Battery Cycles

When you keep your notebook plugged in at all times, does the number of the battery cycle increase?
And if the battery life goes down to lets say 50% and you plug in into the outlet to charge, does it count as a battery cycle.
Just curious. Thanks for your time.

If it stays plugged in it will never increase. From my own experience, I believe if it drops below 50% it counts as a cycle. I had it at 50+ a few weeks ago, plugged it in and did not count as a cycle.

From my understanding, a cycle is a trip from 100% to 0%, and it is cumulative. If you run your battery from full to empty at one shot, it is a cycle, if you run it to 50%, recharge, then run it to 50% again, that is a cycle. If you run to 66%, charge, then 66% charge, then 66% and charge, that is a cycle, and so on.
Kwak, if you keep your notebook on AC all of the time, it doesn't "cycle" per se, but it does degrade over time. It is the nature of batteries. What that means is that while you will still have the same number of cycles remaining, a cycle won't be what it used to be, for example if you start out getting 5 hours from a full charge, over time, that will diminish to say, 4 hours. That doesn't change the cycle count, because that is from full to empty, but it does decrease the hour count you have per cycle.

Appreciate the info.
best charging option to extend battery life

I just bought an X60 two days ago. This forum has been a wealth of information.
In the context of preserving battery life (i.e maintaining the ability to have approx 8 hour life with a full charge), what is the best configuration option (within Power manager) to have the best chance of achieving that? Thanks in advance.
