Slow charging

Sometimes (no pattern) the note charges very very slowly: in 4 hours this morning, for example, has increased of only 15%.
You can tell cos the charger is not hot.
Is it a charger/cable/connector problem?

Do you see a little red "X" over the battery when this happens? i believe unless you use one of the Samsung chargers it won't charge at full speed but will still trickle charge slowly. I've also found that even with the Samsung charger when I used a really long USB cord I wasn't getting full speed charging, so a long or bad cord can be an issue.

No red X, original cable and charger... To solve I have to unplug e replug couple of times

Same here
When I connect the Note 10.1 to my Computer or last time I tried to connect to car charger it gives a red cross. Why does this keep happening ??

My note 10.1 just started charging slowly noticeably.
I used an app called Galaxy Charging Current, and sure enough, the status shows that it is charging at 1amp, instead of the nominal 2amps.
This is on the original charger and cable.
I recommend everyone to check out the app called Galaxy Charging Current.

The red X is difefrent: you cannot charge the note 10.1 with a usb cable or in car with a 1 Amp adaptor, it needs 2

Opinion
My GT-N8000 from original ICS 4.0.4 until now using XXCMI2 DBT Deodexed sometimes too long for charging ( charge always at power off mode ). sometimes 5-6 hours and it still not full 100%. It'll be full 100% if unplug and replug again and wait at least 1 or 2 hours. after long time experiment, My conclusion when charge at power off from 35% or below, It will be 5-6 hours charge and not full but charge at 60% power off mode charge it will be full 100% charged just 2-3 hours. that's very strange. at power on never got this problem, always 100% full.
All accessories, charger and cable data were original.
Any Opinion???
Thanks

could be the ROM you are using. Did this happen when you were stock? I know on my HTC one there were a few roms that I would have to plug the USB in three of four times just to get it to work correctly. Then I changed roms and BOOM works perfect again.

@Tiltmfc
For Me that happen on stock ROM too, coz when I purchase this N8000 at special price on 1st day launch in Indonesia, I must wait until root feature available at least 2-3 month and I always charge at OFF condition and almost rare at ON mode. at official ICS at OFF always like this, real real long to be fully charged when start charge at 30% and Don't know when reach 100% if I don't unplug the charger cable at least once.

I had the same problem previously. Solved by getting a new charger (whole set including the cable)! One hour charging = >15% increase

Cool
Wow Cool, maybe charger problem. For Now I've never charge my N8000 below 60% at OFF Mode. always taking 3 hours charging time to 100%.
Thanks for sharing.

Yep I'd agree that it sounds like your charger or wire is on its way out. I had a similar issue with my S3, changed charger - problem fixed

Samsung 10.1 Note N8000 charging slow
I have one from early 2013. The issue is that during the charging process, sediments get deposited both on the plug and the socket. This over a period of time reduces the contact between male and female parts contributing to slow charging.
In a post, some one mentioned that his friends charger worked on his tablet and his charger did the job for his friend. Some one was able to fix the issue with a new charger. The fact is, any change that reduces the sedimentary issue thus enhancing contact will work better.
I took an obsolete tooth brush cleaned the plug and then held the phone's socket down while cleaning that as well. Vila, my charging speed has improved.
Samsung had a proprietary cable for 2013 and later they replaced it with micro USB in 2014. The sediment issue is not as pronounced as in other mobiles which use different cable type. In N8000, the current in DC o/p is also high at 2A which may be causing this problem.

Samsung tablet SM-T805 charging issues...

For the past 3 months my tablet has been struggling to charge.
I would plug it in, it would show the charging icon on the battery, but it won't charge. Sometimes it will INCREDIBLY slowly. Other times (most of the time) the charging percentage will decrease while its plugged into a charged.
I have tried:
1.Soft reset
2.Hard reset
3.Removing micro sd card
4.Different (original) lead
5.Different (original charger (3 in total)
6.Opening it up and disconnecting the battery terminal for 5 mins
7.Holding down power while battery disconnected
8.Connecting the charger FIRST before connecting the other end to the mains.
Im getting nowhere. Currently its on 1% and just wont charge.
To me it could be the charging port or the battery. How do i determine (without spending heaps on a battery) what to replace first?. Is there anyone else with this problem?.
Thanks

Just now i plugged it in charge. The tablet is off as its on 0%. It took 30 mins to get to 4%, then it went back down to 0% instantly.
But like i say, when it DOES have a charge, the charge is usually decreasing as the charger is plugged in, till it reaches 0%!. Only sometimes very randomly and very rarely will it actually charge properly, and when it does it operates perfectly with it OFF the charger. So it doesn't drain dramatically off the charger.
Right now im struggling to even get a charge out of it now.
Can someone help? charging port or battery fault??

I'd say it's the battery.

Its on 30% now, creeping up slowly. So strange.
Have you seen any other cases the same to say it is the battery?

When a device charges strangely fast or agonizingly slow, it's typically the battery, also, randomly discharging fast is also a sign.
You could always have a repair take a look with a voltmeter, testing the battery and the USB port/charging components. Or you could do it yourself.
Sometimes it's just the solder working loose on some of the pins from your USB port, you can do a reflow on those solder points.

malfunction of the battery

Hello everyone! this morning something really unexpected happened to me. my Honor 8, which I usually leave on at night, woke up with me about 20% of residual charge. after a few minutes of use, the latter has passed (20 ---> 2) in an instantaneous way, forcing me to turn off the phone. then I connected the charger but charging still started by 20%. Unsatisfied, I turned on the phone again and again I went from 19 to> 1% instantly. now I'm charging with the charger but I have no idea what might have happened. I think the life of the battery is good, since alternatives are generally fast charging with slow charge from the USB port of the PC. what could have happened?

Do you use the stock charger that comes in the box? Other chargers don't work well with Honor 8

Yes, only stock charger! Sometimes USB port of the PC (like 1 charge every 10 from original charger)

Check the charger for any possible damage. There may also be something with the phone itself.

SuperCharge problem: defective charger or battery?

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

OnePlus 6 Warp Charge Problem

Hey,
Recently I've got a OnePlus 6 but it came without any charger. So I have bought a 30W warp charger which was taken from the OnePlus 7 Pro box. It charges and works fine till the battery is charged to 65%. After 65% it stops charging and I have to switch to some other regular charger or charge it via USB port from my laptop. to charge the battery from 65% to 100%.
I have cleaned the connection on phone, I've tried another cable but the result is always the same. Battery optimization is turned off.
I need your help: What can cause this problem and how I can fix it? I don't have a chance to test it with another warp charger, since I don't have access to other ones. and it is very uncomfortable for me to charge with two chargers -_- Please help...
