So I am a liar? Or I am delusional? Instead of calling BS on something you should be politely asking questions as to how I am getting that....Honestly the posts from people on this forum never cease to amaze me.
Let's do this..Why on EARTH would I lie? What would be a motivation to lie about the performance of my $2200 laptop? I'd be pissed if it didn't meet my needs trust me.
Your experience isn't going to be the same as mine. If you were using airplay that will use more battery life. When I say 9 hours thats light use, open close lids for days before I hook up to the wall again. Maybe yours is a lemon, take it to apple.
