I bought a new MacBook Pro 5 days ago and so far, the battery has only lasted ~2.5 hours when I have used it without a power source. For instance, right now the battery is at 93% capacity and I only have 1:52 remaining. For a while, I thought it might be because I was using the "normal" option, but even after switching it to the "Better Battery Life" option, it is still only at 1:52. System Info tells me that I have only gone through 5 cycles. On Apple's website, I have read that the battery should last up to 5 hours. I didn't expect it to be completely accurate, but this seems ridiculous to me. Is there something I am doing wrong? Right now, I am not running any power-intensive applications. In fact, all I am running is wireless internet and Firefox (sorry Safari fans). I didn't do any configuration of the battery, but the manual that came with the laptop said I didn't need to. Do I need to get my battery replaced, and if so, how do I do this? I absolutely need to have my computer with me for the next few weeks, so I cannot send it anywhere. Can I take it to the nearby Apple Store and get this resolved? Also, I don't want a replacement laptop because configuring this one for the work I do (installing programs, etc.) took a very long time. I don't have the time to go through that process again (I will be very busy for the next few weeks). If anybody has any advice, I would really appreciate it. Other than this issue, my MacBook Pro has been fantastic. I absolutely love it. P.S. I bought the lower-end model. A 15" screen, 2.4 GHz, 5400 rpm HDD, etc. Thanks!
