My Poco F2 Pro charges fine (and very fast) with a USB-C to USB-C cable connected to a USB-C fast charger such as a Samsung. But if I try to charge it with a USB-A to USB-C cable connected to any charger, the phone only draws 0.5A ( I have a USB power dongle to check this ) and that's not fast enough to actually keep the phone charged when in use.
Every other phone I've tried will at least draw over an amp, even those which support fast charging.
I've tried multiple chargers, multiple cables, and nothing except C-C with fast charging will actually charge the phone.
Is this normal behaviour for the phone, or do I have a fault with mine. (It was bought second-hand with a warranty, but no charger or cable in the box).
No it's not normal, mine charges at least at QC3 speeds with various compatible chargers, powerbank and cables. Even with Huawei's fast charger, which seems not to be fully compatible, it charges about 2A (measured in accubattery).
It has a strange behavior if it's like that. What about original cable and charger, that's A to C, should charge very fast.
I had another issue regarding charging, whichever charger/cable I was using (let's say max 5V/2A), in accubattery it was measured around 3A, and the charger would overheat like crazy. You know when you want to charge slower, all what they tell you on the web is to use a less powerful charger... and this is what I did, but not with great results though. On my previous phone it was working just fine. On my wife's Mate20Pro it's also working well, but not on F2Pro. Even if the cable was rated 3A and I would connect it to the original charger, it would still draw 5A from it... Only way to solve it was AccA apk so I limit the current that the phone draws and I'm happy.

Unfortunately I don't have the original charger and cable as it was a used phone which is otherwise in perfect working order. I've had no problems with c-c fast chargers, but nothring else works.

What ROM is on the phone right now? May I suggest going completely stock with MiFlash to rule out the software part?

Just search and buy original charger if u want full charging speed, one guy made a great test of different chargers and different cables on this phone, check this here https://forum.xda-developers.com/t/poco-f2-pro-charging-study-how-fast-does-it-charge.4189013/
There's something wrong with his device.
0.5 A is too low for any charger.

It seems the only way to fast charge a N1 is with the supplied wall charger. Standard Micro USB chargers whould only allow at much as 450mA of charge current regardless of the adapter current capacity.
The bundled charger however, manages to push 900mA into the N1. I made a cut in the charger wires and measured the current draw to make sure.
Now.. I'd like my car charger to be able to do the same. There must be some hack in the plug of the N1 charger since there are only 2 conductors from the case to the plug. You can see that the plug is somewhat longer than similar Micro USB plugs..
So I tried to see if one of the 3 unused pins can tell me anything but.. they seem unconnected as far as I could tell. Diode measurement (to test for any digital part inside) also did not produce any results. The next obvious step is to take the molded plug apart but I'd rather not...
Does anyone have any clue as to what makes that plug so special?
And please - I did my tests with a bench power supply - not the car chargers - so don't go around telling me it has to do with charger current capacity.
Thanks,
Nir
are you sure the micro usb cords you are using are able to handle the amps? most chargers made prior to now, only push about 450mA, the G1, and N1 chargers i have push a full amp though. I just ordered a car charger that pushes an amp too. There is nothing "special" about the plug.

I beg to differ. All the cords can easily supply 1 AMP. It is the phone itself that decides how much to draw from the charger based on something IN THE PLUG.
I am an electronics engineer so do understand I know perfectly what I am talking about
And your 1A car charger does not supply anything over 0.45A to the phone.. you will see that if you are using the phone while it charges (say nav or phone call) the phone actually looses some charge albeit it being charged... This will not happen with the stock wall charger.
I have a 900mAh car charger that I use and it does in fact give 900mAh to the phone while charging. I can tell because I used a 450mAh charger at home before and it was slooow and I could drain my phone while charging it. With the car charger I can stream music with spotify, use the GPS, have the screen on full brightness and the battery % will still go up.
I also bought a new wall charger recently, which is 850mAh on the USB port and has a 350mAh charger for a loose battery as well, works quite nice.
Has anyone measured the voltage or put a scope on the output of the stock charger?
maybe stock charger has a slight variance in voltage over USB chargers or some signalling going on and this tells the N1 to take more current from it?
I would like a solution to this too I've seen my phone discharge while on a supposedly 1A car charger using co-pilot.

