Apple finally has an official position on the practice of force-closing unused apps on iPhone to preserve its battery. The tech giant said this week that the method does no benefit battery conscious users in any way.
In a recent e-mail, Apple’s senior VP Craig Federighi told a concerned user that keeping iPhone apps in multitasking mode does not drain battery life even if they are left unused. According to reports, many people dutifully hunt down and force shut idle apps on their iPhones due to the myth that it would save battery life.
The e-mail debunking the myth was publicized yesterday on a popular tech site.
Tech experts explained that iPhone apps do not drain system resources when not used. When you switch away from them they just enter a frozen state. Once you get back, they spring back to life.
This is why force-closing idle apps may have the opposite effect. Whenever you close an app, the handset tries to reload the app many times over, which can put an additional strain on your iPhone and even suck out its battery life.
Still, there are some apps that do not enter a frozen state such as the GPS navigator and the music player.
But there are some sure techniques to prevent your iPhone’s battery from dying so fast. You could, for instance, shut down Background App Refresh, a feature that keeps refreshing idle apps.
Nevertheless, the feature is smart enough to know when exactly to refresh the apps. It does so when it senses you plugged in your iPhone or you are actively using it. So, don’t expect to save too much battery.
Instead, you should focus on location services running on each idle app. These are some of the greatest energy drainers. But to make sure that your efforts do pay off you should check the “Battery Usage” section to see what apps exactly are the least energy efficient.
Yet, be wary that not all types of smartphones force idle apps into entering a frozen state. For Samsung Galaxy, Nokia Lumia, and a multitude of Android-powered handsets it is highly advisable to shut down unused apps when multitasking.
Experienced users have noticed that crashing apps on iPhones also drains the energy out of its battery. These crashing apps are slippery because they look to be closed while they keep munching on system resources. One clear sign that there may be a problem with a crashing app is your iPhone becoming hot.
