The battery quality is not good. Either the battery is not well charged and the charging time is too long, or it has not been used up frequently, or it has been unplugged before it is full, hehe. This is how my original MOTO battery was charged. I took a bubble and put it on the table. I can turn it by hand several times.

Although the lithium battery has no memory effect, I suggest you use it up before charging to fully activate the lithium element in the battery, so I think the battery can last for a long time.
