Of course, testing and benchmarks are required to see just how much (or little) of an impact this will be for the Google Glass, but it ought to result in a better battery life for Glass users. After all, one of the major thorns in the use of Google Glass had always been its battery life so hopefully the XE16 update will be able to do its bit and help prolong the device’s battery life.
Those who are about the update the Google Glass might want to prepare themselves beforehand for a rather lengthy process. One will first get updated to XE12.1, which is actually laying the foundation for the big update, and once the KitKat installation process kicks off, you need to wait for approximately 30 minutes or less for the entire thing to be done. Do expect to enjoy a new boot animation in Glass, too, once the update is complete.
