Pretty silly question, of course the i5 will have better battery life than the i7.
How is it silly? I have heard that the i7 got BETTER battery life than the i5 in the SP3.
I'm not sure how something more powerful, with more transistors and much beefier GPU would use less power. Barring a device design error.
Surface Pro 3 i5 vs i7 - Is the Upgrade Worth the Money? • Love My Surface
That is an engineering question... And not so easy. Remeber the i7 is still a 2 core part with HT
Read about why the HasWell i7u bear i5 in battery life. That being said I agree - the new iris i7 seems to have more on the die. We shall see in benchmarks
I've been very disappointed the battery usage on my new sp4. I'm using a reading app (Freda) and have the unit settings a the darker option and the battery saver on with the reading app light setting at about 50% and can only read for 3 to 4 hours before the unit needs to be recharged. I talked with tech support and the decided to send me a new unit but this one is no better on battery drain than the first. I was really hoping for a 9 to 10 charge at the very least. This actual reading time from 100% to 8% battery scale. using the sp4 i5
Battery life varies with both usage and what you have running in the background. I'm still early in my testing but, once I disabled all cloud synchronization programs that I had running (OneDrive, Cubby), I'm up to 8'ish hours of projected battery life (21% over 105 minutes), up from about 6.5 hours when all I do is use Chrome with Adblock. I think most people have a lot of things installed that run in the background that they're not aware of or are browsing sites with a lot of ads that chew up a lot of CPU cycles. You can find my battery life tracking here:

Most USB battery packs are 5V. Only the Surface 3 (non-Pro) can be charged with that. The SP3 and SP4 requires a 12V battery pack. Same with the SP2 as well.
Id recommend getting the 8 GB SP2. Not only because its your ideal size (size matters, a lot), but its also a lot cheaper by now, although you may need to buy used. The second candidate would be the 8 GB SP4, but you lose the Power Cover, size preference, and cost advantage.
If you prefer Windows 8.1, the SP4 is also pretty much a no-go.
Here's the comparison between all 3 models of the SP4 Face Off: Microsoft Surface Pro 4 Core i7 vs. Surface Pro 4 Core i5 vs. Surface Pro 4 Core m3
True but if you're web browsing and that's what it is telling you, and you continue to do that for the next hour, the time remaining should be right. But again, depends on web pages with ads or how often you stop and read, etc.
