Does a JailBreak Slow the IPhone Down?

[Boxheed]

Hey now! I'm very close to JailBreaking my 1st IPhone ever but I still have some questions I need answered before I make the leap to do it........ Do the JB programs take up much memory/space on the IPhone 3g V2.2? How many kb/mb are they each? Also, I've read others' posts and I'm curious if a JBed phone has more of a "lag" compared to a stock one? Please let me know, even if it is a minor one. Thanks for the help!

No.

Jailbreaking does not have any impact on performance.

A word of caution though: while the jailbreaking process does not cause performance problems, it does make it possible to install some software that has been known to cause performance problems. Things like WinterBoard, MobileSubstrate, and Intelliscreen will take up additional RAM (and a bit of CPU time). Sometimes the performance cost of such features is worth it to some users, other times it's not.

Personally I don't use WinterBoard (due to the RAM usage), although my phone is jailbroken. I've got a ton of packages installed from various Cydia repos, and have experienced exactly zero performance problems.

Thanks for the quick reply! I know this is gonna be a dumb question, but I don't claim to be a computer wiz in the least bit, so........... if I were one of the people who decided the performance cost was not worth the feature and I proceeded to delete the program..... it is 100% gone and will not take up any RAM, right? The performance problems it may have caused would be gone also, and the phone would be as quick as it was before, correct?

It depends on what it is that's causing trouble.

The performance issues caused by WinterBoard and MobileSubstrate (the most common culprits) will indeed disappear if you remove the corresponding packages. I can't comment on Intelliscreen (not having ever used it myself), but I suspect that the same applies to it.

If you click restore in iTunes it will erase any signs of jailbreaking, and it will be like brand new. :)

[equlizer]

it slows down depending what you install:D I just un-installed a bunch of things and shes a lot quicker now.

Same here. I was using an extensive theme for a while, and there was lag. Not a great deal of lag, but enough to notice. I decided to nix the theme (I was getting bored of it), and went with what you see below (I crossed out my real name where the Carrier logo usually is), plus the AOL "You've Got Mail" for when I get email, and Status Notifier. Of course, I have a bunch of Apps (Backgrounder, NES Emulator, Cycorder, etc) that I got for Cydia, but those wouldn't affect performance unless I'm using them.

I really like it- it's clean and simple.

Sorry, I don't mean to hijack your thread but I can't reboot my iPhone after the jailbreak process in QuickPwn. I have a thread here (http://forums.macrumors.com/forumdisplay.php?f=105) if you could take the time to answer that would be great!!

Do a Google search. Regardless of what some of these posters report thousands of others complain about lag from jB'n iphones.

Don't listen to OrangeDog, he's totally against Jailbreaking so is bound to be biased.

I've had my phone jailbroken since day one. The jailbreaking alone causes no performance issues. Installing things like winterboard and intelliscreen that run constantly are a drain on memory and your battery. Stay clear of these. E

Even installing things like SBSettings and backgrounder causes little memory drain if you know how to use them properly.

Yep and your non biased?

Winterboard is one of the MOST popular thing installed on JB iPhones.

So jailbreaking alone doesn't cause a lag, it's what you do with a jailbroken phone that causes the lag. I dont have winterboard, intelliscreen etc because I know it will slow down my phone. I do however use SBSettings, Iphonevideorecorder, swirlymms because thats what I installed it for.

I am not being biased, I am well aware of the downfalls of jailbreaking. You, however, are close minded.

as apposed to using winterboard a person could Manualy SSH the desired Theme they want, not sure how that would have an effect on lag not to mention that they would be limited to that theme only

That's actually a good way to customize while avoiding the lag. That said, it's a lot tricker, and you stand a good chance of borking your phone if you don't know what you're doing.

And OrangeDog: Seriously. Your logic sucks. It's equivalent to saying that "Cars cause accidents because some people are bad drivers." Please, for the benefit of all new users, stop spreading FUD.

[jdzialak]

I just put my JB'ed 2G (on TMO) up against a stock AT&T 3G and speed tested them against each other.

I have Intelliscreen, Bluebird theme, Winterboard, and Status Notifier installed, to name a few...

The 3g opened SMS faster by about a second on first try. Closing SMS and re-opening a few more times had them opening simultaneously.
Email was about the same. 1st try was faster on the 3G.
Safari opened faster on my 2G...go figure.

Apple intentionally did not allow running apps in the background as the iphone is limited in power(like any cell phone, or computer for that matter).

Jailbrake programs do not have to live by apples code, so you can have 10 running at once, at your own peril. Just think of running a video, safari, office, etc all at once on your computer.

If you find your phone slowing(I surely don't), be more selective in what you run. No big deal.

[Moi un Mouton]

I have a jailbroken and unlocked 2G and I have not noticed any lag.

[egk69]

This have been said since post #2, but anyways.

I Jailbroke my 3G, just what they said, it depends on what you install on it, I have winterboard and a few other apps, and its kinda laggy some times, and the apps (every app) crash every now and then ,but its still better and faster that any other windows mobile phone i've used.

MINE (with winterboard and who knows what other apps) its slower than what it was before, kinda annoying sometimes, but anyways I can handle it. Im thinking of just modify the files on the phone via SSH , cuase I only use a few different Icons, and a few things, and I never change it and I think I never will, so I may do that and delete winterboard.

