So I woke up this morning to find my Tab drained. I plugged it in for half an hour, then when I picked it up I noticed there was no charging indicator (the green liquid battery thing). So I thought maybe I didn't plug it in right. I reattached everything, tested the charger on another device, then plugged it back into the tab for about 2 hours...still no juice. I tried powering on and doing the reset thing. still nothing. I brought it to a Samsung service center and they said I have a faulty motherboard. Now I'm wondering how the hell that happened when I've been using this device for about 6 months (only 6 months) without any issues, no overheating or strange reboots or anything, and now just like that I have a motherboard issue? The kicker here is that they're charging 75% of the tablet price to fix it! What gives?! I purchased it from a non-samsung mall store so they said I can't claim warranty. I popped the back off and did the battery pull thing and tried to charge - still nothing. Did I buy a device that decided it was a lemon after 6 months light-moderate use?
Anyone else have this happen? It's never been dropped or anything and I was on stock firmware with nothing but root.
In the UK, If your tablet goes faulty in 12months your guarantee is with the place you bought it from, not Samsung.

It's ALIVE! I thought I'd get a 2nd opinion on my Tab since the guys at the Samsung service center popped it open anyway. Went to a generic phone repair store, all they did was hook it up to this box thing, and it came back to life! The guy said something got corrupted and just re flashed everything to stock rooted. He charged me less than $20 and I have a working Tab again. Obviously the very first thing I did with my resurrected device was to call Samsung's hotline and report how this one service center was trying to scam me into buying a motherboard that cost nearly as much as what I paid for the thing brand new.
Some li-poly battery have an protection circuit built in, if the voltage falls below a certain level say 2.5volts per cell, it disables the battery, if you connect an meter to the battery you will get 0volts , you need an li-ion charger that passes an higher voltage that resets the battery and allows it to work again, I wonder if this is what happened.

Did they connect via USB or to the motherboard?
@tinderbox could be...must have over-drained itself for some reason.
@ashyx I couldn't really see what he was doing since his work table was obstructed by a bunch of stuff and he had his back towards me, I just saw him grab this small black box, then minutes later he showed me that the tab was already powering on though couldn't get past samsung logo, then he went ahead and flashed to stock.
Reason I ask is I wonder if he used a jtag box to ressurect it by reflashing the bootloader.
If he did there must be jtag points on the board as it can't usually be done via USB.
Pity you didn't ask what he actually did as I'm intrigued now.
Did the box look like this: riff box

Exactly the same or just similar?
yeah i think so... it had similar ports, though not sure about the outer shell of it... i think it was smooth all around with no ridges or anything, just a little black rectangular box.
Sorry to revive an old topic, but i thought i'd do an update instead of start a new one. Tab S died again and I'm now convinced it's over-discharge, as I left it at about 20% and forgot to plug it in before going to bed. Woke up with the tab drained, not responding to any button combinations, not charging with any of my chargers that tested ok with other devices.
Instead of bringing it back to the technician, I thought I'd try mcguyvering the damn thing. I opened up the back, pried the battery terminals up off the board, lifted the battery out, and with a spliced USB cord hooked up to a powerbank, I gave the battery terminals a direct zap, inserting the exposed USB wires into the battery terminals. This took some trial and error as, I didn't know which wire was supposed to go where, but finally I saw the powerbank leds blink, indicating it was discharging into something. I held the wires in place for about 5-10 minutes, noticing some heat on the battery by then. I reinstalled the battery back into the tablet, closed everything up and tried charging again and...hey presto! the tab started charging. :victory: Let it charge for 2 hours and powered on like nothing happened.

I don't recommend you defibrillate your device's battery unless you know exactly what you're doing and are fully aware of the risks. (I didn't know what I was doing at the time but I was so frustrated at that point I didn't mind if the battery blew up in my face.)
Mine just dead last night while CHARGING (turned off at 13%).....
And refused to turn on till now (still charging and both warm (charger + tab)...
I even plugged an ampere meter to really know if its drawing any or not (it is, at 5.2V 1.7A for 15mins)...
And still no luck
Samsung's device become more ****ty each generations..... Esp the battery...
This one is the replacement batt they gave me after 2mos of usage for infamous Tab S battery issue...
I saw a video on youtube, a guy had a dead 10.5" T1 he took the back off and connected an 1amp microusb charger pcb to connections directly to the battery under a piece a tape, I bought a couple of the microusb charger pcb`s from ebay for 0.42p each in case mine goes dead.
EDIT: I found the video.