Forget the numbers on the chargers - what counts is what really goes into the phone and that needs to be measured with a current meter (test equipment). What you may think to be fast might not be that.
Original HTC chargers obviously do the trick of fast charging but this comes at a price compared to the $3-$4 garden variety on Ebay and the likes.
now I cannot help you with the electronics at all, but, my old HTC Touch Pro charger seems to charge the same as the one which came with the phone, is this correct?
(suits me if it is, as then I have a charger for home and work)
my blackberry bold 2 charger only says it outputs 700MAh, but both the google and htc chargers both say 1.0A

Yes, it is just anecdotal evidence as I don't have any equipment to measure it. But my phone no longer discharges when I use it while charging, which it used to do with the old charger I used. So while I can say for a fact that the charger I use now is faster, I can't say by how much (this goes for both the car charger and the one I put in the wall socket).
I ordered this charger a few weeks ago and it charges my phone as fast as the original charger. The label says 5v / 1200mA.

HTC Touch Pro = mini USB
Nexus One = micro USB
Not an engineering here, but I am guessing the phone not always drawing more than 500ma may be is to do with the charger itself.
There is this "fast charge" USB standard where a wall plug has the USB data pins shorted to indicate that it is a wall plug and hence the phone knows when to draw more power. So even if the charger is rated 1A, the phone might not know if it could utilize that if those pins aren't shorted. Try doing a quick Google on this ....
If someone can test if the stock charger that came with the phone in fact does have those pins shorted that would confirm part of this theory.
For all practical purpose - I used two cables/plugs with a bench adjustable power supply. Simple micro USB plug would only let me draw 450mA regardless of power supply voltage in the range 4.5-5.5V. Tried shorting data pins - nothing. Tried shorting spare pin to VCC or GND or any of the other pins - nothing.
Used original cable and plug - draws 900mA at voltages from 4.9-5.5.
So it's in the plug somehow.
Tried (very difficult) to see if the pins on the plug are shorted and all 3 spares (except for 5V and GND) seems unconnected.
Next step is the irreversible hot knife...
I'm bugged by this, too. I tested with my desktop dock connected to my car charger (which states 1000 mA): it loads slowly and my battery widget reports USB- instead of AC-charger.
Might it be that the phone tries to load more than 1000 mA at the beginning to be sure that it doesn't overload the charger? And if that fails, it falls back to 500 mA?
Could N1 use a simple logic of:
- always watch the voltage
- start drawing 500ma (or whichever is the lowest current as per USB spec)
- increment in say 50ma steps
- if voltage drops below 4.x V, back off and stay at that level
I just did a little test of my own. I have a Palm Pre car charger (actual Palm brand one labeled as 1000ma output) and I plunged my N1 into it on my way home from work. In twenty eight minutes, my battery went from 47% to 70%. Much faster than plugging into my computer, which is 500ma max. I don't have any fancy test equipment, and don't claim to know a whole lot about electronics, but seems pretty fast to me.
I have a 4-port 2A 5v USB charger, and connecting it to my Nexus OR Milestone with a MicroUSB cable (the one that shipped with either phone, or the one from my Kindle) yields painfully slow charging - it basically won't charge if you are using the phone.
Connecting the Nexus One charger yields fast charging on either phone - so it is not HTC (or Motorola) proprietary.
The Milestone comes with a 900mA USB plug, and connecting THAT to either phone with either of the MicroUSB cables yields fast charging.
I have another aftermarket 2 port 2A 5V USB wall charger (brand: T'nB) AND I have an iPhone USB plug, and both give fast charging on the Milestone, and I have not yet tried them on the Nexus One.
Breakdown (on things I've tried):
FAST CHARGING on Nexus One AND Milestone:
Nexus charger (either in the US (110v/60hz) or in France (220v/50hz) through an adaptor)
Milestone wall French USB plug (which I think is something odd like 850mA at 5.9v) with ANY microUSB cable (in fact, it seems to charge both of the phones faster than the stock Nexus One plug)
SLOW CHARGING on Nexus One AND Milestone:
USB plug on computer
One aftermarket 4 port 2A 5V USB charger (NOT a hub, only a charger)
FAST CHARGING on Milestone, untested with Nexus One
T'nB 2 port 5v 2A USB wall charger
Apple iPhone 1 port 1A 5v USB wall adaptor
Seems found the answer for Fast Charging N1
I had just do some test for Charging N1 With Original AC Charger , Other band USB Charger and PC USB charger.
1. Orginal Charger give N1 from 0% to 100% at about 2 hour and something.
2. The other band AC charger and PC USB Charger can only finish the same job over 5 to 6 hours.
The Fast Charging is Due to 5.1V (Measured at N1) and 5.2V(Measured inside AC charger). 0.1V Drop is due to resistance of USB cable.
The Slow charged is due to 4.8V (measured at N1) and 5.0V (measured on PC USB and Other AC Charger)
i.e. Original Charger mod from 5.0 V to 5.2V (about 10% increase in Voltage)
Looks my theory is correct then ? N1 watches the voltage and if it droops too much, it backs off the current.
So the key would be: get a charger than can maintain at least 1A @ 5.2V, use
a decent gauge, short wire from the brick to N1.
Has anyone tried a Blackberry charger on the N1? Will they work to full capacity as well? (They're on Amazon for a fiver)
Because the nokia charger is working
http://pinoutsguide.com/CellularPhones-Nokia/micro_usb_connector_pinout.shtml
see info under table.
I tested also HP charger + standard USB cable delivered with Nexus, and it is charching cca 1A.
Then I tested one noname Carcharger + standard USB cable delivered with Nexus, and also charging cca 1A.
I dismantle the noname carcharger and here is a result:
data line (pin2+3) is shorted and connected do + (pin1 ,Vcc) thrue resistor cca 630kOhm.
1 - 4 = 5.1V
2,3 - 4 = 3.2V

