iPhone 18 Pro Max leak shows new camera sensor and larger battery

Apple’s upcoming iPhone 18 Pro Max may debut a Sony IMX‑905 primary camera sensor, a 5,425 mAh eSIM‑only battery and the A20 Pro processor in a new wafer‑level multi‑chip package, according to recently surfaced prototype documents and leak‑derived specifications [1][3].

New hardware blocks

The most concrete change is the camera. Prototype data points to Apple swapping the IMX‑903 sensor used in the iPhone 17 Pro line for a newer Sony IMX‑905 sensor on both the iPhone 18 Pro and Pro Max [1]. A larger sensor typically delivers better low‑light performance and higher resolution, and the leak aligns with earlier reports of a variable‑aperture system that could give users optical control over depth of field.

Battery capacity also appears to be getting a sizable boost. A social‑media leak, reported by The Hans India, lists a 5,425 mAh battery for the eSIM‑only version of the iPhone 18 Pro Max, up from the 5,088 mAh unit in the iPhone 17 Pro Max [3]. The same source cites a 5,235 mAh cell for the Nano‑SIM variant, both figures exceeding the previous generation by roughly 6‑7 percent.

Under the hood, Apple is expected to introduce the A20 Pro chip built on TSMC’s 2 nm process. The prototype shows the chip using a wafer‑level multi‑chip module (WMCM) instead of the InFO‑PoP packaging used in earlier silicon, a shift that could allow tighter integration of CPU, GPU, Neural Engine and memory [1]. The new layout also moves the processor closer to the edge of the logic board, potentially improving heat dissipation and repairability.

Connectivity and design tweaks

Apple may keep its modem split by region. The US models are likely to retain Qualcomm hardware for 5G mmWave support, while other markets could receive Apple’s in‑house C2 modem, which currently lacks mmWave capability [1]. This mirrors Apple’s previous approach of balancing performance with supply‑chain considerations.

Design-wise, leaked images from a Tata Electronics data breach show a familiar flat‑edged silhouette, centred USB‑C port and triple‑camera module, but with a slightly taller camera bump and a matte silver finish that resembles the titanium look of the iPhone 16 Pro series [2]. A rumored “Dark Cherry” colour also appears in the visual leak, suggesting a modest palette refresh rather than a full redesign.

What to watch

• Official launch timing: Apple typically unveils new iPhones in September; the leak suggests a launch “just over two months away” from late June [2].
• Supply‑chain security: Tata Electronics’ cyber‑attack and the resulting document leak may prompt Apple to tighten partner security protocols [2].
• Competitor response: Samsung’s rumored 5,000 mAh battery in the Galaxy S26 Ultra could become a benchmark for Apple’s battery claim [3].

If the leaked specifications hold, the iPhone 18 Pro Max would combine a higher‑resolution sensor, a larger battery and a more efficient A20 Pro chip, potentially extending both performance and endurance over the iPhone 17 Pro line. The extent to which these hardware upgrades translate into real‑world advantages—and whether Apple will introduce a variable‑aperture lens—remains to be confirmed at the official unveiling.
