AC charger, is yours 2.0Amps?

I'm really curious why people are saying their Note 3 charges so much faster than the Note II. I'm experiencing identical charging speed for my Korean Galaxy Note 3.
With an external changing case with the included 2A charger that came with the Note 3, I can go to 5% to 100% in exactly 2.5 hours consistently.
Through the USB port 3.0 on my computer, and since the USB 3.0 mode doesn't stay on for more than 10 minutes while idle, the charging is painfully slow through the USB 3.0 port. It'll probably have to go 8 hours.
I haven't tried it but, I'm guessing charging from the AC while the phone is on is going to similar to what I was getting on the Note 2, which is around 3.5 hours.
Are any of you getting different/same results? I'd love to know how many amps is your charger. The Korean Galaxy Note 3 came with a charger that had the 5 pin micro USB cable hardwired into it and it says 2.0A

My Charger is 2.0A. It's a travel adapter with a USB port on it. It definitely charges a lot faster than when connected to the PC but my PC isn't USB3 so it's not quite a fair comparison. I'm actually wondering about the travel adapter as its USB port isn't blue so I wonder if it's USB3 or not, or if that makes a difference.
I'm curious, what do you mean by "USB 3.0 mode doesn't stay on for more than 10 minutes"?

Note3 charges more or less same speed as note2 for me.

The charger that it comes with is slightly higher than the standard 5 volts.

A person at one of those phone kiosks actually told me the Note 3 comes with a 3AMP charger because it has 3GB of RAM!

My charger is 2.0 amps also as for usb3 charge I got a latest Asus motherboard that in a specific usb3 port gives 2amps so usb charging is same for me in there.

My ATT version GN3 came with 5.3V 2.0A charger that looks exactly like my wife's S4 5.0V 2.0A charger. Her cable is standard mirco-usb and the GN3 is 3.0 micro-usb.

My charger that came with the phone is 2.0A & 5.0V.
It charges (draws current) at 1,200 mah
When it reaches 100% charge, it draws 1,800 mah.

I second this ridiculous statement!

my note 3 also charges at 1.2A with either usb3 or usb2 cable (from my note 2). My note 2 charged at 1.8A...I'm not seeing any faster-charging benefits...I used the galaxy charging current app to measure.

really? current draw increases after 100% charge

Did you reverse these numbers or does the current draw actually INCREASE

Im using a usb voltage/ampere tester adapter which sits in between charger and usb cable.
I can safely say that my original charger with cable charges at 1.8amp. And yes, the voltage is noticably higher than other usb chargers for some reason.
Please do note than delivering 2amp power requires good quality cable. I have tested 3 different cables (original, flat & retractable) with same original charger and the ampere difference is huge. (1.8a, 0.8a, 0.6a).

I noticed that when using the "Galaxy Charging Current Lite", if I refresh while it has been on for awhile I get 1200 if the screen is off and then quickly turn on and refresh I get 1800. I assume the 600 drop is due to the screen being on?

Quick Charger 2.0 not working on Z2

Hi guys,
I have an D6543 (Brazilian Model), there is no difference between D6503.
I checked the Qualcomm website a lot of times, and Z2 is in compatibility list: https://www.qualcomm.com/products/snapdragon/devices/all?feature=Quick Charge 2.0
So, I purchase the Tenergy Quick Charger 2.0 at Amazon, and for my surprise, it's not working at all. Only normal charging.
I tested at 1%, and in 30 minutes only 11% was charged, VERY, VERY slow.
The light indication at charger is saying that is on normal charging.
I'm really frustrated.

Fastcharging is disabled on xperias for safety
Charging should be between 1-5 hours even without fastcharge

My z2 only take around 2 hours to fully charge from 1%. Just using the stock plug charger.

I dont think fastcharge is at all posible with the Z2
It charges at 1500mAh using the factory provided charger and trying to go beyond that isnt safe at all.

i dont know about it, but ive charged my z2 several times from 1% to 100% only take 2 hours - 2 hours and 30 minute. And yes, i've heard people charged thier z2 atleast 4hours to completly fully charged from 1%. My phone is still standard, under warranty(havent mod anything yet and still unrooted).

I don't know why. Z2 has the Snapdragon 801, which is compatible with Quick Charger 2.0, as Z1 was compatible with QC 1.0.
LG G3 also has the 801, but LG does not enable the QC, that's why it is not at Qualcomm's website. It's weird, because Z2 was recently added to the list, and the main product page says it's compatible.
In the end, I just lost money because their poor support and information.