Samsung tablets only have issue with battery connectors. The white connector with 6 wires has loose connection, the black connector soldered to mainboard has cracked solder joints. New battery won't solve problem if you don't fix these two flaws. Resolder the battery connector will fix most of problems: not charging, reboot, flickering, auto shutdown.
I posted more details in the threat: flickering screen.
so the problem is Samdung's QC....
anyway no more somedung, I switched to Xiaomi Mi Mix, still preordering from China.....
You have to watch these chinies owened tablet and phone manufactues, they have been found to come with built in spyware, sending copys of all your texts ect back to china, it`s been in the news that last few day`s
Lenovo notebooks had a spyware app and Lenovo had to issue insturctions on hot to remove it once it was found.

That's OK, I can scan and remove all those spyware.
Still its better to have it properly supported with actual updates (older phone still got all UI + android update, hello MIUI 8).
Rather than using phone without proper software support....
Tab S - buggy and prolly the last MM update
Note 3 - useless LL update, very unstable, consider alpha
Note 8.0 - buggy last KK update, switched to CM13 and happy with it

Recently successfully replaced the LCD screen on my Acer A100. Device worked fine for some time after that repair. Wanting to get a secondary charger for use at work I went to radio shack. Sales "tech" tried several different adapters, found one that fit inside he port, but wiggled. She plugged it in but device wasn't showing a charge. Decided to order one from online. At home the device still would not charge with its own charger. Thought maybe the charger was faulty. Ordered two more. Still the A100 turned off when charger plugged in. Figured tech had burned out the a/c port. Ordered and installed a new one. Still A100 turns off immediately when charger is plugged in. I have 3 chargers now - same results with all 3. Have now ordered a docking station to utilize (hopefully) charging ability through 40 pin connector.
If this connection creates same shut down am I looking at a battery replacement? AM sitting at 33% battery level now, device shut down completely.
Acer wants 199.00 prepaid to submit to them for repair - this is more than I paid for the device! Not really an expense I am willing to pay if all it needs is a battery. There is no erratic behavior , just immediate shutdown as soon as a charger is connected. Any ideas?

If its doing it on 3 chargers its sounding more like a board charging circuit issue. You could remove the battery and then see if it behaves normally, that'll be battery or board right there. Or if you have a multi meter test output at the battery connector.

Don't have a multi meter. Tried connection via new docking station, got same response: device immediately shut off. Tried your suggestion, disconnected battery connected to docking station, got immediate shut off. Same with charger via a/c port. :crying: Mainboard is out? But Device responds and acts normal when in battery mode - or is this isolated to the charging circuit part of the main board?
Thanks for the suggestion!

Sounds like its tripping on the charger circuit and cutting out, like a breaker tripping. IMO look carefully for any shorts on the boards, even something stupid like dog hair can cause strange things to happen. A good blasting with air wouldn't hurt either. It could even be the dock port as it does charge from there and is subject to debris also.

Thanks again for more suggestions. Yup I have been over the board and all connections with a looking glass. Changed out the A/C dock port. My suspicion is that when the Radio Shack tech powered up the "Almost fits" adapter it blew whatever breaker the board has.
When I had it connected to the docking station with the battery disconnected, it powered on, then immediately shut off. So this definitely sounds like a "blown fuse". I completely disassembled and reassembled it again (except for the LCD screen) and checked all connections and plugs. Nothing visible to indicate a burnout or cross connection.
No odd smells either. Probably some teensy weensy transistor or resistor or something. I am not an electrician - just good at R & R.
Another visit to ebay and I am parting with 50 bucks for a "factory refurbished" motherboard. In the mean time, my beloved tablet will await further surgery. Will keep you posted. Board should be here by Saturday. I hope so - battery is down to 27%. Thanks again for weighing in!

