The iOS 27 public beta is out. Here's what's new and whether you should install it

Apple flipped the switch on the first public betas of iOS 27 and iPadOS 27 this week, which means you no longer need a developer account to try the biggest iPhone update of the year. I've been living with it, and it's a genuinely exciting release, and most of you should still probably wait a little longer to put it on your main phone. Let me explain both halves of that.

The public beta landed on Monday, July 13, alongside betas for macOS 27 Golden Gate, watchOS 27, visionOS 27, and tvOS 27.

If you want in, you sign up for free at beta.apple.com, then head to Settings, General, Software Update, and pick iOS 27 Public Beta under Beta Updates. This build is identical to the third developer beta, so it's a few rounds into testing rather than a raw first draft. iOS 27 works on every iPhone that runs iOS 26, going all the way back to the iPhone 11.

Siri finally grows up

The reason most people care about iOS 27 at all is Siri AI, and it deserves the attention.

This is the rebuild Apple has been promising for what feels like forever. Instead of firing off one command at a time, the new Siri holds an actual conversation, remembers what you just asked, and can look at what's on your screen to figure out what you mean.

It can search the web, pull from your own messages, emails, photos, and notes, and take actions across apps. There's a dedicated Siri app now that keeps a history of your chats and syncs across your devices through iCloud, and Siri lives in the Dynamic Island, expanding into a "Search or Ask" bar when you summon it. If you've used ChatGPT or Claude, the shape of it will feel familiar.

What excites me most is how it handles context.

In my testing, telling Siri to go back to a note I'd dictated earlier and add a detail just worked. It found the right note, updated it, and cleaned up the formatting without me spelling out every step. That's the kind of thing old Siri would have face-planted on.

That said, there's a catch worth knowing before you rush in.

Siri AI sits behind a waitlist, the same way Apple Intelligence did back in 2024. After you install iOS 27, you request access and then wait, sometimes a few hours, sometimes a few days. It also only runs on Apple Intelligence capable hardware, which means iPhone 15 Pro or newer. So if you're updating purely to talk to the new Siri, temper your expectations. You might be staring at a waitlist for a bit.

It's not just Siri

I keep seeing iOS 27 described as an AI update, and that undersells it. Some of my favorite changes have nothing to do with Siri.

Safari can now organize your open tabs into topic groups on its own, which is a small mercy if you're the kind of person who ends the day with forty tabs open.

There's a new Notify Me feature that watches a webpage for changes, so you can point it at a sold out product and let it ping you on a restock instead of refreshing all day. You can even describe a Safari extension in plain language and have it built for you (one of my favorite features).

Photos picks up three editing tools, an upgraded Clean Up that handles messier backgrounds, an Extend tool that fills in the area around a cropped shot, and Spatial Reframing, which borrows technology from Vision Pro to shift the apparent angle of a photo after you've already taken it. Apple's pitch for that last one is bold, so I'd treat it with healthy curiosity until it's been run through enough real photos.

Elsewhere, the Passwords app can now swap out weak or compromised passwords for you, Shortcuts lets you build automations by just describing what you want, and Screen Time got a top to bottom overhaul aimed squarely at parents. That last one is a bigger deal than it sounds. There are category based Time Allowances for things like games and social media, per app schedules, and an Ask to Browse control that requires a kid to get approval before visiting a new website.

The fixes might matter more than the features

If I'm honest, the part of iOS 27 I've come to appreciate most isn't a feature at all. It's the polish.

Apple optimized the CPU scheduler on every supported iPhone, back to the iPhone 11, and you can feel it. Unlocking, moving around the Home Screen, and scrolling Control Center all feel smoother, the camera opens faster in Low Power Mode, and your phone is smarter about jumping between Wi-Fi and cellular instead of clinging to a dead network as you walk out the door. Search across Spotlight, Photos, and Mail got rebuilt too.

The other quiet fix is Liquid Glass.

Last year's design overhaul got a lot of grief for being hard to read, and iOS 27 answers that directly with readability improvements and a slider that lets you dial the effect back toward something more opaque.

Bloomberg's Mark Gurman has framed this whole release as a "Snow Leopard update" focus on reliability over flash, system performance over new features, and after using it, that comparison feels earned. It's worth noting that this is a rare year where the boring stuff is the selling point.

So, should you install it?

You should expect the occasional crash, some unexpected battery drain, and a few apps that misbehave.

The usual suspects are banking apps, authentication apps, VPN clients, smart home tools, and business software, none of which get full iOS 27 support until the real release this fall.

Before you do anything, ask yourself which apps you genuinely can't lose for a couple of weeks and be ready for the update treadmill, because Apple ships fresh betas roughly every two weeks.

If you decide to jump in, back up first, and do it properly.

An archived local backup on your Mac or PC is the safe move, because unlike an iCloud backup it won't get overwritten with iOS 27 data. That archived copy is your escape hatch back to iOS 26 without losing everything.

If you've got a spare iPhone or iPad, or you're comfortable troubleshooting the occasional bug for early access, this is a great year to try the beta. But if you're carrying one phone that you rely on for work, or you're about to travel, do yourself a favor and wait for the finished version in September, which should arrive alongside the iPhone 18 lineup.

The public beta is a real look at where your iPhone is headed. Just remember that by installing it, you're also signing up to help Apple finish building it.
