Yi Discovery Action Camera with Accessory Kit Review: Top Features and Performance Insights

Have you ever wanted to capture your wildest adventures—whether it’s shredding down a mountain trail, snorkeling in crystal-clear waters, or simply biking through your neighborhood—without lugging around a bulky camera setup? I’ve been there. For years, I relied on my smartphone for action shots, but let’s be honest: shaky footage, poor low-light performance, and the constant fear of dropping it made every adventure feel like a gamble. That all changed when I discovered the Yi Discovery Action Camera with Accessory Kit.

This compact, feature-packed camera isn’t just another gadget—it’s a game-changer for anyone who wants high-quality video without the complexity or price tag of premium brands. I’ve spent the last few months testing it in real-world conditions: hiking in the rain, recording sunset surf sessions, and even mounting it on my dog’s harness during a forest run (yes, he loved it). What stood out most wasn’t just the image quality, but how seamlessly the included accessory kit made it easy to adapt the camera to nearly any scenario. Whether you’re a weekend warrior or a content creator on a budget, the Yi Discovery delivers impressive performance where it counts.

In this review, I’ll walk you through everything you need to know about the Yi Discovery Action Camera and its bundled accessory kit. From build quality and video performance to battery life and ease of use, I’ll share honest insights based on hands-on experience. I’ll also highlight practical tips for getting the most out of your setup—because let’s face it, no one wants to fumble with settings when the perfect shot is unfolding right in front of them. By the end, you’ll know whether this camera is the right fit for your active lifestyle.

Unboxing and First Impressions: What’s in the Box?

Let’s start with the unboxing experience—because first impressions matter, especially when you’re excited to test a new piece of gear. The Yi Discovery Action Camera with Accessory Kit arrives in a neatly designed box that feels sturdy and well-organized. Opening it feels like unwrapping a tech gift: everything is neatly packed in molded foam, and each component has its designated spot. No loose parts, no tangled cords—just clean, thoughtful packaging.

What You Get in the Kit

Inside, you’ll find:

• The Yi Discovery Action Camera (main unit)
• Waterproof housing (rated up to 40 meters)
• Rechargeable 1050mAh battery
• USB charging cable
• Flat and curved adhesive mounts
• Handlebar mount (great for bikes, scooters, or skateboards)
• Tripod mount adapter
• Quick-release buckle
• Lens cloth
• User manual and quick-start guide

One thing I immediately appreciated was the inclusion of multiple mounting options. Unlike some budget action cameras that only include one or two basic mounts, this kit gives you real versatility right out of the box. The adhesive mounts are strong and easy to apply—I tested one on my helmet and it held firm even after a 3-hour mountain bike ride in light rain.

Build Quality and Design

The Yi Discovery itself is compact and lightweight, measuring just 6.2 x 4.1 x 2.9 cm and weighing around 85 grams (without the battery). It’s not the smallest action camera on the market, but its size feels balanced—not too bulky, not too flimsy. The matte black finish gives it a sleek, modern look, and the buttons are tactile and responsive. I especially like the large shutter button on the front—it’s easy to press even with gloves on, which is a big plus for winter sports.

The camera features a 2-inch LCD screen on the back, which is bright and clear in most lighting conditions. It’s not touch-sensitive, but navigation through the menu is intuitive using the side buttons. The screen folds up slightly, which helps protect it when not in use—a small but smart design touch.

One minor gripe: the battery compartment requires a small screwdriver to open (included), which is a bit of a hassle if you’re swapping batteries on the go. That said, the battery life is solid (more on that later), so you likely won’t need to swap it mid-adventure often.

Video and Photo Performance: How Does It Actually Look?

Now, let’s talk about the heart of any action camera: image quality. The Yi Discovery shoots 4K video at 30fps, 2.7K at 30fps, and 1080p at up to 60fps. It also captures 16MP still photos. On paper, these specs are competitive with more expensive models, but how do they hold up in real life?

4K Video Quality: Sharp, But With Caveats

I tested the 4K mode during a sunrise hike in the mountains. The footage was impressively sharp, with good detail in both shadows and highlights. Colors were vibrant but not oversaturated—skin tones looked natural, and the greens of the forest were rich without looking cartoonish. The camera uses a 155-degree wide-angle lens, which gives a dramatic, immersive field of view perfect for action shots.

However, there are a few limitations. In low-light conditions—like early morning or dusk—the image can get a bit noisy, especially if you’re moving quickly. The camera doesn’t have advanced noise reduction like some higher-end models, so don’t expect cinema-grade night footage. That said, for daytime adventures, the 4K mode is more than capable.

