SuperCharge problem: defective charger or battery? - Huawei Mate 9 Questions & Answers

Hi everybody,
it's a few days I have weird problem with SuperCharge.
I apologize for the lenght of this post, but I don't want to miss any detail that could help in solving my problem.
I recently replaced the battery with a new original one (I hope) bought from an eBay seller.
When I switched-on the smartphone, battery level was 58%. So, I used it normally and, when battery level lowered at 30%, I plugged-in the charger.
Completed the recharge, I used the phone as always.
At night, with 30% of battery level, I plugged-in the charger and I went to sleep.
The next day, in the morning, I turned on the screen and the battery level was 32%. I was confused... So, I un-plugged the charger, plugged it in again and the phone needed just few minutes to fully charge at 100% (very weird).
Then I normally used the phone for the entire day.
At night, with 30% of battery level, I plugged-in the charger and I went to sleep.
The day after in the morning I turned on the screen and again the battery wasn't fully charged. It was only 34%.
This time I unplugged the charger and I restarted the phone. After that, it showed 100%. So, in reality, the battery was fully charged!
This made me think it could have been a software related problem: so, I performed a Wipe-Cache-Partition and a battery re-calibration process.
After that, I noticed the charging process was slower, although the phone shows "Super-Charge" in the lock-screen.
So, I wanted to monitor the charging process with Ampere and this is what happens:
- as soon as I connect the charger, for the first few seconds the charging rises to about 4000mA (as it should);
- suddenly the charging stops, as if I disconnected the charger. At the same time, the battery temperature rises for one second to 44/45 ° C and then quickly returns to 32/34 ° C.
- after a few seconds, the phone starts charging again, but at 1600/1700mA.
- cyclically, therefore, the phone tries again to increase the charging to 4000mA, but, as soon as it reaches the peak, the same phenomenon described above is repeated.
I noticed that the charger overheats while charging.
I replaced the USB-C 5A cable, but the problem persists, so it's not cable related.
If, on the other hand, I use a non-5A USB-C cable, the phone recharges in FastCharge mode (2A) without interruptions and the charger does not heat up.
So, the problem exists only with SuperCharge.
Do you think the charger is defective?
Or is the new battery defective?
I thank in advance anyone who will help me. :fingers-crossed:

I noticed a similar problem with super charge.. When plugged in for charging, super charge doesnt show.. It takes super long to charge to even 50%.. So i tried other cables as well and same issue.. I restarted the phone a few times and then switched it off.. Plugged charger in and left it over night. I noticed the next day super charge was functioning correctly

[Q] Keeps charging at 100%

Hello,
When I charge my Nexus 5, the battery icon keeps on showing it is charging even so the battery is at 100%. Also my USB charger (not the one LG one) indicates that the device is still charging. Is this normal ? Would this damage the battery ?
Thanks
It's normal.

Thanks ! (But i just find this weird as I expected a device to stop at 100%)
I understand what you're saying but it's not a charging icon, it's a connected to power icon. If you were to use something like the dashclock extension it would show that it actually stopped charging once it reached 100%
Thanks for the reply.
The thing is that I have this charger http://www.portablepowersupplies.co.uk/portapow-quad-usb-mains-charger/) and the LED indicates charging (albeit I did not measure the current ).
Nice unit!
Are you connected to WiFi while charging? I had the really bad battery drain issue while connected to WiFi after the 4.4.2 update. I lost about 30% of charge after 4ish hours while connected. Currently I'm at 92% after 3 hours.
The WiFi battery drain could be causing your phone to not fully charge or at the very least make your charger THINK it's not fully charged. No harm should come of it either way but it's always best to pull your phone off the charger once it gets to 99-100%
Thanks for the reply. I had Wifi activated; it might be the reason.
My wireless charger LED didn't shut off when my N5 was charged in a powered off state. Usually it does once the battery is full.
That said, I don't think it's over-charging the battery, as that would be really bad

Don't worry about it. This isn't the 2000s where constant charging is an issue.
Just tried with the Wifi Off. My USB charger then indicates that the unit is not charging.
Thanks for the replies and great help.
Don't worry about it. The charger isn't the thing that determines how charging is handled, it's all done on the phone side. The phone knows how to take and stop taking power.
In the case of the Nexus 5, it most-likely stops charging the battery but continues using the power from the charger to actually power the unit (thereby no-longer using the battery to run the device, but not charging it any longer).

