So just like the title says. I'm only getting 2-3 hours of battery power on my new MBP. I calibrated my battery yesterday, to see if that fixed the issue, but it didn't. All I'm using is Safari and iTunes. The battery percentage seems to be dropping 1% every 2 minutes. Anything I can do to fix this. My 14 days return policy will be up this Sunday, should I try to exchange it b4 the 14 days is up??
