After some research it makes sense why the battery is not removable on the razr. They are using a lithium polymer battery instead of an ion battery. It is used in all the apple products and probably a lot of slim tablets. It is a gel pack battery instead of solid like we have known in all our other droid phones. Hence the stainless frame and kevlar back. The batteries swell a bit more and can get warmer that the ions. However they can be molded much thinner. Apparently they are a bit more volatile than ions as well and can explode easier. That would make sense why they don't want customers tampering with them. I had not seen this mentioned and wanted to throw it out here. Tapatalk and Toshiba Thrive.