Battery jumps from 11% to 22% once plugged for charging

Battery jumps from 11% to 22% once plug
I left the battery drain to 11%, well I did not want to put in on charge in the evening and left it till in the morning. As the title says, once plugged in for charging, the battery charging percentage suddenly jumped to 22%, than charging normally, a bit faster because I am using usb wall charger taken from Lumia 520, AC16X.
I removed it and used the usb cable that came with the phone, I do not think that is the problem with the AC16X, just charges faster
And one more thing, last time when I charged the phone to 100% I left it to see when stops charging, I mean, In spite of being charged to 100% still shown charging on the battery diagram window.
I left it 30 more minutes but nothing, I expect to see the word charged, but no, keeps showing charging…
It is normal?
Thanks.

Charging

I have not used Android in a couple of years so excuse me if this was an old feature.
This morning I was going to use the quick charger supplied by Google to charge my phone before I left for work. My phone was still in Do Not Disturb mode. When I plugged it in and it would not charge but it recognized there was plugged into a charger. It looks like it was just providing enough power to keep the phone charged at the current level (mine was at 60%). The second I turned off Do Not Disturb it started charging again.
This seems like a good feature. You can plug your phone in overnight it will maintain the charge instead of continuously charging the phone and potentially shortening the battery life.
You encountered a bug. I leave my pixel in do not disturb permanently and it charges to full. I have encountered the issue you describe and unplugging the charger and plugging it back in caused it to charge to 100%. It would be silly to tie charging to do not disturb as an actual function.
Probably just a matter of wiggling the wire. When the USB-C plugs are new, they can take a bit more than the expected amount of force to seat fully in their socket.

Charging very very slowly

Hello,
I have had this tabled for a while and it was always charging extremely slowly but I never took it out of the house so it wasn't a bid deal for me. However I have given it to my mother and she uses it in other ways. Anyways, the note 10.1 is the slowest charging device I have ever seen. It takes probably 48h-72h to charge it completely. I am using the original cable and power brick, I have tried ALL the outlets in my house, I have tried using the computer, I have tried using another cable (probably like 5 different ones) and other bricks (from iPads, my note 5, etc) and nothing is working. I have seen other posts regarding slow charging but none of them solve my problem.
Thank you
Thats is not normal .
I would factory reset and flash a stock rom .
Swap battery or take to a service centre .

"probably"?
You can't troubleshoot perceptions and guesses. How long does it actually take--repeatably--to charge from what percentage to what percentage? (i.e. "Went to bed, battery was at 40%, charged overnight for 7 hours and battery was at 60%.")
There are apps to check charging current (Ampere being one of them).
The fastest charge you can get is with the OEM charger in an outlet, not a PC.
Understand that this is a 7,000mAh battery without any quick charging applied to it.
Additionally, if you are using the device whilst charging it, you aren't really charging it since the drain is about the same as the charge; you'll effectively neither charge nor discharge.
Finally, check for battery-draining apps; you might not have a charging problem but an app-drain problem.

The time varies, but it is between 2 and 3 days to charge from 0, never less.
I do use the OEM charger and cable and an outlet.
I do understand that but 2 days seems a bit of a stretch, don't you think?
I am definitely not using it while charging, because it's impossible. It just doesn't charge fast enough to be able to use it. It drains quicker than it charges.
I highly doubt that, I only have YouTube and Chrome installed on it.
Above 6 hours with stock rom and charger is abnormal .
Usual replies .
One cable
Two charger
Three battery or connections .
Four USB port
Five motherboard .

Yeah, 2 days isn't right. It also shouldn't be discharging faster than charging, especially with the OEM charger.
I leave mine plugged into my PC (only 500mA max current) with the screen on (about medium brightness, mostly black screen, which is most power-friendly for OLED) using LectureNotes all day and it will neither charge nor discharge (technically, it's charging at the same rate it is discharging); the percentage doesn't move.
What does Ampere report?
Do you have another charger you could try? any 5V and at least 2A would work.
Also, ensure your cable isn't intermittently open (a break in the cable, temporarily disconnecting the charger).
If the cable and charger are good, then the battery would be the next likely culprit, followed by the charging circuit.
Finally, ensure heat isn't an issue (is it in a case? remove it).
Mine was messed up but I concluded it was the port and cable. I got a new cable and then replaced the charging port and viola. Charge time went from 8 hours back to the usual 3-4

Phone does not charge or boot after the battery was completely drained

A few months ago I got a new phone and put my OnePlus One aside. By the end of the day the phone had discharged completely and turned off. I tried plugging it to a charger the same day, but it wouldn't charge or boot. There are no vibrations, no charging LED indicator, nothing. I tried leaving it to charge for 6 hours, stop charging, and then reconnect the charger again but nothing. The battery doesn't even get hot after leaving it on the charger for 6 hours. It's like it doesn't even charge whatsoever. I swapped the battery about a year ago for a new OPO battery, and had no issues with it. This only happened after it completely discharged and refused to charge.
I used to have problems charging an empty battery with a low powered charger. Try using a 2000+ mA charger and a decent cable.
