The common thought is closing background apps will improve battery life, speed up your phone, and reduce data usage. However, you can actually do more harm than good. It all comes down to how Android was designed to run apps.
Android was specifically made to have a bunch of apps in the background. When the system requires more resources, it will automatically close apps for you. It’s simply not something you need to do yourself.
Plus, it’s a good thing to have apps running in the background. They will launch very quickly when you open them, making your phone feel faster. That doesn’t mean every app you’ve ever opened is sitting there eating up resources. Android will close unused apps as needed. Again, it’s not something you have to manage yourself.
