Coming from RN3 Pro i thought my battery is broken, but it's just Quick charge. superb speed.

10/8

Not as i expected
I bought UGreen charger 30W, works for QC 3. 0 et QC4. 0 and recording to Amper app my standard charger that cames with the phone from xiaomi is delivering from 1600 mAh to 1790mAh max
And the fast charger from UGreen and according to the same app it's only deliver 2200mAh to 2250mAh maxis this normal?!
Can we call this 2250mAh a fast charging
P. S: i get to flash mark next to battery livel in my phone

Full charge around 2.5 house with Anker Q3 charger

this device need some thermal module to charge fast, charging speed is lower than Redmi Note 5 Pro

Can this phone support or charge with a 5v 3.5 amp charger? Is it faster? ZeroLemon

Next week getting a new Note 4 - and zerolemon 10,000mah battery!
I need to deep cycle battery 6-8 times to get phone to display the current vbbatt % correctly. The manufacturer for zerolemon says turn off fast charge and charge 12hrs each time.
That being said, with fast charge off, can I use a 5v 3.5 amp charger I see on amazon and possibly charge the phone faster than 12 hrs like normal is using a 2.1 amp charger?
Anyone tried this with let's say even the stock battery does the battery actually charge faster due to the increased amps or would it be a waste and still charges at the slower 2.1 amps?
I never deep cycled the battery and the longest discharge I got was 1 week with 16 hours on screen time...you just need to make sure you use an updated kernel with the zL fix.
The amperage rating is the max the charger can put out. The Note will draw the same amperage on either charger because they are both 5V.

But will the phone charge faster on 3.5 amps at 5v vs the 1.5 amp or 2.1 amp the stock charger puts out? I am getting ZeroLemon and need to deep cycle the battery a few times and am trying to have it fully charged in less than the standard 12 hrs - was hoping a charger with more amps would cut down on the 12 hrs lol

i just used the stock fast charger on my zerolemmon with fast charge on and i never let it go the full 1 hours. Ive had insane battery life with it so i dont think it matters

Your Note 4 will draw a maximum of 1.9A on a 5V standard charger and a maximum of 1.66A on a 9V Quickcharger. If you multiply these values, you will get your "charging speed" in Watts: The maximum is 9.5W on normal charger and 15W on a quick charger.
Using a higher rated normal charger (eg 5V/3A) will NOT INCREASE charging speed. The Note 4 will never draw more than 1.9A on 5V.
Using a lower rated normal charger (eg 5V/1A) WILL DECREASE the charging speed. The Note 4 will notice that it cannot get 1.9A from the charger and drop the current. Bad and/or long cables can also influence the charging speed negatively.
Also noteworthy: Quick charging will only work when screen is off. As soon as you turn your screen on, the charging speed when connected to a quick charger will drop from 15W to an extremely slow 5W. The only fix for this horrible Samsung joke is a custom ROM like CyanogenMod.
You can charge your Zerolemon battery nicely with the original Quickcharger that came with the phone. That will do 15W and is as fast as you can possibly charge.

Charging speed isn't that great. But its okay considering that this phone sports a large 4100 mAh battery.
5/10. Battery capacity is large and there's no fast charging, so it sucks.
I dont know why but even though lot of people of complained that it takes a lot of time , Mine charges from 10% to 95% in under 2 hours which is great
Most people that complain have bad cable. For what I see, Xiaomi uses some bad cables in India. My phone was bought from China and it charges with 1800mAh, which is great since charger is 2000mA and system consumes a little.
Use Ampere app and measure the rate of charge. If it is under 1000mAh you have something wrong with charger/cable.
Fast charging should have been enabled
Average
Fast charge (2A) is present. Charge rate up to 1800mAh, what is good.
Better if quick charge (QC) was enabled.
My charge rate up to 1650 mAh.
mine upto 1960 mAh
Qualcomm Quick Charge 3.0 IS supported.
After connecting the phone to Samsung's "Adaptive Fast Charge" charger results in average 9V and 1.5A charging after negotiation which takes around 5 seconds.
it is ok, I get up to 1800 mAh

It supports QC 3.0 but to enable it, you'll have to flash a suitable custom kernel. In my opinion, stick with the default fast charging system because putting too much stress on your phone's CPU can cause overheating issues and no doubt shorten your phone's battery life.

I use a quick charger 3 (adaptive) it communicates to the device and changes the amp and voltage according to the device so it doesn't fry the mobile
T6
which rom support QC2.0

It took 4:30 hours to charge from 0% to 100% with original charger.
Charging Speed
it takes around two and a half hour to charge it zero to hundred percent.
Unfortunately, the 2Amp fast charger that appeared in some reviews cannot be found in most packages, so 2600 mAh/1000mA(charger power rating)= about 2,6h to charge
It takes about 3+ hours from 10% to full. I have an extension plus that has two USB A that I can use to charge it. It has 5V 2.1A rating compared to 5V 1A on the provided charger and it charges faster by 1 hour +/-
I'm glad that they didn't implemented fast charging, fast charge damage battery. My recommendation is to use 1 amp charger like stock charger because if you use 2 amp charger you will damage battery, if you use 0.5 amp charger, you will damage charger. 3 hours is enough for me.

Not really fast quite slow to be honest, apparently they didn't sell the mobile with fast chargers, they could have just added a couple pound on top like any other manufacturer and add a fast charger.
It's worth noting that the charger it shipped with will charge the phone somewhat faster than other chargers I've tried, charging the device at about 1.9 mAh vs. 1.5 mAh for a standard charger in my tests
That said, it's still not what most people think of as a modern fast charger.
If you want 0 to 80% in 20 minutes, this is not the phone for you. ?

Xiaomi 65w charger

Is it ok to charge my note 20 ultra using Xiaomi 65w pd charger
If it supports fast charging... but the phone power controller will still limit it to the phone's max fast charge rate... if it can communicate with that charger.
The 45 watt fast charging rate may decrease battery life as well.
