Hello.
Yesterday I upgraded from KatKiss #018 to #019. Up to now #018 had worked perfectly, but today with #019 I noticed that when plugging in my charger (I don't have the dock), I didn't get the little 'flash' sign on the battery notification; going into the settings to look at battery usage, I noticed that i said 'Battery not charging' even though I had left the charger plugged in.
I unplugged the charger, turned off the tablet, and replugged the charger, and the tablet turned on, which it does when plugging in the charger and being off.
Has anybody had this problem? Is it really charging but not notifying it? If not, what can I do besides reflashing?
Thanks!
me too

me too, i just flash it usually,,, battery at 100% wipe cache system etc, when my tf reach 0% it wont charge, but when i charge in off mode ( shutdown TF ) it charge but so long, 8 hour only charge 20% need help to resolve this issue,,,
I have the same issue, battery will not charge. and it seem that it will not get supported here, no answer from the dev, please dev look it up
I am fine with kitkat 19. You guys above may give a try to change a data cable to charge your tablet.
not sure

No problems for me and most people I guess otherwise they would stay away from the rom if it was not charging
Try to power off completely your tablet, then cold boot.
Try to change cable, try to test with another charger.
If that doesn't help do a full wipe and a clean install and test again before reinstalling anything else on your tablet.
if that still doesn't help, follow the procedure to report an issue in my signature, I'm not psychic.
Hello.
I have a problem related to the battery as well. Ever since I flashed to #19, my tablet and dock battery seem to run dry very quickly in sleep mode. I have come home from work to occasionally find the tablet unable to boot (it had a dock charge of no greater than 75% and a tablet charge of 100%) and when I plug the charger into the dock and then boot it, I find both batteries have next to no charge.
This is only on timduru's KK#19. I never saw this problem on #18 and below, or any of the previous 'droid versions (4.3.1_029 or 4.2.2_226).
I am currently letting the tablet's battery run to empty and then I will be charging the dock and tablet separately, but this is the first time I've ever encountered this problem.
okay

Did you try another ROM? I'm on #20 and I think I have (mentionable) more battery life. Not charging issues. Guess the fresh installment / wipe helped or an energy eater didn't survive the reinstall. Also I could observe two things (which I don't know of if they are related): Sometimes when the tab was docked it didn't charge. Second the the tab hat a battery problem. When docked and in sleep -> Dock empty next morning. I controlled this with Juice defender but weren't able to locate the problem in an app. This is now gone.
From my experience: I bought 2 power cable for the TF101 (only cable). One works as USB cable with no loading feature (not on USB 3.0 nor on the wallcharger). The other one works as USB connection cable and as wall charger. I can extend the original cable with USB to USB cable to transfer data and charge. I can't get any of that both two (CHEAP) cables to load extended or trasfer data. The two cables I bought at ebay were diffrent vendors. One for ~2,50€ the other for ~4€. If I remember right the original cable where much much more. What I want to say: There are huge diffrences in USB cables. Dunno. It would be a strange accident that the charger or cable broke when / while you intalled a ROM. Could it be that the "intelligent" battery stats are broken somehow? So they think the battery is full and therefor not charge? Or would the icon / indicator then show 100%? Does the icon get its information from the same source (or directly from) as the android battery management?
(ps: 12 hours for 35%=! ROFL!?? What charger is that?)

if it takes that much time even when it's off, it means that it's only charging at 5V.
Also at 5V it won't charge unless the screen is off if I remember well.
There's a special pin/connection made in the cable for the charger to detect that it's a Transformer plugged that will make it charge at 12+V
There's most likely a pin/ contact broken either in your cable / charger /tab, that prevents it to charge at high voltage.

So you say you go with option #3 then because u already did option 2, right? Quote Tim on option 2: "Try to change cable, try to test with another charger.".
So you have 2 x THIS and 2 x THIS? Because that would mean, what Tim suggested I guess. As far as I know this is the only way ASUS shipps the original TF101.
I'm asking because most people that I know would buy another noname charger or even just a noname cable instead of horribly expensive original pieces. If you really got the 2 x 2 pieces shown above,
then I'd guess wether your tablet is broken or the software on it is broken. But again: Did the charging problem REALLY firstly appeared when intalled the ROM? Or did you install the ROM because of the
fault? Or don't you exactly know.
To point out again: It would be a strange coincidence, that both cables AND adapters would stop working exacly at the same time when u installed #19. If you use 2 different cables at the same adapter: Then it's possible that the adapter is broken and only gives the USB (5V) loading speed. If you use 2 adapters and 2 cables and tryed all combinations: The most likely something with the tab isn't cool. The software or the hardware...

Precisely what I meant.

I have loaded #29, and I started seeing this issue immediately. It was fine before that. After loading the ROM, it would only charge when TF is dead. I have the original charger and cable that came with it which was working fine before the upgrade. So, I don't suspect either of them.

