What will be the charging speed if I use a 45w or a 60w charger
The phone locks it's self to a specific out of the box speed , i mean u have google pixel 4xl and it's a advertised that it's 18 w fast charge , do even if i put a 100 w charger it would take 18 w only , that's why the have Power delivery technology , it's for the communication between the phone and the charger about charging limits , i thinks samsung has 25 watt charging speed so you're stuck on that , nothing can make you go beyond 25 watts except changing the phone to another brand wich has another fast charge technology or higher advertised charging watts

Having issues charging with the original charger since 8.1. When I was in beta 8.1 the charger stopped after 5 seconds same when phone off and charging it just kept rebooting to charge screen. So rolled back to 8.0 and all fine. Now have 8.1 again and the charger has stopped working again. My Nintendo switch charger charges phone fine on 8.1. So is there anything I can try to see why 8.1 has stopped orignal Nokia charger Woking ?
The Nokia charger charges the Nintendo switch fine
Same
Same with me .. Need answer from the expert
Yeah same, mine charges now and again ? and at only 1.5amps! Weird because my QC Charger ramps up to 3.0amps!
I bought the phone four days ago, TA- 1004- Global Dual SIM. Immediately updated it to 8.1. From yesterday Nokia's original charger charges the phone only at 1.5A...
What app do you use to check the charge rate?

Try to close developer options in settings. Probably USB debugging could be an issue. Turn it off.
Yeah it's werid my phone charges full speed for a bit then slows down to 1.5ah
I believe Ampere is not really accurate together with QC. Used a small USB multimeter once and there you can see that the charging amperage during quick charging is not much higher then about 1.4A.
One of the characteristics of QC is that the voltage during charing is boosted. At 'peak power' the multimeter showed 12V & 1.4A, thus charging at almost 17W instead of the 'normal' 5V & 1.5A (7.5W).
Hi i am new here so forgive me
i have been checking the QC from beggining and it seems at 9V i get 7V and 1.44A and seems its a new type of battery that works this way at 4.3 volts instead of 5v at 1.79 get from other phones with a 4.2 volt battery.
changed charger with 5V 2.1A and it still went up to 1.44 .
i think the default charger is the only one to use.
i get a day and a half with fb and games seems that it doesnt get hot

Agreed, standard charging is at 5V, QC 2 jumps up to at 9V and QC 3 jumps up to 12V but Ampere's voltage reading doesn't seem to reflect these boosted voltages.
My old Samsung S6 (from which I just upgraded to the Nokia 8) says "fast charging" when QC is active vs "cable charging" at 500mA (e.g. when plugged into a very old charger or PC) vs "charging" at other non-QC rates... I had assumed this was an Android feature that the Nokia 8 would have too, but apparently not, which is rather disappointing. Perhaps it's worth a feature request in the official Nokia.com forum for the N8?

