Frequently charging a battery under high voltage will quicken its aging.When a battery-charged laptop is externally connected to additional USB or Thunderbolt devices, the battery power will also discharge faster. For example, running computation-heavy programs, such as graphics software, gaming software, and video playing, consumes more power than running general word processing software. The battery’s discharge rate depends on the laptop’s or tablet’s software operations and power management settings.High/low operating temperatures and abnormal operations may result in 70% or more rapid decrease of the battery’s life cycle within a short time. Battery life decline varies with the system design, model, system power consumption, program and operating software consumption, and power management settings.Afterwards the battery capacity will drop to 80% of its initial capacity. Under normal usage conditions and in ambient temperatures (25℃), the Li-ion battery is expected to discharge and recharge normally for 300 cycles (or about one year). The life of a Li-ion battery is approximately between 300-500 cycles.Due to the chemical properties of Lithium ions, battery capacity decreases gradually with use over time.More ASUS Battery Information Center Last Update : 7
