Something is Eating up my Internal Memory

[emmanskie88]

I don't know if someone have already brought this problem.

Here's the thing.. I just Downgraded my Samsung Galaxy Note 10.1 from Jellybean to Ice Cream Sandwich again.
The reason is.. on JellyBean my Note took 1 and a half day to be fully charged and battery draining really fast.

my Problem now on ICS is something is really eating up my note's internal memory, it even comes to a point that
my usable 11.75GB of memory is full and I don't know what system or apps is doing it. I even reinstall the firmware
and do a factory reset.

I only have a few apps you can see it on this image:

and this is my indication that my internal memory is increasing overtime without doing anything like browsing or gaming.
Before i go to work it is just 3GB now it is 5GB+

I am having hte same issue after updating my S2. A few apps needed to be updated, but couldnt cause I have no space. Which I found weird. I haven't done a factory reset yet. I feel as if when I was installing the new OS, something must've gone wrong, so I gotta try to reinstall it again.
