Well, the battery 'saying' it is that charged doesn't mean it actually is. If the battery is needing replacement, which is pretty normal, it will charge less and less. So saying it is at say 100% might actually only allow for use of 30% of the battery itself.

To resolve that, you would need to replace the battery.
