I bought a few QC2.0 chargers for my AT&T G4:
2-pack Samsung Adaptive Fast Charge AC chargers: .walmart.com/ip/45734981
Tronsmart Dual Car charger: .ebay.com/itm/191645992162
Aliexpress knock-off single QC2.0 car charger: .aliexpress.com/item/Qualcomm-Quick-Charge-2-0-Stand-USB-QC2-0-Car-Charger-for-Samsung-Galaxy-S6-HTC/32364542508.html
..... and compared with the performance of the STOCK LG G4 1.8 Amp (non-QC2.0) charger.
[Note: front end of URLs ( h tt p : w w w.....) left off since newbies like me can not post external links]
I charged my G4 with power OFF, and used Battery Monitor Widget
( play.google.com/store/apps/details?id=ccc71.bmw )
to measure before and after % remaining,
I "generally" began the charge cycle when the %remaining was low (3-16%, 11% average)
and charged for about an hour (52 minute average)
For each I repeated the test 2-3 times.
Here are the results:
Stock Charger: 1.033 avg, 1.04 max % per minute
Samsung: 1.249 avg, 1.300 max % per minute
Tronsmart: 1.248 avg, 1.290 max % per minute
AliExpress: 1.221 avg, 1.270 max % per minute
So.... even though QC2.0 CLAIMS to charge up to 75% faster, my results were closer to 25% faster
All the QC2.0 chargers were rather consistent in their performance.
I found ambient temperature was an important factor.
The 1st test with the AliExpress was done in a closed car on a 110F day (without AC on)
I got 0.25%/min - but disqualified this result due to the temp extreme
(All other car charger tests were done with car running while driving with AC on)
I'd be interested in seeing if anyone else can test their chargers similarly and post the results here.
I thought QC chargers only quick charged QC compatible devices?
G4
And G4 is QC2.0 compatible, isn't it?

They do. The Qualcomm website claims that G4 is QC 2.0.

I would think testing closer to 70° would be wiser.
I get this spike using my 2.0 charger, it never stays that high for longer than 10seconds.

Que QC 2.0 on the G4 is a joke, it barely doesn't even exist.
I can't even use my quickcharge 2.0 charger. Anyone know why that may be the case? I'm on software version G, the charger works perfectly fine with my note 4 for quick charge but not on the G4... It's a GETWOW qualcomm quick charge 2.0 charger

Your battery is 90% full, is it any different if your battery is lower, like 10%?
My Keedox qc 2.0 is charging my g4 faster than my ex-m9! It can fully charge from 45 to 100% in 30 mins only, it was 50 mins with the m9!!!
No complaints from my Quick Charger
Ive got the uk plug aukey single port quick charge 2.0. Did a timed charge last night 14->48% 25minutes (1.36%/minute), 48->71% 16 minutes (1.44%/minute), 71->92% 19minutes (1.11%/minute) - total time from 14% to 92% one hour (1.3%/min) so about the same as OP test.
With custom kernel we should be able to reach much higher charging rates...on g2 with dorimanx kernel i never saw anything below 1600 and got up to 21xx

Agree. I use aukey QC 2.0 3 port. Using QC 2.0 port, or just the same charging time using stock charger. From 5%-100%, both need time about 105 minute. No different. I sold my aukey.
Aukey using 9v (8.9v exactly) and 5v for stock charging.

