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.

He doesn't know what he is saying...! Note 3 comes with 3Amp charger because its NOTE --》3《-- !!! Note 2 had 2 Amp charger and next year note 4 will have 4! Amp charger....

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
after the device reaches 100% charge?

What do you mean reverse?

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.

Zenfone 2 (ZE551ML) Charging Analysis

HI Guys
Today we will do a charging analysis for Zenfone 2, Model: ZE551ML.
Zenfone 2 has a 3000 mAh Li-Polymer battery and support boostmaster technology, which is compatible with quick charge 2.0. and Qualcomm also list Zenfone 2 as supported device in their official site.
The model we test is ZE551ML, 4G/32G, We are surprising to see ASUS don’t include the fast charger in this model, just regular charger, here is the photo:
{

"lightbox_next": "Next",

"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
The standard charger just can offer 5.2V/ 1.35A. and ASUS includes a short usb cable ( about 0.9cm length) , see here:
and we test the no-load volt for the stock charger, see here:
Now we begin to test the total charging time with stock 5.2V/1.35A power adapter and usb cable. We have made our Zenfone 2 battery to 0% and here is the test result:
Time Battery level Volt Current
PM 1:34:00 0 4.9V 1.13A
PM 1:44:00 Battery is low, can’t power on to show the battery level
PM 1:54:00
PM 2:04:00
PM 2:14:00 23% 4.9V 1.13A
PM 2:24:00 29% 4.92V 1.12A
PM 2:34:00 36% 4.92V 1.12A
PM 2:44:00 43% 4.92V 1.1A
PM 2:54:00 49% 4.92V 1.1A
PM 3:04:00 55% 4.92V 1.1A
PM 3:14:00 61% 4.92V 1.1A
PM 3:24:00 68% 4.92V 1.1A
PM 3:34:00 74% 4.92V 1.1A
PM 3:44:00 80% 4.93V 1.03A
PM 3:54:00 86% 4.97V 0.8A
PM 4:04:00 90% 4.97V 0.75A-0.55A
PM 4:14:00 94% 5.02V 0.38A
PM 4:24:00 97% 5.02V 0.32A
PM 4:34:00 99% 5.04V 0.2A
PM 4:41:00 100% 5.08V 0.16A
The total charging time is 3 hours 7 mins with regular charger, and you just can get 20% battery in 30 mins (PS: we found an interested thing, the zenfone 2 can’t be powered on if the battery is lower than 20%, i am not sure if it is my phone problem or you guys also have this problem?). After charging for 1 hour, we just get 36% battery, charging 2 hours, we get 68% battery, charging 3 hours, the battery is almost full. The Charging current will become smaller as the battery growing. but max, you just get 1.13A. Here is a photo we take when we test:
Frankly speaking, If we don’t test with quick charge 2.0 chargers, we might think the charging speed is OK, Most people might think they just leave the phone to charge overnight, and if it can charge full during the sleep, then it is ok. However, if you tried with quick charge 2.0 chargers, i thought you should change your mind.
Now we begin to test with our chargers and cable:
Test with Tronsmart WC1Q wall charger (Qualcomm Certified, support quick charge 2.0), and Tronsmart USB cable (20AWG support high current):
Time Battery level Volt Current
AM 8:45:00 0% 9.15V 1.65A-1.56A
AM 8:55:00 Battery is low, can’t power on to show the battery level
AM 9:05:00 27% 9.15V 1.5A
AM 9:15:00 43% 9.15V 1.5A
AM 9:25:00 54% 9.16V 1.32A
AM 9:35:00 68% 9.19V 1A
AM 9:45:00 77% 9.19V 0.87A
AM 9:55:00 84% 9.2V 0.62A
AM 10:05:00 88% 9.22V 0.39A
AM 10:15:00 92% 9.23V 0.28A
AM 10:25:00 95% 9.23V 0.17A
AM 10:35:00 98% 9.23V 0.16A
AM 10:45:00 100% 9.23V 0.14A
With our chargers and cable, we get zenfone 2 from 0% to 100% in 2 hours, When it detects Zenfone 2 support quick charge 2.0, our charger just give 9V volt instead of 5V. and you get 54% battery in the first 40 mins, and in 1 hour, you get 77% battery. (while with stock standard charger, in the same time, you just get half battery). Our chargers can give 15W power to zenfone 2 at first, while the regular charger just can give 5W. That’s a big difference. We also can see in the above table, while use our charger,in the whole charging progress, Zenfone 2 always get 9V high volt , but the charging current is becoming smaller as the battery growing.
We take a photo after charging a while with our charger to show the quick charge:
So from the above testing, we can see, use our quick charge 2.0 charger, you can save 36% total charging time , it can offer double battery level at the first 1 hour compare with regular charger. Like Qualcomm said, Less time charging, More time doing. And not just our wall charger, our quick charge 2.0 car charger also support Zenfone 2, you can get similar charging time when you use our quick charge 2.0 chargers.
In the end, Here is our suggestion to charge your Zenfone 2 faster:
1 If your zenfone 2 don’t equipped with a fast charger, just get one asap
2 Pick up some high quality usb cables, it do effect the charging, i take a photo to compare our usb cable and asus one:

