iPhone 7 iOS 12 Beta 2: Impressions & Performance

Share on FacebookPin on PinterestShare on StumbleUponTweet about this on TwitterShare on LinkedIn

Apple’s pushed out iOS 12 beta 2 to those participating in the Beta Software Program. The Beta Software Program is free to anyone with an Apple ID.

The iOS 11.4 update has been treating my iPhone 7 pretty well, but I decided to hop off iOS 11 in order to test iOS 12’s performance. I’ve been hearing great things about iOS 12’s performance.

So far I’m really enjoying iOS 12’s features and its performance on my device thus far has been pretty solid. That said, this is beta software and it does have its fair share of issues. I’ve already encountered several during my time with the software.

The second beta is performing a little better, but there’s one issue that might force me to drop my device back to iOS 11.4.

If you’re thinking about trying the iOS 12 beta allow me to take you through my brief impressions of the latest version’s performance on the iPhone 7.

iPhone 7 iOS 12 Beta Installation

Before I get into the key areas performance, a few notes about the iOS 12 beta installation.

Prior to running iOS 12 beta my iPhone 7 was running iOS 11.4, the most up-to-date version of iOS 11. That said, I was still forced to download a 2GB+ file.

After spending several minutes preparing the download, it took just about three minutes to pull the iOS 12 beta file from Apple. The installation took a lot longer.

It took around 13 minutes for iOS 12 beta to install on my iPhone 7. That’s much longer than your standard iOS update. The device rebooted once toward the end of the installation so if that happens (or happened) on your device, there’s no need to be alarmed.

I haven’t seen too many complaints about iOS 12 installation issues, but there’s always a chance your download gets stuck or you encounter an error.

If this is your first time installing iOS beta software please take a look at our iOS 12 beta download guide. It should help you get through the process problem-free.

If you’re moving from iOS 12 beta 1 to iOS 12 beta 2, you can expect a 560MB download. The update took about 5 minutes to download and prepare while the installation took another five minutes to complete.

Battery Life

I’ve only been using iOS 12 beta 2 for a short time so I can’t share anything about long-term battery life just yet. What I can tell you is that short-term battery life is strong and I haven’t noticed any abnormal drain. It appears normal.

I’ve been using a mixture of Wi-Fi and cellular data and I’ve been able to go about my typical day answering emails, browsing the web, answering Slack messages, and making phone calls. I haven’t noticed much of a difference between iOS 12 beta 1 and iOS 12 beta 2.

I haven’t noticed any issues, but some users are running into battery life problems while running iOS 12 beta.

If you can’t find a manual fix for your battery issue, you’ll want to downgrade back to iOS 11.


Connectivity can sometimes take a turn for the worst on beta software, but I haven’t seen any issues with the iPhone 7’s various connections.

I’ve been able to connect to various routers including eero mesh Wi-Fi without any trouble. Those connections are stable and fast.

I’ve also been able to connect our device to several different Bluetooth devices including speakers and headphones. Everything is functioning like it did on iOS 11.

I’ve heard some rumblings about GPS issues, but I haven’t noticed any yet. My iPhone 7 was able to pinpoint and track my exact location.

Cellular data is also working normally. I’ve been able to connect the iPhone 7 to AT&T’s LTE and 4G networks with ease.

Apps & Services

One of my biggest gripes with pre-release iOS software is that it tends to conflict with far too many applications. I typically see an uptick in crashes, bugs, and other performance issues. And it’s these issues that usually drive me to downgrade.

The good news is that iOS 12 feels more stable than some of Apple’s iOS 11 betas, but I’ve still run into issues with my apps and services.

Apps like Chrome, Gmail, and Spotify have all crashed during my time on the latest beta. Other core apps like Slack, Twitter, Soundcloud, and The Weather Channel are performing just fine.

I’ve only been using iOS 12 beta 2 for a short time so there’s a chance performance evens out. There’s also a chance these problems plague me throughout my time on this version of the iOS 12 beta.

At this point, app performance is too unpredictable. If you rely on the apps on your phone to get you through the day, you might want to stick around on iOS 11.


This is where iOS 12 beta truly excels.

iOS 11.4 was fairly speedy on my iPhone 7, but iOS 12 absolutely flies. This comes as no surprise given the performance improvements Apple’s promised in iOS 12.

If you recall, Apple says the iPhone 5s will open apps 40% faster, swipe to the camera from the lock screen 70% faster, show the keyboard faster, and deliver better all-around performance. And it’s not just fossils like the iPhone 5s that benefit. Newer devices like the iPhone 7 do as well.

Animations are fast and fluid, transitions are crisp, and I haven’t noticed any lag when pulling Control Center and Notifications open. I’ve seen a bit of keyboard lag, but that’s the only slow down I’ve seen during my time on the software.

Unfortunately, my iPhone 7 randomly rebooted itself shortly after I moved to the iOS 12 beta 2. That’s a red flag and something I’ll keep an eye on as we push away from the release.

Should You Install the iPhone 7 iOS 12 Beta?

iOS 12 beta 2 feels a lot like beta 1 and I haven’t seen any drastic changes in performance. If you’re currently running the first beta, you’ll want to install beta 2 because it comes with enhancements and important bug fixes.

There are some great reasons to give iOS 12 a spin on your iPhone 7 or iPhone 7 Plus. There are also a few reasons why you might want to wait for an upcoming beta or for the final iOS 12 release this fall:

  • Speed.
  • Lots of new features.
  • Strong battery life.
  • Easy to install.
  • Potential for poor app performance.
  • Potential for crashes.