Hello everyone,
Ever since I got this Mi5 (125GB 4GB version) I've been trying everything I can so see it its behavior matches what is advertised. I should start off by saying so far so good.
Coming from a Moto X xt1092 I was used to some sort of indication that I was plugged to a QC enabled charger, not just a regular one. On this Mi5, however, and keep in mind that I'm under Lineage OS, I have no indication. I can count the minutes it takes to fill up a dead battery or maybe just 50% percent of it, but I'd like a sure and bullet proof indication. Also keep in mind that I'm using the original charger and cable - said charger that has the QC symbol on it.
Reading other threads, I noticed some posters were advised apps like Ampere - which I installed. Now, what kind of values should I expect from the app when charging? As of now, it hits a maximum of 1610 mA. What should I be looking at and what are the cutoffs above which I can be sure it's quick charging, as opposed to just regular charging?
Thank you in advance.
Added info: just set it to charge at 4%. 38 min later it was at 29%. It seems to me that 25% in 38 min is below QC 3 or even 2 standard (as it is often said that despite the mi5 being QC3 compatible, the original charger is QC2).
So, any chance one of you mi 5 owners can grab that app and give me some reference numbers? Just so I know for sure that I need to try and get a refund for the charger the phone shipped with.
4.1260 V
2860 mA
Edit
Miui 8.2 by xiaomi.eu
7.2.9 beta weekly

Thank you.
Yeah that's way higher higher than what I'm getting. Also, under technology I have "Li-ion", and a much lower Voltage.
Weird.
Something is definitely up.

the brick you get in the box is qc2. The device supports qc3 though and if the device is hot it will go upto 1610ma only buy a qc 3 brick roughly your charge should be done in 1hr 15-1hr 30 minutes
I knew the charger was qc2, I just thought it would go higher than 1610, which is exactly the top mA registered. Thanks for that info - I guess there's nothing wrong with it.
I have a qc3 charger on the way too.
The shipped charger has max current of 2.5A and indeed, during the first 10% ampere shows value near that (23XX mA on my phone). It will then gradually decrease down to 0.01A when the capacity is above 95%. Using real QC 3.0 charger (I have both Tronsmart and Aukey), the first 10% it can reach 28XX mA. The ending is similar, though.
I use the stock charger and cable that came in the box. I bought it here in macedonia. But i dont have an idea for wich market it is destined. I can confirm that it charges the phone to 85-90% in less than an hour, then it gets slow as stated above
Yeah I don't get those times, not even nearly. As you can see from the screen shot it took about two hours, most of which with screen off and no activity.
Do you have the same oem charger that i pictured above?
try to use different cable or different charger like aukey or tronsmart..
FYI original charger which support QC 3.0 Just MDY 08-EH

No only mainland china mi5 ships with QC 3 other regions where mi5 is sold only gets qc2 charger Google it if you want
Well mine was bought in Macedonia (south east europe) and i got a qc 3.0. indeed it is not with a local standard socket so i use a smalla dapter for the plug, but the point is that it depends to wich parts of the world xiaomi "officially" export, and to wich parts of the worlds (most of them) local companies undertake an adventure to import a batch of several hundred or thousands units from xiaomi, thus meaning destined for local chinese market

Yes, the exact same. But as that's not an European plug, I wonder if that's why I get different performance - it came with an adaptor.
I'm awaiting a new cable and charger in the mail soon that should clear it up.

Damn.
This is original charger and cable? Any US to EU adapter by any chance?
Here's hoping it's not lineage os related.

It's stock charger bro.
Using the stock charger, a qc2.0 one (given with the international version of MI5), I get about 2200ma - 2300ma. I haven't tried a quick charger 3.0. However, check your kernel as well. The stock one of Lineage OS have an issue with quick charging, working once only after boot. I use DragonXia kernel and the qc works all the time.
To check if it is kernel issue, shutdown your phone and them connect the charger. I will start charging but using the recovery/boot kernel based on marshmallow, which (at least for me) hasn't got the issue of qc. Observe then the speed of charge and report.

