The IQOS ILUMA i looks familiar because its core heating system is largely unchanged. The real upgrade is how the device works around each session: a Touch Screen, Pause Mode, FlexPuff, configurable battery modes and the option of a third consecutive use.
Quick answer: IQOS ILUMA i is the better device, but it does not deliver a fundamentally different heating experience from the original IQOS ILUMA. Both use the bladeless SMARTCORE INDUCTION SYSTEM and compatible SMARTCORE sticks. Upgrade mainly for the new controls and flexibility—not because you expect a dramatic change in taste.
IQOS ILUMA i
The stronger choice for new buyers who want Pause Mode, clearer session information and more flexible back-to-back use.
IQOS ILUMA
Still a sensible option when heavily discounted because the core induction technology and stick compatibility remain comparable.
Useful, not essential
Existing ILUMA owners should upgrade only if they will regularly use Pause Mode, FlexPuff or a third consecutive session.
IQOS ILUMA i vs ILUMA: Key Differences
The table below shows where IQOS ILUMA i meaningfully improves on the original model—and where the two devices remain essentially the same.
| Feature | IQOS ILUMA i | IQOS ILUMA |
|---|---|---|
| Heating technology | SMARTCORE induction heating | SMARTCORE induction heating |
| Touch Screen | Yes — shows heating progress, remaining time and available uses | No — standard status lights |
| Pause Mode | Yes — pause for up to 8 minutes when available | No |
| FlexPuff | Yes — may provide up to four additional puffs depending on usage | No |
| Consecutive holder uses | Up to 3 in Performance Mode when Pause is not used | Up to 2 |
| Battery modes | Performance Mode and Eco Mode | No selectable FlexBattery modes |
| Uses per full Pocket Charger charge | Up to 20 | Up to 20 |
| Full Pocket Charger charging time | Approximately 135 minutes | Approximately 135 minutes |
| Compatible sticks | SMARTCORE sticks made for the ILUMA platform | SMARTCORE sticks made for the ILUMA platform |
| Routine holder cleaning | Not required | Not required |
The most important distinction: IQOS ILUMA i improves control and convenience, while the underlying induction-heating platform remains the same. That is why the upgrade feels practical rather than revolutionary.
What Actually Changed in IQOS ILUMA i?
IQOS did not replace the induction-heating platform used in the original ILUMA. Instead, the company redesigned how users control the Holder and manage each session. The four meaningful additions are the Touch Screen, Pause Mode, FlexPuff and FlexBattery.
Touch Screen
The most visible difference is the small Touch Screen built into the IQOS ILUMA i Holder. It displays the preheating status, remaining session time and number of available uses more clearly than the conventional indicator lights on the original ILUMA.
It is not a full touchscreen like the display on a phone. Instead, it is a compact gesture-controlled interface designed for quick status checks and features such as Pause Mode.
Pause Mode
Pause Mode allows an active session to be interrupted for up to eight minutes and resumed with the same stick. To activate it, the user swipes down across the Touch Screen and later swipes up to continue.
The feature is useful when a session is interrupted by a phone call, transport announcement or any situation where continuing immediately is inconvenient. However, Pause Mode has several limitations:
- It is available only in Performance Mode.
- It must be activated during the first three minutes or first eight puffs.
- It can be used during only one of the first two consecutive sessions.
- The Holder turns off if the session is not resumed within eight minutes.
- Using Pause prevents FlexPuff and the third consecutive use from becoming available.
Pause Mode is therefore genuinely practical, but it is not an unlimited stop-and-resume function.
FlexPuff
FlexPuff monitors how an adult user consumes a stick and may provide up to four additional puffs when the device determines that more of the session is available. Activation is automatic, but the additional puffs are not guaranteed during every use.
The feature does not mean that IQOS ILUMA i heats tobacco more strongly than the original ILUMA. It simply gives the device more flexibility in how it ends a session. FlexPuff is unavailable whenever Pause Mode has been used.
FlexBattery
FlexBattery provides two operating profiles for the IQOS ILUMA i Holder:
- Performance Mode: allows up to three consecutive uses without Pause, or two consecutive uses with Pause available during one of them.
- Eco Mode: limits the Holder to one use per charge cycle to reduce battery strain and support a longer operational lifespan.
Performance Mode is the sensible default for most users. Eco Mode is more relevant to people who rarely need consecutive sessions and plan to keep the same device for several years.
