Google I/O: Nexus 8 battery life will astonish thanks to Android 4.5

Rumours are buzzing that Google's annual developers' conference, Google I/O, will see the launch of the Nexus 8 tablet Android 4.5.

Rumoured to measure 8.9in and pegged to be the final addition to the Nexus family, the Nexus 8 should pack enough high-end specs to challenge both Android rivals and the twin industry leaders: iPad Air and the Retina-wielding iPad Mini 2.

Intriguingly, the Nexus 7 2014 was the first Android tablet to be loaded with Android 4.3, making it likely that the Nexus 8 will hit shelves with Android 4.5.

This is particularly exciting, because it was discovered that Android 4.4 KitKat contains some experimental code that can help speed up apps. Combined with rumours that Android Runtime will be a default mode in 4.5 (replacing Dalvik), the Nexus 8's battery life will likely be vastly improved because apps will be much faster to load.

However, theories abound the Nexus 8's storage will be compromised. This is because ART takes up slightly more storage space – though since Nexus devices are famed for cutting down on bloatware, it's hoped this won't be too noticeable.

The release date for the Nexus 8 will likely land sometime in July or August 2014, with more details being released at Google I/O in San Francisco on June 25.
