iPhone Extremely Slow

[thisisarcadia]

My iPhone 3G has been extremely slow ever since i jailbroke it. It usually freezes a lot and when i turn it off and turn it back on it usually takes about 5 minutes to reboot. Has anybody had this problem when they jailbroke their phone with quickpwn. Because frankly it kind of sucks for it to not run very smoothly!

[Ol3s]

You could restore it and jailbreak again.
But the reason for the slowness could be the cydia or installer, if you install a lot of sources that happens (it happened to me)

theres a reason people dont jailbreak

Jailbraking doesn't slow your phone down.

I have Jailbroken, but mine hasn't slowed down. But, I also haven't installed lots of pointless applications.

I've got what I need and am happy with that

People don't JB either because they don't need to or don't want to (or don't know how to)

[mavis]

I've jailbroken about once a month since September. I usually end up restoring it after a week or two (tops!) due to the VERY noticeable slowdown. It seems to get worse after a week or so. YMMV.

Dun... dun... dun... Another one bites the dust!

I don't know if it's because my iPhone is jailbroken or if it's because the iPhone has the phone feature, but my 1st generation iPod Touch is MUCH more responsive than my iPhone 2G.

I doubt it's because of the jailbreak though, giving the user account root access to the iPhone(which is essentially what you do when you jailbreak) wouldn't slow down the device.

It's because the iPod Touch doesn't have to run all the background processes that the iPhone has to run.

[lavrishevo]

Jailbreaking in itself does NOT slow you phone down. It is the programs that run in the background that slow the phone down. These include Winterboard, Intelliscreen, and others. Even Winterboard will very slightly slow the phone down with a small theme being used. If you are wondering why you phone is slow look at the programs using up your processor and ram running in the background and you will find the culprit. But don't take my word for it. Jailbreak and just install programs that do not run in the background and you will see for yourself.

Err... no. The 'mobile' user is still just a regular user account.

[willhart]

I've jailbroken my phone for over 6 months now. It's a 3g. I did notice a slow down when I had winterboard and themes enabled so I've disabled it. Anything that will change the look will slow it down, even changing icons at the top, etc.

I wouldn't go back to a non Jailbroken phone now that xGPS is out with downloadable google maps and audible turn by turn directions. This is basically the GPS program that everyone has been waiting for.

[buccsmf1]

yea i've noticed a slowdown in my jailbroken iphone recently. It was fine for about a week and then programs began to take noticeably longer to load. Haven't had any problems with crashing or freezing but app loading time has probably doubled.

Yup, sounds EXACTLY like what happens to me, every time. It's really frustrating!

[kenkamm]

I resisted jailbreaking for a long time. I decided to give it a try since it's easy to revert. When I first jailbroke I didn't install anything. Used it for a week like that and I couldn't tell the difference from my stock phone (makes sense.)

I did not install Winterboard at first because of everything I heard about it. What I really wanted was clippy or hClipboard. I installed hClipboard and still didn't really notice a difference. Maybe slight, but it could have been in my head. Certainly not a bother.

To keep things simple and continue testing, I uninstalled hClipboard and installed Winterboard, and downloaded the "badge black" theme which does change the look of quite a few things. I only checked the "badge black", "badge black UI" and "user wallpaper" in Winterboard. I really don't think the phone slowed down much, if at all, and I was quite happy with the new look.

I reinstalled hClipboard and additionally installed the 5 icon dock and LockDockBar. Finally I am now seeing some slowdown on the phone. If I restart it each night before I charge it, it remains reasonable throughout the day and I really like having the new look and new features.

Then I deleted LockDockBar and replaced it with StatusNotifier, and also installed the 5-row qwerty keyboard. That was the limit for me - the phone seemed really sluggish. I went back to LockDockBar (I prefer it because it shows you the number of txts and emails) and got rid of the 5-row keyboard (I am so used to the stock one that the 5-row drove me nuts) and now all is well.

My conclusion is that the things that really seem to slow down the phone are things that use MobileSubstrate. Right now I'm down to LockDockBar, Winterboard, and 5-icon dock, and the phone seems snappy.

Wow, that post was too long.

How can you view the process and CPU% usage?

[Katuls]

I've jailbroken my iphone and ipods ever since 1.1 era.. Probably over 100 times on different apple products. The reason I always go back to restoring back to stock is because of the slowdown. Trust me, for all the people who say "you didn't doz it rightz", it's a pretty easy install. You can't really mess up if you have any clue about jailbreaking. It never is as seamless and responsive as a non jailbroken iphone. Easy as that. Sorry to all you jailbroken users; my 100+ times prove the fact that it does slow down.

