One thing that unites all wearables would have to be their lackluster battery life, but it looks like researchers over at Microsoft's WearDrive project might have solved this.
The researchers are using a RAM-based system that doesn't rely on a battery, something that would save battery life in wearables. The way this works is by pairing the wearable with a smartphone through Wi-Fi or Bluetooth, with the more energy consuming apps processed on the smartphone, instead of on the wearable where it consumes the important battery life.
Microsoft's WearDrive energy saving system was tested on an Android-powered smartphone, with the researchers noting that there was a "negligible" impact on smartphone battery life, while there was a 300% improvement on battery conversation on the werable. The we arable was also 800% faster than normal application runtimes, which is a huge achievement. The WearDrive also deactivates when it's out of range of a paired smartphone.
