Apple’s most expensive iPhone Duo accessory, the Folio with Standfuß, is priced at €149, more than double the €59 price of the cheapest iPhone 18 Pro Max silicone case. The figure comes from the German tech outlet heise, which listed the Folio’s price in its coverage of the Duo launch (heise – iPhone Duo: Offizielles Zubehör von Apple).
The standard iPhone Duo Case costs €89, which is roughly 51 % higher than the €59 silicone case. The percentage is calculated as (89‑59) ÷ 59 ≈ 0.509, or 50.9 % (rounded to 51 %). Both price points are tied to the 2026 launch period, as indicated in the source.

How the Duo accessories compare
Dividing the Folio price by the cheapest case gives a multiple of 149 ÷ 59 ≈ 2.53, meaning the Folio costs about 2.5 times more than the baseline iPhone 18 Pro Max silicone case. The Duo Case’s multiple is 89 ÷ 59 ≈ 1.51, or a 51 % premium over the same baseline. Both multiples are calculated directly from the figures supplied by heise; no conversion or external data were used.
Apple’s scale and financial backdrop
Apple Inc. is headquartered in Cupertino, California, and reported a fiscal year ending September 2026 with revenue of $265.6 bn, net income of $101.5 bn, total assets of $383.3 bn, and shareholders’ equity of $107.5 bn (SEC filing, Form 10‑Q, filed 31 July 2026). The company had 14.6 bn shares outstanding at the same date. These figures provide a sense of the scale from which the accessory pricing is derived.
At a launch price of at least €2 300 for the iPhone Duo itself (heise notes the device “mindestens 2300 Euro” expensive), the Folio adds roughly 6.5 % to the total cost, while the Duo Case adds about 3.9 %. For consumers, the premium accessories represent a non‑trivial incremental expense, especially given that only the Folio offers protection for the outer display. For Apple, the high‑margin accessories could bolster accessory‑related revenue, a strategy it has pursued with previous iPhone generations.
What remains unknown
The research packet does not confirm Apple’s current chief executive, noting the field as null. It also does not disclose whether additional Duo accessories will be released after launch, nor does it provide cost‑structure details that would clarify the profitability of the accessories. Those gaps are acknowledged explicitly.
