The Little-Known Tip That Can Save Your Dying iPhone 6 Battery

Clarification: Using the grayscale option does not really help much with battery life due to the fact that iPhones have LCD screens, which feature constant backlighting. Using this function in conjunction with adjusting the brightness on an iPhone should help conserve battery life.

Many Apple fans consider the iPhone to be the Mary Poppins of the mobile sector, practically perfect in every way. However, iPhones do have one persistent issue; they suffer in terms of battery life. This is largely due to slowly developing battery technology coupled with Apple’s insistence on keeping its smartphones thin.

However, there is a feature on the iPhone that helps the device maintain its battery life, and its good name. A simple flip of a switch in settings can save an iPhone on a waning battery from certain death. Users can now activate grayscale mode on their iPhone by accessing in the devices’ Settings, General > Accessibility > Grayscale. Users should be able to activate grayscale mode on most iPhone models.

Though the grayscale feature is actually an accessibility feature intended for colorblind users, its alternate function is quite useful in a pinch. Activating grayscale mode helps to conserve battery life because color displays steal away battery life faster than black-and-white screens. Decreasing the display brightness on the iPhone 6 in addition to activating grayscale mode can also help save power on a dying battery.

Grayscale features can be found on many newer phones like the Samsung Galaxy S5 and the HTC One (M8). These devices include an Ultra Power-Saving mode, which turns the display grayscale along with other battery-conserving functions. Activating this mode can conserve a battery at 10 percent for up to 24 hours. Though the iPhone 6 does not have a similar power-saving mode, the option to set its screen to grayscale is the next best thing. Users can access a grayscale settings shortcut by triple-tapping the home button on an iPhone.
