Most of those built-in batteries cannot even be replaced by their owners. I checked our newest MacBook Air. There is no easy way to replace the battery. iPhone? Nope. iPad? Uh uh. AirPods? Ha! See how that works.
Jeffrey did some research a few years ago, then some tests, and came up with what should have been obvious to all of us as the Best iPhone Battery Tip Ever.
Low. Power. Mode. That’s right. Part of the best tips for iPhone battery life is Low Power Mode. Turn it on and your iPhone still works well but uses much less battery. Jeffrey found two more tricks that help extend battery life by a day on the newer iPhones; those with OLED displays (iPhone X, iPhone X Plus, iPhone Xs, iPhone Xs Plus, iPhone 11 Pro, and iPhone 11 Pro Max).
OLED displays are known battery hogs relative to modern LCD displays. Yet, when a pixle on the display is black, it uses hardly any power whatsoever. It’s turned off.
Do the math. Now add it all up.
iPhones have three user-controllable modes. Dark Mode, Lock Screen, Wallpaper. Set your iPhone to Dark Mode, and use black as the setting for the Lock Screen and Wallpaper.
Black. Black. Black.
That translates into no power, no power, no power. And that translates into extra power for everything else. iPhone 11 Pro models get about four or five more hours per day anyway, and Low Power Mode can extend that by another six hours. Dark Mode, and a black Lock Screen and Wallpaper can give you even more; another six hours in my tests.
That means the new iPhone 11 Pro models can do two full days on a charge; or, put another way, a full day of doing almost anything on a single charge. Plus, these iPhones charge much faster thanks to the larger USB-C-to-Lightning charger Apple put in the box this year.
How is that not the best set of iPhone battery tips ever?
