with 27W Charger the phone charges from 0 to 55 percent in about 30 mins and 0-100 percent in about 1Hr 15-20mins.

charging speed depend on battery temperature. fastest charging if temp below 35 degree C, around 3500-3700 mA

The charging speed is damn fast.

Please Notice Me
Hello sir, are you using a flashed global rom?

Guys what about 27 watt sonic charger? Is it worth to buy?

charging rate is very slow when i use the phone while charging....its around 1200mah

Are you serious? My 18watt Charger that comes with the box takes 30mins to reach 50% and takes 1hr 25mins for full charge. Then why 27watt??

in my stock charger it charges 44% in 30mins and 1hr 30mins to full charge. Difference is only about 20% while it should be 50% more faster as 27W is 50% more power of 18W.

You are correct. Difference is just around 20% which is not acceptable.

i've decided not to waste money to buy the 27w charger after watching this..

I have two power delivery charger both capable to charge up to 60w. When I connect phone to both charges doesn't matter which one and which cable I use currently it always display fast charging text and icon. Why it doesn't go on turbo charging? If I know the phone support qc 4.0 and PD and it should turbo charge on my chargers, right? Anyway I noticed 3300-3600 mAh however it doesn't really look charge as fast as in reviews.
Some people reported 4A but according to qc 4.0 specification it's rather about 3A at 9A. What's the real charging voltage for our Xeromi?

It seems Xiaomi uses a proprietary protocol for it's 27W Turbo charge. For now I've not seen any other charger capable of charging it on 27W other than the Xiaomi one.

Chinese people are used to lying. Phone doesn't support qc 4.0 and doesn't weight 190 g. It weight over 200 g (200.5g)

The phone charges at 300-500ma when using pubg even when using a 18w qc3 charger which normally charges at 2800ma. Anyone else facing this bug?

Nope i didn't seen it but mine working great i have usb tester so i can check everything about charging i didn't seen charging at 0.5A
Your saying it charges at 2800ma but this is working actually at charges at 9V & 2A so 18W charging but those ampere & accu battery are showing differently. First i thought they are genuine after i bought USB tester I learned a lesson they are wrong

I tried a Belkin 27W QC 4.0 charger(attached), Macbook Air 30W original Charger and one more 45W Type-C charger.
But non of them shows Turbo Charging. Not even the Quick Charging message comes up when using the original 18W charger.
Saw this charger on AliExpress with a seller who had feedback saying it gives Turbo charging.

Do you have pubg installed & would it be possible for you to check charging current while game is running in foreground please?
Also btw my charger also has a 5v&3A mode so that's why it was showing ~2.8A

It's not a bug i guess... Its a OS thing .. some custom rom uses the force fast charge option... Then the phone will charge fast even we use the phone or play games.. but in stock roms they disabled the force fast charge thing... So when in idle, phone charges around 3000mah but when using the phone it comes down to around 1000mah or even lower while playing games

2 Hour With Stock Charger
I didn't completely check the ratings and time but stock charger DOES NOT fast charge this phone. as the Stock Charger isnt QC2.0 Supported. However this mobile does support QC2.0 but you'll have to test QC2.0 Charger 1st. Not all QC2.0 Chargers work on this mobile. Its a little picky. So go to a shop check QC2.0 Chargers on your mobile. when you get circle Sign on notification bar along side battery then it means that device is fast charging. if not then there will be no circle around the charging sign (Flash sign)
also idt this mobile supports QC3.0 but i dont have tools to check amps volts of charger.
Lenovo's original QC3.0 charger doesnt work on this phone. I've tested. but Motorola's QC3.0 Charger works fine.
my rn5 pro , takes apporx 3 hours to charge completely!
So far I'm a bit slow, a little bit more than 3 hours to completely charge the phone. Might have something to do with the cable.
My current charging setup:
- ANKER 5 port 40W
- a docomo USB cable
Planning to buy a proper 20AWG usb cable and a QC2.0 adapter.
I just bought a Letv charger which supported qc3.0 for about 4$ on taobao
I'm currently on the 9.5.11 build and it takes about 4-5 hours to completely charge the device using stock charger, And it took about 2-3 hours while on 9.2 build.
I wonder if the Mi QC 3.0 based charger would improve the situation for us?

Slow charge is a known bug in 9.5.11 build. Wait for an update or change ROM
13,2W for me
I recieved 9.2.13 update yesterday and have been noticing significant boost to charging speeds since then...yet to fully charge from 0 so can't comment on total time but as per Ampere, charging speeds are in range of 1500 to 1700 mah
1000 mA max with 5v 2amp and Work Normal Speed with Stock Charger
Approximately 2 hour for charge phone
I use the app Ampere (free in Playstore) to measure power input and with a normal charger (non QC) it shows up to 1600 mAh charging amount and from almost 0 to 100% it is taking 2,5 hours. One question: is there a way to tell if QuickCharge is active?
@Kusie
Look on your"s phone status bar. With normal charging there is thunder icon next to the battery. With QC active, thunder in in circle as far as I remember. Info about active QC should be also displayed in the bottom of your lockscreen
Sent from my flo using XDA Labs
Using my usb inline meter, i'm getting ~6.5v and ~2.2A, with a Tronsmart usb cable and QC 3.0 Truro charger, screen off and about 44% remaining on battery. Will try when the battery is lower some other time.
takes around 2hours to charge 100% using stock charger..

