Charge speed I'd say is good considering the battery size. ~ 2 1/2 hours for full charge according to my screen tests so far, and that is while using it too.

Especially when you wait for first full charge to complete before turning it on ?

ya, after the first charge its not so bad.

Battery life is great, and idle batter loss is minimal compared with last two tab s's I'm not complaining about charging speed

Charging the Tab S4 takes me 3 - 3 1/2 hours for me from 0% using the stock fast charger from the box.

Qc4.0 or qc3.0

Not sure how fast it charges but since I can never drain the battery completely in a single day (usually at 20-30% by the time I go to bed with heavy use), I turned off fast charging and charge the tablet while I sleep. It`s always fully charged by the time I wake up and hopefully turning off fast charging increases the longevity of the battery over the course of a few years.

Might be QC 2.0/3.0. Can't really pinpoint it since I returned the tablet.

Samsung adaptive fast charging is 5v or 9v which is a partial implementation of QC 2.0

Yes, typo on my end. I've corrected my post.

Just tested with usb voltmeter from ali.
If screen is off then 9V, 1.5A (fast charge).
If screen is on - 5V, 1.5A. Not bad also, but can be better

Hmm just bought one of the 12v 2a Samsung chargers, don't have a volt meter so can't test but wonder if it has the same issue...

12v is for their wireless charger

Charging with the original Keyboard Cover
The charging time is normaly ok. But when the tablet is in the keyboard cover it takes a lot of time. More than 12 hours.
Any idea?
Thank you for your answer.

Got same problem... Don't know why. Any sensor maybe?

I find I have to switch my Tab S4 OFF to charge otherwise it will take all day. Switch it off and it charges from empty in arouns 2.5 hours.

Personally I don't have QC enabled on any of my devices. I plan on buying the Korean 256/6GiB LTE version to replace my Note 8 in the next 2 months for visual/screen usage reasons. Since I don't believe in letting the battery drain below 30% (it's better for devices), I will be charging it normally without QC to see how it fairs. Typically devices are shipped from factory anywhere from 50~80% charge state.
Though not to mention that having a "to spec" charger and USB-C cable is important for proper QC function if you're using that.

I have done some testing.
With QC 2.0 (my old Motorola Turbo charge 15) I charge phone from 20% to 90% with rate 65%/hour (1 hour and 10 minutes time)
With QC 3.0 (charger and cable from original Chinese packaging) I charge phone form 30% to 87% with rate 95%/hour (40 minutes)
I think this scenario is common for most users when they need to charge phone in hurry.
Later I will add also charging rate for quick wireless charger included in box and maybe also some QC 4.0+ if I get my hands on some.

In my case, I bought a PD3.0 charger from Aukey and my Mi Mix 3 is charging from 0% to 100% in 1h08 !
In fact after a few research I found that Power Delivery Technology is compatible with Qualcomm Quick Charge because Quick charge is working with Power Delivery and add a few security technology, but power delivery already have some.
Nevermind, I tested it and indeed My PD3.0 charger (max 15V and 3A) with a anker cable wich support up to 5A is working faster than the QC3 charger !
I suppose a QC4.0 should be better, but for now I think PD3.0 is the best solution !

I second @romain1672...I've converted all my chargers to USB-PD since I've divested from non-USB-C devices and my Mi Mix 3 flies with them.

I believe the wireless charging is relatively slow, think one review said three hours for full charge? But that's expected to be honest.
I've heard it said that slow charging is better for battery life, so in effect, wouldn't the wireless charger be better than cabled, if you're not pressed for time?

It took me exactly 1h45 to charge from 17% to 100% with the wireless charger. It's pretty fast for a wireless charger, but the only issue is that it heats lot of more than wired, and i read somewhere that heat isn't good for battery health.

Hi guys, I just bought the Razer Phone charger (it's the only one I could get quickly with Quick Charge 4.0+ in the UK). Not the most scientific of tests, but it went from 30% to 87% in 30 mins. I tested from 30% again today with a Quick Charge 3 charger and in 30 minutes it made it to 80%.
Sorry I didn't run from 0-100%, I can probably test that more easily this weekend if people are interested?

Fast enough that for the first time since owning a smart phone I never have to think about looking for a charge, even when travelling.

Does anyone know of any wireless chargers/charging stands that charge the mix 3 as fast as the included one? I've tried a couple I had with previous phones and they just charge so much slower

This charger is becoming annoying.
I place my phone on the puck by my bed. Sometimes, before falling asleep, I hear the sound indicating charge stopping.
Then, in the morning I find my phone has moved off the puck. And it is not me! The phone slips away if not perfectly aligned centrally on the puck. It is not surprising as the induction forces between the puck and phone will be opposing but the manufacturer should have spotted this and made the puck/phone with more friction between them.

