I purchased a 2015- 13", 3.1, 512, 16 off eBay, but apparently it's now lost in the mail, and I will get a full refund.

But it got me thinking about the battery life on the 2015-13" 3.1; can I expect due to the higher I7 processor, that the battery life will most likely be worse than a 2016- 13", 2.4, 512, 16?

My wife has a 2015-13", 3.1 I5, 512, 8, and it gets fairly decent battery life, and I'm just thinking the 3.1 I7 will chew up the battery?

Also, not sure now If I want to get a 2015, when the 2016 is noticeably thinner and lighter?

Can any of you guys shed some light on the battery life on these models?

Thank you

I've always found usage to have a much greater effect than the computer tier within a specific model lineup, to a point where estimating running time is difficult & the different RAM, CPU, and SSD size options have only a limited impact (the exception being the 15-inch models made during the days of IG and DG variants being sold concurrently, where the DG models would get a lot less battery life if performing a task that activated the dGPU.)

Since your wife has a 2015, now might be a good opportunity to try a 2016, as you can do a comprehensive comparison between the two to see which you like more? (and if you like the 2015 more, you could return the 2016 with the 14-day return window and replace it with another 2016?) Best Buy has had some spectacular deals on the 2.0GHz/8GB/256GB Non-touchbar model and the statistics are somewhat misleading as it is quite a capable little machine with good battery life.

To me, the 2015-->2016 15-inch size shrink is more noticeable than with the 13-inch. That's just my personal opinion though.
 
2015. No contest.

Better keyboard.

Ports and slots that you would actually use (USB, HDMI, SDXC slot)
