fast as 3.0 based on my previous experience with axon 7.
on The Axon 7, I can still be playing Mobius FF (which is very battery intensive) and still charging up at about 1% per minute.

I'm pretty sure our phone doesn't have QC3 as I just mentioned in another thread. I'm like.. 97% sure? I remember reading early on that it was QC2, and a blend of LG that got it a little more robust than that. I'm not sure all of what's required for QC3 to work, obviously the 820 SOC supports it, but, not sure why I read that we don't have QC3.,

Yeah, I'm starting to believe that's the case now. I just updated the thread btway, now they're saying that 3.0 isn't enabled by LG.
Not sure this is the case of Tmo employee not knowing their sh*t or what.

FWIW, I have a couple of Aukey chargers. One is QC2, and one is QC3. They both "fast-charge" my phone, but I don't think I get the fastest charge on anything but the LG adapter. Usually it's fast enough for me, but I guess if I was 10-15% left, and I needed 100% in less than an hour, it might not happen.

I just picked up a US996 (Unlocked V20)... and found this site while trying to make a decision on buying new chargers, cables, etc.
I opened a chat with LG to ask them if the V20 supports USB-PD... and I got this response:
Merwin
Not that we can verify, Ryan we because we have not tested it. I highly suggest you to use the OEM charger of the V20.

So... no help from Merwin @ LG. It seems they're not allowed to comment on it, and can only recommend the OEM charger. I was unaware that it was only QC2.0, according to the testing above.
Has anyone done more testing since? Can I buy a USB-PD charger and C-to-C cable? Should I avoid QC3.0?
Thanks

I'm interested in this as well having bought 2 QC3 chargers and neither charge my phone as fast as QC3 advertises.
I have used my brothers stock Nexus 6p charger from Google and the times are about equal to my QC3 chargers I bought

I'm using a Samsung QC 2.0 charger for mine:
https://www.amazon.com/Samsung-EP-TA20JWE-Travel-Charger-Devices/dp/B00TEUVEIO
I use it because I lost the LG one. It does quick charge but I can't measure the rate in the service menu. It just stays blank.

This is real easy, it happens with qc 3 on my v20 and s8+
The phone does not quick charge when the battery is warm or when the screen is on. Its really that simple. You can get faster charge times using a qc 2.0 charger or a dumb 18 watt adapter. Neither one is as picky about sending power to a warm battery, but your batteries life will be shorter than it was designed to be.
QC 3 will charge a cold empty battery faster, but in real life, it will preserve your battery over fast charging the phone.

Question about weird fast charge Galaxy S8+

I have 4 chargers on hand listed below...
1. Original Samsung Adaptive USB Charger
2. Anker PowerCore+ 10050+ QC 2.0 Charger
3. Anker PowerCore 10000
4. Pleson Fast Wireless Charger
Now my question is why is my S8+ charging similarly with all these chargers? Example @ 30%.... The Adaptive charger says 1 hr 9 min (reads fast charge), the Anker 10050+ says 1 hr 25 min (doesn't read fast charge), The Anker PowerCore 10000 says 1 hr 25 min (Not a fast charger), and the Pleson Fast Wireless Charger says 1 hr 44 min. I am confused.

Because only 1st one is actually fast charging your phone.
You should try 2 and 4 with original cable. If you have qualcomm version of s8 shold work

I'd echo the original cable and the wall plug that came with the device. Retry all 4 of these with the original cable and the wall plug.

Well I don't know if the Anker products are charging oddly because one is QC 2.0 and the other isn't, yet both have same 59 min charge time. So I question is the Samsung Adaptive charger is charging slow or fast? Here are some pics of the remaining charge with original black USB Cable.

From my experience, Samsung Devices don't really play nice with qc certified devices thanks to Sammy doing their own thing. What you are seeing is what made me buy Samsung's power kit.

I have no issues with my chargers, use stock charger blk, use sammy wireless charge pad with aftermarket cable and s7e wall plug charger and no issues. Still get fast charge. I even have a portable 10000mah sammy pack and use my gopro usb-c cable n gef fast charge.

Do you mean this one....

Had similar problem. All my Anker QC2.0 doesn't fast charge my S8 while 3.0 does. got them both refunded while they are investigating.

Strange
does that mean S8 has QC 3.0

Yes I am in talks with Anker as well, seeing what they find out about my QC 2.0 Anker charger.

They sent me another QC 2.0 car charger, and it did not fast charge. I am going to try Berkin USB-PD car charger and see how it goes.