The 1st few days I use it, Jailbroken , but CLEAN (without apps at all) i was exactly the same as it was before jailbreaking it, I test it with my Bro's iPhone and both Perform exactly the same

Is the name of the thread "Does Winterboard slow the iPhone down?" Ok then.

[u49aa2]

mine was getting slow after i installed some applications. however as soon as i removed backgrounder. the iphone is back!

[carebearstare]

mine seems to lag through basic things like even typing and scrolling. and when i play need for speed i get choppy frames and long loading times. the only thing i dl-ed was cycorder and memtool. any idea what the problem is?

[eaglesteve]

Jailbreaking itself should not slow down the phone. The applications that you install however, may or may not slow it down. Winterboard does incur some performance penalty. You can always uninstall resource hungry application anytime.

[carebearstare]

yea...exactly but i dont think the video recorder is very memory consuming. i do have apps dl-ed from iphone like aim, sparta, and need for speed. dunno if those are the problem

[chrisgpix]

I used to have my phone Jailbroken mainly for tethering but thankfully with 3.0 that is longer necessary. I found my phone VERY unreliable in a jailbroken state, the best fault being that the phone would ring but the screen would stay blank meaning you couldn't take the call!...nightmare.

[JDM555]

I jail broke my phone 3 days after I got it. I dled some apps right away and was worried that it would lag. As soon as I did dl everything, I thought it felt a little sluggish in loading time and what not. So I went to my bro's 3g and did a few tests and if anything, mine loaded things faster. So I guess it feeling laggy was just in my head. No problems so far.

[kayno]

its funny cause the primary reason I jailbroke my phone was for The Ivillian theme (HTC Android Sense) I have a 3GS and I have noticed that it has made my phone like a second slower.. Its amazing how you can notice 1 second.. When I saw winterBoard on your list I was like damn, cause I was hoping it was the Jailbreak and not the one app I wanted.. BUt u know what though. I think I can give up a second for that theme.. Its not like my keyboard is laggin..

What is it making a second slower? On a 3GS I would not expect Winterboard to slow down, for instance, opening an application by a full second. I don't really even notice any difference on my 3GS with Winterboard, MobileSubstrate, and Several other apps running. YMMV.

Agreed. On my iPhone 3G I noticed a performance decrease. On my 3GS, not so much. I can't hardly live without mobile substrate though so the slight decrease is way worth it. The thing is, my jailbroken 3GS is still way faster than a non jailbroken 3G, and compared to my brothers unmodified 3GS it's less than a quarter of a second slower with winterboard themes and about 6 mobile substrate tweaks.

What exactly do you use other than winterboard??

Winterboard hasnt really slowed my phone down at all.

Truth.

I've tinkered around with all sorts of things. If you jailbreak on install the right apps, there will be no lag.

I upgraded my 3G to iOS 4. Jailbreak with redsn0w ONLY installing Cydia. When I did it and added the multitasking feature and wallpapers, it ran like a dog. After only installing the Cydia option, I have added SBSettings, Backgrounder, biteSMS, and mxTube, and it runs great. As stated above, you do need to know how to use them properly (don't put 27 apps in Backgrounder mode), but with basic intelligence you should be good.

[bigsexyy81]

And Winterboard made my phone a second slower as well. I don't use it anymore.

[stockscalper]

I have noticed no slow down with my 3GS running Winterboard, but the 3GS does have a faster processor than the 3G and that is probably the difference.

[Sparky9292]

Winterboard slows down 2G and 3G phones consideralbly. Jailbreaking alone has no performance effect.

Now the 3GS has a faster processor so you don't hear those folks complain as much.

[JbNoob]

The actual jailbreak process does not slow you down. What causes your iDevice to lag is certain applications or utilities which eat up your ram :(.
For example, if you have a 2g Ipod and download a package which allows you to multitask and use homescreen wallpaper, you will start noticing your device slowing down. Although jailbreaking does not slow your device down, Cydia, which is automatically installed when you JB, will slow you down, but it isn't very noticable :p.



Have fun Jailbreaking ;)

[Twin-D-Money]

Hi this message is for JbNoob or whoever can help. I dont know who said that jailbreaking does not effect the performance because my phone is extremely slow. I mean games lag rediculously. My phone freezes as if theirs a a major virus... If the jailbreak program is not the reason, i am really in concern of what is!?... Anyone have ANY suggestions of what i can do to fix this problem...? I have already tried:
-resetting the networking settings
-Clearing cache, cookies, & history
-Keeping my text messages completely erased

I dont know what else to do. I do have winterboard installed, do you suggest i delete that? Thanks so much for your help & responses!

My phone freezes as if theirs a a major virus... If the jailbreak program is not the reason, i am really in concern of what is!?... My apps dont even load up all the way it cancels out most the time. In the middle of a game is will lag out to the front. The slide to open takes so long to light up. It has a major hesitation before i can do almost anything. Sometimes it will work ok but thats no more than about 5 minutes perday! WHAT IN THE WORLD COULD I DO?! Anyone have ANY suggestions of what i can do to fix this problem...? I have already tried:
-resetting the networking settings
-Clearing cache, cookies, & history

I dont know what else to do. I do have winterboard installed, do you suggest i delete that? I use this for my business so it is extremely important to fix this. Thanks so much for your help & responses!
