Mi4i features fast charging. Can you suggest a better charger than 5v-2a charger?
Apple iPhone charger shows up as a fast charger for me.
fast charging is supported but the charger in the box is a normal one. (5v2a)
can anyone try out with the proper fastcharge2.0? (9v1.2a)
Donnt have one...would definitely love to get the feedback from someone who tested it first hand!
how do you see it 'shows up' as a fast charger?
are there any indication?
Mi4i FAQ http://en.miui.com/thread-122548-1-1.html
50. Does my Mi4i have Quick Charge feature? If yes, then which version does it support?
A: The Mi4i has Quick Charge 1.0, which explains the slow charging rate some users have been complaining about. The Mi4i takes roughly 2 hours 30 minutes to fully charge for me

And FYI, http://www.gsmarena.com/charge_test-review-1239p2.php
Quick Charge 1.0 was introduced in 2012 and it made use of a 5V/2A charger, which could charge a phone up to 40% faster than conventional 5V, 1A chargers. That boost accounts for a 10W max charging power.

Thus the original 2A charger that comes with phone is the fastest charger supported.

Yeah
Any charger compatible with Qualcomm Fast Charge 2.0 is good for Mi4i . Go for it..........Do verify this before buying
Hi
I have a charger from a broken Umi Zero is a 5v 2,4A, can I use it for charging the mi4i ?
thanks
Hi,
I'm not sure, if Mi4i really support QC 2.0 but the chipset does.

Xiaomi Mi 4c Charging Analysis Part-2
I just bought Tronsmart TS-WC1Q and I must confirm almost the same results as with original Xiaomi charger for Mi4i. Charging current with Tronsmart charger is about 1,44A and voltage is stable about 5,2V. I'm not sure, if I can determine from these results, if its support QC 1.0 or 2.0. Next time I will try to measure the time from 0->40% of battery and compare original and Tronsmart charger. Anyway I think it matters also on the ROM/kernel you are currently using. I'm on RESURRECTION REMIX with Sensei kernel v1.3.2-dev kernel.
I m on cm13, it looks like qc2.0 is supported. I used a China charger (9v1.2a). It charged fully charged up from 0 to 100% in 1hr and 40 min.
i have tried
i have tried qualcomm's fast charging 2 it works well.
How fast is Mi 4i supposed to be? I've bought orico quick charger 2.0 and it does about 1.5 hr to be fully charged. Do I need to install something to make it faster?
I've seen on different post , many said it can charge max 1.5 A. or 1500mAh .
but i'm not getting that charging rate , tried out different 1.5 A. and 2.1 A. charger. on Stock Rom/Custom Rom/Kitkat rom.... nowhere.
I've found max rate on
Amphere: 930mAh
Battery (apps): 1120 mAh.
plz post here charging rate of ur one.
**sorry for my english
Plz reply this post buddies..... i need info cause my MOTO G Takes maximum 1100 mAh or 1.1 A...

I have tried many chargers , currently using a 2.1A charger - full charge in 1 hour.
I think amperage of falcon is around ~1.5A
Apart from the charger the quality (esp. thickness) of the cable also matters. I have used bad quality thin cables with 2.1A charger and it takes more than 5 hours to charge - so I bought a high quality charging cable

