Enhancing charging speed - Xiaomi Redmi Note 4 Questions & Answers

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?

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.

Feedback on Charging Times?

So one thing I I've heard is that the phone can be fully charged in 2 Hours, quite impressive as my S3(2100 mAH) takes 2 hours to fully charge whereas this phone fully charges 4000mAH in 2 hours.
Can the phone charge 0-30% in ten minutes? or something like 0-60% in 30 minutes or something similar?
nope, nothing like that. It does 0-40% in 1 hours, and takes 3 hours total. Its very slow.
My Galaxy Note 4 was really great, with about 90min. from zero to 100% but the Note 3 Pro need about 2h for 75%, the last 25% need about 1h, so 3h for 0 to 100%
I have 1.8A charger.. It was charging fast or 3h?
Here are two interesting user reviews about charging times.

I think I got 0 to 100% in 2 hours and 35 mins. 0 to 50 in 1 hour.

@exonerare I'm also using a S3 now and in thinking to switch to this phone.
But I think the charging times shouldn't really matter because from the XDA threads people are getting 10hours SOT (My S3 only gives 3~4) so i think its quite fair
It's been 2 days I am using redme note 3. Yesterday first time my battery completely got drained so, I plugged in for charging but it took almost 4 hours to charge just 2% and after that I replaced the charger with Motorola one then after 3 hours it was from 3% to 47% and then again I replaced the charger with Xiaomi one only then after 2 hours it was completely charge. So, what should I do guys should I go for replacement. I think something is wrong in battery.
From 10% to 100% about 2h30min with original Xiaomi charger that I got in the box.
Snapdragon version.
Quick Charge 2.0 would be great..
RN3 Pro 10% to 100% in 2hrs 30 mins - AOSP rom - original charger & cable
SD variant 32 GB,from 10%--->46% 1h;from 46%--->96% 1h;from 96%--->100% 20 min;i have tested both stock charger and this aftermarket/custom charger http://www.geekbuying.com/item/Tronsmart-Quick-Charge-3-0-USB-Wall-Travel-Charger-42W-1-and-2-VoltIQ-Ports-Quick-Charge-Port-Compatible-With-Quick-Charge-2-0---EU-Plug-363290.html.
Charging time is the same with both chargers
My phone is charging 20 to 100% in 1 hour 45 minutes is good or not can u please tell me?

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.
Sent from my KIW-L21 using XDA-Developers mobile app
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.

Mi 4 Qc 2.0 Hack ?

The guy here says the fast charge makes you full in 2 hours. Can someone please work for this? Because it takes 2 hours 40 minutes to charge on custom ROMs. : p
Here is link;

I'm actually getting pretty decent charging speed on LineageOS on mi3w. And on the lock screen it even says quick charging or something similar.
You may want to check your cable and charger again. Cheers.

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%.

will/do the Exynos variant support faster charging than s8, something similar to quick charge 4.0 or even 3.0? as on s8 adaptive fast charge is same as quick charge 2.0 so hope it will improve

I am sure they had mentioned it if they changed it...
Can anyone who has a Galaxy Note 9 measure it using an USB wattmeter or multimeter?
Does anyone know if the wireless charger that has just been released with the note 9 (the single pad not the duo) charges faster than the convertible wireless charger released with the s8?
I looked up the specs of the Samsung fast wirless charger pads that came out with the S8, S9 and the Note 9 on the FCC, and all 3 have the same power spec, so they probably all charge at the same speed.
The Duo that has just been released can draw more power, probably due to needing to charge 2 devices.

"Recharging the phone is fairly quick, too. We checked the battery percentage every 15 minutes, from 0% to 100%. We'll do it again before coming to a conclusion on recharge speeds.
15 mins: 17%
30 mins: 37%
45 mins: 52%
60 mins: 70%
75 mins: 83%
90 mins: 90%
105 mins: 98%
1h 49 mins: 100%"

why is Samsung insist on stucking in the past and can't move on.
quick charge 4.0, charge 5 minutes get 5 hours battery life. I wonder how many percent is that.

very true, Exynos are great but as they are not Qualcomm we are stuck with Samsung rebranding of Qualcomm FC 2.0.. great

1000000000000000000000x this.
Is the latest Quickcharge technology compatible with Samsung's 95% after 1 year battery promise? (Applicable to Note 8, waiting on confirmation for Note 9)
I'd lay odds on the feature being omitted for battery reasons at this stage.

So the Note 8 has faster charging than the 9? My response was getting at that QC has not got faster on the 9 due to Samsung maintaining the 95% promise, it might not be possible under a faster QC....
heard huawei announces put next-generation super charge technology on mate20, Samsung did no good on charge and battery.
It is actually so fast, it got me worried that i'd damage the battery. So i disabled it. Normal charging is fast too. (Faster than iphone 8 plus standart charger)

How is yours faster than the charging times I posted on the first page?

How do you check battery life?
Not satisfied with battery life and fast charging is a big joke besides my old p20 pro ???
People, don't forget, you're charging a much larger battery. It's not really comparing apples to apples unless the batteries are all 4000mAH. So, if you quick charge your 4000mAH battery, and adds 20% of battery power in 15 minutes, it added 800mAH, while charging a 3000mAH battery for the same amount of time will also add 800mAH of battery life, but will show that it charged 26% of the battery. IT'S THE SAME THING, and it didn't charge it any faster!!! A larger battery is going to take more time to charge than the previous Note 8 battery!
