Do I need to stack charge?

I'd like to use my PlayBook, but without having to keep it connected to a power source.

Though it indicates that the battery is at 100%, within minutes it decreases quickly, down to 22% within a minute or so.

If it's continuously plugged in, I can use as normal.

Tried using the included charger and the rapid charger.
It's been like this for a couple of years, but haven't had the time or mind set to work on it. Does this sound like a job for stack charge?

Mine drains fairly quickly too but not that fast, and I have used different BB chargers to charge it. I just figured it was the age of the battery seeing I have had the PB from the time it was released.

As an aside, here is hoping you and your family are doing well.

Never heard of stack charging. But I do use my blackberry playbook from time to time.
Really wish I could help. :\
