This worked for me! I could not pull free any of the battery adhesives despite my best efforts and care -consistent pull but not too hard - the adhesive stretched but would not budge and in each case it eventually tore. However, using the workaround was fine - some pure alcohol drops and gentle lifting from the speaker end worked it free. Thinking back, it was cold where I was working this, and I wonder if the adhesives could have moved easier if I had applied heat to the back of the phone underneath the battery for a while, sat it on an iOpener for a while...maybe?
