Alright, so here is a fun issue to deal with. My notepro has always been a little slow to charge, but most of them are. However, its gotten very bad.
I have had issues with screen flicker and a little heat issues and some other small things off an on. So, fed up with it, a few days ago I rooted the tablet. It worked fine. Then I tried to install a new kernel and rom that was getting good reviews. However, when i did this, I couldnt get past the boot screen. Several reinstalls of stock and customer kernels later, my tablet started flashing and eventually died. When it was plugged in, it would show the battery icon with a circle in the middle but then die. Several tries to fix only seemed to solidify the tablet's fate.
However, yesterday I gave it another shot. I assumes the tablet had heated up and made the solder loose, so after a while it was solid again. It started charging, and after reinstalling stock rooted rom and stock kernel repeatedly, it was working again. I then installed the rom and kernel I was trying to before (I had to have a custome kernel to be able to control voltage for the screen flickering issue).
Now it is actually working. All functions are working, and oddly enough I am not seeing any screen flickering.
Only one real problem remains. Battery charging. The battery is charging so slowly that when the tablet is turned on, it doesnt charge at all, it creates a stalemate between charging and draining. It also drains pretty quick. The power drops about 5% in about 5-10 minutes of full screen brightness use (I was testing it this way to try and see if it would flicker again.
Its been charging for about an hour now, and only gone up 5%.
I have tried a couple cords and different bricks, but to no avail.
There are some thoughts, I am wondering if the tablet is only drawing power as if charging from usb, so only around 0.5a instead of 2.4a or so . I am also wondering if there is still a hardware issue.
I do not think it is the rom or the kernel, as this issue was happening as well after I got the tablet working again on stock but before I tried isntalling the rom/kernel again.
Any suggestions? I would be very appreciative.
I had simular problem with very slow charging, reboots and bluescreen. I opend my note to check battery plugg for broken soldering, but I found no problem with it. But to check turely i unplugged battery from main bord and replugged it again. After that I had no problem at all, now its charging normal, no reboots.. stil working perfect after averyday use for about 8 mounts......
If you are using usb cord not usb3 cord it will charge very little when using tablet . Mine will charge when off and below 25% to full in 7 or 8 hrs overnight.

Could be a bad charging port dock/flex cable. These are actually pretty easy to replace and can be found on Amazon. I had to replace one on mine. Try searching for a usb charging port dock flex cable for samsung galaxy note pro. That will cause the issues you are seeing. However the screen flickering sounds like a voltage issue caused by a cracked solder pin from the battery connection to the board. Which is very common on these and hard to see without an electronics magnafication glass. You could try taking the back off and pressing the battery connection firmly while plugging in your tablet and powering it one to see what happens. Either way sounds like a hardware issue.

Ok Guys, had the same problem with my 12.2 samsung tab pro, changed usb chargers, cables etc.
Found that the connector on the tablet itself (female) did not made good contack with the male usb.
So i simply , very careful, with a pair o pliers closed both tips on the usb conector, so the cable enters more tight. And voila, the usb amp meter i had showed a rate of charge from .33 amp , jumped to 1.73 witch is more than enough to charge and use tablet at the same time.
You need to do this at the end of the cable that plugs on the tablet, that is kind of double, maybe a e.0 usb or something like that. Make sure to close both tips. You want a tight connection

Is anyone else having an issue with charging? it worked fine for a week or more. now when i plug it in, to any outlet, it wont charge at all.. they are considering RMAing the entire unit, and im going to be torked off if i have to wait weeks to get another. argh.
just curious if anyone else is having charging issues.
thanks
My unit doesn't charge if the battery is above 90%. I see no problems there, what % is your battery at? That is expected behaviour to an extent to prevent overcharging of the battery.
Sent from my Transformer TF101 using XDA Premium App
Mine did that once and I just left it alone for awhile and it started to work again on its own.
i only noticed it because its asking me to connect to charger now.
so its at 11% right now.
Tech wanted me to trickle charge to see if i get anything out of it. Its not working.
Is there any lights on the adapter? i cant remember? but i think the unit may be bad.
SOOOOO pissed, now i have to wait weeks for a replacement to show up.
Has anyone else had a unit they have had to RMA??? is so, did they send a brand new one, sealed in box? if so, i have an extra here, ill just use it and sell the RMA one when it comes in.
thanks
EDIT: i had it trickle charging in the off position. just turned it back on. then plugged it in to wall. seems to be charging now.. WTH. wonder if its something with the dock?
Thanks
Hi
Nice to have found your thread on this - mine was doing the same thing after I had if docked. Connected it to my PC and synced and then put it back in the charger and everything is fine.
Weird.
Since you guys seem new to this forum, I suggest you read the stickies. The "Ultimate Transformer Information Thread" mentions some specific adapter issues you should be aware of.

