IQOS ILUMA i Red Light Charging Issue: What Does It Mean?

Other signals:
- Flashing white lights on the holder: the device may be outside its operating temperature range.
- Yellow light on the holder: no experiences available.
- Yellow strip light on the pocket charger: low battery.
- A flashing “0” on the touch screen (three times): the holder is discharged. Make sure the pocket charger has enough battery, then place the holder in it correctly.

Model-Specific IQOS ILUMA i Charging Troubleshooting
The ILUMA i range has an all-in-one model and two holder-and-pocket-charger models. Identify yours first.
IQOS ILUMA i ONE Not Charging
The ILUMA i ONE is an all-in-one model. There is no separate pocket charger. It charges through its own USB-C port, so the cable, adapter, port and temperature matter most.
For the ILUMA i ONE, if the lights come on but the device will not charge, the charging ports may need cleaning. Unplug it and make sure the ports on the device and cable are clean and dry. Charge with a compatible adapter for about 90 minutes. Four solid white lights indicate a full charge.
IQOS ILUMA i PRIME Not Charging
The ILUMA i PRIME uses a holder and a pocket charger. For the ILUMA i PRIME, if the holder’s lights do not turn on, check that the pocket charger has enough battery.
Clean the holder’s contacts. Place it in the right direction. Let it charge until at least one circular light on the charger is steady white. Then remove the holder and swipe up across the whole touch screen.
