r/GalaxyS21 on Reddit: What's the verdict on closing apps vs leaving them open in background?
June 11, 2023 -
I remember when the phone first came out people were split into two camps, the first being conventional knowledge that closing apps saves battery, and the other being that leaving them open in the background actually saves battery because the phone doesn't need to load it fresh when you go back to it. Has there been a consensus?

The reasoning behind the latter is because closing the app requires them to be reopened when the time comes, which in itself cause increased battery usage. However, it's felt negligable for a while now because of Android's phone usage adaptation. Imo, if you want to really save, close apps you use once in a while and leave common apps like social media apps running in the background. I've honestly not seen recent tests done on this but optimisations over the years have been so good it feels like it shouldn't even be considered as a huge battery impacter. Aside from phone usage, phone signal really hits the battery as well as screen brightness imo

Battery activity On my battery activity it says I use my Roku app for two hours but the background activity is 4 hours. That sounds like a lot for background activity. How can I cut that out?

June 11, 2023Does closing apps on your iPhone save battery life? The surprising answer is no – here's why
Developer here: when an app goes to the background, it delegates its tasks to the system. The app can only execute in background for a few seconds (finishing a download for example) before the system freeze it. For example, if the app is using location tracking, that’s the system that wakes up the app for a few seconds to update whatever it wants, until the next update. For notifications, that’s the system that receive them, the app is generally not involved. Etc… If the app is following the Apple guidelines and there is no bug in iOS, an app in background should not be able to drain battery. Apple is very strict on that. That’s a big difference with Android, at least in the older release: an app cannot do what I want on iOS. Source: https://developer.apple.com/documentation/backgroundtasks/choosing-background-strategies-for-your-app If your app needs computing resources to complete tasks when it’s not running in the foreground, you can select from many strategies to obtain background runtime. Selecting the right strategies for your app depends on how it functions in the background. The system grants your app a limited amount of time to perform its work once it enters the background. […] Once your work completes, call endBackgroundTask(_:) before the time limit expires so that your app suspends properly. The system terminates your app if you fail to call this method. To preserve battery life and performance, you can schedule backgrounds tasks for periods of low activity, such as overnight when the device charges. […] the system decides the best time to launch your background task. Your app may require short bursts of background time to perform content refresh or other work; […] The system decides the best time to launch your background task, and provides your app up to 30 seconds of background runtime. Background pushes silently wake your app in the background. They don’t display an alert, play a sound, or badge your app’s icon. […] The system decides when to launch the app to download the content. […] your app has up to 30 seconds to complete its work. You get the idea. More on reddit.com

Additionally, it’s an app you typically open and keep open for a long time, leaving the screen on for longer.
