Get a good cable!
I have a Xiaomi Redmi 4x, which mounts the same battery as the Note 4.
While charging with the original cable my mobile reached temperatures of about 40 degrees.
As soon as I changed it for a better cable, temperature dropped 10 degrees.
Xiaomi's advice is to remove the cover if the temp. reaches 42/43 degrees.

My device too .. reaches 44° C while charging with original charger..

Yes it heats up because it's taking in 2amps, not because of the damn cable.

Charging speed

To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the honor 5X can charge. A higher rating indicates that it charges extremely fast.

Takes almost 2 hours with me using a 2.1a fast charger

if you have gsm battery app you can see that the phone cannot accept 2.1A,
it's the big cons indeed!
Takes 2h20m from an Anker IQ 2.4A charger (1-100%) With the stock 1A charger it takes 3+ hours.
I just got mine and it charges much faster with a 2 amp charger. I am using a 5 port Aukey with one port that has the Qualcom fast charge 2.0.
I also have a Blu VIVO 5 and the Honor charges just as fast as that with the 2 amp charger. The Blu Vivo 5 includes a 2amp in the box while the honor does not.
On my HTC One and my Sony Xperia Z3 compact, https://play.google.com/store/apps/details?id=com.gombosdev.ampere reports something in the neighborhood of 1.4-1.7 amperes with a Quick Charge 2.0 charger, and I go from 1% to 60% in about 20-30 minutes as claimed. On my Honor 5X, the highest I see the app report is 850 mA, and it takes about as long as what everyone else is reporting. With a non-Quick Charge charger I get about 550 mA.
Edit: 850 mA is what I often see using one of my chargers. I'm using a different one right now and just now I saw it as high as 1.1 A.
Using an USB multimeter I can see it charge at 1A with my Blitzwolf 5 ports charger.
Honor 5x L22 model take around 3 hours to charge from 0-100%.
Wish they would enable Qualcomm Quick Charge tech for this device since the Chinese market version has it by default. It takes quite a while to charge from 0-100
Good speed with the normal 2 Amp charger. reaches 100% in and around 2hrs
Quite slow
upto the mark
Coming from a fast charging phone, honor 5x is quite slow. But it is OK as i use the phone normally so from 100 to 0 it last easily 2 days.

yep they should have used some sort of quick charge
0-100% takes 2 and a half hours usually.
2hours with 2A charger
It's still very slow
Plus side is slower charge will keep your battery in better health and longer lifespan . fast charge is real harsh on the battery pack .
I find mine takes almost 3 hrs from about 5% to full when on and 4G running . You can get 60% in an hr or less which not bad .

VOOC from Oppo is the most efficient.
2 hours average from 5-100% on stock charger.

Took me 3hrs to fully change my Mido. 0-100%
3-4 hours for a full charge, this thing really needs fast charging feature to charge this huge 4100mha battery..
Me too 3 to 3.30 minutes.If we use it while charging it charging slowly .
My phone take around 2 or 3 hours
2-3 hours as well, but I just charge while I'm sleeping. It easily lasts the full day, so I don't need to charge during the day
Charging RN4 mido is damn slow. It takes around 3hrs for 0-100% topup but why complain when the device lasts for 2days with 10+ hrs of SOT.
Anyone tested charging speed using a kernel that supports fast charging?
My phone takes around 2-2h30 hours to fully charge.
10% to 100% --> 2 hour 50 minutes
2.40 min if on if off around 2.20 if off
is there by any chance to enable fast charging on this device?
My phone takes around 1-1h30 hours to fully charge. Am from Brazil, here uses 230vts in my region...

Get a micro-USB cable that is 22 AWG or lower (the lower the AWG rating the better). And make sure that the cable is made by a high quality manufacturer.
Charging Time
My Phone charges from 0-100 in 2 hours maximum.
Excuse me but charging Redmi Note 4 with STOCK ROM from zero % to 100% takes minimum 3 hours using the cable and charger from the box.
On stock rom I think it's impossible to go under 3h. What is Your take on this?
3 hours to fully charge my rn4 mido. If this device have quick charge it would greater than it is now

The stock charger doesn't come with quick charge, just buy qc charger that is 3.0 (I suggest Aukey qc) and you'll get atleast 2 hrs charge from 0-90%.

Enhancing charging speed

Hi..
I just watched a YouTube review about Xiaomi Redmi 4 Prime which have nearly the same specs to our beloved Xiaomi Redmi Note 4. The reviewer was suggesting to use 3rd party Quick Charger 3.0 to enhance the charging time from 2 Hours 32 mins (with bundled charger ) to 1 Hour 40 mins (with QC 3.0).
I don't know if that is true or not also if the QC will harm the battery on the long run???!!
what do you think?

Quick Charging is not enabled by Xiaomi on our device

Not enabled as of now however , I believe its a feature available on all Snapdragon 625. So it definately work if someone builds it into a custom rom.
PS I dont know why REDMI n4 is missing it. If i plug in my moto turbo charger, it charges at regular rate, however if i use a turbo charger on redmi 3s prime, it charges fast (Rather screen also shows "charging quickly" or something)
OEM charger, charges Redmi Note 4 faster in 2 hours when battery is at 5-10%.
I tested many other chargers of 5V and 2A output but only OEM (came with phone) charges faster..
i still dont get why there's always ppl that wants to charge this device faster. you charge the phone for 2 hours and some minutes to get 10 hours SOT 3 days charge, yet still wants to charge faster.

Slow Charging

Hi guys . My phone is 20 days old.Today I suddenly noticed that it is charging slowly.So I downloaded "Ampere" apps.And it show current maximum to 450 ma and averege is 250-300 ma.So I replaced the cable with my friends lenevo cable.Then it shows 850-1050 ma.But somewhere I read that it should show minimum 1500ma.
And another problem I am facing with my mi charger.It is a disconnecting often.But the Ampere apps showing charging current after disconnecting.
Plz read my problem carefully and suggest me what I have to do.
And what charging current are u getting in " Ampere "apps.
I am eaxausted with this problem as I faced the same problem with redmi prime 2 and I sold that phone.But I don't want to sell RN4 as it is beast in performence and I love my phone.:crying::crying:
I am using miui global 8.5.8.0 with original mi charger.
It happened to me too, but my phone is over 6 months old, i checked in ampere it was showing only 300-400 mah.. So i changed the cable and it catches only upto 1100 mah, previously with mi cable it was showing around 1500-1600 mah.
I think u need to buy new cable which have high speed.
It changes all the time.
It always take two and half hours around.

Download ampere app from play store and check the input current if it more then 1200mA + then its fine it not then something is wrong. Try with different cable.
PS : I normally get 1500mA to 1800mA

Redmi Note 4X charge with 20k Xiaomi powerbank

Previously my Redmi Note 4X charging with 20k Xiaomi powerbank for overnight, when it is fully charged, the powerbank will off the power.
However, recently when I charge my phone overnight until full, the powerbank is still charging, my phone charging light is on, and battery monitor widget also has log to shown that its charging eventhough battery reached 100%.
Does it will harm to my phone number for overcharged ?
