It is all thanks to silicon-carbon battery technology; only this company has reached a 7000mAh battery. But now, Realme is using this silicon-carbon battery technology to create an unbelievable concept. They are unveiling the first 10,000mAh and then the 15000mAh. While the company has not directly listed the number, if we look closely, users will see there are characters looking into a phone, and on the phone itself, there is a 15000mAh written on the back panel.
If we think about it more deeply, this would not be entirely new. Realme has already put out a concept phone with a 10000mAh battery, showcased earlier this year. Now that the 15,000mAh figure has entered the fray, the company is looking to push things further. In the official teaser, Realme has claimed that it can provide 50 hours of non-stop streaming, which is, of course, a massive number for a smartphone. They have also announced the date, which is 27 August, which is today. So, see the latest updates that Realme will offer to use on social media platforms.
Realme is also pushing its limits in charging technology; the company already has a 320W supersonic charge, which it previously claimed could power a 4,420 mAh battery from 0% to 100% in about just four minutes. A charging technology like this would be needed to recharge a battery as large as 15,000mAh in a short time.
