In BatteryTipLoader, two threads may access BatteryDatabaseManager simultaneously. In this case thread A may close the database thread B holds, then settings will crash. In this cl, we make the BatteryDatabaseManager as singleton and synchronize all the database related method. Then it shouldn't have the crash anymore.
