    I just wanted to update my post here.

    I've been experiencing choppy animations ever since 4.1 and I've narrowed it down to something to do with landscape mode.

    Open Safari
    Load a webpage
    Turn device landscape (with no orientation lock)
    Close Safari
    Re-open Safari (this is when I see the choppy launch animation).

    The first half of the animation is completely gone and only shows the last little bit.

    I can also do this with Notes, Mail, Contacts and a number of 3rd party apps also do this.

    Here's what the animation looks like normally:

    Here's what the animation looks like when it skips:

    I submitted the bug back when 4.1 came back out and they (Apple) still haven't fixed it.

    This sucks basically. The iPhone 4 was so smooth before 4.1 came out.

    Below is what my CPU usage looks on a regular basis. I have no idea what the iPhone is doing.

    The 4.1 updated didn't slow down my iPhone 4. Must be you.

    It didn't slow mine down it just makes the animation super fawking jerky. Pressing on emails to read them and opening folders. Plus the camera app.

    Thank you.

    Just because people can't perceive a problem doesn't mean it doesn't exist.

    Thanks for the notice on the free Activity Monitor app.

    Never knew how much ram certain apps took up.

    Nice little free app. I just wish i could find something like MemTool that showed each individual process memory/cpu usage but more updated.

    I wonder if it has anything to do with the HDR pics feature?

    I'm sure there's just a bug in the updated that Apple missed before release.

    Since the HDR feature wasn't in any of the developer builds, the general public is kind of beta testing the HDR function.

    I have faith that Apple will address this issue. They usually like to optimize their own Apple to use as little resources as possible.

    I wonder if this is the same reason that the iPhone 3GS users haven't been complaining. They didn't get the HDR feature, so their camera app was likely unchanged in 4.1. Right?

    That could explain the crappier battery life.

    Actually, it was recently discovered that HDR is in fact in the camera app for the iPhone 3GS. The plist file was set to false, so it wouldn't appear in the actual build, but with a jailbreak, you can enable HDR.

    And even on the iPod touch, with the camera app open, the device seems significantly slower. I truly believe there is something wrong with the camera app.

    Explains a lot. First it was the Skype app now these two. Apple needs a 4.1.1/4.2.1 update dedicated purely to bug fixes/performance enhancement. Does that app tell what clock speed the A4 is clocked at?

    yeah got my i4 the day 4.1 came out so i don't really know the difference between the firmwares but i noticed my i4 gets kinda sluggish after a while and the battery drains quite bad... also my phone has the reception problem too :(

    Yup probably. My battery life has gotten considerably worse. I could swear my battery life was in the 30% area, then less than an hour later in the teen %.

    Oh well

    The A4 is underclocked at 800MHz if I'm not wrong.

    Is anyone still on a non JB 4.0.x release? If so, could you post your CPU usage after a fresh boot?

    Thanks for the tip on the app. And the iPhone needs 1gb of RAM. Saved state causes Safari to constantly refresh because I only had 8mb of free RAM with my ususal set of apps leftt open. And why cant apps that analyze or display system info give the processor speed?

    My battery life hasn't been better than with 4.1.

    I would say, on my iPhone 4 at least, I haven't noticed that it is that much slower than with the original version that it came with.

    No it needs better software development. Having 2GB of RAM won't matter if the apps are badly coded and consequently highly inefficient.

    Apple must be blocking the CPU ID info.

    I made some new discoveries about this odd behavior. Read below:

    First of all, let me just say that all of my apps are closed and are not in the multitasking bar.

    1. I start up (nice and smooth animation) and do nothing.
    2. I close (just going back to the homescreen). This is also very smooth.
    3. I open (nice and smooth animation)
    4. Then I go back to the home screen and open photos again. This time it's not smooth. It's jumping to the foreground and the flying icon animation is missing.
    5. Each time I open after it starts doing this, is the same as #4.

    Here's another odd discovery:

    Again... I've quit all apps. Nothing is in the multitasking bar.

    1. Start up (nice and smooth animation).
    2. Do not take a photo and tap the photo browser button in the lower left corner.
    3. When the photo browser pops up, hit the home button and return to the home screen.
    4. Open (nice and smooth animation).
    5. Go back to homescreen and open Photos again. (Smooth animation again!)
    6. will continue to open smoothly every time now.
    7. Open again (not smooth. It features the same animation skip as #4 in the first test above.)

    Once either and starts stuttering like that, I can make it stop by completely quitting AND (I have to quit both).

    I think there may be something wrong with the HDR feature built into camera on iOS 4.1. I'm really hoping Apple can bring back the smoothness of 4.0.2 in a future update.

    Thank you for your time.

    App is now $2. Passing.

    4.1 hasn't slowed my phone down.

    Did you try what I posted above? I have 2 iPhone 4's and both of them do it.

    Talking about the skype app not sure if thats what you meant but it keeps running in the back even when I dont even open it at all.
    After a reboot it just loads up on its on as soon as the phone starts up.
    Weird, I remove it from backgrounding and it enables itself again.

    Why did I delete this app :( Now it's $1.99. But I do remember my iPod touch 4G showing mostly red on the monitor.