[muckymucky]

winterboard = slowdown at least 20%-200%

[TheSpaz]

I usually jailbreak for fun, but when I want a fast iPhone, I stay stock. By the way, if you're jailbroken, install the top command and run it over SSH to see your processes and memory usage.

No. It doesn't prove anything, other than you perceived a difference between the two. Whether or not there is any difference in the responsiveness of your phone before and after your modifications I have no way to know. I do, however, know what the jailbreaking process does and does not do -- and one of the things that it does not do is cause increased CPU and memory usage.

Jailbroken phones can certainly be as "seamless and responsive" as stock ones. It's entirely dependent on what modifications you perform to said jailbroken phones.

Anyone who tells you otherwise is either poorly informed and/or OrangeDog. ;)

Lag is going to happen if you install anything. It's inevitable. I'm tired of people coming here and trying to deny it.

It's either worth it for the modifications or it isn't.

The thing that makes me laugh is... We've tried jailbreaking... we've tried liking it.. and every single time, the lag makes me restore. When I'm not jailbroken, I have no problems (other than the bugs Apple hasn't worked out yet).

At least I know that when I'm not jailbroken, any type of lag or anything is not the fault of a jailbroken app with a memory leak or something. I think 2.2.1 runs VERY efficiently... especially Safari. Safari has gotten a lot more stable since 2.2.1.

How is that at all the same thing? Are people coming on here complaining about apps they created causing problems? Didn't think so.

Most of these apps and tweaks are made by people who know what they're doing.

[marksandvig]

That proves you have an opinion.. A well educated opinion.. but an opinion.

[TheSpaz]

It's all about user experience. If a user jailbreaks and experiences problems... of course they're going to have a different opinion than a user who jailbreaks and doesn't have problems (that they notice). I think a lot of jailbreakers don't time the opening of their apps, so they go on here and say "I get NO slowdowns and I run all the goodies"... they're full of crap or they just don't notice a difference... but, just because they don't *notice* a slowdown, doesn't mean it's not there. It's all about perception... that's all. If you sit there and count 1-mississippi, 2-mississippi you're going to start to see the difference, but nobody does that unless they're me.

So what's your loading time for apps without a jailbreak? Is it 1 second? It's not, we all know that for sure. A fresh OS with 1 page of apps might take 2 seconds at the very fastest to open up an app. Mine is about 4-5 seconds with a jailbroken phone, with all 9 pages filled, and not having restored since 2.2 came out. If it weren't jailbroken, it would take 3-4 seconds for an app to open up with 9 pages and this long since a restore. So you might save 1 second with your virgin OS. I guess 1 second is worth having a limited phone for some people. Now if you're gonna go theme, backgrounded, iltelliscreen and all that other stuff crazy, then you'll have significant slowdown. The iPhone's small amount of ram can't handle only so much, so you have to be smart about what you install.

I get about 1.25 seconds to open apps. I say "One-One thousand" and just as I'm about to say "Two", my app is ready to be used. This means, the app's interface is up and responding to touch. I understand that saying "One-One thousand can be said slower or faster.... but, that's just a rough guess... I don't have a stop watch I can sit there with.

I deny it because it's not true.

I've installed OpenSSH, mDNSResponder, netcat, gzip, bzip2, lynx, wget, BossPrefs, and a couple other userland applications on my iPhone. Guess what? No lag.

It's not going to happen if you install "anything". It's going to happen if you install packages that require either MobileSubstrate or a number of resource-intensive daemons. If you avoid those, you won't run into performance problems. Trouble is, most people don't, and that's where the "jailbreaking = lag" FUD comes from.

Thats the common thing that lots of people find out after JB'ing.

The one good thing about it is.....that when you go back to stock you really appreciate how snappy and responsive it is again and not running like a 3 legged dog.

[ppc750fx]

Wow, another "JBing slowed my phone down" post..... wait.... You smell that... Yeah me too. Smells like bs!

JB doesn't slow your phone down folks. Some apps might, but JB does not.

