Samsung Galaxy S7 might contain an interesting function called Always On Display, not being new or revolutionary, but useful enough to say that I would like to see it implemented in Apple's iPhones when they have OLED screens.
Samsung registered the trademark Always On Display at the US Patent and Trademark Office, so they would intend to use it in a product and considering that presentation of the Samsung Galaxy S7 approaches with rapid steps, we can conclude that she will reach him.
With the function Always On Display, Samsung Galaxy S7 it could display notifications, the clock or information about the weather without the screen being fully lit when displaying the information, this system being implemented a few years ago including in Motorola or Nokia terminals, but under other names.
According to the documentation for this technology, the implementation of the function Always On Display in Samsung Galaxy S7 it would generate a consumption of 1 percent of the battery every hour of the day, so not so much as to matter significantly, the economical energy could even extend the autonomy of the device.
At the moment, no one knows if Samsung will implement the function Always On Display in Samsung Galaxy S7, but the idea of displaying information on the screen without turning it on completely and without consuming a lot of energy is one that Apple should take over.
