Iphone 4 battery life draining fast

You will know the feature is activated because the battery icon in the top-right corner will turn yellow. Smartphone displays are bigger and brighter these days, but those crisp screens keeping you awake at night can be murder on your battery life.

The good news is you can easily dim that brightness. First, activate auto-brightness. Your phone will then adjust its brightness based on your current lighting situation. If you have enough light to see, the screen will turn itself down and save battery life. A slider is also accessible via the Control Panel ; pull down from the top-right corner on iPhone X models or swipe up from the bottom on older iPhones. Press lightly on the brightness icon and move the slider up or down.

This, however, will make a number of useful apps much less so. Your weather app won't know where you are for the latest forecast, and you won't be able to ask Google to produce driving directions based on your current location. As such, Apple provides the option to customize how most apps use location data: Never, While Using the App, or Always. Select "While Using the App" for Google Maps, for example, and the app will only ping your location when you open it.

It won't continue pinging your location in the background, draining battery. When you close an iOS app, it will keep running for a bit until entering a suspended state. With Background App Refresh, however, those suspended apps can still check for updates and new content—a process that can drain battery life. You can disable Background App Refresh completely or just for certain apps.

Battery Life of iPhone 4S Draining Too Fast? Try Calibrating the Battery

To disable on an app-by-app basis, return to the previous menu and find refresh-heavy apps, like email or social networking platforms. Toggle them off. This shouldn't have any effect on how the app works, but might take a moment longer to surface new information when you return to them. Having email on your phone can be super convenient and data fetches mean your inbox is always displaying the most recent messages.

But you can customize how these fetches occur so the phone isn't draining its battery by constantly searching for new messages or calendar items. Here, you can deactivate Push data entirely or choose how often you want your iPhone to check for new content on the various apps that support it. If your screen lights up with a preview of every notification you receive, it's consuming power with each text, breaking news alert, or Twitter follow. Cutting down on these interruptions can save your battery and sanity.

One option is to find a notification from an app you'd like to silence, swipe left, and select Manage. Here you can choose to have the alert delivered quietly, which means it will go to your Notification Center, but won't show up on the Lock screen, play sounds, or show a banner or badge icon. Here, you can also turn off notifications for this app completely.

Using Wi-Fi is a great way to cut down on the amount of data you use, but it doesn't do wonders for your battery. Your phone continuously searches for nearby Wi-Fi networks, which is why the list of available networks constantly changes when you're out and about. Just remember to turn it back on when you get home or to a location with steady Wi-Fi, lest you use up all your cellular data. Similarly, Bluetooth and AirDrop are constantly looking to connect, but there's no reason for them to be active at all times. You can also turn AirDrop off from the Control Center.

Swipe down from the top-right on iPhone X and above or from the bottom of the screen on older iPhones. Press down slightly on the menu options on the top-left. Tap AirDrop in the menu that appears and choose Receiving Off. If you're in a real jam for power, put your device in Airplane Mode, which turns off all your phone's wireless features.

Calls and texts won't come through, but you can still connect to Wi-Fi if necessary for iMessages and other tasks. The easiest way to do this is to look for the airplane icon in the Control Panel and tap it. It's also accessible in Settings; just toggle it on.
