The realme C83 5G is the more clearly equipped choice if you need 5G, a higher advertised refresh rate, or faster specified charging. The OPPO A6x compared here is the India-market A6x 4G (CPH2819), not OPPO’s separate A6x 5G model. Both have HD+ LCD screens and list 13MP rear and 5MP front cameras, while a reliable current price gap cannot be established from the available comparison listing.
First, identify the OPPO A6x variant
“OPPO A6x” can refer to different models. OPPO India’s specification page for model CPH2819 lists a Snapdragon 685 and does not specify 5G; OPPO also publishes a separate A6x 5G. This comparison is about the OPPO A6x 4G (CPH2819) and the realme C83 5G. Check the model name and network support on the exact listing before buying. OPPO A6x 4G specifications

Specifications are from the manufacturers’ India pages: OPPO A6x and realme C83 5G. They describe listed hardware and features, not comparative test results.
Network and performance: 5G is the clearest difference
The realme C83 5G explicitly lists 5G NR support and uses a MediaTek Dimensity 6300. OPPO’s A6x CPH2819 page lists the Snapdragon 685 and does not specify 5G. Choose the C83 if 5G connectivity is a requirement; do not treat the separate A6x 5G as the model being compared here.

- Precise cutouts are designed for easy access to all ports, buttons and camera. The buttons are soft, responsive and easy to press, and are easy to install and remove.
The chipset names alone do not establish which phone feels faster in everyday use. The cited specification pages do not provide a controlled head-to-head performance test, so there is no substantiated speed winner here.
Display: realme advertises a higher refresh rate
Both phones have LCD panels with the same listed HD+ resolution of 1570 × 720. The C83 advertises a maximum refresh rate of 144Hz, compared with up to 120Hz on the A6x. Those are maximum specifications, not a guarantee that every app or situation will run at the maximum rate.
OPPO lists higher brightness figures: 800 nits typical and 1125 nits HBM, against realme’s 700 nits typical and 900 nits HBM. These manufacturer figures use the stated typical and high-brightness modes; they do not establish which screen is easier to read in every real-world condition.

Battery and charging: larger listed capacity on the C83
realme lists a 7000mAh typical-capacity battery and up to 15W charging for the C83. OPPO lists 6500mAh typical capacity (6335mAh rated) for the A6x and says fast charging is unsupported. On the listed specifications, the C83 has both the larger nominal battery and the defined fast-charging capability.
Capacity and charging ratings do not prove which handset lasts longer between charges in actual use. OPPO describes the A6x battery as “5-Year Long-Lasting,” a manufacturer longevity claim. realme says its C83 battery is expected to remain above 80% capacity after six years of continuous use under normal-temperature conditions, based on realme lab data and an assumption of one charge per day. That is realme’s claim, not an independent test result. OPPO A6x product page · realme C83 product page
Cameras: similar headline resolutions, no quality verdict
Both manufacturers list a 13MP f/2.2 autofocus rear camera and a 5MP f/2.2 front camera. OPPO also lists a QVGA monochrome secondary camera. Matching headline megapixel counts do not establish matching photo quality, and the available specifications do not include a controlled camera comparison.

Memory, storage, and size
OPPO’s cited A6x page lists one configuration, 4GB RAM with 64GB storage, and storage card support. realme lists 4GB or 6GB RAM and 64GB or 128GB storage, up to 6GB + 128GB. The C83 therefore has more listed built-in storage and memory configurations; confirm the exact SKU and card support on the retail listing, since the cited C83 specification extract does not state card support.
The phones are close in listed dimensions and weight: the OPPO is about 210g and the realme about 212g. That small difference on paper does not by itself establish which feels more comfortable in hand.

A 91mobiles comparison page displayed Amazon price references of ₹18,999 for the OPPO A6x and ₹17,499 for the realme C83 5G. The figures imply a ₹1,500 difference in that captured listing, but they are not verified live offers, and the OPPO variant mapping is unclear. They should not be treated as current prices or as a dependable price comparison. 91mobiles comparison listing

For a useful current comparison, check India retailer listings on the same day and match the exact network model, RAM, and storage. A 4GB + 64GB phone and a 6GB + 128GB phone are not equivalent configurations, even if the product names look similar.
Which phone should you choose?
- Choose the realme C83 5G if you need 5G, want the higher advertised 144Hz refresh rate, or prefer its listed 7000mAh battery and up to 15W charging.
- Consider the OPPO A6x 4G if 4G meets your needs and its exact current price or other requirements make it the better fit. Its manufacturer page lists higher typical and HBM brightness figures, but does not specify fast charging.
- Compare exact configurations and current prices before deciding: the available comparison-page price references do not establish today’s price gap, and the listed storage options differ.
Neither specification sheet establishes a winner for measured speed, real-world battery life, or camera quality.
