Hi all, picked up a GS2 the other day which had the USB charging issue. i.e. Plug charger in and it either wont show up or gives false data and unplug it still shows charging. Also, the battery temp sign showing and battery pull leaves a fully charged battery dead!
Looked around on here and on the net for various causes and possible fixes. These ranged from changing ROM, replacing the USB charging port, calibrating the battery, any number of different things etc etc.
So in theory, it is either a software issue and/or a hardware issue! But to me that made NO SENSE. It couldn't be both, well maybe for a small % of people it could be but for the majority, it had to be something else.
Well, as it would seem from my findings, in my case, it was something else. It would appear that the MODEM/RIL combo is causing the issue.
I tested this on my non-functioning device by flashing a new MODEM/RIL combination and then re-flashing the old one just to check. The old one has the issue, the new combo it is gone!
So IF you have this issue, try flashing a new MODEM/RIL combo and see IF it fixes the problem BEFORE spending any money on repairs.
As IF by some wacky coincidence forum member hawkerpaul has created a thread just today with CWM flashable MODEM/RIL's combo's, find them herehere
Hope this solves the issue for you as well

i had this problem since i got the universal which is about 6
months ago, the problem is that when the battery is 100% the green led is stuck even when i remove the charger, and in the power settings "charging" wont go away, and the battey is dead in less than 3 hours on standby, i tried another ROM and another battery but its no use, is there any solution, i really need help.
thanx in advance
Have same problem... any help
Probably problem with M/B, small chip that control charging. But check the WIKI first I think I saw something about this problem.
pl chk all radios are off. I had same problem last year but in my case I was using whatever source of power such as car charger, Inverter, ect. I'm using only my laptop now. Charging Voltage can damage your batt real fast.
The charge control chip is in the battery pack, not on the mainboard. While it is possible that the OS is reporting false based on the data it receives from the chip, it is unlikely since he says he tried other ROMs as well, which would have eliminated the problem.
I would have also thought of a dying battery, but he has tried another battery without success.
My best guess is that the power routing chip is either damaged or miscalibrated, and evaluates the received data wrong, leading to excessive power drain, even in standby mode, for example by keeping WiFi powered, and not instructing the CPU to throttle down.
The "stuck" LED, however, indicates a different problem, as LED control is a separate aspect of the motherboard firmware.
I would recommend backing up everything, and using mtty to format the DOC, which should erase everything. After that, install you ROM of choice, and if the damage is not hardware-based, it should be fixed. If it is hardware based, then I'm afraid only a qualified service can help, most probably the device vendor, if the warranty is still valid.
I have searched all over the web and haven't found this pop up that much, I can't find anything in particular that could be causing this wakelock. Once the wakelock starts, it keeps the phone awake 100% of the time. Running CM11 M2 snapshot with various kernels (stock CM, Hells core, AK at the moment) and it appears with all 3 kernels.
I'm running BetterBatteryStats (doesn't show anything aside from pointing out it's 'Slimport Wakelock' and Wakelock detector doesn't even register 'Slimport wakelock' and doesn't seem to show anything rogue....
Any help?
same here
I have the same Issue. though my OS is vanilla 4.4.2
Iv'e recently had to change my usb socket because phone was not charging. I think the issue started then. did you mannage to solve yours/did you also change your usb/charge socket?
A
I have the solution guys... Though its hard to explain, its not very hard to accomplish.
I took my n4 for another try in a different lab. The technician from the start suspected it's not something in the charging port itself, so he asked me to leave the phone for him for a few days.
After 4 days of trying and learning, he managed to find that the problem is in the socket on the board itself is causing the problems, along with the charging port, in my case.
He replaced the port on the board itself and the problem is solved.
Eventually, I paid 40€ for this problem, not very high, beats the other option (buying a new phone)
Try it guys.
what do you mean the socket? is this what he replaced?

I have searched and searched and searched, only finding unhelpful suggestions from people not too qualified to offer said unhelpful suggestions, haha. This bastard Moto X will not charge, regardless of charger/cable used (OEM Turbo and regular), no USB trickle charge, and I caved and got a new battery despite knowing better and it still won't charge. It stays on while plugged in and runs until the percentage reaches 0% (rate of discharge isn't always consistent). I've tried a whole host of dumb tricks like draining battery to 0%, selecting "Power Off" from fastboot, and holding Power/Volume Down for five minutes. Doing the latter seems to be the only thing that allows it to get a charge, but it's kind of wholly impractical to do that every day for who knows how long to make a difference. Also did complete factory reset and fresh reinstall of both factory and cm13 ROM and clearing ALL the caches, still to no avail.
So because it will slightly charge in the constant fastboot/reset process of holding Power/Volume Down, I've come to the conclusion that it's a kernel thing because of a damaged component on the board. Biggest issue is that the battery is reported as "Cold", with a general temperate reported by multiple utilities at -32 degrees. I can't upload screenshots at the moment, but TWRP reports system temp as a massive string that covers 2/3 of the bar up top. So for whatever reason the phone isn't getting a reading from the battery temperature sensor, and it's refusing to allow the battery to charge. I've been searching like crazy to find a way around this, be it editing the kernel to ignore temperature, or finding a schematic to know where to look for related circuitry responsible for this. I DID find a single component that has been broken from the previous owner tearing into it to replace the screen, but it's up near the button connector and just seems like an inefficient place to take anything relating to the Power IC. Regardless, since I can't find any way of identifying exactly what it is and what it does, I'm not sure how to handle this. Any flippin' suggestions?
tl;dr - I had pizza leftovers for breakfast and I regret it.

