When you buy a new phone you can easily migrate all your settings and your trained WiFi locations by taking advantage of the Backup/Restore feature.

If both the old and the new phone have Android 2.2 or above:

• on the old phone, open JuiceDefender
• swipe to the About tab and scroll down to the Backup/Restore section
• tap on Backup then Confirm
• wait 10 minutes or so to make sure the backup file is stored in the cloud
• on the new phone, after you’ve set up your Google account, install JuiceDefender and Plus or Ultimate if you purchased them
• open JuiceDefender, swipe to the About tab, scroll down to the Backup/Restore section
• JuiceDefender should have retrieved the backup file from the cloud and say something like “Last backup 5 minutes ago”; if not, read below
• tap on Restore then Confirm.

If the cloud-based backup is not available, or not functioning properly, you can manually copy the file /sdcard/Download/JuiceDefender.backup to the new phone (obviously if you just take out the SD card from the old phone and place it into the new phone you don’t need to do this, unless your physical SD card folder is different – some phones with internal storage mount it to /external_sd for example), then proceed with the restore on the new phone.
