They look to reduce the "chatter" between the device and the network, which significantly drained its energy than screen brightness and other settings targeted by low power modes.

Vodafone developed an API (application programming interface) enabling apps and operating systems, like Android's Wear OS, to reconfigure their network communication.

They emphasized the importance of battery life for wearables, like smartwatches and other devices behind their collaboration. They tested changes like making the watch connect to the network intermittently instead of constantly and releasing the channel through which it was transmitting more quickly, Vodafone director Santiago Tenorio said.

Given the small battery size in smartwatches, changing these parameters could extend the life of the device "very significantly," Tenorio said. The API could save users enough power to last until the end of a long run, he said.

The tech derived from Vodafone's 2017 project with elite runner Kenenisa Bekele to break the two-hour marathon barrier.

The amount of data transmitted by sensors in the attempt exhausted a smartwatch battery in less than an hour, Tenorio said. Vodafone disclosed that the technology could be available in Wear OS in the coming months with "many more" wearables partners interested in the API.
