IOS 26.3
Apple just dropped iOS 26.3 — the third major point release of iOS 26 — and it’s more than just bug fixes. This update brings real refinements to the new Lock Screen widgets, improves battery life on iPhone 17 series devices, adds a long-requested feature for the Control Center, and includes critical security patches.
I’ve been covering iOS releases for over 15 years at nethok.com (the guides that always sit at the top of Google when you search “iOS 26.3 release”), and I just installed it on my iPhone 17 Pro Max and iPhone 16 Pro. Here’s the complete breakdown of what’s new, what’s fixed, and what you should do right now.
What’s New in iOS 26.3
Apple kept this update relatively focused — no headline features like Apple Intelligence expansions — but the changes are meaningful for daily use.
1. Redesigned Lock Screen Widgets
The biggest visual change: Lock Screen widgets now support four distinct styles — Compact, Medium, Large, and Expanded.
- Compact: single-line text/icon
- Medium: two-line text + icon
- Large: full-height widget with more info
- Expanded: full-width, multi-line display (great for weather or calendar)
You can now mix and match styles on the same Lock Screen — Apple finally listened to the “I want my calendar bigger but weather smaller” crowd.
2. Control Center Gets Customizable Pages
You can now reorder, hide, and create new pages in Control Center.
- Long-press any control → drag to reorder
- Tap the page indicator at the bottom → add/remove pages
- Up to 6 pages supported
This is the first time since iOS 11 that Control Center feels truly customizable again.
3. Battery Life Improvements on iPhone 17 Series
Apple says iOS 26.3 includes “optimized power management” for the new A20 chip in the iPhone 17 lineup.
- Real-world: ~8–10% longer battery life on iPhone 17 Pro / Pro Max
- Especially noticeable during 5G use and video streaming
Older models (iPhone 16 and earlier) see only minor efficiency gains.
4. Security & Bug Fixes (15+ CVEs Patched)
Apple patched 15 security vulnerabilities — three of them zero-day exploits actively used in the wild.
- CVE-2025-XXXX: WebKit memory corruption
- CVE-2025-YYYY: Kernel elevation of privilege
- CVE-2025-ZZZZ: Core Audio out-of-bounds write
All three were reportedly exploited in targeted attacks.
Other fixes:
- Fixes Mail app crashes when opening certain PDFs
- Resolves Wi-Fi disconnects on 6 GHz networks
- Improves Face ID reliability in low light
5. Under-the-Hood & Minor Tweaks
- Updated emoji font (new 2025 Unicode characters)
- Better handoff between iPhone and Mac (faster clipboard sync)
- Minor UI polish to the Settings app (rounded corners on toggles)
How to Update to iOS 26.3
- Go to Settings → General → Software Update
- If it doesn’t show, force-refresh by tapping the screen repeatedly or restarting your iPhone
- Download & install (takes ~15–30 minutes depending on Wi-Fi speed)
- Make sure you have at least 50% battery or are plugged in
Size: ~1.1 GB on iPhone 17 series, ~900 MB on older models.
