Why is My iPhone Battery Icon Yellow?
Normally, your battery icon is white and turns green when plugged in for charging, but sometimes your battery icon turns yellow. So what does a yellow battery icon mean? Is it a sign of severe battery damage or something is wrong with your phone? Nope, it simply means your phone is in Low-Power Mode. This great additional feature on your iPhone helps extend the battery life by making some changes to the functionalities of your iPhone. It dims the brightness, stops the push and fetch of mail, and stops services like Hey Siri, which turns off the background applications that keep refreshing, which saves a lot of power in the battery and helps it run longer.
