What kernel and Rom u using??
Sent from my HTC One X using Tapatalk 2

sounds like your phone thinks its charging from a usb and not ac when its charging from the mains open settings > power
under battery status it will say either not charging, charging (usb) or charging (AC).
if its saying usb then there is something wrong with the cable thats stopping it from showing s an AC adapter.

Have you tried a different adapter?
The cables could be fine, but your adapter/plug is defected.
Also, do as treebill said. Try checking in which mode (USB/AC/Not charging) your phone is recognizing as being charged.

I have exactly the same problem, I'm using official usb cable and adapter. I had tried other cables and adapters but same thing. My One X is not unlocked or rooted, and I'm with the last official rom 2.17.401.2 but it was happened and with previous rom 1.27.401.11. Even with switch off phone charging is very slow I try to restore my phone but nothing at all. Sometimes it's charge like it should but most of the time it's slow. Any suggestions or I have to go straight to repair center?

Ok.
Li ion batteries take 3-4 hours to charge. If its taking longer, there is huge current draw from the phone. Or, as you say, "no".

help me...

Are you REALLY sure your chargers aren't messed up?
I f**ed up the charger given with my One X(details below) and after that, my charger would only give me usb power instead of ac. I've been using this charger bundled with my Samsung P2 mp3 player that I got 4 years back.
We had gone on a trip where the room's fan rotation knob was missing, so the only thing I saw fit to change fan speed was fitting that tiny pin from the fan regulator in my AC Adapters usb port, which messed it up. Retarded I know, story of my life... -_-

Hey there, I faced the same problem. Having a blackberry Bold3, I tried recharging my OneX with the charger that came with it. BB charger charges my OneX WAY FASTER than the HTC charger that came with the phone. (1hour max for full charge) And battery holds an entire day too.

no one??

If you haven't rooted nor unlocked, and your phone was charging perfectly before, then I don't think it's a software issue.
It's either your charger or cable. If you have tried a different charger/cable that works well with other phones, then I guess you need to have your phone looked at.
Good luck

This is a relief. Mine took 3 hours to charge from 0 to 100 , I thought that there's something with it.

Does it show Charging (AC) or Charging (USB) under settings > Battery ?

Use the original charger and cable all others are slower

So slow charging ...

Hey guys, i bought a xiaomi mi max 32gb.. i have the original european charge and the official cable .. but the phone charging very slow.. from 20 % to 40 % almost 30 minutes. The phone and the components its new . never opened , tell me what to do please !

Considering this phone has a large battery, it's normal it takes more time to fully change it. Maybe next time get a phone with smaller battery capacity, and then you can charge your phone few times a day. [emoji14]

I'd say that's about the charge rate I'm getting. I've got the Global version with the same European 2Amp charger. I'd have to agree with iJohnny, the 4850mAh battery is a bit of a beast, so it will take longer to charge. 20% battery gives me around 2hrs SOT depending, so it's not all bad!

The MI MAX is compatible with Qualcomm Quick Charge 3.0. The included charger, however, is a simple USB charger. Buy a Quick Charge 3.0 charger to charge the phone faster.

I saw a thread on mi.com forum and a guy have the 3.0 charger but he facing slow charging too. So before I buy the charger I want to be sure that the phone will charge fast. I have a Xiaomi 10.000 may quick charge. I don't test it for now. I will test it and I will write about it.

If someone can please send me a link to buy the official Quick Charger 3.0 for mi max !!

Yeah. Good and affordable brand in my opinion. I already have android TV box from them and I am very happy. So I decided to get their QC 3.0 charger. Good quality charger, good and long cable in the box.
Google it, and you can even find some videos on YouTube about their charger.
But if you plan on using Xiaomi Eu ROM then you won't have QC 3.0 because it's not enabled in that ROM.

Well it's faster than charger you got with the phone, but not as fast with stock.
No idea why.
I am using MIUI 8 with Android 7 now (beta) and its super fast charging.

Point is pick a charger from Qualcomm list and get it.

Well I know that. Is there specific tempered glass that can apply perfect on my phone? But not to cover the speakers and cameras. I don't want a universal tempered glass, but only a glass specific for my phone

Now I thinking that while I have a Xiaomi power bank quick charge 3.0 10.000 PLM01ZM. Why the phone can't charge fast ? Some guys told that the battery is too high so if I buy a quick charger 3.0 I will not see any difference right?

Mi Max is not quick charge 3.0.. I know that snap 650/652 is but xiaomi limit this in the kernel, dont know why, only get quick charge 2, with the normal charger takes 4 hours to charge, with my quick charge 3.0 takes 2.5 hours

As Qualcomm has listed it in the PDF, the Xiaomi has paid to have it enabled.
So devices are QC3 enabled as it says in pdf. You just need certified QC3 charger.

Fast Charging Support

Hi all,
There's no mention of Fast/Quick charging anywhere about with this phone and every review I've seen specifically mention it's not supported.
I've just plugged my phone into a Qualcomm Quick Charge 3.0 power bank and the below icon has appeared. Is this a quick charge icon?
It definitely seems to be charging quicker than with other chargers I've used.

Yes, that is Qualcomm quick charge icon. It supports QC 3.0.

Mine says charging fast when plugged in so its supported.
And it goes really fast. I can watch youtube and the percentage will tick tock upwards every few seconds even when being used.

It comes with QC 3.0 charger... Hello...

The charger I received with my device definitely doesn't trigger the QC icon. I'm UK based and it's an EU charger through an adaptor so that might be screwing it up.

Charging speed is enough with stock charger.
dont use charger with above 2.4 amp output

No longer "Super Fast Charging"

My phone used to show "super fast charging" on the always on display when connected to the 45w charger. Now it just shows "fast charging". Time estimate is now equal between the 25w and 45w chargers too.
Tested with two cables - the one included with the 45w charger and also a USB 3.1 E-Marker cable that worked with super fast charging before.

This can happen when either the phone or the charger itself is too hot.

Itll help you determine if it is the same of not.

Ampere is useless on my note 10+. I needed to use an inline usb c power meter.
The issue is that the power meter always showed just under 25w of power from both chargers, even when the phone showed "super fast charging" on the 45w one. It explains why there wasn't a huge difference in the first place.

I found a solution here and I tested it myself.
when i connect it with simple fast charger the circle is white but it is blue when connecting it with the original fast charger that came with the phone.
So this means, that "super fast charging" notice is removed by Samsung with the latest updates

This is not true on mine. The blue circle simply means it is connected to an OEM charger. Mine still charges in QC 2.0 mode at a maximum of 17W. It should be charging in PD 3.0 mode. You need a USB tester that can identify charging mode. Can you verify the charging voltage and wattage?

I dont have smth like that. Anyway both chargers I use are OEM. One for note10+ and the other for Note8.
Havent checked precisely the charging time but i took for granted the solution read on other forums

Also the same after last update

So this explains why my At&t Note 10 + does not super fast charge with the original samsung 45w dual car charger. The charger has 2 ports one is 15w that will fast charge the other is a usb-c port that is 45w.
When I use this port the phone connects it will say charging super fast 2.0 it will only charge 2 mins then it will stop.
Hopefully in the next update they put the super fast charging setting in the phone like the note 20 ultra has

Mu US Unlocked SM-975U1 with all updates, including Nov security updates and OneUI 2.5 still says Super Fast Charging when charged via the Samsung charger that came with it.
