Have an iPhone? Here's why you shouldn't close apps

They must have realized, when they created this job title, that it ALWAYS sounds like a snarky insult.

So the reasoning is that opening and closing apps uses battery power unnecessarily. But how much power are we talking about here? Will it reduce your usage by a hour? Ten minutes? Two minutes?

There are way too many variables to give a number–but maybe minutes? Powering the screen while waiting longer for the app to launch probably uses more power than ram/cpu difference. The point is micromanaging your running apps, in most cases, gives you worse performance than doing nothing and has been the case for many years. The perception of micromanaging is that you’re extending your battery life by hours. In practice, you’re spending extra time and likely making performance worse. You’re also more likely to be in a situation where you don’t have cell service to redownload whatever you had been looking at previously.
