Hello!
In advance: I've a "Cubot X9" Smartphone - but the error exists for many smartphones of nearly all brands when you Google. That is why I ask here, I hope, this is correct. Maybe someone has a solution...
As I said, I've a Cubot X9 Smartphone. Since the day before yesterday I have the problem, that it is not possible to charge the phone when it is powerd on. When I power the phone off and plug the charger in, the phone starts charging and the charging LED and Symbol on the Screen lights up.
When I switch it on, the charging immetiatly stops.
I verified the phenomenon with a USB amere meter: When the phone is switched off an I plug the charger in, the current goes up and the phone is really charging. When the phone is switched on and I plug the charger in, the current stays at 0.000A and the phone is really not charging!
I also tried charging in TWRP - there is no charging either.
Another problem is, that the phone is not recognised by the computer. No error message, nothing. It seems, as if the USB port is switched off completly!
I found out, that there are many many phone with this Problem (SGS3, Google Nexus, HTC, ...) but there is never a solution. The problem is always the same: Only charging when switched off and no Connection to the PC.
Do you have an idea?
I already tried to:
- clean the USB-Port from dust
- changing the cable and the charger - I tried about 10 different ones
- disconnecting the battery (I opened the phone for that)
- clean and whiped everything (Data, Cache, System, SD) - although in TWRP and in Android
- flashing a new OS (Cynogen 13 instead of Android 4.4.4 stock)
The Problem still exist! I already thought about changing the battery to a new one. But the phone still last longer than one day, there is no Change in running time...
Is it possible, that the USB-port is damaged? Maybe the Pins for + and - are ok and the phone is charging when powered off. And when it is powered on, the data Pins are also "checked" for a connection - and because they are defective, the connection is not recognised and the phone does not start to charge?
I really like the phone and don't want to buy a new one, because the cameras are masked for security reasons and it is really difficult to get a new one sealed...
Thanks a lot for your help!

hello...i hope that someone can help me....when i try to turn off the device,it shut down and after few seconds reboot?why?
also simetime the phone don't turn on and on screen i see a green battery with a thermo....someon can help me?
Did you find the answer to this? i am sending my SGS2 back for replacement. i have the same errors plus the following.
Phone selects speaker rather than earpiece as default for incoming/outgoing calls
Phone on ocasions randomly starts Kies and Voice commands even if there is no physical contact with the phone
sometimes the phone defaults back to a launcher i have never seen before (it is not touchwiz) and i have no idea how to launch it without it doing it automatically.
The faults you mentioned can be bypassed with a battery pull but they are annoying, I didn't have these problems until i upgraded my firmware through Kies to KE7.
I have an O2 branded device.

Randomly my phone will:
-go into driving mode
-answer calls in speaker phone mode
-start alarm clock
-think its charging when the cable is not plugged in
-Reboot it self/turn it self on when its off
-wont connect to computer or charge even when cable is plugged in.
I need to send it in for repairs what should i flash? there is no bell branded firmwares or roms.

Exactly the same to me
How do you flash congnition? just over the stock rom with odin?
did you flash modem?
Absolutely same here, since coming from CM7 to VillainRom.
Never had that before.
I´m waiting and watching it and your results!
Thanks for this thread.
That's why I don't root the phone..it works fine.

