Xiaomi 17 arrived in China on September 25, 2025, signaling a bold shift in flagship design and power. The Xiaomi 17 Pro and Pro Max add a rear “Dynamic Back Display,” while the series standardizes on Qualcomm’s Snapdragon 8 Elite Gen 5. Batteries scale from 6,300mAh (Pro) to 7,500mAh (Pro Max), with the base Xiaomi 17 carrying a hefty 7,000mAh cell. All three support 100W wired and 50W wireless charging. Prices start at ¥4,499, with Chinese retail beginning September 27 after a rapid preorder window [1].

Xiaomi 17 secondary screens and AI use cases

Xiaomi is pushing the multi-screen smartphone idea into mainstream territory. The Xiaomi 17 Pro and Pro Max integrate a 2.7–2.9-inch Dynamic Back Display into the camera island, designed for quick glances without waking the main screen. Functionally, it doubles as a rear-camera viewfinder for higher-quality selfies and vlogging, while also serving music controls, timers, and a rotating set of AI-powered widgets for at-a-glance utility [2].

The placement matters. By positioning the auxiliary screen alongside the primary sensors, Xiaomi is encouraging creators to rely on the superior rear camera stack for framing and capture. That reduces friction for short-form video and photo workflows, which increasingly hinge on speed and flexibility rather than just image quality.

Wired’s early hands-on also highlights hardware headroom for the concept: the series targets peak brightness up to 3,500 nits for outdoor legibility, and configurations scale up to 16GB of RAM. For the Pro phones, those resources support the new back-display experiences while keeping the front experience responsive during heavy multitasking.

Xiaomi 17 batteries and charging by the numbers

Battery capacity is the story here. The Pro Max’s 7,500mAh pack is 19% larger than the 17 Pro’s 6,300mAh cell and roughly 7% larger than the standard Xiaomi 17’s 7,000mAh unit. The base model’s capacity is itself 11% higher than the Pro’s—an unusual distribution that prioritizes endurance for the entry model and the Max, while the Pro trades some milliamp-hours for a thinner profile and the new rear display.

Charging speeds are uniform across the series: 100W wired and 50W wireless. In practice, that consistency simplifies purchasing decisions across tiers, because fill times won’t vary wildly even as capacities differ. Expect the Pro Max to take longer to top off due to its sheer size, but once charged, it should deliver materially longer screen-on and standby times than the Pro.

Android Central reports that the standard Xiaomi 17 pairs its 7,000mAh battery with a 6.3-inch M10 panel, while the Pro and Pro Max add the Dynamic Back Display and keep the 100W/50W charging formula. The result is a lineup tuned for endurance without abandoning fast top-ups—a combination that stands out among late-2025 flagships [3].

Cameras, displays, and performance metrics

Xiaomi continues its Leica partnership with triple 50MP cameras on the Pro models, including a Light Hunter 950L main sensor and a 5x periscope telephoto on the Pro Max. The Pro Max also stretches the front canvas with a 6.9-inch LTPO AMOLED and carries a 2.9-inch second screen on the back, delivering a literal dual-display experience out of the box.

Under the hood, Snapdragon 8 Elite Gen 5 anchors the series with next-generation CPU and GPU blocks, machine-learning accelerators, and improved power efficiency. That silicon choice aligns with the battery priorities, helping sustain performance while avoiding runaway thermals during camera, gaming, or video workloads.

Gizmochina’s launch rundown confirms the Pro Max bundle: 6.9-inch LTPO AMOLED, 2.9-inch Dynamic Back Display, Snapdragon 8 Elite Gen 5, 7,500mAh battery, 100W wired and 50W wireless charging, Leica 50MP main sensor, 5x periscope, and a ¥5,999 starting price for the 12GB/512GB configuration [4].

Pricing, availability, and global rollout

Xiaomi is segmenting the 17 family clearly. The base Xiaomi 17 starts at ¥4,499, undercutting many premium rivals while delivering a 7,000mAh cell and flagship silicon. The Pro Max’s ¥5,999 entry for 12GB/512GB reflects the second screen, bigger battery, and enhanced camera hardware, representing about a 33% uplift versus the entry price.

Availability in China is rapid. The company announced on September 25 and moved to retail by September 27—an under-48-hour window that pushes inventory into users’ hands fast. Expect early adopters to test real-world battery life and back-display utility almost immediately, shaping demand for storage and RAM tiers.

Android Authority’s prelaunch coverage on September 15 previewed the rear display’s widgets, music controls, animated clocks, and viewfinder functionality, and signposted a global rollout expected in early 2026. That timing would give Xiaomi months to refine software for the back display and gather telemetry on battery and charging behavior before export markets open [5].

How the Xiaomi 17 reshapes flagship priorities for 2026

Design experimentation often fades if it lacks utility, but Xiaomi’s back display targets repeat daily actions—glanceable info, music, timers, and camera framing—rather than novelty. That increases the odds of sustained use, especially when paired with large batteries that blunt any standby hit from an extra screen.

Quantitatively, the lineup also reframes “Pro” trade-offs. The 17 Pro’s 6,300mAh capacity suggests a conscious choice to balance thickness and features, while the base model’s 7,000mAh cell signals endurance-first value. For buyers, the most consequential spec may be capacity per yuan rather than raw speed, given the shared 100W/50W charging.

If rivals follow, 2026 flagships could pivot to bigger cells, faster standard charging, and auxiliary displays tied to camera systems and AI workflows. For Xiaomi, success hinges on software polish and battery management. If the back display becomes a habit, not a gimmick, the company will have validated a new interaction surface for premium phones.
