Charging speeds for mobile phones have hit a new milestone: A phone can be juiced from zero to 100 per cent in 25 minutes. The breakthrough, achieved by a slate of new smartphones from Chinese makers, places their charging speeds well ahead of the offerings of big boys such...
Released in July, it follows other recent devices that also come with proprietary 100W fast chargers, like the Oppo Find X6, Honor Magic4 Pro and the OnePlus 11.
OnePlus, which shares the same supply chain and manufacturing facilities as Oppo, also uses similar software for regulating electrical current flow when the battery is almost full to prevent overcharging and overheating. During charging, lithium ions are shuttled between two layers of electrodes – typically graphite and metal oxides – inside a battery, creating a flow of electrons that powers a device.
Overcharging typically happens after the 80 per cent charged mark if the flow of current is not regulated well. “Battery management software today can prevent too much current from passing through the battery,” he said. The Oppo Reno10 Pro+ and the latest 100W-charging phones by Honor also stop charging once the phone’s battery is full, such as during overnight charging.
