9 Things to Know About the iPhone 6 iOS 10.3.3 Update



Apple’s iPhone 6 iOS 10.3.3 update is small but it could have a dramatic effect on your device’s performance.

The latest version of iOS 10 is a bug fix update that includes two dozen important security updates for the iPhone 6 and iPhone 6 Plus. It could have a positive impact on your iPhone 6 but it could also cause an assortment of problems.

The iPhone 6 iOS 10.3.3 update went through an extensive beta but problems like severe battery drain, broken Wi-Fi, and busted Bluetooth have slipped through the cracks into the final release.

Opinions about the iPhone 6 iOS 10.3.3 update are mixed and that’s precisely why we’re taking an in-depth look at its overall performance, its problems, and its usefulness as we push into the summer months.

If you’re coming to iOS 10.3.3 from iOS 10.3.2, you’ll get 24 security patches and some under-the-hood improvements with your version of iOS 10.3.3.

If you’re updating your iPhone 6 or iPhone 6 Plus from an older version of iOS 10 or iOS 9, your iOS 10.3.3 update will be much bigger. You’ll get everything from the iOS updates you skipped baked into your version of iOS 10.3.3.

Our roundup also includes some details about the iOS 10.3.2 downgrade, some tips to help you get the most out of iOS 10.3.3, and a peek at what’s coming next from Apple and iOS.

We’ll continue to update this page as we push away from the release date so check back in with us for regular changes.

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. 

If you need help to one side of the fence or the other, please take a look at our list of reasons to and not to install iOS 10.3.3 right now.

    This article is useless. Nothing that I didn’t know or think. Total waste of time.

    These are good points but I guess you forgot to mention that iOS 10.2 jailbreak is available now. So it is very important factor that people will consider when updating to iOS 10.2.

    I updated not to long ago to 10.2.1 and am noticing the battery drain, network connectivity issues, and bluetooth issues (all on AT&T iPhone 6 btw) since day one of download.

    I’ve got an iPhone 6 that is less than two years old. Since updating to 10.2.1, Siri stopped working. My microphone works — I can talk on the phone, I can use Voice memo.. but Siri? Done. No workie. Unbelievable.

    Since doing updates for I phone 7, my phone keeps telling me I don’t have enough storage, really? I have had this phone for 2 years and never had this problem. I’ve had to delete so many of my pictures, and so many apps, can this problem be fixed or is this just a way for them for you to buy the new phone, I phone 7, which i don’t want to do

    When I pressed the button (middle bottom) a box came up that has ALL THE OPTIONS I ALREADY KNOW & use. Now it jumps around the screen because it KNOWS when I’m typing! But in a game, it’s constantly in the way!
    There is NO option for it to go away or delete it. It’s a waste of space and I’m ready to go to another company. I got a big screen due to eye sight problems, now the little box with options I don’t need in my face WONT GO AWAY!
    How do I delete it, or I’m LEAVING APPLE!

    What a load of crap, my battery drains much quicker, I lost my network service for three days. I had to reset to factory settings only to find that now 1/3 of my memory is being used by “others”. And that is without installing the back up.
    Apple is really starting to suck, constantly breaking things to give you more useless shit. Then again they’ll soon run out of ideas.

    I have the iPhone 6 Plus with the newly updated IOS 10.3.1 and it hasn’t ruined my phone. Before the update nothing was wrong, after the update my phone glitches constantly, it’s non responsive to touch every other two minutes and it freezes up every five minutes. Apple needs to get it fixed asap.
