iPhone Experts Explain Why You Should Use The Secret ‘Yellow Mode’ For Longer Battery Life: ‘Reduces Background Activity’

Low Power Mode

Low Power Mode is the “yellow mode.” When you enable the setting, it automatically conserves battery power so that your phone doesn’t lose its charge so rapidly. But, in return, you’ll have to be willing to give up some ways of using your device (temporarily, of course). Background App Refresh, for example, won’t work and new content won’t be able to update or be fetched. Mail fetching will be halted. And things like visual effects, automatic downloads, and iCloud photo updates will pause.

How to Enable Low Power Mode

To enable Low Power Mode, go to Settings > Battery and then toggle on Low Power Mode. You can keep Low Power Mode on until you’re able to plug in your device to give it a charge.

Generally speaking, the best way to charge your device to prevent it from losing power so quickly is to give it short bursts of charging that keep it charged between 30 and 80 percent. Charging it throughout the day is a better method than waiting until night and charging your phone at one time.