Estimated time. Don't expect them to always show exactly the time.
I have QC 2.0 and 3.0 chargers and they all "fast charge" but I don't expect what the estimated time show to fully charge be accurate or else they wouldn't say estimate.

Yes except bestbuy carries that with a dual Samsung fast charger for car and a nice wireless upright fast charger all in one box for about $99 on sale every other week. Way more consistent everywhere now.

Compared to my s7edge this s8+ charges a lot slower. The s7e would fast charge and wirelessly fast charge from any third party wireless pads/adapters.
The s8+ is finicky about what activates fast charge (especially wireless) and even while in fast charge it does not charge as fast as s7.
My guess is samsung slowed the charging down to help with battery degradation.

I found a weird thing last night when I set my phone to charge at 2 AM with about 7% battery just to wake up around 6 AM and it being at 86% charged. That was a long time, I don't know what's going on. Either the phone isn't quick wireless charging or the Pleson Fast Wireless pad I have sucks.

So, I've seen this behavior too. If you see the charge stuck, unplug the cable and plug it back in. I'm not sure why, but that fixes the issue immediately.

Are you guys charging in a warm room? S8 will stop charging if the battery exceeds a certain temperature. Samsung really went overboard with battery safety after the Note 7.

[CONFIRMED] .152 Firmware Update ENABLE QC 3.0 Fast Charging.

EDIT : Confirmed. This phone support QC 3.0 now.
Come a bit as surprise,
Updated my P20 Pro C636 to .152 Firmware,
And noticed right away that now IT DETECT my QC 3.0 battery pack charger as Fast Charge (Two Thunder Icon Appear) and it charge with High Current,
Someone who already on .152 and have QC 3.0 charger in their belonging might want to test it as well.
But anyway, this is good addition for me. Since now i can have one battery pack to fast charging all my phones.
Bellow i attached the picture

I have 70% of battery and it says 1 hour 30 to full the battery capacity
with wall quick charger with usb3 cable type or with original huawei cable
what about you?

By "wall quick charger" is it QC 3.0 ? Or 2.0 or standard fast charger ?
Because this phone wasn't meant to support QC standard to begin with, and supposed only work with Huawei Proprietary Supercharge technology, thats why i quite surprise when it now show it as fast charging when am using my QC 3.0 charger.
How many Thunder icon you see next to the battery when you charge ?
And, are you on .152 as well ?

*double post* crappy connection. and this xda app been slow like, for months

I see,
i never got .134 on C636
but means it confirm that it works with QC 3.0 charger now, which is a good news for everyone.
less kind of charger to buy. since one will do now.
thx for confirming it
i just checked with voltmeter as well, and it indeed charge on 9V as well

Not to burst the bubble but fast charge through Huawei's own charge gives up to 4.5A, yours only gets 2.5A and that's not fast charge but possible quick charge that Qualcomm uses.

Yes, that i know. LoL
but prior to this, even using QC 3.0 charger will only give me less than 2A, since it only act as normal fast charging,
so, this might be not doing any miracle,
but at least now i know my QC charger will fast my phone faster than it previously does.

i don't have mine on me, but that doesn't sound right at all. even from a dead phone, i think i'm fully charged in under 2hrs, maybe 90 minutes

That calculation on the screen is innacurate for most of the time. Because it fluctuate often.
And since his battery is on 70 its normal that the charger doesnt supply full current/volt,
That just how it designed.
And you are right,
For most of the case, our phone will be fully charged in around 2 Hrs using supplied charger

Stock Huawei charger includes both supercharged capable adapter, and cable (look for purple ends)
Outputs 2A, 5A, 4.5A

Uhmm that's interesting.
I resumed my old powerbank I used for my old nexus 6p, it's a Tronsmart and it claims to be QC 3.0
Fast charge was working with 6p, I plugged in the p20 pro and I don't get your results.
I'm on c636 152, charge is still normal.
I don't know if the powerbank lies, or the cables, but I tried different ones.
What cable did you use?

QC 3.0 cable or USB PD C to C cable. Both works

I have a QC3. 0 battery bank and it doesn't fast charge my phone.
I'm on 152.

How can I update my p20 pro to the latest version while keeping all my data and stuff?
Once I done this I can confirm this for you guys as I have a current and voltage meter which I can use to confirm that it is indeed charging at QC3.0 speeds.

I was actually asking how can I update to this.

I don't get the double charge icon even with the default charger, I don't know where it comes from
