PVRTC compression increasing the file sizes of PNG

For iPhone game development, I switched from PNG format to PVRTC format for the sake of performance. But PVRTC compression is creating files that are much bigger than the PNG files.. So a PNG of 140 KB (1024x1024) gets bloated to 512 KB or more in the PVRTC format.. I read somewhere that a PNG file of 50KB got compressed to some 10KB and...

color depth bits?

(Quick version: jump to paragraph next to the last one - the one beginning with "But") I was happy in my ignorance believing that PVRTC images were 4 or 2 bits per channel. That sounded plausible.

PVRTexTool, Is it effective for large amounts of small textures?

I have an iPad app that uses a ton(500+) of small(128x128, 256x256 or less) textures with alpha. At any given time there are probably 30~90 of these textures loaded with around 30 displayed. The app has slightly slow load times when I use PNG files so i am trying to improve them by using pvr textures. I want to keep as much quality as...
