Since Apple rolled out iOS 13, many iPhone owners have reported serious issues with battery drainage. Many users have experienced their batteries going from full charge to just 20% within a couple of hours. There have also been reports of iPhones overheating more easily and spontaneously rebooting, even when the phone is not in use.

How to Fix iPhone Battery Drain

If your iPhone battery is draining rapidly, there are a few things you can try help fix the problem. Most are fast, easy ways to fix the problem and increase your battery life.

  1. Close faulty apps. A faulty app may be draining power from your iPhone. Generally, quitting an app on your iPhone doesn't improve battery life, but if something is wrong with the app, it might be causing a problem. You can find out if an app is using too much battery by going to Settings > Battery, then looking at the open apps that are using battery. Look for anything that's using a high amount of power and close the app, if necessary.

  2. Connect to Wi-Fi or turn Wi-Fi off. You could be beyond the range of your Wi-Fi or your cellular network so your phone is in constant search mode. If your iPhone can't connect to Wi-Fi, or it has no service from your mobile carrier, it will continue to search for a network to connect to, thereby draining battery. You can turn off your Wi-Fi and prevent it from trying to connect automatically, or put your phone in Airplane Mode to reduce the drain.

  3. Adjust brightness. The brightness at which your iPhone displays can have an impact on your battery life because it takes more power to generate more light. Try turning off auto-brightness, then setting your screen brightness to a dimmer setting, or enable Dark Mode. It changes the color theme on your device to darker colors that require less battery power.

  4. Place your iPhone face down when receiving notifications. Every time you receive a notification on your iPhone, your phone's screen will light up. The more notifications you receive, the faster your battery drains.

    However, if you leave your iPhone face down, this can help you avoid battery drainage. Your iPhone will still receive notifications, but the screen will not light up. If you can avoid the compulsion to check every notification you receive, you can stop your iPhone battery from draining too quickly.

  5. Turn off push mail on your iPhone. When your iPhone's email settings have Push turned on, your device is constantly checking your email servers to see if there are any new communications, using power in the process. As the name implies, Push Mail maintains a constant connection that looks for any new emails and then pushes them to your iPhone as quickly as possible.

    By changing your Push Mail settings to Every 15 Minutes, you can stay in the loop without your iPhone battery draining too quickly

  6. Disable Raise to Wake. One of the functions that iPhones automatically use is the Raise to Wake feature, which turns on your iPhone's screen every time the device is picked up or moved around. This may save you the hassle of having to press the power button every time you want to view the screen, but it causes battery drainage every time the phone is moved.

    Go to Settings > Display and Brightness, then toggle the Raise to Wake switch to off (gray). Turning Raise to Wake off will greatly improve your iPhone's overall battery life.

  7. Configure widgets and notifications. The Today View gives you today's date and current time, but the main function is to house widgets that let you access your favorite apps. However, each of those widgets requires battery power to maintain their connection and keep data relevant. Reducing the number of widgets will help stop your iPhone battery from draining too quickly.
