Thanks for the tutorial. An excellent presentation on how to carefully access and replace the battery in a Surface Pro 4. I was able to complete this procedure without breaking the display glass and successfully replaced the battery in my old Surface Pro 4 with an iFixIt battery. I used iFixIt tools available from the iFixIt site. The only suggestion I would make would be to use a dental pick to remove the EMI shields from the Surface Pro. The supplied tweezers in the iFixIt tool kit was not strong enough and the tips bent. Also recommend carefully cleaning the glass surface of the display below the camera openings to ensure the cameras have a clear view once all the adhesive is removed, before the display is reattached to the case.
