Apple is currently researching sideways approach to lengthening the battery life of the iPhone. Rather than go through the expensive process of developing longer lasting batteries, the Cupertino giant is conceptualizing a means of using icon like status indicators that will will work on the iPhone’s display, even when the it’s locked and the backlight is turned off.
The tech being talked about concerns the use of two different backlights, with one consuming dramatically less power than the other. It’s really rather clever and it goes a little something like this:
“The primary backlight system may block light from the secondary backlight system except for those one or more regions. Thus, the size and shape of the status indicator may be set by sizing and shaping the transparent or semitransparent regions of the primary backlight system. In addition to setting the size and shape of the icon, the color of the icon may also be set by adjusting the color of the light provided by the secondary backlight system.”
In less technical ters, a system like this would essentially mean that a number of colored status icons representing anything from text message or email updates, to missed calls or a low battery warnings could be transmitted to the user with a minimum drain on the battery.
Very clever indeed, though obviously this is at least one, if not more, iPhone hardware revisions away. The future’s bright (but not so bright that it suck all your battery’s life).
