Your iPhone’s screen is one of the biggest battery drains on your device, and is often responsible for the appearance of the yellow battery icon on the iPhone.
There are several settings that you can adjust which can help curb the battery usage on your iPhone, but one of the easiest and least impactful options is the Auto Brightness setting.
By enabling Auto Brightness on the device you are allowing it to adjust the brightness of the screen based on the lighting in your current environment. This means that the screen won’t be unnecessarily bright when you’re indoors or in the dark, meaning that less battery power is used to illuminate it.