[TheSpaz]

No, but Apple can and does...and that is why we jailbreak. :)

Here are some of the things I don't need:

PDAnet (I don't have a laptop)
Cycorder (I don't need to shoot video on my cell phone... I have a video camera that is much better at doing that job)
Status Notifier (It was cool when I had it, but nobody ever calls me and it's not hard to unlock the iPhone to check for mail)
3rd Party SMS app (they cost money and usually aren't as elegant as Apple's)
A different Browser (Come on now, Safari never crashes on me anymore)
SBSettings (Again, not important to me because I never change my brightness, disconnect from wifi or turn of 3G and my iPhone has PLENTY of power at the end of the day. I also leave bluetooth on). I suppose if I were jailbroken and had a bunch of extra stuff running, I would have to watch my services to get through the day with enough battery, but I don't have to worry about it.

I just don't "need" to slow my phone down. Some of you NEED those things, so you don't mind living with a slower phone, but personally, I just don't see the advantage... all I see is a slower phone with unnecessary add-ons.

Some of the stuff you mentioned has no performance impact. Things like Cycorder and third party SMS apps don't require any background processes, nor do they need MobileSubstrate -- so for those apps, there's no performance tradeoff.

OrangeDog et. al. are claiming that jailbreaking slows down your phone because some people install applications that have performance problems. In actuality, jailbreaking itself doesn't slow down your phone, and that there are plenty of applications that don't have performance issues.

Now you can try to spin it by saying "ah, but it's the problematic applications that most people want", but that just makes it seem like you've got something against jailbreaking and are trying to twist the facts to fit your claims...

If you don't see any point in jailbreaking, fine -- run stock. There's absolutely nothing wrong with that. Just because you don't see any value in it doesn't mean that other people don't find it a useful procedure; so please don't try to dissuade them by sowing FUD about jailbreak causing lag.

The deal is. I don't think we're spreading FUD. The people will do and install what they want. If they *want* the special features at the cost of a laggy phone, all power to them. We're not saying that EVERYONE doesn't know what they're doing. I know that Cycorder won't slow the phone because it's not running all the time, but that's not what I would jailbreak for anyway.

Right now I have my iPhone password protected, but if someone wanted to read all of my text messages, they could simply connect the iPhone to the computer and read them... without even jailbreaking! If they wanted to see my photos... my recent calls, my music... all without jailbreaking. How's that for security? It's bad.

I don't care if every person besides me on the planet who has an iPhone Jail*breaks* it. It's their iPhone and they can do what they wish with it. I think your pro views on JB'ing blind you to the fact that the BIGGEST complaint of JB'ing is lag followed by a close second by flakiness. It's an undeniable fact that people suffer lag when they jailbreak and start to install THE most popular apps that are heralded as some of THE reasons for JB'ing in the first place.
And please don't plead the case of Winterboard being the culprit. Thats a very tired, old and very well worn out chestnut. I've seen countless JB'n iPhones and they all have had Winterboard installed on them. I don't doubt that there are geeks out there who don't have Winterboard installed, but you have your head in the sand if you don't think the average JB'er doesn't install Winterboard soon after JB'ing.

[ppc750fx]

And that is the crux of your argument. You're basically saying that jailbreaking = lag because you think that most people install WinterBoard. Now I don't know whether or not most people do install WinterBoard, but even taking you at your word you're still making a very misleading argument.

Many people jailbreak for the purpose of gaining additional features (turn-by-turn GPS, video recording, vCard support, etc.) If you keep posting stuff like "The biggest problem with jailbreaking is the lag", then people who want these additional features might be dissuaded from jailbreaking if they think that there some inherent problem with the process.

I'm not asking that you stop complaining about the lag caused by MobileSubstrate apps. That's a completely justified complaint -- hell, the performance issues with WinterBoard was the reason I stopped using it. Instead, I'm merely asking that you stop being so imprecise in your complaints as to imply a problem with jailbreaking as a whole. Doing so gives the wrong impression to newbies, and makes it seem like you're engaging in some sort of crusade against jailbreaking.

What do you say to the people who claim to have WinterBoard plus a bunch of other MobileSubstrate apps running and don't have any lag? I say they're full of crap but, they claim to have tested this against un-jailbroken iPhones.

Why is this debate still going on? Every time I look at this board, there's some thread about why people should or shouldn't jailbreak. Who cares?

The holier than thou, my iphone is stock and jailbreak sucks attitude is terrible.

If you want to jailbreak, then jailbreak.

If you don't want to jailbreak, then great.. don't.

Why is everybody always trying to make decisions for everybody else?
