After fifteen days with the iPhone 18 Pro Max, I am ready to spill a few words and, in the process, surprise myself. The dust around the newest iPhone may take a while to settle, but its family resemblance to last year's flagship, the 17 Pro Max, runs deeper than a shared silhouette. So do you buy into the hype and take the plunge, or summon a Stoic's resolve and hold out for next year's 20th anniversary iPhone?
On paper and on LED billboards, the headline act is the clever variable aperture, a genuine feat of miniaturised engineering. The A20 Pro, which packs Apple's first 2nm smartphone chip, is an even grander flex of what unlimited R&D will yield. With its six-core CPU, seven-core GPU and dual 16-core Neural Engine, it is a tad faster at everything from erasing the support truck from your Concours d'Elegance photographs to cutting 4K drone footage from Raaya Maldives, and even pointing the camera at a bottle of Pinot Noir and enquiring about its provenance.
But after living with it as a daily driver, the more interesting question is whether the improvements are perceptible if you already own an iPhone 17 Pro Max. The biggest everyday difference between last year's toast of the town and this year's Apple is not the marginally improved camera or the incrementally faster processing, but the most unseen feature of them all: the battery. If you are a power user like me, that matters far more than opening Instagram half a second sooner.
Apple has pored obsessively over eking out the maximum from the 5391mAh cell in the physical-SIM version, which India gets. Markets with only the eSIM version get an even more ambitious 5567mAh battery, which translates to roughly two additional hours of rated video playback. Even that number is a rare confession. Apple lists no battery capacity on its spec pages anywhere in the world, and the figure surfaced only because EU rules oblige every smartphone sold in the bloc to carry an energy label. Apple ships iOS 27 with a Prepare to Ship setting for anyone who needs to send the phone onward to meet these regulations too, indicating a meaningfully large battery, yet again.
Having used every generation of iPhone before this, I can safely say that battery anxiety followed by that sisyphean ritual of hunting for a socket, is a thing of the past with the iPhone 18 Pro Max. I average a day and a half of use that includes photography, shooting and editing video, doom scrolling and work-related scrolling for almost every waking hour, and constant messaging and emailing.
Marketing claims notwithstanding, compared to the iPhone 17 Pro Max's 4,823mAh battery, the real-world gain in my hands felt far steeper than the supposed 11.8 per cent on the EU energy label. Apple's own ratings hint at why. It rates the Pro Max at 45 hours of video playback against 39 for its predecessor, which outpaces the capacity increase. Whether you are on a day trip without a charger, sharing your iPhone's wi-fi hotspot with a Mac or iPad, navigating all day, or anything in between, the iPhone's cortège of custom-built silicon works in perfect concert.
The A20 Pro pairs two new "super cores" with four efficiency cores, so the heavyweights are summoned only on demand. The memory now sits beside the processor in a wafer-level multi-chip module rather than stacked on top of it, and the vapour chamber has three times the surface area of the iPhone 17 Pro's. A cooler chip leaks less current, and leaked current is wasted battery. The new homegrown C2 modem uses 15 per cent less power than its predecessor, while Adaptive Power, which Apple says needs at least seven days to learn your charging habits, shaves what remains.
Apple has doubled down on the area where it was historically weakest, and it frees you from the tyranny of the battery indicator, that small Sword of Damocles hanging over every long day. It may sound less glamorous than the variable aperture lens or the vapour chamber, but when it comes to upgrading, it is the single biggest differentiator from last year's big boy iPhone.
