Hi my tablet is crashing every time the battery is lower than 80% (it turns off immediately) end keeps crashing every time i restart it and begin using it after 2 or 3 seconds and the battery drains every restart .Is it surely a battery problem or it could be caused by anything else?

Probably you have a cracked battery connector, common problem of Samsung tablet. Re solder will fix this problem, you can verify by removing the back cover, apply directly pressure on the black battery connector and turn your tablet on; if it works, problem solved, just find someone or a repair shop to help you to re solder the battery connector.
Don't forget to fix the white battery connector too, it's also the source of problem

Unplugged and re-plugged battery helps to solve problem, then you may need to do this little fix of the white battery connector. I had one battery which didn't take charge, after this simple fix , it works normal again.

You need a thin knife and magnified glass to do this fix, push the opening as close as possible.

Hi Guys,
Got a problem here. This will be my 2nd Note2 after sending it back to Samsung couple of months ago. It was charging this morning and tonight after a long day of work, I decided to play some game on it. Noticed that the battery is on 15% I decided to charge it. After 30mins I checked the status of the battery and to my amaze it was not charging! I tried 3 different cables, 2 different chargers, and none of them works. Tried my cables and chargers to a different phones and it does work. I connected my note 2 to my laptop, and it does not recognized it. Tried to charge it while it is turned off, I can see a battery icon, but it does not show the charging battery icon. It will disappear in a few seconds. Please see image below:

It's a rooted phone. Tried to clean the charging port. I even opened it without damaging the warranty sticker, and I can definitely say that there's no moist inside. But just to be sure, I blow it using a hair dryer with the temp off. But with no luck. I used to experienced this a few weeks ago where went back charging after a few minutes. But this time it's worst, it's been an hour and a half and still it is not charging. I can't do a full wipe yet since the battery got 9% left on it.
I know that if it will really not charge, to resolve it..it's either I send it back again to Samsung, replace the board myself (hope it works), or buy an external battery charger. Unless there's more that I can do to fix it.

I did but to my amazed after leaving it alone the whole night, It went back charging again. Yes I am glad that it's working again but I am worried it might happen again sooner or later. I have read some threads with the same issue and with the same outcome, I really want to know what's behind this.
So if its under warranty unroot and monitor

The tablet gets very hot at the back of the tablet, near Samsung logo, in a specific area.
Does anyone else have this overhearing problem in this specific area?

Overheating may cause by cracked battery connector, common problem in Samsung tablets.
Re solder the black battery connector will fix this problem.
This connector was re soldered by adding more solders to its six pins to fix quick discharge, overheating, burning smell.

How's your battery life? If the battery is starting to lose capacity the internal voltage regulator will work overtime to compensate. My tablet was doing just this and was almost too hot to hold and I was getting horrible battery life (45 minutes screen on time kind of horrible).
One new battery install later and the heating problems is gone and I'm back to 8 hour SOT.

If running an extension cord max of 10A with a load more than 10A, it will get hot even melted by overheat.
The same thing happens to cracked battery connector, the main board will get hot when its solder joints partly connected to battery.

Hello,
I have several Tab Pro's that are all having the same problem. I have charged the devices to 100% then when it sits for a few days it will not turn back on. I have plugged it back in and it show 0%.
This is what i have done to try and find the issue...
1. I have reset all cables
2.Tried different batteries (USED)
3.Re-Rom with ODIN and Factory reset
4.Checked the pins on battery terminal for bad solder contacts
5.Waiting on new batteries
Now the interesting part. I charged 2 devices to 100% then disconnected the battery from the Logic board so I could check to see if the battery is discharging on its own. After 3 days I reconnected the battery terminal and tried to turn it back on. They will not power on, then I plug in the charger and battery icon shows up with 100% and then I'm able to turn it back on. Any ideas what the issues with these are I have about 8 of them all doing the same thing?
Thank you,
The battery doesn't discharge on its own so fast like your description. I have a Tab Pro 12.2 , which is off almost 3 months, when turns on it still keep the charge at 99%

The problem is from the cracked battery connector, it will cause intermittent connection. Trust me, remove the back cover, use your hand to press directly on the battery connector while turning it on, it might work depending how bad the crack is. All you need is resolder the battery connector.

