Hello everyone!
First of all, please excuse me if I placed my question in the wrong spot; I'm new lol.
So, I got my Samsung Galaxy Tab 2 10.1 in December 2012 (for the holidays), and it has always worked perfectly until now.
But this morning, it was dead (which didn't surprise me since when I went to bed, it was at 8%), so when I woke up, it was turned off.
I plugged it in, and it turned on but then shut down after 5 seconds; we see the battery logo and it turns off immediately, and it starts again every time, not even enough time to charge!
And there's no point in trying to turn it on without the charger; it doesn't work at all.
If anyone has a solution, I would really appreciate your help because I don't know what to do, and I don't want to wait until Tuesday to take it to customer service lol.
Thanks in advance!

Here is the translation:
I’ve had this problem for quite a while. The thing is, you shouldn't let the tablet discharge completely. After my daughter did that, now nothing happens except for the battery indicator showing 2 levels and it keeps going like that forever without charging.
So, there's solution 1, which involves holding the power button and the volume up button for 30 seconds while plugging in the tablet, but that works very little for me.
And now I've found, I think, the quick solution: open the tablet (look for how to change the battery on YouTube), then disconnect the battery (black connector in the center), you need to pull it out / wait 5 minutes, reconnect it, and it works right away.

I had the same issue, a blow to the blower and it works again.
Hello, I've been having a problem with my Galaxy Tab 3 charger for a few days...
The issue is that it doesn't charge properly anymore; it's very slow... I plugged it in last night around midnight after using it when it was at 10%, and the next morning at 10 a.m.... it was barely at 15%! That's 5% charging in 10 hours!
Anyway, not normal...
The worst part is when I started turning it on to listen to music (charger still plugged in), the level started dropping again... WHILE CHARGING! I've never seen this before... I feel like the power isn't getting through, or that my tablet is consuming energy abnormally... this has been happening quite a bit lately.
But sometimes, let's say 1/3 of the time, I manage to charge it in less than 30 minutes; I don't know, maybe there's a loose connection...
I'd like to know what you think? Or if anyone has had this problem before, thanks :)))

Hello,
I had a similar issue with a Galaxy Note 10.1, and it was due to the charger.

Hi, it's normal for your Tab 2: when it's too discharged, it just doesn't turn on; and if it's charging, it stays "off" to charge the battery faster, showing you a battery image.
Plug the tablet in for a few minutes, unplug it, start it up, then plug it back in once Android has booted. There you go!

Thanks for the tip. I tried connecting and reconnecting it everywhere without success, I went to your forum. I blew on it as instructed, and it worked.
Thank you for your response, gravgun! But the problem is that when I plug it in, it turns on and off continuously. Normally, I see the battery logo filling up on the screen; now we see the battery, then it turns off, then it starts again!
It may be a charger problem: are you using the original one?
Some chargers don’t provide enough power, and when the tablet turns on to show you the battery, it drains completely (the screen consumes power); whereas the original charger charges the battery quickly enough for it to display the battery for a long enough time and eventually turn off (and stay off).

Rebonjour, avez-vous essayé avec un autre cordon d'alimentation, soit le cordon, soit la batterie ? JC
I lost the original one while on vacation (August), so I've been using a Samsung charger that isn't meant for tablets for 3 months now.
But for the past 3 months, I've never had any charging issues, so why would it be because of that now? Lol.
Thank you for your replies!

As it keeps restarting in a loop, it's problematic: it won't charge in the end. Buying a new charger is an option, but if you have other USB chargers, try them first; maybe one of them will be powerful enough. It's around €12 at FNAC; but what's important is the output power, it can be a charger for another tablet, not necessarily Samsung.
I had this problem before with a "car cigarette lighter" charger that couldn’t provide enough power to charge my tablet. It’s possible that your phone charger could handle more than its rated power for a while but has degraded from overuse in terms of power, which is why it can’t do it now! For a Galaxy Tab 2, you need at least a 10W charger, which should be marked on it as DC 5V - 2A for the output.
Hello everyone, the reason is simple for many of you. It's simply that the battery is too drained; the blinking is because the lighting during connection is draining the charge's juice, which causes it to shut off, basically not enough power even when plugged in.
1. One solution is to use the shortest possible charging cable, which will prevent power losses in the cable.
2. Some car chargers have a bit more power than the charger provided with the tablet, so this might help restart the charging.
3. To avoid this issue, do not let the tablet turn off when it signals that it's drained, plug it in or turn it off.
There you go, I hope I helped you.