2. but Qualcomm lists only Zenfone 2 selfie, ASUS Padfone X which as Qualcomm processor and Both phone don't have Quick charging feature.
3. Qualcomm Quick charge 2.0 is a name of second generation fast charging tecnology present in the Qualcomm processor, They are the first processor company had this feature. Quick charge 2.0 is a copyrighted name of Qualcomm, for marketing and brand recognition name
4. Intel processor had fast charging first time in zenfone 2 and it named as " BOOST MASTER TECNOLOGY " and its a first generation, So its version 1.0 . Intel need to focus on the marketing for get the brand recognition of their technology aganist Qualcomm.

currently there is no charger certified for Boost master technology ( intel's fast charging technology copyrighted brand name ).
But U can use any charger with 9V output.

I have the Aukey from Amazon, it is QC2.0 certified

Thanks for your reply. The reason i thought zenfone 2 support quick charge 2.0 technology is Qualcomm list them in their site, see here:
https://www.qualcomm.com/documents/quick-charge-device-list
In our understanding, quick charge 2.0 is not locked to qualcomm soc, they hope the other soc like intel or samsung to use their quick charge technology. We can see, samsung call themselves "fast charge" , and Motorola call themselves "Turbo Charge" , but in the end , they are the same as qualcomm quick charge 2.0. In qualcomm base smartphone, the soc, the PMU, the charger make the quick charge happen, in other SOC base smartphone, they use software to control the watt.
Intel might want to built its own quick charge technology, samsung also want, however, we have to admit , Qualcomm has the best quick charge technology right now. a lot of smartphone support this technology, and they even announce the quick charge 3.0 some days ago. check here.
So ASUS boost master technology can compatible with quick charge 2.0, it is a good thing.

My phone came with 9v 2a charger out of the box.

Yes, that's normal. ASUS have different marketing skill for different market, they don't equip the quick charger in china market, but ask people to buy separate.
By the way, can you go back to normal charger once you use the quick charger?
and do you use any qc2.0 device in your car?

1: yes normal charger works. Why not?
2: Don't have qc for car. So never tried.

Works in the car

2. but Qualcomm lists only Zenfone 2 selfie, ASUS Padfone X which as Qualcomm processor and Both phone don't have Quick charging feature.
3. Qualcomm Quick charge 2.0 is a name of second generation fast charging tecnology present in the Qualcomm processor, They are the first processor company had this feature. Quick charge 2.0 is a copyrighted name of Qualcomm, for marketing and brand recognition name

what are you talking about, the teardown of this phone shows that there's a separate IC for quick charge
http://www.asus-zenfone.com/2015/05/asus-zenfone-2-disassembly.html
SMB1357 is just qualcomm's off-die separate package IC for quick charging 2.0.
https://chipworks.secure.force.com/...u=QUA-SMB1357&viewState=DetailView&cartID=&g=
intel so far has no officially disclosed quick charge technology so Idk where you are getting all these info from. zf2 is compatible w/ all quick chargers because it has the necessary IC for QC2.0, otherwise it's not gonna pull more than 10W

Is there any custom rom to remove this limit? 1.1A is super slow.

