    I updated from iOS 10 to 11 and I am getting:

    1) Worse battery life (with iOS 10 I literally just used the thing and never bothered about battery, it lasted *that* long. With iOS 11 it’s visible how quickly it drains the battery)

    2) There are dropped frames, stutters, transitions are not smooth, not always.

    3) Takes considerably longer to boot

    Quite a bad idea to upgrade! It kind of ruined a monster of an iPad less than 1 year old.

    Most of my settings are off or set to manual (manual email, notification almost all off, no background services etc).

    Anyone else in a similar situation?

    I have been experiencing similar issues as you. I'm not too bothered by 2 and 3, but the reduction in battery life is really bothering the heck out of me. To be sure, iOS 11 has some good features, but they're not as important to me as the peace of mind that came with impressive battery life under iOS 10. I would go back to iOS 10 in a heartbeat if I could. Alas, it's no longer possible to downgrade. :( I also hate the new App Store look.

    It really bothers me that they ruined my almost new iPad Pro. I am a 'principle' person. Was about to buy a new MBP and iPhone. Changed my mind. They can keep it. Plenty of other good phones and laptops.

    I’d look into doing a clean install to see if these problems persist. I don’t think it’s normal that you’re seeing such drastic battery life reduction under iOS 11.

    I have both the iPP9.7 and iPP10.5, both currently on iOS11. I have noticed no issues. Something may have just installed incorrectly. First I would recommend a fresh install of iOS11.

    Set it up as new; DO NOT RESTORE FROM BACKUP.

    I'm pretty sure that will fix it.

    I’d agree with the others that say to try a clean install.

    I noticed similar issues (though I never noticed poor battery life...) when i first installed iOS 11 on my 9.7, but after about a week they seem to have vanished.

    Righti. I reinstalled following the above procedure and the battery feels better, also animations feel smooth again.

    However, I noticed that the battery usage and standby are not working. I thought that I hadn’t charged it fully so I plugged it back on and once it reached 100% I unplugged it, and it started showing the elapsed times. Then I went to bed and turned it off.

    Today I checked the battery usage and to my surprise it’s not working again. It’s showing ‘-‘.
    Does anybody know why?

    If I am not mistaken,you have to continually leave the iPad in sleep/ standby mode if you want the OS to record the usage hours. Once you turn it off, it no longer works and will display the dash symbol.

    Thanks to sosumi and 960design. Setting up the iPad as new seems to have solved those problems. My mistake was restoring the device from backup. Thanks, guys!

    This. Do not turn your iPad off by holding the power button down and sliding the slider unless you plan on storing it unused for 90 days or more. Just let it go to sleep automatically at the 2 minute mark as set by default.

    Anytime! Glad it is working now. Sometimes crazy things happen, solar flares, presidential tweets, aliens, girlfriends...

    Whenever a major version of iOS is released you should always do a clean install and setup as new, in my opinion. iOS 11 was particularly major because of the new APFS File System, and when a new file system is being implemented you should never just upgrade, too many things can go wrong/haywire. Obviously you experienced that haywire aspect of upgrading.

    I know I will get tons of crap, saying that you do not need to do a clean install. I know there are people out there that just upgraded and had no issues, but in my opinion they were in the "lucky party." I always do a clean install whenever a new version of iOS is released, and I do the same when a new version of macOS is released. I have the same exact iPad Pro as you and I did a clean install of iOS 11 and have had zero issues. I think it runs ways better on iOS 11 than it did on iOS 10. I have a buddy that has the same iPad Pro as us, and at first he did an upgrade and experienced all sorts of issues. I told him to do a clean install and now it runs excellent.

    As far as your battery usage issue, you have to leave your iPad on for it to calculate your battery usage. If you power off your iPad, it resets the usage and that is why you are seeing the dash. Good luck bro!

    Thanks for the kind assistance, my iPad is perfect now! What a relief :) and what a difference a clean install has made. Makes me think that OTA updates should not be used then even for small updates? Going forward I will use iTunes for all updates, small and big.

    Hi, I know this thread has been inactive for a while, but did clean installing iOS 11 make your experience just as good as iOS 10 was? Are there still lots of frames drops on the newer builds of 11, and is the battery life just as good as 10?

    One more question I have that isn't related to iPad is that is there any way to restore just my messages onto a clean iOS 11 install? iBackupBot no longer works, and I'm planning on clean installing on my iPhone, but I don't want to lose any of my messages.

    Thanks!

    No issues on both mine and my wife's Pro 9.7's. We went from backup, like we've always done for years.
