Battery drain so quickly

Question

Hello,
I have a Samsung Tab Pro android tablet and for several days, the battery is quickly discharged.
- What's the problem
- Do I download a battery booster
- If so, you suggest
Since this problem occurred, I find that when I'm on the Web, we often suggests to me that kind of boost. How can they know, it's amazing!
Big thank you to help me!

Answer 1

Hello.
Your battery is probably the end of life.
And what we suggest you is a scam.
A battery that is the end of life can not be boosted.
Cells of the battery are damaged.

Answer 2

That does not mean anything, a battery loses its ability whatever you may do.
It all depends on the age of the battery, when it was made and how long it has been unloaded.
Even bought a new battery, can not load after a month or even less.
