hey everyone, i just got my new 13 inch mbp and ive been using it for a couple hours now. it seems to me that it is over heating a little bit but i am not sure. i have attached my istat temps. i am just running safari and mail. my battery is fully charged but i am wondering why my battery level shows only 3.5 hours if i unlpug the charger. is this normal? should i break in my battery somehow? thanks in advance.
