Google has been gearing up to release a series of Nexus devices including its primary mobile OS update, Android 5.0 L. According to recent information, the upcoming Nexus 6 will be featuring a new and improved battery for extended life whereas the Nexus 8/Nexus 9 will feature a NVIDIA Tegra processor and the Android L sporting a new encryption data. Can Google truly deliver these killer offerings?

Google Nexus 6

The Nexus 6 has been in the headlines for quite some now. Reports vary about what the device will go by. Some claim it will be Nexus 5 (2014), some say it will be Nexus X. According to recent AnTuTu benchmark sighting, the Nexus 6 may run on the upcoming the Android 5.0 L sporting features such as 5.2-inch QHD display, Qualcomm Snapdragon 805 SoC and 3GB RAM.

According to Android Headlines, Google has been sticking traditionally to small batteries for previous models. This means they cannot offer as much battery life. Nexus 5 featured a 2300mAh battery. It was designed based on the LG G2 featuring a 3000mAh battery. As Motorola has been named as one of the possible manufacturers, analysts expect a better life. The Moto X offered decent battery life. Nexus manufacturers traditionally base their devices on their current flagship thus the Nexus 6 may be based on the features and performance of the Moto X. People may see a 3000mAh if Google pushes with it.

Nexus 8

For quite some now, the Nexus 8 has also been called the Nexus 9. According to MoDaco co-founder Paul O'Brien, the Nexus 9 may be released on October 16. The reported manufacturer is HTC although Google has not confirmed anything. Reported features include: 8.9-inch display offering either 2048 × 1440 or 2560 x 1440 pixels, NVIDIA Tegra K1 Denver processor (64-bit), 4GB RAM, or Android 5.0 L. GSMInsider notes that the device may start at $275.

Android 5.0 L

Google's Android L made headlines following its announcement during the I/O conference. It marks Google's efforts on bringing about platform unity starting with the UI interface through Material Design. According to the Washington Post, Android 5.0 L will come with an automatic personal data encryption similar to the iOS 8.

"For over three years Android has offered encryption, and keys are not stored off of the device, so they cannot be shared with law enforcement," Nikki Christoff, spokeswoman for the company, said. "As part of our next Android release, encryption will be enabled by default out of the box, so you won't even have to think about turning it on."
