Today, only the huge iPhone 12 Pro Mac has this feature.
It lets you snap photos that are sharper, even in very low light.
And it may be in every iPhone 13.

Usually means improved low-light images on phone cameras."

There are two kinds of image stabilization.
One moves the lens itself, the other moves the sensor.

Both kinds have their advantages.
On a camera with interchangeable lenses, in-lens stabilization can be tailored to that particular lens.
In the end, phone cameras are already good enough for most people.

Theyre already better than the pocket film and digital cameras we all used to use.
The iPhone doesnt have such a requirement, and so IBIS is a better bet.
In-body, or sensor stabilization, only has to move a small sensor instead of a heavy lens.
Considering that it’s compensating for tiny, fast movements, the differences in momentum can be significant.
However you stabilize things, the result is the same.
you could hand-hold the camera for longer exposures, without your shaky hands introducing motion blur.
This is most useful at night or indoors, where light levels are low.
To capture more light, the camera will open its shutter for a longer time.
If you move while its open, then normally you blur the picture.
Not Just Low Light
Stabilization isnt just handy for low-light shots.
You also can use a slower shutter speed for special effects in regular light.
The cliche here is a picture of moving water, a fast-flowing river or a waterfall.
you’re free to use a longer shutter speed to blur the water.
Another nice example is a portrait taken in a busy street.
you might allow the surrounding people to blur, while your non-moving subject stays sharp.
This can look great.
High-end mirrorless cameras do have a lot of computer power on board, but it is specialized image-processing hardware.
Phones are general-purpose computers, and can, of course, run apps that take advantage of their hardware.
And, in the end, phone cameras are already good enough for most people.
Theyre already better than the pocket film and digital cameras we all used to use.
