Apple iOS 11 battery and outlook problems: how to fix them

Apple’s latest edition of its iOS operating system isn’t hurting for users. According to statistics from the mobile-analytics firm Mixpanel, a week after its release, iOS 11 was already running on 24% of iOS devices.

But this new update is also exhibiting some issues—yes, much like every operating-system update ever. Here are a few we’ve heard about, along with possible steps to remedy them.

Battery life

Users on Apple’s tech-support boards have posted gripes about what this update has done to battery life on their devices—see, for example, posts from users of the iPhone 66s, and 7 Plus.

The likeliest fix for that: Give this update time. As veteran Apple watcher Rene Ritchie explained at iMore, the moving-in phase for a new operating system is power-intensive: Wi-Fi stays on to download app updates, while the Spotlight search system works to re-index the system. 

“When radios and processors can't sleep, power consumption goes way up,” he wrote. 

To be sure you don’t have a rogue app doing a number on your device’s battery, follow Apple’s advice and open the Settings app, then tap Battery. If an app has a “Background Activity” label below it, tap the clock icon to see how busy it’s been when not in use.

Microsoft-related mail malaise

Apple has already confirmed one bug with iOS 11: Its Mail app can have issues sending messages from accounts on Microsoft’s Outlook.com, Office 365 or Exchange Server 2016 systems. As a tech-support note posted  last week warns, Mail may show a “message was rejected by the server” error and leave your outgoing e-mail stuck on the device.

(The Outlook.com account I set up on an iPad mini 4 did not exhibit that behavior, though.)

The note says “Apple is working closely with Microsoft to resolve the issue and will release a fix soon in an upcoming software update.” In the meantime, a Microsoft tech-support note reminds iOS 11 users that they can work around this by installing the company’s free Outlook iOS app.

ARKit absences

Before installing iOS 11, you should have seen an onscreen warning about it not running apps written for the “32-bit” architecture of older iOS versions. (If those titles haven’t been updated almost three years after Apple’s first warning to developers, don’t expect a fix now.) But a different sort of incompatibility can surface with new apps that employ iOS 11’s ARKit augmented-reality framework. 

This software allows apps to overlay objects over the camera’s view of your surroundings with remarkable precision—you can see how furniture would look in your living room, for example. But what Apple doesn’t say upfront to customers is that ARKit won’t work on many iOS 11-capable devices. As a page for developers clarifies, this feature requires its A9, A10 and A11 processors, a stipulation that excludes the iPhone 5s and 6 as well as every iPad Air and iPad mini.

Fortunately, as any Pokemon Go user can attest, you don’t need iOS 11 to enjoy AR. Apps offering this software-assisted perspective have been widely available since at least 2009 (see, for instance, Yelp’s nifty Monocle view); without ARKit, you simply lose a bit of finer control.