To bad considering the crappy battery life so its not like you can charge some other way and swap the battery around.
Example, I have a bricked unit that charges but doesn't otherwise work, so I mean using my bricked board to charge it and the non charge board for use. The a100 isn't really a good setup for swapping around lol. I may actually be interested in that board now that I think about it...

If I could figure out a way to charge the battery OTHER than through the board - I would! Which got me to thinking. One COULD get a second rear panel, cut a door in it, install teensy weensy hinges or create a hinge with cloth tape. then make some sort of extension cord for the battery charging cord, plug it in to the "external" charging board and refill the battery that way.
With a working board and the right know how, one could just extract the board, put it in a box and make a charger out of it too.
But that is just my brain rattling around ideas. :silly: Hopefully this new "refurbished" mother board will do the trick and I will learn my lesson and NEVER let a sales "tech" attempt trial adapters! at 10 minutes to 9pm tonight it was in Texas....
Until I CANNOT use it, I didn't realize how MUCH I used this little tablet!
now it blinks orange?
Oh fer cryin out loud! The motherboard has arrived, I have installed it. Can plug n the charger and drop it onto the docking station and now I get the same response for both charging options: Charge LED lights up orange solid for just about 60 seconds, then begins blinking. Device doesn't respond when power button is pushed UNLESS it is plugged in, and then it just sits at the "ACER" screen.led changes to blue.
OK, wait a minute, this is the third time I have turned it on while plugged in. Acer screen has moved to Android, Device has started. Battery icon showing a question mark. 23%
Turned off, turned back on, now battery shows only 3%????
Think I saw something on the forums about that. will go on a quest.
Finally charging again!
Shhh, don't want to disturb my device....
Found folks on other forums with similar issues of the Acer A100 tablet showing only 3% charge. I removed and inserted the charging pin several times, the device would show solid orange led for about one minute then start blinking. Turned the device on when charger plugged in, unlocked the screen, then with device still plugged in I shut it down completely. Removed charger. Plugged it back in and so far the led is staying at solid orange.
Please keep your fingers crossed for me! This has been quite the roller coaster ride of discovery. Will leave it be for overnight (what is left of the overnight). Then peek at it in the morning. With any luck at all it will have accepted a full charge and I will be greeted with a functioning device! I almost want to learn a new trade..
well now that is weird, got up this morning to a nice blue charge indicator. Yay! Unplugged charger, press on button, hold, hold, hold, hold, hold and device does not start up. Dang it! Plugged it back in, led went solid orange, then started blinking again! Pressed and held on button. Device came on. battery meter shows 3% and a question mark! HUH?
have device plugged in, settings of course show android version 3.2.1 for this motherboard. Guess I need to upgrade it to ICS maybe that will resolve this weird battery issue? Hope soemone here has ideas, feels like I am soooo close to resolving this.
I read the upper posts.
Now I want to share my experience regarding battery load sharing:
I have allso problems to charge the battery.
I have on my tab, for example, 40% of battery power.
I turn my tab off.
When i plugged the charging cable in it shows me the orange led for load.
After two hours or more i turned the tab on.
It shows me not more than 40% but only 37% or so.
So not loaded. This was a bad sign....
I dont no was happend.
I get a little bit nervous but when the tab not get power it doesnt work....
After two/three hours the battery was empty.
Now i can only start my tab while plugged the charging cabel in because the battery will not load.
I have tried several options to find a solution (disconnect the battery, install a new battery, etc. ....).
My solution was fairly straightforward:
I open the tab. Look where the power comes in.
Of the charging socket go four (two red and two black) cable to the motherboard and from the motherboard it goes seven (two red, two black and for me not so important three other coloured cabels) to the battery.
I organized four thin wire and soldered it from the charging socket directly to the battery (of course red to red black to black ).
The result:
When i plugged the charging cabel in while android is running i get no information to load and it shows me not to.
But when i turned the tab off and on again it shows me that it has the battery charged :fingers-crossed: .
After on night while the charger plugged in the battery is fully loaded!!
And of course i get the information in android the discharging of the battery but this is an normaly thing!
So, the problem to load the battery for me is solved .
I hope it helps a little bit for everyone!

I really hope other isn't any voltage or amperage changes needed of that can blow that battery up real quick, plus it can't stop charging, you'll need to monitor that yourself.
Thanks for the info though, it does appear to be yet another somewhat common bug these have that can be addressed by a user if they feel the need to.

