Which display is better on paper?
Both phones have an HD+ LCD with the same listed 1570 × 720 resolution. The realme C83 5G has the higher maximum refresh-rate specification, 144Hz versus 120Hz for the OPPO A6 5G. That gives the C83 an advantage on this particular spec, but the figures alone do not establish how smooth either phone feels in everyday use or which screen looks better overall.

OPPO lists higher brightness figures: 900 nits typical and 1125 nits HBM, compared with realme’s 700 nits typical and 900 nits HBM. These are manufacturer specifications, not a matched independent display test. Both screens are LCD and HD+; claims that the India A6 has an AMOLED or FHD+ screen conflict with OPPO’s official specifications.
Performance, memory and storage
Both official India specification pages name the MediaTek Dimensity 6300. OPPO lists an eight-core processor; realme specifies an eight-core, 6nm chipset. The available specifications do not establish which phone is faster in real-world use, so it would be misleading to declare a performance winner without matched testing.
The OPPO A6 5G’s listed configurations start at 128GB and extend to 256GB. The realme C83 5G is listed with 64GB or 128GB storage, depending on variant, and realme advertises up to 6GB of dynamic RAM. Check the exact C83 storage and RAM configuration at checkout rather than assuming every seller stocks the same option.

Camera specifications are not image-quality results
OPPO lists a 50MP main camera with a 2MP monochrome camera and an 8MP front camera. realme lists a 13MP rear camera and a 5MP front camera. Those numbers describe resolution and listed camera hardware; they do not demonstrate which phone takes better photos or video. No matched camera samples or independent comparison results are established here.
Battery capacity and charging
Both manufacturers state a 7000mAh typical battery capacity. OPPO additionally lists 6830mAh rated capacity. These capacity figures do not guarantee a particular runtime: usage, settings and network conditions matter, and no independent matched battery-runtime result is established here.
The clearer specification difference is charging: OPPO states up to 45W SUPERVOOC, while realme states up to 15W fast charging. OPPO also lists compatibility with specified lower-wattage SUPERVOOC, PPS and PD charging. Confirm which charger, if any, is included with the precise sales package before relying on an accessory being supplied.

Both brands publish battery-longevity projections, but they are not comparable independent tests. OPPO says its lab simulation estimates more than 80% capacity retention after five years, based on daily behavior with a full charge and discharge about once every 1.1 days. realme describes a theoretical lab-based calculation of above 80% capacity after six years under normal-temperature conditions with once-daily charging. Treat each as a manufacturer claim, not a runtime result or a guarantee for an individual phone.
Water and dust resistance claims
OPPO publishes IP66/IP68/IP69 ratings for the A6 5G, with controlled-lab conditions and limitations. OPPO warns that resistance can decline with wear and says liquid damage is not covered by warranty. The official realme C83 specification page reviewed does not state an IP rating; that does not establish that the phone has no resistance, only that a rating was not verified from that page.
What the displayed price difference means
A 91mobiles comparison page accessed in 2026 displayed ₹23,999 for the OPPO A6 and ₹19,999 for the realme C83 5G—a displayed difference of ₹4,000. This is a third-party page snapshot, not an official price or a guaranteed current offer, and the exact configurations behind the displayed prices are not established here. Check current listings for the same storage variant before comparing value. The realme Store listing surfaced a 4GB+64GB variant, but no usable price was available from the retrieved listing; an official OPPO price was not verified.

Which one fits your priorities?
- Consider the realme C83 5G if the higher listed refresh rate matters most and a 64GB or 128GB storage option suits your needs.
- Consider the OPPO A6 5G if you prefer its higher maximum charging specification, higher listed camera resolutions, 128GB-or-more storage configurations, or its published IP ratings.
- Compare the exact live prices for the same storage configuration; the displayed ₹4,000 gap is only a dated third-party snapshot.
- Do not choose based on assumed speed, camera quality or battery life from these specifications alone. The shared chipset and typical battery rating do not substitute for matched real-world tests.
