Quick iPhone 6 iOS 10.3.3 Review
The iPhone 6 iOS 10.3.3 update isn't very big and it should only take you a few minutes to download and install on your iPhone 6 or iPhone 6 Plus.
If you're coming to it from something older than iOS 10.3.2, expect the process to take a bit longer due to the upgrades you missed.
We recommend putting aside 15-20 minutes of quiet time in order to monitor your iOS 10.3.3 download and installation for problems. For a closer look at how long it will take you, take a look at our guide to the iOS 10.3.3 download.
We've been using the iPhone 6 iOS 10.3.3 update for a few weeks now and we've been taking a close look at key areas of performance including battery life, connectivity, and UI speed. Here's what we've learned so far.
Some iPhone 6 and iPhone 6 Plus users are complaining but we haven't noticed any abnormal battery drain during our brief time on iOS 10.3.3.
If you recently installed iOS 10.3.3 and you're noticing issues with your iPhone 6's battery life, give it a few days to settle in. If you continue to see issues with your battery life, it's time to take action.
We've tested the iPhone 6's update with several routers (including the eero mesh Wi-Fi system) and Bluetooth devices. We haven't run into any issues yet. AT&T's LTE and 4G networks are also functioning normally with iOS 10.3.3 on board.
We haven't noticed any random reboots and the phone's UI feels fast. Animations and transitions are fluid and we haven't encountered any weird lag or sluggishness when opening folders, apps or Control Center.
We've only spent a few days with the software but as of right now it feels stable. And given what's on board the update (a ton of important security patches), it's certainly worth a look if your iPhone 6 is already running iOS 10.
If you're on an older version of iOS, say iOS 9, you might want to wait a few days so you can gather a little more feedback about performance.
