Sounds like a normal behaviour for a battery that has already some years of 
operation. There is basically nothing that you can do, except trying to 
'reformat' the battery: Discharging it down to 3-5%, then recahrging to 
100%, and repeat this cycle some 2-3 times. (If you still have the Windoze 
installed, I think the Lenovo tools offer this option)

It *may* bring back some capacity, but in the long run you will not come 
around buying a new battery.

I noticed the same on some older TP (A30), the latest one (Z60m) is still 
quite OK ...after 4.5 years