I was going with #29 and #30. Havent seen or heard about any loading issues but that was related to loading the tab on an USB port ... What actually is an bad idea even on USB3.0.
Gesendet von meinem Transformer TF101 mit Tapatalk
So I bought a cheap cable from eBay that converts microusb to the proprietary Galaxy connector on this device. Tried to charge the device but it entered a bootloop. Unplugged the cable and tried charging with the stock cable and left it overnight. Woke up and the device was completely dead.
Wouldn't boot at all.
Tore it open, unplugged the battery and plugged it back in. It booted! BUT the battery was critical and it shut off immediately. Tried charging again, no dice.
So I unplugged the battery and applied 4v to get some charge into it. Got the battery up to about 3.6V, booted again and it showed 3%. So in the time I had with the device turned on I tried both cables again but neither would charge the device. I used a multimeter to test the stock cable and it was all good, I even did a beep test between the 4 USB pins in the stock cable and the places they're wired up to inside the note and everything was fine so it's most likely not the cable.
Anyway the 3% is long gone now and I can't boot or charge. The device and battery are fine and definitely working, it just won't charge through USB no matter what. I've tried different power points, different adapters including stock and normal usb ports.
I've also cleaned both the plug and the jack with a toothbrush.
Could it be that the internal charging circuitry got fried when I tried the dodgy cable? If so, is there any way to fix/bypass this?
I'm at a complete loss so any help would be greatly appreciated.
Regards,
Nas.
I would not recommend to charge battery directly outside the device or even remove the battery at all.
First you gotta make sure your cables are capable of charge other galaxy devices if a friend has Tab 7 or Tab 10.1 or other note 10.1 or another try your cables to see if they really work.
Because it may just be your cable, remember batteries have their own circuits boards of sort and batteries are sometimes picky on how they are charge especially OEM batteries that are not suppose to ever be out of the device unless are change for a new one in a repair.
So first of all cable check it a must, again is not as simple as check if all the pins works as this is not a simple USB (Universal Serial Bus) port is a proprietary port and cable, check the port in the tablet too.
As well it may be just a defective battery or worst case even a board problem.
Unfortunately I have no other device to test it with. I might just buy another cable and see how I go.
I know about the circuits on the battery, but I always thought they were just there as a safety measure due to the potentially volatile nature of Li-Ion when it drops below a certain voltage. I'll probably take your advice and stay away from charging it externally, I only did it once to see if the tab died or it was just a dead battery. The voltage never dropped low enough to trigger the circuit to 'kill' it, evidenced by the fact that I could get it back up to 3% just applying a constant voltage.
I'm guessing you've hit it on the head with the last sentence, might be a board problem which would be quite sad. Silly reason for a great device to die.
Thanks a lot for the reply, I'll update this thread once I try an alternative cable for future reference.
Ok, So to update:
I've bought and tested 3 separate cables, all provide 4.99V inside the device, but none of this makes it to the battery so I'm fairly certain it's the charging IC that's dead.
I bought a new battery that was charged to 40% so I was able to flash the device to see if it was maybe the custom kernel messing something up. Flashed to stock via Odin, still not charging.
From what I've read, I need a cell balancing circuit (since the battery is 2-cell Li-Ion) and a charging IC. I've found a suitable IC for fairly cheap, but I'm not sure if the balancing circuit is necessary. The battery already has one of these inside, but I'm not sure if this is just for Voltage/Current protection or if it also balances.

Hi all,
My friend's OPO does not charge when connected to the USB port of a computer. It is stock, unrooted, KK 4.4.2.
It charges fine when he charges via the wall charger. My OPO charges fine out of the box, with USB on the same laptop and port.
He does not want to factory reset and I am at a loss here. Please advise what I need to check here.
Thanks!

He can buy a universal adapter for the charger. They're pretty cheap.
It's because the laptop isn't putting out enough current. It must be at least 2a to charge properly.

The issue here is that my OPO charges through the same USB port and with the same cable. That's what has me baffled.
Well consider me baffled too.

Anybody has any idea about this issue?
The front panel of my pc case has usb ports that has trouble recognizing or charging any phone. When I plug it in, the phone will show it charging but the battery continues to drain or I can't access the sdcard. Not sure what causes this, but when I plug my phone into the usb ports in the back that are connected directly to the motherboard, then there is no problem.

Uh, I'd say factory reset or don't worry about it.
Not sure what you expect to hear. But that's probably the first plan of action. Especially since yours works fine.
Opo has higher power requirements. You may need a cable with a 24AWG or better rating (lower allows more current).
Does it work with the stock cable?

My OPO works with any cable, though time to charge is the best on stock cable. But my friend's OPO doesn't charge at all. Even on stock cable.
Unable to make sense of it at all. I may sound like a simpleton, but maybe there is some checkbox I ticked somewhere which is preventing this? UGH!

The phone will work with any cable. Worst-case the cable's resistance and diameter will reduce the maximum charging current significantly but it always will charge the phone.
It's because the laptop isn't putting out enough current. It must be at least 2a to charge properly.

