hey all, ive had my macbook pro for the last 5 months and im getting a little worried... ive been reading that when battery is charged u should take it out and leave it in a cool place... true or false? should i just always leave my battery in or take it out when im doing using and rely on AC power? right now using Coconut Battery 2.5.1 5313 mAh which is 96% of my battery left would recalibrating help me? also i noticed that when i take the battery out... itunes will not run at full speed! converting song would go make to like 12-13x while with the battery in it would go up to 22x+ (temperature also jumps by 10 degrees but anyhow) any ideas?! thanks so much!
