5 annoying iOS 11 problems and how to fix them

Drop in performance

Some users are experiencing performance issues with iOS even on newer devices, not to mention older ones like the iPhone 5s. The iOS 11.1 update partially fixes the situation, but if your iPhone or iPad continues to lag, you can try the following.

Clean up free disk space.
Reset the gadget to factory settings ("Settings" → "General" → "Reset" → "Erase all content and settings") and configure it again, after saving a backup to iCloud.

Fast battery discharge

Like any new OS, iOS 11 sometimes causes the battery to drain faster, resulting in lower battery life. This is usually fixed by subsequent software updates, so be sure to install them as they are released and be sure to update apps in the App Store.

Traditional tips like using power saving mode, lowering the display brightness, turning off background updates, and geolocation services also work.

Broken Wi-Fi and Bluetooth switches

You may not have known, but disabling the corresponding toggle switches in Control Center does not actually turn off the Wi-Fi and Bluetooth modules. They simply terminate the connection to the current network or device, remain active, and continue to monitor other networks and devices.

To completely disable the wireless modules, you need to open the settings and turn off the corresponding toggle switches in the Wi-Fi and Bluetooth sections.

Crashes and freezes of applications

Many users experience problems with the incorrect operation of applications in iOS 11. The most common problems are associated with the discontinuation of support for 32-bit applications, as well as with the new compression formats HEIF and HEVC, which may not already be supported by the applications themselves.

In this case, you can recommend uninstalling and reinstalling the broken application, and if this does not help, wait for an update from the developers.

Calculator errors

An unpleasant feature of the calculator in iOS 11 is that when you enter numbers quickly, it gives incorrect results, skipping intermediate operations due to drawing animation.

Some people joke that this is not a bug, but a feature, but if you do not want to make mistakes in important calculations, it is better not to rush when entering numbers or use step-by-step calculations by clicking on the equal sign after each operation. Or install an alternative calculator from the App Store.
