I have a samsung galaxy tab 3 and since a couple week the battery goes down fast and even when i'm charging the battery still drown down. I have this tablet since 2013 and is the 2 second time something like this happen.

You're probably letting the battery drop below 50% before charging it, so it's not lasting long. When it's in that condition, most of the current from the charger is going to run the phone, so very little, if any, is left to charge the battery. When it gets bad enough, both the charger and the battery are needed to run the phone, so plugging in the charger just slows down the discharge.
For now, turn thtab off when charging it, and leave it off until it's fully charged, In the future, don't let it drop below 40%, and it should last for years. (My over 10 year old V-551 batteries are still giving me 95% capacity.)
