Apple iPhone 18 Pro Max rumored at 240 g, iPhone Ultra launch delayed

Apple’s next flagship could tip the scales at 240 g, matching the iPhone 13/14 Pro Max, as a 5,500 mAh battery pushes the iPhone 18 Pro Max’s weight up from the 233 g of the iPhone 17 Pro Max【1】. The heft and a possible September delay for the first foldable iPhone Ultra raise questions about Apple’s material strategy and product rollout cadence.

Heavier flagship, same aluminum chassis

Rumors from Weibo‑leaker Ice Universe suggest the iPhone 18 Pro Max will retain an aluminum frame while housing a larger battery, resulting in a 9 mm‑thick chassis and a 240 g body【1】. This would make it the heaviest iPhone since the stainless‑steel iPhone 13 Pro Max, reversing the weight trend set by the titanium‑based iPhone 15 Pro Max (221 g) and aluminum‑based iPhone 17 Pro Max (233 g)【1】. The jump from the iPhone 17 Pro Max’s 5,088 mAh eSIM battery to the rumored 5,500 mAh unit represents roughly an 8 % capacity increase, potentially extending talk time but also affecting ergonomics.

Foldable iPhone Ultra faces timing uncertainty

Apple’s upcoming foldable, tentatively called iPhone Ultra, was slated for a September launch alongside the iPhone 18 Pro line【3】. However, the article notes that “production capabilities may play a part” and that new product categories often encounter delays, though the prior iPhone Air debuted on schedule【3】. No concrete specs were released, but analysts expect the Ultra to unfold to a size comparable to an iPad mini, positioning it as a bridge between smartphones and tablets【2】.

Competitive and market implications

If Apple proceeds with a heavier, aluminum‑based Pro Max, it may signal a shift away from premium metals to prioritize battery life and durability, a move that could influence rivals’ material choices. Meanwhile, a postponed Ultra launch could give competitors like Samsung and Huawei additional runway to refine their own foldables before Apple’s entry, potentially eroding the novelty advantage Apple hopes to claim.

What to watch

• Confirmation of the iPhone 18 Pro Max’s official weight and battery size at the September keynote (likely Sept 9)【3】.
• Any revised launch date for the iPhone Ultra, especially if Apple cites supply‑chain or production hurdles.
• Competitor announcements on foldable devices in Q4 2026, which could reshape the market dynamics ahead of Apple’s entry.

The iPhone 18 Pro Max’s increased mass underscores Apple’s trade‑off between battery capacity and handling comfort, while the uncertain timing of the iPhone Ultra highlights the challenges of bringing a new form factor to market. Both factors will shape Apple’s positioning in the premium smartphone segment and its ability to set the pace for next‑generation devices.
