You're not supposed to overload your phone like that with so many apps as the phone isn't intended to be that full. You're causing your own issues there.
Best thing you can do for your phone is remove some of those apps so that your phone isn't struggling, and be sure to leave some room for those irritating updates that Google likes to force on us.
If the memory is there I feel like it's meant to be used. lol. But personally, I filled up the entire internal memory the first day I had it...
I'm looking at my app list by size right now, everything possible to be moved to the SD moved, of course:
(Used to have Google+ installed but it literally took 14 MB after moving to SD)
Maps - 11.05 MB
Facebook - 8.14 MB
Market - 7.89 MB
Music (Beta) - 7.68 MB
Browser - 6.41 MB
Docs - 5.01 MB
Voice Search - 4.81 MB
SoundHound - 4.23 MB
Youtube - 3.73 MB
Adobe Reader - 3.70 MB
Gmail - 3.60 MB
Angry Birds - 3.04 MB
A lot of those are built-in or system apps... And they're taking so much space. I only have like 150 or so apps installed. And that's after finding alternative applications that take up less space on the internal drive. I keep having to remove apps that are important to me just to get updates. If I had known this phone had such space issues I would have rooted the first day I got it.
I'm still looking in to rooting my phone, since I know if I had the extra space I'd easily fill 10x as much space as is available on the stock phone. I still don't know much about it, though, and I'm trying to make sure I can find a rooting method that keeps my Android 2.2.1 rom, phone number, settings, apps, etc...
Anyways, I'm a gamer and I always love to get the most out of my hardware. So I've got a lot of processor intensive and memory heavy 3D games as well. But I feel like 30 games shouldn't be enough to fill up the major portion of the internal storage that it does

I would easily download 100 more games in a day if the space was available.
But I feel like I've gotten to the point where I'm repeating myself XD... On a side note, if anyone knows how to root the V while keeping my settings/apps/2.2.1 version, PM me and let me know.
