For India, the OPPO K13x 5G is the stronger fit if you want 5G, higher-resolution cameras, more storage in the base configuration and 45W charging included. The India OPPO A6x discussed here is model CPH2819, an LTE phone with a larger-capacity battery but no supported fast charging. A current, like-for-like price difference cannot be established from the available dated prices, so treat the K13x figures below as launch prices—not today’s quotes.
Which OPPO A6x does this comparison cover?
“A6x” is used for regionally different configurations. This comparison is specifically between the OPPO K13x 5G sold in India and the India OPPO A6x model CPH2819. OPPO’s India specification pages identify these models and their features: K13x 5G specifications and A6x specifications. Do not assume another country’s A6x has the same network support, memory or other specifications.
OPPO K13x vs OPPO A6x: key specifications
| Specification | OPPO K13x 5G (India) | OPPO A6x CPH2819 (India) |
|---|---|---|
| Mobile network | 5G | GSM, WCDMA and LTE bands listed; no 5G listed by OPPO |
| Processor | MediaTek Dimensity 6300 | Qualcomm Snapdragon 685 |
| Listed memory and storage options | 4GB/128GB, 6GB/128GB and 8GB/128GB | 4GB/64GB |
| Display | 6.67-inch HD+ LCD, up to 120Hz | 17.15cm (about 6.75-inch) HD+ LCD, 1570 × 720, up to 120Hz |
| Rear cameras | 50MP main and 2MP secondary | 13MP wide-angle and QVGA monochrome |
| Front camera | 8MP | 5MP |
| Battery | 6000mAh | 6500mAh typical; 6335mAh rated |
| Charging | 45W SUPERVOOC; OPPO says a 45W charger is included | Fast charging listed as unsupported |
Specifications are from OPPO’s India pages linked above. OPPO notes that specifications may vary by region, software version, suppliers and actual use. A shared HD+ LCD resolution and maximum 120Hz refresh rate do not by themselves establish which screen looks better.
Does the OPPO A6x support 5G?
Not the India A6x CPH2819 in this comparison: OPPO’s official specifications list GSM, WCDMA and LTE bands, but not 5G. The K13x is explicitly sold in India as the K13x 5G. Check the model number and network bands for an A6x sold in another region rather than applying CPH2819’s specifications to it.

Which phone has the better performance and storage?
The processor names alone do not settle real-world speed: the available evidence does not establish an independent head-to-head performance result. For capacity, however, the listed India configurations favor the K13x. Its base model has 128GB storage, twice the A6x CPH2819’s listed 64GB, and OPPO offers K13x memory options up to 8GB RAM. Choose based on the storage you need as well as the applications you use; a processor label is not a substitute for a direct performance test.
Which has the better battery and charging?
The A6x CPH2819 has the larger stated battery: 6500mAh typical (6335mAh rated), against the K13x’s 6000mAh. Capacity is not a measured runtime comparison, so it does not prove that the A6x lasts longer in everyday use. OPPO says the K13x supports 45W SUPERVOOC and includes a 45W charger in the box; it also says an anti-drop shield case is included.

OPPO’s K13x launch materials claim over 80% battery health after 1,700 charge cycles and up to 19.3 hours of video playback. These are manufacturer claims, not independent comparative test results. OPPO’s A6x product page describes a five-year battery-capacity projection above 80%, based on OPPO laboratory testing and an assumed once-daily charge; it is a projection, not a guaranteed outcome for an individual phone. See OPPO India’s A6x product page for the manufacturer’s description.
Which phone has the better cameras?
The K13x has higher stated camera resolutions: a 50MP main rear camera and 8MP front camera, versus the A6x CPH2819’s 13MP rear wide-angle and 5MP front cameras. Both list an additional rear camera—the K13x a 2MP secondary camera and the A6x a QVGA monochrome camera. Megapixel counts do not establish image quality, and no independent side-by-side camera test is available here. If photography is your deciding factor, do not treat the larger number alone as proof of better photos.

What is the OPPO K13x vs A6x price difference?
OPPO India announced the K13x on June 23, 2025, at these launch prices. They are historical launch prices, not current retailer quotes.
| K13x India configuration | Launch price announced June 23, 2025 |
|---|---|
| 4GB + 128GB | ₹11,999 |
| 6GB + 128GB | ₹12,999 |
| 8GB + 128GB | ₹14,999 |
The launch announcement also described conditional sale-day discounts of ₹1,000 or ₹2,000; those were offers tied to that sale, not enduring prices. OPPO’s A6x CPH2819 specification page does not state a price, and no reliable same-date price for a matched A6x configuration is established here. The listed A6x configuration is 4GB/64GB, while all listed K13x configurations have 128GB, so even current prices need configuration context. Check current India retailer listings for the exact model, storage, seller, stock and date before deciding which costs less.

Which one should you choose?
- Choose the K13x 5G if 5G support, 128GB base storage, a higher-resolution camera specification or included 45W charging matters most.
- Consider the A6x CPH2819 if its larger stated battery capacity suits your priorities and LTE is sufficient for your use.
- Compare live prices carefully because the launch prices above are dated and the listed phones do not have matching storage configurations.
