Microsoft Research to Enhance Wearable Battery Life

Microsoft Research to Enhance Wearable Battery Life

Wearable devices might be in demand but the battery life is a matter of concern. Most of these devices run out of power very easily. The solution to this problem is now here. As a part of WearDrive project of Microsoft, researchers have found a way to improve the battery life of these devices. They have done it by using a RAM-based system which does not depend on a new battery. Microsoft Research employees Anirudh Badam and Ranveer Chandra will present the paper at the USENIX Technical Conference this week which states that if the requirement to read and write data to a wearable’s onboard flash memory can be removed, then battery life can be improved significantly.

WearDrive System

Microsoft claims that its WearDrive system will let applications to have an 8.85X better performance and use up to 3.69X less energy than standard methods. This energy saving system was tested on an Android phone where it was seen that it had insignificant impact on the battery life of the smartphone and the energy conservation for the wearable had improved over three times. In fact the runtime of the paired wearable was also more than eight times faster than normal application runtime.

No Requirement of Smartphone

By reducing the things that is being done in the background, the battery can be made to last longer. This is done by offloading many background functions to a smartphone. The other wearable or fitness band works normally till a smartphone is detected nearby. It then uses the phone via Bluetooth or Wi-Fi to carry out the activity as much as possible.

With this unique approach, the wearable will work normally without the requirement of a smartphone. If you are going out for a jog, you can leave your phone behind and still take advantage of the fitness band. As you again come near the smartphone, the wearable will unburden the functions to the phone and save battery in the process.

Anirudh Badam, a researcher at Microsoft said, “Everyone has been thinking of reusing what exists for mobile devices,” Chandra said, according to a Microsoft research publication. “What we’re saying is, ‘It’s a different paradigm. It’s a different usage scenario.’”

The developers of Microsoft Band do not have any plans right now to integrate WearDrive on the current generation’s device. Testing is still on and Microsoft Research hopes that other projects will arise which will revolve around the WearDrive concept.

Do you think this is a good step by Microsoft? Do you use any wearable? We would like to hear your thoughts in the comments below.
