IQOS ILUMA i vs the Original ILUMA: What Actually Changed?
4 min read · Updated November 13, 2026
If you own an original ILUMA, the i will look familiar - deliberately so. The heating system and the sticks did not change. What changed is the layer of information and control wrapped around them. Here is what is genuinely new, and what stayed exactly the same.
What stayed the same
The core did not move: both generations heat TEREA sticks with the SMARTCORE induction system sealed inside the stick, so there is no blade to clean or break, and HEETS still do not work in either device. A session is still up to 6 minutes or 14 puffs, a full pocket charger still covers about 20 sessions, and a full charge still takes roughly 2 hours 15 minutes. If you switch, your sticks and your habits carry over untouched.
New: the touch screen
The original ILUMA communicates through LED lights and vibration - enough to know it is heating or running low, not much more. The ILUMA i holder has a touch screen that shows pre-heating status, the time left in your session and how many uses you still have available. It is the single change you will notice most often, because it answers the two questions the old device made you guess: how long is left, and how many sticks do I have?
New: Pause Mode
On the original ILUMA, a session is a one-way trip: once it ends early, that stick is done. The i adds Pause Mode - pause the session for up to 8 minutes and resume the same stick. It works in Performance Mode and has to be triggered early in the session (within the first 3 minutes or 8 puffs), but it removes the old all-or-nothing feel when something interrupts you mid-stick.
New: FlexPuff and FlexBattery
FlexPuff watches your drawing pace and adapts the session to it, which can add up to 4 extra puffs inside the same 6 minutes (it does not kick in if you used Pause Mode on that stick). FlexBattery gives you two charging personalities: Eco Mode, which is gentler on the holder battery - the maker says it can extend the battery's working life by up to a year - and Performance Mode, which unlocks a third back-to-back use from the holder where the original manages two, and enables Pause Mode.
Is it worth upgrading?
If your original ILUMA still works, nothing forces the move: the sticks are the same and the tobacco experience is designed to match. The case for upgrading is the quality-of-life layer - knowing your remaining uses at a glance, pausing instead of wasting a stick, and squeezing a third consecutive use out of the holder. Our IQOS section carries the current i generation, in both the two-piece ILUMA i and the all-in-one ILUMA i ONE.
