OPPO's about to shake up India's mid-range phone market in a big way. The F35 and F35 Pro are launching in October 2026, and the standout spec is absolutely wild: a 10,000mAh battery crammed into a device thinner than most flagship phones. To put that in perspective, this capacity is double what was standard just 18 months ago. We're talking about a phone that could realistically deliver two to three days of use on a single charge for moderate users, while the iPhone 18 Pro Max manages 45 hours of video playback. The F35 Pro's massive cell routinely hits 60+ hours in the same test.
What makes this achievement even more impressive is how OPPO's engineers managed the slim profile. At 8.57mm thick, the F35 Pro shouldn't exist on paper. The company's clearly invested heavily in cell density and internal optimization to pull off this balancing act. Pairing that huge battery with 80W fast charging means you're looking at roughly 30 minutes to 50% and a full charge in around 70-80 minutes. That's not the quickest charging out there, but it's totally reasonable for a battery this enormous. The real question is whether thermal performance holds up during extended use, which we'll know once real-world reviews hit.
Design-wise, OPPO's gone bold with variety. The F35 Pro comes in brown, orange, and light blue, while the standard F35 offers pink, silver, and purple. More interesting than the color lineup are the decorative finishes, with floral patterns on one variant and wave-like textures on another. It's a refreshing departure from the endless sea of matte-glass rectangles you see everywhere.
Under the hood, you're getting a Snapdragon 4 Gen 5 processor paired with UFS 3.1 storage, which is a solid choice for the price bracket. The dual camera setup features a 50MP main sensor and 50MP selfie, so you'll get decent shots in good lighting, though this isn't a phone you'd buy primarily for photography. There's also a 2MP depth sensor that's essentially just there.
The F35 series lands in India first this October, with other markets following later. In a market where Xiaomi, Realme, and Samsung have been trading blows over battery capacity and value, OPPO's throwing down a serious challenge. The battery war in the mid-range is heating up, and OPPO's betting that doubling the capacity will be enough to win over buyers looking for real battery endurance without the flagship price tag.
