OPPO F35 Pro Expected This Week: 10,000 mAh Battery, 80 W Charging, and More

Last updated: 2 September 2026  |  By Royal Star Team

OPPO is gearing up to drop what could be the most battery-obsessed smartphone of the year. The OPPO F35 Pro, expected to launch in India sometime this week — likely ahead of Flipkart's Big Billion Days sale — has been making waves thanks to one jaw-dropping number: a 10,000 mAh battery.

Before we dive in, a critical caveat: OPPO has not officially announced the F35 Pro yet. Everything below is drawn from credible leaks and tipster reports. We'll update this article the moment official specs drop. Never take pre-launch information as confirmed fact.

Expected Battery: 10,000 mAh with 80 W SUPERVOOC

If the rumours hold, the F35 Pro will house a 10,000 mAh dual-cell battery — that's larger than most tablets and nearly 50% bigger than what you'll find in competing phones at this price.

Pairing that monster cell with 80 W SUPERVOOC charging should mean a full top-up in about 70–80 minutes, which is reasonable given the sheer capacity. For perspective, the Vivo T5 5G (launched today) has a 7,050 mAh cell with only 44 W charging — the F35 Pro is tipped to beat it on both fronts.

If you're curious about how wattage claims translate to real-world charge times, our fast-charging wattage buying guide breaks it all down.

Expected Chipset: Snapdragon 4 Gen 5

The F35 Pro is tipped to run the Qualcomm Snapdragon 4 Gen 5, an efficiency-focused chip built on a 4 nm process. While it won't match the raw muscle of the Dimensity 7500 Turbo or Snapdragon 7s Gen 3, it's designed for exactly the kind of phone the F35 Pro appears to be — one that prioritises sustained performance and battery life over benchmark bragging rights.

For everyday tasks like WhatsApp, Instagram, UPI apps, and casual gaming, the Snapdragon 4 Gen 5 should be more than adequate. Hardcore gamers may want to look elsewhere.

Expected Display: 6.78-Inch 1.5K LTPS OLED at 120 Hz

Leaks point to a 6.78-inch 1.5K LTPS OLED display with a 120 Hz refresh rate. That's a solid panel for the price — LTPS (Low-Temperature Polycrystalline Silicon) is the display tech you'll find in most mid-range phones, offering good colour accuracy and power efficiency.

It won't have the adaptive refresh-rate intelligence of LTPO (which drops to 1 Hz to save power), but with a 10,000 mAh cell backing it, battery drain from the display is the least of your worries.

Expected Camera: 50 MP Dual Rear + 50 MP Selfie

Camera details are thinner, but tipsters suggest a 50 MP + 2 MP rear setup and a 50 MP front-facing camera. The 2 MP secondary lens is almost certainly a depth sensor — useful for portrait mode but not much else.

The focus here seems to be on the selfie camera. A 50 MP front shooter would put the F35 Pro ahead of most competitors in this bracket for video calls and social-media content. OPPO has historically done well with selfie processing, so this could be a strong suit.

Expected Build: IP66/68/69K in an 8.57 mm Frame

The F35 Pro is tipped to carry triple IP ratings — IP66, IP68, and IP69K. The IP69K rating, if confirmed, means the phone can withstand high-pressure, high-temperature water jets. It's the same rating used for industrial equipment, and only a handful of smartphones worldwide carry it.

Thickness is expected at 8.57 mm — not ultra-slim, but entirely reasonable for a phone packing 10,000 mAh. Weight hasn't leaked yet, but expect something north of 210 grams. If you're investing in a premium phone like this, a good screen protector is non-negotiable — here's our explainer on what 9H tempered glass hardness actually means.

Expected Price and Timing

Multiple sources peg the F35 Pro at ₹40,000–₹45,000 in India. The launch is widely expected before Flipkart's Big Billion Days sale, which historically kicks off in late September or early October. A pre-BBD launch would let OPPO ride the festive-season marketing wave.

No official sale date has been confirmed. Keep an eye on OPPO India's social channels for the formal announcement.

Should You Wait for the OPPO F35 Pro?

Wait if: Battery life is your absolute top priority and you're willing to spend ₹40K+ for a phone that could genuinely last three days on a single charge. The 80 W charging and triple IP ratings sweeten the deal.

Don't wait if: You need a phone today, you care more about gaming performance than battery endurance, or you're uncomfortable buying a phone based on leaked specs. The Vivo T5 5G is available right now with a proven 7,050 mAh cell and a stronger chipset.

FAQ

Q: Is the OPPO F35 Pro officially launched?
A: No. As of 2 September 2026, the F35 Pro has not been officially announced by OPPO India. All specifications mentioned in this article are based on pre-launch leaks and should be treated as unconfirmed.

Q: Where will the OPPO F35 Pro be available?
A: It's expected to launch on Flipkart, consistent with OPPO's recent India launches. Amazon and offline availability may follow later.

Q: How does a 10,000 mAh battery compare to other phones?
A: For reference, the iPhone 16 Pro Max has a 4,685 mAh battery, and the Samsung Galaxy S25 Ultra has 5,000 mAh. At 10,000 mAh, the F35 Pro would have roughly double the capacity of most flagship phones.

Q: Will OPPO F35 Pro support 5G?
A: Yes, the Snapdragon 4 Gen 5 supports 5G. Both Jio and Airtel 5G bands are expected to be covered.

Final Thoughts

The OPPO F35 Pro — if the leaks are accurate — is shaping up to be the ultimate battery phone for India. A 10,000 mAh cell with 80 W charging, wrapped in an IP69K-rated body with a 1.5K OLED display, sounds like a phone designed for people who treat a dead battery as a personal emergency.

We'll reserve final judgement until OPPO makes it official, but the early signs are promising. In the meantime, if you're exploring what's new in the Indian phone market, check out our coverage of the Samsung Galaxy S26 FE launch and the latest on India's USB-C mandate for chargers and cables.
