Now that Apple has unveiled the iOS 27 beta, it’s tempting to rush out and download it. Since you don’t even need a paid developer account to get the Developer Beta, there’s nothing but a couple minutes of filling out forms standing between you and an early look at the big iOS update coming this fall.
But before you start that download, I’m here to remind you of the beta software always carries some risk, and early iOS betas especially so.
A positive word about installing the iOS 27 Beta
The iOS 27 beta has a lot of the new features, including an updated version of Siri with a ‌Siri‌ app and new AI features for apps like Photos, Camera, and Wallet.
If you decide to install the iOS 27 beta, I recommend doing it on a separate iPhone that isn’t used as your main personal phone. iOS 27 will work with models as old as the iPhone SE (second generation) and iPhone 11, so reach into the back of your tech drawer and put that forgotten iPhone into service.
Also, as always, make sure you have good backups of your data.
Bugs are part of the iOS 27 beta
Now, let’s discuss why updating to the iOS 27 beta might be a bad idea.
Software bugs at the development stage are to be expected — in fact, that’s kinda the point. Now is the time for bugs to skitter into the light so developers can catch them and Apple can fix them before the final release.
Bugs can vary across the spectrum. You could face connectivity issues with Bluetooth or Wi-Fi, or end up with third-party applications crashing from time to time. Features that work perfectly on iOS 18 might not be up to par on iOS 27, even if they aren’t necessarily tied to new iOS 27 features. And runaway background processes could keep the system running hotter than normal, decreasing not just how long the phone operates on a battery charge, but potentially stressing the battery’s lifespan. To be fair, I’ve never dealt with any show-stopping, brick-your-phone bugs in a beta — usually, they’re a series of annoyances that can grate on you after a while. But all of this is perfectly normal in developer and betas.
But if you don’t want to deal with bugs and other issues that could make your phone more difficult to use, you probably don’t want to install iOS 27 beta on your primary iPhone.
Your battery life may worsen
Did you recently buy a portable charger for your iPhone? Expect to make more use of it while running beta software. Energy efficiency is usually the last thing Apple’s developers optimize, because the priority at this point is to make sure features work and bugs are stamped out.
An iOS update also triggers a host of internal indexing, which consumes a lot of energy for a few hours or days after installation. The Photos app, for example, updates its database of recognized people, scans images for new recognizable objects or scenes for search purposes and looks for duplicates.
Performance may take a hit
Partially because of the reindexing of gigabytes of data on your phone, the iOS 27 beta will almost certainly not deliver the performance you might be expecting. Processor-intensive apps and games also need to be tuned to work with the new iOS, so stutters and glitches are normal.
You don’t really need to use the iOS 27 beta right now unless you’re a developer who really needs to start testing your app or updating it to use new frameworks and APIs.
