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:

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:

Sorry, we don't make any fast charge power bank, but since the Zenfone 2 support fast charger, so any power bank which support fast charge will be ok.

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.

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

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?

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.

Xiaomi has recently released their new smartphone, the Redmi Note 2. This new model comes with a 5.5-inch 1080p resolution display, and is powered by a Mediatek 2.2GHz 64bit Helio X10 Octa Core cpu with 2GB of RAM,3060mAh battery; It also comes with MIUI V7 (base on Android 5.0).
The power adapter for redmi note 2 is 5V/2A, and it also comes with 3.9ft (1.2m) micro usb cable.
We have got this device for few days, and busy testing the charging performance. We test with the original chargers, the tronsmart charges (wall charger and car charger) , and also the charger which support Mediatek Pump Express Plus.
Here are some simple results base on our test:
1)Total Chagring time from battery 0% to 100% is 2 hours 10 mins with stock power adapter and stock usb cable. detail table is here:
Time Battery
11:00PM-11:10PM 0%-10%
11:10PM-11:30PM 10%-25%

2) Redmi Note 2 don’t support Qualcomm quick charge or Mediatek Pump Express fast charge, and even Xiaomi offer 5V/2A power adapter, but the max charging current is just 1.38amp, and total charging watt is lower than 10W. see the photos here:
(for reference, the Oneplus Two also have 5V/2A charger, the charging current can reach 1.9amp and total charging watt is 10W., We also use the oneplus two charger to charge on redmi note 2, same result, max charging current is just 1.38amp) .so the problem is not the charger, maybe xiaomi lock the charging current in the software? for heat? for safe? or other reason?
Here is the photo for the stock charger:
and then we test with our wall charger and car charger, here is the information:
(1) test with one port qc2.0 wall charger
(2) Test with 3-port USB wall charger:
(3) Test with dual port usb car charger:
(4) Test with 4 port usb car charger
From the above test, you can see, all of our chargers can offer same current as the original xiaomi charger.
But the redmi note 2 can’t accept more current than 1.4amp. All of our chargers’ usb port can offer 2.4Amp charging current, however, redmi note 2 just can accept 1.4amp.
So if you are looking for some back up wall charger, and new car charger for your Redmi Note 2 smartphone. Our Tronsmart Charger series should be your first choice.
Some tips about charging speed:
The charging speed is decided by three part:
(1) How much current/volt the smartphone can accept?
(2) How much current/volt the charger can offer?
(3) Which usb cables are you using?
Please make sure to use the high quality usb cables, our tronsmart usb cables are all 20awg, can delivery high current.
Any questions about Redmi Note 2 charging, feel free to contact us.

Thanks for the good review.
I assume it's not a problem at all: to prolongate capacity life it's recommended to charge at 0.5C.
Unless there's something new with li-ions, that I don't know.)
BTW, is this xiaomi using li-pol? Just curious.

Redmi Note 2 Prime
If you have a chance to test the prime version, it would be great. In any case, I will test the Redmi Prime Note 2 with your 3 port quick charger, when my phone arrives.
PS Was your test phone upgraded to the latest software release?

Yes, we plan to review the prime version, we will put more and more newest smartphone charging analysis in our channel. and yes, i have updated to the last software when i do the charing review.
Well, We just get the redmi note 2 prime version.
The accessories are the same as redmi note 2 standard version.
and we run some quick test, the charging current is also 1.38A, which is lower than 2A.

And do I read it correctly that is doesn't really matter with what you charge the Redmi Note 2 with, it's all pretty much same same mAh that goes in, right?

yes, we just test the tronsmart charger and compare with the original charger, because redmi note 2 don't support qc2.0, so the tronsmart qc2.0 charger just give it the regular charging speed, (still the same as original charger). i think xiaomi limit the current in the phone side. I am hoping it can reach real 2A current like they state in the charger, not just 1.38a.

I have been hoping for a software fix. However, I am less optimistic after rereading the listing at geekbuying. It indicates that the phone has 5v/1.4 Amp "fast" charging.

