The main changes are the updating (from Nokia) of Samsung's PC suite to the same codebase as the current Nokia PC Suite 7.
Note: If the installer fails or seems to be taking a long time (more than 5 minutes without doing anything) then uninstall ALL Samsung PC Suite components, including the CDMA drivers; then restart your computer and re-run the new installer.
The battery is not as long as possible, no protection circuit of the battery is full of that should stop charging, or battery for heating or overheat impact performance
