On paper, the Xiaomi Redmi Note 15 listed on Xiaomi’s UAE site has the stronger display and camera specifications, while the OPPO A6x 5G (model CPH2783) has the larger listed battery. Neither phone has a single price or single spec sheet that applies everywhere, so the comparison only holds once you fix the market, the exact model and the RAM and storage configuration.
Start with the variant, not the model name
“Redmi Note 15” covers more than one phone. The official Xiaomi UAE page describes an 8GB + 256GB Redmi Note 15 with a 4G band list, a 6000mAh typical battery and HyperOS 2. An independent Android Central review describes a Redmi Note 15 5G with a Snapdragon 6 Gen 3 chip, a 5520mAh battery, 45W charging and India launch pricing. These are different configurations, not two names for the same handset.

The OPPO side is narrower. The OPPO Global specification page covers the OPPO A6x 5G, model CPH2783, with configurations from 4GB + 128GB to 8GB + 256GB. Its charging and in-box details vary by market.
Before comparing anything, decide three things: the country you are buying in, the exact Redmi Note 15 variant (4G or 5G, and which region) and the RAM and storage you want. Every figure below is tied to the variant named beside it.

Specification comparison
The table sets the Xiaomi UAE listing against the OPPO A6x 5G CPH2783. Where Android Central’s Redmi Note 15 5G figures differ, they are noted in the cell.
| Feature | Redmi Note 15 (Xiaomi UAE listing) | OPPO A6x 5G (CPH2783) | What the difference means |
|---|---|---|---|
| Display | 6.77-inch AMOLED, 2392 × 1080, up to 120Hz | 6.75-inch LCD, 1570 × 720, up to 120Hz | Xiaomi’s listed panel is AMOLED with higher resolution. Both list the same 120Hz ceiling. |
| Rear camera | 108MP main, 2MP depth | 50MP main, 2MP monochrome | Xiaomi lists the higher main-sensor resolution. Megapixel counts do not measure photo quality. |
| Front camera | 20MP | 5MP | Xiaomi lists the higher front resolution. No side-by-side camera test is available from these sources. |
| Chipset | Not stated on the Xiaomi UAE listing; the Redmi Note 15 5G reviewed by Android Central uses Snapdragon 6 Gen 3 | MediaTek Dimensity 6300 | Do not assume the UAE 4G model shares the 5G India model’s chip. |
| Battery | 6000mAh typical (UAE listing); 5520mAh (5G India model, Android Central) | 6500mAh typical; 6335mAh rated | OPPO’s listed capacity is larger against either Xiaomi variant. Capacity does not prove longer real-world battery life. |
| Charging | 33W turbo charging, 33W charger in box (UAE listing); 45W (5G India model, Android Central) | Fast charging not supported; charger in box, depending on market | Xiaomi lists the faster charging on both variants. Charging times are not established by these sources. |
| Mobile network | 4G, 3G and 2G bands on the UAE listing | 5G NR bands listed for CPH2783 | These are not network-equivalent. Confirm 5G bands with your carrier before buying. |
| Software | HyperOS 2 | ColorOS 15.0 | Both are the versions stated on the official pages. Updates and regional builds can differ. |
| Storage and expansion | 8GB + 256GB on the UAE listing; microSD via hybrid SIM slot, expansion up to 2TB stated | 4GB + 128GB to 8GB + 256GB; storage card supported | Match RAM and storage before comparing prices. |
| Water and dust protection | IP64, with Xiaomi’s laboratory and warranty caveats | No IP rating stated in the cited specification | Neither phone should be described as waterproof on these figures. |
What the specifications mean in practice
Display
The UAE Redmi Note 15 has the better screen on paper: AMOLED at 2392 × 1080 against the A6x’s LCD at 1570 × 720. AMOLED usually gives deeper blacks and sharper text, but the listed numbers do not measure brightness, colour accuracy or outdoor visibility, so judge the panel by hands-on viewing if those matter to you.

Cameras
Xiaomi lists 108MP main and 20MP front cameras; OPPO lists 50MP main and 5MP front. Higher resolution does not guarantee better images, because sensor size, processing and lighting conditions drive results. The OPPO’s 2MP monochrome sensor and the Xiaomi’s 2MP depth sensor are supporting units, not comparable main cameras.

OPPO’s 6500mAh typical figure is the largest battery capacity in this comparison, and it beats both the UAE Xiaomi (6000mAh typical) and the 5G India Xiaomi (5520mAh). Xiaomi, however, lists 33W turbo charging on the UAE model and 45W on the 5G India model, while OPPO states that fast charging is not supported. Speed and endurance depend on use, screen settings and charger, so neither spec sheet tells you how long a full charge takes.

Network and 5G
The UAE Redmi Note 15 is listed with 4G, 3G and 2G bands. The OPPO A6x 5G CPH2783 is listed with 5G NR bands. If 5G is a requirement, the Xiaomi variant you are looking at must be the 5G model, and you should check its band list against your operator.
Storage, software and protection
The Xiaomi UAE listing states 8GB + 256GB and microSD expansion up to 2TB. The OPPO configurations run from 4GB + 128GB to 8GB + 256GB, with a storage card supported. Both list their software versions (HyperOS 2 and ColorOS 15.0). Xiaomi lists IP64 protection, subject to caveats; OPPO’s cited specification does not state an IP rating.

Price difference: what the figures do and do not show
There is no single, verified price gap between these two phones. The available figures come from different sources, dates and configurations, so they cannot be subtracted from each other.

Retailer listings (91mobiles comparison page, 2026)
A 91mobiles comparison page, accessed in 2026, displayed ₹28,999 for the Xiaomi Redmi Note 15 and ₹18,999 for the OPPO A6x, both with Amazon labels. These are India retailer snapshots, not confirmed current prices, and the page does not clearly match RAM, storage or network variant. The same page also contains specifications that conflict with the manufacturer pages, so use it only as a dated price reference.

Launch prices (Android Central, 2026)
Android Central reported India launch prices of ₹22,999 for the starting Redmi Note 15 5G and ₹24,999 for the 8GB + 256GB version. These are launch prices, not current street prices, and they apply to the 5G model rather than the UAE 4G listing.
How to get a usable price comparison
- Pick one country and one Redmi Note 15 variant (4G UAE model or 5G India model).
- Pick the same RAM and storage for both phones.
- Check official or authorised retailer prices on the same day, and note the seller, currency and tax basis.
- Record the date beside the price. Prices in these sources moved between launch and the 2026 listings.
Which phone fits which priority
- Display and photo resolution: the Xiaomi UAE Redmi Note 15 leads on listed AMOLED resolution, main camera megapixels and front camera megapixels.
- Battery capacity and 5G: the OPPO A6x 5G CPH2783 leads on listed battery capacity and confirms 5G NR bands.
- Charging speed: the Xiaomi variants list faster charging (33W on the UAE model, 45W on the 5G India model) than OPPO, which lists no fast charging.
- Best overall value: this depends on the price you can confirm in your market for the matched configuration.
This is a comparison of published specifications. It does not establish which phone has better measured battery life, photos or performance.
