  1. Wow, I just followed all of these steps along with restoring my iphone & now I have 9.5 GB of free space! My phone was so clogged up it wouldn’t even let me take photos, and Siri would practically freeze my phone if I tried to call anyone with it. Now everything is working fast and I have all this new free space. Thanks!

  2. I can’t clear any cache when i used phoneclean. The system found nothing but my phone space is reducing. Why? Btw i’m using ios 8.3

    • In 8.3 I noticed you cannot clear e-mail cache. I deleted my email account which used to clear all cache before 8.3 . Does not work now. I deleted my email account, and there is 117MB of e-mail space listed under “usage.” This is a big fat bug.

    • I’m having the same issue… I’ve been using PhoneClean for over a year now and it’s always cleared 800MB+ for me, but this past month it hasn’t been finding ANYTHING – although I know for a fact that I have a bunch of documents/data that will clear a big chunk of space on my phone if deleted. So strange.

  3. I’ve had always faced difficulty in the case of third party apps. May be I can try out these steps next time and save some time. Cheers.

  4. I always use Safewiper iOS Data Eraser app to clean large junk files from my iPhone every time, when I feel my device run slowly, I used Safewipe to clean the junk files, I love it!

  5. I have connected my iPhone to system and copied and pasted some data manually without using ITunes but now I am not able to see the files I pasted there but the internal memory is being used nearly 5 GB I am not able to use , mine is IPhone 6Splus 16 GB so I got only 11 GB as free space in that lot of spaces gone, can I know how to delete those files I manually pasted.

  6. Hi I have iPhone 6s 16gb iOS 9.2 if i delete all and i restore the iOS from iTunes