I have no idea why would you do that... But read reviews, no matter what kind of charger you use, this phone only supports qc 2.0 version. From 0 to 100, in 1 hour, you only get like 55%, and in the end it slows down even more, so yes, impossible to fully charge in 1.5h, TECHNICALLY IMPOSSIBLE. You are either lying, or mixed times and got confused. Judging by technical parameters, the best this phone can do should be around 2hours from 0 to 100.

I just posted above that I was able to get QC 3.0 charging rates. Approximately 2.2A (fluctuates +/- 0.1A) and 6.6v (fluctuates +/- 0.2v) using a QC 3.0 charger and Tronsmart cable. Measured using an inline meter, not software.

takes about half an hour or so as far as I can remember 8/10
Charges really fast, thanks to 18W charger. Although on cable connected to computer, very slow

From mathematical standpoint 30 mins for 0-100% is impossible with 18W charger, let me make it a bit clear
It has a 3.800mAh battery or 3.8Ah for short, which means if it had a 5v 3.8A charger it would take 1 hour if the charger and delivery system(cable+chips inside phone etc) were delivering 100% efficiency. Now 5v 3.8A is 19W charger. For half an hour we need 5v 7.6A or 38Watt.
According to Quick charge which is present in this phone it can be charged at 9v 2A or 18W, so even if the phone has 100% efficiency it would take a bit more than 1 hour to complete 0-100% but because each system can't deliver 100% efficiency calculate to 1hr and 1-20 mins give or take
P.S. half an hour, wish but ain't possible unless we have 9v 4.2A charging with 100% efficiency(or 5v 7.6A if you prefer) - Still going to get this phone soon(if price drops to my desire)
Just charged 25% to 100% took around 1 hour
I have here the test i made 100% to 11% took 6h34m SOT, charging from 11% to 49% took 25 minutes from 11% to 82% took 59 minutes, from 11% to 98% took 1h36m.

Drained it fully so it died...
Then 0 to 53 % in 35 mins flat...
I think the last 10%( from 90 to 100} takes a big effort.
Just tested with LG V20's Fast Charger of 18W.
Fast charging works. confirmed.
But not with OnePlus 3T's Charger.
Will check the same with 5T's Charger and Update.

Yes OnePlus 3T, 5T does not work.
Also I was charging N7+ from 18% via LG V20's Charger and it got overheated and started malfunctioning. But thankfully there was a circuit breaker and protection circuit in LG's Charger which saved it. Device is working fine too. Now I am using the nokia charger provided in the box as none are working.

So that means if something happens to the current charger provided with the phone, we will have to buy a Nokia branded charger and cable or there would be issues. Hmm

I also meet this using oem cable. With nokia original cable is no issue.
I just got this device Thursday not a Dual SIM device
It charges fully in about 1hr and 30mins of charging adds quite a bit of power to the battery
if we use a PC it takes ages
is it safe to use fast charge daily?
Can we charge the device by a standard charger having 5v 1 amp rating with the USB type c cable plugged into it?

Yes, i use mine from a tablet at 5v and 1.5A. You can use any charger if it is 5v or if it is turbopower o fastcharge.
I also use my old LG's charger. 5v @1.8A. Im not really that into charging speed. One thing i noticed is that on both chargers when reaching 100% it says charged but still charges for another 15minutes before the charging icon (flash) disappears from the screen. Has anyone else noticed this?

This phone charges pretty fast! Around 1h 35min from 0 to 100% (I think, will test that later). I'm using the 30w charger.
2 hours with 18W
1 hour 40 mins with 25w charger...
Any one used some charger with 45/50w? ;D
I want to know how much faster this smart can charge lol.i bought the 30w charger and i think is very fast a great smart too
I'm having serious issues with 3 of my Samsung 15W chargers. Never had a problem with LG G6, Samsung S6, S7, S9 and the odd device here and there while on Rog Phone 2 it will quick charge 1/20 times with it.
And believe me. You don't want to charge with the regular 5V charger mode. It will take hours upon hours.
Maybe it has something to do with the latest OTA.
If some1 can test 50 / 65 w charger and post the results will be awsome!

