Oppo has officially expanded its popular F-series in India with the launch of the new Oppo F31 lineup on September 15, 2025. The series includes three models: Oppo F31, Oppo F31 Pro, and Oppo F31 Pro+. Marketed as the “Durable Champion,” the lineup combines a rugged design with a massive 7,000 mAh battery, fast charging, and advanced durability features.
With rising competition in the mid-range smartphone market, Oppo is positioning the F31 series as a reliable daily companion for users who value battery endurance, water resistance, and long-lasting performance. Ahead of the launch, let’s take a closer look at everything we know so far about Oppo’s upcoming F-series.

Durability Takes the Spotlight
The standout feature of the F31 series is its durability and ruggedness, something not usually highlighted in this price segment. All three models will come with a 360 Armour Body that offers multi-layer shock absorption, making them more resistant to accidental drops and impacts.
Oppo has also confirmed IP66, IP68, and IP69 ratings across the lineup. This means the phones can withstand dust, heavy water splashes, and even more severe conditions. In addition, Oppo claims the devices can perform smoothly even in high outdoor temperatures of up to 43°C, making them suitable for Indian weather conditions.
This durability focus positions the F31 series as a strong option for people who often work or travel outdoors and need a phone that can survive tougher environments.
Massive 7,000 mAh Battery with 80W Fast Charging
Battery life is another area where Oppo is pushing the limits. Each phone in the F31 series will feature a 7,000 mAh battery, one of the largest in this category.
Charging won’t be an issue either, thanks to 80W SuperVOOC fast charging, which can power the phone from 0 to 58% in just 30 minutes. A full charge reportedly takes just over an hour. Oppo has also added reverse wired charging, allowing users to power up smaller devices like earphones directly from the phone.
For heavy smartphone users, content creators, or frequent travellers, this combination of a huge battery and fast charging could be a major selling point.
Cooling and Heat Management
Big batteries and powerful processors usually mean more heat, but Oppo has equipped the F31 series with advanced cooling technology. The base model will have a 4,300 mm² vapour chamber, while the Pro and Pro+ models will use larger 4,363 mm² cooling systems with improved graphite layers.
This ensures better heat dissipation during intensive tasks like gaming, video recording, or long navigation sessions. It also ties into Oppo’s durability promise, as the phones are designed to remain stable even in high-temperature environments.
Oppo F31: The Standard Model
The Oppo F31 is expected to serve as the entry-level option in the lineup. According to leaks:
- Processor: MediaTek Dimensity 6300
- Display: 6.57-inch AMOLED panel with 120 Hz refresh rate
- Cameras: 50 MP main camera, two 2 MP portrait sensors, and a 16 MP selfie shooter
- RAM & Storage: Likely 8 GB RAM with up to 128 GB storage
- Cooling: Vapour chamber cooling system
With these specifications, the F31 should deliver solid mid-range performance while keeping costs competitive.
Oppo F31 Pro: Balanced Power
The Oppo F31 Pro will be a step up, offering better performance and improved camera features. Highlights include:
- Processor: MediaTek Dimensity 7300-Energy
- RAM & Storage: Up to 24 GB combined (including virtual RAM), with higher storage options
- Display: Similar AMOLED display with 120 Hz refresh rate
- Cameras: 50 MP main camera with OIS and a 32 MP front camera

This model is aimed at users who want more than just durability — offering smoother multitasking, gaming, and photography.
Oppo F31 Pro+: The Flagship of the Series
At the top end, the Oppo F31 Pro+ will feature premium specs while retaining the durability focus. Expected features include:
- Processor: Qualcomm Snapdragon 7 Gen 3
- Display: Larger 6.79-inch AMOLED panel with high refresh rate
- Cameras: 50 MP main camera with OIS, possibly additional advanced sensors, and a 32 MP selfie camera
- RAM & Storage: Likely up to 256 GB storage with higher RAM options
- Cooling: Advanced vapour chamber for stable long-term use
This model is expected to appeal to users who want flagship-level performance without paying flagship prices.
AI Features and Software
Oppo will also include its latest AI tools in the F31 lineup. Features like VoiceScribe, AI Call Assistant, and smart battery optimisation will be part of the package, improving productivity and everyday convenience.
The phones are expected to ship with ColorOS 15, based on Android 15, offering a fresh UI and long-term update support.
