iPhone 6 iOS 11.4 Impressions & Performance
Before we relay our impressions, a few notes about the download and installation process.
The iPhone 6 iOS 11.4 update is a sizable download. It's several hundred megabytes if you're moving from iOS 11.3.1 and it should take you a couple of minutes to download it.
The installation process will take a bit longer and took right around eight minutes on our iPhone 6. Exact timing will vary from person-to-person, device-to-device.
For instance, if you're installing iOS 11 for the first time, or if you're moving up from an older version of iOS 11, your iOS 11.4 download and installation will take a lot longer.

The iPhone 6 is getting older, but our device continues to hold up fairly well as we push toward the release of iOS 12.
The iPhone 6 model in our possession is holding a solid charge with iOS 11.4 on board. We haven't noticed any abnormal battery drain during our stay on the latest version of iOS.
Connectivity (Bluetooth, cellular data, and Wi-Fi) is strong. We've successfully connected the device to Bluetooth devices (headsets and speakers) and several routers including eero mesh Wi-Fi.
App performance remains steady. We haven't seen frequent crashes or any catastrophic issues with our core applications which include Slack, Asana, Spotify, Chrome, and Gmail.
Random reboots have been a problem on our iPhone 6, but we haven't noticed any while using the iOS 11.4 update.
Unfortunately, lag continues to be an issue. Animations are still choppy and we continue to see keyboard lag when sending texts via Messages. This was a problem for us on iOS 11.3 and iOS 11.3.1 as well.
We've also noticed slowdown when pulling up Control Center from the bottom of the display and when pulling Notification Center down from the top of the display.
While there's certainly potential for problems, particularly lag, most people should install iOS 11.4 due to the changes on board.
That said, if you're feeling leery, take a look at our list of reasons to and not to install the iOS 11.4 update on your iPhone 6 or iPhone 6 Plus.