Tested a mi5, same variant as mine, just today, with same lineage OS version. Also original charger and cable. Values are the same as yours, well above mine.
However, my original cable is defective, and has been refunded as the phone wasn't being recognized on the pc (which was a problem when flashing roms). A new one is in the mail, and in a day or two I suspect it'll solve the issue. I'll let you know.
Keep in mind apps are a bad way to check for QC capability.
My xiaomi stock charger puts out 1,8A @ 6V with 70% full battery(the higest current is being used between 20-50%, i'll try that later on)
Ampere only shows battery voltage(3,7-4,2V) instead of charging voltage and the ampere display is way off actual current
I have recently purchased the Mi Mix with the Chinese ROM, I have now unlocked the bootloader and flashed the most current global ROM, I believe the Mi MIx is quick charge 3.0 according to specs on Qualcomm and Xiaomi website. I have tried the LG g5 quick charge plug and the Anker quick charge 3.0 powerport +1 and neither of them display fast or quick charging, it definitely isn't quick charging as it takes nearly 5 hours to charge. Any help or info would be appreciated as it's driving me crazy, I understand it's a much bigger battery but surely 5 hours for a brand new phone isn't fast charging, could this be the kernel or global ROM isn't supported. Thank you to anyone that me be able to help in any way.
Ok?

I don't understand why it would take that long, the question would be from what % are you changing, my mix takes a little more than an hour to go from 45% to 100, and a little bit more than two hours from 5% with the changer that it came with, remember not all phones are created equal also I'm on epic rom 7.3.30
Battery is 4000 mAh then to charge you have to wait a bit... with a quick charge 3, i have 1h45 to fully charge my device...
Try another usb cable
Ok, I changed the cable and plug, charging from 0-100% in just under 2 hours, fairly quick but should it show on the lock screen as fast charging as mine shows just charging.
I'm using Ampere app (https://play.google.com/store/apps/details?id=com.gombosdev.ampere). On original charger it shows max possible current 1800 mA, and after some crazy readings it stabilizes indeed around of that value. Other my chargers are not so good. You have to wait a bit (minute?) until the reading will be accurate. First readings are crazy high.
Other such apps probably work as well.
ampere give u right speed amperage value.... value decrease with higher battery level, you are not full mA all the time.... if somedody use a custom kernel like papashclumpf... try to ask a way to fully charge all the ime... i suppose kernel can manage this !

Under 2 hours should be quick charging.
i agree
Hello,
i've bought a Xiaomi Charger Set ( amazon.es) to use the 27W charger for faster wired charging.
So i'm pretty sure it is original and it says Turbo charging on lockscreen..
It charges with up to ~4000mAh when i just plugged it in, but drops after a few minutes to common "QC3 currents".
I stopped the time with the boxed QC3 charger from 11% to 75% and with the QC4+ (27W) charger from 11% to 75% and it was not a minute faster (same with a QC4+ Belkin Car Charger).
Did you stop the time and checked if it actually charged faster for you?
Yes its way faster than 18w charger
Dont relay on ampere app its not real
I have also tested my 27w charger, even posted pics on another thread, and it does charge faster. Also, I don't think I'm going crazy when I say this, but my battery seems to last noticeably longer.
Maybe this could just be a placebo or because I updated to 9.8.1 since then.
To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the Xiaomi Poco F2 Pro (Redmi K30 Pro) can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!
With the supplied charger and cable the charging time is very impressive ("Turbo Charge") with a normal QC3.0 charger charge time is still very good but comparable to most other QC3.0 devices.
Something to note is the device does get noticeably warm when using the supplied charger in the "Turbo Charge" mode.
Takes about an hour for me with included charger.

yes i noticed it get warm to hot-ish
isn't that bad for the battery?
moreover i noticed that if you charge while turned off it does not get hot

