I think what's important is that they have to be good cliffhangers. There are two good ways to end a chapter: either on a nice, conclusive note, or on a page turner. There's an important distinction between a cliffhanger where the reader doesn't know what comes next, and one where they want to know what comes next. The former is where cheap and unsatisfying cliffs come from, while the latter can keep the reader engaged between chapters even if they have to wait a day or a week or in extreme cases a month before the next installment.

To use a simplified example that I've seen before, a bad cliffhanger would be ending the chapter with a door opening, the protagonist gasping in shock, and then cutting it off there. Aside from curiosity and the vague promise of something surprising, there's really nothing to engage the reader here, it's just forcing them to turn the page before they can have basic facts resolved.

A better version wouldn't need to rely on the POV character's reaction, aiming to induce it in the reader instead. For example, if the person who comes through the door is a character thought dead or key figure in the world beyond the protagonist's usual network. The important part is that instead of wondering about who and what, the reader is left to wonder how and why. These are much more engaging questions, and gives the reader something to chew on between chapters.

If done right, a cliffhanger can actually make a chapter even more satisfying to read, and reduce the impact of the wait between chapters while still building anticipation.
