At Realme’s 828 Fan Festival in China, two jaw-dropping concept phones were unveiled. One of them has a large 15,000mAh battery inside, and the other carries a built-in cooling fan and a thermoelectric heat dissipation system. Realme calls it the world’s first “AC” smartphone. Here are some details on both of them.
Realme 15000mAh
The one with a minimal horizontal camera bar is a 15,000mAh phone that apparently uses a 100% Silicon Anode battery design. It’s almost four times the size of an average Si/C cell on a smartphone. From what the company advertises, the battery gets a whopping 1,200 Wh/L energy density.
This battery will last nearly a week or five days minimum if you are a power user. That claim is subjective, though, as Realme didn’t share the parameters for battery testing. Be that as it may, we still can’t fathom a 15000mAh charge capacity on an average-looking phone such as this.
This prototype model is only 8.89mm thick. But that’s not the surprising part. The power pack inside the phone only measures 6.48mm in depth, despite the ridiculous 15,000mAh energy capacity. Realme had to rearrange some hardware components and optimize the battery packaging process to achieve this thickness.
None of its specs were announced at the debut, but the Realme 15,000mAh concept has been reported with a Dimensity 7300mAh SoC and 12GB RAM. The display might be 6.7” in size.
Realme Chill Fan Phone
The Realme Chill Fan prototype, as implied by the name, is entirely focused on thermal management. It has a more traditional look and a 10,000mAh battery. This concept uses three types of heat dissipation methods, which keep the temperatures down by up to 6°C.
It has one of the largest vapor cooling chambers on a phone at 7,700mm2. This takes heat away from the SoC and out of the rear cover. Realme’s IseSense Ultra rear shield tends to shift colors in real time as the temperature goes down.
There’s also a spinning fan here for active cooling, which is probably the most effective method of heat control on this prototype. Then, we have a thermoelectric cooling solution on the device. It’s basically a mini-sized AC that uses the Peltier effect for thermal control.
The chill phone concept looks identical to one of the Realme GT 7 devices, except for a perforated grille on the side for an active cooling fan. These are interesting prototypes and show how far ahead Realme’s R&D team is with thermal and battery innovation. Sadly, neither of these phones will ever appear in the consumer market, at least not until Realme says otherwise.
