So the last couple of weeks it seems my player 5.0 is really picky on what kind of charger will charge it. At first all worked and then no wall charger would work only through USB. Then only a few cords I could barrow from friends now none at all but once in a blue moon. It will not even attempt to charge on 99% of cords. I have recently found out if my device is completely dead I can plug it in and it will do nothing but reboot till it completly dies. If I let it completely die and not unplug the cord it will charge and reboot 100% after a hour or two and be fine again but does n longer charge unless its own ignorant demand. I haven't tried switching roms cause I'm quite content with my current one and has no other problems software visible so I was curious on if it was hardware instead any ideas guys?
I've seen mixed results trying to charge with cables other than the one that came with the player. Sometimes they work fine, other times they work for a while then wont charge it. Most of the time, data transfer works fine. Might be some weird voltage issue or something with the hardware, but I saw issues with the Stock setup.

I think this can only be hardware related, right? Does the micro-usb port still look right? You could send your device if you still have warranty (or if you really need it repaired).. That will take some time, though
To clarify, is this distinct from the standard bootlooping problem where a device will continuosly cycle through a partial boot if it's powered on (or reset) while connected to another computer via the usb cable? If the battery is too weak to last through a whole boot process, the charging screen will flash on and off as it moves through that partial boot cycle.
If that's NOT the problem you're experiencing, I'd suggest booting into recovery mode and wiping the battery stats (it's under advanced in most CWM-based kernels).

Thank you wiped battery stats and my.cord I though I had wasted 20$ on started charging it right after reboot
Glad that worked. Odds are it was actually charging the battery, but android had the wrong info, so it wouldn't show as charging or warn you when the battery was getting low. This is a fairly common occurrence for me, which is why I never trust the battery indicator, and charge it whenever possible.

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.

same issues to me... I'm trying to fix it flashing a stock rom without good results yet In the meantime I'm waiting for a USB jig from ebay before to send it to technical service
I have a I9100M(BELL) flashed with cognition 1.32 with same problem.
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.

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

So.. I have googled the crap out of this problem and seen loads of issues raised, but nothing solved.
I am coming from a Dell Streak and grabbed me a galaxy s 2 from craigslist a couple months back.
It has been running fine and I have tried a few roms/kernels and a few days ago I got the following error:
When charged to 100%, I get the notification to unplug, when I do, it sticks. No big deal but even when the phone battery has dropped to around 80% it stays.
It does not go into MTP mode or think it is plugged in via USB. Although, before this problem originated, the phone continuously vibrated between charging and not, when not plugged in.
I have calibrated the battery, tried a mixture of roms/kernels and I am now on unrooted stock. The problem still occurs and sometimes it does not recognise a USB connection, like today.
Probably worth mentioning that when turning on (and not plugged in) the phone does not turn right on, just boots into the battery screen and flashes between the battery charging and the overheating symbol.
Anyone got any ideas?

Turn off the phone and put it on charging. Once it beeps that its fully charged, quickly unplug the battery for 5-10 minutes. Should work and 'recalibrate' your battery

Thanks, giving a go now.
Do you need root to calibrate though? I am on stock firmware and not in front of a windows machine to use ODIN.

OK, charged to 100% and got the full notification.
Left battery out for 10 mins and whacked it back in.
Turned on and it went to the overheating sign again.
Booted into the samsung recovery and I can boot into android from there.
Battery says it is as 88, cannot calibrate as I do not have root atm.
Any ideas?

Get root and use the battery calibration tool from the market. The best idea so far. I suggest rooting with CF-Root, its fast and easy - its basically still your stock kernel but just with root.
If you really need the warranty or you'r scared of root you can install cf-root, calibrate the battery, then re-flash a stock kernel (unroot)