DID YOU FIND A SOLUTION? I'm facing the same issues with my moto x pure edition (XT1575) after a screen replacement. Ampere aplication says the battery health is "Cold".
I never did, unfortunately. I tried a different battery in the event that some onboard IC was damaged, but it performed the same way. Whatever component was damaged seemed to be responsible for relaying pertinent information regarding battery temp readings; and without it the phone was getting that -32 reading which was beyond a safe/efficient range to allow charging (presumably). In my research, I think I remember it being possible that fiddling with the kernel itself to bypass battery temperature requirements is possible, but that's beyond my level of knowledge and runs the risk of being potentially unsafe since all it takes is one instance of getting too hot for the whole thing to go up in smoke. As frustrating as it is, it's not worth the potential damage to the device and/or home.
Not to say that your issue is the same as mine concerning cause, but the end result of how to bypass it would more than likely be the same :/
Same issue... Well... On my way to it.
I mean, my XT1575 will only charge if I lift the micro usb cable in a very very specific way. And everyday that passes, it's getting more a more difficult to find the right spot

I had that exact issue with the included 25W quick charger after a while. Switched to another charger and cable and the problem was solved for me.
I'm in stock ROM. Suddenly my phone is not recognising charger and earphone unless I restart. But still, QC is not working. Phone is charging real slow. I've tried different Qc3.0 chargers and different cables, but the issue is still present. Battery life is good in stock ROM, so really not interested in changing ROM.
I can see other people also facing this issue. Anyone have solution?
If you are still on stock, try a factory reset. It sounds like you either have severe corruption or your battery is dying, or your usb card has a shorted wire.
The main problem with stock is the charging, generates too much heat.
Galactic Stryder created a kernel made to resolve stock charging issues. To be able to install it, you would need to root your phone and install TWRP recovery. I would try the factory reset first.
Should you try this option, you will need to post in the forum for support and instructions.

