Hi, I'm trying to understand why my mbp tb 13" battery drains so damn fast. So I got coconut battery to understand what's going on. It shows me 4359 mAh max capacity. On average, if I do almost nothing, just have my standard range of apps open like "mail, messages, things and itunes (no music playing) and some apps in the menu, like dropbox, istat menues, 1password, and one safari window open, I have a drain at around 650 mAh. At Display 50% that is. that leaves me at approximately 6 hours of battery life, if you assume that it sometimes spikes a little because of an occasional youtube video or something more intense. It might easily go up to 792 mAh. 5 Hours is more like my actual experience with this machine at MAX. What kind of values are you guys getting? Maybe I can identify some battery killer, if these values are out of line, or maybe this points to some software issue at hand? Cause I dont see ANY way to get to 10 hours of battery life. I dont know what appls to close...I dont feel this is anything out of the ordinary, but the battery can never reach the promised 10 hours like this!
