iPhone Users Complain of App Slowdowns and Performance Drops After Installing iOS 11

Following the release of a new version of iOS, there are typically complaints about battery problems, issues with apps, and minor bugs, and the launch of iOS 11 has proven to be no exception.

On reddit, numerous users who have installed iOS 11 claim to be experiencing much slower app performance, app crashes, and other similar issues. The initial reddit post calls launching apps "an absolute chore," a sentiment echoed by dozens of additional comments.

Ever since I upgraded, launching apps is an absolute chore. Safari, Reddit, ESPN, Yahoo, texts, etc all have a terrible time opening. They either crash back to home, freeze and require closing the app or take well over a minute to load. I never had a single issue with my 7+ before last night and now suddenly it's like this phone is stuck in quicksand. I've never had to hard reset this phone before but I've had to do it twice in the past two days.

Users are complaining that their phones "just get stuck on apps" and that a hard reset is the only way to fix the problem. Reddit, Snapchat, Twitter, Facebook, Messenger, Safari, and more are all affected apps. Sometimes, apps refuse to open just launching from the Home screen, while at other times, apps launched from Notifications won't work, and there are issues with Bluetooth.

I've been using the beta and it's been super fine for me. But now on the GM I get all the same issues. Apps don't launch, or if they finally do they crash. Things are freezing and crashing. Sometimes just bringing up CC stalls my phone and makes it unresponsive. Something in the update broke the Bluetooth controls connection and now I can't use the skip button from my transmitter (which worked in the beta) to change songs.

The Now Playing widget in the Control Center is also a chief complaint, with multiple users unable to control songs on Spotify and Apple Music using the widget, and some users say their battery life has taken a serious hit since updating.

Not all customers who upgraded to iOS 11 are seeing these issues but based on the reddit thread, it seems a fair number of people are having problems. App updates and subsequent iOS 11 updates are likely to resolve these issues over time, but customers who want an immediate fix can try some of the methods reported to work on reddit

Some reddit users claim that resetting their settings (Settings --> General ---> Reset --> Reset All Settings) fixed all of the app issues, while others have restored their devices and set it up as new to solve the problem. Others have backed up and restored and had better results. From one reddit user on backup and restore:

Exactly. I think people think this is a placebo effect but it really does work. Brought my 6S from a sluggish beast to more or less the same performance I had in iOS 10.

Multiple iPhone models appear to be affected, with redditors reporting issues on the iPhone 6s, iPhone 7, iPhone 7 Plus, and other earlier models. The iPhone 8 and 8 Plus do not appear to be affected, and there are few complaints about iPad Pro models.

This simply can’t be true. Apple’s software is perfection. Those complaining might have mixed up Touchwiz with iOS 11.

Planned obsolescence? Yeah, iOS11 is super slow. I love my iPhone, but seems like a sales tactic.

It's re-indexing. The first 2 days my phone was super slow, now it's moving much faster. Of course, maybe I'm just used to the slowness now. :-)