Which 25 watt charger are you using
I'm facing issue with my Rog 2, my phone is not charging fast. 1) I'm using 18w charger come with the phone to charge. 2) I have used Xiaomi 2i power bank with 18w output to charge my phone (still not working). 3) When i restart the phone battery goes down 36% to 29%. 4) On charging when i restart the phone it goes 8% to 13%. 5) I'm facing this problem from the 2-3 days. 6) Double plus sign on battery icon as well as fast charging text on home screen is also not showing while charging

It's a custom made charger bought from ebay. It is called JUICEBITZ Turbo Charger 3.0 Qualcomm Quick Charge 3.0 3 port.
Normal charging speed, just like 4000-5000 mah phones batterys from 2013 same speed nothing special.
6000mah what more u expect ?

You need a higher output powerbank bro.. I bought a nubia 27w output power bank to be closer to the 30W power brick...
I use my Note10+ 25w charger. Works well.
I tried Baseus 60w PD type-c charger but it's charging about 16w. Looking for 30w alternate charger. Asus one really expensive with our local money.
1 hour 40 mins with 25w charger...

QC 3 is great, I dont use the wireless charging.
I'm honestly pretty disappointed with the quick charging speed. I had the Essential phone before this and loved the 27w fast charging with USB PD. The G8X charges really slow in comparison. I've tried QC 3.0 adapters and USB PD adapters and just can't find something that I would call "quick" by today's standards.
im using a xiaomi remi note 8 pro charger to quick charge, the one in the box doesn't give me "Fast charge" icon
using the stock usb-c charger, I get pretty good fast charge. wireless is a bit slower but I use it to avoid fast charge anyway to preserve the battery health.

I agree. It is unstable charging. In my cause power ( A) is jumping, also QC3/unknow is swapping very ofter. Just connect USB meter. Strange. There is an option for save charge, but On/Off causes no difference to me.
ive tried 5 different chargers but this phone does not charge more than 10w on any chargers QC 2.0, 3.0 AND 4.0+ usb AtoC CtoC tested on usb tester. it will spike to 13w maximum then go stable 10w all the way. Can anybody test on their phone to confirm this? ive tried these chargers on xiaomi and realme phone they would charge upto 17w
Lg g8x charging speed
Tried every charger starting from 15W and up to 40W. QC 3.0 to 4+, Dash charge, Warp charge, Super charge, Adaptive Fast charge. 0 to 100% takes 2 hr 12 min.
LG g8x refuses to charge faster with any of them. When world moves to faster charging protocols incl. long hesitant apple for iPhone, LG does the opposite. LG and Qualcomm mentions that QC 4.0 supported in their official websites which should support 27 W, but with any charger phone accepts max. of 13 W in my testing.
I have been using LG phones for long only because of quad DAC. For people like me who wants to support LG, this slow charging is a real issue.
I understand that V60 comes with 25W qc 4.0 inbox charger which charges 0 to 100% in around 1 hr 45 min for 5000 mAh battery as per YouTube reviews.
Now the only question left for me is that can 25W V60 charger be used to charge g8x battery of 4000 mAh in 1 hr 30 min. Has anyone tried charging g8x with V60 charger? If so, can some post changing time.
I would really like someone to use Mi Pocket Powerbank Pro available in India a 22.5 W Quickcharge (don't know which Qualcomm level, guessing QC3) powerbank specifically using a super high quality cable either the Blauplunkt Flat USB 2 to type C or the Ikea Type C to Type C cable using the type C Power Delivery (PD) output port of this powerbank which I believe would be the topmost setup ever for charging this device. Is the Max fastcharge rating 18w of this device?? As such I did not even mention Redmi 30w powerbank. Which is the QC4 power adaptor or powerbank which can be bought in India?
If rooted you can get fast charging via a magisk module. It charges fast even with screen on... Which is what annoys me about the phones that restrict it to approx 1000. They still limit temperature to 46C
Turbo is 2750mah, super turbo is 3000mah
Normal is 2450mah and 45C limit.
Also recommend the intelligent power control magisk module, better than acc. I'm using 90 max 86 back on. Works great!

It helps where keeping the screen on, the charging speed is not reduced. Before this, keeping the screen on would reduce the charge rate a lot.
Now I'm on s21 and they severely limit charge rate once the battery reaches 37C.

Yes, I have with genuine A71 charger ( already in use with my A71 ). Huge difference then this supplied 15w one.
I never let my phone to go to 0% as it effects battery life. Usually get it charge from 15 to 100% and it takes exactly an hour .
15w (supplied in the box) does the same in 1 hour and 50 mins approx...
Highly recommended to have a 25w original one... ( There are lots of copy versions in the market which are of no use as they charge on same slow speeds).
To verify, its simple that it will show "super fast charge" and the copy version will show only "Fast charge" which is not fast by any standards....
Mine from 1% to 100% takes about 115 minutes
about 1hr to go 40-100 on a 60w laptop usb c brick
With 25w charger it charges 18-20% in 10 minutes.
It's decent but I do miss the dash charge from my one plus.
Seems mine charges rather quickly no issues.