That's normal because you're not using it, if using while charging it will be hot as your running apps, tasks etc... at the same time. This will increase the heat as sensors will be running also.
Has anyone tried to use other cables that has the same turbo charge effect like the included cable? The included cable is too short, usually I use 2 meters long cable.
I have tried the baseus 5A 40W cable but it only support quick charging and not turbo.
I've tested charging wattage using original 33W charger and original USB cable via specialized USB tester, and I noticed it provides only 25W (about 9.6V/2.65A). It shows "Turbo Charge" indeed, but it's still only 75% efficient. Anyone care to explain this? Is this normal? I've read that only Zoom edition can be charged at 33W, so I expected non-Zoom edition will charge at least with 30W. I tried two other USB cables, and still only 25W. Later today I will try to charge it with Blitzwolf 30W PD charger and see how it goes with that one...
I haven't really tested charge speeds. So far the battery life has been exceptional and the main reason I opted for this phone without the high res screen and refresh rate, as see battery as more essential. I would much prefer charging at a slow speed to preserve battery life. A good app for this is AccuBattery. It measures how many mAh's being charged and discharged after each charge and keeps a graph. It will estimate battery health also.
Yeah I know about AccuBattery, I've been using it in the past. But a real physical tester device is always more precise. I do sw/hw development for a living so I know for a fact. Indeed, battery life is very good because optimized MIUI and pretty big battery, but it would be even better if charging speed was also up to the specs. Meanwhile I've tested charging speed using Blitzwolf 30W PD2.0 charger (K30Pro should support PD3.0 and be backward compatible), and situation is even worse - only about 15-16W at QC3.0 I believe. So no Turbo Charge was initiated. I mean 25W with original charger is still good, but I expected advertised charging speed. I'll do more tests when I catch some time.
Thats normal, because it don't charge all the time with 30W. Compare it with WARP Charge 30T it is faster. OnePlus 8 got 30W and 4300 mAh, F2 Pro is faster with bigger bettery but it's almost the same.
How old is your Blitzwolf charger?
I know it shouldn't charge @30W above 80-90%, but sure it should at 20-ish where I'm at about now. It's also not even cool to the touch, so there's no apparent reason to slow it to 25W. My Blitzwolf charger is about a year old, but I only used it couple of times, so it should be as good as new.

Batteries don't like heat but it is actively monitored and it will slow down charging when it crosses temperature threshold.
That's why I mentioned my phone is not even cool to the touch (let alone hot), so my case is not temperature related. I'll try to charge it while turned off, though it was pretty much in idle doing nothing when I did the test, ie. not stressed at all by any factor. All in all, I mean if everyone else gets 25W out of original charger, I won't bother anymore. Also, if it charges from 10-90% in around 1 hour, I won't waste any more time on this either, since it's good enough for me. I was just curious why it charges at 25W, when 30W (and 33W for Zoom edition) was advertised. Altough it wouldn't be the first time something was advertised at launch, and not achievable in real-case scenario.

Fun fact: phone doesn't charge when powered off?! That's a first. Is it just me, or am I getting too old? For the whole time I'm talking about my Redmi, not to confuse it with Poco, if that matters at all. Maybe Poco works differently.
On my Huawei device you also can not turn off an charge but this starts with Android 10.
takes about 1 hour and 20 minutes for me, I think the high temperature here, summer season, is the reason for this slow charging speed.
From 20-100% in about an hour. Few minutes less actually. Battery is big, that's all ok.
F2 turn off and are dead with 0% (can't turn on). Timer 60 min. and after 60 min. I got 96% with original charger. The phone don't turn on, like it always do.
@Burs a friend told me "on my Anker charger I only can use PD over the third usb port, with the type c port it will charge over QC 3.0 and not over PD" maybe thats why you get ~16W?
When my Redmi was turned off completey, it was hooked up to my USB tester for about a minute. I doubt it would trigger after some minutes, and only then start charging. For the whole time it was connected, I was getting 5V / 0.015A readings on the display. That's pretty much USB tester drawing the power from the phone battery, not the charger! So that would mean charging was completely disabled making the phone behave as a power bank lol. Weird enough, right?
My Blitzwolf charger has only two ports. One PD2.0 (USB-C) and one QC3.0 (USB-A). I've tried three sets of USB cables (one even 5A) on both ports, and best I could get out of it was about 15W. I think I'll have to order another one with PD3.0 and Turbo Charge compatibility.
Heh I'm planning on just using my old 1A slow chargers because they're dotted around the house and work, will probably not even plug fast charger in. Magnetic cables are just so convenient.
