[Q] Nokia Wireless charger continues charging after battery is full

I bought a Nokia wireless charger from ATT online store.
It works on my nexus 5, but when the phone is full charged the LED light on the charger is still solid on (on means charging, and blinking means done). However I go to Setting->battery, and it shows battery is full.
My question is which one is right?
-Wireless charger is still charging the phone.
-The system shows battery is full, so the phone won't be charged. But since the charger is Nokia, so it doesn't know my Nexus 5 battery is full.
Thanks in advance

I believe there phone will stop charging the battery buy the charger won't know so it'll keep going. The phone has the circuitry to prevent damage to the phone.

I purchased (2) tylt wireless chargers from kickstarter a while back and I planned to keep the N5 cradled most of the time.
Unfortunately while the chargers work great they also heat the battery to 110 F while charging as compared to around 80 F with a straight USB charger. I'm afraid this heat will eventually kill the battery. Since the battery isn't easily replaceable I've decided to abandon the wireless chargers.
The batteries and the whole device stays hot after its charged and until I pull it off the charger. I didn't notice whether the charge light actually went out on the charger itself after the charge was completed. If I'm brave or (dumb) enough to try it again I'll report back.
Anyone having better luck with the stock wireless charger or other wireless chargers like the Nokia?

I purchased the same Nokia wireless charging pad, and, despite the LED not turning off on the pad, the battery DOES stop charging once it is full.
This can be observed through a battery monitoring app like Battery Widget Reborn. If you look at the battery graph at any point after the battery hits 100%, and before you remove it from the charging pad, you'll notice an even 2 or 3 percent drop and rise at regular intervals. This is the trickle charge mechanism. Once the battery is full, it stops charging, Once the battery drops down to a certain percentage, the charge resumes, and the cycle repeats itself until you take the phone off of the charging pad.

Same here with another brand on wireless charging pad, I think it's normal

Are you not concern with premature battery wear considering now it's not user replaceable? Heat is supposedly not good for battery life.

Fast charging issue

Hello my estimated charging time seems to be not working properly? It says Fast Charging @70% Estimated Charging Time 43 mins.
What's your estimated charging times? at any percentage so I could gauge mine if it has issues. Thanks!

I dont think this is a problem. When the phone is very low like 10% or so and you plug your charger in it will charge you up to around 50 - 70 very fast indeed. Once the phone is around 70% it then starts to slow down to a regular charging pace.

When I plug in my phone it says 1667 mA, after a minute it goes down to 1300 mA. Why is that? Using Galaxy Charging Current app

For starters you are leaving it a lot of info, like what is the battery level when you are doing that. Also while the screen is on you might show less of a charger rate than with the screen off.
Kinda weird but when I use a BlackBerry tablet charger (1.8A with 6ft fixed cord on them, have a lot of them for $4.99 ea) I get 1800mA which is higher than the charger that comes with the phone. I never use the charger that comes with the phone as a result.

XZ's battery charge time is 2.5 hour from 25%, is it normal?

I turned on battery care mode.

Battery care is turned on?

Mine also came with a slow charger. When I plug it to my portable battery, it can still be pretty fast (and hot...)

With stock UCH 12 charger it takes my phone about 1,5h to get fully charge. 30min to 60% and 1h for the rest. It seems like Sony disabled any type of QuickCharge above 60% to prevent battery damage and it doesnt matter what type of charger you would use alter that - it will stick to 1000mA all the time.
Two things:
1) are you using QuickCharge charger?
2) do you or any of your apps use phone while charging?
Any of those would prolong charging time.

Please see my answer are listed below and thanks
1) are you using QuickCharge charger?
Yep.
The charger is UCH12.
2) do you or any of your apps use phone while charging?
No.
I turned off the phone during charging.

Try to keep it turned on then. I guess Sony could set offline charging to minimal settings and control QuickCharge with software. Try "Ampere" app to check how many ampers are you getting while charging (download from play store, no root required). It should oscillate from 700mA to 2500mA. If not (e.g. stuck at 1000mA) it means your charger could be defective and should be exchange for new one.

man. I got 75% in an hour while the phone was off :/ using the same charger as yours so there must be a problem, try to change the cable

Guys does anyone know if the USB type-C cable which comes with the non-fast charger is 3.0 Quick Charge compatible?? I've ordered a Anker 3.0 Quick Charge charger just wanted to make sure the cable is.

My case is even worse, tales 3 hours to charge from 13% to 97%
I am even using the newest Sony 3A usb c to c quick charger!
What the hell..

