When your device is running low on battery, pull up Control Center from the bottom and reduce the screen brightness to the minimum. Additionally, you can enable Auto-Brightness by accessing Settings > Display & Brightness and toggling Auto-Brightness on.
Utilize Low Power Mode
Since the iOS 9 update, Apple introduced Low Power Mode, which can extend device battery life by over 40% when activated. To conserve iPhone battery, users should enable this useful feature by navigating to Settings > Battery > Low Power Mode and toggling the switch to ON as shown below.
Starting from iOS 8 onwards, Apple provides iPhones and iPads with the ability to monitor real-time app battery usage since the last full charge. This makes it easy to identify which apps are draining the battery the most, allowing for adjustments to be made accordingly to conserve battery when necessary or forcibly closing those apps to prevent further drain. You can access this information by going to Settings > Battery.
Charge Smartly
4. Disable Background App Refresh feature
iOS's smart multitasking feature allows apps to continuously update with new information, but you may not need all apps to do this. Turning off unnecessary background-running apps will save more battery, such as Google Chrome, Drive, stock market apps, etc. To do this, go to the Settings > General > Background App Refresh and choose to disable apps that aren't essential to you. You can even toggle the Background App Refresh switch to OFF to disable background app refresh altogether for all apps.
5. Turn off Location Services
By default, during app installation, location services are often recommended for access to assist in the app's usage. However, apps using location services can rapidly drain your device's battery. Therefore, you should review which apps have GPS access.
To turn off location services, go to Settings > Privacy > Location Services. Here, tap on any app name to choose permission for location access with options Never, While Using the App, or Always.
6. Enable Airplane Mode in weak signal areas
Your iPhone or iPad will constantly check your network signal and consume more energy if the signal is weak. Even if you're not using the device, the phone battery still drains. So, if you don't need to access data, make calls, or use location services, you can put your phone in airplane mode. To do this, simply open Control Center by swiping up from the bottom of your iPhone or iPad screen and tap on the airplane icon.
7. Disable notifications for apps
Continuous push notifications on your phone when connected to the internet significantly impact battery life. If it's not essential apps like phone calls or messages, you should block all notifications to reduce annoyance. Go to Settings > Notifications, select the app you want to turn off notifications for, and toggle this feature to OFF as shown below.
8. Perform factory reset.
If you've tried all the measures suggested by Mytour above and still feel that the battery drain issue hasn't been resolved, you can resort to performing a factory reset. You can follow the steps in the article on how to Reset iPhone, iPad that we shared earlier.