I try to use power supply 5.2V 2A with cable without dataline (pin 2and3 not connected) and it is charging 480mA only.
I have now tested with an HTC car charger for the HD2. It's fast charging (tested with Waze running, two bluetooth connections and playing mp3 - and it's still loading the battery, whereas before it would be stuck at the current percentage) and even shows AC power instead of USB.
I didn't get a charger with my OnePlus One. No major deal as I have a few USB chargers around but each that I've tried so far has had problems charging the phone.
Has anyone else experienced this problem?
Thanks,
James
Yes. The phone basically needs the included charger to charge. I think this phones charger is 2amp instead of the normal 1amp. My external battery packs won't even charge the device at all. It stops charging after the lights on the battery pack turn off. Works perfectly on every other device I've ever used it on.

Yeah the stock charger is 2A, depending what phone you have prior to this most chargers are usually 1.2-1.3A.
I believe some of the Galaxies, N7 give you 2A as well.
I personally use my 3rd party charger to charge the OPO. Works fine and is 1.8A, I love the 2A and all but that OPO USB is way too short, maybe I'll interswap them with another USB.
OP if u need a cheap charger and works well, http://forum.xda-developers.com/goo.../hands-best-fastest-cheapest-nexus-5-t2729066 try looking into that. ~$5 and they'll ship you two of them. Or get in contact with OPO and tell them you didn't get a charger. The charger should have been added to cart for $0.00 with your order.
i think you need at least 1.5 amps to charge the phone but i dont have it yet so don't take my word
You don't need the original charge to charge it. I have charged mine on various chargers and it works fine. If the charger is less that 2A though it charges slowly. I use a charging brick from my HP Touchpad (2A) and whatever usb cable I have around and it works just fine.
The only charger that's charging my Pixel C is the original charger that came with the device.
I have a number of other chargers here, even a QC3.0 charger, and another USB-C charger (from a Moto Z2). None of them is charging the Pixel C! They do light up the charging icon, but when I look into the battery settings, it says: 'not charging'
What are your experiences with charging the Pixel C?
i use the factory charger, the charger from my oneplus 5, and if it is connected to my pc it charges during that time. i remember using a few others also and have had no issues with any specific charge method. in fact, i am sorta surprised by the post. i know the factory charger has a built-in cable, so i might first look at the cable used with any other charger. i bought some usb-a to usb-c cables from amazon and the oneplus 5 is a good usb-a to usb-c cable.
I purchased this from amazon
Anker Quick Charge 3.0 and USB Type-C 24W USB Wall Charger, PowerPort+ 1 for Galaxy C9 Pro, Nexus, Moto and More
I think it came with a cord

this is optional.

All my chargers do that, including the original one. It takes maybe half a minute to a minute before this changes to "charging" in battery settings. So it's not a charger problem really.

well.... it once drained the battery, the screen stayed on because a charger was connected, but it did not actually charge the battery. i thought it was charging, some time later i noticed that it was not!
this and other experiments made me write this question on the forum.
update: due to a problem with the PIN I had to factory reset my Pixel C https://forum.xda-developers.com/showpost.php?p=73807273&postcount=20
and ever since, different chargers NOW do charge the Pixel C!!! strange, but that's how it is now....
Sorry for resurrecting this old thread. Hopefully this may help others with this problem.
I am on my second pixel c and both had/have this problem with aftermarket chargers. For me, the problem is not that the chargers won't charge the unit, but that they won't charge the unit every time they're plugged in. My workaround is to run the ampere app and repeatedly plug the charger into the unit until it shows it charging. Normally it takes no more than 5 tries. It even charges rapidly.
I currently use an anker charger that works as above, my previous charger, Aukey, also worked similarly. Strangely enough, it doesn't matter which end of the cable(usb-c or USB) is removed and reinserted to get the pixel c charging. This proves to me that it's not a bad connection.
I can confirm that the Anker aftermarket charger works great. When I plug in the Pixelbook charger into the Pixel C the tablet will charge but it will reboot android everytime.... Very annoying!