Not switch the charger off when the battery is full?
I think the charger there is a shutdown would otherwise overload the battery, right?
Or do this the motherboard?
Anyway, for me the tab is fully working now and if the battery is broken, it is not a big expense to replace them .

I was saying the board is in charge of cutting the battery charge off, not the charger itself so maybe keep an eye on it, its a good way for an explosion or fire.

A100 tablet not charging still
Frischies is much braver than I am.
Wiring the battery direct to the charging port- I would definitely worry about burning up the battery or causing a fire - especially while charging when I sleep. I have had more than my fair share of run ins with fire.
The Motherboard I ordered arrived and I installed it. It was listed as "factory refurbished", but unfortunately will not accept a charge. I thought it had charged overnight at one point, but all it does is blink orange and the battery reads 3% or 0%. Turning the device off when plugged in and doing a reset has not helped. The vendor has been gracious to do a replacement, so I will follow that route until I get a working motherboard.
I have discovered that the docking station will be a welcome addition to my Acer tablet paraphernalia! Although this model docking station isn't the one that allows HDMI throughput, it still will be nice for music, and other media. A Bluetooth keyboard and the tablet will offer yet another computer tool!
First things first though, get the tablet to accept a charge - until then it is a really wide flat paper weight! I am getting VERY adept at opening the tablet and removing the internals!
It is working again! The motherboard sent was defective but vendor issued an RMA. Received the replacement yesterday, installed it last night. Charged over night and fully functional this morning! Ahhh it feels good to have my little buddy back again. Didn't realize how much I used it, until I couldn't use it! Thanks to all for the help.

I bought a note 10.1 2014 Ed a couple of weeks ago on eBay. Not refurb and sealed in the box.
Devastated to find tonight, after completely discharged and shut down, that it seemed not to charge at all.
It becomes stuck on either the battery symbol, where nothing happens, arrow doesn't spin and no animation, or goes to the device model name. All the while the brightness flickers.
Have tried various chargers, I've taken all the cards out but nothing is working
I think it may be a loose connection with the battery (but open to other theories).
If anyone has had this problem, how have you fixed it? Is it worth disassembling and trying to fix it myself (as I'm sure you can tell I don't have a lot of knowledge about this)? Being an eBay purchase is it still under warranty with Samsung? How much would a fix be if it was a loose battery?
Thanks in advance

As far as I am aware items from ebay are not covered under warrenty.
Even with the screen off and nothing happening, leave it on charge for few hours then unplug and try to put it on.
Also have a look into the charger port of the tablet at the bottom to make sure nothing looks bent or out of the ordinary.

shame i always liked samsung over apple.. and bought a product with no support.. apple atleast accepts product bought anywhere in the world and even replaced battery for my frnds iphone 5s when in warranty...
I have not had this issue with my Note, but my Nook did the same thing once. I disconnected the battery for a few minutes and everything reset. No idea if this will help, or if you are adventurous enough to try it.

anyother ideas plz let me know..
but shld i do this quite often?? is this an known error of note???.. do we have this problem when complety drained????
samsung sm-p605 dead not starting, screen flickers
no luck.. i removed the battery from the board, then plugged in back after couple of minutes..
still in same state..
the screen flickers a lot.. is that normal when the note is completely drained..???
It is very bad for the battery to go completely down. I don't let it happen on my devices, so I cannot say if the flicker is normal.
My experience with the Nook was actually a friend's device. He had let it run down, and it was not charging. He left it on the charger for a few days, and it was still not showing a charge. He gave it to me to check out. I disconnected and reconnected the battery. It was probably half an hour or so, because I was interrupted. When I reconnected the battery, the Nook popped on and reported a full battery. Apparently it was charging but not registering anything, and the disconnect allowed things to reset.
If you do not any other ideas, I would suggest leaving on the charger overnight (or longer) and trying the disconnect again. Maybe leave it disconnected longer too.

