quick charger

Is there some sort of special quick charger needed? None of my qc2 or qc3 chargers charge this thing at any sort of reasonable speed

Only the Huawei Quick chargers work. I have a Blitzwolf charger that isn't specifically quick charging, but it charges it fast enough. Also my Chromebook Pixel charger charges the P9 very fast too. USB C is amazing - I love having one charger for both the phone and laptop!!

The Huawei 9V2A charger is much faster. See the discussions and timings etc here ... http://forum.xda-developers.com/p9/help/charger-huawei-p9-t3373037

I purchased this:
https://www.amazon.com/gp/product/B00QEX83LA/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
It charged from 52% to 81% in 30 minutes (61.1%/hr), and another instance it charged from 27% to 90% in 70 minutes. (52.4%/hr). This is without touching the phone (screen off). Also I am not using the cable that the phone came with, not sure if this matters.

If I want order from ebay or aliexpress. Which should i get thats legit? EU plug.

Does P9 use Quick Charge 3.0 or 2.0 ?
Confused right now

Neither, it uses Huawei's own Fast Charging protocol. Don't get a Qualcomm QC2.0 or 3.0 charger, they wont fast charge the p9

I just order quick charge from china (aliexpress.com). It took 15 days to reach me in saigon-viet nam.
After testing, an interesting is that, when you use adapter quick charge (9v-2a), there are two thunder symbol appear on battery i/o one when you use original charge.
I am not sure the timing charge will com shoter. I will do some test and let you now.
But one thig you need to know, your p9 gonna be lag when use the quick charge. I am not sure this fault come from my quick charge adapter or because by itself function

It does not lag here, but you need to have in mind that real quick charge kicks in when screen is off. I see wattage difference in my wall tester the charger uses when I use the phone and while it is idling.

Dash Car Charger

I was wondering if I had a quick charge car charger with the same wattage and voltage as the dash equivalent would I still be able to quick charge my op3 if I use the cable?

Not sure, but over last weekend I used mine for navigation and Bluetooth streaming and it charged fine with a regular QC 2.0 car charger. I know it doesn't use QC 2.0, but it charged fine. Screen was on for an hour and half and it started at 88℅ and got to 100.

Hello,
Have you asking to OnePlus when he will be available again ?
I'm interesting to buy this one to remplace official Dash Car Charger: http://www.mobilefun.fr/60000-chargeur-voiture-oneplus-3-olixar-high-power.htm
Good or bad idea ?

The are available from oneplus.net right now... I got 2 of them last week (took less than 3 days to get to the US from China)... I just checked the website and they still show them as in stock.

I've the official one and it's awesome :starting at 50% GPS and screen always on for an hour and finish at 100...

It will charge but at normal USB speeds and not QC. I purchased the Dash Car Charger which works great.

Compatability
Does dash charge work with a charger from older phones?

Lenovo K8 Note Battery Charging Issue (Showing charging over USB Error)

Hi all.
i bought a lenovo K8 note and also it was working perfectly and now i have a problem in charging.
its already providing a turbo charger with this device. since before two day i connect OTG on my phone and after that when i connect charger all are showing charging over USB and its deadly slow to charge my device. it takes almost 9 to 12 hour for 0% to 100%,
i tried changed cable with new 2.4A fast cable. try with USB 3.0 Ports, Try With Wall mount Chargers 2.0 AMPS, 3.5Amps etc.
I reset the device and also i am flashed my rom with 7.1.1 (Stock ROM). nothing was helpful. still now my device showing Charging over USB while charge with any charger on battery screen. deadly slow to charge up device (almost 12 hour need to full the battery before it was 3 hour maximum time)
So anybody have the same issue. I hope our teams got a solution for this

Been having this same issue myself, I'm too lazy to visit the service centre though, try visiting it maybe?

I am unlocked my bootloader so is that will cause loss warranty ?