Hi, i've just purchased Xiaomi mi 5 and i have question regarding charging the phone. It supports Qualcomm Quick Charge 3.0 however the charger that was provided only supports QC 2.0.
I notice that whenever i plugged the phone to the charger that supports Qualcomm Quick Charge, my phone gets hot. I decided to do a little test, so I used an USB Charger Doctor that can read voltage and Amp that it delivered to the phone. I've also using Ampere to monitor my battery temperature. I'm gonna charge for about 36 minutes using Aukey charger. It has 3 ports with only 1 that supports QC 2.0, the rest of the two supports up to 5 volts at 2.4 amps.
Here's the result:
9 volts, 1.35 amps = 56% battery charged from 8%. Battery temps reach 43,2 C. Juice added, 48%.
5 volts, 1.71 amps = 43% battery charged from 7%. Battery temps reach just about 35 C. Juice added 36%.
It's clear that qualcomm quick charge is faster than the standard port, however it resulting in higher temps. And i know the fact that Lithium batteries hate high temperature. So which is the best for battery life? Higher Voltage lesser Amps, or Lower Voltage Higher Amps? Thanks in advance.
Has anybody measured the charging rate of the S8 Plus? More specifically has anybody checked to see how many amps they're charging at?
I'm using the app called Ampere and I'm only seeing a max of 1 amp regardless of what battery percent I start charging at.
This seems really bad considering this is suppose to be fast charging. On the pixel I was getting 2+ amps at all times. On the nexus 6p I was getting 1.8 amps.
Can anybody else also check to see what you're getting. Please post what the battery percent is at when up plug in to charge, and what the app Ampere is showing.
I am using original charging brick and original usb a to type c cable.
When the screen is on fast charging is disabled, when its off its charging at [email protected] from 0 to maybe 70% then it trickle charges.
With standard 2A charger, i can see 1600-1700 in ampere,
With QC 2.0 , am checking the voltmeter and it do the 9v charging,
So nothing wrong

No, i mean any decent 2A charger,
I use my country local brand Hippo, for example, and charging rate is good
The one came with the phone is QC 2.0 that can go faster than normal 2A charger, although it only rated at 1.67 but it's 9V
So this is what I've found out.
First of all the app Ampere only gives charging information for when the screen is ON and not OFF. I uninstalled the app and installed AccuBattery which does everything.
When charging with the screen on the phone charges with amps of 1.3 amps.
When charging with the screen off the phone charges at 2.5 Amps.
Again all original utilities used

This is interesting and annoying at the same time. I had no idea the phone charged at different rates based on if the screen was off or on. my previous htc 10 did not do this and charged fast anytime it was plugged in. while driving and running waze i noticed the s8 didnt charge as fast with the screen on but ill have to try with it off to see the rate. i also installed accubattery to test screen off charging rate since ampere doesnt. thanks

Well I drained to 60% and recharged and on fast charge i got 1.5 amps or 1500 milli
I go off my cable it has never let me down
I have had to many device where the readings of the apps where off
That current cable is pretty accurate most apps I have seen on S8 though
I use it to detect charging problems on blocks,cords,and device Found the sweet spot on my old note 2 with it and made it usable for now again

It variates up and down a bit seems pretty stable till i turn on screen
So I bought a very cheap cable at the 'Action' (a discount store in the Netherlands) and I didn't believe what I saw.... 2.7 Amp, with SCREEN ON. I tested with 3 apps. It IS really the loading amp.
Unbelievable !! THe cable can be inserterd in 2 ways (everybody knows here, USB-C) With the label on the cable up works the fastest. I think charging with phone off goes even faster, till 80 %, maximal 45 min. Is this an update of Android for the S8plus or do I have an extremely good cable ?
Hey guys, just to let you all know on my findings. I have Nexus 5X charger (rated 5v 3A) and decided to try on my A1.
It goes from 63% (I think, I forgot to write down the actual %) to 100% in 45 minutes. Considering usually after 80% it will charge slowly, I think this is pretty quick time.
I'll test it again some more when the battery level is much lower and report back.
I'm on latest Oreo stable
OPR1.170623.026.7.12.29
are you measuring the charging amperage after 80%?
37% in 45 minutes isn't all that fast, imo.
I'll measure charge time tomorrow, stating start percentage and I'll look for what happens after 80%, to see how much it drops in charging amperage.

I didn't measure it's amperage, just check the time till it fully charged.
If do the math from this charge means from 0% can be fully charge in 82 minutes. That should be faster than stock charger. One caveat though, if it's really 63% and not 73% when I start charging it.
Now my phone already 2 hours SOT and almost an hour hotspot, but still left 74%. Not easy to deplete it's battery.
One more thing I forgot to mention in first post, I'm on latest Oreo stable.

From what I read, Quick Charge would use dynamic voltage (5v-20v) instead of utilizing higher amps to attain higher wattage charging.
Use ampere app to measure current.
For better results try charging it while its off from 0 to 100.
And try while its on.