I have the same exact issue right now! But mine is a refurbished unit. I tried the battery unplug, tried leaving it charging overnight, letting it discharge, flashing new roms, new kernels, etc. Nothing. THe only thing that did work a little bit was changing the kernel. Other than that, even flashing stock ODIN roms wasn't working.
When you charge yours, does it charge up to 75% but won't go any further? And does it take an extremely long time to get there? Because mine does. Reading about other devices that have the same issue, it seems to be the battery. But the other devices were phones. This is a tablet. The battery costs $65 :/

If anyone has had this problem, how have you fixed it? Is it worth disassembling and trying to fix it myself (as I'm sure you can tell I don't have a lot of knowledge about this)? Being an eBay purchase is it still under warranty with Samsung? How much would a fix be if it was a loose battery?
Thanks in advance

I know this is a very late reply and you have probably solved your problem by now, but for future readers with this problem:
I currently have the exact same problem, and just found out what it was. Either my charging cable (official Samsung cable) is faulty. I plugged it into another microUSB cable, and it is now charging again. No more battery symbol that doesn't have the spinning animation or flickering, and now it turns on.

Thanks for this information. Exactly this was the issue. Great!
Charging works and screen stops flickering with Samsung charger if you let it charge in Recovery mode. Mine is still charging as of now, so I don't have any news further yet, but it went from 0% -> 3% after around 30min.
Other than that, I only managed to get charging working with a Motorola's turbo charger.
Hello XDA members. I have a very troublesome issue with my galaxy tab 3 7.0 inch tablet. It will NOT turn on at all, no battery charging, no device power on, no comp recognition, nothing. I have already tried:
Letting it charge overnight (factory charger along with others) with several known working cables
Unplug battery for 5 minutes
Press and hold power, Vol Down, and home for 10 sec, 30 sec, and 1 minute
Press and hold power and vol down for 10,30,60 seconds.
I sent it in for repair and they wouldnt fix it because it's rooted. When I got it back it briefly turned on to the battery charging, but nothing since. I'm thinking there must have been some way they got it on.... All proper drivers are installed on PC and it's never been dropped, water damaged, etc.
Would anyone be able to provide insight as to why and provide a fix?
My 8 inch tab 3 wasn't coming on either a few days back, I got it back on by holding home and the power button for a while. I was about to give upwhen the battery charging image came on. I think I did the same again and it came on normally.

Was that from computer or wall?
From wall, it was about 3/4 charged by then

Still no luck... I can feel the tablet getting hot down at the charge port so I know it's charging, and i know the lcd isn't damaged.
Mine is in the same condition. Anyone know how or why this happens and how to fix it?

Not sure if this will help, but just like with phones, sometimes android tablets just need a battery pull. My kids xo tablet went dead and before I tossed it in the trash I took the housing off and had to clip the + wire since it was soldered to the board. Twisted it back together to check and sure enough the tablet powered on like normal. Ive had to pull the battery on an Sm-t217a and it was a lot easier. They have a removable clip that attaches to the board.

I think it might be the battery itself. Just for giggles I left it plugged in for days and i just checked back on it and the Battery charging screen kept flashing on and off. Won't hold any charge. Probably will just order a new battery and see what happens. I pulled the battery a couple times and nothing happened. Closer inspection found that the tech that looked at it damaged the battery cord (unless it came with the copper on the wiring already exposed...)

You might be right about the battery being dead, although they usually don't just go all at once like that. The charge indicator flashing is odd. The only thing close I've seen is an "x" over the icon when there aren't enough amps (my tab needs 2 amps. 1 amp chargers and some pc usb ports give me the x.
If you have an old cable you can cut, you could try to charge the battery itself to see if it takes a charge (or at least use a multimeter on it to check for voltage). Then you could narrow it down a bit to whether it is the battery or possibly the charge port/hardware..... I saw a bit of exposed wire just before the clip of mine too, made me extra careful pulling the clip up.

