iPhone OS 3.0 - Atrocious Memory Management
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)

Inappropriate?I have exactly the same problem with the addition that the app I'm developping was nice under 2.2 and now is horribly slow !!!
-
Inappropriate?Ditto. My app running on OS 2.2.1, 1st gen. iPod Touch takes no more than 1.2 MB of memory, but it keeps on eating memory with the same settings running on OS 3.0, iPhone 3GS. The memory usage crept to more than 4 MB after 5.5 minutes, and eventually exceeded 9 MB after 17 minutes when I finally got tired and quit.
I’m disappointed

Inappropriate?DX-Chain,
I have gotten quite frustrated with this too. When I run the exact same application under OS 2.2.1 and 3.0, the former's memory usage is stable and the latter's climbs until, after a while, a reboot is required.
I guess we all have to wait for the forthcoming patch which, hopefully, will focus primarily on such issues.
Thank you for your post.

Inappropriate?I'm sure you've probably figured it out by now, but if not, to force quit in 3.0
you now hold the power button until the slider screen shows, release, then hold the home button for ~six seconds.
That still doesn't help the memory issues though. I am getting pretty frustrated with the new OS- too many bugs! Hopefully the rumored soon-to-come-update fixes all that... -
