In Xiaomi mi 4 quick charge2.0 not enabled

Seems Qualcomm which charge 2.0 not working with Mi 4 original cable anyone suggest how enable fast charging on Xiaomi mi 4.

If I'm not mistaken, you need a charger with higher outputs then the standard wall charger shipped with most phones. Just a guess though seeing as my Xiaomi Mi 4 charger is a five volt charger.

My charger say Output 5v=2A/9v=1.2A/12v=1A i dont know if that whats needed but it charges very quickly.

5v is the voltage standard. What you want is AMPS. ALWAYS select 5 volts.
Computers (USB 2.0) can output maximum 0.5A (500ma) at 5 volts, while USB 3.0 can output 900ma or 0.9A.
Most MicroUSB chargers output anything from 1A to 3A+, with 1A and 2.1A being the most common.
So while a 1A will charge your phone a X percent per minute, a two amp charger will charge it at almost double the rate (not exactly, but close enough).
I do however (and I stand corrected), recommend not to go too high an amperage, while your phone my not get damaged, slow and steady charging is better for the battery than high current, quick charging.
Some phone, like my Galaxy S5, requires a 2A charger, but other phones may not like it.

I think it's always enable ...

Power bank

Is this power bank compatible for the galaxy s7 ? Plz i need help
Romoss PowerBank Sense 6P PH80 20000 mAh - Blanc

Yes for normal charging, not for fast charge

Yeah i know for normal charging but i want to know if using this power bank take too much time to charge my device ?

That's not what you asked, you asked if it was compatible with your S7
It should take the same length of time to charge as the stock charger, it has 5v 2.1A, stock charger is 5v 2.0A

Yeah exactly that's what i mean thank you

Best Charger for Zenfone Max Pro M1. (Stock Rom and Kernel without root)

Suggestions for best charger.

Our stock charger is good, its only the usb cable that is bad, first try with a different cable and stock adapter and see what speed you get. Also keep the temp of your phone down, if it reaches above 42 you'll get slow charging.
And suggestions for chargers that I've personally used are mi 2A adapter and samsung adaptive fast charger which is also a 2A charger.
The cable i use is amkette 3A cable.

I use LCARE charger that I bought from Amazon. It is QuickCharge compliant. Charges the device from 0% to max in 2 hours and 5 minutes for me. It's the model with 2 high speed ports and one regular 2.0 amp port.
I bought it for approx 500 rupees.

Poco F2 Pro Charging Study - How Fast does it charge?

Hello
So a couple of weeks back I upgraded to the Poco F2 Pro 6/128GB from my Mi 9T.
I have been using a magnetic charging cable with my Mi 9T, with a little magnetic part permanently in the usb port for convenience with a standard QC3.0 charger. Worked great and charged fast at 18W.
I wanted a similar solution for my Poco F2 Pro.
So I have done some testing and the results might surprise you.
Poco supports 30W Mi Turbo Charge which seems to be a custom Xiaomi charging protocol and does not seem to play nice with standard USB PD3.0 Protocol.
I have done charging tests from ~5-20% battery for maximum charging speeds and tested the actual charge rates with a USB Voltmeter
Voltmeter:
https://www.ebay.co.uk/itm/USB-Mete...e=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2648
Test 1: Original Charger and Cable
Result: 30W Mi Rapid Charging (~9.6V, 3.1A) As Expected
Even tho the original charger is rated at Max 33W, Poco only charges at 30W Max.
Test 2: 60W USB PD3.0 Charger + 5A Type C to Type C Cable
Charger: https://www.amazon.co.uk/gp/product/B0824S38VC/ref=ppx_yo_dt_b_asin_image_o07_s00?ie=UTF8&psc=1
Cable: https://www.amazon.co.uk/gp/product/B07QPNRGYH/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1
Result: 18W Standard Fast Charging (~9.2V, 1.9A)
I did multiple tests to check if the charger is legit (which it is, many of my friends use it with different devices and it works great) with my brothers Pixel 4XL, and my friend Xiaomi Mi 9.
Pixel Charged at 18W, Mi 9 at 27W.
The phone did not charge at 27W (~9V 3A), even to it does support PD 3.0 charging.
Test 3: Original Charger with a 3A Ugreen Magnetic Cable
Cable: https://www.ebay.co.uk/itm/Ugreen-M...e=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2648
Result: ~25W Mi Turbo Charging (~9.6V, 2.6A)
This is very interesting since it does trigger the Mi Turbo Charge, it is not the full speed charge like with the original setup.
Original setup also has a charging animation, with the % increasing at a steady speed.
With the Ugreen Cable, there was no animation.
Test 4: Original Charger + 40W Huawei Supercharge Cable
Cable: https://www.amazon.co.uk/gp/product/B08CR7W2T1/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1
Result: ~25W Mi Turbo Charging (~9.6V, 2.6A)
The original Xiaomi Cable is a 5A Cable, so I thought id try a Huawei Supercharge Cable, but it ended up charging the same as a 3A Ugreen Cable
Test 5: 60W USB PD3.0 Charger + 5A Magnetic Type C to Type C Cable
Charger: https://www.amazon.co.uk/gp/product/B0824S38VC/ref=ppx_yo_dt_b_asin_image_o07_s00?ie=UTF8&psc=1
Cable: https://www.amazon.co.uk/gp/product/B08HLN27DP/ref=ppx_yo_dt_b_asin_title_o04_s00?ie=UTF8&psc=1
Result: 18W Standard Fast Charging (~9.2V, 1.9A)
Again, standard 18W fast charging, not 27W as you would expect.
Conclusion:
From my testing, the only way to charge the Poco at Maximum speed of 30W is with the charger and cable which I find very strange. Does the original Xiaomi cable have a custom Xiaomi chip which handshakes with the charger to get the full 30W Mi Turbo charge?
With a PD3.0 Charger, I was only able to achieve 18W of fast charging, again very strange, since Poco should support 27W (~9V 3A) charging with any PD3.0 Charger.
I have settled for a setup with the Ugreen Magnetic Cable and the Original Charger for convenience, ease of use and preventing the USB port from being worn out. I am loosing about 5W of speed, which does slightly increase the charging time. (I charge my phone to ~85% max)
(If there is something wrong with my methodology let me know and I will re-test if needed)

