realme said that it has used new battery material, high energy density and packing the battery into a slimmer body of the phone.
- Step 1: The world’s first all-silicon content anode battery with 25% silicon content
- Step 2: The world’s highest battery energy density of 1200Wh/L
- Step 3: Package the phone slimmer making the main board to world-record 23.4mm and applied advanced lamination to the battery making the battery of the phone just 6.48mm and the phone 8.89mm
The company says that the 15000mAh battery phone will offer up to 18.45 hours of video shooting or 30 hours of gaming, or up to 50 hours of video playback on a single charge. A single charge will offer up to 5.18 days of use and up to 3 months of standby in airplane mode, adds the company.
A 6.7-inch OLED screen, MediaTek Dimensity 7300 SoC, 12GB RAM, and 256GB of straoge have also been confirmed for the phone, which is similar to the realme 10,000mAh concept phone from earlier this year. The teaser revealed 80W SuperVOOC charging for the phone.
realme Chill fan phone
realme also introduced the Chill fan phone, calling it the world’s first “AC” phone!
In addition to the 7700mm² VC cooling and fan heat dissipation, this uses TEC: Thermoelectric cooler. realme says that it has used a tiny semiconductor that can reduce the core temperature by 6º C, which is 2 to 3 times better than the cooling performance of the traditional VCs.
The IceSense Ultra phone back gradients from white to Blue when the temperature of the phone goes down to 38º from 45º C. realme says that it has tested this in a popular anime strategy game in full FPS, and it achieved up to 6.2º C reduction in the temperature.
We still don’t know when the Chill fan phone will be mass-produced. Even though the 15,000mAh battery phone might not be a reality anytime soon, the 10,000mAh battery is expected to arrive in the market as early as 2026, based on earlier reports.
