There are two ways to check how many uses you have left: 
On the IQOS Holder
Press and release the button on your IQOS  Holder:

• Two lights mean it’s ready for two uses
• One light means it’s ready for one use
• No light means the Holder isn’t charged.

On the IQOS Pocket Charger
Press and release the Pocket Charger button:

• Two lights mean it’s ready for two uses
• One light means it’s ready for one use

* If you use the IQOS 3 DUO Holder in the IQOS 3 Pocket Charger, you might need to upgrade your IQOS 3 Pocket Charger firmware so it can tell you when the Holder is ready to be used once.

The IQOS 3 DUO provides you with two consecutive uses before needing to recharge.
Once you’ve finished your first use, there’ll be one light  to show you have one more use left. If you’d like the second use right away, your IQOS Holder is instantly ready for you.

If you don’t need the second use right away, simply put your IQOS Holder back in the Pocket Charger for a quick recharge to give you two uses again.

You can register your device using NFC:

• Tap your smartphone on the device’s door to open the IQOS registration page on your phone
• Fill in your details and click to register. That’s it!

If your phone has an NFC chip, switch on the NFC functionality in your phone’s settings menu.
The two devices will connect automatically when you bring them close to each other (less than 4cm apart) and IQOS.com will open.

NFC stands for near-field communication (NFC). It allows two electronic devices - like your IQOS device and your phone - to communicate when you bring them within 4cm of each other.
Your IQOS device has NFC built in to make it even easier to access your account with quick and easy device registration, and straightforward instructions to help you learn how to use your IQOS device. With just one tap you can find your nearest store selling IQOS or contact our Customer Support.

Your IQOS 3 DUO device is designed to work in a wide range of temperatures, but tobacco sticks taste best when you use the device between 0 °C and 50 °C.

• One vibration means it’s starting to heat up (after you’ve pressed the Holder button to start).
• Two vibrations mean it’s ready to use.
• Two more vibrations mean your use is nearly over (it’ll vibrate 30 seconds before the end).

Press and hold your IQOS Pocket Charger button for 10 seconds (until the lights fade out) then release it. 
All the status lights will turn off, blink three times, and then progressively fade in to confirm the reset.

You can use the IQOS AC Power Adaptor from your previous IQOS devices. But the IQOS 3 DUO USB cable has a USB-C port, which is different from the IQOS 2.4 PLUS so please make sure you always use the right cable.

No, the IQOS 3 DUO Pocket Charger is not compatible with previous IQOS versions.
If you insert the IQOS 2.4 PLUS Holder into the IQOS 3 Pocket Charger, the Holder won’t fit because they’re different sizes.
If you accidentally insert the IQOS 3 Holder into the IQOS 2.4 PLUS Pocket Charger, the Pocket Charger lights will start blinking, but the Holder won’t charge.
Make sure you always charge your IQOS 3 Holder with the IQOS 3 Pocket Charger.

Your IQOS 3 DUO device doesn’t need to be fully charged to work but for the best experience, we recommend you fully charge the device before you use it for the first time. 
If your IQOS 3 DUO device is fully charged, you can use it up to 20 times before you need to recharge.

It takes approximately 120 minutes (two hours) to fully charge your IQOS 3 DUO Pocket Charger from an electrical outlet, using the IQOS AC Power Adaptor and USB cable.

Simply press your IQOS Pocket Charger button for one second. The LED lights will show the charge level – one light means your device has low battery and you need to charge it, four lights mean the device is more than 75% charged and ready to use.

IQOS 3 DUO has our fastest and most powerful Holder yet. IQOS 3 DUO offers two consecutive uses without needing to recharge. And one of the benefits is a faster charge time.