Hello, I hope to enlighten you with this
I'm not going to give you false hope, but here’s what I know and what you need to know. Currently, all batteries are lithium-ion or lithium polymer batteries, also known as LI-ION or LIPO. Here it will mainly be the Li-ION. These are batteries that do not discharge if they are not used. However, one element of the batteries generally provides 3.7 volts; these batteries typically consist of 2 elements, thus 7.4 volts, with a lot of milliamp-hours ranging between 5000 and 8000, even up to 10000, or 10 amps, which explains the size of the batteries in the tablet, but they are light. When a battery is charged, it must not exceed 8.2 volts; otherwise, it can catch fire or even explode, and that’s why there are specific chargers to regulate this charging. Generally, Li-ion and Lipo batteries are charged at 1C, meaning once the capacity is charged: a 5000 mah or 5-amp battery should be charged at 5 amps, so normally a battery will be recharged in around one hour, and so on, the charging will always take about an hour. BUT it is also very important that the battery not be discharged below 3.1 volts per element, which here is 6.2 volts. Otherwise, there is a strong chance that charging will no longer be possible and the battery will need to be thrown away, plus a new fire hazard - check out YouTube for the damage that Lipo and Li-Ion batteries can cause if they are not used correctly. When they are defective, they can swell. Charged batteries at rest are slightly above 8 volts. As soon as they are used, the voltage drops to 7.4V and will remain stable for hours of use before slowly dropping to 6V at the end of use (between 6 and 10 hours for the best tablets), which means you need to recharge it right away. NEVER LET IT DROP BELOW 6V, which is the critical non-return limit. Generally, your tablet will give you the autonomy of your batteries. Don’t wait for the critical moment; recharge it. Don’t forget, there can be a fire hazard; the media has already reported issues regarding mobile phones, iPads, and laptops; it has already happened. This is more frequent in modeling where Lipo and Li-ion, and Li-fe batteries are increasingly used.

I will not give you false hope, but from what I know and what you need to know/ Currently, all batteries are lithium-ion or lithium polymer batteries, also known as LI-ION or LIPO. Here it will be predominantly Li-ION. These are batteries that do not discharge if not used. However, one cell of these batteries typically produces 3.7 volts; generally, these batteries consist of 2 cells, thus 7.4 volts with many milliamp hours ranging from 5000 to 8000, or even 10000, in short, 10 amps, which explains the volume of the batteries in the tablet but makes them lightweight. When a battery is charged, it should not exceed 8.2 volts; otherwise, it may catch fire or even explode, which is why there are specific chargers to regulate this charge. Generally, li-ion and lipo batteries charge at 1C, meaning once the charge, a 5000 mAh cell or 5 amps should be charged at 5 amps; thus, a battery is generally recharged in about an hour, and the charging will always last approximately an hour. BUT what is also very important is that the battery should not be discharged below 3.1 volts per cell, which is 6.2 volts here. Otherwise, it is likely that charging will no longer be possible, and the battery will have to be thrown away, plus there’s a new fire hazard - check out YouTube for the damage that lipo and li-ion batteries can cause if not used properly.

You need to wait for the logo to light up and then turn it off, and then keep clicking, and it should work; it did the same thing for me.
To turn it on, wait until the battery is fully charged. After that, wait about 4 minutes, then keep pressing the button until it lights up, but the battery must be fully charged.
In fact, it's just that it charges slowly, so don't worry if you leave it all day or even less, it will restart.
I have to restart for the charging to take place; otherwise, my tablet doesn't detect the charger...
I have the solution.
First of all, in the future, you should avoid waiting for it to completely discharge as this damages the lithium battery.
SOLUTION: you leave your tablet plugged in for 3 days without unplugging it. It will fully recharge.

Hello,
I solved my Galaxy Tab 2 problem, which kept rebooting because it was too discharged. While reading your comments about charger power, I connected it to a stabilized power supply where I can vary the voltage and started with a standard 5V. The tablet was consuming 0.6A but continued to reboot. I raised it to 5.9V, where it was consuming 0.9A. At that point, the reboot happened 2-3 more times (with a bit more time in between), and then it started charging (all night). Now that the battery is recharged, I won’t repeat the "forced" operation, but I will be careful not to let it discharge completely again and will use my normal charger. Thanks for your exchanges that gave me this idea.

I just had exactly the same problem.
I had plugged in the tablet with a charger other than the original one, and I couldn't get it to charge.
I just plugged it in with the original charger, and it works!
The other chargers (like phone chargers for example) are certainly not powerful enough.

Hello! (I've already said it...)
Like everyone else, I have the same problem (oh really, you haven't noticed?). My Samsung Galaxy Tab 2 is a year old and has this charging issue...
I noticed that when it was charging, a red cross appeared. Well, I charge it, but the red cross stays and the battery goes down.
For me too, when it charges, the battery icon moves forward twice and then MAGIC! GONE! And if BY CHANCE it shows 100%, it immediately turns off in 5 minutes!
I also have a few little tips for you that worked very well for me.
Blow into the socket
In the charging hole on the tablet (if that still doesn't work, remove it if you have a cover)
In the charger
On the socket where the charger is connected
Or push on the charger with all your might (if you have any)
For me, when I know my tablet is charging, I hear a dull sound like the sound you hear after someone has shouted in your ears.
To finish off, I’m going to try the cigarette lighter hack otherwise I’ll just buy a new charger.
See you later!

I also have a problem. My tablet used to charge very well. Once it took 3 days to charge and since then it doesn't charge at all. I'm using two different cables, both Samsung. One belongs to my phone, sometimes I use it for my tablet. The other belongs to my tablet, but it's only the cable, not the plug because I lost the original one. None of them work, what should I do, especially since I have my series to watch tomorrow :p?