Correction: Looking at Ampere again, the voltage appears to refer to the battery, not the incoming power, it only shows the mA for that, not the voltage. So I'll log a feature request for Ampere...
UPDATE: My phone is model TA-1012, I'm currently running Android 8.1.0 with build number 00WW_4_84A_SP03 and I've noticed that the phone DOES tell me if it's quick charging, but only on the lock screen when it's showing notifications, and only as per the following sequence:
1) Directly after plugging in to any charger it says "charging"
2) If it's plugged into a QC2.0 or QC3.0 charger (and using a compatible cable) then after a while (not sure how long exactly, seems to be about 2 mins) this changes to "rapid charging"
3) After another while it changes to "charging (XX mins until full)" or "rapid charging (XX mins until full)" depending on the type of charger (and cable)
However, the phone is supposed to support QC 3.0 but the charging time estimate is always the same no matter whether I use a QC 2.0 or 3.0 charger, which suggests that it's actually a QC 2.0 device.
So i talked with Nokia support about the charging issue. They told me how to fix it...
1. Settings -> apps & notifications -> see all apps -> press the 3 dots in the up right corner -> show system -> battery protection -> storage
-> clear cache and data
2. Soft reset the phone.
How to do a soft reset: Press the Power button and Volume Up until you see "Powered by Android" on the screen. You can then release the buttons . Thats it.
its fast charging , it doesnt fast charge from 0 -100 . it works like this on nokia 8 : from 0-40 3amp , from 40-80 1.5amp , from 80-90 1amp , and decreases slowly from that.
but i have another problem , i dont have original cable and charger , my cable is anker powerline+ and my charger is xiaomi qc3 charger . my problem is that from 0-40 when its fast charging it keeps disconnecting and connecting every 10-15 sec.
BTW u can check your charge status when ur phone is locked (rapid charging = fast charging , charging = normal charging"this is from 80-100" , slow charging = somthing is wrong check ur cable or charger)
Wireless charging 2018 - Samsung Desk Top & Wireless Battery Packs?
What's up with wireless charging in 2018? Especially Fast charging.
I will usually start charging when the phone get below 15% of battery.
If my Fast Charging wire plug will charge my Note 8 in 1.50 - 1.75hrs........ the Samsung wireless Convertible will charge the Note 8 in 2.5 - 3hrs ..........and wireless Battery Packs like the RavPower and Kuppet take 3.5 - 3.75hrs to charge the Note 8 to 100%. (Even though the RavPower says it will output 10W.) This just seems like very slow charging technology. I am not on planes and in airports so I do not have times where I am without a power outlet for more than two or so hours.
If I was in airports and flying a lot the Kuppet would be a must have device with the 20,000mAh and worth $39.99 but just as a wireless charger it simply is to slow to be of value to me.
https://www.amazon.com/Wireless-KUP...eywords=note+8+wireless+charging+battery+pack
https://www.amazon.com/Wireless-Por...ote+8+wireless+charging+battery+pack+ravpower
Am I missing something here? I can fully wire charge my Note 8 in 1.5hrs at home, office and even car with the Fast Charging plugs. Why would I take almost double the time just to use wireless and buy those expensive ($40-$90) pads/stands?
What am I missing about the wireless charging value proposition?
Is the next step in wireless 15w output?
I've tried three chargers now and I'm only getting 1500mah charge speed at 60% battery
Original Nokia Charger 2.5ah Charge Rate
Aukey Quick Charger 2.4ah Charge Rate
Generic 2ah charger
Anyone else getting slow charge speeds?
You getting low current because Nokia 8 supports QC3.0.
Quick charge uses higher voltage than standard charing.
Current stays low, but voltage goes up so total wattage is higher.
1.5A x 5V = 7.5W
1.5A x 9V = 13.5W (same current, but double power)

But voltage doesn't increase charge speed, 1.5a would charge the phone in 2 hours whether it's at 5v or even 12v, my aueky charger can push 2a at 12v but it seems like this phone just doesn't like higher amperage.
As with all quick charge solutions the flatter my battery is the faster the charge rate, the fuller the battery gets the slower the charge rate gets.

You're completely wrong.
Battery is 3090mAh at 3.7V
This is total 11.4Wh - this is tells you much more about battery, as knowing current without voltage means nothing.
(for example power tools batters are 4000mAh only, but at 18V gives huge 72Wh of power to use, 7 times more than phone battery)
back to Nokia:
11.4Wh / 1.5A / 5V = 1.5 hour
11.4Wh / 1.5A / 12V = 0.6 hour
As you can se voltage matters as it shortens time needed to charge by almost 3x.
Obviusly in real life battery will not charge that fast as there is a lot of loss on heat, voltage conversion etc.