If i helped you, press thanks. Thanks.
Done and done.
Calibrated, even bought a new battery. Tried various other roms and appears to be an issue. Phone knows when USB is plugged in but does not seem to recognise the unplugging of the charger. And stays at 100% for a while before dropping down to like 80.
One thing to note is that this seemed to happen around the time of buying a dock for the samsung from Amazon, by Kidigi. I plugged the phone in to the dock without a USB cable connected to the dock and the dock LED lit up, making the phone think it was charging. Is this likely to have caused it/messed up the micro usb forever?
Thanks again guys!
well i think ive figured out what the problem was
Its due to overcharging or keeping the charger connected after battrey is full which has caused a hardware damage
im not sure if this is true but this is the closest explanation i can get the phone shows connected to charger even when diconnected only when i keep it connected for long time even after its battrey is full my usb connection has completely stopped working

well that the same problem with me when it shows connected to charger at 100% i restart it then the phone drops to ~80% battery although its 100% which makes the app battery monitor widget think i have a 1977mah battery while i have the standard 1650mah battery this must be the extra 20% which disappeared after the restart for me
I thought it may have been an overcharging problem, although no other phone I have owned has had this problem.
I let the battery charge all the way down (it stayed at 1% for about 3 hours) until it shut itself off. I left it on the side and it created a clicking noise, it was trying to turn the phone on as it knew the battery was in, even though it was depleted.
I plugged it in via USB to charge and it tried to turn on straight away. Shut it down and charged by plug until the 100% notification then turned on.
Still the same problem but one of my battery widgets warned that the battery was over voltage for a while before calming down.
If the phone cannot be off with the battery in, what could be causing that?

It has been known to be caused by a defective circuit board for the USB connector.
So, it needs a samsung return, I assume?
i have the same problem with overheating and usb plugged when there is nothing connected
i changed the usb port from the phone but it still having the problem!!!
i will try to put a new battery and see if it work and after post a reply
I read loads of similar issues, but mine is a little different:
I heavily used my stock-rom, unrooted phone today, recorded long videos in Full HD, when I got back home, I had 18% battery, plugged it into my computer's USB to get the videos (unaware of the issue of insufficient current on USB ports) and windows did not recognize it.
I then unplugged it planning to plug it into the wall socket, and when I woke the phone, it died on my arms
A little annoyed, I plugged it into the wall socket, and got the slow, orange blinking LED, and was not able to turn the phone on. After 30 minutes, the LED stabilized and it seemed to be charging (while off), so I left it there for another 20 minutes.
When I tried to turn the phone on, it worked, normally, but showed 2% battery life remaining. I had Wi-Fi on, but normally it wouldn't be an issue, so I left it charging for another 20 minutes.
I then woke the device and it showed 1% battery left! While plugged in! I tried to wake it and it died again.
I left it there for an hour or so, turned it back on, 6% battery left, I then turned Airplane Mode on so it would charge faster. After 10 minutes in Airplane Mode, it still shows 6%. It is not charging, I'm using the original HTC charger and cable.
It seems like it is not charging at all when on, and charging VERY slowly when off.
Tried a few tricks I read online, such as holding the volume up + volume down + power button for 2 minutes, but all I got was a steady flashing recovery screen, which says my battery is too low for flashing.
So the difference between mine and other posts is that my stock phone is turning on, but not charging anymore. If I turn Airplane Mode off, it drains itself even while plugged into the charger.
I'm really looking for a solution for this, instead of simply returning it (it's more than one year old, and I bought it overseas) or buying a new phone.
EDIT: Battery Widget app showed Charging Speed: n/a. Testing says battery health: good, 3666 mv, "charging" status
EDIT II: Tried running it in Recovery Mode, got a 3d exclamation point with a phone icon. Rebooted it normally, it turns back on, still not charging. This does not look good at all.
EDIT III: Read about Mr Hofs idea, of running custom recovery via the PC, but I can't get it to connect. Have newest version of Sync Manager yet windows says the "device malfunctioned" and could not be recognized.
EDIT IV: Done factory reset, no luck. Phone is still draining while plugged in. After 8 hours of charging while off, all I got was 40/50% I'm really desperate as the phone is virtually bricked and I need it for work. Willing to tip/donate to whoever finds solution, if that is ok according to forum rules (not sure)

