9 Things to Know About the iPhone 6s iOS 10.3.3 Update

The iPhone 6s iOS 10.3.3 update is a small but important release for the former flagship and today we want to take a look at the key things iPhone 6s users need to know about the latest upgrade as we push toward the release of iOS 11.

Apple’s iOS 10.3.3 update isn’t a milestone upgrade but it could have a significant impact on your iPhone 6s or iPhone 6s Plus’ performance.

Many iPhone 6s and iPhone 6s Plus owners are complaining about frustrating iOS 10.3.3 problems though many others are having an excellent experience on the current version of iOS 10.

If you are coming to iOS 10.3.3 from the iPhone 6s’ iOS 10.3.2 update, your download will be pretty small. If you’re coming to iOS 10.3.3 from something older than that, your iPhone 6s iOS 10.3.3 update will be much larger thanks to the previous versions of iOS. Features and fixes from those updates are included in your version of iOS 10.3.3.

Now that we’re a few weeks removed from the iOS 10.3.3 update’s release we want to take an updated look at the most important things you need to know if you’re already using iOS 10.3.3 or if you’re thinking about installing iOS 10.3.3 on your iPhone 6s or iPhone 6s Plus.

Our guide looks at the iPhone 6s iOS 10.3.3 update’s performance, the current state of iPhone 6s iOS 10.3.3 problems, the iOS 10.3.2 downgrade, and the update that could replace iOS 10.3.3 in just a few short days.

Before we get into the iPhone 6s iOS 10.3.3 update's performance, a quick note about the iOS 10.3.3 installation process.

The iOS 10.3.3 download/installation process took us about seven minutes to complete. We upgraded from the iOS 10.3.2 update. 

If you're coming to iOS 10.3.3 from an older version of iOS, your installation could take longer. For more on the download/installation process, take a look at our walkthrough.  

We've been using the iPhone 6s iOS 10.3.3 update for a few weeks now and the update still feels extremely stable. 

Battery life is holding up and we haven't noticed any abnormal drain on the iPhone 6s models we're using to test iOS 10.3.3.  

If you recently installed iOS 10.3.3 and you're seeing abnormal battery drain issues, give it a couple of days. If the problems persist, you'll want to dig into some fixes.

We've tested the phone and the update with a few different routers (including eero) and Bluetooth devices. We haven't noticed any major issues with our connections. They remain strong, reliable, and fast.

The user interface is still fast and we haven't experienced any lag, random reboots or freezes during our testing. 

So far, the transition from iOS 10.3.2 to iOS 10.3.3 has been extremely smooth. We haven't run into any significant iOS 10.3.3 performance issues. At least not yet.

iOS 10.3.3 is definitely worth a look if you're running into issues on an older version of iOS 10 or if you're concerned with your device's security. 

If you're coming from an older version of iOS, like iOS 9 or iOS 10.2.1, you might want to snag a second opinion before installing the update on your iPhone 6s or iPhone 6s Plus. 

If you need additional feedback, take a look at our reasons to and not to install iOS 10.3.3 today.
