OPPO is gearing up to refresh its rugged F-series in India with the F33 and F33 Pro in the third week of April, according to exclusive information received by 91mobiles from industry sources. Building on last year’s F31 lineup, these mid-rangers could double down on battery life and durability, which are key selling points of the mid-range price bracket.
The current OPPO F31 series launched in September 2025 in India, comprising the F31 5G, F31 Pro 5G, and F31 Pro+ 5G. It was priced from Rs 22,999 for the OPPO F31 5G 8GB +128GB model going up to Rs 32,999 for the OPPO F31 Pro+ 8GB + 256GB variant. For that series, OPPO packed in 7,000mAh batteries with 80W SUPERVOOC charging, IP66/68/69 water and dust resistance, and MIL-STD-810H military-grade build quality. In practice, that meant the phones could last longer between charges and handle a bit more wear and tear than most rivals. A 50MP OIS main camera, 32MP selfie shooter, MediaTek Dimensity chip, and vibrant AMOLED displays rounded out the appeal, making them easy picks for users who prefer tough and long-lasting phones.
There’s no word yet on what exactly changes with the OPPO F33 and F33 Pro. But unless OPPO changes direction, the F33 duo should follow suit, while tweaking performance and cameras for yearly upgrades.
While full details remain under wraps, we can speculate the F33 series to land in the Rs 25,000 – Rs 35,000 segment, based on the price rise trend across markets and the positioning of the OPPO F31 phones. For that price, the standard F33 might replicate the F31’s core strengths including the battery and durability while the F33 Pro could step up with more RAM, a stronger chipset and camera setup.
If the phones do launch in that segment, they will go up against the likes of the Motorola Edge 70, Redmi Note 15 Pro and Nothing Phone (4a). Motorola keeps things clean and close to stock Android, Redmi usually focuses on getting the most hardware for the price, and Nothing leans into design and software identity. OPPO, with the F-series so far, has been more practical with battery life and durability first, and everything else around that.
If you care more about a phone that lasts longer on a charge and can take a bit of rough use, the F-series has usually been a safe pick in this segment. We should know more about the performance, camera quality, etc once we get our hands on the devices. If the F33 series continues its tradition of robust battery life and durability, it will likely appeal to users who prioritize these aspects over camera tech or raw processing power.
