good ram amount?

pjnolen

the iphones when shipped have the following ram amounts.

iphone 2g/3g = 128
iphone 3gs = 256
iphone 4 = 512

How much ram does the operating system use up?
What's left over for our applications?
What's a good target amount for any 1 game/scene to use to stay in a 'green' zone?

From my experience a 2g/3g will crash with much over 60MB. a 3GS at about 120ish and an iphone 4? .... not managed to crash it with a GS game yet.

not sure why i'm using so much. Under Memory usage I have:

Images: 153 KB
Sounds: 0 KB
Game Engine: 3.5 MB
Other: 38 MB
Total: 41.7 MB

I have 5 images totaling 153k but Other is 38 megs?
What is other? attributes? actors? There's only 5 actors in this scene, it's the start screen, with a background and 4 buttons, sound, difficulty, medals, and start.

I haven't added in the animation, or the music, how can i possibly be using up all the ram already?

when I press my 'difficulty' button, it takes me to my screen with just 3 images, nothing else. The images total 400k, but my memory useage jumps to 67 megs.

it's just a black background, with 1 'back' button, and 3 difficulty options, which are the small images. touching them only changes 1 attribute and that's all.
