It may take a considerable amount of time to back up your iPhone with iTunes, which is changing according to the amount of files you own and the number of times you've synced your device. Many users had this on-going issue that, sometimes, backups are taking an hour or even iPhone backup taking forever and they usually couldn't manage to get over with that problem. Therefore, regardless of whether you have run into this trouble or not, we are going to introduce a few solutions for you to try and speed up iTunes backup on iPhone 7/7 Plus/6s/6/SE/5s/5.
Removing those ancient apps can help to solve this problem by speeding up your iPhone backups, since there will be less data to transfer at each backup. So if you aren't using an old app anymore, get rid of it, there's not much reason to keep it around on your iPhone.
Your iPhone backups might be slowed down if you have a large camera roll. The reason is that the iPhone backup process will duplicate all your photos regardless of whether or not there having been any changes made to them. So you should backup your iPhone photos and then delete the originals from the iPhone regularly.
In addition to photos, media files tend to increase the time it takes to backup a phone to your iTunes library. If you have videos or music on your iPhone that you no longer need, deleting these files will speed up the backup time. OS X Daily found that removing video files from the iPhone was the most effective in speeding up the backup process. iTunes video rentals can be fairly large in size and take a while to sync, so after viewing these, remove the files from your device permanently.
Allowing too much time to pass between backups can really increase the amount of time necessary to backup your iPhone. Try to keep regular backups of your iPhone, just get in a habit of making one full backup once or twice a month. I have noticed a direct correlation between the lengths of time a backup takes to complete and how often I perform full backups: the longer time that passes between backups the slower the backup will be.
Now try these solutions to speed up iPhone backup. If your next iTunes backup takes a long time, don't forget to try iCareFone, which can help you backup quickly and easily.
