Where the phones differ in everyday buying priorities
Battery capacity and charging
OPPO lists a 7,000mAh typical battery and 80W SUPERVOOC charging for the K13. Samsung lists a 5,000mAh typical battery and charging up to 25W for the A35, and says its 25W wall charger is sold separately. These figures give the K13 the stronger published capacity and charging specifications, but they do not establish how long either phone lasts in real use or how quickly it charges under particular conditions.

Display size and format
Both phones have FHD+ AMOLED-class displays with refresh rates up to 120Hz. OPPO lists a 6.67-inch panel and Samsung a 6.6-inch-class panel, making the K13 slightly larger by stated diagonal. Those specifications alone do not establish which screen looks better.
Camera options
The A35 has three listed rear modules: a 50MP main camera with OIS, an 8MP ultrawide and a 5MP macro camera. The K13 lists a 50MP wide camera and a 2MP monochrome camera. If an ultrawide or macro option matters to you, Samsung’s listed configuration is more versatile; if camera quality is the deciding factor, compare sample photos or independent testing. Megapixel counts and lens counts are not quality tests.

Storage, connectivity and protection
Both are listed in 8GB/128GB and 8GB/256GB configurations. Samsung’s 256GB product listing documents microSD expansion up to 1TB, but the hybrid SIM slot means buyers should check the precise slot arrangement and regional SKU. Samsung also lists NFC and IP67 on its product information; OPPO lists Wi-Fi 6 and specifies model CPH2729. Check the exact variant’s carrier-band support and whether you need NFC or a particular protection rating.
India price difference: compare dates and storage tiers
There is no single dependable price difference in the supplied dated listings: reported prices disagree, and the figures do not all describe the same storage variant or offer conditions.
