Forget this common gesture when using your phone. Contrary to what you believe, it does more harm than good.
Like many users, you regularly launch the same apps on your smartphone. Mail, SMS, WhatsApp, Camera, Gallery, Web Browser, etc. And they usually stay open in the background when you’re using another app. And when the smartphone experiences a little slack, when it becomes less responsive, your first instinct is probably to close those that seem unnecessary to you at the moment. Likewise, when the battery starts to run low, you probably rush to quit apps that are running but are not needed. A reflex which seems full of common sense but which nevertheless serves absolutely nothing. Worse, it is even counterproductive not only for the fluidity of your smartphone but also for its battery.
When you switch from one app to another, the one that is in the background is simply put to sleep. It no longer consumes energy and therefore does not draw on the battery. Likewise, it does not use the resources available on the smartphone either. When you scroll through background app windows, the image that appears is nothing more than a snapshot, a sort of screenshot, of the state the app was in. app at the time of switching. Nothing else. And whether it is an Android smartphone or an iPhone, the principle remains exactly the same.
The worst thing about this reflex is that it is also counterproductive. Exiting the app from sleep and restarting it consumes more energy than just waking it up from sleep. Many processes are reset during the launch phase but are simply reactivated when you switch the app back to the foreground. And you lose both autonomy and performance! If your smartphone starts to slow down, the best thing to do is to restart it. And if its battery shows signs of weakness and you cannot recharge it immediately, lower the brightness of the screen, one of the most energy-consuming elements on a smartphone.
