For the India models, the OPPO K13 5G (CPH2729) has the stronger listed display, memory and charging specifications; the OPPO A6s 5G (CPH2889) has a slightly larger screen, a headphone jack and a newer Bluetooth version. At launch, the A6s cost ₹1,000 more at base—but its base configuration had half the K13’s RAM. These are historical launch prices, not confirmed current retail prices.
Check the model code before comparing: OPPO also lists an A6s 5G CPH2789 for other markets, with different specifications. This comparison uses India’s CPH2889.

Which phone has the better display?
K13: sharper AMOLED
The K13’s 6.67-inch FHD+ AMOLED panel has a listed resolution of 1080×2400 and density of 394ppi. It supports refresh rates up to 120Hz. Its higher resolution and AMOLED panel make it the stronger display specification on paper.

A6s: a little larger, but lower resolution
The A6s screen measures 17.15cm diagonally—slightly larger than the K13’s 16.94cm—but it is an HD+ LCD with 1570×720 resolution and 256ppi. It also lists refresh rates up to 120Hz, so both phones specify the same maximum refresh rate; that does not make their panel types or sharpness equivalent.
Performance, RAM and storage
The K13 lists a Qualcomm Snapdragon 6-series platform, 8GB of LPDDR4X RAM and UFS 3.1 storage. The A6s lists a Dimensity 6300, 4GB or 6GB of LPDDR4X RAM and UFS 2.2 storage. On the published memory and storage specifications, the K13 offers more RAM and a higher storage class, as well as a 256GB option.
Those specifications alone do not establish how much faster one phone feels in everyday use or gaming. No comparative benchmark results are established here, so a performance ranking beyond the listed configurations would be unsupported.

Battery and charging differences
OPPO lists a typical 7,000mAh battery and 80W SUPERVOOC charging for the K13, compared with a typical 6,500mAh battery and 45W SUPERVOOC for the India A6s. The K13 therefore has the larger stated capacity and higher charging wattage. Typical and rated capacities are not the same measure, and neither capacity nor charging wattage proves comparative real-world battery life or charging time.
Camera and video specifications
Both phones list a 50MP autofocus main rear camera and a 2MP monochrome camera. The K13’s specification explicitly includes EIS on its main camera; the A6s listing does not. Their front-camera specifications differ: 16MP, f/2.4 on the K13 and 5MP, f/2.2 on the A6s.
The K13 lists rear video recording up to 4K at 30fps, with EIS options up to 1080p/60fps. The A6s lists rear video up to 1080p/60fps, with some limits for its 4GB variant. Resolution and sensor figures do not establish which phone takes better photos or video; that requires comparative testing.

Launch prices and the ₹1,000 difference
OPPO India announced K13 pricing on April 21, 2025, with sales beginning April 25. The A6s launch announcement, dated March 18, 2026, listed its prices below. The A6s’s base launch price was ₹1,000 higher, but the base models are not a like-for-like RAM comparison.
| Phone and configuration | India launch price |
|---|---|
| K13 5G, 8GB+128GB | ₹17,999 |
| K13 5G, 8GB+256GB | ₹19,999 |
| A6s 5G, 4GB+128GB | ₹18,999 |
| A6s 5G, 6GB+128GB | ₹20,999 |
At launch, the K13’s 8GB+256GB configuration was ₹1,000 less than the A6s’s 6GB+128GB configuration, while listing more RAM and twice the storage. That comparison is historical, not a current value verdict. OPPO’s launch announcements also described time-limited offers: the A6s announcement mentioned a flat ₹1,000 cashback and financing offers, while the K13 announcement mentioned a sale-day instant discount and exchange bonus. Those launch offers should not be assumed to remain available. See the K13 launch announcement and A6s launch announcement.
No current retailer checkout prices or stock were verified. Before buying, compare live listings for the same RAM and storage configuration, and check the seller, warranty and any offer conditions.

Which OPPO A6s version are you comparing?
Model codes matter because the A6s name is used for more than one regional model. This article compares the India CPH2889 against the India K13 CPH2729. OPPO’s Global A6s 5G specification page identifies model CPH2789, a different configuration. Do not assume specifications for one A6s region apply to another. Confirm the model code on the product listing or box and match it to the relevant regional OPPO page.
