Have you ever wondered, "Why is my battery yellow?" When Low Power Mode is enabled, the battery icon at the top of your phone will appear yellow, and features like mail fetch, background app refresh, automatic downloads, and some visual effects will be reduced or disabled until it is turned off. This saves your battery life and can keep your iPhone running longer. Personally, I use Low Power Mode all the time to maximize the time between charges. There are two primary ways to turn on Low Power Mode. The first way requires you to go to Settings:

Open the Settings app.
Tap Battery.
Toggle on Low Power Mode.

That's how you turn on Low Power Mode on your iPhone via Settings.
