Realme reveals more details about 15,000mAh phone and new Chill Fan Phone

Realme decided to reveal a few more details about two smartphones at the 828 Fan Festival 2025 event. One of them is the famous 15,000-battery giant (we still have no idea what to call it properly), and the other is the Chill Fan Phone.

Realme 15,000 mAh Battery Phone

• The manufacturer claims that it was able to implement a 100% silicon anode in this device for the first time in the world.
• The energy density of the battery is a record 1200 Wh/l
• The battery is laminated and has a thickness of 6.48 mm, and the entire phone is 8.89 mm

This capacity, according to the manufacturer, should provide up to ~18.5 hours of video recording, ~30 hours of gaming, ~50 hours of video, up to 5.18 days of normal use, or up to 3 months of standby time with the airplane mode enabled.

According to preliminary rumours, the device has a 6.7″ OLED screen, MediaTek Dimensity 7300 chip, 12GB RAM + 256GB flash memory, and supports 80W SuperVOOC charging.

It seems that this is just a concept - mass production is not planned due to the danger of deformation of the all-silicon anode, which can cause a short circuit and release all those 15,000 mAh in a few seconds.

Realme Chill Fan Phone is an "AC smartphone"

The smartphone has advanced cooling - an evaporation chamber with an area of 7700 mm² + a fan + a thermoelectric cooler (TEC). A temperature drop of 60°C is claimed, even with heavy games. The back panel of the IceSense Ultra smartphone changes colour from white to blue when active cooling is in operation. Mass production has not been confirmed.
