Hi. After doing some research looking for a laptop that I can use for work, I've decided to go with the Dell XPS 13 because of the great reviews and price.

I want to use the laptop mainly for development using the latest version of Visual Studio, so although at first I thought of getting the cheaper version with an i5, I started to debate if I should instead get the a little more expensive i7 version in order to speed up those compiling times.

However, to my surprise I found that Microsoft Store gives the i5 an up to 11 hours battery life (http://www.microsoftstore.com/store/msusa/en_US/pdp/Del...) and the i7 an up to 6 hours batter life (http://www.microsoftstore.com/store/msusa/en_US/pdp/Del...).

Although I'd like to have a little more power, that seems an extreme difference. I plan on travelling a lot and taking my laptop with me, so battery life is also very important.

I just wanted to confirm that this indeed makes sense, and that it's not simply a mistake made by whoever put the specifications in Microsoft Store.

Thanks.

It is probably the idle time. But there will be a difference in battery life though between the cpu's
