介绍:
1. For many iPhone users, swiping up to close recently used apps hasbecome second nature, assuming it improves performance and battery life. But that’s actually not the case and I’ll explain why right now.
2. When it comes to speed, completely closing all your apps delivers a slower experience whenthey’re relaunched. The iPhone’s operating system is designed to manage CPU and memory resources on its own. Optimizing apps to deliver a fast and responsive experience, without the user even thinking about it. But when you force the operating system to close out every app, it doesn’t have the chance to optimize performance.
3. Instead, the app is flushed out of system memory, meaning what you were doing and where you leftoff will be forgotten, and the app will have to reload all of its content instead of simply staying on standby. iOS simply continues to display it in the app switcher for the sake of convenience.
4. Now if you want to continue swiping up to close apps just because it’s satisfying, I completely understand. Just knowthat it isn’t providing any functional benefit while likely hurting battery life and negatively affecting performance.
对于许多 iPhone 用户来说，向上滑动以关闭最近使用的应用程序已经成为第二天性，想当然地认为它能提高性能和电池寿命。但实际上不是这样的，我现在就来解释一下原因。
说到速度，完全关闭你的所有应用程序，在重新启动时，会带来更慢的体验。iPhone的操作系统被设计用来自行管理 CPU 和内存资源。优化应用程序以提供快速和反应敏捷的体验，用户甚至不需要考虑这个问题。但是，当你强迫操作系统关闭每个应用程序时，它就没有机会优化性能了。
相反，应用程序从系统内存中被清除，这意味着你当时的操作和你停下的位置将被忘记，应用程序将不得不重新加载其所有内容，而不是简单地保持待机状态。iOS 只是为了方便才继续在应用程序切换器中显示它。
现在，如果你想继续向上滑动来关闭应用程序，只是因为这令人满足，我完全理解。只要知道这不会提供任何功能上的好处，同时可能损害电池寿命并对性能产生负面影响。