thanks! will try this i have the same issue... never rooted device !
Please can someone help me with a problem I’m having with my Samsung Galaxy s5.
I put my phone on charge before I went to bed and when I woke up it was still showing a red LED. I knew this was wrong because it should have had enough time to charge and turn green. I had not powered the phone off before putting it on charge and I plugged it into the same USB 3.0 charging lead I have been using for the past six months. I unplugged the phone and pressed the power button to light up the lock screen but it didn’t light up.
I’m thinking possibly something has either shorted or over heated and fried something either on the charging port assembly or one of the chips adjacent to the port while the charger was plugged in. It seems like only a trickle of power is getting through to the phone. When I plug a different USB 2 charging cable into the phone, without trying to power on, the charging icon appears but shows no charge at all in the battery.
I have also tried the spare battery I have but it’s still the same. I know the spare battery is 100% fully charged because I store it in a separate charging/storage box which shows a green LED when it is full. In fact the one which was in the phone at the time is also fully charged according to the charging box. Neither battery has got warm at all inside the phone. I’m confident both batteries are fully charged and totally fine and the problem isn’t with the batteries.
At this point I removed my sim card and also the MicroSD card. I needed the sim to use in my spare phone and I wanted to see if the sd card could be causing the issue but after again trying a normal reboot it made no difference.
I’ve tried several possible things I found on google but nothing has worked. Between each different thing I tried I had to remove the battery for 10 seconds and insert it again to get it out of the boot loop so I could try something else.
Initially when I tried booting into safe mode, then recovery mode and then download mode it brought up the screens for those but in each case after a few seconds the phone powered off and went into a boot loop so I couldn’t attempt any recovery options such as clearing cache etc. Now I cannot even get it to start any of those modes at all and all that happens is the phone does a little vibration, displays the Samsung logo and then just boot loops no matter what I try.
I have tried removing the battery and leaving the phone for a few hours then powering on again but it still just loops.
I have tried pressing and holding Vol-down when plugging it into my PC using a different USB 2 cable and windows acknowledged a phone was plugged in but said it couldn’t connect or recognise the phone and suggested the phone could have a fault.
I don't know if maybe my USB 3.0 lead has a fault that could have caused it or if there could have been some electricity spike while the phone was plugged in, or as I said a component has just fried.
I strongly suspect this is a hardware fault and not a software fault but as I’m not a phone engineer I have no idea about how to trace any possible hardware issues or what might have gone wrong. I would really appreciate any help or suggestions about what the problem might be as this has been a great phone for the last 2 years since I got it and I’d be sad to have to junk it and buy a new one.
Thank you.
I would not junk it yet......
You had mentioned that you go through a lot, just to get phone into Recovery ( " Initially when I tried booting into safe mode, then recovery mode and then download mode it brought up the screens for those but in each case after a few seconds the phone powered off and went into a boot loop so I couldn’t attempt any recovery options such as clearing cache etc. Now I cannot even get it to start any of those modes at all and all that happens is the phone does a little vibration, displays the Samsung logo and then just boot loops no matter what I try." )
OK, just my 2 cents here on this... Why not trying to goto Recovery by pressing and holding the Volume Down (vol-); Home button, and The Power button all at the same time. (yes, if you have a Recovery, and its works, you should be able to boot right into Recovery- >Now, (I would, cause I've been there..) I would also have a PC going with Odin open (Plus the Latest Stock Rom) ... If it works, you would flash the Stock ROM, to clean up anything, giving you all stock, but you can change that of course ...then go from there...
Second, if you can not still get to Recovery.... Have you tried a Stock USB Cable, only asking.... Obliviously something is a miss... with Power... IF phone is off, and you plug it to a power source ... then system has power, and these can power up with just the usb cable, without having the battery in..... Been there. Can add the simple fact, if using just a Micro SD cable, they can bend the Power Board. Believe me (Had to fix the Wife's S5 a few Frinkin' times....) That is why, I say using the Stock Cable, or even a USB 3.0 Cable (like the stock one) does help with power issues when the Micro has bent up the power board...
Will check back and see if this may have you to Recovery or fixed... sure hope this can help you out
Thanks for replying godofsalt.
At the time the phone was plugged in to my USB 3 lead which charges faster and all I can think is that perhaps there could be a fault with the lead or the higher ampage of using this lead caused a circuit to burn out.
I have around a dozen USB 2 leads and I've tried your idea with 3 different ones but none of them will fire up the phone at all with the battery taken out.
I am sure this is going to need some kind of replacement either of the charging port or the motherboard. I don't rate my chances of trying to do it myself and I don't think it will be economic to take it to a shop so I've found a better option by buying the same phone which is second hand but in good condition. That way I know I have all the additional accessories already for probably the same price any shop would charge to fix it.
In future I'll stick to using a decent USB 2 lead on the 1 amp charger I used to use before and hopefully this will not occur again.
G500F battery graphic/boot loop
Had the same problem a few days after installing a 9.0 Rom. My battery is brand new and all cables aren't too aged, so I thought this had to be a physical fault of some kind, but then I had the thought to flash an older bootloader and just like that my battery started taking a charge again and I could boot up. Switched to Flyme os for a while the went back to 9.0 again, with the lastest bootloader and the thing stopped working again. Don't know too much, but I'd try and flash a different bootloader to see if there's any difference. My device failed right at the Galaxy logo, then looped the charging graphic endlessly but would strangely go into download mode and not fail. Don't know if this helps, just thought I'd share my solution.
Thanks for replying henderia93.
My symptoms are very slightly different in that the phone couldn't maintain any of the modes I tried for more than a few seconds before going back to the boot loop again so there was no chance of trying any software fixes including flashing the ROM. Now it won't enter any of those modes at all. I'm certain that's due to only a trickle of power getting through to the main board, not enough to maintain any recovery modes, so there is just enough power for it to attempt to boot, but no more so it just keeps looping, most likely caused by something that has blown while on charge.

I ha e taken so many of these a part... Like I may have mentioned, there is a Board, just for the USB (data and power (i still have 2 of them)).... In short, you really have to pretty much take the phone a part. Being very careful with the Screen, and the "Sticky" LEDs and the Home button. There is a lot to it actually.
Like I said, been there done that... Cheap to get, takes some time but it is possible to replace that board. It's a separate board different from the actual main CPU board.
I would have to find it, but I had a manual, for taking these a part.

While I've been looking for answers about this I've seen teardown videos for the s5 so I can see what the port assembly looks like with it's little PCB behind it. As I have a replacement s5 on it's way all I need to decide now is whether to keep the old handset for spare parts or see if I can follow the teardown video to try and install a new port assembly to get the phone working again as a spare.

Yep, me too, seen many vids on the tear down. I decided to go a bit more, IMHO, to have an actual manual, PDF, when I did my first one, many years ago. So, can read, and use photos wisely. Seen too many Utube crap, where the break it, destroy it..... crazy!
Well, at this age, not too sure what to do my self. In our case, our present service is cheaper to Keep these. Grandfathered in, and we pay a but less, than going to any other carrier. Plus, these newer phones are not cheap at all.
True, it up to you. hope all goes well.
Sorry I am a novice so please excuse my question.
Are you assuming that the usb port is shorting even when no usb cable is inserted? As you put a fully charged battery in with no change it would seem that the act of charging is not involved.
Have you tried a voltmeter to check the voltage at the battery charging pins?
Have you tried to check the voltage at the two pins commonly used for a wireless charging adapter (to the upper left of the battery) to see what the voltage is?
Sorry if I am off base.