XZ support QC 3.0 so it should be able to charge from 0%(theoretically) up to 100% 1h40-1h50 using a QC 3.0.
During my few weeks i've had this phone (recived with UCH20 charger) i tried to test phone's ability to charge quickly and failed it took usually 2-2h20 min with original charger. I've ordered chinese charger (sony's UCH12W is 4 times more expensive, even samsungs and htc chargers are much more cheaper).
During tests (using ampre) i tried to start charging when battery dropped to 10%. I used 2 charges original UCH20,Tronsmart WC1T and 3 USB-C cables 1x original, 1x unknown chinese, 1x tronsmart(original included with a charger).
Conclusion:
UCH20 is slower, Ampere won't show more than 1560mA 10-60/70% then something around 1100mA and 780 or less 90-100%
WC1T is faster, 10-60% 2220mA (or less depends on throttling/temperature) then about 1500mA to 90% and less than 1000mA (usually 500-800mA) 90-100%
Tested with onvo adaptive charging on, stamina off, wifi on, brightness auto (0-40%), there was no difference betwen cables only unknown chinese cable was slightly slower but that is only my opinion. Battery temperature oscylated between 26-37/38°C(Ampere)
This phone will only fast charge up to 60/70% then it slows down a bit and last 10% is slow, it should preserve battery health yet still allow you to charge it quickly when in a hurry so u can use it for another few hours until you'll get back home and plug it for a night.

Good post, thanks for sharing,
I ve recently brought Anker PowerPort+1 charger QC3.0 compatible and used stock Sony cable and max output I got was 2180mA max using Ampere too.. What my question is now what should the XZ be drawing max? near 3000mA?? Battery care Off.
Ive ordered PortaPow 20AWG cable it states its also QC3.0 compatible so lets see how much it get and if it makes any difference to the charge times.
I will post my results in the next 2 days.

Charging speed

To power up, you consume Red Bull. But your phone just needs its adaptive fast charger. Rate this thread to express how quickly the Samsung Galaxy S8 can charge. A higher rating indicates that it charges extremely fast.
Then, drop a comment if you have anything to add!

I got problems with it...
Sometimes it charges really quick, like Quick Charge does. But then sometimes it says it needs about 8 hours to charge fully.
Thats why i voted Average 3* and charging speeds sometimes even differs if i plug it out and in again.
EDIT:
With the original charger which came in the box it works fine and needs about 1h and 40m to fully charge.

1 hour 45 mins normal charge with original cable and adapter S8 rocking stock AQF7 not rooted

OK, the original charger, what is the Voltage & Amperage Output?
Also.....
From 25% to full charge using a QI Wireless Charger and the Original Charger that came with it, how long to full charge?
From 25% to full charge using the USB out on a laptop (.5Amp), how long to full charge?

Hi are you Iranian?
If you doesn't use official Charger of S8 that it's available in Phone Box it's probably correct that your device will not be charged very fast and you have to use the Official and trusted charger of Galaxy s8 that Samsung electronics have confirmed it.

Been using the s8+ for two weeks
Not sure what to say. When i check with Ampere app, it only shows it charges for 1000 maH
I have Xiaomi mi5 which charges for 2000-3000 maH with the same charger
How could samsung lose to Xiaomi?

After the August security patch the fast wireless charging is broken. I have the European version S8 and a choetech wireless fast charger. Does anyone has this problem after the last OTA update?
Just to point out, the fast wireless charging option is activated in the settings but the wireless fast charging is not working, only normal wireless charging.

I was wondering if it was my wireless charger faulty... did you have any source on this bug or it's just your (and mine) experience?

you cant check charging current with ampere app, because Samsung changed charging method a lot after explosive s7.
basically if screen is on charging current drop to ~ 1000mah. and phone use 9v or 12v only if screen is off.
also if you phone charge longer than 2h something is wrong with your charger\wire or phone can't go to sleep properly due to "cancer" apps who prevent full sleep.
But iam here to ask owners of 25watt chargers, is it worth it? how long it takes to charge it with it?
i not sure if link are allowed here but here it is https://www.samsung.com/us/mobile/m...apter-for-galaxy-tabpro-s-25w-ep-ta300cweguj/

Question What's causing this(Samsung Wireless charger EP-P5400)?

