Macbook Pro 15" Battery Cycle Count

[EugeneY]

Guys,

Lately I found out that my battery cycle count keep going up without doing any full charging. The % of battery life from 100% to 97/96 then went back to 100% by itself & the number of cycle count will be added . Anyone has this problem too?

A charge cycle is any time your battery goes through 100% of a charge. This can be one discharge of 100% to 0% or 100 discharges of 100% to 99%

the problem is the % of battery power will drop from 100% - 97/96%...then it will go up to 100% after days. during this period, i didn't take out my battery or unplug the power adapter. the power always plug-in with it

Yes, I have the same issue. Is this normal?
