I recently got a Samsung Galaxy Tab E for testing purposes. Apparently, it was laying around for quite some time. It wasn't surprising that it wouldn't turn on. But after charging it for 2 hours, I suspect that the battery is in a deep discharge (or maybe the micro USB port is broken). What should I do?

FYI:
Ysterday I dedected a strange behaviour of battery charging:
While on Tuesday, when I received my SGS II it was charging quickly with the original EU-Charger while setting up my SGS II and then driving it to it´s (still unfound ) limits it loaded pretty fast up to 100 %.
Day 2 and 3 no prob at all.
Yesterday while filling up my 32gb SD card with music and videos over KIES air (SGS II charging with original charger) battery started to degrade while in action.
Ther I switched it off, let it load switched off for 2-3 hozrs and when starting up it showed only 94%.
Did not worry about this.
But last night I left it switched on and charging, showing that it is charging, but this morning found it stuck at 84% batt cap.
Switched it off, charged it for 1 hour, switched on and still on 84%.
Now I plugged in my travel charge adapter (hama USB Charger 5V 800mA), SGS II switched on in idle and within 2 hours it was full at 100%,
I suspect the original charger to be faulty .....................
For the first time after 2 weeks, this morning battery was %95 and I sat it on the keyboard dock and it was not charging. I tried the same old cable with and without USB extended directly on Tab.. no charge. I switched to my old 7" Tab and it began to charge, then again to 10.1 and it started charging but the battery level showed %65. It had suddenly dropped from %95 to %65 during this time. I was getting very good battery life. In standby mode I got more than 3 days. Should I be concerned?
Yesterday my galaxy s2 battery drained to 0% within a couple of hours and when i got home it would not charge or turn on. No power, boot, recovery or download. It was dead. I have seen the battery charging icon come on for a second a couple of times but it is not charging.
Today i got my Galaxy S (S1) battery and aligned 3 out of the 4 pins with the battery on an angle, then pushed the battery to hold contact. With the usb cable plugged in, All of a sudden the charging battery icon came up!! you must keep holding it but.
ill use this to make titanium backup and cwm nandroid backup, while i send back my galaxy s2 to get repaired.
report back if this works for you!
i believe the problem is either the battery or the usb charging circuit.
i gave the S2 battery some juice with my old galaxy S1 usb battery charger. now it is in the S2 and charging slowly via AC, however battery temperature is reading 66 degrees celcius.. i changed the charging current back to default values (650,450,450)
Worked for me too!
My phone didn't charge overnight -- seemed dead as a doornail.
Stuck in the battery from my old Galaxy S and booted just like yours!
Don't know whether it is the battery or something else yet, but thanks!

Hello guys, I have a Samsung Galaxy Note 4 (N910C) , I reset it a week ago and I am starting to have issues. The phone will not charger more than 70% (fast charger connected) even after 2 hours of uninterrupted charging. When I turn off the phone and charge it still shows 70% but when I remove the battery and plug it in again then the phone shows 100% charged and I am good for another day until this problems repeats. Please help if this is a hardware issue or an issue with software or battery calibration and suggest any methods to resolve it.
try battery re calibration
My tab has some problem with battery drain/charging. This happened just over night.
Even if the tab is powered off, the battery is drained within a one or two hours.
First I noticed that when charging, one spot on the back cover is within minutes over 46 degrees hot and charging is very slow (20% after 5 hours). The spot stays hot after removing the charging cable and the tab is powered off, until the battery totally drained.
After removing the cover, the circuit (see picture) is going hot immediatelly after connencting the charging cable, even if the battery is disconnected.
Maybe is this circuit damaged? Any opinion?
