I was hesitatant to use my blowdryer to soften the glue behind the battery. So instead, I tried prying it open with the screwdriver (delivered in the tool kit) and punctured it in the proces. STUPID ME. There was smoke and a funny smell. Also the battery heated up. Luckily no flames or bloating up. I freaked out, went outside with the phone and battery still attached. I left it there for the night. The next morning I found this video https://www.youtube.com/watch?v=vkQcmLVu.... It shows you how to remove the daughterboard. This frees up space on the top left corner of the battery. With the spudger you can get under the battery more easily. After this the battery removal was easy. Even without using a blowdryer.
