The POCO X8 is the better fit if you prioritize a much larger battery and display; the POCO X7 is slimmer, lighter, offers an ultrawide camera and macro camera, and records rear video at up to 4K. A fair current price difference cannot be established from the available UK listings: Xiaomi showed the X8 at £269, while its X7 FAQ lists older entry prices rather than a current matched offer.

See Xiaomi’s POCO X7 specifications and POCO X8 specifications for region-specific details. The official global product name is POCO X8, although “POCO X8 5G” is common comparison wording.
Which phone has the better price?
There is no reliable current, like-for-like price difference in the available UK figures. Xiaomi’s UK storefront displayed the X8 at £269 against a £329 marketing price when checked on October 7, 2026. Xiaomi’s X7 FAQ reports entry prices of £199 for 8GB/256GB and £229 for 12GB/512GB, but tells shoppers to check the store for current prices and offers. Those X7 figures are not current quotes, and the storage tiers do not match the X8’s £269 listing. Check Xiaomi UK’s current POCO listings and compare the same market and storage tier on the same day. Prices and availability outside the UK are not established here.

Which is easier to hold and use?
The X7 is substantially lighter: 185.5g in the plastic version or 190g in the PU version, versus 223g for the X8. The X8 is also 3.85mm wider and has a 6.83-inch display rather than the X7’s 6.67-inch screen. Both list 1.5K-class resolution and refresh rates up to 120Hz, but the X8’s larger screen and extra weight may be less comfortable for one-handed use or long periods of holding. Xiaomi’s peak-brightness figures are manufacturer claims, not measurements from a shared independent test.
Battery capacity and charging: what the figures tell you
Xiaomi lists a typical 8340mAh battery and 67W HyperCharge for the X8, compared with a typical 5110mAh battery and 45W turbo charging for the X7. Those capacity and charging-rate specifications favor the X8 on paper, but they do not establish how many hours either phone lasts in everyday use or how long each takes to charge under the same conditions.

The X8 also lists wired reverse charging up to 22.5W. Xiaomi describes the X8 battery as silicon-carbon and advertises battery-life claims and a “60-month like-new software experience” on its product page; that marketing language is not an independent longevity result or a promise of 60 months of operating-system or security updates. See Xiaomi’s POCO X8 product page.

The X7 has more rear-camera options: a 50MP OIS main camera, an 8MP ultrawide, and a 2MP macro camera. Its listed rear video modes reach 4K at 30fps. The X8’s global specification lists a 50MP OIS main camera and a 2MP depth camera, with rear video recording up to 1080p at 30fps. If you want an ultrawide lens, a dedicated macro module, or the higher listed rear-video resolution, the X7 has the more flexible specification set. Camera counts and megapixels alone do not establish which phone takes better photos.

Performance, memory, and storage
The X7 uses a MediaTek Dimensity 7300-Ultra, while the X8 lists a Snapdragon 6s Gen 4. Both chips are specified as 4nm; the X7 page lists up to 2.5GHz and the X8 page up to 2.4GHz. These published details are not enough to determine which phone performs better in games or everyday tasks, and there is no comparable benchmark test in the cited specifications.
Storage choices differ. The X7 page lists 8GB/256GB and 12GB/512GB; the X8 global page lists 6GB/128GB, 8GB/256GB, and 12GB/256GB. Buyers who need the largest listed capacity will find 512GB on the X7 page, while the X8 adds a lower-cost-looking 6GB/128GB configuration—but actual availability and price depend on region.

Check regional details before buying
- Carrier bands: Both phones support 5G, and Xiaomi lists network bands on each specification page. Confirm the exact regional model supports the bands used by your carrier before purchasing; 5G support by itself does not guarantee compatibility.
- Power adapter: The X8 global page says the box does not include a power adapter and recommends a compatible 67W PD adapter or Xiaomi 67W adapter; it warns that box contents may vary by region. Xiaomi’s UK X7 specification page also says no adapter is included and recommends 45W PD or Xiaomi 67W-or-higher adapters. Check the actual regional box and charging compatibility before buying an extra adapter.
- Water and dust claims: The X7 page lists IP68, while the X8 page lists IP66/IP68/IP69/IP69K claims with specified test conditions and caveats. These ratings are bounded by manufacturer conditions; do not treat them as an invitation to recreate laboratory tests or as a guarantee against every kind of exposure.
Which one should you choose?
- Choose the POCO X7 if you prefer a lighter, narrower phone, want an ultrawide and macro camera option, value the listed 4K/30fps rear video mode, or need the X7 page’s 512GB configuration.
- Choose the POCO X8 if you want the larger display, the higher listed battery capacity and charging rate, or its 12GB/256GB global configuration. Be prepared for its greater weight and wider body.
- Wait to compare current listings if price is decisive. Use same-day prices for the same market and, where possible, the same storage tier; the available UK figures do not establish a current X7–X8 price gap.