Apple ipad 18w charger. Charges it ok.
Anker 5 ports QC2.0 not charging.
Aliexpress QC 3.0 charges but makes some bad touch screen errors and ghost touchs. It is impossible to use Pixel c.
Huawei 5v 2A. Not charge
With charge i mean in the battery options icon i can see charging...
Thanks to all.
Has anyone found any cheap chargers that can charge this phone like the Essential charger does (really fast)? I have bought two different chargers and neither of them can really even charge the phone. The lock screen says it's charging slowly, and the battery meter acts like it's charging, but it doesn't actually charge. The chargers were both Quick Charge 3.0 chargers too. None of my old phone chargers with a type-c adapter will charge the phone either.

No idea. Honestly, I don't know of anyone who consciously needs to control the speed of their charge. I avoid charging overnight by rapid charging during the day at work.

I'm not sure how Android is programmed to display "Rapidly Charging", but I'm sure it's not by charging standard. Probably based on supplied power, but it definitely doesn't charge as fast as the stock charger. I noticed this with my QC chargers. It will say rapidly charging for a couple minutes and then just not charge at all or say charging slowly. Frustrating as hell so I bought an extra USB PD charger.
My Samsung chargers all work, and charge the phone to 100%. They just say charging, not quick charging, but whatever... The % goes up.

Phone needs a charger with USB-C Power Delivery and not QC. Anker has at least one model and Incipio has one as well. There are many others on Amazon.. The cool thing about those is that they also change my XPS-13. Only carry one charger when I travel.
I've got a few QC 2/3 chargers and a few USB-C PD chargers and what I've found is that depending on which USB-C to USB-A makes a difference whether I get rapid charge or not.
I'm slowly converting over to USB-C to USB-C but it is stupid expensive for some things like the power packs with USB-C...
Anyway, try a few different cables and see if it works for you, also it seems to work a tiny bit better on the Oreo Beta however my QC 2.0 car charger doesn't charge as fast as it did on 7.1.1 but luckily the car chargers are the cheapest USB-C PD items to buy, roughly about the same price as a cable.
One last note, the same charger and cable don't always go into rapid charging mode so replugging the cable in sometime kicks in rapid mode for me.

Alas, not available in the US...
When i plug my P7P in to an Anker Nano III the P7P vibrates 4 times about 10 seconds apart before charging commences normally, is this how a PPS charger negotiates with the phone or is there a problem be it the charger or the phone?
Didn't even know what PPS was, but just did some reading on it. That explains my car charger. The delay happens no matter what I plug up, my iPad, wireless earphones cases, Pixel 4 XL, and now my 7 Pro. Seems like they're working as intended.

Never noticed this with my OnePlus 9 charger (that's also a PPS charger). I'll have to look out for it next time.

When i plug my P7P in to an Anker Nano III the P7P vibrates 4 times about 10 seconds apart before charging commences normally, is this how a PPS charger negotiates with the phone or is there a problem be it the charger or the phone?

Well, even if the charger fails to negotiate the PPS charging protocol, it would be still charing at minimum speed, usually the standard 5 Volts at around 1-2 Amps (depending on the charger/phone).
It seems like it's being interrupted for some reason. Unless you have the same issue with other chargers, I'm pretty sure it's the charger you're trying to use (Maybe even the cable).

I've noticed that recently with newer chargers, some even explicitly mention it on their pages.
I don't know why newer ones are doing this compared to older PPS chargers, speculating either lower cost for a charge control chip that instead has to reset between negotiations or it's intentional to solve bugs with devices that might not negotiate right unless the connection is reset.
Cheers for the answers everyone, if it wasn't for the regular nature of the handshake (for want of a better description) and then charging as you'd expect I'd say the charger is wonky (Anker Nano III) simply because it is brand new.
I have ordered a new cable just to rule that out all my old cables as well.
I must have more charging bricks knocking about than a charging brick shop but from what i can gather only the Nano III is a PPS one
Hopefully it is OK now and the new cable seems to have sorted it out but i guess i will see more in the coming days.
The cable i got is an Anker 643 (just for future reference) I have always used Anker cables so i must have had an iffy one.
Hi, i noticed that my phone wasn't fast charging, despite i have an anker that reaches 18w. What kind of charger can i buy that allow my pixel to have fast charge?

Any charger which can handle at least 23w. Anything over that(per port) will be useless.
Also the biggest gripe of the Pixel 7 series is not having rapid charging.
Thank you for the reply! I had to buy a new charger because mine was not compatible I guess. The phone didn't show up the "fast charging" indication and it took 2.20 hrs to charge from 30% to 100%.
The Anker Nano 3 is 30W, PD 3.0 and PPS this is the UK version but all other regions version have folding pins which make it super compact.