I have tried to resolder a few of them and they still do not turn on or they discharge the battery. I have a few that I charged the batteries up to 100% and disconnected them from the battery terminal on the logic board over the weekend. They all still do not turn on, then I connect the charger and the battery icon shows up with 100% then I can turn it on. I have tried what you said and pushed on the terminals on all of the ones I have and not one will turn on. I'm starting to think there is a issue with the power management chip on the board. Has anyone tried to replace any of these?
I have had issues with SM-t/p900 12.2 pros that had the issues you are talking about, not charging, flickering screen, and the terminals needed to be resoldered. I could actually push the pins up and down. The SM-t520 pins are solid and do not move.
My battery gauge got stuck at 100% Tab will die without ever going down at all. Anyone have any ideas? I have rebooted several times, wiped the cache, and did a factory reset.
It is not rooted 8.4 inch Verizon LTE.

The battery shows 100% but immediate shuts down indicates your battery connector's joints have cracked, not connected to mainboard.
The same thing if your battery disconnected from mainboard, plug in your charger, press HOME button, it will briefly show the green 100% batttery icon

Bring it to a repair shop or anyone who knows how to solder, to resolder the battery connector.
It takes no more than 5 minutes

You can try to power on while pressing directly on the black battery connector to help closing the cracks.
Another case: the white battery connector with 6 wires has loose connection, try to disconnect and reconnect the battery may help.

Thanks but the battery works, just the gauge stays at 100% until it dies. If I charge it unplugged the gauge will start at 100% then slowly goes down then goes back up. But when I turn it on it stays at 100% the whole time.

The battery capacity goes up and down is an obvious sign of cracked battery connector. It will cause intermittent connection.
You need to read this threat to understand which is causing the problem, not only this model but other Samsung tablets as well.

Hello everyone. My question is related to the pin connector and battery life:
3 months ago, i though it was moment for battery replacement of my S 8.4, but in the process i broke the 6-pin connector placed in the board. So, I tried to deal with it and charge the new battery once, with the connector slightly detached and badly soldered. It went bad since wasn't charging normally, i screwed badly the connector so had to replace it.
I ordered the new connector with an official tech support. Connector took few weeks to arrive (i live in Chile). I did the microsoldering with a lot of troubles, and after watching tutorials and buying soldering stuff, practicing and studying the possible troubles i could face, i finally did it (see the pic). Anyway I'm skeptic about what i just did XD (btw i used soldering paste for smd, really cool stuff)

Now it's charging, after 3 hrs it went from 20 - 90%. My questions are 2:
1) considering that many experts point out that lithium battery's first charge is extremely important for technical reasons (SEI forming on first charge cycle; non full charge leads to fading over time), should i replace my battery soon, if i stored at 20% for 2 months?
2) how do i know if i soldered correctly the connector, should i consider the time it takes (normally charging cycle was around 3 hrs 30 from 0 - 100%)?
Thanks!
need help with soldering
Hi buddy , have a similar needs as yours, except in my case i did not break the connector , it broke by itself after a few months , guess a bad solder at the samsung factory itself .
So now coming to the point , i ordered a new connector and was thinking to solder it myself as service center was charging a hefty price for a small repair . Could you please guide me as to what all is required to do it properly .
li-ion battery`s dont need a forming charge on first charge.
Dont run the battery too low as the battery can fail, I don't go below 20% (I use a charge level alarm)
I don't charge above 80%(I use a charge alarm) , I have charged to 100% only 7 time in 28months(only after flashing or upgrades to calibrate the battery gauge)
i have used my T800 every day and no problems so far.
John.
Im also having the same problem...
The connector pin just came off from the motherboard...In my case..im so afraid to do the microsoldering,however i tried “reflow solder” heat up the connecter while sticking it on the motherboard for few seconds...then let it cool...yes it was succesfully connected..but its not strong enough...it just came off again when i grabbed the tablet to put on its backcover...The main reason why im scared to do the microsoldering is what if i accidently damaged other components in the motherboard...is there any other way to solve this issue other replacing the motherboard...
