Hi Vaio-Fz11s,
we have been informed that the battery meter can apparently sometimes report incorrect information when displaying the battery charge level.
However if the battery states it is only 85% charged the actual charge is 100% and there will be no difference in battery life between a unit that displays 100% battery charge and yours that states 85% charged..
If you are at all concerned then I suggest you contact Sony Vaio support, you can do this either by phone or via e-Support, use the following link to find the contact details: Sony Vaio Support
