Poco F2 Pro Charging Study - How Fast does it charge? - Xiaomi Poco F2 Pro (Redmi K30 Pro) Questions & Ans

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.

Tronsmart 33W Dual USB Car Charger with Quick Charge 3.0

Has anyone tried the below charger with the Mate 9? I thought it should fast charge since it's 5V 3A, but I'm only getting around 2A according to ampere. Trying to figure out if it just doesn't work or if I got a fake one.
USB Type C Car Charger,Tronsmart 33W Dual USB Car Charger with Quick Charge 3.0 Technology.Attached USB C Cord for Nexus 6P, Nexus 5X, LG G5, Pixel C (Benson Leung Approved) https://www.amazon.com/dp/B0146FK3G0/ref=cm_sw_r_cp_apa_9rWSyb3FQ80Y1
It's not going to fast change since it's 5v and not 9v like the OEM charging block.
Thanks. I mistakenly thought if it could fast charge a Pixel or 6p, it would fast charge the Mate 9. It does seem to be charging faster than a standard charger so that's good at least.
No, the Mate 9 uses Huawei proprietary super charging technology and he accessories today don't have it. We have to wait for more devices from Huawei to come out or companies are given the ability to use their tech.
Yeah, I knew it wouldn't be able to get super charging speed, but I thought it would be able to reach fast charging or whatever the middle speed is called.

The OEM Supercharge charger is also only 5v. It runs at a higher amperage, not a higher voltage.

Missing PD (Power Delivery) support

Hello guys.
I cant get PD charging to properly work on my Find X2 Pro.
I have a 45W PD Powerbank, but it only charges very slowly (1% every 5 minutes). Only with the USB port I get decent speeds (w/o PD) (about 10W).
10W is still very slow I think, considering the not-so-great battery life in my experience. I am going to travel in the near future, and I need a good battery.
Does this phone support PD? What is the maximum speed it can charge with power adapters/powerbanks without VOOC?
Oppo uses its own proprietary charging system (super vooc) and not PD, I have also had very slow charging if I dont use the original brick and cable. maybe try using the charging cable they gave.

Yes I know, but OnePlus phones for example also have VOOC but also support PD.
I tried every cable I have, the original cable is USB-A to USB-C so that one is not for PD. I get max 10W out of that cable from my PD powerbank.
i use Xiaomi 10000mah powerbank with QC2.0 onboard. And my Oppo chardging fast about 10-15% for 10.minutes.

PD Chargers Compatible with the Poco F2 Pro?

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 tried using the same cable (USB-A to Type-C) I have used with the Mi 9T with the original Poco F2 charger, which also uses the USB-A to Type-C with no success. The phone only charges at 18W. No Mi Turbo Charging at 30W.
I then went out to buy a 60W PD 3.0 charger and a USB-C to USB-C magnetic cable, but no success again. Standard fast charging, no Mi Turbo 30W rapid charging.
I have also ordered multiple PD chargers and tried many different magnetic USB-C cables but I can't get any of them to charge the phone at 30W. The only way to charge the phone at full power is with the charger and cable that comes in the box.
What I'm I doing wrong? Is it the magnetic aspect of the USB cables that prevents the Rapid 30W charging?
All the chargers I have bought are legit of Amazon with good reviews, not some cheap Chinese knockoffs as well as the USB-C cables. They were all advertised as PD 3.0 3A/5A max current.
Any help?
Ive tried all kinds of chargers pd/qc, the only combination i can charge the poco "rapidly" is with the original in the box charger and cable.
I can load it fast with 18 watts with almost every qc/pd charger i own, but only the 27 watt Note 8T charger and the original 33 watt charger will charge it faster than 18 watts.
Xiaomi Turbo charge is 33W, as in 11 volts by 3 amps. I guess you will not get any of those values from 3rd party chargers.
The best you can do it 9 volts by 3 amps as 27W charge with a QC 4 or 4+ ( I do not remember exactly) capable charger.
For both cases above your cable must be rated 3A or more and charger to have listed the values at output.
From what you are telling ( capable of doing 18W) your cable might be 2A max rated, as in 9x2.
But are you sure the charging is 9x2 or it is actually 9x3?
only xiaomi pd charge can 33w。others can only 27w max.
Ugreen magnetic charger cable was able to charge mine (crdroid 6.11) with 33w on original power supply. Non original power supplys charging speed was only 7.5w (5v 1.5amp) independent of charging cable. Tested using a passtrough meter.

This charger USB-C port 1 can charge at 11v/3A (from specs) I just ordered it, I'll let you guys know if this hold of true.
I use magnetic cable too with my Poco F2 Pro (before MI 9 Pro 5G "same cable") and works very well, as long as use Xiaomi original chargers (with other charger not work on Poco F2 and neither on MI 9 Pro).
Nintendo Switch charger and the Galaxy S9+ stock charger only charge at 5W. Kinda expected though.

Qualcomm Quick charge works, sort of?

Using the charger tool that can be accessed with the *#800# dial codeI I have noticed that some old chargers that support Quick Charge 2.0 or 3.0 can quick charge my OnePlus 8T. I didn't expect this after reading that earlier OnePlus models didn't support Quick charge at all.
It quick charges with 18W 9V/2A or slightly less when the battery is not too charged already. I use a standard USB-A to USB-C cable for this. The phone only says "charging" but it is definitely a lot quicker than standard USB 5V charging. Charging always starts at 5V and switches to 9V after a while (less than 30 seconds).
I also get 18W 9V/2A charging with a USB PD charger and a USB-C to USB-C cable. In this case the phone says it is charging fast. I have not managed to get it to charge with more than 18W using USB PD.
With a (powerful) charger that doesn't support Quick Charge or USB PD the phone charges at 5V with only 0.5-0.8A current which is surprisingly low.
Does anyone know what charging standards that OnePlus 8T officially supports?
I was not able to reproduce your behaviour. Cannot get to charge faster than 10W with USB A cables or 6-7W with USB C cables. All of this was performed with various charger that support both QC and PD.

Question How to make wireless charging faster?

So, when it is about charging, this Galaxy S21+ (Exynos) can be really choosy. With a lot of chargers, it difficulty reach 1.3A. Only few of the selected chargers (my Lenovo 65Watt laptop charger, IKEA 27Watt charger) it could reach 2A charging with wired. For wireless charging, it's even worse. Currently I owned 3 wireless chargers.
1. Energizer 15Watt charger. Never even shows Fast Wireless Charging.
2. Samsung EB-U1200 Wireless Charging Power Bank. This one shows Fast Wireless charging. It could charge up to 2A for a while and then once the battery temp hits about 39C (and it hits there within 5 mins), it throttles.
3. Huawei SuperCharge 27Watt Wireless Charger (with Huawei 22.5Watt SuperCharge Charger and 5A cable), performs same as Samsung Power Bank. Reaches up to 2A, then battery heats up and throttles.
I've tried different ways, including removing the phone case while charging but result is still the same. Does any of you have similar experience? or is it just my phone? Please advise me how to make wireless charging more efficient.
I've not tried wireless charging however for wired you need a charger that supports USB C PD PPS (this is a fairly new standard) and without this you won't get anything more than about 2A.
This Ravpower charger for £16 (£13 with current voucher code) works a treat hitting 4.6A when the battery is empty reducing as the battery becomes full. You have to use USB C to USB C to achieve this.

My guess is there will be a similar standard for wireless charging that you need to adhere to.