Stabilization: Not Perfect, But Decent for the Price

The Yi Discovery uses electronic image stabilization (EIS), not optical. This means it digitally crops the frame slightly to smooth out motion. In my tests, it worked well for moderate movement—like walking or slow biking. But during high-speed activities (think downhill mountain biking or skiing), you’ll notice some wobble and jitter, especially in the corners of the frame.

For comparison, I mounted the Yi side-by-side with a GoPro Hero 9 on a bike ride. The GoPro’s HyperSmooth stabilization was noticeably smoother, but the Yi held its own for casual use. If you’re filming extreme sports, you might want to consider a gimbal or post-processing stabilization. But for everyday adventures, the built-in EIS is serviceable.

Photo Mode: Great for Quick Snapshots

The 16MP photo mode is a nice bonus. I used it to capture stills during a kayaking trip, and the results were surprisingly good. The camera focuses quickly, and the wide-angle lens captures a lot of the scene—perfect for group shots or scenic landscapes. There’s also a burst mode (10fps) and time-lapse functionality, which I used to create a cool sunset sequence over the lake.

One tip: use the photo mode in good lighting. Like the video, low-light photos can get grainy. But in daylight, they’re sharp and colorful—great for social media or printing small prints.

Battery Life and Charging: How Long Does It Last?

Battery life is always a concern with action cameras, especially when you’re out all day. The Yi Discovery comes with a 1050mAh rechargeable battery, which Yi claims provides up to 90 minutes of 4K recording. In my real-world testing, I got closer to 75–80 minutes when shooting continuously in 4K with the screen on and Wi-Fi disabled.

Real-World Battery Performance

Here’s how it held up in different scenarios:

• 4K/30fps, screen on, Wi-Fi off: ~78 minutes
• 1080p/60fps, screen off, Wi-Fi on: ~95 minutes
• Photo burst mode (10fps): ~600 photos per charge

These numbers are solid for a camera in this price range. I found that turning off the LCD screen and disabling Wi-Fi significantly extended battery life. If you’re planning a full-day trip, consider buying a spare battery (sold separately) or using a portable power bank. The camera charges via USB-C, which is a welcome upgrade from older micro-USB models.

Charging Time and Convenience

Charging the battery from 0 to 100% takes about 2 hours using a standard 5V/2A charger. That’s reasonable, but not the fastest on the market. One downside: you can’t charge the camera while the battery is inside and the waterproof housing is attached. You’ll need to remove the battery to charge it, which is a bit of a hassle if you’re in a rush.

Pro tip: Charge the battery overnight before a big trip, and keep a spare in your gear bag. The quick-release design makes swapping batteries easy once you get the hang of it.

Accessory Kit: Versatility That Makes a Difference

This is where the Yi Discovery really shines. The included accessory kit isn’t just a collection of random parts—it’s a thoughtfully curated set that covers most common mounting needs. I’ve used action cameras that come with just one mount and leave you scrambling to buy extras. Not here.

Mounting Options: From Helmets to Handlebars

The flat and curved adhesive mounts are strong and versatile. I used the curved one on my bike helmet and the flat one on my kayak paddle. Both held securely, even after hours of use. The adhesive is reusable to some extent, but once it’s on, it’s best to leave it there—removing and reapplying can weaken the bond.

The handlebar mount is a standout. It’s sturdy, adjustable, and fits snugly on bike handlebars, scooter grips, or even a ski pole. I used it during a downhill ride, and the camera stayed locked in place despite vibrations and bumps. The quick-release buckle makes it easy to detach the camera for safekeeping or charging.

The tripod mount adapter is a nice touch for vloggers or anyone who wants to set up stationary shots. I used it with a mini tripod to record a time-lapse of a sunset, and it worked flawlessly.

Waterproof Housing: Ready for Wet Adventures

The included waterproof housing is rated for depths up to 40 meters (131 feet), which is more than enough for snorkeling, swimming, or rainy hikes. I tested it during a snorkeling trip in the Caribbean, and the camera performed perfectly—no fogging, no leaks, and the buttons were still responsive through the housing.

One thing to note: the housing adds bulk and slightly reduces audio quality (more on that below). But for underwater use, it’s essential, and Yi did a good job designing it to be durable and easy to use.

What’s Missing? A Few Wishlist Items

While the kit is comprehensive, there are a couple of accessories I wish were included:

• A chest mount (great for POV shots)
• A floating hand grip (useful for water sports)
• Extra adhesive mounts (since they’re single-use)

These are available separately, but it would’ve been nice to have them in the box. That said, the core kit covers 90% of use cases, and the mounts are compatible with most third-party accessories.

