I have bought a 128G iXpand recently and want to backup the 48 G photo/video in my iphone 5.
There are about 5800 items in the camera roll.
My iPhone battery can only support backup about 2000 items.
When the battery is nearly used out, I stop the sync process and quite the app, recharge my iphone.
After my iphone had power again, I open the iXpand app and try continue the Sync process.
Then, the Apps in “Preparing Syncing…”, after 1-2 minutes, the App quit suddenly.
What can I do?
