It typically takes about 1 to 4 hours to fully charge a lithium-ion battery, depending on the device and charger used. Most smartphones fully charge in approximately 1.5 to 2.5 hours with a standard charger. In contrast, larger devices like laptops can take about 2 to 4 hours for a complete charge.
[pdf] Researchers from Dalhousie University used the Canadian Light Source (CLS) at the University of Saskatchewan to analyze a new type of lithium-ion battery material – called a single-crystal electrode – that’s been charging and discharging non-stop in a Halifax lab for more than six years.
