TEsting Battery Life on the Surface Pro 4 Core M

11/4/2015

5 Comments

 
I've received a lot of requests to do one of my loved battery time lapse videos, so this one is for all of you! I set the brightness to 25%, put on a continuous video, and recorded my Surface Pro 4 (Core M model) until the battery died. As you can see in the video, the battery lasted a whopping 11 hours and 22 minutes! Be sure the watch the video below!

In reality, multitasking, web browsing, and keeping the screen brighter than 25% will cause the Surface to work a bit harder and you probably won't get over 11 hours of battery life. That said, the Core M model uses so little energy and generates so little heat that it's actually FANLESS. That's right, there's no fan in the Core M model, unlike the Core i5 and Core i7 mode. But what you gain in battery life, you lose in performance - though it's a worthy trade-off if you don't need the extra speed.
I also tested the Power Cover, which did wonders to boost the battery life in my Surface Pro 3 video, but was bummed when I found it that the Power Cover does not work with the Surface Pro 4! Surprisingly, the Power Cover contacts exist in the Surface Pro 4 (They are in the Surface Pro 3 but not the Surface 3). This leads me to believe that perhaps a Surface Pro 4 Power Cover may be coming in the future. I'm a huge fan of the Power Cover and the extra battery life it brings. I was in battery heaven when I used it with my Surface 2 RT, getting over 20 hours of battery life!! (See the video here)

Overall, the Surface Pro 4 has solid battery life in my experience with it so far. I'd love to hear your battery life experiences so far - please leave a comment below!

Hi Sean,
Can you please check the driver date of your battery? or if you can update it? More and more are reporting that they could update it from a 2006 version to a 2013 one and after that the battery life improved.

Yes, I just applied this fix and it appears to be working great! See my test results here: http://imgur.com/G5fl3su

Great. That is a significant improvement.
Thanks for the fast reply and feedback.

(I thought that it will improve also while it is being used and not just when it is in sleep, but maybe I'm asking too much :) )

Hi Sean,

I'm about to upgrade from surface pro 3 to 4.

Please tell if you have been satisfied with the entry level core m3?

Many thanks
