Wondering what the average usage battery life truly is. Not just simple light web browsing. But multiple applications open, and actually using the laptop. Brightness around 50-60%. Im not going to state actual programs but just a decent load, not full load but not light. What is the battery life (if just ranges that fine to) that you get? And with one note, I see you can get office 365 on a mac now, but how is it compared to full windows version? I use it for my everything. Note taking, excel, all that. Start this off, I have always had the surface pro since launch. My first one croaked and I immediately went with the new surface pro 3. While its soo much better than the first, I was expecting better battery life. Alas, with my usage battery is (while still a tad better) a mix of 4-5 hours. My use is Onenote, outlook, kindle desktop app, calculator, and a few web pages every hour. Surface pro that equals about 4.5 hours. Just web browsing or light stuff, I can manage 5-5.5 hours. Problem is, either at work or school, I get there at 8am, and by noon im chasing for a charger. Since ive had the surface pro for about 2 years now, ive really become accustomed to it (being touchscreen, and pen support). I've been taught some awesome things on the MacBook at best buy. And last week have tried to only use the surface as a laptop. Trying to narrow down if I 'need' the pen, or since Ive always had it just used the pen. So far, laptop only has worked fine. And I do have a galaxy note 10.1 with pen support for when I 'need' a pen for like ladder logic, circuit drawing, ect. But I just wanted to see if the pen was a sometimes needed or a needed. So the pen is nice, but not 'needed' in every day. So if the battery life is vastly better, and full fledge one note windows vs apple is the same, id probably start to sway MacBook.