I wouldn't even know where to start with the wiring. Multimeter isn't something I have access to, and it seems a little complicated for me to spend time on.
When I say it's flashing, I mean the device powers on to the battery charging screen, then dies, wash rinse repeat. If I go into recovery, same thing. It all happens within a couple seconds, so it's hard to describe.
My dad has one that I can pull the battery from, I might do that. Batteries are like 20 bucks on amazon, so I think I'll test with my Dads and if it works just order a battery and report back here.
similar problem here

My daughters tab 3 7 inch T210 also refuses to start. First time it was fixed by opening the device and disconnecting the battery. Now that doesn't help anymore. If I attach the original charger and measure the voltage when the device has rested for some months I can see that the voltage slowly rises so it seems to do the charging even if there is no sign of charging on the screen. After some hours of charging I measure 3,78V on the battery, after disconnecting the battery.
If I attach the battery and turn on the device I measure 3,76V before I push the start button and 3,74V directly after pushing the button. After about 15s the voltage goes back to 3,76V. Nothing happens on the screen... Tried with different combinations of pushing on-button and volume up, volume down, menu....
So -the best thing would of course be a quick visit to local shop to buy a new device of another brand but for some reason I refuse to give up.
Any advice would be appreciated.
(I Have made no significant modifications but the 4-year old daughter may have contributed in an unknown way )

The better way to test if your tablet can turn on: buy a new battery, under $15 on Ebay since your old battery is dead or completely drained.
Use the new battery to turn on your tablet. If it's on, check the build number of your device after go to About My Device: if it's not end with OB1, the latest firmware which fix charging issue.
It's more likely your build number is MK1 to NI1, the build numbers count by alphabet order. Upgrade the software via Wifi, battery must be at least 25%, otherwise your tablet won't allow you to upgrade. Bring the firmware to the current OB1, your tablet should take charge normally, otherwise the USB charging port is defective or damaged. This micro USB is cheap, around $2, but it need to solder to motherboard to replace the defective one.
This is my older son's N7. A week ago he was playing some dumb game and it froze on him. He, intelligently, immediately restarted the N7 and continued to try to play. This happened about 7 times. The last time he said the screen glitched and it turned off. He then plugged it in and it got very hot according to him, for how long I don't know.
So now I took it apart. The battery was 3.4v-ish and not charging, so I hooked the usb up to it directly and charged up to 4.09v and tried. Still won't turn on (and yes I tried all combination of buttons and lengths). Plugged in the usb, tried again, no luck. But I did notice the qualcomm chip getting very hot very fast.
So what is the next step here? I cannot find a lot of information on this as 99.9% of the time someone just ran their battery completely dead and jumpstarted it back to life. I don't have access to proper reflow equipment so thats off but I'm not against a ghetto heatgun reflow. This thing is long out of warranty so I'm willing to try some invasive tricks on it.
Connect it to a PC and check if a new USB device, id 9008, has been registered. If so, the eMMC chip is gone - more info in the link in my signature. Then in the linked thread please post the maker of your eMMC chip for our statistics.
A bit more info...
I accidentally left the battery plugged in and it drained down to 0.2v , just by sitting there. Hoping it was a battery issue and to kill 2 birds with one stone I ordered a new battery which came in today, plopped it in and... nothing. I tested the battery and it had a charge but it just did the same thing again.
Nothing turns on. The qualcomm chip (or that area in general) heats up, I'm assuming its just sitting there eating the battery. Plugging it in doesn't help (tried 3 chargers, various amps) and it doesn't charge the battery. Last I checked after "charging" a few hours the battery was down to 3.3v , now it's just sitting there unplugged from the motherboard to prevent further damage.
And to answer your question "Connect it to a PC and check if a new USB device, id 9008...", watching "dmesg -w" in linux, not even a blip.
I don't want to keep buying random parts that don't fix the issue and my google-fu failed me in finding any real hardware level testing. So how do I find out what the problem is here?

What do you mean "so I hooked the usb up to it directly and charged up to 4.09v and tried" ? I once soldered a micro usb port directly to the motherboard for charging and in doing so inadvertently created a short between the id wire and a tiny component. Result: CPU heating up quickly and no sign of life. Eliminated it and it was back to normal. If you have done any soldering, check carefully for possible shorts. Some require a magnifying glass (mine was 10X) to be visible. I've not heard many cases of battery suddenly gone dead with this model.

usb wires connected directly to the battery itself, at no point was anything plugged into the motherboard. Also I have done no soldering to the mb so there is nothing to look for in that regards unfortunately.