Bro, I use my brothers Samsung Wireless Charger "EP-NG930" from his S8. Google it to see it. I can't post a pic of it since I leave it in the office but underneath it is rated at 9V 1.67A (15W)
I must say it charges pretty much the same, if not, faster than the included one since it has a built-in noiseless fan behind the coils

I agree. Best hands down. Not sure about longevity of the battery with such fast charging. But... seems pretty unreal/amazing this far.

its normal for huawei to preserve battery life span.... other phones do the same they just display you 0% when there is still juice left

Ah ok never had a Huawei before only Samsung wnd didn't know

Beast on both ends.. charging and battery strenght..

Does anyone know shat charginspeed is used when charging over USB-PD?
If I connect the wireless charger to Huaweis a 22,5 W supercharger => it charges but it does not fast charge over wireless charger
If I connect the wireless charger to USB-C PD desktop charger that is capable of 60W => the wireless charger shows fast charging exactly as it does when I connect Huaweis 40W supercharger

Charging is slow myvphon

I don't use charger supplied with the device; I don't require to be charged this fast.
At home I'm using Anker's wireless charger. It's connected to Anker 6 port charger and I think it charges with about 10W. Works fine overnight.
At work I use generic wireless charger connected to Anker's 18W QC3 charger. I think it's 10W too, although I cannot be bothered to calculate it properly for both; I don't charge USB charge meters so this would be difficult too since phone doesn't give all the data, only charging speed in mA.
I need to get some better charger for the car because my current one, paired with 2m cable, is supplying barely enough juice.
When I tested 40W charger supplied, it's pretty nippy - I'd say just over an hour to get from 0 to 100%

Mine takes about an hour and 15 minutes from zero

Mine takes around an hour and 15 mins to charge to Full.. Really impressed with the speed.

Hi.
I want to know how much mAh does it show on when charging ?
I used many chargers even the 40w one and it can not goes over 3300mah
Now with 65w supervooc its 3400mah.
Does it the max ?

Not the absolute fastest around, but damn sure not the slowest... especially when you consider how much further every 1% of battery will take you on this phone compared to other phones in its class. Fast charging kills batteries anyways, so I charge slowly most of the time since I'm always around a plug these days. I really wish I had this phone back in 2011 when I lived on a bicycle and was always on the road away from home and/or power. My only other gripe is that I wish there was a software switch to turn off fast charging like Samsung offered. Sometimes I only have a fast-charge enabled charger around, but would prefer a slow charge.

I don't slow charge in the traditional sense, but I use a QC 3.0 charger for the same reason. It maxes out at 3A to the battery, or 0.6C charge rate. It's still plenty fast, but slow enough relative to battery capacity that it doesn't stress the battery much and no need to worry about turning a setting off in the phone.

Im using 25w adapter PD to charge V60, charging speed is too slow, need above 3hours from 10-100.
Checking battery in hidden menu, saw charong current max is 1,7A, usually lower.
Normal adapter give me same speed (like a cheap samsung fast charge adapter).

I am having the exact same issue. Have you found any solutions yet? I am about to either return the device or change the battery and charge port. Although, I am not sure if it will help because it has 10 watt wireless charging and still maxes out at 6 watts on wireless.

iam using Xiaomi 33w adapter with a Baseus cable, dont use Xiaomi cable (with red color inside usb port, this cable hold 5V only) .
This combo charing my V60 fast (about 1h30 -2h). Its acceptable for me.
Now i dont mind about charing speed anymore.

Hey bro i hqve a 36 watt fast charger. I noticed that my phone charges in 1 hour 40 min before. Now it still ahows me 1 hour 40 min but it takes hours to charge..... It is still showing fast charging. It never happened before

Got it down to 0 today so did a test. Bear in mind I'm also going through a UK plug adapter the vendor supplied
I put the phone on wired charge with their supplied cable and plug at 16:03
I stopped out for some beer. Came back and checked the phone at 16:30
It was 100% charged. If the marketing waffle is wrong it isn't by much! A day's power in half an hour? Try FULL power in half an hour (with time to buy some beer!)

Is there anyone that knows or has been able to find which charging speed the phone supports when plugged in to an ordinary USB-PD charger?

20v PPS up to 55W.

Shouldn't even have to say it. We all know it's incredible. 40% in 5 minutes, 100% in 22ish.
