Why iOS 7 will drive some of you nuts: UI lag due to slow animations [video inside]

[sniffies]

I've created this video for you to see how slow animations cause the UI lag.

The screen does not react to the finger swipes until the animation is 100% complete. The 1-2 second delay can surely drive you nuts, especially when you're in a hurry. It definitely affects your general workflow on the phone.

Unlocking screen is not the only place where it lags. Multitasking switcher is another one.

Anyway, here's the video, please note that the swiping speed is intentionally exaggerated in order to make it obvious how long the delay really is:

If it don't get fixed by the G.M, then it'll be a real issue, not that big of a deal tho since I hadn't even realized that probably like most people

True story. No fix = no update for me, and probably others will do the same.

Using iOS 7 feels a bit like using a pogo stick to get around. It's fun to bounce around the backyard for 10 minutes, but less fun if you have to use it to get to the store a mile down the street.

I remember on a previous iteration of iOS. Big fuss was made about being able to press things while an animation was going on, now Apple seems to have tossed that out the window.

I've uploaded another video that shows the lag within the multitasking switcher.

You should show the spotlight search lag. And the Control Panel and Siri.

And watch how hard it is to use folders.

My 4s lags as well on ios6. The unlock isn't that big a deal. Multitasking kinda sucks though...

This is what the iPhone 5s will be for...More power for faster unlocks.

I don't think you understand the root of the problem; iPhone 5 has nothing to do with the lag, it's the iOS 7.

Currently, your swipes are NOT registered until the animations are 100% complete. Whether it's iPhone 4S, 5 or 5S, the swipes still will not register. iOS 7 is to blame, not the hardware.

Well ios6 on my 4s is the same way...Just slow down some. Name an application where one needs to be in such a rush?

It's not apps, it's various situations where waiting the extra 2-3 seconds may not be an option.

I've definitely noticed it because I'm used to the faster animations of iOS 6.

 

[Di4mondz]

OMG...Yes, Apple please fix this delay/lag. This is bugging the hell out of me, especially what is shown in the first video.

 

[venetian-glass]

It's just not that responsive. Most times when you touch something. Nothing happens.

Which is bad because its supposed to be a touch screen interface.

Anyway, here's the video, notice how many swipes it takes to go to the next home screen after unlocking the phone:

P.S. Here's another video of multitasking switcher lag:

I would definitely suggest filing an official bug report to Apple. That way they will notice how serious this problem is. http://bugreport.apple.com

The multitasking lag is almost identical on iOS 6.1.3. There is also a delay with unlocking your phone on iOS 6.1.3, though not as long still present.

 

[TheRainKing]

It's not a bug, they just expect you to wait for the animation to fully complete before doing anything. They same problem existed when swiping between full screen apps on OS X but they eventually tweaked it after they found out it was annoying people.

 

[Vegasryn]

Not sure its lag because who uses their phone like that? Under normal use, I've never experienced it.

 

[teknikal90]

I myself am definitely annoyed by the unlock lag.
not sure who DOESNT use their phone like that....

 

[uberpooter]

Ah perfect, I just made a long reply in the other thread about iOS 7 being slow as dog ****. Glad you made these videos OP. But it'd be even better if we had iOS 6 next to it. It's insanely annoying how slow it is but I have faith.

 

[Osullivan1]

They seem to be fixing these issues now. Things like scrolling through folders before the animation finished work now, so I'd say these will be fixed before GM. Will defo be annoying though if not fixed.

 

[adnbek]

I sure hope they speed up the animations from what they are now. I recently restored my jailbroken phone in preparation for ios 7 and I think even 6 is painfully slow. I'm really hating the phone on stock after using fakeclockup (at 1.6x) for the past few months.... I'm so adapted to the fast animations that I find it currently unbearable at its current speed. I don't even understand why Apple even wants to artificially slow down the phone when it could be so much....ahem.... snappier by speeding up the animations.

If 7 is even slower, that really sucks.

 

[peacenfunk]

Who really swipes like that?

 

[kre62]

Beta 4 animations were faster.

I'm hoping for the animation speed of the iOS7 Video on apples website

 

[thekingofnerds]

That is a little nuts - there's a good quarter to a half second delay between the animation ending and the swiping. May not sound like a lot - but there's no reason for the delay.
