    I've been a jailbreaker for a long time and my jb iPhone always runs perfectly. I love the iPhone specifically because of the jailbreak and how great it is after getting jb tweaks and apps on it. I love it so much that I always convince other iPhone owners I know to let me jb their phones, and once they see the features and advantages that I have on my phone, they usually agree.

    Now I for one have never had any trouble with my jb iPhone. A few weeks or months after I jb a friend's phone, they'll complain that the phone is slow, the animations lag, the apps crash often, and that the phone just overall sucks. Some of them will just end up updating to get rid of the jb and I never get to figure out what the heck went wrong.

    I know it's not the jb's fault, otherwise my phone would be screwed up too. My brother is an avid jb-er and his never screws up either. Sure we both know more about gadgets and that sort of stuff than my friends that I end up jb-ing for, but what I want to know is this:

    What the heck do they do on their phones that causes it to become so laggy? From everything that I've seen, the users are the root cause, not the jailbreak. I just have no idea what exactly they're doing to screw things up...

    They do exactly the same thing that "most" users do on computer, haven't you notice the same complains from people using PCs, after a while the computer takes forever to open a internet browser or even to boot, that is due to the fact that they click "YES" yo everything that pops on the screen, they install every single thing that someone can possible install, Software and Apps like in any other system utilized resources (memory, processor, I/Os, etc), some Apps required to be running all the time, others are running on the background and are called as needed, other only use lot of memory when they are used, the point is that the more you install the less recoures the phone have available for regular operation.

    ^Thanks. That's a good answer, but for most of these users, they don't install any Cydia tweaks or pirated apps. I restore their phones and then do a clean jailbreak, after which they only install apps from the app store. Basically I set up the tweaks they want (that they've seen on my iphone) and then after that, they don't touch Cydia.

    Does weekly reboots or anything like that have anything to do with it?

    Catalina Wine Mixer
    Install the Kill All Background SB settings toggle.
    Have them use it time to time.

    Back when I was using my jailbroken iPhone 4, I could tell (by checking available ram with SBSettings) that when the free RAM dropped below 60Mb the phone would become noticeably laggy. Whenever I noticed the phone was acting funny, apps were stuttering, etc I would check the ram and sure enough available ram was below 100Mb. I had a remove background toggle that I'd need to use regularly to restore available RAM. I'm not sure if this is the case with a non-jailbroken iPhone 4, but I have to say I have not experienced ANY issues with my new 4S, though I do miss some of my old jailbreak tweaks.

    Lots of cydia apps or tweaks tend to require a little extra RAM as compared to App store ones. So that usage of RAM slows down most phones. I would say the 4 and newer don't suffer from slowdowns, but I have never owned a 3GS.

    Winterboard themes definitely slow down a little bit

    Full System themes usually increase some lag.