I am having the same issue

I was try to change the all are like charger, cable, etc. But nothing was helpful. Basically i am a electronics tech. So I just bypass the charging Lines directly to battery with a suport of and diode.
After that it was much better (but can't see the percentage while charging)
Now I sell the product to some shop..
Now happy with asus zenphone max pro m1

In my finding i got a Final report.
It's battery response issue..
The battery have turbo identifier inside. T+ t- mark ups. (I removed back cover and checked all)
You can see the turbo controller in battery.
Maybe if you are in warranty quickly visit services center and ask for battery replacement.
Have a good time ahead.
Admins This thread is now resolved my self. So please close this with my solution.
Thanks.
With love

Mi 9 SE charging question

Hello
I've got question about my Mi 9 SE. Recently I bought a USB tester for voltage and current. When charging the smartphone it shows most of the time time 7V/1.8A. Shouldn't it be around 9V/ 2A or 5V / 3A? (Tested on original cable and charger)
Edit: One more thing - since miui 11 update - my phone does this weird thing that when I connect the phone to the charger, in the first 10 seconds quick charge turns on, then it turns off and on again (further on it is stable)

me too, its charging at 15w most of the time, may be 18w if power off, havent tried
switching from fast to slow then fast is normal, it means it detect and enabled qualcomm charging protocol, afaik

Question Poco f3 fast charge works then stops

Hi guys
I recently bought a poco f3 256g 8g ram, it's a great phone but one thing I have noticed is that when you try to fast charge it, it works then stops with the charging icon saying its charging even when you pull the charging cable out. I checked it with accu battery and it show that its not charging with minus amp age going in. You then turn the phone off and the charging icon resets. It charges fine when you don't use a fast charger and use a non fast charge brick. I don't have the original f3 charger but have tried my mate 20 Pro fast charge brick as well as my old s8 plus charger and new cables it only charges on a non fast charger. Any ideas anyone?

make sure the fast charger is 33W

Hi thanks for the reply are these phones really that sensitive to the the wattage, the charger I had is a 40w Huawei fast charger and the other a Samsung 18w both start to charge then stop and you cannot charge it with any charger until you turn the phone off. I have tried to get a official poco 33w charger but they are not easy to find.

i have used my 33W charger and another charger 18W fast charger and everything looks fine. if your phone is still under warranty, go to your nearest mi service center.

Hi I got it secondhand so I can't I'm afraid I'm sort of wondering if its a protocol thing as it charges fine with a non fast charger I might flash it in time and see if its a software issue, I can live without the fast charge but it would be nice to have the capability.

They are ... You need to look at what's written on the charger , not the big W numbers.
Original charger supplies 33W by using 11V and 3Amps.
Written like this on the charger : 11V=3A 33W
Nothing else will work , I for example use 6A cable and it does not charge well - the amps are enough as you can see but the cable most likely can't handle 11V...
Open google , search for authorised xiaomi repair center and buy charging brick/cable from them. Sometimes they too just pick random charger so you'll have to check when you receive it that both the cable is rated at 3A and the brick supplies 33W like written above

Yw. My reply above mainly covers how to get 33W charging , but I have no idea why it's refusing to charge?
Oddly enough I have the same exact issue happen like bi monthly... Pretty rare but usually happens when phone is REALLY hot ( mine is modified to allow higher temp ) + the charging port is fked and I'm using non compatible cable lol.
Is possible that every once in a while it all lines up so that the phone doesn't recognize charging brick due to bad port situation + it being rly hot sends it into some sort of charging lockdown?
Either way mine is very rare.
I suggest you first get the cable/brick those are like 20/30$ + I bet any repair store would ship it to you. Then if it still doesn't work you can start troubleshooting software/port/motherboard see where the issue is...

Hi thanks for the reply I have found a poco charger on ebay and a lead not too sure about the lead but I think its suitable. I'm not sure what's going on with it but I will let you guys know if it works. I did read somewhere that someone had a similar issue and that they disconnected the battery and after that didn't have a problem, I think I will try the charger first.

Hi guys got the charger connected it up works then goes into minus amps and stops charging until you turn it off again. So I'm wondering if its worth flashing it? Really frustrating

Nox Vidmate VLC​

Hi guys just a quick update I connected it up the other day and watched the ampage and voltage go into minus again frustrated I just left it and came back 10 minute later and it charged. It turns out with the original charger it goes into minus amps and voltage but if you leave it it charges and ampage goes up with the voltage.if you disconnect the charger while its in minus amps and voltage it says its still on charge and you have to reset or turn the phone off before you can attempt to charge it again. But if just connected with the original charger without disconnecting it while in minus volt and amps it will charge and the volts and ampage starts charging. I have come to the conclusion its a glitch or bug in the charging protocol for the fast charging or software..
