Battery won't charge/Weird battery problems

Hey guys, I recently had a problem with my screen turning on and off on it's own but finally it stopped. But now I'm having even worse problems.
Basically what is happening is that my phone won't charge. Last night it was at 60% and I put it in the charger. I woke up in the middle of the night and I checked my phone and it was fully charged, so I went back to bed. When I woke up in the morning to take my phone it was only at 49%, so I plugged it back in and it charged to 54% before I had to go. I barely used to phone all day to conserve on power since I didn't really have much left. So, it's at 40% battery when I get back home and I plug it into to charge. I left it for an hour or two and went to go check on it. It didn't charge at all. In fact all the stats were saying that it was discharging. So I unplugged it from the back side (where the charger is in the wall) and the lightning bolt was still in the top corner. I freaked out and unplugged it from the usb port and it stopped, when I plugged it back into the usb (without power from the power outlet) it showed that it was still charging which was really weird. I tried everything such as taking out the battery and putting back in. I even tried to use a different usb cable to charge it with no success. But still everything says it's discharging.
I have no idea what to do? Could this a sign that the battery is failing, should I buy a new one? Does anybody have any idea of what might be happening? I've been looking everywhere but I haven't found any solutions

It's probably input voltage dropping caused by USB cable. Try another cable and see.

Well the problem stopped for a few days but now it back again, I plug it in to charge and it just doesn't charge, it recognizes that it's plugged in but it just won't charge.

I'm now attempting to charge it with a different cable again to see if it works. If it doesn't could this be a sign of a battery issue? Because if it is I can buy one tomorrow.

I'm starting to think it might be the charging point, hypothetically if I were to send it to Samsung for repairs, how much would they charge for replacing the charging port. Or would it easier to replace it myself if I were to buy one off ebay? How difficult is it to replace the charging port?

Battery recalibration

I thought I'd share this in case anyone else has/is experiencing battery problems. Mine was somewhat strange:
When powered on, my One would charge using pretty much any standard USB charging cable and wall charger, however, if the battery drained all the way and the phone powered down, it would ONLY work with a cheapo Chinese wall plug and power-only micro USB cable. Weird, right? If I hadn't had this random cable lying around (I can't remember what it's from,) my phone would have been effectively bricked.
SO....after searching the web to no avail, I finally called Verizon who did say it was covered by warranty, but they wanted to check with HTC first, which is where I learned this little trick:
To recalibrate your battery to a specific charger (or in general) do the following:
1) With phone on and plugged in to the charger (kinda a problem if your phone won't charge...I suppose you could try it with it off as well...) Hold ALL the physical buttons down for 3 minutes (Power+Vol up/down) The phone will cycle a bunch of times (you'll see only the HTC logo.)
2) After the 3 minutes is up, leave the phone plugged in and don't mess with it for 10 minutes (I'd say leave it whether it is on or off at the end of the 3 minutes, if it's off turn it back on and let it sit for another 10 minutes or so, that's what I did.)
That's it! Apparently this calibrates the battery to the charger you are using & it did the trick for me. I can now let my phone die & plug it in using any charger I have & it will actually charge. I'm not sure if this will help with any other battery problems people may have, but it might be worth a try if you've exhausted your alternatives.

Really odd Charging situation

I got great battery life yesterday (better than usual I'd say....had about 50% left after about 3 hours of screen on and 13 hours off the charger, so I let it sit off the charger over night. Not something I normally do. When I woke up I used it for a bit and got to about 21 hours off charger and 4 hours of screen on....the important thing is this:
when I plugged it back in, it started carging like normal I left the room for a bit, came back.....and it was up a couple percent, but said it was no longer charging. I've reseated the charging cable a couple of times, to no avail. When the phone is on, it won't respond to the cable at all. If I turn the phone off, and plug in the cable, it comes on, acts like it knows it's charging. but keeps bouncing from the Samsung screen to the battery charging screen (no animation though) and a quick vibrate. It seems like if I leave it on, and leave it with the charger in, it'll charge, but it's not reflected in the battery %. if I reboot, it'll go up some, but not as quickly as it should have.
I've been fighting this all day and am finally up to the high 70s. also, if the phone is on, and I have the cable plugged in, but pull the battery, the phone will stay on via the power cable for about 3 seconds. Have been using DartStalker 6 with the Compulsion Kernel. I had an old version of that kernel so I updated to 10 with no change. Obviously wiped cache and dalvik for that....
it seems really weird that it kinda knows it's being charged, but.....seems
IDK....any ideas? suggestions? oh, also if I plug the cable into my laptop, the laptop doesn't see the device.
also, stock cable and charger block. have tried different regular USB cables and chargers....specifically whatever my wife is using to charge (successfully) her HTC One Mini.

just had more weird stuff happen. got home threw the phone on the charger, hooray! it shows that it's charging! after letting it sit for a bit I check it....it's lost juice. UGH!
Went to T-Mobile today. New phone should be here in 2 days. Oh well.....

Note 8 completely died

I am hoping someone may be able to help me here. My Galaxy Note has been working perfectly for me without issue since I have gotten. Yesterday I charged it to 100%, and took it off the charger as I didn't need to charge it anymore, and wasn't planning on using it until today. Well today I go to turn it on, and I get nothing. No lights, no screen flashes, no sounds. When I plug it into the charger I get nothing as well. I have tried to remove the battery, and put it back and that doesn't work. I've tried all the different power and volume/home combinations I can think of but nothing has worked. I was wondering if anyone had any experience with this, or any advice of what the problem may even be.

