The comparison is clearest when the Xiaomi model is identified as the REDMI Note 15 5G. Its official global specifications confirm a 6.77-inch AMOLED display, Snapdragon 6 Gen 3, 108 MP main camera, 5,520 mAh battery, 45 W charging, and IP66 rating. The Galaxy A37 comparison listings describe a 6.7-inch 120 Hz AMOLED display, Exynos 1480, 5,000 mAh battery, and IP68 rating, but these figures need confirmation against Samsung’s exact regional model. Prices in the available comparisons conflict, so they do not establish a dependable current price gap.
There are also Redmi Note 15 4G and 5G variants. Treat their specifications as separate: the table below uses Xiaomi’s official 5G information where available and labels Galaxy A37 details as comparison-site reports, not manufacturer-confirmed specifications.
Redmi Note 15 5G vs Galaxy A37 5G: at a glance
| Specification | Xiaomi REDMI Note 15 5G | Samsung Galaxy A37 5G |
|---|---|---|
| Evidence and model scope | Xiaomi’s official global product page | Comparison-site listings; verify against the exact Samsung regional SKU |
| Display | 6.77-inch FHD+ AMOLED; refresh rate not stated on the cited official page | 6.7-inch 120 Hz AMOLED/Super AMOLED, as reported by comparison sites |
| Processor | Snapdragon 6 Gen 3 | Exynos 1480, as reported by comparison sites |
| Main rear camera | 108 MP with optical image stabilization | 50 MP with optical image stabilization, as reported by comparison sites |
| Other rear cameras | 8 MP ultra-wide | 8 MP ultra-wide and 5 MP macro, as reported by comparison sites |
| Battery and charging | 5,520 mAh silicon-carbon; 45 W charging; 18 W reverse charging | 5,000 mAh and 45 W charging, as reported by comparison sites |
| Dust and water rating | IP66 | IP68, as reported by comparison sites |
| Weight and thickness | 178 g; 7.35 mm | Not established by the cited sources for a verified regional SKU |
| Price | No reliable current, matched-market price established | No reliable current, matched-market price established |
The Xiaomi figures come from its official REDMI Note 15 5G specifications. Galaxy A37 specifications above are reported by Aramobi’s comparison and Inside-digital’s comparison; neither source establishes that every figure applies to the same regional SKU.

Display and performance
The official Xiaomi page specifies a larger 6.77-inch FHD+ AMOLED panel, while comparison listings put the Galaxy A37 at 6.7 inches and 120 Hz. The sources do not state a refresh rate for Xiaomi in the cited official specification, so the available evidence does not support a direct refresh-rate verdict. The listed chipsets—Snapdragon 6 Gen 3 for Xiaomi and Exynos 1480 for Samsung—are model names, not a substitute for comparable independent performance tests.

Cameras
Xiaomi’s official listing pairs a 108 MP stabilized main camera with an 8 MP ultra-wide. The comparison pages list a 50 MP stabilized main camera, 8 MP ultra-wide, and 5 MP macro for the Galaxy A37. Megapixel counts alone do not determine photo quality, and the Samsung details should be checked against its exact regional product listing before treating this as a definitive camera comparison.
Battery, charging, and durability
Xiaomi states a 5,520 mAh silicon-carbon battery, 45 W wired charging, and 18 W reverse charging for the 5G model. Its page also claims five-year long-life battery performance and survival of a 1.7 m face-down drop onto marble; these are manufacturer claims, not independent test results. Comparison sites list 5,000 mAh and 45 W charging for the Galaxy A37.

The reported IP66 rating for Xiaomi and IP68 for Samsung describe different levels of dust and water protection under specified test conditions. Neither rating makes a phone damage-proof, and real-world resistance can decline with wear or damage. Xiaomi’s figure is confirmed on its official 5G page; Samsung’s comparison-site rating still needs verification for the intended SKU.

Pick the symptom - the matching free tool is one click away.
What is the price difference?
The available sources do not support a trustworthy current price difference. One comparison gives initial global price references of €290 / $340 for Xiaomi and €280 / $330 for Samsung. Another lists German suggested prices of €199.90 for Redmi Note 15 and €429 for Galaxy A37. Those figures conflict and may refer to different regions, storage configurations, or source data; they are not current quotes and should not be subtracted to claim a universal saving.

For a meaningful comparison, check both phones in the same country and on the same date, using the same storage tier and comparable seller terms. Record the exact regional model code and whether each figure is a list price or a temporary offer. Only then calculate the difference.
Check these details before choosing
- Redmi variant: Confirm whether the listing is the Redmi Note 15 5G or 4G. Do not transfer specifications between variants.
- Regional model and network: Verify each phone’s exact SKU, 4G/5G support, and compatibility with your carrier’s local bands.
- Memory configuration: Match RAM and internal storage when comparing prices; the inspected listings do not establish one like-for-like configuration.
- Samsung specifications: Confirm the display, chipset, camera setup, battery, charging, and IP rating against Samsung’s product information for your region.
- Software and expansion: Check the seller or manufacturer listing for the software version, update-support terms, and microSD support for the exact model; the cited sources do not settle these details consistently.
- Physical fit: Compare dimensions and weight for the exact regional models if pocketability or case compatibility matters.
Which phone should you buy?
Choose between specific regional models and current matched offers, not names alone. Xiaomi’s official specifications make the REDMI Note 15 5G’s core hardware easier to verify: it has a 108 MP stabilized main camera, 5,520 mAh battery, and 45 W charging. The Galaxy A37 comparison listings suggest a 120 Hz display and IP68 rating, but confirm those features on Samsung’s regional SKU before using them to decide. If price is the deciding factor, compare the same storage configuration from sellers in your country on the same day; the published reference prices are too inconsistent to establish which is cheaper.
