my MBP is mainly a desktop PC when im at uni so always plugged in and on sleep.

according to cocunut battery, the battery capcity was shipped at 102% and now has a maximum charge of 96%. is this normal?

i did calibrate it when i bought it. :/
 
Yes, it's normal that your battery health will fluctuate up and down over time. It's not good to keep your MBP plugged in all the time, as your battery needs exercise to stay healthy. This should answer most, if not all, of your battery questions:
 
Yeah it's normal don't worry about it. Just make sure every 2 or 3 days you unplug and use the laptop on battery mode.
