What can I do to extend battery life?

How can I manually deploy the TPK file to the device?

The TPK file is the executable that the Unity build system creates for you. You can use Build and Run to build the TPK, transfer to the device, and then launch it for you. If you do not want to use Build and Run from the editor, you can use build to make the TPK only. To transfer the TPK to the device you can use a command line tool called sdb. This tool can be found in the tools folder in your Tizen SDK installation. Use a command line such as:

./tizen-sdk/tools/sdb install YourUnitySignedApp.tpk
