A Bold Leap in Smartphone Battery Innovation
Realme has captured the spotlight with its 15000 mAh battery concept phone, a revolutionary prototype showcased at the Realme 828 Fan Festival on August 27, 2025, in China. This concept device, alongside the Realme Chill Fan Phone, demonstrates Realme’s commitment to addressing key user pain points like battery life and overheating. With an unprecedented 15000 mAh battery, a sleek design, and advanced technology, this phone promises up to five days of usage on a single charge. Below, we explore the Realme 15000 mAh battery phone’s name, price, specifications, features, and why it’s a game-changer, despite remaining a concept for now.
Launch Date and Status in India
The Realme 15000 mAh battery concept phone was unveiled on August 27, 2025, during the Realme 828 Fan Festival in China, with the event likely starting around 10:00 AM CST (11:30 AM IST). Realme has not confirmed a commercial launch, and the device remains a concept prototype, meaning it is not available for purchase in India or globally as of August 29, 2025. However, Realme hinted that a 10,000 mAh battery phone could debut commercially by 2026, suggesting future iterations may incorporate this technology. In India, the concept has sparked significant interest due to the country’s demand for high-capacity batteries amid frequent power cuts and long commutes.
Price in India
As a concept phone, the Realme 15000 mAh battery phone has no official price or commercial availability. Industry speculation suggests that if commercialized, it could be priced between ₹30,000 and ₹40,000 (ex-showroom) in India, factoring in the advanced 100% silicon anode battery and premium features. On-road prices could range from ₹35,000 to ₹45,000, depending on taxes and insurance. For context, Realme’s earlier 10,000 mAh concept phone was estimated at a similar price point, and the Realme GT 7 with a 7,000 mAh battery retails around ₹35,000 in India.
Phone Name
The official name of the Realme 15000 mAh battery concept phone has not been finalized, as it is referred to simply as the “Realme 15000 mAh” or “15000 mAh battery concept phone” in promotional materials. Social media posts suggest the model number PKP110, but Realme has not confirmed a market-ready name like “GT” or “Narzo” for this prototype.
Specifications
The Realme 15000 mAh concept phone is powered by a 100% silicon anode battery with an industry-leading 1,200 Wh/L energy density, enabling a 15000 mAh capacity in a slim 8.89 mm thick chassis. It features a MediaTek Dimensity 7300 processor, 12GB RAM, and a 6.7-inch OLED display, balancing performance and efficiency. The device supports 80W SuperVOOC charging and can act as a power bank via reverse charging.
Key Specifications:
- Battery: 15000 mAh, 100% silicon anode, 1,200 Wh/L energy density
- Processor: MediaTek Dimensity 7300
- RAM/Storage: 12GB RAM (expandable by 12GB virtually), 256GB storage
- Display: 6.7-inch OLED, FHD+ (rumored)
- Charging: 80W SuperVOOC, reverse wired charging
- OS: Realme UI 6.0 based on Android 15
- Thickness: 8.89 mm (battery: 6.48 mm)
- Weight: ~200-220 grams (estimated)
- Camera: Dual rear (48MP main, specs unconfirmed), 12MP front (rumored)
Mileage (Battery Life)
The 15000 mAh battery delivers exceptional endurance:
- Up to 5-6 days of normal usage
- 50 hours of video playback
- 18-18.75 hours of continuous video recording
- 30 hours of gaming
- 3 months of standby in airplane mode
Real-world estimates suggest 4-5 days for mixed usage (calls, browsing, gaming), making it ideal for heavy users and Indian consumers facing unreliable power supply. The 100% silicon anode battery achieves this with a 1,200 Wh/L energy density, four times that of conventional silicon-carbon batteries, though it poses safety and degradation challenges.
Features
The Realme 15000 mAh concept phone is packed with cutting-edge features:

- Performance: MediaTek Dimensity 7300, 12GB RAM for smooth multitasking
- Display: 6.7-inch OLED with vibrant colors
- Charging: 80W SuperVOOC for faster top-ups, reverse charging for devices like drones or wearables
- Design: Semi-transparent “Newborn” aesthetic, showcasing the battery and components
- Software: Realme UI 6.0 based on Android 15, with AI enhancements
- Camera: Dual rear camera system (48MP primary, specs unconfirmed), 12MP front camera
Design
The Realme 15000 mAh concept phone features a sleek, futuristic design despite its massive battery. At 8.89 mm thick and weighing just over 200 grams, it rivals flagship phones like the Samsung Galaxy S25 Ultra (8.2 mm, 5,000 mAh). The semi-transparent grey shell exposes the battery and components, aligning with Realme’s youth-focused, innovative branding. The 6.7-inch OLED display has slim bezels, and the rear sports a dual camera system with a modern layout.
Review
As a concept phone, the Realme 15000 mAh battery phone has not been tested hands-on, but early impressions from the 828 Fan Festival and leaks are overwhelmingly positive. Tech enthusiasts praise its unprecedented battery life, with claims of 50 hours of video playback and 5 days of usage addressing battery anxiety, especially for Indian gamers and content creators. The slim 8.89 mm profile defies expectations for a 15000 mAh battery, and the semi-transparent design adds a futuristic appeal. However, the 100% silicon anode battery raises concerns about long-term degradation and safety, making mass production unlikely soon. The MediaTek Dimensity 7300 ensures decent performance, but it’s not as powerful as flagship chips like the Snapdragon 8 Elite. If commercialized, it could redefine smartphone endurance, but for now, it’s a bold R&D showcase.
Comparison with Competitors
The Realme 15000 mAh concept phone stands out in the high-capacity battery segment:
- Vs. Realme GT 7 (7,000 mAh): Double the battery capacity, but GT 7 is commercially available at ~₹35,000.
- Vs. Honor 90 (8,000 mAh): Larger battery and slimmer design, but Honor’s phone is mass-produced.
- Vs. Oukitel Rugged Phones (22,000 mAh): Outperforms in capacity but avoids bulky rugged design.
- Advantages: Unmatched battery life, slim form factor, reverse charging
- Drawbacks: Concept-only, potential safety risks with silicon battery
Booking and Availability
The Realme 15000 mAh battery concept phone is not open for booking as it remains a prototype with no confirmed commercial release. Realme has stated it is a showcase of R&D capabilities, with no immediate plans for mass production due to safety concerns with the 100% silicon anode battery. However, a 10,000 mAh version is reportedly ready for production and could launch in India by 2026. For updates, check Realme India’s official website or authorized retailers like Flipkart and Amazon.
Final Verdict
The Realme 15000 mAh battery concept phone, unveiled on August 27, 2025, is a revolutionary prototype with a 15000 mAh battery, 158 km range equivalent, and a sleek 8.89 mm design. Offering up to 5 days of usage, 80W SuperVOOC charging, and a semi-transparent aesthetic, it addresses battery life concerns for Indian users. While not commercially available and lacking an official name or price, its ₹30,000-₹40,000 estimated cost (if launched) makes it a potential game-changer. With Realme’s focus on innovation, the 15000 mAh concept phone sets a new benchmark for smartphone endurance in 2025, even as a prototype.
