Battery problem

[Android Central Question]

So my lg's battery occasionally decreases while it's charging until it shuts off & then it charges slower than usual cam be stuck on 0% for 10 min then when it get to like 3% i try to turn it on it starts then the battery decreases so fast that it turns off again & returns to zero. Then the same thing keep happening even if it 4% until suddenly it goes back to normal & charges fast & opens normally so what's wrong?

A bad battery, charge lead, or charge port are possibilities.
