There’s nothing more convenient than saying good bye to those little scribbled shopping lists. Keeping your eyes on an e-list open on your phone is so much better. But maybe you are at the end of a long day. You probably wouldn’t want your phone to die on you, right? If your display stays active for as long as the app is open, then you might notice it drains your battery rather quickly. To prevent this from happening, simply go to the 3 lines menu – Settings – Display. Make sure you un-check the ‘Display stays active when the app is running’.
