Checking battery drain is the process of determining how much power your device’s battery is using. This can be useful for identifying apps or settings that are draining your battery too quickly, and for taking steps to improve your device’s battery life.
There are a number of ways to check battery drain on different devices. On Android devices, you can go to Settings > Battery to see a list of apps and how much battery they have used since your last charge. On iOS devices, you can go to Settings > Battery to see a graph of your battery usage over time. You can also tap on the “Battery Health” section to see information about your battery’s health and how to improve it.
