IQOS Firmware Update - How to upgrade IQOS Firmware
If you already have an IQOS 3 device and would like to use your IQOS 3 DUO Holder with the IQOS 3 Pocket Charger, you might need to upgrade your firmware.
To understand whether your current IQOS 3 requires an upgrade, do the following:

2. Press the Pocket Charger button to check the Holder status light:
a. If the light blinks once – need upgrade
