Since upgrading to OS 3.0 for the iPhone/iPod Touch, I have noticed some horrendous memory management issues. Obviously, being the end user, I am not fully aware of the technicalities, but I do notice something is quite different. My apps and games HAVE enough memory to run at first, but something is lost as I am playing or doing something in an app.
Sure enough, when I launch iStat to see what changed, the memory was used up by the App I was just running before and I cannot get it back unless I reboot my device or free the memory with the aforementioned app. Now, I fully realize that apps and other functions are supposed to take up resources or memory, but this is ridiculous. The amount of memory used up seems to be greater is used up more quickly during usage of any app, and it does not come back at all.
Not only that, but I cannot end a process completely anymore by holding down the home button.
In contrast, when I used to run OS 2.*, I would start with roughly 48MB of available memory from a clean bootup. After running a game app and exiting to springboard, I would have roughly the same amount of memory STILL available. After launching and exiting native apps like Mail, Safari, and music player (the only "semi background apps" if you will), the amount of memory left was smaller, but not an irritating 3MB like in OS 3.0, compared to ~18-25MB on OS 2.*.
The games I run have unplayable lag and behaviors that ruin the entire experience.This doesn't help me in particular, since I beta test various games for different developers. I cannot be hindered or confused in my testing/reporting with a problem that is clearly the OS' fault rather than the App or its developer.
Please take a look at memory management issues on the older but still very relevant and widely-used devices like the iPod Touch 2G and the iPhone 3G. Not everyone is going to flock to the 3GS and its beefed-up tech specs, which I'm sure might make up or mask the issues I'm reporting.
My tech specs:
-iPod Touch 2G - 8GB
-Running the brand-new 3.0 firmware
-Not jailbroken
-Plenty of storage left (5.5GB now, since I tried and failed to restore from 2.* backup and lost my music and videos)
