iPhone slow - how to free up RAM?

I've noticed lately my iPhone's been pretty slow loading most apps (even the simple Google app), sometimes 5 seconds or more loading time, the keyboard takes a few seconds to respond, and it's not uncommon for an app to just give up and return to the home screen when I do certain things.

I know apps don't run in the background (as opposed to a computer) so I have no idea where this slowness can be coming from - what factors into it? Does it matter how many apps are installed/how much free space there is?

I have iStat pro on my ipod touch and it has a "Free Memory" function that does a pretty good job of opening up almost half of my iPod's RAM. It does lot's of other neat stuff too and I can use it to monitor temps and memory usage on my laptop if I'm in a game and don't want to exit just to check my GPU temp. It runs like five or six bucks in the app store but it's definitely worth it.

You should power your iPhone off once a day. Try that, see if it helps.

I'm not jailbroken. Just for information, I'm using a 3G (not 3GS) with OS 3.0.

Thanks for the app recommendations! I'll look into them. I'd appreciate any general info on what effects the iPhone's response times, though.

Don't some of the "free memory" apps only erase stuff to make space for music and apps? I never use them so hopefully someone else can chime in. All I know is that iStat ONLY clears up RAM, I don't know of any others that do.

No, but there is a new free one called Memory Sweep:

I absolutely love Memory Info from Recession Apps. With their newest update, I can just click the icon and it starts freeing memory right away, done within a few seconds, then I can hit the home button and go from there.
Just my 2cents

I think that you are confused.

Memory is the same thing as RAM. It is not where music and apps are stored. They are stored on the iPhone's flash drive.

I know the difference but I thought that the "Free memory" apps cleared up space on the flash memory and not the RAM.

Nope, they clear the RAM. At least Memory Sweep does.

Memory Sweep will appear on you iPhone as 'Scan'.

I like FreeMemory. And they have now updated it for the 32 GB 3GS.

Free Memory/Scan

I would reccommend Free Memory Lite too. Not a bad little bit of kit considering it lists the background processes hidden to those of us in Apple's little 'jail'.

I'm using SBSettings to free memory(jailbroken)

Is there any advantages to the ones in the app store vs SBSettings processes...

Is it normal to start with about 40MB free then drop to 20 when opening safari...sometimes it drops to 10....it seems super sluggish loading lately....

Another vote for iStat.

Did your iPhone start to slow down right after the 3.0 update? Mine did. (3G Black 16GB.) I got tired of restarting it several times a day.

I bought iStat and it has been working for me.

hai guys here is the solution to enhance the ram performance on your iphone4,it's really an awesome application called "MEMORY BOOSTER HD" costing just 0.99$ being in itune application store which makes your phone memory free helping to multi tasking operation without restarting your device.whenever your ram is lower than 30mb, just terminate the backround application&open memory booster application & click the start button,with in 10seconds,the ram would increase up to 350mb,the normal level,if you have any problems, just contact me via mail,[ststharan@gmail.com]

Looking at the App Store, I found this app called "MEMORY 100%" by Cocopok and it woks pretty good for cleaning memory on an iPhone 4. You will see the difference.
