Q: iOS 8.4 slow wake on iPad Air 2

After upgrading to iOS 8.4, I noticed that there is a 1-2 second delay before the screen turns on after waking it up.  This generally happens if my iPad has been locked for a few minutes and I'm certain that this wasn't present in iOS 8.3.  Has anyone else noticed this behavior?  I'm going to submit a bug report to Apple, but wanted to reach out to the community first...

iMac, Mac OS X (10.7.1)

    Hello all.  I have a 64 GB iPad Air 2 Wifi & Cellular and I upgraded recently to iOS 8.4.  I'd just like to add myself to this growing list of people who have noticed both the lag and rotation issues particularly when waking up the iPad Air 2 after several minutes sleep.  To recap:

     

    1) On pushing the home or sleep/wake button, there is this noticeable lag before the home screen appears.  This only happens after the iPad goes to sleep for an extended period.  If you press either button shortly after the unit goes to sleep then the response is normal.

     

    2) Again, when waking the iPad up after an extended period, the screen frequently does not reorient itself (from landscape to portrait and vice versa as the case may be) and I need to press the home button again for it to get this done.

     

    To date, I have only done a hard reset but the issue still remains.

     

    And last night, I experienced my first ever crash (reported in other parts of this forum).  Was watching videos using the Youtube app when the audio suddenly stuttered then the blue screen appeared, then the Apple logo then a restart.  So far, there have been no recurrences.

     

    I have an old iPad 2 and an iPhone 5s (both updated to 8.4) and there have been no problems with them.

     

    Hopefully, the good folks at Apple are taking note and a fix is on its way.

    You sure put in the overtime to uncover this one. Sorry I can't award you points. Actually I can, if you get 5 this helped me by readers you get a gold star when possible. Let me give you one here and I'll go over to the other post and see what I can do there.

    Enjoy the rest of the Fourth. Isn't their a Dodger game you could be watching ?

    Yes, Reduce Motion enabled (no parallax effect) is what causes the screen rotation issue. Having it off (parallax effect present), there is no rotational issue.

    Darn, read it wrong again. I'm testing now. I turned on Reduce Motion and I will give the iPad a few minutes to sleep.

     

    Wishing both you and Demo (and all others here that celebrate) a Happy 4th as well. I've already BBQ'd our burgers & hotdogs...and myself as well. SoCal summer heat stinks. Fireworks will likely be viewed in HD tonight, in the comfort of our home.

     

    Our partying is over for the day as well.

     

    We took a trip to the Pittsburgh Zoo today with my wife's sister and her husband and checked out the new additions to the place. We love the zoo and its one of the great treasures of our wonderful city. After the trip to the zoo, we had dinner out. We let someone else do the BBQ-ing this year. Fittingly enough, we ate at a restaurant called Carnivore's which is a local sports bar that is located pretty close to where we live. The ladies have had enough for the day, so we will just be hanging out at home now. I can hear the kids in the neighborhood setting off firecrackers and the like as I sit here typing away. I will probably head out to my back deck, turn on the TV and catch the fireworks for the capitol.

     

    Checking on the iPad now ....Wow, you hit the nail on the head SergZak. With Reduce Motion enabled, the iPad will not rotate either coming out of sleep. I turned it off in the settings, and after tapping the home button, the screen rotates again. Great investigative work. I wish I had points to award you as well. We should all file bug reports using SergZak's findings.

     

    Sorry to all of you other folks for hijacking the thread with our tales of 4th of July celebrations. Enjoy the rest of the holiday everyone!!!

    You do have points to award, the readers choice helpful remember. I just put SergZak over the top in one of these threads. Let's see if we can get him a second one.

    I remembered that after I posted. I have been awarding where they make sense in this and the other thread.

    Seems to be an iOS 8.4 bug or maybe it's "by design" now for some odd reason...who knows. I've not found anything to alleviate the issue other than using a Smart Cover/Smart Case (magnetically triggered wake). In this case, there is no wake delay.

     

    BTW, for those interested, the sleep time required before the delayed (~one second) wake will occur is 15 - 20 seconds. Waiting any longer than that is just wasting your time.

    Aloha SergZak.

    Just curious. Do you get the delay if you use the power switch to turn on your iPad ? How about when you plug in the charger ? Might as well check all avenues.

    Stay well.  Bob.

    Greets, Bob...

     

    Waking from Sleep/Wake button or Home button both cause the delay

    Waking from Smart Cover/Smart Case (magnetically) or by plugging into a charger does NOT cause the delay.