Ok I'll try it when I charge later. Now the battery still left 50%. I'll drain it another 10% at least before charging.
its still same as before.
only below 2A
Sent from my Mi A1 using Tapatalk
Alright so my battery was at 42% when I plug in the charger. Using ampere it stated Max USB Curr is 2000mA. And the reading max is 1930mA while average is about 1800mA.
After 20 minutes it have gone up to 65%. Reached 90% after 43 minutes. At exactly one hour it reached 97%, which I checked ampere reading is 440mA. 100% reached at 64 minutes.
During charging I received a call which lasted about 3 minutes, which I use loud speaker for the call, so here might have added few minutes to it's charging time.
So I guess the speed is around the same when Oreo beta is?
Start time: 0805h
Battery: 38%
Check in time: 0905h
Battery: 87%
Did see that the amperage has lowered to around 1A after the battery reached past 80%. It definitely decreases after 90%, I'll check this the next time I charge.
I can run the test again with a different usb measuring tool. This first one seems to indicate a lower voltage than my other tool by about 0.2v (and amperage by about 0.2-0.3A. Although it should just be a passthrough for the power, it may be inhibiting the power sent to the phone.
The measured amount of power sent was ~1600mAh to get the phone to 90%. That seems about right for 52%, give or take.
i try with Honor 8 Pro QC charger (9v 2a) and it goes from 0 to 78% in 60 minutes, phone was off. I don't know the total time to 100%, sry
Stayed around 1400 mA for me above 80%

1600mAh is the amount of power that was sent to the phone, as measured by my USB measuring tool. If you're talking about amperage during charging, I get around 1.9A on average. It fluctuates between 1.85 and 1.95A, and the voltage fluctuates between 4.95 and 5.20.
This is using a Tutuo charger which is capable of QC 3.0, and also 5v/2.4A.
I've tested using the regular 2.4A port and the QC port.
Basically, this phone does not request more than 2A at most, so even a 3A charger isn't going to make a difference.
I am using stock charger only. Don't have fast charger won't buy it unless phone supports it

Looks like it, it won't accept above 2A. I want to try with 9v 2A charger, but after 24 hours and 2.5 hours SOT, the phone still have 75% battery.

How much mA you get from ampere when using the stock charger and batter is less than 80%?

1700 mA -1900 mA +-50mA
Edit: since you are trying so hard.
From what i have read few years back when i had xperia zl
Incase of zl max current was capped at 1.5 A
QC 1 is 5V 2A our charger 10W
I bought Samsung 5v 2a charger for my zl. I still have it. Works fine. (Just adding history to context :laugh
QC 2 was designed to give 18W(average)
5v 2a QC1 compatibility
9v 2a QC2 18W output
12v 1.67a (from Wikipedia)
QC3 went with higher amps and dynamic voltage
Don't know anything about QC4
So give 9v 2a a try while measuring current take screenshots multiple times to track voltage since i don't know any other way to measure voltage except what ampere already shows.
PS: i know commands to read from proc and all but since i haven't rooted my device i won't ask you to go through that way.
I used lenovo charger which support 5v-2A, 7v-2A, 9v-2A and 12v-2A
Started charging 12:54 AM, battery at 4%, airplane mode activated
and these are the results

I tried with 9v 2A charger, still capped at 5v and almost 2000mA.
One interesting finding is using the 9v and Dash charger plus their cable give consistently almost 2000mA, whereas if using Mi charger and cable; or Dash charger and Mi cable; or Mi charger and Dash cable; all give around 1700 to 1800mA averagely. I think Mi charger and cable is of lower quality and unable to max out 2A.
The conclusion that I found is if want a slightly faster charging then use other better quality charger and cable.

That's as fast as when Oreo beta is. Like I suspected Mi original charger and cable unable to max out the ampere.
Thanks for all the hardwork???
This thread should be locked now and made into sticky.
Cause this is nothing short of a research on fast charging in Mi A1.
Hi There,
I just read that Mi has not opted for Quick Charge by paying royalty to Qualcomm. So they have disabled QC functions from software side, though chip is definitely capable.
By Mistake, they let Beta have QC functionality. But now that has been fixed.
We now have to find way to enable it ... If possible.