No USB port has that much current except maybe for highly specialized ones. USB2 is rated on 0.5Amp, USB3 on 0.9
Of course the phone will take significantly longer to charge or may even discharge when used while plugged in.
I can say "me too". My one also didn't charge from powered off PC while Nexus 5 plugged in the same PC with same cable charges fine.
When PC is powered on, One charges intermittently. I.e. I plug it in, it charges for some time and then stops. "OS monitor" shows "discharging [USB power]" state.
Any thoughts?

Cannot charge OnePlusOne via USB
I have the same problem.
The problem seems to have started AFTER upgrading O/S to Cyanogen 12.0.
Cannot charge via USB either from my note PC or Mobile BatteryPak (1.7a).
Above comment that 2a power is required is surprising, as I thought 1a is standard. Maybe there is some Cyanogen bug here?
I found in some Forum to make of SETTINGS - STORAGE - USB COMPUTER CONNECTION, but I do have this setting, and still cannot charge the computer.

It will charge very slowly but will charge faster if the device is off. If you're using it while it's charging it's like filling a bucket up with water that's got a hole in the bottom. It fills up. But slower than it would if there was no hole.
As for the battery pack I have a 2.0a EE Battery pack and it works fine so it might be related to the analogy above.
Sorry to bring up an old topic, But its still hanging and non has really come up with solution. So i thought let's bring some light to it.
My dad has encountered the same issue the other day, I'm basically not much PRO into fixing things like this but by turning on/off USB debugging while connected to PC and also turning on/off Developer options does makes it charging through PC again.
Previously it was charging by PC, but dad has messed up something internally and asked me for help, so this lil so called tricked work for me. I hope this will help others to.
I have looked around on this topic before posting, but nothing applies to what im experiencing
Up until this morning, I haven't had a single issue with my USB port or charging in general.
I clean flashed Purity KitKat, flashed compatible Uber kernel and installed my apps as one usually do, and let the phone charge for a while. A few hours later, I realized my battery was at 0%. I started panicking, looking for a USB replacement part, which I found for about $12 on Amazon. I decided I would download GSAM battery monitor to see if there was an issue with my charging cable.
What I saw was the mA flow was acting erratic, sometimes shooting from -700ma (yes, that's negative 700) all the way up to 1800mA. Even by just rotating the screen, it would drop instantly. . The phone charges, but a little at a time. I disabled KSM and fast charge which seemed to have a positive effect.
I'm not sure what caused this, or how to fix it, but I've attached a couple pictures to give you an idea of what I'm seeing. If it is in fact the USB port, would using a Qi charger be a good option or should I just go ahead and dismantle the phone and replace the USB port?
Note: windows still recognizes the phone and I can send files from the computer, and the charging bolt is showing.
Have you replaced the cable? Far more common for the cable to crap out then the port. Cheap or broken cables will appear to work, computer will detect phone and even display a charging indicator but it won't actually charge. Had happened to me in the past.

Try flashing the stock rom to rule that variable out. If you want to be sure that is the usb port you could try with a wireless charger as it could also be the battery, you can find a new one at the same price range of the port.
It does seems a lot like what happened when both the stock charger and the cable were damaged. I tried to charge the phone and when disconnected it had less charge.
So a problem reared its ugly head a few days ago...
I tried to connect my phone to my PC to transfer files, but the PC wouldn't detect the phone. It wasn't charging when connected to the computer either. I tried different USB cables and different computers - same problem. If I turn the phone off it suddenly charges, which tells me the USB port on the phone is working. I also tried different chargers too.
My device is rooted, so I thought it may be the ROM I'm running. I wiped the device and flashed another ROM, but still the same problem persists.
It seems like a firmware issue to me as it charges when the phone is switched off. I hardly ever use the USB port on my S6 as I usually charge wireless. I tried cleaning any lint and dust out the port too using compressed air and a toothpick - it didn't help.
Does anyone have any idea what the fault may be?
Are You using USB 3.0 port? Cause I had the same problem. Usb 3.0 never recognised my device. Now after I flashed 6.0.1 the problem is gone.

Tried on USB 3.0, USB 2.0 and a power brick, Mac and PC - all the same result.
Similar Problem
I have similar problem too. My phone is Samsung Galaxy Alpha. Yesterday, I charge my phone using Pineng Powerbank and then i notice that it show the lightning symbol but the battery is not charging but decrease and my phone become too hot. Since I don't bring the charger, I'd try to connect with different USB cable to PC and the problem is still the same. Then I remove the battery for few minute until the phone is cooling down. After switch on the phone again, my phone quickly heating up but the battery is normal. I'd buy new battery for replacement but the problem still occur. My phone also is not charging when in safe mode and only charging when it is turn off. Then I made a factory reset and it's work. Both of my battery is working too. What is actually happening? Does the powerbank is the culprit or virus? Thank you.
