Xiaomi 18 Pro Max vs iPhone 18 Pro Max: What's the Catch?
SpexHive Editorial

review
On paper, this should not even be a fair fight. One phone costs about €920. The other costs €1,599. Yet the cheaper one packs a battery more than 3,000 mAh bigger, charges at 100 W, carries a 200 MP main camera, and hides a second screen on its back.
So why would anyone still spend the extra €680 on Apple’s flagship? We went through every line of both spec sheets in the SpexHive database to find out and the answer is not what the headline numbers suggest. Stay until the end: the most important difference between these two phones is not on the box.
If you want the most phone for the money; the biggest battery, the fastest charging and the loudest spec sheet, the Xiaomi 18 Pro Max is the one to beat. If you want the most polished all round package, the best video tools and the Apple ecosystem, the iPhone 18 Pro Max still has a case, and we explain exactly who that case is for below.
Key specifications from the SpexHive database. Prices and storage vary by region.
Round 1: Display, a closer fight than you think
Both phones use a 6.9 inch, 120 Hz LTPO panel, so scrolling will feel buttery on either. The differences are in the details. The Xiaomi claims a 4,000 nit peak, an extreme 2,160 Hz PWM dimming rate (gentler on sensitive eyes at low brightness), and a built in Smart Privacy Display feature that uses physical pixel baffles to block shoulder surfers from the sides when activated.
The iPhone’s peak is lower at 3,000 nits, but it packs more pixels (1320 x 2868, about 460 ppi against 418 ppi) and adds an anti reflective coating on its Ceramic Shield 2 glass (though iPhone users wanting a privacy screen still have to buy a physical third party screen protector). In our own measurement, the iPhone reached 968 nits of maximum brightness in a typical test.
Winner: Xiaomi takes this round for pure technology, winning on peak brightness, eye strain protection, and built in privacy display hardware, while Apple holds its ground on pixel sharpness and anti reflective glare control.
Round 2: Performance, two 2 nm monsters
Both phones are built on a 2 nm chip. The Xiaomi runs the Snapdragon 8 Elite Extreme Gen 6 with eight cores and a prime core clocked at 5.01 GHz. The iPhone uses Apple’s A20 Pro with six cores, topping out at 4.93 GHz. Fewer cores, yet Apple’s numbers have historically punched above what the clock speeds suggest.
The iPhone 18 Pro Max scored 3,463,072 in AnTuTu, 12,794 in Geekbench 6 and 7,931 in 3DMark Wild Life Extreme in our tests. We do not have lab results for the Xiaomi yet, so we will not guess, we will update this article when they arrive. What we can say: with up to 16 GB of RAM and fast UFS 4.1 storage, the Xiaomi will not feel slow for a second.
Winner: too close to call until independent results land.
Round 3: Cameras, 200 MP versus a smarter 48 MP
This is where the spec sheets look the most different, and where the numbers can mislead you. The Xiaomi brings a 200 MP main sensor (23 mm, f/1.7, optical stabilisation) and a 200 MP periscope telephoto with 3.2x optical zoom, plus a 50 MP ultra wide, Leica lenses and laser autofocus. On the front, a 50 MP selfie camera.
The iPhone answers with three 48 MP cameras: a main camera with a variable aperture from f/1.5 to f/4.0, a 100 mm periscope at 4x optical zoom, and a very wide 120° ultra wide. The selfie camera is 18 MP.
More megapixels do not automatically mean better photos — sensor size, processing and lenses matter more, and the two main sensors are the same size (1/1.28"). Where the iPhone pulls clearly ahead is video: ProRes RAW up to 120 fps, Apple Log 2, Dolby Vision 4K at 120 fps and spatial video. The Xiaomi counters with 8K at 30 fps, 10 bit Dolby Vision, LOG recording and ultra slow motion up to 960 fps at 1080p.
Winner: Xiaomi for resolution and zoom flexibility on paper, iPhone for serious video work.
Plot twist #1: the battery gap is not small
Here is the number that made us double check the database: the Xiaomi has an 8,500 mAh silicon carbon battery. The iPhone has 5,391 mAh (5,567 mAh in the eSIM only model). That is roughly 55–58% more capacity in a phone that is lighter (235–240 g against 249 g) and thinner (8.4 mm against 8.8 mm).
Then there is charging. The Xiaomi supports 100 W wired, 50 W wireless and even 27 W reverse wireless to top up your earbuds or another phone. The iPhone gets 50% in 15 minutes over a wire, 25 W wireless through MagSafe/Qi2 and 4.5 W reverse wired charging.
To be fair to Apple: capacity is not endurance. Software efficiency matters, and the iPhone posted an active use score of 19 hours 20 minutes in our testing, with an EU label rating of 62 hours of endurance. A bigger battery is a big head start — but we will only know the real winner once the Xiaomi is tested the same way.
Winner: Xiaomi, by a distance, on everything the spec sheet can measure.
Software and ecosystem: the part a spec sheet cannot show
The Xiaomi 18 Pro Max runs Android 17 with HyperOS 4; the iPhone 18 Pro Max runs iOS 27. If your family, watch, earbuds and laptop already live in Apple’s world, the iPhone’s ecosystem is a real reason to stay. If you like customising your phone, sideloading or using a single phone with two SIM cards, Android’s flexibility is a plus — the Xiaomi lists dual Nano SIM, while the iPhone leans on eSIM in many markets (in the USA it is eSIM only).
Plot twist #2: the screen on the back
We saved this for later because it is the detail most people miss. Under “Display”, the Xiaomi’s spec sheet lists a secondary display: a 2.9 inch LTPO AMOLED panel (596 x 976) with the same 120 Hz refresh rate and 4,000 nit peak brightness as the main screen. In practice that means a second screen for glanceable notifications, a viewfinder for rear camera selfies and more, something no iPhone offers.
Add three speakers with Dolby Atmos, 24 bit/192 kHz Hi Res audio, an infrared blaster that can control your TV and air conditioner, and an ultrasonic under display fingerprint sensor, and the Xiaomi starts to look like the phone that simply does more.
Price: where the argument really ends
The iPhone 18 Pro Max launches at £1,299 / €1,599. The Xiaomi 18 Pro Max sits at about €920. That is roughly €680 less — about 42% cheaper, for a phone with the bigger battery, the faster charger and the higher resolution cameras. Prices differ by country and by storage tier, so check local listings, but the gap is hard to ignore.
So what does the extra money buy? Mostly things that are hard to put in a table: iOS polish, long term software support, resale value, accessories like MagSafe and the best video recording tools on any phone.
Who should buy which?
Buy the Xiaomi 18 Pro Max if…
battery life and fast charging come first — 8,500 mAh and 100 W are hard to beat;
you want maximum hardware for your money and extras like the rear screen and IR blaster;
you prefer Android and its customisation.
Buy the iPhone 18 Pro Max if…
you are already invested in Apple devices and services;
you shoot a lot of serious video — ProRes RAW and Apple Log 2 are in a class of their own;
you value long term resale value and a polished, predictable experience.

The verdict and the thing no spec sheet can tell you
Judged only by the numbers, the Xiaomi 18 Pro Max wins more rounds: battery, charging, price, camera resolution and extras. The iPhone 18 Pro Max wins where polish, video quality and ecosystem matter more than raw specifications. The honest answer is that the better phone is the one that fits the life you already have.
One last tip: before you buy, check the things we cannot measure from a database — software update promises in your country, local warranty and repair options, and how the phone feels in your hand. Then run the full comparison one more time with your own priorities in mind.
