Throughout a day I charge my Tilt from a variety of sources: the stock charger, my old Apache's charger, my PC, car charger, my Moto headset charger ...
Looking at them all the only difference I see listed is the amperage.
The Stock charger is 1Amp, so is the Apache's
The Moto charger is 550mA
iGo Charger is 1.5Amp
no idea what the PC or the car charger output is.
I am assuming that the differences in amperage would simply effect how quickly the battery charges to full. Is that correct?
Maybe also that a fully depleted battery would need a full 1Amp charger to begin charging ... the 550mAmp might not cut it for a fully depleted battery.
Would charging with a lower amp charger (550mA) or a higher amp charger (1.5A) have any long term negative impact on the charging or overall battery life?
Just curious ...

The amp rating is the normal maximum current that can flow from the particular charger. They all are spec'd to put out a regulated 5V but the current comes into play if you are using the phone at the same time as charging. If the phone draws more than the charger can supply then it's going to take longer to charge or may not fully charge. Normal charger is 1A and with that the phone can be used most likely at the same time. With a 550ma charger I'd turn the phone off (standby) to ensure a full charge in a reasonable time.
None should affect battery life, just time to reach full. The charge lite on the phone is your guide, when it's amber, it's charging, green it's full, simple as that.
The only thing that will harm the lithium is to take the phone to dead for long periods, that's the hardest thing on a lithium.

Carrier: ATT
Rom: AOSiP-V4.0-Marshmallow-6.0.1
Issue: Motorola Turbo Charger
Info: I have had no problems with the stock charger for the last year. Recently, when I plug in the turbo charger into my device, it will not charge. Usually in Ampere, it says it average around 1950 mA of charge, after the issue started occurring, it gives the charging icon but ampere and the built in battery meter says not charging. It actually decreases the charge at a quicker rate.
What I have tried but failed:
Restarting device
Changing Cables
Unplugging charger from wall
What has worked but is not a real solution:
It seems that the phone accepts the wall charger and charges normally after I plug my phone in to my computer via just the cable and then back into the main charger.

This honestly sounds like a outlet problem or a charging box problem. I would check both those if you have not allready.

My Nokia 8 shows charging on the lock screen and after few minutes it shows the time left to fully charge.
Just then I noticed my phone was on 19% and lock screen was on when I plugged in the charger. On the lock screen above the fingerprint icon it read charging rapidly and then it changed to charging slowly and went back and forth a couple of times, then went just said charging. I can replicate it 100%. Does what it says on the screen really mean it was charging slow and fast and fluctuating in between it?
Phone running oreo beta latest and using stock cable and charger that was supplied. Ampere shows 2910m.
What do you guys make of it.
From 19% to full charge the lock screen shows 3hours. Is that right for Quick Charge?
TIA
I have exactly the same experience with the supplied charger and other QC 3.0 chargers. I tested all the chargers in my house and found my old QC 2.0 Samsung charger is able to constantly rapid charge the phone. I have not yet been able to test of it is actually faster, will update when my battery runs out.
The same here.
I have a QC 3.0 certified charger and it is not showing fast or rapid charge. Looks like there is some issue with Nokia. It was exactly the same using Nougat.
Was able to do further testing and it seems the phone is quick charging with the supplied charger, or any other QC 3.0 charger. The supplied charger was 20 minutes quicker than my old Samsung QC 2.0 charger.
There definitely is a bug in correctly displaying charging rate when connected to QC 3.0 chargers. Also the charging estimates are about twice as high as they should be. The phone can fully charge around an hour and a half, but estimate states three plus hours.
Looks like a couple other people have noticed this issue on the Nokia support forums.
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?

Ampere https://play.google.com/store/apps/details?id=com.gombosdev.ampere
May be you can switOpen develop-model , then close usb debug model. maybe help you...

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)
Hi, so I'm having problems with my phones battery when charging. The phone charges to 100% in like 20 minutes, but when I disconnect it, the percentage drops to the actual percentage, i.e. 40%. This happens both with the phone turned on and with the phone turned off. And its easier to notice this when using the turbo charger.
I decided to check the charger output with Ampere and it tells me every charger I plug in delivers 5 Amps, which is impossible, as the Turbo charger has a max of 3 Amps and the other chargers I used where lower than 1 Amp.
If it helps, I'm on Stock Oreo, not rooted, and locked bootloader.
Is there any solution to this? I tried completely draining the battery and charging it fully, and it still happens.