I approved with an Aukey 29w Fast Charging charger (model pa-y7) and the same charge at 18W, even with the type-c cable on both sides (Baseus brand cable up to 60W)

It seems like Xiaomi cable and charger have an extra pin. That might trigger and power the turbocharge

I don't know at which rate it charges but it triggers Charge turbo animation with the % increasing at a steady speed with almost any proper USB-C to USB-C cable.
I've also found that if you launch the CIT on the phone by tapping on kernel version 3 times on settings->About this phone->All specs
and go to the charging test (number 24) you can check which protocol is being used
If you use any QC3.0 charger it says USB_HVDCP, which triggers fast charging but not the charge turbo animation.
If you use a regular PD charger it says USB_PD which also triggers fast chargingbut also not the charge turbo animation.
If you use the original setup it also says USB_PD which means that extra pin it has on the USB-A connector is wired in a weird way it actually negotiates usb PD protocol, which I can also confirm because I connected it to a Thinkpad T480 and with the Lenovo Vantage software gets 27W charging, which is not possible with any USB-A to USB-C cable and QC3.0 charger.
Which may mean that maybe Xiaomi didn't want to pay for the QC4.0+ chipsets or something and did some weird stuff to get PD through QC3.0 by that pin and through the F2s software reducing the cost of the charger in the box and whatever else. As for this GaN 65W charger I have no idea on how they pull that off but is a proper PD charger

Since the update to Android 11, a set of cables that previously triggered the Turbo Charge, now suddenly work only as Fast Charge.
They were a bit slower than original before, but now they are a lot slower.
I only have the Accubattery measurements:
cca 4000 mA average on Android 10,
cca 3000 mA average on Android 11.
While the original charger + cable shows about 4500-5000 mA average.
They really managed to screw this device.

On ArrowOS my device charging at 1.8A and 7.5V with original charger and wire... so it depends on software. But anyway I don't want to downgrade from perfect OS to buggy MIUI only because of that.

I also have seen a weird change in charge speeds..
Used to be totally fine but it seems that for a while now the speeds are very slow and quickcharge isnt working anymore..

hey have the same problema. here. teh only way to get fast chager is with the original charger al cable. PD charger give me fast charge. but all my other chargers that gives me fast charger in other devices gives me NOTHING now.
original charger 4300 ma,
PD: 1200 ma
fast chargers QC 3 and others: 230 ma !!
****ty old chargers : 230 ma.
so what the hell? I was thinking that I screwed the port of the phone with magnetics cables before read this.

Just my 2 cents here. Don't try to charge this phone with super fast chargers. Mine developed the well known fault that you needed to press the corner of the phone to get it to start charging. I even opened it and put a bit of a tape behind the ribbon cable connector (as some guy suggested on YT). It started charging again and then after a couple of weeks and a few more quick charges it stopped charging at all. I guess heat affects the connector or some element on the board. I've just ordered a new usb board and ribbon cable from Ali and if the phone comes back to life again I will never ever use the original rapid charger that came with the phone.

Question Charger for S22 Ultra

Hi All,
I am not an expert and hence seeking suggestions.
I have Xiaomi 120W Power Adapter (with wireless which can also be used as wired) and wondering if I can use for the S22 Ultra (Snapdragon version).
Thanks

If the power supports USB PD PPS it will charge at up to 45 W. If it only supports USB PD it will charge up to 15 W. And if it doesn't support USB PD at all, it will charge between 5 and 10 W.
It should be noted on the power adapter itself whether it supports PPS

My Huawei 65W USB-C PD charger used with the Honor Magicbook 14 charges at a report "Superfast" rate but that means anything above 20W. Of course there isn't a measured difference between a 25W and a 45W charger according to GSM Arena so YMMV.

Thanks all. As per this article it does
Xiaomi 120W Power Adapter Supports QC5 and USB PD + PPS Over USB-A Port

Hopefully no damage to the phone.

Does "Super Fast Charging 2.0" mean it's charging at 45W?
What is it if it's just "Super Fast Charging"?
Only one of my many third party chargers seems to show 2.0

Superfast 2.0 means anything above 25W I believe.
Super Fast Charging I think is between 15 and 25W.
Both of these would be potential speeds, as the phones won't charge at max rate from 0-100%. The rate starts slow at 0%, rises slowly to max, then starts dropping between 60 and 80%, falling to 0 charge rate as the battery reaches 100%

Thanks. All these different standards get very confusing!
I would have expected my "Anker Powerport III 65W PPS charger" to show 2.0, but it doesn't. The "MINIX 66W Turbo 3-Port GaN Wall Charger" does.

I just learned this myself, - but check your cables. The S22U is rated for 20V input, so it checks with the cable to make sure the cable can supply the correct power. USB-C cables have chips in them to identify the cable and its capability. If you use the cable that came with the phone you might get different results. I did for sure.
The PowerPort II also doesn't output the right voltage for the S22 from what I can understand. So there is that.
