The Nexus 6 will run the upcoming Android version rumoured as 4.5 which may be tipped off during Google I/O event. Sources have hinted major upgrade details Google plans for the newest addition to the next line and so here are list of what people may expect on its release.

Brand New Processor

Google may shift the Nexus 6 to similar processing technology used by the iPhone 5S and Galaxy S5 by incorporating the upcoming Qualcomm's 64-bit processor octa-core architecture. Nexus 5 sports 2.3 GHz quad-core Snapdragon 800 and Nexus 6 according to Digitimes will prefer using Snapdragon 810 octa-core CPU.

Reliable sources expect that Qualcomm will release the rumoured Nexus 6 processor around the Q2 of 2014 which matches the same timeframe of Google I/O 2014. Moreover, Snapdragon 810 SoC is likely to feature four ARM Cortex A57 and A53 chipsets using ARM big.LITTLE configuration for balance and efficient performance.

Lenovo as Maker

Lenovo may have got the rights of Motorola to manufacturer the last Nexus devices during the buyout. Eldar Murtazin tweeted the information which makes Lenovo a strong candidate to produce a Nexus product that focuses on the U.S. market. However, he didn't reveal if it's a Nexus smartphone or a tablet.

Bigger RAM for 64-Bit Support

Processor with 64-bit support enable manufacturers to install bigger RAMs using similar concepts with laptops and computers. Nexus 6 may feature 3 to 4 GB of RAM at least to maximise the processing capability of Qualcomm's Snapdragon 810. It will make the upcoming smartphone quick on loading apps and games, and faster on processing camera images and video recordings.

Upgrading the Camera

If Nexus 5 boasts 8 MP rear camera shooter, expect higher camera lens on Nexus 6 such as 13 MP minimum. As usual, Nexus 6 will have the Optical Image Stabilisation technology, HDR and photo sphere but we also expect something new such as 4K video recording or BSI technology on the device. Google may also upgrade the front camera from 2 to 5 MP.

Android 4.5 Version

There is no solid evidences yet regarding the exact version after Android KitKat and no one knows yet which dessert name will take its place. But several improvements are likely to be discussed during the Google I/O 2014 regarding wireless technologies, gaming experience, accessibility, entertainment and more.

Some notable topics for Android on Google I/O sessions are:

1. Wi-Fi and Bluetooth connectivity

2. Gaming experience on the Play Store

3. Daydream feature

4. Graphics performance

5. Android Cloud storage and services

6. Accessibility

7. Mobile TV

8. Android OS scripting

9. Networking support

10. Battery and audio performances

The Nexus 6 already missed the Mobile World Congress so we are looking within the release date from a month after Google I/O up to the Android's 2014 anniversary when the new version is expected to be released.
