So I've had this MacBook Pro 13" i5 2011 for about two weeks. I'm actually quite impressed on what this laptop can do compare to my Windows7 laptop since I used to be a Windows person but just switched over two weeks ago. 1) Battery Life Omg! I love this! When Apple means 7-8hrs of battery life, they mean 7-8hrs battery life. Unlike my HP Envy Beats, which HP says 7hrs of battery life, only last 2hrs the most and 3.5hrs idle. But this computer is beyond that. Real World Tests Idle - 9hrs+ with screensaver. Surfing with Wi-Fi - 7hrs with 3/4 brightness. Surfing with 3G - 6hrs. Adobe Photoshop - 4hrs. (Photography editing stuff or making logos) Adobe Premiere - 3.5hrs of editing or around 2hrs of pure rendering. Games, World of Warcraft, SCII, TF2, League of Legends - 2-3 hours at medium setting. Music - 5hrs. Videos - 4-5hrs (Backlight keyboard were off) That was just basically my experience of how good the battery life on the MacBook Pro 13" 2011 is.
