The iPhone 18 Pro Max focuses heavily on professional video features. It can record 4K video at up to 120fps and supports Dolby Vision HDR, ProRes, ProRes RAW, Apple Log 2 and spatial video/audio recording.
For users interested in professional video workflows, Apple’s ProRes, ProRes RAW and Log support provide a particularly broad set of recording options. Xiaomi, meanwhile, offers the higher 8K recording resolution.
Selfie Camera
The Xiaomi 18 Pro Max comes with a 50MP front camera featuring PDAF and support for 4K video at 30fps and 60fps.
The iPhone 18 Pro Max uses an 18MP multi-aspect ultrawide front camera with PDAF and an SL 3D sensor. It supports 4K recording at up to 60fps and includes features such as Dolby Vision HDR, spatial audio and Apple Log 2.

The iPhone 18 Pro Max has a market-dependent battery capacity of 5,391mAh for the Nano-SIM model and 5,567mAh for the eSIM-only model. Apple supports fast wired charging, with the supplied specification stating up to 50% in 15 minutes. It also supports up to 25W MagSafe/Qi2 wireless charging and 4.5W reverse wired charging.
Based purely on the listed battery capacities and charging specifications, Xiaomi places considerably more emphasis on battery size and charging speed.
Connectivity and Other Features
Both phones support 5G, Wi-Fi 7, Bluetooth 6.0, NFC, USB Type-C, UWB and satellite-related features, although the exact implementations differ.
The Xiaomi 18 Pro Max includes an infrared port, which can be useful for controlling compatible household electronics. It also supports NavIC and features an ultrasonic in-display fingerprint sensor.
The iPhone 18 Pro Max relies on Face ID for biometric authentication and includes a second-generation UWB chip. Apple also lists Emergency SOS, Messages and Find My via satellite.
Neither phone includes a 3.5mm headphone jack.
Xiaomi 18 Pro Max vs iPhone 18 Pro Max Price in India
The Xiaomi 18 Pro Max is expected to start at ₹89,999 in India, according to the supplied pricing information.
The iPhone 18 Pro Max starts at ₹1,79,900 for the 256GB model in India.
That creates a substantial price difference between the two phones. The Xiaomi model is positioned at roughly half the starting price of the iPhone 18 Pro Max while offering flagship-level specifications in areas such as the display, cameras, battery and charging.
Which Phone Offers What?
The two phones have clearly different hardware priorities.
The Xiaomi 18 Pro Max focuses on a large 8,500mAh battery, 100W charging, a 4,000-nit display, a rear secondary screen and high-resolution 200MP cameras. It also offers up to 16GB RAM and a Leica camera system.
The iPhone 18 Pro Max emphasizes Apple’s A20 Pro platform, iOS 27, a high-resolution Super Retina XDR display, professional video formats, Face ID, satellite connectivity and storage configurations reaching 2TB.
Rather than being identical alternatives, the specifications show two different flagship philosophies: Xiaomi emphasizes hardware specifications and charging capabilities, while Apple places greater emphasis on its software ecosystem, custom silicon and advanced video features.
Xiaomi 18 Pro Max vs iPhone 18 Pro Max: Verdict
The Xiaomi 18 Pro Max and iPhone 18 Pro Max are both high-end smartphones, but their specifications reveal significant differences.
The Xiaomi 18 Pro Max stands out with its 8,500mAh battery, 100W wired charging, 50W wireless charging, 200MP dual-camera setup, 4,000-nit display and secondary rear screen. Its expected ₹89,999 starting price also puts it in a very different price category.
The iPhone 18 Pro Max offers a 2nm A20 Pro chip, 2TB maximum storage, 4K 120fps video recording, ProRes RAW, Apple Log 2, Face ID and Apple’s iOS ecosystem. Its starting price of ₹1,79,900 is substantially higher.
For a buyer comparing specifications, the biggest areas to consider are therefore the operating system, camera processing and video features, battery and charging requirements, ecosystem preferences, and the large difference in starting price.
