Poco X7 Pro vs Xiaomi 15

Poco X7 Pro

The 6.67-inch AMOLED display punches well above its price class with 1220x2712 resolution, 120Hz refresh, 12-bit color depth, and an astounding 3,200 nits peak brightness. Dolby Vision and HDR10+ support make it excellent for media consumption.

• 3,200 nits peak brightness with Dolby Vision and HDR10+ — flagship-level at a budget price
• 1220x2712 resolution at 120Hz with 12-bit color depth — sharper than most phones in its class
• No LTPO means limited refresh rate granularity — either 60Hz or 120Hz

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

Poco X7 Pro

The Dimensity 8400-Ultra is the fastest mid-range chipset of 2025, rivaling the Snapdragon 8s Gen 3. Gaming performance is exceptional — PUBG runs at 118fps with 100% smoothness, and LiquidCool 4.0 vapor chamber cooling helps sustain performance during extended sessions.

• Dimensity 8400-Ultra scores ~1.83 million on AnTuTu — fastest in its price class by a significant margin
• PUBG at 118fps average with 100% smoothness — best gaming experience under $400
• 8GB RAM variant has aggressive RAM management — apps killed in background causing missed notifications

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

Poco X7 Pro

The 50MP main camera with Sony IMX882 delivers good daylight photos with faithful colors and wide dynamic range. The 2x in-sensor zoom works well. However, the 8MP ultrawide is significantly weaker with muddy results, and the 20MP selfie camera is particularly poor — effectively upscaled from 5MP.

• 50MP main sensor delivers good detail, low noise, and faithful colors in daylight conditions
• 2x in-sensor zoom is a useful upgrade from the predecessor — surprisingly capable
• 8MP ultrawide delivers significantly weaker results — low detail and muddy output
• 20MP selfie camera is effectively upscaled from 5MP — one of the worst at any price point

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

Poco X7 Pro

The 6,000mAh battery provides excellent all-day endurance with 6-9 hours of real-world screen-on time. 90W HyperCharge does 0-100% in about 46 minutes. Expert Reviews measured 21 hours 43 minutes in their looping video test. The charger is included in the box in some markets.

• 6,000mAh battery delivers 6-9 hours SOT depending on usage — excellent for the price class
• 90W HyperCharge goes from 0-100% in approximately 46 minutes — 90W charger included in some markets
• Some users report battery drain issues with weak 5G or Wi-Fi signal

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

Poco X7 Pro

HyperOS 2.0 on Android 15 with 3 OS updates and 4 years of security patches (through 2029). The UI is smooth with nice animations once set up, but the out-of-box experience is marred by heavy bloatware (~8 preinstalled games, TikTok, ads in the lock screen) that requires significant cleanup.

• HyperOS 2.0 is smooth and fluid with nice animations once debloated — functional day-to-day experience
• Heavy bloatware out of box: ~8 preinstalled games, TikTok, WPS Office, ads in system UI notifications
• Requires approximately 30 minutes of manual debloating after first boot for a clean experience

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
