As the topic title says... My MBP is just 21 weeks old and it has 111 battery loadcycles with 96% battery capacity (see the attachment). I have calibrated the battery three times so far, but I'm still not sure weather I should keep the MBP on the power outlet all the time, or use the battery and let it drain down every time.
Got a tip for us?

Yes, that's what I'm trying to figure out!?! I do use it at least 12 hours a day, but it's still too much, isn't it?
Your usage is fine. Be sure to read the Battery FAQ that simsaladimbamba posted. It really will answer your questions.
My 13" Pro is just a few days over 1 year old and shows 66 charge cycles. I normally run it on battery when the cable is either inconvenient or when I only plan to have it on a few minutes and on the charger when I plan to have it on for any length of time. And every ~month run it on battery until it complains and shuts down on its own.
My early 2008 macbook pro:
Battery-Loadcycles: 176
Age of your Mac: 42 Month
Current Battery Capacity: 78%
I use it every day, but most of the time I move from one charger to the next. About once a week I run off batteries for a longer time, e.g. when I work in a cafe. I don't calibrate my battery (costs too much time), nor do I perform any other procedures that are supposed to improve battery life. I'm quite happy how it keeps working through the years.
I guess 111 load cycles is reasonable if you run from full to discharged every day. Since the batteries are supposed to work through 1000+ cycles, I don't think it will be a problem. But I also don't think it helps improving the battery if you drain it unnecessarily.

I would not limit my use of the macbook by what might be good or bad for the battery. The current batteries are designed to go through 1000 load cycles without loosing too much capacity (see the FAQ linked above). So, worst case is that in 3-4 years you have worn down the battery and might need to replace it, although 80% of the original capacity is still perfectly portable.
Well, that is the explanation I was looking for. I did unnecessarily unplugged my MBP as soon as the battery showed 100% full. That is the main reason why MBP has 111 loadcycles. However, thanks to your explanation I will have it plugged all the time and drain it once a week, from now on.
Thank you!
I'm at 112 in 25 weeks... it all depends on what you use it for. I use it almost constantly, and didn't keep it plugged in all the time when i first started using it...
I am a student so I am constantly using my laptop during class and throughout the day moving from different buildings and such. A lost of my assignments are actually on the computer (mainly on the internet via an online homework thing provided by the University) and MATLAB programming, so I'll often charge my laptop every night, then take notes on it the next day and do homework on it. With that being said, I don't use my charger unless I get close to running out of battery.
My trusty old whitebook has had a good 56 months... 384 charge cycles.
Current capacity: 4640mAh
Design capacity: 5020 mAh

Hmm...
Calibrated once a year around Christmas.

Of course, if you don't calibrate more frequently than that, you have no idea how accurate that reading is.
If you read the Battery FAQ in the 2nd post of this thread, all your battery questions should be answered. Newer MBPs with built-in batteries come pre-calibrated and do not require regular calibration. That Battery FAQ was also posted in the other thread you started on batteries. I highly recommend you read it.
90 cycles, had it since late August.
I use it every day, and when I'm not using it, someone else in my house is using it.
