i just bought the incase hardshell (which is beautiful and i love it) well ive had my mac for a couple months now and i was getting like 5hours of battery (wifi on bluetooth off only browsing web and such screen brightness way down) well i put on the incase hardshell and now at 86% battery life its giving me a time of only 2:26min. maybe this is due to the incase amping up the internal heat and in turn making the fans spin more? any advice or comments feel free to let me know. im kinda upset im getting alot less battery life.
