Hey guys, About a month ago, I purchased a brand new Mid 2014 rMBP. It's a 15 inch with 512 GB storage on it. The official specs page on Apple's website claims up to 8 hours of wireless web browsing. I've been doing almost nothing but web browsing since I got it, however, I'm not getting anywhere near 8 hours of wireless battery life off of the charger. Not even close to 6. What could be the reason? Now, to shed a little bit more light into my set up: My brightness is at about 70% at all times (but set to automatically adjust) Keyboard backlight is off unless I choose to turn it on manually (almost never) I'm also usually connected to a Thunderbolt display (and use my Macbook as a "second" monitor on the side (since I choose not to leave it on the charger 24/7). Could this explain my dramatic reduction in battery life? Does docking to the Thunderbolt display hog battery? Is 70% brightness too high to expect even 5, or 6 hours of casual web browsing battery life? Help me understand! Thanks.
