If you’ve ever tried to photograph your pet running or capture someone jumping in the air and ended up with a blurry mess, high speed mode in phone cameras is designed exactly for that. This mode, which more and more manufacturers are incorporating into their devices, lets you capture extremely fast movement with a sharpness that regular camera mode simply can’t achieve.
In this article, I’ll explain in detail what high speed mode is, how it works technically, and when you should actually use it.

What exactly is high speed mode?
High speed mode is a camera feature that dramatically increases capture speed, whether in photography or video. In photography, this translates to a very high shutter speed (for example, 1/4000 of a second or faster), which freezes motion. In video, it means recording at more frames per second (fps) than normal to create slow-motion effects.
It’s worth noting that not all phones call it the same thing. Samsung uses “Super slow-mo recording,” Apple refers to “Slo-mo” at 240 fps or higher, and Xiaomi calls it “Sports mode” on some models. But the principle is the same: capturing fast movement without losing quality.
Personally, I think this mode is one of the most underrated features of modern phone cameras. People obsess over megapixels and night mode, but rarely think about capture speed, which for certain types of photography is actually much more important.
Pro-tip: Before using high speed mode, make sure you have good lighting. When shooting at such high speeds, the sensor receives much less light, so you need a well-lit environment or your photo will come out dark or very noisy.
How high speed mode works technically
To understand why high speed mode produces better results in movement situations, you need to know a bit about how the camera sensor works.
Shutter speed in photography
Shutter speed determines how long the sensor’s shutter stays open. In a normal photo, this time might be 1/100 to 1/500 of a second. In high speed mode, the shutter opens for much smaller fractions, like 1/2000 or 1/8000 of a second.
The faster the shutter closes, the less movement the sensor registers. That’s why moving objects appear sharp and without blur. The problem is, by reducing exposure time so much, very little light enters, so the system needs to compensate with higher ISO or wider apertures.
Frames per second in video
In video, high speed mode means recording at more frames per second. Normal video is shot at 30 or 60 fps. High speed mode can reach 120, 240, 480, or even 960 fps on some premium models.
When you play back a video recorded at 960 fps at normal speed (30 fps), each real second of video becomes 32 seconds of slow motion. This lets you see details the human eye can’t perceive, like a water droplet’s impact or a balloon popping.
Computational processing
Modern phones don’t rely solely on the sensor hardware. They use computational processing to improve photos in high speed mode. This includes noise reduction algorithms, frame stacking, and automatic exposure adjustment.
When to use high speed mode on your phone
High speed mode isn’t for everything. Using it when it’s not necessary can produce worse results than auto mode. Here are the scenarios where it truly makes a difference:
| Situation | High speed mode? | Reason |
|---|---|---|
| Action sports | Yes, essential | Freezes fast movement |
| Running pets | Yes | Prevents animal blur |
| Playing children | Yes | Captures expressions and jumps |
| Fireworks | Yes for video | Spectacular slow motion |
| Static landscapes | No, unnecessary | Normal mode is better |
| Portraits | No, unnecessary | High speed adds nothing |
| Food photography | No, unnecessary | Better use portrait or auto mode |
| Night photography | No, counterproductive | High speed mode makes everything worse in low light |
The general rule I use is simple: if the subject moves and I want to capture that movement clearly, I activate high speed mode. If the subject is still or the scene has no significant movement, I use normal or auto mode.
How to activate high speed mode on popular phones
Each manufacturer implements high speed mode differently. Here’s how to find it on the most popular phones:
Samsung Galaxy
Open the camera and swipe to the “More” tab. Look for “Super slow-mo” or “Pro video.” On recent models like the Galaxy S24, you can also find shutter speed options in Pro mode.
iPhone
Open the camera and select “Slo-mo” in the mode bar. On the iPhone 15 and later, you can record at 240 fps in 1080p. For photos, use Burst mode by holding down the shutter button.
Xiaomi / Redmi
Open the camera, go to “More” and select “Slow motion” or “Sports.” Some Xiaomi models allow up to 960 fps in slow motion.
Google Pixel
In Camera mode, select “Slow motion” or use “Action” mode, which optimizes capture for moving subjects. Pixels rely heavily on computational processing to improve these shots.
Warning: Don’t confuse high speed mode with burst mode. Burst takes many photos in a row at normal speed. High speed mode takes each individual photo at a very high shutter speed. They’re different things with different purposes.
Comparison: high speed mode vs normal mode
To make it clearer when to use each mode, here’s a direct comparison:
| Feature | Normal mode | High speed mode |
|---|---|---|
| Shutter speed | 1/60 - 1/500s | 1/1000 - 1/8000s |
| Light intake | Optimal | Reduced |
| Motion freezing | Limited | Total |
| Image noise | Low | Can be high |
| Best for | Static scenes | Fast movement |
| Battery consumption | Normal | Higher |
| Disk space | Normal | Larger (more data) |
As you can see, high speed mode has clear advantages for movement but sacrifices light and generates more noise. It’s a balance the photographer needs to understand to get the most out of it.
Tips to get the most out of high speed mode
If you want to improve your photos and videos with this mode, here are some tips I’ve learned through practice:
-
Find good lighting. It’s the most important factor. Outdoors during the day is the perfect scenario. Indoors, get close to windows or use strong artificial lighting.
-
Stabilize your phone. Even though you’re capturing movement, your hand should be as still as possible. A mini tripod or resting your elbow on something stable helps a lot.
-
Anticipate the moment. In high speed mode, shutter lag can make you late. Practice anticipation: start shooting or recording just before the action happens.
-
Don’t overuse zoom. Digital zoom reduces image quality, and combined with the already demanding high speed mode, the result can be disappointing. Get physically closer if possible.
-
Edit afterward. Many times, photos in high speed mode need exposure and contrast adjustments in post-processing. Apps like Snapseed or Lightroom Mobile are perfect for this.
FAQ: Frequently asked questions
Does high speed mode drain more battery?
Yes, significantly. The sensor works faster and the processor does more calculations per second. If you’re planning a long shoot, bring a portable charger.
Can you use high speed mode in low light?
Technically yes, but the results will be mediocre. The sensor needs a lot of light to compensate for the very high shutter speed. In low light, you’ll see a lot of noise and darkness.
What’s the difference between 120 fps and 240 fps?
The difference is in how much slow motion you can get. At 120 fps, playing back at 30 fps gives you 4x slow motion. At 240 fps, you get 8x. More fps means a slower final result.
Does high speed mode work for selfies?
It works, but it’s not ideal. Front cameras usually have lower-quality sensors than rear cameras, so performance in high speed mode will be inferior.
Conclusion
High speed mode in phone cameras is a powerful tool when used correctly. It lets you capture movement with impressive sharpness and create slow-motion effects that were previously only possible with professional cameras.
The key is understanding when to use it: in situations with fast movement and good lighting. For everything else, auto or normal mode will give you better results. Try it next time you see your kids playing or your dog running in the park, and you’ll notice the difference.