It definitely charges slower than any phone I've had ? my G5SPlus has a bigger battery and charges in half the time ? but like I said at any voltage it only pulls 1.5a from the plug so the 3090mah / 1500mah(ChargeRate) at any voltage from my 5v charger or my quick charger at 12v charges exactly the same 1.5ah which takes about 2 hours. In this case voltage doesn't make any difference in charge speed at least with my Nokia 8 device it never goes past charging faster than 1.5ah no matter what voltage the charger is.
Listen to TeddyBeers, as you are mistaken in thinking voltage doesn't matter.
At 5V and 1.5A, you have 7.5 watts of power to charge with. Assuming perfect efficiency, that means you are getting about 7.5/3.7 = 2A of charging current into the battery (at least, when the battery is sitting at around 3.7V).
At 12V at 1.5A, you have 18W of charging power. That means 18/3.7 = 4.9A at the battery.
The current through the USB cable does not matter, only the power! The voltage is converted inside the phone so that the battery charging current will NOT be the same as the USB current.
Hello. I tried charger qc 3.0 but doesn't work at speed fast... I tried the genuine charger with a tested cable hi speed 3.0 and doesn't work at speed... Can anyone suggest a charger and a cable tested working lower yhan 10 dollars shipped??? Its incredible this price difference with qc that i bought both 3 dollars
Use original cable and charger ro charge at high speed... Other cables or chargers don't work and can even damage your phone..
(for example my umi fast charger usb C..
charges at 5+9+12volts)
With a cheap price always comes cheap quality.
QC 3/4 are not built for the Mate 10 series, they are built for QC compatible devices, while it will still charge the phone, probably at slightly increased speeds - you won't get the full power out of it as, its not meant to be used on a Fast charge phone (Fast charge / SuperCharge whatever Huawei call it)
Let me share something which I've found out recently. If you use a QC charger for eg. Xiaomi Type C Mi Power bank Pro which support QC 3.0 charging, my Mate 10 will display "Fast Charging" which is definitely faster than normal "Charging". If you use the Huawei Supercharge AP09S Power bank, it will charge at the max rate "Super Charging"
Huawei Supercharge is a dedicated technology just like qualcomm quickcharge. For it to work you need the dedicated hardware.
Most important: Huawei Supercharge phone and Huawei Supercharge power brick. Since supercharge features up to 5A current you will need a type c cable that supports 5A. Then you are good to go.
The Huawei phone of course supports standard USB protocols like 5V2A etc. But that's not fast.
Older Huawei/honor phones support Huawei quickcharge (what they used before supercharge) which is 9V2A. I think the mate 10 supports that too.
From my experience though the phone displays "charging" when connected to PC via USB. "Quickcharge" when connected to normal wall charger. "Supercharge" when connected to supercharge wallcharger (or supercharge car charger or supercharge Powerbank) via 5A (ampere) USB cable.
hi guys, i'm from a 8 note and now i'm using sasung's original 8 wireless wireless charger to plow my new 9 notes, but i'm noticing that it's really slow, is it normal? I have the impression that even imposed fast charge does not change anything, do you have any suggestions?
im also using the wireless charger that I received from Samsung in 2018 for the note 8 promotion.
I can confirm that fast wireless charing takes 2 hours + on the note 9 and up to 3 hours when using slow wireless charging.
Also, keep in mind we have a way bigger battery so i am not surprised seeing these charge times compared to the note 8. I know Samsung released a new wireless charger so we might see better charge times on that??
I use the wireless charger I bought for my Note 4 for $12. It charges my phone in 2 hours from 50%, which is about double than using the cord. It doesn't say slow, or fast, just charging.
I use a Samsung wireless charger I had with a kit when I bought my S8+ and it says "Fast charging wireless" I believe. I use it to charge over night though so not sure how long it takes.
I use the ADATA CW0100 charger with Sony UCH10 QC2.0 Charger - the phone says it's fast charging but it takes about 3 hours to go from 11% to ~100% (with a clear case + bus card in between on the back). The interesting issue is which power brick I use. WIth Samsung's Adaptive Fast Charge power brick, I kept getting a charging paused error in the previous firmware, unless I have the phone placed in a very specific position without a case. With the update (N960FXXU2ARI9), it no longer gives me the error even if I charge it with a case, but the charging seems a bit more noisy in comparison to the UCH10 (there's no fans, it sounds like the inductor making a pulsing clicking sound). Will be checking its charging speed.
EDIT: I spoke to soon, it started the charging paused error again after I posted here. If you want to use third-party wireless chargers for fast charging, please use QC2.0/3.0 chargers instead of Samsung's own.
