An updated document on Apple's website says the only time users should close an app is when it becomes unresponsive or crashes.
Advances in battery technology have not yet kept pace with improvements in smartphones. This means that most flagship smartphones require daily charging and only a few can last 2 days if the user is careful.
While manufacturers like Apple have their own tricks to maximize battery life, that doesn't stop people from coming up with their own tricks. The problem is a trick can have the opposite effect that we often do. their own hack, and a new report has brought to light one that may actually be doing the opposite.
Specifically, in Apple's recent recommendation, the company said users should not close applications immediately when switching to another application by swiping, instead they should only do it when the application is not running. response or crashes.
This information is noteworthy because many people have the habit of closing applications they do not use because they think they operate in the background and closing them will help improve battery life on the device. But the reality is, when a user switches to another app, the apps the user was using before will be placed in a paused state without using system resources.
Most apps use a very small amount of power in the background, so users won't gain much benefit from closing them. In fact, closing an app as soon as you're done using it to save battery is counterproductive, as some experts believe that it takes more energy to load an app than to go back to using it.
Loading an app from scratch also means that the app has to be initialized from storage, which should theoretically make the iPhone slower.
If you don't like charging your iPhone as often, you can take other steps to help your battery last longer, including reducing screen brightness and turning on Low Power Mode.