TF101 not charging after run flat issue - SOLVED
Hello
I also had this problem. The tablet drained the docking station dry, and then neither device would charge from the adapter.
I solved the problem as follows:
1) Remove table from docking station.
2) Turn tablet off completely.
3) Plug tablet only into the charger, at this point the tablet turned on, and began charging.
4) Allow the tablet to charge completely!
5) Reconnect tablet to docking station, and plug docking station into charger.
Voila, all charged Hope it works for others who have this issue!
Mine also had charging problems. When I charged it, it never reached 100%. I took it to the Asus repair center, and they called me today and said they got it to reach 100%. Also, above 90% it reports the battery status as full.
I also to them about the battery drain problem, and gave them my tablet with the dual battery widget installed. Told them to charge both the tablet and keyboard to full, dock the tablet, power off, and wait until morning to see the results.
I'll find out what happens tomorrow when I go see them in the morning.
TF101 not charging today...
It happened already once some time ago, but leaving the power adapter disconnected from the wall plug for 10min solved the problem.
Now it's happening again... and previous workaround is not working.
Tablet is TF101, no docking keyboard, last version of ICS installed.
I've checked the various threads for suggestions: of course I tried the various reboot options; the only thing I'm missing is the refrigerator, but the power adapter is cold (tablet is not charging since 2d, and battery is still alive...).
I've not checked the cable, but have cleaned with air the connectors (just to avoid dust inside).
Any suggestion is welcome.
Thanks
I have had my charger stop working twice in the past 6 months. Both times I put the wall adapter in a zip-lock bag and placed in my freezer for 30 minutes. Upon removing I plugged the usb cable back into the adapter and bam, everything was working fine again. From what I remember, there is a temperature sensitive circuit breaker inside the adapter that sometimes gets stuck. Even if the charger is cold or has been left alone it takes the dramatic temperature of the freezer to unsieze it. Good Luck it worked for me, twice.
RESOLVED (Kinda)
Hello!
My VZW i535 just started giving me issues. I should preface this by saying that it is rooted and I do have a CM11 nightly flashed (will try to get specific version when I can, which may be awhile). I've had this installed for probably over a month now without problems. I also understand that charging issues are very common but nothing I could find is the same as my issue.
I noticed my phone was overheating (as it has frequently since purchased) with about 30% battery today, so I plugged it in after doing a reboot and all seemed well. About 15 minutes later I hear it beeping, giving the signal the battery is below 15%. It was actually at 5%, and the bottom of the device was extremely hot, as well as the end of the Samsung cable included with it, so I unplugged it and found that the metal part of the cable was mostly black and there was a strong electrical burning smell.
I tried two other USB cables, both in the Samsung AC adapter, and in the USB ports of several devices. With any cable in the adapter, it would say "charging" but would not actually charge, but with the computer USB ports it wouldn't say or do anything at all.
The battery is at 2% now and the device is powered off so that I can quickly do something if need be, but I can't do much. I ordered some replacement batteries with a charger, due for arrival by Friday 1/3, since I assume that the damage to the USB interface is permanent.
Is it likely that this was caused by the software? Or is the charger faulty? Any advice, in general? The warranty has expired, but I do have insurance on it if for some reason it would be better to just get a new device. I can't restore it to stock until I get replacement batteries; is that what you recommend?
Thanks so much!
Sounds like a hardware i ssue. Look inside ur usb port on the device to make sure it did not get burn. Wen ur battery comes in put it on and try to charge it with new cable. If it doesn't charge then it will ur USB port. I know some 4.4 roms give wonky bat stats but it shouldn't burn out ur cable or usb port at least i think it shouldn't. If u believe is a software issues flash a different version of the rom a previous build or a whole different rom. But with 2% battery i don't think u would be able to. Good luck
After playing around with it a bit, the USB interface on my phone definitely appears to have taken damage from the heat. It only charges when powered off, must be completely still, and charges relatively slowly.
What I would recommend for people with a similar problem is to do as I have done and purchase extra batteries with an external battery charger like the set I got for around $17 on Amazon.
My only guess for what caused this is that something faulted in the cable or AC adapter and caused a severe overheat issue. If anyone has anything else to say about that, please let me know so I have a better idea of what happened. I will mark as resolved soon.
Hello guys, i am hoping that you can help me because i don't know where else to turn. I purchased a Verizon note pro 12.2. I was using it and on for about two weeks until i got my surface 3. Two days ago i went to use it and it wouldnt turn on. I assumed it was the battery so i put it on the original charger for about an hour and attempted to turn it on. It booted to the Verizon logo then flickered off. I put it back on the charger overnight thinking that would fix the problem. When i attempted to turn it back on it loaded to the Samsung splash screen and then turned off again. When i plugged in the charger once again the grey battery icon came up saying the battery was 100%. Even with the battery saying it was 100% it still wont turn past the splash screen. This only happens when it connect to the charger. it doesn't do anything at all if it is not plugged in. I have taken the battery out and reconnected it... still nothing. Looking at other post i assumed it was a software issue so i tried to sideload a stock version (Cant use odin because the tablet cant even boot into odin mode) of P905VVRUANK1 which is what the tablet was running. I got the error footer is wrong security authentication failure. I dont know what to do. Please help!!
correction i did not sideload (wrong terminology) i tried to flash through recovery mode.

