Some of the music on my iPhone 4G 32Gig started skipping intermittently when I play it on the phone. These are mp3 files synch'd to the iPhone through iTunes from my Windows 7 laptop.

I have filled it to 28G.

The same song played back again at a later time does not skip but another one might.

What is going on here?

What do I do about this?

  • @Nathan this happens when I am playing it on my iPhone

  • Just to clarify, you mean the music stutters, but keeps playing on the same song? Can you tell me if your phone is jailbroken?

  • @IntuitionHQ It sounds like when a CD skips. My phone is not jailbroken.

Definitely sounds like its fragmentation-related.

I found a few sources, take with a grain-of-salt but it seems to back up the hypothesis.

My earlier post:

Edit: Thank you for the info.

Some additional info could help with this:

  • iPhone release (orig, 3g, 3gs etc...)
  • codec of audio: (mp3? apple lossless? aiff?...)

Without the additional info, my first hypothesis would be that its a memory issue. You might try killing some other apps (yes, I know they shouldn't be running, but there may be some related processing happening in the background.)

To take it to another extreme for testing purposes, do you have video clips you could try? If so, test them out and come back if there's any useful information gathered.

One last thing, I doubt its related but, how full is the storage on the iPhone?

  • Playing video does not skip. The same song again has not skipped either.

  • Interesting, about how far (in seconds) does it get before it starts skipping?

  • Both times it happened, it was toward the end of the song. Then I replayed the song.. no skipping!

  • The song length long or short? (a thought that maybe its somehow being played back faster than it can be read into memory.)
