There is no single, region-neutral Redmi 15 configuration: Xiaomi sells a Redmi 15 4G and a separate Redmi 15 5G. This comparison focuses on the Redmi 15 5G listed by Xiaomi India and the POCO M8 5G listed by Xiaomi Taiwan, while identifying the distinct Redmi 15 4G where it matters. On paper, the Redmi 15 5G emphasizes a larger advertised battery and higher refresh-rate ceiling; the POCO M8 5G pairs an AMOLED display with faster listed charging. The available official prices come from different countries, so they do not establish a direct price difference.
Which Redmi 15 is being compared?
Check the network and processor before treating a listing as the same phone. Xiaomi Belgium’s Redmi 15 page describes the 4G model, powered by Snapdragon 685 with LTE connectivity (Xiaomi Belgium Redmi 15 specifications). Xiaomi India’s separate Redmi 15 5G page identifies Snapdragon 6s Gen 3 and 5G support (Xiaomi India Redmi 15 5G specifications). The POCO compared here is specifically the POCO M8 5G, from Xiaomi Taiwan’s specification page (Xiaomi Taiwan POCO M8 5G specifications).
Because these official pages cover different markets, their specifications should not be combined into a claim about one universal Redmi 15 or POCO configuration. Verify the local model name, network bands, NFC, memory options, protection rating, included accessories and warranty with the seller in your country.
Redmi 15 5G vs POCO M8 5G specifications
| Specification | Redmi 15 5G (India) | POCO M8 5G (Taiwan) |
|---|---|---|
| Processor and network | Snapdragon 6s Gen 3; 5G | Snapdragon 6 Gen 3; 5G |
| Display | 6.9-inch FHD+; up to 144 Hz | 6.77-inch Flow AMOLED; 2392 × 1080; up to 120 Hz |
| Battery capacity | 7000 mAh, advertised by Xiaomi as typical capacity | 5520 mAh, listed as typical capacity |
| Charging | 33 W wired; 18 W reverse charging | 45 W wired; up to 18 W reverse charging listed |
| Main camera information | 50 MP AI dual camera, according to Xiaomi’s product page | 50 MP main camera, according to Xiaomi’s specification page |
| Protection rating | IP64 advertised on Xiaomi India’s product page | Xiaomi Taiwan uses an IP66 headline, but its footnote refers to an IP64 test classification; check the page and local listing for the applicable qualification |
These are manufacturer-listed specifications, not results from independent tests. A larger capacity or a higher refresh-rate maximum does not, by itself, establish longer real-world battery life or a smoother experience in every app.

Which phone has the better battery and charging?
By advertised capacity, the Redmi 15 5G has the larger battery: Xiaomi India lists 7000 mAh typical capacity, compared with 5520 mAh typical capacity for the POCO M8 5G on Xiaomi Taiwan’s page. Those figures are manufacturer specifications; they do not show how long either phone lasts under the same workload.
The POCO lists higher wired charging power at 45 W, versus 33 W for the Redmi. Xiaomi Taiwan says the POCO’s 45 W power adapter is not included and recommends a compatible PD 45 W or official Xiaomi adapter. Package contents can vary by region, so confirm what comes in the box for the exact local model. Both product pages list reverse charging at up to 18 W for the POCO and 18 W for the Redmi.

Which phone has the better display?
The choice depends on which display characteristic matters more. The POCO M8 5G has a 6.77-inch Flow AMOLED panel with a listed resolution of 2392 × 1080 and refresh rates up to 120 Hz. The Redmi 15 5G has a larger 6.9-inch FHD+ display and a higher advertised maximum refresh rate of 144 Hz. Xiaomi’s specifications do not establish which screen is brighter, more color-accurate or easier to read outdoors, so those qualities should not be inferred from size or refresh rate alone.
How much more does one cost?
The official promotional examples available are from different countries and are not a like-for-like comparison. Xiaomi Belgium’s Fan Festival terms listed these Redmi 15 prices; Xiaomi UK’s Fan Festival table listed these POCO M8 5G prices (Xiaomi Belgium promotion terms; Xiaomi UK promotion terms).

These are promotion figures in the cited official terms, not a current universal price or evidence that one model costs a specific amount more. The Redmi promotion page also shows an apparent €0.00 promotional-price anomaly for one purple 6 GB / 128 GB row; that entry is not treated here as a real offer.
To work out a meaningful local difference, compare both phones in the same country and on the same date, with matching storage where possible and equivalent seller, tax and shipping terms. Xiaomi India’s cited Redmi 15 5G page does not provide a price, so the Belgium Redmi prices above should not be presented as prices for that India 5G configuration.

Which should you choose?
- Consider the Redmi 15 5G if its advertised 7000 mAh capacity, larger 6.9-inch screen or up-to-144 Hz refresh-rate ceiling fits your priorities, and the local 5G model and price suit you.
- Consider the POCO M8 5G if you prefer its listed Flow AMOLED display or 45 W wired charging, and you are comfortable checking the charger and regional package details.
- Compare the local listing before deciding if you mean the Redmi 15 4G: it is a different model from the India Redmi 15 5G, with a different processor and network support.
The cited specifications do not include a controlled battery comparison, independent performance benchmarks or hands-on camera testing. They are not enough to name an overall winner or rank camera quality.
