The way you handle your iPhone apps could be hurting battery life and performance
This important nugget of information is easy to ignore and you might not think much of it, but if it’s something that you do, you might want to drop the habit as you are not doing your iPhone any favor by closing apps.
There is a myth that closing apps running in the background improves performance and boosts battery life but that’s not true. When you move to a different app, apps that you were previously using are set to a suspended state in which they don’t use system resources.
Loading an app from scratch also means that it has to be initialized from storage, which theoretically makes your iPhone slower.
If you don’t like charging your iPhone very often, there are other steps you can take to make it last longer, including dimming the screen and enabling Low Power Mode.