Probably you have a loose or cracked battery connector. Try this, power on while pressing hard on the back near the center ( location of battery connector ). If it can boot this way, you need to re solder the battery connector.

I have tried this but still nothing. I also switched out the battery with another note pro and that tablet powered on with no power. when i tried to use that battery in mine i still got the same result.

I have seen this problem in many Tab Pro or Note Pro: it cannot turn on even with full battery. When battery connector's pins are open or cracked, your tablet won't be able to turn on. There are too many unknowns such as USB charging port, battery connector, or battery. You need this tool to find out where is the problem:
http://www.ebay.com/sch/i.html?_fro....TRS1&_nkw=usb+voltage+current+meter&_sacat=0
When charging, current should be 1.7 Amps.
It sounds silly but I see many users cannot figure out the problem which simply comes from bad USB cable or charger or USB charging port. This tool will eliminate guessing.
Since checking battery connector requires experiences to know the solder joints are good or bad. My recommendation for your problem: Re solder the battery connector if everything else: USB cable, charger, USB port, battery are in good working condition.
Use another battery you won't see the difference if battery connector on main board is cracked or loose.
Cracked battery connector is very common in this tablet but most average users won't see it or don't understand why it's the source of problem.

I do not believe that is the issue. the charger i used after the fact was a samsungng 5.3v charger thats belongs to the other note pro. im assuming if it was a issue with the amp that the other note pro would have the same issue... could it have something to do with the bootloader maybe.... or maybe theres a file i could flash that im just not aware of...

Beut was right all along...
Hi, I am a novice in phone repairs though I have successfuly replaced the screen and charging ports on a samsung s6 and note 4.
I am requiring some expert advice on this problem, I was given an XZ from my friend with a cracked screen and charging problem, the charging port became temperamental and failing (at least I think it was that) and eventually wouldn't charge at all. The charging port was handled a bit harshly toward the end, for example the charging cable lifted up and down to try to get a charging response.
Anyway I ordered a screen/digitizer and charging port flex for it, and fitted them, following a guide. Before this, the phone had around 2% charge. After the repair, I switched it back on and conncted the charger, the screen was fine, however there was no response from the charger. The phone then ran flat and eventually ran flat enough to not be able to show the "low charge" symbol when the phone is off. Then after plugging and unplugging the cable (via USB in the pc) it would charge for what seemed a second then stop, the red charging notification light was lighting up. The same happened with a wall charger. I then stripped it back down and back together again. This time there was no response if I remember right, then I connected it to the wall charger and left it for 3 hours or so. I went back to it and it had charged up to 15%.
Now i'm at the point where the phone is working, it's on 90% now, but it charges very slowly, around 60-350 mA per hour on Ampere app. So a full charge is around 12+ hours. This is in the wall socket with a fast charger. Additionally, it takes 10 seconds for the phone to recognise the charger after is is plugged in and that is consistent each time I plug it in. The phone now isn't recognised by my PC via USB, and also won't charge that way also, it just doesn't do anything if I plug it in there. Other than that, the phone works and it holds its charge well.
Any ideas? Thank you.

pick up an original sony charging cable - no idea why it makes such a difference, but.........
Hi, thanks for the reply, I bought a sony charger but it's still the same, drawing about 50-300 milliamps from wall charger, not recognised by PC and takes 10 secs exactly for the phone to recognise it's being charged. It's just odd how it stopped charging before the "fix", now the new flex lets it charge slowly. Can a battery problem cause this? It still holds its charge well. Maybe this problem is recognisable by some phone repair experts around here? any ideas?
Thanks
Noticed the phone only draws charge from a 3amp charger, anything less isn't recognized. And the power drawn from a 3amp can be 30-1000ma but averages around 300 ma. Can anybody point me to a hardware forum maybe? I can't find any, i guess it need taking to a phone expert but it's gonna end up costing more than its worth with the stuff i have done already.
Aukey Quickcharge 3.0 is working fine. It is cheap too.
I have just purchased a aukey charger, but my XZ seems to be taking longer to charge than the UH20 charger that came with my XZ. Any suggestions guys?