Not exactly poor support, if its safe to use and certified safe to use sony would have put it in the features list on their website but it wasnt there when i bought the phone nor when i last checked.
As said check my reply
The device charges at as fast as it safely can with the factory provided charger

I'm using envi rom.
I have a normal 2,2A usb charger.
When I use the usb port to charge i have really slow (6h from 0 to full charge) to reasonable charge time (3h from 0 to 100) depending on the used cable.
But when I use the magnetic aftermarket cable than I get insane charge time, only the last 10% from 90 to 100 is not fast but it certainly uses 2A as it is from 0 to 90% in about 90 minutes.
The phone gets slightly warm but far from the temperature it gets with intensive usage and the magnetic connection gets warm too, but nothing alarming imo.
The full metal and glass design makes heat diffuse very fast.

That sucks I'm coming from a one plus one and the charger was very fast.

Xperia Z2 and Z3 supports Quick Charge 2.0.
You need charger which supports Quick Charge 2.0, though.
http://weekly.ascii.jp/elem/000/000/223/223383/
This site is in Japanese, but it says you'll get 13W when you charge with charger which supports Quick Charge 2.0 and with normal charger you'll get 10W.
Normal charging is already fast enough, so you won't notice big difference.

Either they know nothing about electronics or they cannot calculate ^^
1. it should show 9W..... 1.8A x 5V so their meassurement device is not exact (hell, these Wallplug meassurement things are made for 220V ! so you measure 0.045A you can't expect them to be realistic, they're for up to 2000W not so low values.)
2. 9V x 1.8A = 16.2W but this is wrong again as the Quick CHarge 2.0 speccs are up to 4.5A for 9V
So if it really is charching with 9V it only uses 1.44A
Oh... and btw the Stock Sony Wall charger EP880 only has 5V 1.5A
Let's hope some people who know what they're doing are gonna test the Z2 or other phones with Quick Charge 2.0

I'm unsure about the battery but this is why QC 2.0 utilizes a higher charge voltage. Also why in computers, all high current devices now run on the 12v rail instead of 3.3v or 5v, because high amperage at low voltage would damage cables and connectors. If we had expensive graphics cards pulling 400w at 3.3v there would be a huge problem with heat and necessary wire size. There is more resistance in metals with high current / low voltage vs. high voltage / low current and this is what can damage the USB port.
This is also why at 120v AC we have issues running high current draw appliances vs 220-240v circuits.
Also why high voltage is more fatal, because it travels more easily through our skin, and etc.

I contacted Qualcomm by email, and they replied to me after a few days.
Xperia Z2 officialy does not support Quick Charger 2.0, only in JAPANESE models.
They updated their website, and removed the information, that's sad.
https://www.qualcomm.com/products/snapdragon/smartphones/sony-xperia-z2
FYI guys, Sony Brazil sells Z2 and Z3 with Smartband, so, our OEM charger has only 0.8A :crying::crying::crying:

Just purchase some charger with 5V 2A output and you will be fine..
I have tried using the standard charger 5V 1.5A if i am correct and it took around 3 hours..
And i tried using OnePlus charger 5V 2A and it is noticeably faster

I've already compared it with a normal 1.5A and it;s charging faster and the device also gets warmer.
I have a lot of apps running in the background, so my results may be other than yours.

Hello,
quick question: is it safe to charge our Z2's by S5 charger - 5,3V and 2,1A?

i dont get this. If the stock charger is 1500mA and the batery is 3200mA it should take only 2h10 to fully charge(more or less). But mine takes like 3h (brand new phone, charger and cable, all stock)

yes its 1500ma with a 3200ma battery but concider the cpu. your phone is awake for 25% of the screen being off so it should take a over 2hrs10m to charge unless you have xposed amplify installed.

OEM Charger & Cable nother Quick Charging. Phone says it is.

From my understanding when the battery is lower than 50% the Stock OEM charger is suppose to feed 9v at 1.6a. And after 50% it's supposed to drop back down to 5v 2a. My stock OEM charger and Cable does not go to 9v at all. I didn't see the charger go to 4v. Would not show amperage.

