With one charge, the Realme concept phone can provide up to 18 hours of video recording, up to 30 hours of gaming, up to five days of normal usage, and up to three months of standby time in flight mode.

While specifications remain under wraps, the handset was spotted on social media running on Android 15-based Realme UI 6.0. It is allegedly powered by a MediaTek Dimensity 7300 processor, paired with 12GB of RAM and 256GB of storage. The RAM is said to be further expandable by another 12GB virtually.

The handset was shown bearing the model number PKP110. The Realme concept phone's About page also suggests the inclusion of a 6.7-inch display. Teaser images reveal a dual-rear camera setup at the back of the phone. It is shown in a silver colourway, with the 15,000mAh branding on the back panel.

Meanwhile, the Realme Chill phone is named as such due to the presence of built-in cooling fans. It is said to have a “built-in AC inside”. The teaser video indicates a vent grille on the left frame of the phone through which air may escape. As per the Realme Vice President, the cooling system helps cool down the handset by up to 6 degrees Celsius.

In terms of design, it sports a camera unit that is identical to the one on the Realme GT 7T. The handset is shown in a blue colourway, which is slightly more saturated than the IcySense Blue shade of the aforementioned phone.

Notably, both handsets are concepts, meant to showcase Realme's advancements in R&D. There is no word on their mass-market availability as of now.