This has nothing to do with root access.
I cannot believe that any problem related just because you have access to your system.
Back to topic, flashed back to cm but problem persists.
It's getting really bad near to flashing stock and bring it back to change device if someone knows what it is could be helpful.
I also have this problem. I think it has something to do with the usb port.
Because sometimes it just scans for media, or it thinks it is charging. Really weird! Then i just put in the charger and it stops for a while. Turning off will just reboot the device. And removing battery and plugging it back it also just reboots the phone.
I hope it is not hardware related...
I was looking for help for a problem I have but this seems to cover most of the problems I'm having.
Mine has recently started going into a strange mode after shutting it down. I get the battery charging symbol alternating with the "battery overheating" symbol.
The only way to stop it is to remove the battery for at least a couple of hours (if you put it straight back in it automaticly starts up and goes back to flashing the battery warnings) or pressing Power, Vol+ and Home and choosing Reboot.
I have also noticed its very slow to respond to plugging the charger in or out. It doesn't always wake-up and bleep when the charger is put in and it stays showing its charging for some time after the charger has been removed.
I was told that the charger should be removed as soon as charging is compleated but surely overnight is the only time we have available to charge these phones!
Depending on the custom rom or kernel you are using, it might not support off mode charging.
To avoid having a "problem" with charging the phone in off mode, some developers decided to make the phone boot up when the phone is been charged when the phone is off.
Going back to an official stock ROM fixes this problem.

As for Cyanogen, since built 23, you can charge the phone when it is in the "off" state. Please wipe out your userdata partition before flashing. Do not restore from a previous backup.
I fixed my reboot problem (rebooting instead of turning off) by letting the battery drain all the way so it couldn't boot anymore. Tried turning it on to see if it really doesn't go on anymore. After that I plugged in the charger and I got the charging-symbol and it did not turn on so I kept it charging overnight while turned off and in the morning it was finished and turned it on.
I also cleaned the usb-port on the phone with a toothpick. It had alot of dust stuck in it which I couldn't see. After that no more problems...for now. They haven't returned for 2 days now.

What kernel and rom are you using? I have not seen the battery overheating symbol on the sgs2.
No, there is no need to remove the phone from charger, when the phone gets to what is considered full, the battery will stop charging by itself.
Are you using the original samsung charger that came with the phone, or are you using a after market charger? Most of these USB chargers do not send a signal on the data lines. When using these chargers, the phone becomes laggy and unresponsive, there is also a delay to register anything on the touch screen. Stay away from these chargers.
For lithium batteries just charge it whenever you feel like it. Lithium batteries have a few thousand deep charge cycles, meaning if you use up all the power, then charge it,you use 1 deep charge cycle. However, if you use the micro cycles for charging, you can charge the batteries a few million times. Leaving the battery on empty for too long will damage the lithium battery.
Can any one confirm if this is a hardware or software issue as i now have the problem when i try and switch the phone off it will just reboot?
The Same issue occurs in my sgs2
hi everybody,
i just got my sgs2 ten days ago
everything seems good at first
then i realized screen standby lock lag problem, there exist a lag between 1 second to 2.5 seconds.
i ignore that due to it cannot be named as a problem, it seems like a bad characteristic
then yesterday , i have faced with another problem
after i have docked the phone to the original vehicle dock kit,
phone cannot be closed via power button , i hold it 1.5 seconds then chose turn off among list, phone looks like to be turned off then after a little while it just vibrates and reboots. That is phone cannot be turned off, it s somehow turn itself on again.
Whats the reason of this problem ?
In another forum one faced with the same problem said that it turned out to be normal when the battery is erased but the problem is occured again after docking.
micro usb connector
I droped my phone in the water, got it alive again, but with all the error(overheat battery symbol, no stable usb connection, reboot when i power off, 100% charged not going away) replaced the micro usb connector with a new one.
Some problems are gone but i still can't connect to pc (kies, debug etc), poweroff problem still happen sometime.
Conclusion: It is not only the usb part of the phone that are causing this problem.
But I do belive its a hardware problem.
Have you phone maybe got to much to drink too..
usb port???
I've recently been experiencing the same problem
When I turned off my phone it switched on again!
And removing battery and plugging it back it also just reboots the phone.
Sometimes the USB connector and charger are confused
Do solved the problem by changing the USB port?
plz help me
Thank you in advance for helping me
This is definately a hardware issue. Clean the usb connector, failing that it will need replacing

