Battery issue LoadCycle count increases without charging , MacBook Pro Retina 2012?

Question

Hi
i have the feeling that i have a battery issue.
It looks like that  the battery cells are in one region defekt.
Once i cross about 30% last charge it starts draining very fast within 10-15 Minutes the MacBook switches off.
In order to proove this i have written a small script in order monitor the battery and some other counters.
And here is realized anothe interesting topic.
The Load Cycle Count can increase even if you dont charge !!
Below you see that the LoadCycle Count increased from 373 to 374 even if i didnt charge.
Any ideas on that. Or does anyone have the same issue ?

tesme33,
have you tried resetting your MacBook Pro’s System Management Controller, to see if that affects its energy consumption?
When I run
ioreg -n AppleSmartBattery -r | grep -i CycleCount
on my MacBook Pro, I get two different output lines. You might want to adjust that part of the CYCLECOUNT assignment to have
ioreg -n AppleSmartBattery -r | grep '"CycleCount"'
instead, to ensure that that returns only the intended single line.
