Experts from "Apple" said that closing the applications that we do not use in our devices does not contribute to maintaining battery life for a longer period, contrary to the rumor, according to the British "Mirror" website.
Experts added that closing these applications consumes the device’s long-term life, as these applications are not in an active state that drains the battery.
Usually, the recently used applications are only ready, to help move between applications easily and do more than one task at the same time.
Thus, closing applications is necessary only if the application stops working or does not respond.
When we end the work of an application, this leads to unloading the application from RAM (short-term memory), and when we need the application again, the device must download it from scratch.
