Millions of iPhone users just realized that they need to press this blue button every week if they don’t want to drain their battery

## Don’t let your iPhone’s battery life silently shorten. It’s easy to find out the “culprit” that’s draining your iPhone’s battery and take action to stop it. Go to the “Settings” app on your iPhone and select the Battery item. It’s an item with a blue background, with a white battery icon above it. By clicking here, you can view information about the battery’s performance. Most importantly, you can check what’s draining your battery, choosing between 24-hour and 10-day view. You can see the battery level and activity represented as a graph. Scrolling further down, you can see the battery usage of each app. The information here will show you which apps are draining the most battery (as a percentage). If you tap the blue “Show Activity” button, you’ll get information showing the battery usage of apps in the background. There are some apps that can drain your battery even when you’re not actively using them. Apps like WhatsApp, Instagram, and Apple Mail can all be using battery in the background. If you see an app that you don’t use often, but it’s draining your battery significantly, that’s a bad sign. At this point, you need to consider whether you can change the settings on that app to prevent it from draining the phone’s battery. If you don’t really need it, delete the app. It’s important that you check your Battery regularly as your per-app usage habits may change over time. Also, even if an app doesn’t use much battery for a week, an update or some tweak can cause it to start draining your battery later. If you find yourself constantly experiencing battery life issues, the most likely cause is an app that’s draining your battery.
