iOS 12.5.6 is a small point update and it brings an important security patch to the iPhone 5s and other devices left behind on iOS 12.

While most iPhone 5s users should download iOS 12.5.6 right now, some users might want to wait a few more days before making the move up from iOS 12.5.6 or an older version of iOS.

Some iPhone 5s users are already seeing performance gains after installing iOS 12.5.6. That said, some iPhone 5s users are running into problems with the firmware so you need to proceed with caution. This is especially true if you’re running an older version of iOS.

If you're moving up from iOS 12.5.5, the iOS 12.5.6 update requires a pretty small download.

If you're moving from an older version of iOS, your download will be bigger and your installation will take a bit longer. That's because the features from the updates you skipped are baked into your version of iOS 12.5.6.

We've been using iOS 12.5.6 on the iPhone 5s for a short time and it's running pretty well on our phone.

The heavy UI lag that tormented us on older versions of iOS 12 is still missing though we've seen a little bit of choppiness when pulling up Control Center, Notifications, and while using the keyboard.

Swiping to the camera on the lock screen is still fluid and apps still open up much faster than they did on previous versions of iOS 12.

We haven't run into any battery life issues nor have we run into any connectivity issues (Wi-Fi, Bluetooth, GPS, etc). 

Apps appear to be working well for the most part and we haven't noticed any crashes during our time with iOS 12.5.6.

We haven't noticed any game-changing bugs or issues and that's a good sign as we push away from the release date. 

We recommend downloading iOS 12.5.6. If you're in need of additional feedback, take a look at our list of reasons to and not to install iOS 12.5.6 right now

    I bought my iPhone 5 plus 6 months ago. It urged me to upgrade from iOS11 to iOS 12. I did as instructed but encountered a big problem – I couldn’t recharge the phone. I took it back to the dealer and it somehow fixed it. They told me that there was a problem with iOS 12 for older phone, and one of the problems was refusing to recharge. I am now a bit worried about upgrading to iOS 12.1.4. Please advice.

    My iPhone 5S won’t let me backup the phone, it keeps saying there was an error! I got a new battery and it keeps running down quickly so I wanted to reset the phone but I need to backup the phone first. I did the upgrade but it still won’t let me backup! Does the cord make a difference?

    I upgraded my, original still used, 5S a couple of days ago when I saw the 12.5.1 update. Now when my phone hits 50-60% battery it goes dead. I turned it off then back on and got 20 seconds of 4X?% battery then it shut off again and would not come back. Something seems to be going on to me but not sure. It is the original batter but hadn’t had problems before I did the upgrade.
