I have a MacBook Air A1465 bought it Sep 2012 ish. It has an i7 processor with 8GB RAM. As far as I know the published batterry life is 5 hours. However, I find the battery apalling. The work I do is standard stuff like replying to emails using Outlook, using Dreamweaver a little bit, using applications like MS Word, browsing internet for research and so on. I reckon, I probably get 1.5 hours time on full charge! I cannot understand this. I initially thought maybe it's me. I am doing something that is really resource hungry or power hungry. Today I thought I must get to bottom of this as this machine cost me a lot of money and I should get what I paid for. Anyway, I thought the first test would be to watch a movie or something streaming it from something like BBC iPlayer, and do absolutely nothing else. Not even touch the laptop for the odd typing. Now I haven't finished yet, but I started at 4.30pm with 100% battery life, and now it's 6.52, so let's say it's 7pm, and that's 2.5 hours and I am on 34% left. I don't have enough time to finish the rest of the test as I have to go home. But, I reckon, based on so far I may get another hour at the max. So that's 3.5 hours. That's still nothing close to the 5 hours that is published. Can anyone help or offer advise or pointers. I have a feeling a lot people are going to say what I am already suspecting. It's my i7 processor that's eating into my battery life. Anyway, all advise, opinions, suggestions, welcome. If i don't get descent battery life, is it something I can go and get looked at under warranty???
