I do not recommend this procedure. The battery is very flimsy, can be easily deformed, and often tightly glued down. Any slight deformation can cause it to short and explode. Would be safer to get a different phone (not Sony).
Once the battery has been disconnected from PCB and you cant pry the battery out easily then it is glued in position instead of double sided tape you will need to very gently warm it up with a hair drier (not on the highest setting and not a heat gun as its too hot which will cause the battery to explode) and gently pry it out. I do recommend Sony mobiles, used them for years and are very stable, Never had a battery explode from over charging like on all Samsung mobiles. Unfortunately I learned the hard way and used too much force removing the battery that I damaged the connector on the ribbon cable for the screen. Ordered a 2nd hand L2 to replace the cable. Also its a Torx 5 needed not a torx 4 as stated at the top of the website.