I use 3c toolboxes battery managerbut still has to be tweaked for rite readings
also if samsungs anything like lg when the screens on it don't fast charge normally to keep the heat down
like rite now my fast charge is only 1.5 amps
its always changing it might fast charge for 2 or 3 min then drop off for 2 or 3 min kind of thing
I personally don't like fast charge its hard on a battery the slower you charge em the longer they'll last
imo
just like a car battery slow charges are always better

I normally turn my phone off when I'm charging the battery because it charges so much faster and the heat and stuff. So I'll leave it off till it's done or close and take it out of the case. It doesn't take long so I don't mind doing that. I got looking into this because I was looking to purchase a new cable and wanted to be able to compare and make sure I was getting the same charge times.

Actually, I use the computer (either my desktop or one of my notebooks) to charge my devices (Galaxy Nexus , Lenovo tablet, and Galaxy S7 that is awaiting pickup by its owner). While the two Samsungs both support wireless charging (yes - the GNex does as well - as long as it is running MM or later), I prefer wired charging.

Why is that? As long as your computer supports USB 2.0 (and unless it's older than Windows Vista, it likely does) and your phone or tablet is *newer* than the Samsung Galaxy Tab 2, it's a standard feature (of both PC and phone - the same also applies to portable computers - such as laptops and notebooks). Yes - it's a trickle-charge (compared to plugging it into a wall charger or cigarette lighter) - however. I'm more than likely using my PC while the devices are plugged into unused-otherwise USB ports - it's not like the USB ports they are plugged into are doing anything else. (In short, I'm not sacrificing USB ports to use them for that purpose - out of the ten USB ports my desktop PC supports, I'm only using - for all purposes - six; I have four headers that I am not using at all.) On top of that, most USB chargers for Android devices are of the "wall-wart" type OR are cursed with short cord length - or both. (Yuck to both.)
I don't need a fast-charge - and especially not when I can top off using a trickle-charge while not using my phone OR tablet - and I'm usually not when I'm at my desktop PC.

G6 Quick charge 3.0. Is it truly quick charge ?

Hi I just wanted to know that The quick charge 3.0 claimed by LG G6 is really quick or not ? I will attach below what all I got at various timings.
Starting from Phone switched off that is 0% , I switched on the phone and let it charge and didn't use the phone at all rather than timely checking the battery charge only
28 minutes 27%
32 minutes 28%
45 minutes 42%
53 minutes 50%
60 minutes 58%
80% at 1 hr 18 minutes (Qualcomm claim to slow down after)
90% at 1 hr 31 minutes
100% full charge at 1 hr 55minutes.
Is the charger provided with the box is QC 3.0 or 2.0 ? 9v -1.8amp / 5v - 1.8amp

It doesn't matter what charger you use: LG or other certified QC 3.0 charger.

Any charger takes about 2 hours to full charge a phone. It's way too long for QC3.0

I concur.
I don't particularly want to go over old ground regarding my H870DS, but I have three QC 3.0 chargers, the charger that comes with the G6, and my QC 2.0 charger from my Z2 tablet, all of them charge my G6 at the same speed - 1% a minute. But what is more interesting, is that all of the QC 3.0 charger I have, are backward compatible, and they all charge my G5 a lot faster than my G6. 0 to 70% on the G6 takes around 1 hour 10 mins, the G5 takes 40 minutes for the same percentages. Something is clearly amiss!

Exactly this same experience. LG calls it “fast charging“: indeed it is, but it isn't QC3.
For me not a deal breaker, just my observation(s) only.

QC3 isn't any faster than QC2 the only difference is qc3 is more energy efficient which means it can change the voltage on the fly.
QC2 can't do this an excess energy is expelled as heat when the battery reaches near full capacity. QC3 can adjust the voltage to prevent this energy loss.
QC3 is likely better for the battery as it doesn't generate as much heat but it's no faster than QC 2.

It only quick charges when screen is off for whatever reason.

I thought all phones with USB Type C was QC3? I thought that was the point of USB Type C?

It officially has QC3.0

No.
By definition of the USB-C specifications QC QuickCharge is not allowed. Thats why Goolge says that they shall not include QC into their phones but USB-PD (and yes, as it seems the G6 also has PowerDelivery).
I think it is more futuree-proof to buy a charger with USB-C PD and in some jears we can use it for all kind of stuff like phones,tablets, laptops etc

Testing phase 3!!!
Well guys today I tried again back with Stock charger and Stock cable got with box.
96% at 1 hour 22 minutes. I couldn't record the 100% time due to busy time.
Main thing this time did was
NEVER TURN ON SCREEN... NOT EVEN ONE TIME IN BETWEEN.