I've been using this phone for past 3 weeks and I'd say that to charge phone this phone with official Asus normal charger takes around 2 hours and 40 minutes and takes same with power bank.

WW version with 2.0A charger. It takes a bit more than an hour to fully charge.

Do you use the qc2.0 charger or regular charger?

Don't know wich charger i have, my phone is ze551ml ww. But i noticed that after august update take too long for full charge. Sometime i charged phone with PC usb port, adb was always on so if before was taken 20m to full gain charge starting fro 65/70%. Now it take more then 30m, but is not the only thing i noticed, with stock charger seem qc is gone, another thing is, if you unistall clean master take very long too full charge, tryed other app like duBattery but not helped to reduce charging time. Well i will try asus fast charge, from my asus mobo and asus native software (only 1 usb port on the back pannel used for winOS poupose) but i think will take the same time 'cause no fastcharge support from zenui and i don't know how will safe for battery life if there's no support for overcharge, i mean no maintenance and optimitation charge.

Regular Asus charger if I turn off it then it takes 2 hours

[QOTE/]The model we test is ZE551ML, 4G/32G, We are surprising to see ASUS don’t include the fast charger in this model, just regular charger, here is the photo:[/QUOTE]
EU retail ze551ml is 5v.2A/9v.2A but no difference, asus AI Charge+ not recognize device like asus but like othrs, charging time too long anyway then before august battery patch. Tested with asus cable and others (even with ota usb cable with solenoid).
Can you retest without clean master runnig or was with turned off phone?

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.

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.

Charging speed

To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the Realme 3 Pro can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!

Very good
One of the very few things that are good out of the box about this phone. Charges from 10 to 100% in 75 minutes even with screen usage while doing so.

Same here. If I want to go out and the battery is around 40%, I just plug the charger for a while. By the time I'm ready to go 15-20 minutes later, it's already around 70%. Thats more than enough juice for 9to5 office hours.

Realme 3 pro uses it's own VOOC 3.0 fast charger right? And it use snapdragon 710 that support Qualcomm quick charge 4.0
But Can realme 3 pro use qc 4.0 or even 3.0 atleast, like qc 3.0 powerbank or car charger maybe? They don't really have vooc accessories don't they? Just usual vooc charger?
Edit: I've found 6000mah vooc powerbank made by oppo itself, but the price is like 3 or 5 times more expensive than usual 10.000mah qc 3.0 powerbank price in here, insane ? i don't wanna pay that much for powerbank, so please still looking forward to see the compatibility between realme 3 pro and quick charge 4.0 or 3.0
Thanks

Charging time for me :
30 min - 0 to 44%
1 hr 25 min - 0 to 100%

I lost the original cable. I can't find a authentic vooc 3 cable anywhere. Please help. Without that particular 7 pin cable, it's 5 v 1 amp instead of 5 v 5 amp.

Edit: i've try to search any info/video about the compatibility, and it's looks like realme 3 pro does not compatible with quick charge 3.0 (it will only be a normal charging if using qc 3.0). Still looking for qc 4.0 compatibility, but still not found one. About vooc powerbank, i came across with 2 other powerbank (both 10.000mah btw), not made by oppo, that support vooc charge for realme 3 pro. Unfortunately, it appears that it only available in my country. I've try to search it in banggood or amazon, but it didn't available. In theory, if the chip support qc 4.0 it should be compatible. But then again, what do i know. Peace

VOOC is a Proprietary technology of Oppo, Other brands won't have it even if they advertise as one. Beware.
