The upcoming Realme phone is expected to be a concept phone and not a commercial unit, which means it may not be available to buy. According to the poster, the 15,000mAh battery phone will deliver up to 50 hours of video playback on a full charge. It is also claimed to offer over 5 days of backup on a single charge.
Previously, Realme had unveiled a 10,000mAh concept phone back in May with an ultra-high silicon-content anode battery. It features a 10 percent silicon ratio, which is said to be the highest for any smartphone. The 10,000mAh Realme concept phone packs a ‘Mini Diamond’ architecture that offers an energy density of 887Wh/L. It supports 320W fast wired charging. The phone is just 8.5mm thick like a regular phone and weighs just over 200 grams.
Realme introduced the 320W SuperSonic Charge technology in August last year. It is claimed to charge the device from 0 to 100% in just 4 minutes and 30 seconds. According to Realme, the charging technology can charge 26% of battery in just a minute while a two-minute charge can provide up to 50% of charge to the battery.
