I updated OTA to Pie last week, since then it seems my charging speeds have got much slower, taking maybe twice or three times as long. Fast charge is enabled in my settings.
This is on all my chargers, wireless, wired and car charger. Anyone else had this problem?
Unusual for a software update to cause that, does the phone actually report that it's Fast charging?
Edit: Download Ampere and measure the charging speed. Mine reaches 2540 - 2640 mA at 70% charge on a QC3.0 charger for reference.
Try wiping the Cache Parition in Recovery Mode. If that doesn't help, try using a different cable and charger,
Occasionally unplug your charger, disable fast charge.
Plug in charger should show lower charge rate maybe 1100 mA to 1800 mA
Then disconnect charger, re enable fast charge, plug in charger,
Should show 2800 mA approximately

I am never getting more than 1200mA (according to Ampere app). Not with samsung cable, not generic cable nor wireless. Most of the time not more than 500 or 600.
Of course, I cannot compare to what I was getting before Pie update because I never measured the charge then.

I haven't used Ampere app,
My figures came from

Although I would expect very similar figures if accurate

I seem to get a longer battery life (first step down from 100%) if I charge my MDA C4 using the supplied charger as opposed to a charge from a PC using the USB lead.
If I charge using the charger, and just use 2G, I get approx 14 hours before the first drop in the batterymeter. From the PC it happens well before 11 hours.
Is this possible or am I just imagining things?

To get full capacity phone needs 5v 1000mA (= 1A) input, which is the charger outputs. If the PC USB output cannot pump that amount it might last shorter....
a PC's standard USB port only outputs 500mA (0.5A)
i think the supplied charger may be 2A (cant check atm), i know the official HTC Car Charger is 2A.

My original HTC charger (Model: TC P300) outputs 5v 1A
Interesting. I'll check the HTC charger when I get home.
However, Would this not mean that it would just take longer to charge the battery?
(Analagous to having to fill a bucket of water from a 1/2" bore pipe as opposed to a 1" bore pipe).

What I did notice is that charging form USB takes much longer than charging off the wall.

It will do, should not effect the overall charge (as long as it is left long enough!)

Correct, actually water analogy is quite often used here
yes i thought that...
phone charge lasted longer with the mains charger than the usb on pc
and usb pc takes ages to charge full
So I guess we'll all be using our wall chargers now? As the charge is faster and some believe better!
Make no sense to me as to why the charge of the PCs USB cable is not as good as from the wall....
However the slow charge time bit of it makes sense
Car Charger
I have huge problem with my car charger. I use Noname USB car charger, that worked perfectly with my Trinity. Now, when i connect my Diamond it sometimes connects and disconnects the device to USB twice in two seconds and so if the battery is low message about battery fklashes in an out. SOmetimes it does not happen and the battery is charging normally. When i start IGO8 while battery is full and Diamond being charged, it sometimes LOOSES power and after couple of hours it gets out of power even when charged. Sometimes it doesnt happen and the device is charging properly, but very very slowly. When i turn device off, it charges normally. I tried two different chargers and get the same results. But none was HTC original.
It's irrelevent how the phone was charged. If the battery is full, then its full ,and it will last the same period of time irrespective of how it was charged.
Charging rates will vary depending on input current, but once the touch sensor light stays on, then the battery is full.
Hey guys, I just bought my One a couple weeks ago and I'm loving it so far. However, I'm having an issue with the USB charging speed.
I know USB charging speed is slower than wall charging speeds, but the speeds I have been getting are ridiculous. To charge my phone from 0-100 takes about 9 hours over USB when the phone is in sleep mode and not being used. Can anyone else tell me if they're getting the same kind of extremely slow USB charging speeds? Is this normal for the phone? I've been thinking about replacing it and seeing how the next one fares.
I'm charging in usb 3.0 port and takes 5h

I haven't timed it, but yes USB charging is very slow in general and especially on this phone. I've had several HTC Ones, and had the same experience.

