Nearly half of the total user-accessible storage being free is apparently not enough as it is the root cause of a tablet's woeful responsiveness.
I'll begin this writeup with an update on a recent one, in which I discussed freeing up flash memory storage space in order to improve overall smartphone performance, as measured by parameters such as application launch and multitasking speeds. After deleting non-essential maps from the copies of the NAVIGON North America GSP application running on my AT&T and Verizon iPhone 4s handsets, therefore getting them to 1.2 and 1.5 GBytes of free storage respectively, I remembered that I'd also purchased and installed several "extras" features for the program. One, Panorama View 3D, was particularly notable in its demands, gobbling up 729.2 MB of storage space.
It's unfortunately not possible to selectively uninstall "extras;" I needed to delete the entire program, then re-download and reinstall its base configuration. However, the end result was worth the effort; I now have 2.1 GBytes of free storage on my AT&T iPhone 4s, with 1.8 GBytes free on its Verizon counterpart. And my earlier prediction that "were I able to further increase the amount of free storage memory, I suspect they'd be faster (and longer so) still" has proven correct. Application launches and task-switches still sometimes take longer than I wished was the case (and than used to be the case with iOS 7), but the experience is now generally tolerable.
Unfortunately, my experimentation wasn't as successful with my first-generation (2012) Google Nexus 7, a situation I've "solved" by wiping it to a factory-default state, gifting it to my niece, and replacing it with a second-generation (2013 "FHD") Nexus 7 successor.