Please disconnect everything from the motherboard except for the battery. If the chip still gets hot and the battery drains down then the mobo is faulty and you can replace it for around $25 http://www.ebay.com/itm/121637666631
I see no hope of component-level mobo repair because N7-13 has no available circuit diagram.
Finally got around to doing this. Everything disconnected, connected the battery and within about 10 seconds the qualcomm chip is too hot to touch. These chips run hot (or so I've read) so what are the odds it desoldered/fried itself?

Hi everyone,
My phone (almost 2 years old, changed LCD for three times) started to lose a lot of its battery capacity from a month ago, and since yesterday I realized something's wrong with it, as it had some trouble charging the battery. At first, I was using my phone and its battery was around 20%, and then as soon as I connected the charger (genuine fast charge) it turned off and the red LED indicator kept turning on and off and refused to charge. then after a reboot, it started charging again, and then I left it charging at the night and at the morning I realized it only charged to 60% and the red LED didn't turn on at all. And now that all the battery is drowned out it's not charging at all and drawing no current from the charger ([email protected]).
Has anyone had any experience with it before? Is this a battery problem or the USB charging port flex cable which has some ICs on it (example)?
I'd appreciate your answers.
I can't tell from your story that you tried another charger ? I recall a similar charging issue from my HTC One X a few years back.
Replaced the charger and all issues disappeared.

Yes I have, Also seconds before it ran out completely I tried to check if adb works. connected it to my laptop and on the bootloader mode the adb recognized the device but the red LED didn't light up.

That's correct because a device doesn't charge in bootloader mode. Only off state, running OS or Dr TWRP recovery.
If you tried a different charger it can be pretty much only down to hardware, can't give any advice at that level.

Oops, I meant recovery mode.
does the device charge in the stock recovery?

I'm afraid not, only the custom one.
I had almost the same problem with my phone. I sent it to a repair center and acording to their report, the circuit which is responsible for the monitoring of the charging process had a loose connection. Maybe because I dropped the phone a few times. Unfortunatly the circuits of modern phones are all on the same circuit board, so they had to change the whole motherboard of the phone. But now everything works fine.
So I just opened the phone and disconnect/reconnected the battery connector and it eventually started charging with the stock charger, but it charged up to 60% and then stopped. retried the same steps and no luck this time. then I tried charging the battery with an external li-ion charger (I know it's a dangerous task )
this time it charged up to 4.11 volts and then I turned on the phone and again the battery dropped to 60%. so I believe the battery is really dead and needs replacement. I'll update you when I replace it.

Turns out I was wrong, my case was similar to yours. had to waste $9 on a battery to find out
it just fixed by disconnecting/reconnecting the USB connector bottom of the board, but I don't know how the flex cable for the back button got cut so now I have to replace the whole bottom circuit ($17 approx.) :crying:

So I went through the hurdle of replacing my battery and charge port, and the battery transplant went well, went from 70% to 100% battery health (yay!).
The first charge port I purchased (this is all eBay stuff) had a busted Recents button (copper trace in ribbon cable was nicked - when the part was removed from original phone for sure), so I complained and got a replacement; second one works well.
And because all bad things come in threes, the phone developed an echo (on the opposite side of the conversation) which I think I caused by ripping a bit of the mic rubber isolator which points towards the mic hole in the battery cover.
I believe I fixed it (still testing) by glueing some foam padding on the backside of the mic (on the charge port PCB, facing the battery cover).
Long story short, opening up the phone is a b###h, so do multiple repairs together, be careful not to break anything else (easier said....).
Good luck, let us know how it went.
So here's an update, First of all, I'm pretty happy with the battery replacement, It can hold like 10 hours of my usage while the old one could handle up to 6-8 lately, it's unbranded, and I got it from a local phone part store.
Second, the replacement for the charger flex turned out to be pretty good quality, and I've had no problems with it so far. I got it for $11 from AliExpress, but now it's about $10.5. But when I replaced everything and tried to reassemble the phone and tighten the screws it showed up with charging problems again, and I tried disassemble/reassembling the phone and reconnecting the charger flex, and the next time it charged but with no fast charge, so in the next try I also tried cleaning the flex connector with cleaning alcohol, and for the third try it finally started charging with no problems.
So now after like 2 weeks, it's had no problems so far.
