Insta360 X4 Review: The AI 360 Camera That Finally Does It All

The Insta360 X4 has been the 360 camera of choice for UK creators, cyclists and adventurers for well over a year, and in 2026 it still feels like the camera that every rival is trying to catch. It takes the invisible-selfie-stick magic of the X3, bumps resolution to a proper 8K, doubles the battery to 135 minutes, adds replaceable lens guards, and crucially leans harder than ever into AI for both shooting and editing.

After a month of testing around the UK — cycling the South Downs, kayaking in Cornwall, and filming some unintentionally dramatic dog walks in the Lake District — here is our honest verdict.

Quick Verdict

What Is the Insta360 X4 Actually For?

The X4 is a dual-lens 360 action camera. Instead of pointing it at your subject, you just hit record and capture everything around you — sky, ground, rider, passenger, terrain — in one continuous spherical shot. Afterwards, you use the Insta360 app (or Studio desktop software) to reframe the footage into a conventional flat video, deciding your shot after the fact rather than before.

It is the same concept as the X3, but with three genuine generational upgrades:

• A new 5nm AI chip that enables sharper 8K 360 capture and faster in-app processing
• Replaceable lens guards — a small change that utterly transforms the X4's long-term durability
• Meaningfully better battery life, from around 80 minutes on the X3 to roughly 135 minutes in the same 5.7K mode

For anyone who has ever felt the lurch of dropping a 360 camera lens-first on tarmac, that second one alone justifies the upgrade.

Image Quality: The 8K Difference Is Real

360 video has always had a resolution problem. When you film in 360 and then crop down to a standard 16:9 rectangle, you are discarding roughly 75% of the pixels. That means a 5.7K 360 source only really delivers about 1080p quality in the reframed output — fine for social media, underwhelming on a big screen.

The Insta360 X4 shoots 8K at 30fps and 5.7K at 60fps. Reframed 8K footage now genuinely holds up at 4K on a television, and side-by-side with the X3 it is no contest: sharper edges, less compression mush, and a bigger dynamic range thanks to the new Active HDR mode.

Low-light footage is also clearly improved, which matters in the UK where golden hour happens at 4pm in winter. Noise is better controlled and the colour science feels more neutral out of the camera. It is still not going to replace a mirrorless at night, but for an action cam the jump is substantial.

For a traditional flat action cam, GoPro's Hero 12 Black still has the edge in single-lens image quality. If action camera image quality is your absolute top priority, have a look at our GoPro Hero 12 Black review for a direct comparison.

AI Features: Where the X4 Really Earns Its Keep

The X4 is marketed as AI-powered, and unlike a lot of buzzword-bingo product launches, this is actually where it pulls away from the field.

AI Reframing — You film a 90-second bike ride, load it into the Insta360 app, and tap "Shot Lab". The app identifies your face, your bike, the horizon and the most interesting subjects, then automatically creates a reframed clip that pans from third-person to first-person to drone-like overhead without you touching a keyframe. In testing, roughly seven out of ten auto-reframes were good enough to post straight to Instagram with no further tweaking.

Deep Track 3.0 — In single-lens mode, the X4 uses AI subject tracking to keep a person, pet or vehicle centred in frame even when they move rapidly. It is not flawless — it lost a running collie against a busy background — but in 4K single-lens mode it is a huge step up from the X3.

AI Warp — A creative effect that adds motion-matched speed ramps using AI to detect movement. Gimmicky in bad hands, genuinely cinematic with a bit of thought.

AI Gesture Control — Hold up an open palm, and the camera starts recording; make a "V" sign, and it takes a photo. Useful if you are gloved up on a ski slope or holding handlebars.

Stabilisation: FlowState Is Still Industry-Leading

Insta360's FlowState stabilisation combined with 360 capture produces an unusual result: stabilisation becomes effectively free, because 360 footage already contains every angle. The software simply picks the smoothest horizon-locked path through the data. In practice, footage from pothole-ridden British back roads looks as smooth as anything a gimbal would produce.

A dedicated Horizon Lock toggle keeps the horizon level even when the camera tilts fully upside-down — useful for motorcycling and mountain biking where the camera gets knocked around constantly.

Battery and Memory

Battery life is one of the quieter but most consequential upgrades. Where the X3 routinely needed a spare battery for anything longer than an hour, the X4's 135-minute runtime (rated at 5.7K) will comfortably cover a morning's cycling or a half-day's family hike. Our real-world test at 8K/30fps returned just over 90 minutes, which is still excellent for the resolution.