When testing phase 2, your phone was 95% at 1h40, with testing phase 3 your phone was 96% at 1h20. No big difference when you turn screen off.

Does Quick Charge or Fast Charging support on this device?

Hey guys, I wanna buy this phone but I have question about charging, does it support quick charge or just fast charging only? Thanks

I Saw Geekyranjits very detailed Faq video.. He said it Supports only 5v/2a charger speed.. he tested it with fast charger but it charged Normally as stock charger speed ... here's the link to his video...

The phone only supports fast charging for now. The bundled charger is a 2A and 10 Watts one. It takes about 2 hour 40 minutes to charge.
But the chipset does support Qualcomm quickcharge 4.0. Yet we don't know if the board supports it. If it also supports it, maybe ASUS will enable it via an OTA update. But its very rare in such cases and if they don't release an OTA, probably you would find a supported kernel and custom ROM here.
If the board doesn't support QC 4.0, then don't worry. You won't get it anywhere. Probably, that's why there is no QC supported charger provided by ASUS.

Mine takes almost 7hours to charge. When I check using ampere it shows only 900mA max of input rate. But I think there is no any problem with my charger because it's normal when I use it to my other phone. Anyone has the same issue? I've been using any method that everyone suggest in some forum but it ended up in no change at all.

I too had same problem though mine took 5 hrs to charge . Then I found out that if all apps were closed then it only took around 3hrs to charge. Ampere app shows 1500mA .

If I turned the phone off it took almost 6 hours from 10% to fully charged. I think it's abnormal.

No need to turn off mobile , simply switch off data and wifi.

What's with this charging issue for everyone.
Also like take 5 hours to charge full battery.
2 hours only chargers from 10-45%

Charging problem
My Zenfone Max pro m1 needed 4 hours to charge from 70% to 100%....!

Mine only takes about 2 hours to go from 10% to around 80-90%. the charger first says "Charging slowly" then within 2-3 mins it will say "Charging" and then within 3-4 mins it will say "Charging Rapidly" and then it only takes about 2 hours to charge 80-90% with the bundled charger. I don't know if a better charger would increase the outcome but lets see.

My device has started supporting some kind of rapid charging

Those chargers that fully charge in 2h, can someone send us a picture os the specs?

I have a MI Quick charger,
and i use it always from the day One of using this phone,
Previously it used to take the same time as the bundled charger,
but after the last / August 2nd update, i can see some sort of quick charging working,
Because i never saw charging rapidly on the lock screen before this update,
and as per my observation, 5% - 80% takes approx 2 hrs (Quick charge way), and slows down there after,
i haven't tested with the original bundled charger after this update though,
Will share the screenshots after testing.

Fast Charging working
Yes the phone supports fast charging can see from the screenshot

The bundled charger supplied with the phone is rated 5V/2A/10W which supports QC 1.0
Asus ZMP M1 runs on SD636 which theoretically supports QC 4.0. But it is not implemented at kernel level (probably due to licensing costs payable to QC which will raise the cost of the phone)
So effectively, fast charging is not supported on stock kernel. (And I may entirely be wrong !)

Here are the screenshots,
This one with 2 hours and 34 minutes (5% - 100%) is with the Mi quick charger 3.0 charger.

And this one with the 3 hour (17% - 99%) is with the bundled charger.

Anything above 1A can be called fast charging. So 5V/2A can be called fast charging. Although it is assumed that if device supports 9V and 12V then this indicates QC level fast charging.
A more accurate comparison and result can be obtained from Ampere app. You can use any charger but the phone will draw only that much power which is supported by the board. Also,many things affect the charging time e.g. length of the charging cable, heat dissipation by the charger etc.

Please suggest me a charger bcz my stock charger is damaged.

Would you please suggest me a good fast Charger for Asus Zenfone Max Pro M1 because my stock charger is damaged and the service centre is refused to replace it because of a small crack on the charger case.
Or
Can i buy the Mi Quick charge 3.0 instead of a fast charger.? Can i charge my phone with the quick charger 3.0 safely? Is the Mi 5V 2A charger is same as the Asus stock charger? Because asus stock charger not available to buy from online. It is only available in service centre and also need to wait a while.