1.5 would be pretty much fast charging; the Ulefone Be Touch 2 has a fast charger at 1.5 and it loads very quickly. Too bad the tests clearly show a 1.38amp charging for the Redmi Note 2..:silly:

The real quick charge will improve the volt to 9V and total watt is 18w, the 5V/2A or 5V/1.5 can't be called quick charge. and it can't be added via software update.
and xiaomi charger clearly said it is 5V/2A charger, however, the redmi note 2 just can accept 1.5A current.
Eric
I got some different result.
First of all, my redmi note 2 behave a lot differently under different charger.
With an iPAD 12W charger, it can go as low as 500mA to 700mA (stock cable)
With original charger, it goes around 1.5A.
Most other give as low as 500mA.
The noticeable difference is the voltage. The original charger give 5.4V where the others give 2.1 will charge slowly.
But it really doesn't consistent.
There is an app called Battery Monitor from 3c71 can read the input current. It may not be as accurate as the meter but it gives meaningful reading.
It shows that my devvice's input current were cap at 1458mA
---------- Post added at 01:42 AM ---------- Previous post was at 01:40 AM ----------
my wrong....... just did another test..
the widget shows +1925mA
And my Electric Meter showing 0.057A under 220V lol... with ipad adaptor and ... docomo cable.
i think we can modify this modifying some file, because exists some kernels with "ampers charge" modified at 2A
But... where is the file.... ?
I have noticed that even when GSam (app) and Ampere are telling me that it is charging at around 1.5A, it doesn't actually charge that fast. For example, GSam also told me it would take over 4 hours to charge to capacity. Now if it is really charge at 1.5A, and the battery is 3A, it should take two hours, no?
I use the original charger and it charges much faster, however this is not convenient for me.
I even have this special hub and charging cables: http://www.amazon.com/EasyAcc®-Char...8&qid=1442288174&sr=1-15&keywords=easyacc+hub
I tried the Samsung Galaxy Note 4 quick charger on my ZE550KL 2GB ram model. The starting battery percent was 18% and after about half an hour the battery was still at 42%. I read on Qualcomm's website that SD410 supports quick charging 2.0. But the results speak otherwise. Could it be the software restricting quick charge?

The processor supports quick charge, but as far as I know, it's not implemented in the phone.
Yes I tried it too recently and the best rate at which phone charging was 1.1A (I used 2.1A charger, it took 3 hrs to charge from 10% to 100%)
Either we should all ask ASUS to enable fast charging in coming updates or wait for someone to build custom kernel that supports fast charging.
if it's any consolation, the moto g3 also doesn't supports quick charging. It also has SD 410. 3 hours is the time is takes for me to charge it to full with the provided OEM charger as well.

I had Moto G 2015 for couple of weeks. Didn't really use wall charger enough, I used USB charging through PC most of the times so can't really say about charging time.
I found some references online they claimed Moto g3 does charge faster, here is one...
http://forum.xda-developers.com/2015-moto-g/help/charge-time-t3171725
As far as the laser is concerned, has anyone raised this issue with them on forums?
can't bear slow charging :crying:
It more than likely has to do with the USB configuration so I doubt any software update will enable that, but to be fair it could be a software based limitation. The USB component needs to allow for the high throughput though.
I personally don't feel too negative about the charge time because I came from an iPhone 5S that doesn't have quickcharging. I am sure for others it is like watching paint dry though.
What I find most disturbing about the phone is that, it came with a 1A charger. You can save some significant charging time if yo use a standard 2A charger.

Have you tested this? Devices will only pull what they are able from a charger so if it was designed to drawl up to 1.35A then even with a 2A charger it will only drawl 1.35A.

I think you are right on this. I just tested and even with a 2A charger it takes more than 3 hours to charge the phone.
Anyone tried using qualcomm 2.0 certified quick chargers?
From this zentalk link, looks like my suspicion was correct. Event though SD 410 supports quickcharge, Asus limited the circuits etc. to not take 2A. Sad!
At least it charges faster on super saving mode.
35% in 60 mins on Normal mode
41% in 60 mins on super saving mode

My ZE601KL comes with a 2A charger in the box. I would say it charges quick when battery is real low and slows down when it close to 80% to complete the rest of the charging cycle.

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

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.

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

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.

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.

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.

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.