Have you tried cleaning/replacing the charging port itself? As i see, you replaced only the flex cable.
There's probably extremely weak contact somewhere in the charging hardware i think, because you need 3.0 A charger to get any kind of charging response. Weaker current probably gets lost at that 'weak contact'.
Buying new chargers won't fix that if you ask me
I have exactly same problem with you
I am about to buy a new charger, yet I saw your post
At first I thought it was the cable. Then my cable work normal with other phone. So does my charger, it connect perfectly with other phone (xperia xz premium and xiaomi mi5)
It seems that our phoneis the only one who can'y charge normally.
I am quite depressed, also looking for solution. Mind if you share if you have succedeed? Thanks before

Try plug in and plug out. My phone sometimes charge a normaxl. But need a lot of effort
Solved
Use the the detect usb in the notification keys before connecting the charger,, this will solve the fast recharging issues
Did you solved problem? I have same issue. Changed battery, usb-flex, no luck
Hi,
I have bought an used XZ.
The owner sold me this phone because he need new battery. I have replaced the old one after a week of test. The old battery works only for 6/10h and drain totally during night even if the phone is turned off. The new one have the same problem. I try to solve with an other battery, and nothing same problem. 12h of standby, after is totally drained. The strange thing is that I have the same battery life even when the phone is turned off, but not only this. If the phone is in 0% he charge without problem. If we have any % of battery I need to connect and disconnect the charger from a wall plug many and many times before he start charging. Phone give me the charge icon for a second and after nothing until I disconnect the charger from a wall plug(I have tested different charger and cable). During my investigation I have found that this phone results every time a little bit hot even if turned off. I have try to disconnect all is possibile, but the heat is from CPU! Now I know that this is the cause of fast discharging in all conditions.
Now I need to know if anyone with a "normal" unit feel the phone heat while turned off and while is on wich temperature have. Mine is every time on 34/35° in standby. Let me know,
thanks
i have same problem . sony xperia xz and sony corp is very very Rubbish
Hi Guys,
I found a way to charge my Xperia XZ with the same loop problem.
Try to push upper volume pad together with power button and plug in the charging cable.
Hold the buttons for 3-5 minutes - you will feel vibrating signals like 3 short and 1 long.
so hold it and then simply leave it for a several minutes and it should start to accept the charge.
Alex Kutikhin
Yes - I had this problem...fixed it by holding in POWER UP and OFF button for 120 seconds.
Do not let go...you will feel vibration (1 short, 3 short). Keep holding for 120 seconds.
Device should now be powered down. Plug in charger cable and leave device off until 100% charged.
Still no fix for the original post’s problem? Having the exact issue with my xzs right now.

Old Thread, I know, but I encountered this issue today on an Sony X compact - F5321. Fixed it and want to report back for the next guy.
Same symptoms, noticed first a slow charge, phone was drawing low current and only responding to cable after 10 seconds of plugging in. I than checked for data connection, couldn’t get any. Opened it changed the USB port - BINGO - that fixed the issue, everything working nice.
TLTR: no Solution in Software, it’s a faulty USB-port. change it.
Have a nice day.
I rooted my tab and installed Android 6. After I took those steps, I noticed that it wouldn't charge unless it was powered off even though the charging icon indicated that it was charging when it was powered on. Then I stumbled on something that said that if you just barely connected the charging wire to the charger that that would help solve the problem. See http://forums.androidcentral.com/sa...-galaxy-tab-2-wont-charge-when-powered-2.html For some reason, this works and I don't know why. Does anyone have any ideas? (Again, when it was totally powered off, it charged fine.

Consider replacing your charging wire and brick. That happened to me way back and I'm glad i don't have to adjust the wire to get it working.
Lightracer,
Thanks for your response. However, my Tab 2 is my backup Tablet, and the charging cord is good enough for me. I am curious as to why barely inserting the wire into the charger causes the Tab 2 to charge correctly. Simply makes no sense, unless a good number of charging cords have the same defects. Also, what is weird to me is that my Tab 2 charges correctly when it is powered off.

Well the answer to this weird issue might seem to be from a software related one. since the same cable charges the tab while it's off. Right?
but in my experience from all the experiments I have done, this issue is solved only by changing the cable or the whole charger or consider replacing the battery(Root cause of your issue).
a battery near it's end would have all sort of weird behaviour.
it will deplete if using while charging, would go from 100 to 5 percent if you restart, then start going up again if left untouched without charging. so there you are!
hope this would make things clear to you now.
