When playing with Link2Sd note that below each application you have:
- APK size
- Dex size
- Lib size
- Application Data size
- Cache size
When moving to SD card (APP2SD) only APK file goes to SD card, Dex and Lib remains in you phone memory. If you move those apps with Link2SD all files will be move to the external SD card increasing your phone memory a lot. Application Data size remains always in the phone memory so you may consider deleting this, just hold your finger and choose option to clear application data.
The last resort is converting some applications to a system apps which will move them to the separate partition releasing some memory.
