If you're wondering why your vape isn’t working like it used to, it might be empty. This happens to all vapes, even top models like the Hayati Pro Ultra 15000. The good news is that there are clear signs you can look for. Once you know what to check, it’s easy to figure out if your device is finished or just needs a small fix.

Let’s walk through the signs that your vape might be out of liquid or nearing the end of its life.

Weak or No Vapor Production

When your vape is full and working right, it makes smooth clouds of vapour. If you start taking puffs and nothing happens—or you get very little vapour—your device might be empty. A weak hit or thin cloud means the coil may no longer have any liquid to heat up. This is usually the first sign users notice.

Sometimes, it feels like the device is trying, but there’s no flavour or sensation. That’s your hint it might be time for a refill or a replacement.

Noticeable Change in Flavour: Burnt or Harsh Taste

One of the most unpleasant signs of an empty vape is a burnt taste. If your device suddenly tastes sharp, dry, or just plain bad, it may not have any liquid left to protect the coil.

The coil inside your vape is designed to heat e-liquid—not air. When there’s nothing left to vaporize, the coil burns itself, causing that awful taste. If this happens with a device like the Hayati Pro Ultra Plus, it's likely that the pod or e-liquid is finished.

This burnt taste is not something to ignore. It's often the final sign that your vape needs replacing.

Check the Visible Oil Level

Some vape pods have a small window that shows how much liquid is inside. If your device has this feature, hold it up to the light and check inside.

No visible liquid? That’s a clear sign it’s empty. If the oil level is very low or sitting beneath the coil holes, it’s time to stop using the pod. Continuing to vape it dry could damage the coil and give you an even worse taste.

Even if your vape doesn't have a window, you might be able to see liquid by removing the pod or looking closely at the tank.

Air Bubbles That Don’t Move

When a vape is working well and still has e-liquid, small air bubbles rise through the tank as you use it. This happens as the liquid moves toward the coil.

But if those bubbles stay still—no matter how many puffs you take—it may mean the tank is empty. Trapped air and no liquid movement can signal that there’s nothing left to vaporize.

This sign is easy to miss, but it’s a helpful way to spot an empty vape, especially for closed systems.

Difficulty or Resistance When Drawing

When your vape is full and healthy, the draw is smooth and easy. You pull in, and the vapour flows. But when it's empty or nearly dry, that smooth pull can change.

If you're pulling harder than usual or the device feels clogged, it might mean there's no liquid left to keep things flowing. Sometimes, this also makes the vape sound different—more like a soft hiss or no sound at all.

With high-capacity models like the Hayati Pro Ultra 15000, this can happen after a long period of use.

Feeling Changes in Airflow or Draw Resistance

Pay attention to how the airflow feels. A full vape gives you a nice, even draw. An empty vape often feels like air is moving weirdly—or not at all.

You might notice the airflow feels flat, or there’s a slight resistance that wasn’t there before. These small changes are easy to ignore, but they can signal that your e-liquid has run out or the coil is drying up.

It’s not just the flavour that changes—how the vape feels in use is just as important.

Lightweight Device or Blinking Indicator Light

Most disposable vapes don’t weigh much to begin with, but when they’re nearly empty, they feel even lighter in your hand. That missing weight? It’s the e-liquid that’s all gone.

Some vapes also have small lights that blink when something’s wrong. If your device flashes when you try to puff, it could mean the battery is low—or the e-liquid has run out. Always check the light guide from the maker if your vape has one.

If you're not sure whether it's the battery or the juice, charge it and try again. If the blinking continues with no vapour, it’s probably empty.

What to Do When Your Vape Is Empty

If you've noticed one or more of these signs, don’t keep puffing. Using an empty vape can burn the coil, make the device overheat, or give off bad tastes. It’s time to take action.

You can either:

• Refill it (if your device is refillable)

• Replace the pod (for pod-based systems)

• Dispose of it safely and use a new one (for disposable models)

Continuing to use an empty device is never a good idea. Not only does it taste bad—it can also shorten the life of your vape.

How to Make Your Vape Last Longer

While every vape has a limit, there are ways to get the most from your device:

Keep it stored upright and in a cool place. Don’t leave it in a hot car or on a sunny windowsill. Heat can thin the liquid and make it run out faster.

Take short, slow puffs instead of long, heavy ones. This gives the coil time to soak in more e-liquid and prevents dry hits.

Charge the device before it goes completely flat. This helps keep the battery strong, especially in rechargeable models.

If you follow these tips, you’ll enjoy smoother puffs—and you won’t run out as quickly.

Conclusion

It’s easy to miss the early signs of an empty vape, but once you know what to look for—less vapour, bad taste, or blinking lights—it becomes simple to spot.

Whether you're using a Hayati Pro Ultra 15000 or the Hayati Pro Ultra Plus, these signs apply to almost every modern vape on the market. Watching out for them can save your device, your coil, and your vaping experience.
