i measured the battery, it has 3.7V so it should be enough but the PC doesn't recognize it and it won't turn on normally or in recovery mode, just black screen, no vibrates. Any ideas? I pulled out the battery for some hours as well but it didn't help.

Last night I was using my phone while it was charging, but the battery was being depleted by the apps I was running faster then it was being charged. When it got down to around 3% I decided to call it a night, tapped the power button to turn off the screen, and put my phone on my nightstand so it could charge overnight like I usually do. Shortly after that I heard the phone vibrate where it shut itself off due to the battery dying which I've had happen before while trying to charge my battery when it gets to a very low charge percentage, so I didn't think anything of it and went to sleep.
This morning when I woke up I saw that my phone was stuck on the "Samsung Note II" black bootup screen and tried holding the power button to turn it off. That didn't work so I took out the battery and reinserted it. When I tried to power it back on nothing happened and even though the charger was plugged in there was no red or green charging indicator LED showing.
Since then I've tried taking out the battery and leaving it out while holding the power button for 30 seconds which I read is supposed to clear the RAM in case that is causing an issue. I've also tried connecting my Note 2 to my computer using another charging cable and it still doesn't show as charging or as being connected to my PC. I've had it plugged in for about 3 hours now in case my battery had been completely drained since it may have been stuck on the bootup screen all night long but so far after around 3 hours I'm still not getting any response from my phone.
Now I'm completely at a loss of what to do so I was hoping someone here who had a similar issue could help or if there are any other remedies for troubleshooting I could try go through. I've ordered a replacement battery from amazon which comes with an external charger but I won't be receiving it until Monday. The only other remedy I've found online is removing a capacitor but I'm going to be holding off on doing that until I've exhausted every other option available.
Phone Specs:
Samsung Galaxy Note 2
SGH-T889 (T-Mobile)
Android 4.3 (I think)
Rooted but not running any custom ROMs
Hey folks,
I did not use my tab for several months (it was working before), now when I plug it into the charger (either usb or wall socket) it either hangs in a flashing screen sensation of the Samsung galaxy tab pro screen or at the battery screen while this one is just with a loading icon, it does not really charge.
As soon as I unplug the cable it shuts off. I cannot boot into recovery mode, it just hangs there. I can boot into download mode however and I re-installed root and twrp recovery via Odin, however this did not help.
Any other suggestions please?
Appreciate the help.
Plug it into the wall. Leave it plugged into the charger. Hold the power button down for up to 2 minutes. See how it goes!
No change, just keeps rebooting.

When you didn't use the tablet for those several months did you keep it running or did you use the power off option, if you left it running then it probably shut it-self down when battery got low, then the extra time left probably completely depleted the battery causing irreversible damage to the battery (lithium-ion batterys aren't made to deplete to 0 volts it will ruin them), the proper way to store a battery device is to fully charge it then power off the device and it should store for up to a year fine.
sometimes you can give the battery a boost, or maybe the samsung charger blew out, first try another 2+ amp charger and a new cable.
or you can even try your pc usb port connect it for about 10-15 minutes (sometimes the low 500mA current is good to revive completely dead batteries though keep the screen off), see if you can get any voltage back into the battery and if it starts holding a charge, then switch to a proper charger.
if the battery is under 3v the tablet is designed to shut off to protect the battery so if the voltage is less then that it might take some tinkering to get the voltage above that threshold to keep the tablet running.

I'd guess it was left off without powering it down.
When I plug it into the PC via USB or into a power socket I just see the 'Samsung Galaxy Tab Pro SM-T320' log and it is flashing continuously.
RMA? I can get into download mode, but how does that help me? Knox warranty void shows 0x1 - it's voided, correct?
Anyone?
hello
your battery is hs
look here to change it: "https://www.newpower99.com/"
when you leave back your tablet use these: "repair battery life" & "L speed"
regard
thanks
can anyone vouch for this shop? I'll order a battery there and try to repair it myself.
that worked, easy installation and extended battery life
Hi guys! i'm occuring in a big problem, i was wondering if anyone of you had this experience with this or others phones, two days ago my htc 10 was totally without battery and died, so i put it on charge, but nothing happens, no led on, if i try to power on, no signs of life, unable to make it boot, even after hours of charge, i noticed that the phone anche the charger were cold, instead of hot like it should.... but after hours, even without led indicator on, i trying to recover it, with surprise, it was hot, i tryed to power on, no signs, i tryed combination of power button and volume buttons and it booted into dowload mode, and after a millisecond it re-died, and booted normally with 65% battery. BTW from that point the phone is unable to charge if i plug the cable into it, nothing happens, but if i put the cable, when is off, it charges even after boot, i tryed to recalibrate battery but nothing happens.... any suggestion?
So I am using my tab pro with CM13 for almost a year then suddenly, while playing vainglory. It turned off automatically. I thought it just ran out of battery so I decided to charge it. After waiting for a couple of minutes, it didn't charge, it just boot looping, I tried to enter recovery mode but it won't. I can't pass. Only Download mode works. I tried to connect it into pc to flash another recovery in Odin but I can't, it just reboots again. Any suggestion? I also did removed the battery for 24hrs. and placed it again hoping that it will work... changed usb cables, but nothing happened.... help .... Thanks!
This literally happened to me yesterday on lineage 14.1. I was watching Plex, and the tablet crashed, powered off and was stuck on the logo screen when I tried to power it back up.
I hard powered off the tablet and plugged it in to charge overnight. I flipped the screen cover over the tablet, but I think it entered a bootloop after plugging it into the charger and the battery drained. (didn't charge while connected to charger)
For some reason the tablet refused to charge and would enter a bootloop again.
I tried to enter recovery, and it would show the twrp screen before rebooting.
I was able to get into download mode though.
To fix this issue I connected the tablet into the wall charger and held the tablet power button for 2 mins as suggested in this thread.

Thanks for the help and thread suggestion. Before I jump to conclusions, i just want to add that I also tried to use the tablet without its battery but plugged in into wall charger. I am getting same results. So my problem wasn't the battery, right? I did press the power button more than 2mins. While trying to charge using my wall charger, still the same
Darn, in that case it sounds like your issue could be related to something else.
I've been trying to figure out why my Galaxy Note 4 is not getting any power, but I just can't figure this out. I've tried letting it charge with a known good cable, booting it into recovery mode, and replacing the battery. I can't get it to turn on.
I checked the battery with a multimeter and it shows around 3.4 V. When I plug the phone in to a wall charger and test the battery contacts, I get about 4.8 V, so I know the phone is getting power (or at least the battery).
But unlike another Note 4 I have, this one won't show the notification light or anything. It doesn't show when I plug it into my computer, either.
What can I do to get it to turn on?
