METHOD FOR A DATA BACKUP UNIT TO INTELLIGENTLY CHARGE A MOBILE DEVICE

After a data backup unit connects to a mobile device, an App executed on the mobile device will create a user profile block in the memory unit of the data backup unit, help set up charging preferences and backup preferences in the profile block, and create a backup folder to store backup files from the mobile device. The App estimates a charging time required to charge the battery, a backup time required to complete the data backup and an available time interval, then the App sums up the charging time and the backup time to get a required time interval. Then, the App compares the required time interval and the available time interval to decide whether to perform both the backup task and the charging task or to perform just the charging task.
