The recurring plague of 'Other Memory'

I also saw that suggestion prior to creating this post and have downloaded that software; however, it doesn't explain how the data designated as 'other memory' on my phone ballooned almost 5GB in size over less than four days of general use. It seems abnormal and having to run software on a daily or weekly basis to keep that issue at bay is unrealistic.

Are there any other thoughts as to why this is occuring other than the breakdown of what that other memory might consist of?

UPDATE: Last night I did another factory reset of the device and restored a previous backup to eleminate the glut of 'other data' -- reducing it from 5.5GB to 900MB -- and now, no less than 12 hours after I performed that reset, the device is once again filled with over 5GB of junk data.

Awesome.

As you can imagine, this device performs like a dream when it is operating at 128MB over capacity. In all seriousness, my next solution to this problem is skipping this POS across the Mississippi River unless someone any helpful advice as to why this problem keeps recurring.

I did. Twice. And the phone managed to fill up with junk data faster than I stuff my own unsorted junk into my closet.

Elcpu's advice was closest to the money in terms of what an Apple rep thought might be the culprit. Their hunch is that there is something corrupt in the backup that is being used after the phone is completely wiped and set up as new. I used a different backup for each time I've wiped and restored the phone, so all parties seem to agree that this is a soft hunch.

Nonetheless, it was recommended that I wipe the phone and reinstall the apps that were previously installed through the App Store to see if the issue with my ballooning 'other memory' still remains. If so, then it's the fun game of whack-a-mole between hardware issue and software issue. Neither would be covered through any warranty, so if I draw the low card with either of those problems I have a sneaking suspicion that the Genius Bar is going to present me with two possible solutions: buy a new phone or go take a long walk off a short pier.

It was already a hassle the first time around getting them to replace my previous iPhone 5S due to a different hardware defect; I can't imagine I would be so lucky a second time.

Let's see what becomes of this. Thanks to everyone for playing so far; it's very much appreciated.
