Apple finally did it. After years of iterative changes that felt like moving furniture around the same living room, the iOS 26 developer beta just dropped, and it’s basically a sledgehammer to the status quo. If you’ve been hanging onto your iPhone because you didn't see a reason to care about "incremental improvements," the 26.3 build might be the one that actually makes you look at your screen differently.
Honestly, the biggest shock isn't even the AI features, though we’ll get to those. It’s the eyes. Or rather, what the eyes see.
Apple has moved away from the flat, matte look that’s dominated since iOS 7. They’re calling the new design language Liquid Glass. It’s part of a project internally known as "Solarium," and it looks exactly like what happens when you take the transparency of visionOS and melt it into a smartphone. Your icons aren't just pictures anymore; they’re translucent, reactive little tiles that seem to refract the light from your wallpaper.
The iOS 26 Developer Beta Is Not Just for Devs Anymore
Let’s be real: most people downloading the developer beta aren't actually coding apps. They just want the new stuff first. And with the 26.3 beta 2 specifically, Apple is fixing some of the biggest headaches that have plagued the initial September release.
One of the weirdest—but coolest—additions is a tool that helps you move from an iPhone to an Android device without a third-party app. Yeah, you read that right. Apple is actually making it easier to leave. It’s a move likely driven by EU regulations, but seeing it in the settings menu feels like a "hell freezes over" moment.
What’s actually in the 26.3 build?
If you’re running the iOS 26 developer beta right now, you’ve probably noticed the new "Adaptive Power" mode. Unlike the old Low Power Mode that basically neutered your phone, Adaptive Power uses the on-device "Apple Intelligence" to figure out what you’re doing. If you’re just scrolling Reddit, it throttles the chip way down. But if you suddenly open the camera, it ramps back up instantly. No lag. No stutter. It’s smart.

The feature list is getting long, so here’s the breakdown of what actually matters in your day-to-day:
- Notification Forwarding: If you live in the EU and use a non-Apple smartwatch, your notifications will finally play nice.
- Weather Wallpaper: It’s been tweaked to be more "liquid." The clouds actually look like they’re floating behind your widgets.
- The "Clear" Theme: You can now make your home screen icons almost entirely transparent. It’s a minimalist's dream, but it's kinda hard to see if your wallpaper is busy.
- RCS Encryption: 26.3 is finally laying the groundwork for end-to-end encryption on RCS messages when texting your Android friends.
Siri is basically Google Gemini now (Mostly)
We’ve been hearing about the "New Siri" for ages. Apple finally confirmed that Google Gemini is powering the heavy lifting for the next-gen assistant. In the current developer beta, you can see the early stages of this. Siri isn't just a voice that fails to set timers anymore; it actually understands what’s on your screen.
If you’re looking at a photo of a restaurant in a text thread, you can just say, "How long does it take to get there?" and it knows exactly what "there" is. It doesn't need you to copy-paste the address.
According to Mark Gurman at Bloomberg, the full-fat version of this revamped Siri is targeted for the iOS 26.4 update in the spring of 2026. But the beta 26.3 build is where the plumbing is being installed. It’s faster. It’s more conversational. And it doesn't get confused if you stumble over your words.
Is your iPhone too old for this?
This is the part that sucks. If you're rocking an iPhone XS, XR, or anything older, you’re officially at the end of the road. iOS 26 requires the A13 Bionic chip or newer.
Basically, you need an iPhone 11 or later to even get in the door. And if you want the "Apple Intelligence" stuff? You better have an iPhone 15 Pro or any model in the iPhone 16 or 17 lineup. Apple is being very strict about the 8GB RAM requirement for the AI models.
How to get the beta without breaking your phone
If you’re brave enough to install the iOS 26 developer beta, don't just dive in. Back up your stuff. Seriously. This is beta software; it has bugs. Your bank app might crash. Your battery might drain in four hours.

- Register: Go to the Apple Developer website and sign in with your Apple ID.
- Toggle the Switch: Head to Settings > General > Software Update > Beta Updates.
- Choose 26 Developer Beta: It should pop up right there.
- Wait: It’s a huge download. Make sure you’re on Wi-Fi and plugged into a charger.
Honestly, if this is your only phone, you might want to wait for the public beta. It’s usually a week behind the developer version but significantly more stable.
The verdict so far
iOS 26 feels like Apple is finally embracing the future instead of just polishing the past. The Liquid Glass design is stunning, and the integration of Google Gemini into Siri makes the "smart" part of your smartphone actually feel smart.
Actionable Next Steps:
Check your storage before you download. The iOS 26 developer beta is heavy, and you’ll need at least 15GB of free space for the installation to go smoothly. If you’re an app developer, start looking at the new "Foundation Models" framework in Xcode 26 to see how you can hook your own apps into the new Siri onscreen awareness. If you're just a regular user, maybe wait for the 26.3 public release at the end of January to avoid the "my-phone-is-now-a-brick" syndrome.
