Samsung pushes new battery-saving technology with Galaxy Note7

Yesterday’s launch of the Samsung Galaxy Note7 saw the introduction of some impressive new features. But whilst Samsung’s iris scanning may have generated all the hype, the tech giant also debuted a battery-saving technology which promises an extra 35 hours from a single change.

Although the Samsung Galaxy Note7’s power-saving mode largely got overlooked yesterday, its implementation is actually highly innovative.

The way Samsung has gone about achieving such impressive figures is to reduce the screen resolution and lower the display brightness. This is combined with the more traditional battery-saving tricks of reducing device performance and disabling background network activity.

Lowering the screen resolution is an interesting concept, as whilst 1440 x 2560 displays of devices like the Samsung Galaxy Note7 produce excellent sharpness and clarity, they are also very power hungry.

But running such a high resolution on a 5.7-inch screen has given Samsung scope to make some gains. With the pixel-dense display of the Samsung Galaxy Note7, is is possible to lower the screen resolution considerably and still be left with a usable display.

There are two levels to Samsung’s power-saving mode. Using Mid, the display drops down to a 1080p Full HD experience, whilst Max implements a 720p standard HD resolution.

Although the ability to change screen resolution is a standard feature of laptops, it is not a facility that has ever been implemented by the manufacturer of a high-profile smartphone.

The ability to effectively alter the screen resolution of the Samsung Galaxy Note7 gives the handset a wide range of use case scenarios. For instance, a resolution of 1440 x 2560 is ideal for using the smartphone with a Samsung Gear VR headset, whilst a 720p display can provide a lifeline when working on-the-go with no access to a power socket.