Yep, I'm having another round of issues on my One.
Just some information:
Running stock ROM, bootloader locked (not "relocked"), S/N HT346(...), Quick boot OFF, previously sent in for repair.
I believe this has been brought up before, but here I go:
I pulled the phone off the charger this morning with a full charge. However, Car mode unexpectedly opened up. I found this odd, since I'm running a stock AT&T ROM using the Sense launcher, which means Car mode is nowhere to be found. The device also reported using an "incorrect charger" or some other thing. I use the charger that came in the box with my phone. I assumed it was a mistake.
However, in my infinite wisdom, I decided to brush it off and went on with my day.
Usage patterns normal, maybe with a bit more GPS and camera use than usual, but more or less a normal day.
Come back home, plug it in. Phone will not charge. I do not believe it's a hardware issue. Why?
Troubleshooting time:
Plugged into another outlet, will not charge.
Switched wall warts. Will not charge (I have a few from older HTC phones and a few from other Android devices).
Switched USB cables. Will not charge (tried combo-ing with wall warts, same result).
Plugged into PC. Will not charge AND does not recognize USB connection (both ends). Tried with several different cables, no dice.
Rebooted, no dice. Did it again (and several times after that), no cigar.
Safe mode: Nope.
What works?
Connect via fastboot works (so "FASTBOOT USB" works)
It WILL charge when powered off.
Now, as the title states, I noticed the LED blinking when the phone is powered off and plugged in via AC or USB.
The orange LED will light up for ~6 seconds, dim down (to the level of brightness that would be considered "normal" for the phone) for ~6 seconds, then turn off. The process repeats after the LED turns off for about 5 seconds.
Any ideas on why this could have happened (including my own stupidity) and what I can do to solve this problem? I'm going to send it in to HTC if nothing gets it working again (and has it stay that way).

I have the same problem, and started the same way. Anyone found the solution?
Please help.
Thanks.
Have the Xperia Z tablet in stock ROM, unrooted, everything stock ... and a couple days ago out of the blue the tablet has stopped charging.
Even when I plug the USB cable in, the LED does not come up. Looking at Settings->Battery it shows a slim line under "Charging" only. Tried different chargers and different cables, same thing.
If I power off the tablet, and plug the charger in, now the LED lights up and the tablet charges.
As soon as I power on the tablet, the LED that was on goes off immediately. With the tablet turned on somehow it cannot detect the charger at all.
Tried rebooting the tablet a few times and didn't help.
Anyone had the same issue?
My next step is to use the Sony Companion software to repair it but not sure if it will wipe out my tablet ...

It's weird that it still charges when its off. I had a problem where it wasn't charging at all, and the motherboard got fried apparently, and Sony gave me a replacement.
I googled some, and people having similar problems as yours (on Sony as well as other androids) ultimately had to get their phone repaired/replaced unfortunately. For example - http://talk.sonymobile.com/t5/Xperi...Z-only-charging-when-switched-off/td-p/513665
I suggest you take a backup of all your data while this phone is still working!

Thanks, I've since reset the tablet a few times and it's been charging again... No issues thus far so... Seems to be all good got now
Hello,
I have a really weird problem with my phone for several months now. I use Zenfone 5, and my warranty is probably void already, but I could not use it anyhow (it is in a different country). I tried contacting the official support, but they just said to send it in for a check up, which I could not at the time, and cannot now either.
The problem started when I plugged in my phone in my car using third party car charger. It worked with other phones with no problems, and the output should be OK. When I plugged it in, the light on the charger went off, and the phone turned itself off without any notification. I tried to power the phone on with no success. It just vibrated, and remained off. Later I disassembled the charger and found out that the safety fuse has melted.
I went to my house and plugged the phone in, and it turned on. But the problem was, and remained to this day, that the phone thinks it is charging even when it is not plugged in. The phone charges normally, and battery life is ok, the phone normally goes into deep sleep mode.
The phone won't power up without charger, and the USB OTG obviously doesn't work. But there are some curious things about this problem.
When I took my phone apart and disconnected the battery for 30 minutes (it is non-removable), after I connected it back, the phone turned itself on (without the charger), until I tried to charge it, then it went back to only powering on while on charger. The constant charging thing, nevertheless, remained all the time.
Sometimes when I plug in the cheap USB OTG converter, the phone stops charging notification. When I unplug it, it goes back to charging.
I have no clue what could be the problem, and which part (the usb board or the battery) could be faulty.
I also tried hard reset a few times, with no success.
Thank you in advance for your answers.
Bump? Anyone? Any clue?
Is there any way to change kernel so it doesn't register charging if there is no current flowing to the phone?
And which type of battery connector is this?

