I had this problem too on my 2015 MPB, when Apple went from Magsafe 1 to Magsafe 2, which was (vertically) thinner. The Magsafe 2 easily disconnected when there was even a little vertical torque. I bought a Snuglet, a thin metal shell that inserts into the Magsafe recess on the MBP. It reduces vertical and horizontal clearance between the Magsafe connector halves. In my case, this has completely eliminated unwanted disconnects. Disclaimer: no connection with Snuglet or NewerTech, just have found the product useful as advertised.
