‘Why is my iPhone battery yellow?’: How to enable an iPhone’s Low Power Mode to conserve battery

If the battery icon on your iPhone has turned yellow, it means you're in Low Power Mode.

Apple added this feature with iOS 9 in 2015 to extend battery life. When your battery gets down to 20%, you'll receive a message asking you if you want to enter Low Power Mode. You'll get the message again when you hit 10%, if you didn't turn it on at 20%.

In Low Power Mode, your screen will auto-lock after 30 seconds, no matter how you configured your normal auto-lock settings. Features like background app refresh, email fetch, and "Hey Siri" will be turned off while you're in Low Power Mode.

If you're tempted to use this feature all the time to save your battery, you'll probably find the hassle is not worth the reward. It's not as easy to use your iPhone with this mode on.

However, Low Power Mode can add hours to your battery life, which may be a lifesaver if you're stuck without the ability to recharge.
