    Battery Degradation

    IQOS devices, including holders, contain a lithium-ion battery. The lithium-ion battery in the devices is a consumable component that degrades with usage and age. This is a natural process common to all rechargeable lithium-ion batteries. As the battery ages, the active ingredients inside the battery become less capable of retaining energy, resulting in a permanent decrease in maximum battery capacity and usable energy. In addition, the active ingredients become less effective in delivering energy, resulting in a decrease of the battery’s ability to provide sufficient power for electronic device components to operate. As a result, where relevant, the duration of experience may appear to be shorter, the number of puffs or experiences with one full charge may appear to be fewer, the second consecutive use might be shorter or missing, or some device features, such as autostart or double tap for the IQOS ILUMA holder, may not perform.

    The battery is a chemical system that requires certain temperature ranges during charge and discharge to work optimally and minimize battery capacity degradation over its lifetime. Although your device has a specific operating range within which the device will function, operating at the extreme ends of this range will degrade your battery faster. Your device comes with customized software to control the charging parameters in order to maximize the life of your device. These algorithms can support the longevity of your battery life, but they can still never fully mitigate the normal aging mechanisms of lithium batteries. High and low temperature operation of your device will accelerate the natural degradation of your battery. Even if you do not use your device the batteries contain chemical systems which can still degrade over time. In order to slow the battery degradation process, we recommend charging your device within the recommended temperature zone, not keeping it discharged for long periods of time and using the charging cables and power adaptors that come together with the device as per the user guides.

    Cigarettes produce tar – IQOS doesn’t Tar is the residue from smoke after a cigarette is burned. IQOS does not produce tar because it heats tobacco instead of burning it. It generates an aerosol residue that is fundamentally different from tar and consists of significantly lower levels of harmful chemicals.* Switching completely to IQOS is less harmful than continuing to smoke.** * Average reductions in levels of a range of harmful chemicals (excluding nicotine) compared to cigarette smoke.

    Cigarettes produce high amounts of carbon monoxide - IQOS doesn’t Cigarettes burn tobacco, which produces high amounts of carbon monoxide. IQOS doesn’t burn tobacco, producing on average 98% less carbon monoxide (CO) and significantly lower levels of other harmful chemicals compared to cigarettes.* *We measured the levels of the 9 harmful chemicals the World Health Organization recommends to reduce in cigarette smoke, which do not include nicotine, and these are reduced on average by 95%.
