iOS 26.3 Beta 1: Everything You Need to Know Before Installing

iOS 26.3 Beta 1 Review: Features, Bugs, and Performance

Apple didn’t waste much time this round. Right after pushing out the stable iOS 26.2 update, the company quietly rolled out iOS 26.3 Beta 1 for developers. Naturally, curiosity kicked in. What’s new? What’s fixed? And more importantly, is this beta any better than the stable build most people are already using?

On paper, iOS 26.3 Beta 1 looks like a routine early beta. But once you start using it, a few interesting changes and some frustrating issues begin to show up. Let’s break it down in a simple, no-nonsense way.

Update Size and Build Changes

The iOS 26.3 Beta 1 update is not small. The download comes in at around 8.32GB when installing directly over iOS 26.2. Depending on your starting version, this may vary slightly.

The build number has changed to 23D5089 from 23C5 in iOS 26.2, signaling more beta builds to come. Storage behaves as expected: available space drops slightly, and system data increases, which usually stabilizes in later beta versions.

A Surprise Feature: Transfer to Android

One unexpected addition is a simplified Transfer to Android option in Settings under Transfer or Reset iPhone. Place both devices close together, scan a QR code, and they connect. Pairing codes or session IDs are available if scanning doesn’t work. A rare and overdue Apple move.

Notification Forwarding Gets Flexible

iOS 26.3 introduces Notification Forwarding for accessories beyond the Apple Watch, including third-party smartwatches.

• Notifications can be forwarded to only one accessory at a time
• Apple Watch notifications are disabled when forwarding is active
• Some toggles are missing in this beta

It works but feels half-baked and will likely improve in future updates.

Small Visual Tweaks

Wallpapers now separate Weather and Astronomy categories, making browsing cleaner. Fitness includes an updated splash screen and Apple Fitness+, with a one-month free trial followed by optional monthly or yearly subscriptions.

Bugs and Frustrations

The keyboard lag is noticeable, with slower typing than iOS 26.2. App closing animations are smoother on newer devices, but Clear app icons cause frame drops in App Library folders. Switching to default icons fixes this.

There’s also a weird lighting effect on some app icons while swiping, especially in Translate or Passwords. Gamers report lag when opening Control Center during gameplay.

Performance and Battery Life

Geekbench 6 scores remain almost identical to iOS 26.2. Real-world smoothness feels slightly worse, a common Beta 1 issue that often improves by Beta 3 or Beta 4.

Battery drain is slightly faster compared to iOS 26.2 stable, again expected for early beta that builds.

App performance varies too. Native apps like Mail, Messages, and Safari generally run fine, but third-party apps can behave unpredictably. Some crash or reload more often than on the current public release That inconsistency affects overall fluidity in daily use.

Should You Install iOS 26.3 Beta 1?

Short answer: no. Few new features exist, performance feels less polished, battery dips slightly, and several known bugs remain. Stability is better on iOS 26.2 stable.

Final Thoughts

iOS 26.3 Beta 1 is clearly an early testing build. Android transfer and notification forwarding are interesting, but bugs, lag, and battery issues hold it back. For most users, waiting for the stable release is the wiser choice.
