How to show Battery Percentage on your iPhone
Whether it’s important to you to be able to see exactly what percentage your iPhone’s battery is on at any given moment, or you’re attempting to track and preserve your iPhone’s battery usage, showing the battery percentage in the battery icon can be helpful.
Open the Settings app, and select Battery.
Toggle Battery Percentage to on. It will be green when enabled.
You will now see the battery percentage in your battery icon.
