The iPhone 11 Pro Max is a smartphone designed and marketed by Apple, announced on September 10, 2019, and released on September 20, 2019 — the large model of the first "Pro" iPhone generation, alongside the iPhone 11 Pro and iPhone 11. It succeeded the iPhone XS Max with the same 6.5-inch Super Retina XDR class display and stainless build, the generation's triple camera and A13 Bionic, and the year's single most dramatic spec: battery life five hours beyond its predecessor — the largest one-generation endurance jump in the line's history, and the phone that made "all-day battery" literal for heavy users.

Reviews crowned it the best phone of 2019 outright, with the asterisk that its 226-gram mass and $1,099 floor made it a deliberate choice. Like its smaller twin it served one year, discontinued at the iPhone 12 Pro Max's debut.

The Pro Max scales the generation's frosted matte-glass back and triangular triple-lens plateau to the 6.5-inch frame at 226 g — 18 heavier than the XS Max, nearly all of it battery. Midnight Green, Space Gray, Silver, and Gold; four-meter IP68; the polished steel band unchanged. It was the last Max with the rounded-sided design language, the 12 generation moving to flat edges the following year.

The five-hour battery gain came from everywhere at once: a 25% larger 3,969 mAh cell filling the space the thinner display driver and rearranged logic board freed, the XDR panel's 15% power saving, and the A13's efficiency cores drawing a third the power of the A12's. Endurance tests routinely cleared a day and a half; the 18 W USB-C charger in the box replaced the long-mocked 5-watt brick.

Identical to the iPhone 11 Pro — the 0.5×/1×/2× triple array, Night mode, Deep Fusion, four 12-megapixel cameras, extended-dynamic-range 4K — and on the Max's 6.5-inch XDR panel the results simply had a better viewfinder. The camera parity between Pro sizes, begun in the XS year, was now policy: the Max premium bought screen and battery, nothing hidden.

iOS 13 at launch, Deep Fusion via 13.2, and the current iOS release train ever since — the 2019 Pro generation still updating seven years on.

The Pro Max repeated the Max-tier pattern of outselling its smaller sibling, and reviews were the year's most emphatic: best display, best camera, and a battery result reviewers called the real headline of the generation. The weight and price were the only sustained complaints. It was discontinued on October 13, 2020, one year in.

The 11 Pro Max set the modern expectation that the biggest iPhone is also the longest-lasting — the battery crown the Max/Pro Max tier has defended in every generation since, through the current iPhone 17 Pro Max. With its siblings it closed the rounded-design era at its peak: the best-reviewed, best-selling send-off the 2014 design language could have asked for.
