Xiaomi 15 vs Xiaomi 15 Pro

Xiaomi 15

The 6.36-inch 1.5K LTPO OLED is sharp, vibrant, and incredibly bright at 3,200 nits peak (tested up to 3,593 nits HDR). Ultra-narrow 1.38mm bezels and high-frequency PWM dimming above 3,000Hz round out an excellent display package, though OLED smear at lower brightness is a noted concern.

• Peak brightness tested at 3,593 nits in HDR — among the brightest compact phone displays available
• Ultra-narrow 1.38mm bezels with excellent color accuracy in Original Color PRO profile
• OLED smear visible at lower brightness levels (0-70% range) — a recurring user complaint

Xiaomi 15 Pro

The 6.73-inch 2K LTPO AMOLED is a technical marvel, hitting 3,200 nits peak brightness while consuming 24% less power than the Xiaomi 14 Pro's display. The 1920Hz PWM dimming reduces eye strain, though some users report OLED smear at low brightness levels.

• 3,200 nits peak brightness with 24% lower power consumption than the predecessor — outstanding efficiency
• 2K resolution (2670x1200) with 120Hz LTPO and 1920Hz PWM dimming for reduced eye strain
• Reports of OLED smear/ghosting at lower brightness levels when scrolling dark content

Xiaomi 15

The Snapdragon 8 Elite with 12GB RAM delivers flagship-tier performance that's smooth and snappy for everyday use, gaming, and multitasking. However, the compact body struggles to dissipate heat under sustained loads, causing notable thermal throttling during extended gaming sessions.

• Snapdragon 8 Elite scores ~2,990 single-core and ~9,114 multi-core on Geekbench 6 — genuinely fast
• Thermal throttling is a real issue — fails to complete 3DMark GPU stress tests and gets uncomfortably hot
• CPU throttles to 72-77% of peak under sustained load — compact chassis limits cooling capacity

Xiaomi 15 Pro

The Snapdragon 8 Elite (3nm) delivers a 44% single-core improvement over the previous generation and manages thermals better than most competitors. NotebookCheck awarded a 99% application performance score, placing it among the fastest phones available.

• Snapdragon 8 Elite achieves Geekbench 6 single-core of 3,157 — a 44.4% leap over Snapdragon 8 Gen 3
• Better thermal management and sustained performance than competitors like the Oppo Find X8 Pro
• Some throttling under prolonged heavy gaming loads, though managed better than peers

Xiaomi 15

The triple 50MP Leica system shines with its main sensor and improved 2.6x telephoto, earning a DxOMark score of 146. Leica color profiles produce natural, pleasing images with excellent dynamic range. The ultrawide camera is the clear weakness, with noticeably more noise in low light and no autofocus.

• 50MP main Leica Summilux camera delivers excellent photo quality with natural colors and strong dynamic range
• 2.6x optical telephoto is a meaningful upgrade over the Xiaomi 14 — sharp and versatile
• Ultrawide camera is the weakest link — subpar quality, no autofocus, noticeably more noise in low light
• DxOMark camera score of 146 — good but not class-leading among 2025 flagships

Xiaomi 15 Pro

The triple 50MP Leica Summilux system delivers solid results with a standout 5x periscope telephoto. The main sensor with f/1.44 aperture handles most scenarios well, and AI Zoom makes 20x digital shots usable. However, the ultrawide is the clear weak link, and the system can't quite match the Vivo X200 Pro's imaging prowess.

• 5x periscope telephoto (120mm) delivers sharp, detailed results up to 10x — AI Zoom usable at 20x
• Main 50MP sensor with f/1.44 aperture and Leica color science produces pleasing, natural-looking images
• Ultrawide camera (50MP JN1) is the weakest lens — frequently criticized by users as noticeably below main and telephoto quality
• Camera scored 82% on NotebookCheck — the lowest individual category score, behind the Vivo X200 Pro

Xiaomi 15

A standout category for the Xiaomi 15. The 5,400mAh silicon-carbon battery is a huge upgrade from the Xiaomi 14's 4,610mAh, delivering 16+ hours of active use in GSMArena's tests and consistently 7-8 hours of screen-on time. 90W wired charging goes from 0-100% in about 50 minutes.

• GSMArena Active Use Score of 16:28 hours — excellent endurance for a compact flagship
• 5,400mAh silicon-carbon battery is a massive upgrade from the Xiaomi 14's 4,610mAh — real-world 7-8 hours SOT
• 90W wired charging does 0-100% in about 50 minutes; 50W wireless charging also supported

Xiaomi 15 Pro

The 6,100mAh silicon-carbon battery combined with the ultra-efficient display delivers class-leading endurance. NotebookCheck awarded a 93% battery score, and the phone consumes dramatically less power than its predecessor (4.42W vs 6.17W for display). 90W wired and 50W wireless charging round out the package.

• 6,100mAh silicon-carbon battery delivers class-leading endurance — competitors consume more than twice as much energy
• 90W wired HyperCharge and 50W wireless charging provide fast top-ups
• Display consumes just 4.42W vs the Xiaomi 14 Pro's 6.17W — a 24% improvement in power efficiency

Xiaomi 15

HyperOS 2 based on Android 15 is fast and fluid with snappy animations and useful AI features. Xiaomi promises 4 major OS updates and 5-6 years of security patches. However, bloatware remains a persistent concern with 193+ removable packages identified, and some system apps contain advertisements.

• HyperOS 2 is fast, fluid, and full of character — one of the more polished Android skins in 2025
• 4 major OS updates + 5-6 years of security patches — competitive but behind Samsung's 7-year commitment
• Significant bloatware with 193+ identifiable packages — some system apps contain advertisements

Xiaomi 15 Pro

HyperOS 2 based on Android 15 brings improved fluency over HyperOS 1 and is now receiving the HyperOS 3/Android 16 update. However, the Chinese ROM lacks Google services out of the box, and the community considers HyperOS bloated with unnecessary apps compared to stock Android.

• HyperOS 2 offers "substantially improved fluency and stability" over the first version
• Chinese ROM only — no Google services out of the box, no Android Auto, limited language support
• HyperOS described as "full of unnecessary apps" — bootloader cannot be unlocked on Chinese ROM
