When the battery of your iPhone gets down to 20%, a window will appear on the screen warning you about it, and it will ask you if you want to put the device in Low Power Mode. If you say yes, then the battery icon will turn yellow accordingly. Once you have a chance to charge the phone again fully, the battery will show as green once more.