The X4 uses microSD cards. We recommend a V30-rated 256GB card minimum; 8K footage eats storage quickly. USB-C fast charging takes the battery from flat to 80% in around 20 minutes.

Waterproofing and Durability

10m of native waterproofing — no housing required — makes the X4 ideal for British summers, which can turn torrential without warning. It handles splashes, rain, snow and shallow swimming pools without fuss.

The star of the durability story, though, is the replaceable lens guard system. Because the X4's lenses protrude, they have always been the weak point of the X series. A single knee-high drop onto a pavement could scratch a lens and ruin the camera. The X4's lens guards unscrew and can be swapped in under a minute with a replacement costing around £20 rather than £500. It is not exciting, but it is easily the most important practical upgrade on the camera.

How Does It Compare to a Drone?

This is the question we get most often. 360 cameras can create drone-like virtual camera moves on a selfie stick, giving the illusion of a camera flying above or around you. The effect is genuinely impressive — especially when combined with AI reframing.

But a 360 camera cannot actually fly. If you want real aerial footage of the Scottish Highlands, a proper drone will always beat a 360 camera. Our DJI Mini 4 Pro review covers that side of things, and for a full shortlist see our best camera drones for adults roundup. That said, the X4 is infinitely more portable, legal in places drones are not, and costs less than a midrange drone. Most serious creators end up owning both — the X4 for close-in action, the drone for landscape work.

The Insta360 App: Love It or Leave It

The Insta360 app is where most of the X4's magic happens, and it is a genuinely excellent piece of software. AI reframing, auto-editing templates, music syncing, LUT import and social export are all built in.

It can, however, be overwhelming. There are dozens of templates, sub-menus and Shot Lab effects, and first-time 360 users are likely to spend their first weekend lost in it. Once you understand the basic "capture first, frame later" workflow, it gets much easier — but budget for a learning curve.

A more serious issue: 8K editing requires a reasonably modern phone or PC. An iPhone 13 or newer, a Samsung Galaxy S22 or newer, or an M-series Mac will handle it smoothly. Older Android devices will struggle, particularly for longer clips.

Who Should Buy the Insta360 X4?

Perfect for:

• Cyclists, motorcyclists and e-scooter riders who want automatic third-person angles
• Travel vloggers who want one camera to cover every angle
• Skiers, snowboarders and watersports enthusiasts
• Any content creator tired of missing the shot
• Drone owners who want complementary close-up coverage

Consider alternatives if:

• You only ever film stable, single-angle content (a GoPro or a mirrorless will serve you better)
• Your phone or laptop is more than five years old
• You want the cheapest entry to 360 (the older Insta360 X3 is heavily discounted and still capable)

Value for Money

At around £449-£549 on Amazon UK depending on bundle, the X4 sits between a premium action cam and an entry-level drone. That is not cheap, but nothing else in 2026 gives you 8K 360 capture, AI reframing, 135-minute battery life and replaceable lens guards in a single package.

For occasional use the X3 is still a sensible buy at about £100 less. For anyone serious about content creation, adventure sports or travel vlogging, the X4 pays for itself fast in editing time saved alone.

Amazon UK pricing fluctuates — we would not claim it is always the cheapest — but it is usually where you will find the fastest delivery and the easiest returns if the camera is not for you.

Pros and Cons Summary

What we love

• 8K 360 capture genuinely outperforms the X3 and every current rival
• AI reframing and auto-edits remove the single biggest barrier to 360 creation
• 135-minute battery life is best-in-class for action cameras
• Replaceable lens guards finally address the X-series' biggest weakness
• Invisible selfie-stick trick is still the most talked-about feature with non-techy viewers

What could be better

• 8K editing can stress older phones and laptops
• Single-lens mode is decent but GoPro Hero 12 still wins for pure flat 4K
• The app's feature list can overwhelm beginners

Final Verdict

The Insta360 X4 is the most capable consumer 360 camera you can buy in 2026 and, for many creators, the most capable action camera of any kind. The combination of 8K resolution, AI-powered reframing, improved battery life and replaceable lens guards makes this the first X-series model that feels genuinely finished rather than iteratively improved.

If you want drone-like shots, invisible-selfie-stick magic, and the freedom to frame your shot after you have already lived the moment, nothing else comes close right now.

Rating: 4.6/5 — The benchmark 360 action camera of 2026.