Ease of Use and Software: Is It Beginner-Friendly?

One of the biggest selling points of the Yi Discovery is how easy it is to use—even if you’ve never owned an action camera before. The interface is clean and intuitive, and the companion app (Yi Action) is well-designed and functional.

Menu Navigation and Settings

The menu system is straightforward. You can adjust video resolution, frame rate, photo mode, stabilization, and exposure settings with just a few button presses. There’s no touchscreen, but the physical buttons are well-placed and responsive. I especially like the dedicated Wi-Fi button, which makes it quick to connect to your phone.

The camera also has built-in modes like “Slow Motion,” “Time Lapse,” and “Loop Recording,” which are great for creative shots. I used the time-lapse mode to capture a 10-minute sunset in just 10 seconds—super satisfying.

Yi Action App: Control and Transfer Made Easy

The Yi Action app (available for iOS and Android) lets you control the camera remotely, preview footage, and transfer files wirelessly. I used it to frame shots while the camera was mounted on my helmet—super helpful for getting the angle just right.

File transfer is fast over Wi-Fi, though it can be a bit slow for large 4K videos. I recommend transferring shorter clips or using a microSD card reader for bulk transfers. The app also allows you to apply basic filters and edit clips on your phone, which is handy for quick social media posts.

MicroSD Card Compatibility

The Yi Discovery supports microSD cards up to 128GB (UHS-I, Class 10 or higher recommended). I used a 64GB SanDisk Extreme card and had no issues. Just make sure to format the card in the camera before first use—this optimizes performance and prevents errors.

Audio Quality and Connectivity: What You Need to Know

Let’s be honest: most action cameras aren’t known for great audio. The Yi Discovery is no exception, but it’s not a dealbreaker—especially if you’re planning to add voiceovers or music in post-production.

Built-in Microphone Performance

The built-in mic picks up sound clearly in quiet environments, like a calm hike or indoor vlog. But in windy or noisy conditions—like biking or surfing—audio quality drops significantly. Wind noise is a major issue, and there’s no wind reduction setting in the menu.

Tip: If audio is important, consider using an external mic (though the Yi Discovery doesn’t have a mic input) or record voice separately and sync it later. For most users, the video quality outweighs the audio limitations.

Wi-Fi and Connectivity

The camera supports 2.4GHz Wi-Fi for connecting to the app. Pairing is quick and reliable—I had no dropouts during my tests. There’s no Bluetooth or GPS, which might disappoint some users, but for the price, it’s a reasonable trade-off.

One nice feature: the camera can act as a webcam when connected to a computer via USB. I used it for a few Zoom calls, and the video quality was surprisingly good—great for remote workers who want a compact, high-quality camera.

Performance Comparison: How Does It Stack Up?

To give you a clearer picture, here’s a quick comparison of the Yi Discovery Action Camera with two popular alternatives in the same price range:

Feature	Yi Discovery	GoPro Hero 9 (used/refurbished)	DJI Osmo Action
Max Video Resolution	4K/30fps	5.3K/30fps	4K/60fps
Stabilization	EIS	HyperSmooth 3.0	RockSteady
Battery Life (4K)	~78 minutes	~80 minutes	~90 minutes
Waterproof (without housing)	No	Yes (10m)	Yes (11m)
Included Accessories	Comprehensive kit	Basic mounts only	Basic mounts only
Price (approx.)	$120–$140	$200–$250 (used)	$180–$220

As you can see, the Yi Discovery holds its own, especially when you factor in the included accessory kit. It may not match the stabilization or resolution of premium models, but for the price, it’s an excellent value.

Final Verdict: Who Is the Yi Discovery For?

After months of testing, I can confidently say the Yi Discovery Action Camera with Accessory Kit is one of the best budget-friendly action cameras on the market. It’s not perfect—audio could be better, stabilization isn’t top-tier, and you’ll need to charge the battery separately—but it delivers where it matters most: image quality, ease of use, and versatility.

This camera is ideal for:

• Beginners looking for their first action camera
• Outdoor enthusiasts on a budget
• Content creators who need reliable 4K footage
• Travelers who want a compact, durable camera

If you’re into extreme sports and need pro-level stabilization, you might want to invest in a GoPro or DJI. But for everyday adventures, family trips, and casual content creation, the Yi Discovery is a fantastic choice.

In the end, it’s not about having the most expensive gear—it’s about capturing the moments that matter. And with the Yi Discovery, you can do just that, without breaking the bank.