Hi,
long story short: I connected my Z5C to a bad (apparently, I don't want to test ) charger and now I have some strange issues. Is there any change that my h/w isn't fried?
Full story: As I said I connected my Z5C (newest CyanogenMod provided here) to a charger and it instantly did a hard reset. Afterwards it did turn on and continued to work for some time. As I was on the road at that time I could not charge it elsewhere and later that day it ran out of power. When I tried to charge it with a known good charger some days later, it did not boot. I suspect the boot process to healthd or whatever draws this cool animation takes more power than my working but small charger provided.
It did charge at my laptop, especially when I put it into fastboot mode.
Now thats where I am stuck; the phone won't turn off completely and keeps rebooting when I turn it off (via os menu or hard reset, no chance).
I can charge it after it runs out of power (managed to charge to 100%), but it won't charge if I unplug and replug it. It is not recognised by a pc after I reconnect it one or two times (checked with device manager and lsusb), only chance to get to fastboot or flash mode again is drain the battery to 0%. It does show a loading animation and I can boot into android from there. Battery drain in Android seems to be a little higher than usual (100 to 0 after 2 1/2 days of pure standby without any radio stuff on).
I have already reflashed the original Sony firmware and erased everything that came to my mind (cache, data....).
Any hope that I did not kill some piece of hardware?
Thanks for your answers, any help appreciated
tell me more about your z5c's software, why you mentioned Cynogenmod? did you flash it with cynogenmod?
seems to me that z5c was running on custom rom and did not support fast chargers and bricked your device!
if that so, try flashing it using flashtool with original stockrom.
i don't wana go in to details however there is possiblity that battery.sys file is corrupt and atleast I was never able to fix my LT18i when it got bricked and battery status use to become zero in 2 seconds and android keep rebooting, later it got silent for good! no charge no nothing and i still have the device sitting. I was running it on coconut (cynogenmod) when all this happened!
Thanks for your reply.
The charger was no kind fast charger, just a common 12V to USB adapter with an output of 800mA (when it worked). I was running CM 13 when I connected it to the bad charger, but as I mentioned I have since then reflashed it with Stock ROM. No real improvement.
I have continued trying and I found out that the device seems to believe it is still connected via usb.
Code:
cat /sys/class/power_supply/usb/present
gives me "1" with nothing connected, can you check if this is normal?
The file is -rw-r-- r--, would changing its value change anything or is it just some kernel thing (can't check, don't have root permissions now as I flashed Stock ROM)?
Also after I charged it on my PC today it still shows me the notifications for USB connection and adb (I can add a screenshot if necessary), also looks like it still believes to be connected.
It seems I found the solution: I was playing a bit with a USB-OTG adapter (the ones to connect regular usb devices like keyboards or storage to your phone). After I connected a USB keyboard I tried (just for fun) if the Linux "Magic" SysRq hotkeys were enabled. So I did press Alt-Print-o, which is the Linux hotkey for "turn off now". It did not turn off, it also stayed off (no instant reboot). After I started the phone again it also properly turned off via the power menu!
I will have to test whether the charging issues are fixed, too, but as far as I can tell the problem seemed to be something software-related
Sadly did not work for long. I think I will go for official repair, think this is still cheaper than buying a new phone (after completely killing it with some DIY "repair" attempt). This annoying brick simply does not turn off, no matter what I do (apart from draining battery to 0%). Guess its my fault, still to afraid to try that broken charger again.
