The realme 16 5G is the smaller, lighter option in this comparison; the POCO X8 Pro Max has the stronger listed spec sheet, with a larger, sharper display, a higher-tier chipset, and a larger stated battery. The POCO also costs more in the dated Brazil and India listings available here. The right choice depends on your country, current local pricing, and whether you prefer a more compact phone or the POCO’s larger-screen hardware.
At a glance: the main differences
| Specification | realme 16 5G | POCO X8 Pro Max |
|---|---|---|
| Display | 6.57-inch, 1080 × 2372, 120 Hz, according to Oficina da Net | 6.83-inch AMOLED, 2772 × 1280, up to 120 Hz; Xiaomi UK specification |
| Chipset | MediaTek Dimensity 6400 Turbo, according to Oficina da Net | MediaTek Dimensity 9500s, according to Xiaomi UK |
| Memory and storage | 128 GB or 256 GB storage listed by Oficina da Net; RAM not established in the cited listings | 12 GB RAM and 256 GB or 512 GB storage, according to Xiaomi UK |
| Rear cameras | Not established by the cited sources | 50 MP main with OIS and 8 MP ultrawide, according to Xiaomi UK |
| Front camera | Not established by the cited sources | 20 MP, according to Xiaomi UK |
| Battery | Conflicting listings: Oficina da Net says 6,550 mAh; Smartprix says 7,000 mAh | 8,500 mAh typical capacity, according to Xiaomi UK |
| Wired charging | Not established by the cited sources | 100 W charging and up to 27 W wired reverse charging; Xiaomi says actual output varies |
| Size and weight | 158.3 × 75.1 × 8.1 mm and 181 g, according to Oficina da Net; Smartprix lists 183 g | Dimensions and weight not established by the cited source |
These are reported specifications, not results from hands-on testing. The Realme battery figures conflict, and the exact Realme weight differs between comparison listings, so neither should be treated as settled without checking the official specification for your market.
Which phone has the better display?
The POCO has the larger panel: Xiaomi UK lists a 6.83-inch AMOLED display at 2772 × 1280 with a refresh rate up to 120 Hz. Oficina da Net lists the realme 16 5G at 6.57 inches, 1080 × 2372, and 120 Hz. On those published numbers, the POCO offers more screen area and higher resolution; both are listed at up to 120 Hz.

Xiaomi also specifies peak brightness of 3,500 nits over 25% of the display area and 2,000 nits in HBM mode. Those figures describe different conditions and cannot be compared fairly with a brightness number for another phone unless the measurement method and conditions match.

How do performance, memory, and storage compare?
Oficina da Net lists a MediaTek Dimensity 6400 Turbo for the Realme, while Xiaomi UK lists a Dimensity 9500s for the POCO. That places the POCO in a higher chipset tier on paper, but these specifications alone do not establish how much faster it is in games or everyday use. No comparable benchmark results are established here.
Xiaomi UK lists the POCO with 12 GB of RAM and either 256 GB or 512 GB of storage. Oficina da Net lists the Realme with 128 GB or 256 GB storage, but the cited Realme listings do not establish a comparable RAM configuration. Check the exact local variant before buying, since memory and storage options can differ by market.
What do the camera specifications establish?
Xiaomi UK lists a 50 MP main rear camera with optical image stabilization (OIS), an 8 MP ultrawide camera, and a 20 MP front camera for the POCO. The cited comparison listings do not provide enough reliable Realme camera detail for a like-for-like specifications table.

How large is the battery difference?
Xiaomi UK gives the POCO an 8,500 mAh typical-capacity battery. For the realme 16 5G, Oficina da Net lists 6,550 mAh, while Smartprix lists 7,000 mAh. Because those reported Realme capacities conflict, the gap should not be calculated as though one figure were definitive.
Xiaomi lists 100 W wired charging and up to 27 W wired reverse charging for the POCO, and notes that actual output varies. Its UK product page also says an adapter is not included in the box. The cited sources do not establish Realme charging speed or charger contents. A larger stated battery does not, by itself, prove longer runtime: screen use, software, network conditions, and testing methods affect endurance. TechRadar’s April 3, 2026 headline called the POCO “The longest-lasting phone I’ve ever reviewed”; that is the reviewer’s subjective headline, not a standardized battery-life figure.
Which phone is smaller and lighter?
Oficina da Net lists the realme 16 5G at 158.3 × 75.1 × 8.1 mm and 181 g. Smartprix lists its weight as 183 g, so the listings do not agree exactly. The available Xiaomi UK specification cited here does not establish the POCO’s dimensions or weight. The Realme’s reported size and weight support calling it the smaller option in this comparison, but a precise size or weight difference cannot be stated from these sources.

How do the listed prices compare by country?
Prices below are listings from comparison pages, not guaranteed current retailer offers. The pages report different release dates for the Realme, and listed prices can change with stock, configuration, promotions, and location.

| Market and source | realme 16 5G | POCO X8 Pro Max |
|---|---|---|
| Brazil — Oficina da Net comparison listing | Current listed price R$2,999; launch price R$2,499 | Current listed price R$3,172; launch price not shown |
| India — Smartprix comparison listing, details last updated September 30, 2026 | Lowest listed price ₹35,499 | Lowest listed price ₹48,999 |
| UK/US launch-era context — TechRadar, April 3, 2026 | Not stated | Started at $469 / £469; the base model had 12 GB RAM and 256 GB storage at the time of writing |
In the cited Brazil listing, the displayed current prices differ by R$173. In the cited India listing, they differ by ₹13,500. Both are arithmetic differences between dated listings, not universal price gaps or assurances of today’s retail price. The TechRadar figure is launch-era context, not a current UK or US price.
The comparison pages also give different Realme release dates: January 29, 2026 on the Brazil page and April 2, 2026 on Smartprix’s India page. These may reflect regional release timing, but the difference is unresolved. Both pages list March 17, 2026 for the POCO.

Choose the POCO X8 Pro Max if
- You want the larger, higher-resolution display listed in the specifications.
- You prioritize the higher-tier listed chipset and a clearly stated 12 GB RAM configuration.

The cited sources do not establish reliable Realme update-support or warranty terms, so check the manufacturer’s regional documentation and local seller before purchase.