Back to the blinking led
I tried plugging the phone into the computer's USB port, got the red blinking led again. Held the volume down + power button while connected to the PC and it seemed to be constantly rebooting - windows popped up "device not recognized" several times and the power led started flashing much slowlier. Sometimes the lower leds would also flash. I held it like that for 2 minutes.
After a while the lower lads and the screen backlight lit up. I then realeased the buttons and quickly plugged it into the wall socket.
Now I have the fast blinking again. Awesome. I can't tell if I'm doing it right or brutally murdering my phone
You might just factory reset once your charged as .much as you can. I believe your problem. Is having to do with using or somehow got a bad current or USB port/cord etc. Anyway its software related and a hard reset doesn't help I'd RMA ..you go flashing mods to do yourself probably won't work especially if its hardware. Hope this helps. I say this as it happened to me. I used a lower amp wire charger socket. Same thing happened. After many hours of trying stuff. Factory reset never used bad or non OEM again. But in your case it may be just some IDD quirk. It happens bro. Hope you get it up and running. ..

Left it charging while off overnight, now I have 40% (!) battery. Any time I try flashing the default recovery, it'll show a red exclamation. The PC won't recognize it at all, even with downloaded drivers. And doind all that seem to have drained it to 30%.
Will try to get my important files and then factory reset it.

Charge to 100%
Try a different charger
Try flashing a different ROM/kernel
Try flashing RUU
Contact HTC
That's what I would do and the order I would do it in. Leave it alone until it is charged up to 100% before you do any of this though. Even if it takes a week. For all I know, charging to 100% will reset the charging circuit. I doubt it, but who knows.... Stranger things have happened.

Well this is awkward.
After many days, and since HTC is not present in Brazil anymore, I have no ways of contacting support, I gave up, bought an S4. After two days with my new phone, guess what? The HOX+ charged 100%, and it seems to be discharging normally. GOD DAMMIT.
So, ridethisbike, your suggestion worked, kudos for you and boo for me for not being patient and giving a shot.
Out to look for a buyer then. :silly:
Everything indicates my Galaxy Tab p5113 is charging properly- the tab tells me in several places its charging, there is a flash symbol on the battery. Charging via PC is no different. However, in reality it's not charging at all, the battery percentage is always going down.
Ive tried (1)different batteries, (2)different chargers and (3) different firmwares - the result is always the same - a drip drip of the percentage charge.
Not only does the Tab tell me it's charging, I am also not having any problems with the data connection - I can move stuff between PC and Tablet and vice versa without any problem.
Where can I go from here? Help please.

I'm not sure.. But I would wipe cache,dalvik cache,and reset/wipe the battery stats in recovery and reboot. If that doesn't work see if something is running, pulling away charge ( I doubt this,but had to put it in ) You said you changed firmware..did this include a kernel change. If not I would grab a stock kernel or at least one you know works well. Double check USB pins are not bent or touching/maybe dirty. My e4gt showed it was charging all the time once.. I could still charge and transfer files. Ended up being a bent USB pin. I fixed it with a tooth pick and a pair if tweezers..lol. Take the battery out if you plan on sticking anything in the USB charging slot..Sorry I couldn't be more helpful
Just in case there was a problem with the Charging Port I swapped it with another one I had which I know to be working. This hasnt made any difference.
I am happy it's not a kernel problem. I was running a stock firmware, I then updated via Kies to another stock firmware. I then put on CM 10.1. In all these cases, whatever the firmware, it didnt make any difference, the battery didnt charge.
Ive tested the battery with a multimeter. I know it's not charging despite the device saying it is. In this circumstance I dont think that a re-calibration is necessary.
Im feeling at a loss. Despite trying different chargers, different firmwares, different batteries and different charging ports the device will just not charge. Im think the problem might be on the motherboard (but not sure where).
Comments appreciated
Same here with my Galaxy Note 10.1. This is a unit issue. Not a charger or battery issue. After some lengthy time it does manage to get charged and everything is great again...for awhile. I have done a lot of research and found no solution. I have seen posts where people have changed the battery and the charger with the cable and same problem persists. Samsung seems blind to the situation.
Try this with the tablet plugged in to power: Hold down all three keys (vol up, vol down, power) until the tablet resets. I think this resets the charging logic and may work.
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.
