Realme UltraDart Fast Charging is official: initials long to identify something that instead points to shorten the charging time of the smartphone battery. Realme thus becomes part of the group of companies that are intensifying their investments to make further progress forward in the technology for fast charging.
The news is not surprising since it had been announced and arrives a few hours after Oppo's formalization of its similar solution for wired charging at 125W – even if Realme is independent of Oppo, from which it was originally born as sub-brand, it is likely that you will continue to share resources and technologies.
There is still no mention of Realme smartphones that will use 125W charging technology but the benefits are starting to be quantified: the company refers to the possibility of restoring 33% of the charge of a 4,000 mAh battery in 3 minutes.
And to reduce the disadvantages deriving from a fast charging carried over the 100W wall, Realme uses the concept of a charging technique that takes into account three elements: a dynamic and gradual management of the voltage to maximize the power charge and reduce the production of heat.
According to the company, thanks to the system developed – which also includes the use of a multilayer graphite sheet – the temperature during the refilling process never exceeds 40 degrees centigrade. Realme's UltraDart Fast Charging technology is also backwards compatible with the VOOC, Dart, Warp, SuperVOOC, SuperVOOC 2.0 and SuperDart charging protocols, and can be used both for charging smartphones and notebook batteries. For something more concrete – that is, for the first devices that will actually use it – you have to wait.
Meanwhile, following Oppo's example, Realme also presented new compact chargers that support 50W and 65W charging.
