Battery not fully charged (it shows 100%)

Ever since I upgraded from ubuntu 12.04 to 14.04 I've been noticing that the battery does not last as much as it used to. The bar indicator shows that it is fully charged but I ran tlp-stat and I got this:

+++ Battery Status
/sys/class/power_supply/BAT1/manufacturer = MSI
/sys/class/power_supply/BAT1/model_name = BTY-M6D
/sys/class/power_supply/BAT1/cycle_count = (not supported)
/sys/class/power_supply/BAT1/charge_full_design = 7800 [mAh]
/sys/class/power_supply/BAT1/charge_full = 2466 [mAh]
/sys/class/power_supply/BAT1/charge_now = 2387 [mAh]

So it means that the battery is not fully charged even though it says 96%. It also says charged rather than keep charging it until it reaches 100%.

Is there any way to solve this issue? Or it might be really a hardware issue with the battery rather than a software issue with the upgrade?

Thank you.