Important trade-off: Pause Mode, FlexPuff and three consecutive uses cannot all be used during the same Holder charge. The device allocates its available battery and session capacity differently depending on how it is used.
Does IQOS ILUMA i Perform Better Than IQOS ILUMA?
In terms of core heating performance, the difference is small. Both devices use the same bladeless SMARTCORE INDUCTION SYSTEM, which heats a metal element inside the compatible stick rather than using a heating blade inside the Holder.
This means IQOS ILUMA i should not be treated as a major upgrade in heating quality. Its advantage comes from better session management—not from a completely new way of heating tobacco.
Effectively the same
Both generations use induction heating with specially designed SMARTCORE sticks.
ILUMA i wins
The Touch Screen, Pause Mode and FlexPuff make sessions easier to monitor and manage.
No dramatic upgrade
Stick condition, flavor choice and usage pattern are likely to matter more than switching between these two devices.
Is There a Difference in Taste?
Adult users should not expect the same stick to taste fundamentally different simply because it is used with IQOS ILUMA i instead of the original ILUMA. The heating platform and compatible stick format remain the same.
FlexPuff may extend some sessions by providing additional puffs, but it does not introduce a new heating system or a stronger operating mode. Flavor intensity still depends mainly on the selected stick. Readers comparing available options can consult our ranking of the best TEREA flavors in 2026.
Our assessment: buy IQOS ILUMA i for its added convenience and flexibility. Do not buy it solely because you expect stronger flavor or a substantially different tobacco experience.
Stick Compatibility: Do Both Devices Use the Same Products?
Yes. IQOS ILUMA i and IQOS ILUMA use SMARTCORE sticks specifically designed for the ILUMA platform. This includes TEREA and, in markets where they are officially sold, other compatible ranges such as DELIA or LEVIA.
Availability differs by country, so a stick being part of the wider ILUMA ecosystem does not mean it is officially sold in every market. Our IQOS stick compatibility guide provides a device-by-device breakdown of the major stick families.
Do not use HEETS in either device. HEETS are made for older IQOS models with blade-based heating and are not designed for the SMARTCORE induction system. Likewise, TEREA sticks should not be inserted into older blade devices because their internal metal component may damage the blade.
If you are moving from an older IQOS generation, read our detailed TEREA vs HEETS comparison before buying sticks. Moving from IQOS ILUMA to ILUMA i, however, does not require changing your compatible stick range.
Cleaning and Everyday Maintenance
Neither model has a heating blade, and the tobacco portion of a compatible SMARTCORE stick remains sealed during use. As a result, both devices avoid the routine internal blade cleaning associated with older IQOS generations.
Users should still keep the Holder opening, Pocket Charger and charging contacts dry and free from visible dirt. However, there is no meaningful maintenance advantage when comparing IQOS ILUMA i directly with IQOS ILUMA—they are already based on the same cleaner, bladeless design.
Battery Life and Charging
Both devices provide up to 20 uses from a fully charged Pocket Charger and take approximately 135 minutes to charge fully under normal conditions. The practical difference is how many sessions the Holder can deliver before it must return to the charger.
| Battery Feature | IQOS ILUMA i | IQOS ILUMA |
|---|---|---|
| Uses per full Pocket Charger charge | Up to 20 | Up to 20 |
| Standard consecutive uses | Up to 3 without Pause | Up to 2 |
| Uses when Pause is available | Up to 2, with Pause available during one session | Pause not supported |
| Selectable battery modes | Performance and Eco | No |
| Approximate full charging time | 135 minutes | 135 minutes |
The third consecutive use is valuable for users who regularly consume several sticks close together. However, it does not significantly increase total daily capacity because the Pocket Charger still supports approximately 20 uses before it needs to be recharged.
Battery winner: IQOS ILUMA i. Total Pocket Charger capacity is similar, but the newer Holder gives users more freedom between charging cycles.
Design, Size and Accessories
IQOS ILUMA i keeps the familiar two-part format: a lightweight Holder paired with a larger Pocket Charger. The general shape and dimensions are very close to the original ILUMA, so the newer device does not feel like a major physical redesign.
The Touch Screen is the clearest visual difference. It replaces the simpler Holder indicators with a more informative interface while preserving the compact cylindrical shape.
- Existing ILUMA charging cables and compatible power adaptors can be used with ILUMA i.