It's about Samsung official 15W Wireless Charger Duo (model number EP-P5400) and is the fastest wireless charging pad from Samsung.
Using the above wireless charger, charging the S22 Ultra(Snapdragon) using the 25W Samsung adapter and the cable(that comes in the phone box) . Started charging at 12 noon when the battery was at 1% and in about 3 hours 21 mins it's charged till 76%, and to fully charge it took 4 hours and several minutes. The "time remaining to fully charge" shown below the battery icon is false, it takes way more(double) time. It does fast wireless charging at 15W, but should it take 4+ hours to fully charge?
This charging adapter+cable combo does super fast WIRED charging and charges fully as intended and on time, so no issues with the adapter+cable.
Phone FW build is "AVCJ", phone is not connected to any bluetooth device or such, there's no metal object in between, fast wireless charging toggle is ON in settings, cache erased in recovery, device care app version 13.0.03.1(is the latest and app cache erased), phone restarted and so on for basic troubleshooting.
What is the issue if not the EP-P5400 wireless charging pad itself?

Bump!
PS: Ambient temperature is low (21/22°C), so it's not about slow charging due to temperature rise in the phone and the cooling fan inside the charging pad is working fine too.

This I've already mentioned in the OP.

some possibility is that the phone was doing something in the background that consumed battery while charging... check to see if anything is running in the background, often times it's Google related (some 3rd parties known to drain are FB related apps)
If this is doing all the time then might be something that you'd want to check with samsung. reproduce the issue then report to samsung using Samsung Members app > get help > error report.

Have you tried a different wireless charger. Yours may not be working correctly for some reason.

I did, with a 9W wireless charger from Samsung from 10 to 30% that took comparatively longer time than this new one, which is obvious.
Dpk1 said:
So, today it charged from 53% to 100% in just 55 minutes. Phone wasn't used while charging and 4G data bluetooth were on like before. Charging was done at similar location of the same room as before. The difference was that I used Samsung 25W adapter to power the Wireless Charger (instead of hp one) and kept the charger over a flat wooden rack (instead of over bed mattress last time).

Charged from 53% to 100% with the above "conditions" met using the 25W Samsung adapter. Started charging at 9:40 AM and done at 11:11 AM, that's 1 hour 31 mins.
What's the device care version you are using?

Just for a test unplug the pad from the charger and hook up direct to the phone with cable. How long does it say for a charge now?
I have the 15 watt Samsung Charger that comes with a 25 watt super fast charger. 15 watts wireless and 25 watts when wired. EP-P2400TBEGUS make sure when buying the one I have that it comes with the travel adapter (Charger). They sell two versions one for $39.99 that is just the pad only and then the one I have for $59.99 that comes travel adapter (Charger)
Anyway I am currently at 45% let me put it on charger and see how long it says it will take to charge to 100. Ok it says 1hr 9min to fast wireless charge to full.
Now I plug in the cable direct to the phone and it says 45min to super fast charger to full.
There is no way phone shoukd take hours to wirelessly charge unless there is a problem with the pad, charger or case interfering with wiress charging.
What case are you using? Are there magnets on it? Is it very thick material?

Hence, charged it when phone was turned off, "gain" was some 8 mins less time to fully charge. So the problem lies elsewhere.

Wait I missed that post above. You said you used an HP Charger and a Samsung Charger on the pad but the Samsung wirelessly charged in an hour and a half wirelessly? What's wrong with that?

Also where and what is the wireless pad sitting on? Wood Table or Desk? Not a bed?

I just did 33% - 100% in about 1 hour 18 min which is pretty normal for 15 watt fast wireless charging. The same Samsung 25 watt charger plugged in wired will get you there under an hour. Don't use third party chargers with the wireless pad. Just the Samsung 25 watt one. Really nothing wrong with 1.5 hours wirelessly. These are normal charge times.

Yours same one does, mine does not same way wirelessly like yours. That's the problem. Nothing else.

After about 80% the charging rate ramps down to protect the battery.
At about 90% it will ramp down again and likely yet another time as it approaches 100%; this is normal. New batteries have a higher capacity and will charge longer.
Peak charge rates occur between 6- 72% or so as long as it doesn't exceed about 102F.
Fast charging will not engage for that charge cycle if the start temperature is below about 50-60F or less to protect the battery.
Ideal start temperature is 82-90F, charging is an electrochemical reaction that needs enough heat to function at optimum fast charging rates.
Provide cooling as needed as temperature approaches 98F.
Other possible causes are a defective temperature sensor in the battery, mobo or charging coil. Firmware; corruption or wrong values. A defective coil assembly, C port pcb or mobo.
