Ran a little slow on my 7 plus so I left it overnight (UK here). This morning there was still a delay when opening apps, but I discovered that if I clear all apps from the app switcher, performance hikes up to very good levels. No lag noticeable. Only had to do this once and it's screaming now.

Just remember if you have a watch and you upgrade that to WatchOS 4, you are seriously unlikely to be able to restore your phone back to 10 and the watch still function properly. Ensure you're happy for "no going back" if you install iOS 11 beta and then WatchOS 4 beta.
Wow thanks for this tip. My iPhone 6 plus was horribly lagging, really unusable. A reboot did not change anything. Closing all apps though changed everything. Now it is just as snappy as before, maybe even more so. This means I will stick with it as my daily phone for now.

Does it stay like this even after opening many apps? My iPhone 7 plus was the same but I reverted to 10.3.3 before seeing this.

Could also be very well one misbehaving app. Closing them all and booting then does the trick. Or at least until you open the app...
 
I am currently switching back to iOS 10.3.2. It might work fine for others, but the battery life really is so bad I can't do it anymore. Additionally the camera is almost unusable at times. I will most likely test out the public beta when it releases, since those seem much more polished.
 
Useing iOS 11 beta on Air 2. had one crash with drag n drop. (opening photo app) but else, it seem to run preatty good for a beta 1 :)
 
Im running the DB on my iPad Pro 9.7 as its not a critical device for me. Ill probably wait until the public beta release or DB3 to install it on my iPhone 7 Plus. The iPad is mainly bug free for me. the occasional IU drops and others aren't really an issue and are expected with an early release build. The only real issue I've been having is getting apps to go into split view.
 
I put it on my 9.7 pro, as I did order the 10.5 pro so figured why not try it. It's actually not nearly as buggy as any other beta 1 I've tried. Very little lag, some crashes - but it's beta 1. Honestly it feels like a beta 3-4 on my iPad. I can't speak for the phone or other folks that are using it, as our usage is different. I will say the battery life seems better than iOS 10. I used it for 5-6 hours, browsing internet, steaming videos, and only lost around 15% battery and was multitasking the whole time.

I am going to put it on my iPhone yet, as I've been too frustrated in the past with betas 1-3 and daily driver on a phone is harder.
 
I’ve been using it on my iPad Pro 12” so far so good. Found a few little bugs but most of all it works really good. Thinking about installing on my iPhone 6+.

It's been running really well on my iPad Pro 9.7. A couple graphical glitches, nothing major.
Battery life has been great after a few days of settling down from the initial update and signing out of iCloud and back in.

Buggy, my screen keeps dimming. I adjust the brightness and it dims again. I know, its BETA:rolleyes:

Auto-brightness is broken on beta 1. Turn it off in Settings > Display & Brightness.

Yep agreed, the only one I’m struggling with is the series zero Apple watch dies regularly at around 4pm every day :)

Hmm. Not having that problem. I am using the Kaleidoscope face.
 
My biggest issue has been battery life (to be expected). Even with the Smart Battery case for my 6S it gets pretty close to dying by the end of the day.

Camera has also been incredibly unreliable, along with normal graphical glitches, control center glitches, and lock screen wallpaper changing to the home screen wallpaper randomly.

Overall, it's been pretty good for a Beta 1 and I haven't felt compelled to downgrade either my 6S or iPP.
 
Do all the apps from the App Store work well on the beta? Thinking of popping it on the 10.5.

Very doubtful. Devs cannot release app updates that use the internal calls implemented with iOS 11 until Apple calls for them (typically around a week or so before the GM release)... so, while some issues can be fixed, some cannot be without the new internals associated with iOS 11... and I've seen later releases break some apps... no way to tell what the affected apps would be... so if you have stuff that is mission critical, there's no way I'd be doing iOS 11 on a daily driver, at least not at beta 2.

No. There’s no beta yet at all. Some worked in developer preview but don’t work in dp2 and vice versa. You can expect this to continue throughout the developer preview and beta cycle. If its your only device and you rely it on it you would do well not to install the dp or beta.