- Many interchangeable Pocket Charger doors, Holder rings and other accessories fit both generations.
- An ILUMA i Holder can be charged in an original ILUMA Pocket Charger and vice versa.
- Available colors and accessory collections vary by country.
Existing ILUMA owners therefore do not necessarily need to replace every accessory when upgrading. Still, compatibility should be checked for unusually shaped third-party cases rather than assumed from the product name alone.
Price and Overall Value
IQOS pricing varies considerably by country, introductory promotion and trade-in offer. The original ILUMA may also appear at clearance prices as retailers shift attention toward the newer ILUMA i range.
Pay More for ILUMA i If You Want:
- Pause Mode for interrupted sessions
- A visible session countdown
- Up to three consecutive uses
- FlexPuff and adjustable battery behavior
- The more future-facing model
Choose Original ILUMA If:
- It is available at a substantial discount
- You normally use one or two sticks at a time
- You do not need to pause sessions
- Basic indicator lights are sufficient
- Your existing device still works reliably
Our value rule: if IQOS ILUMA i costs no more than roughly 20% extra, choose the newer model. If the original ILUMA is around 30–40% cheaper, it remains the stronger budget purchase because the core heating system and compatible stick selection are effectively unchanged.
Be more cautious with heavily discounted used devices. Battery condition, remaining warranty and the condition of the charging contacts can matter more than the initial saving.
Should You Upgrade From IQOS ILUMA to ILUMA i?
For most existing IQOS ILUMA owners, upgrading is optional rather than necessary. The newer device offers better controls, but the fundamental heating technology, compatible sticks and overall maintenance requirements remain similar.
You Need Pause Mode
This is the strongest reason to upgrade. The original ILUMA cannot stop and resume an active session.
You Often Need Three Uses
ILUMA i is more convenient when two consecutive Holder sessions are regularly insufficient.
Your ILUMA Works Well
If you are satisfied with two uses and basic status lights, the upgrade offers limited practical value.
Which Model Should a New Buyer Choose?
A new buyer should generally choose IQOS ILUMA i. It offers more useful features, provides better information during each session and is likely to remain the more relevant model as the product range develops.
The original IQOS ILUMA makes more sense only when it is sold at a substantial discount. Paying close to the same price for the older model means giving up Pause Mode, FlexPuff, FlexBattery and the Touch Screen without receiving a meaningful advantage in return.
| User Type | Better Choice | Why |
|---|---|---|
| First-time ILUMA buyer | IQOS ILUMA i | More complete feature set and better long-term value |
| Current ILUMA owner | Keep IQOS ILUMA | Upgrade only if the new controls solve a real problem |
| Frequent back-to-back user | IQOS ILUMA i | Supports up to three consecutive uses without Pause |
| Occasional user | Either model | Core heating and stick compatibility are similar |
| Budget-focused buyer | IQOS ILUMA | Worth considering when significantly cheaper |
| User upgrading from a blade device | IQOS ILUMA i | Better to move directly to the newer ILUMA generation |
Final Verdict: IQOS ILUMA i Wins, but Not Everyone Needs It
IQOS ILUMA i is the clear overall winner. Pause Mode, the Touch Screen, FlexPuff and more flexible Holder battery management make it easier and more adaptable to use than the original IQOS ILUMA.
However, this is an interface and convenience upgrade—not a revolution in heating performance. Both devices use the same core induction system, support the same ILUMA-compatible stick ecosystem and provide similar total Pocket Charger capacity.
IQOS ILUMA i
Best for new buyers and anyone who will genuinely use Pause Mode or three consecutive sessions.
IQOS ILUMA
Best for satisfied existing owners who do not need the additional controls.
Discounted ILUMA
A smart purchase only when the saving is large enough to justify choosing the older model.
Frequently Asked Questions
What is the main difference between IQOS ILUMA i and IQOS ILUMA?
IQOS ILUMA i adds a Touch Screen, Pause Mode, FlexPuff, FlexBattery and up to three consecutive uses. The original IQOS ILUMA has simpler indicator lights, no Pause function and supports up to two consecutive uses.
Does IQOS ILUMA i taste better than IQOS ILUMA?
Not necessarily. Both devices use the same SMARTCORE induction-heating platform and compatible stick format. Flavor differences are more likely to come from the selected stick and individual usage pattern than from the device generation.