Try to plug in for 15 minutes and see what happens.
I got a scare with no way to turn it on, but once I plugged it with external battery for few minutes and it came back up charging.

I've tried with the stock Samsung charger and I've gotten nothing. I've been charging it since this morning.

If you have something to read DC than could pull the battery again and see if it has a charge. Just my first thought.

Have you tried a new charger or cable? Both may be defective.

HELP! Can't charge Galaxy Tab S 10.5

I've been having all kinds of trouble getting my tablet to charge. It's acting really weird. Over the last couple of days, I will turn the tablet on and it will say 80% charged (after being plugged in all night). Then, with it still plugged in, it will drain down to 15% in about 30 minutes. Why would it drain so fast (if at all?) when it's plugged in? It's also been taking hours for it to charge once it hits that 15% and I don't use it.
At first, I discovered my charging cable was to blame. I'd plug it in, but the tablet wouldn't detect it was connected unless I pulled on the wires just right for them to make contact. Apparently there was a broken wire inside the plug of the cable. So I replaced it with a new cable. Everything seemed to be working good then, and was actually getting proper charges again. Now though, it doesn't seem to want to work.
I was using the tablet yesterday to check my email. It had been plugged in all day and not being used. It said it was at 100%. After about 10 minutes though, the tablet shut off saying "battery low". When I try to turn it back on, I get the battery indicator showing it's at 0%. So I left it plugged in the rest of the day and over night. I just went to turn it on about an hour ago, and it's still sitting at 0%!
I thought maybe the cable was bad again, so I found another charger and tried that. It does the same thing the other cable does.. It stays off until I plug in the cable. Then, as soon as it's in, the tablet "wakes up" and displays the battery indicator. Like, it detects a power source has been plugged in. But no matter what I do, and how long I keep it plugged in, it stays at 0%. I can force the tablet to turn on by holding the power button. It goes through the boot animation prior to loading the screen. Then, in about 5 seconds, it turns itself off again.
I don't think the battery is truly at 0%. If it were, how would it be able to boot up without even a cable plugged in? I really don't know what to do now. I've rooted it, so I can't send it in to Samsung for repair. I don't even think the warranty would still be good at this point anyway. The tablet is at least 3 years old (based on when I joined this site looking for root help). And I think it was 2-3 years older than that before I bought it. Is there anything I can do?

I can't wait anymore. So frustrating to own something that's worked great then all of a sudden decide to no want to even power on anymore. I've spent all day trying to get it to charge with other cables. I've tried chargers, I've tried just straight cables. Plugging into the wall, plugging into the computer, plugging into the USB port in the car. Nothing works. So I hopped over to Amazon to just order a new tablet. I can afford it, not big deal there. But then I saw a ribbon cable used to replace the USB port on the tablet. Maybe the port is bad? Lots of "highly recommended" reviews. I went ahead and ordered one. It was less than $7. If it doesn't work, I still have the money to go forward with buying a new tablet. If it does, money saved! I went ahead and bought the "customers also buy" kit, with a replacement battery (just in case it's not the port), and a set of tools. If the cable is all I need, I'll have a spare battery. If the battery is all I need, I'll have a spare ribbon. If it still doesn't work, I'll go back to my original plan.
Just kinda bummed this is where I have to go now. Why would it suddenly just stop altogether like that? Is it because I keep it plugged in 95% of the time? Should I keep it unplugged till it's drained then charge it and unplug it again right away? I used to have to do that with an old cell phone. This is my first tablet so I dunno. If I end up needing to replace the whole thing, it'd be nice to know from experienced users what the best way to do it is, and what, if anything, I can do to prevent it happening again.

I'd suspect the battery is kaput.
It's not a good idea to keep the battery on permanent charge, there's no need. Let it cycle normally.

Well, all told this was an educating experience. I got the battery first. It came about 40% charged. Once it was installed I used TWRP to create a system backup and downloaded it to my computer. Then I left it plugged in overnight. The next day it was down to 30%. So the "charging" indicator on the screen was just a bunch of lies. I got the replacement charging port a day later and installed it. I didn't do anything else with the tablet, just left it turned off and the charging cable plugged in. It said it was charging, but again, after about 12 hours of charging overnight, the following morning it was down to 18%. So I'm returning both the battery and the port. They may still be working fine, and the problem is elsewhere in the tablet. I accidentally broke the little metal connectors over the power button (it's a contact sensor, and the connectors sit on top and complete the circuit when the button is pressed) when I took the back off to replace the parts. I also cracked my screen, although I think it's just the protector I put on it. I'm not sure what else to try at this point. The tablet is essentially a paperweight now. I can turn it on and watch the battery slowly drain to 0%, but I'll never get any more use out of it. So I decided to do a system wipe prior to putting it away for some future project to try and rescue it. Now it's stuck with the "Teamwin" screen flashing at me. I give up. I looked at Amazon to see if I could just buy another one, but they don't have any "new" left. They're all refurbished or "slightly used" from 3rd parties. I looked at other tablets, and bought a new Samsung Galaxy Tab S5E. It looks like it has the best reviews and marks. The only issue would be the wifi, but it seems to be a hit or miss with people. Some people say it's a problem, others say they don't even have a problem. So.. <shrug> I'll see how it works for me.