Some Kernels have an option for fast charge which is supposed to help with it but certain usb ports only put out a certain amount of power. Also I know a problem with the OG note was with fast charge enabled a few charging ports burnt out (mine included). It was easy to replace them on that phone but this one will be more difficult if it does the same thing.
The problem is that the phone sees the difference between an AC charger and a usb charger. With an AC charger it can charge with a maximum around 850mA while with an USB charger it charges with an maximum of 500mA.
There properbly is a trick how to make the phone think it's on AC charger, while it's actually on an USB charger, and therefore charge with a higher current, but I haven't found out how yet.

Depends on the current battery level of the phone. Anything above 83%(somewhere around there), even on AC charger it will slow down to 500mAh at most.
I recently ran an app called Ampere and it says my battery is charging at 3.962 volts at 1030 M.A. Shouldn't it charge around 2000 M.A.? Was wondering if the app is accurate or what are some of your charge rates
Using the Oem charger and cable
My phone charges (while off) from completely dead to fully charged in about an hour and 15 minutes.
Something is wrong with your cable/charger. The official fast charger will quickly charge to about 85% then trickle charge afterwards to 100%

The maximum amperage is determined by which charger you are using, what charging mode you are in, and how full the battery is.
If you are using the Note 4 OEM charger with fast charge capability, take a close look at it. You'll find that in fast charge mode, the maximum amperage is 1.67 A, not 2 A. So, 2 A isn't even possible in a properly functioning OEM charger in fast charge mode.
You will also see that, with fast charge mode turned off, the maximum amperage is 2.0.
Confused? Many are, because we have become used to the notion that, in order to increase charging speed, the amperage needs to be increased. And that is true, so long as the voltage remains the same.
But, when you look closely at the OEM charger, you'll notice that in fast mode, the voltage is 9 V. In regular charge mode, it is 5 V. So, the charger achieves faster charging by increasing voltage, not amperage. Why does this work?
Math.
Power (in watts) = Amperage x Voltage.
In regular charge mode, 5V x 2A = 10 watts of power to the battery. Not bad.
But, in fast charge mode, it's 9V x 1.67A = 15.03 watts, a 50% increase in power to the battery.
Why your battery is pulling 1.03A @ 3.962V is not really clear without more information. As mentioned previously, there are various reasons for your scenario, but in no case can you achieve 2A input to the phone when in fast charge mode.
Try discharging your battery to, say, 20%. Then, look at your numbers again. You'll discover that, as the battery's charge increases, the amperage will decrease. 4V and a little over 1A is what I get when my battery is about 75% full, and it decreases rapidly from there.
My N6 is no longer fast charging and is slower charging over all.
I bought a new turbo charger, tried different cables, rebooting and everything I can think of short of a factory reset. It seems to be a hardware problem with the device but I could use some advice here. I installed a Play Store app called Ampere which is showing a maximum charging current of 650 mA which I'm pretty sure is well below what it should be.
Just doing a back-up now in advance of a full wipe, though I don't think it's software related.
Any thoughts?
are you charging via being plugged into a wall outlet or via usb?

while usb and wireless, thats a normal amount of voltage, but for a wall charger, if below 90, its not quite enough. normal would be from about 2100-2400mA. but, since about 4 months ago, my phone stopped fast charging as well. but i still get more of a charge than you. honestly, ive no idea what causes it. my guess is that its something with the usb.
Just to update- I RMA'd my device this morning with Google and they're sending me a replacement device. It became clear it was a hardware problem with the USB port when I hooked it up to the PC and the N6 wasn't detected.
Just a note to anyone else with this issue. Check what Ampere says. It will give the mA, which is useful, but it will also tell you if it detects charging as "Turbo"
Indeed, Ampere was showing 'Normal' rather than 'Turbo' on my device.
ill try it when i get home as well..
Got my new N6 and everything's good. Ampere is showing 'Turbo' mode and its charging around 2000 ma. Much better than 70 mA, lol.
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?
---------- Post added at 09:53 PM ---------- Previous post was at 09:49 PM ----------
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)
