It's almost time for the massive Google launch, but the world just can't wait for details on the hotly anticipated Nexus 6P and Nexus 5X. Recent leaks revealed more details on both mobiles ahead of the upcoming launch date on Tuesday, Sept. 29.

According to Forbes, the full PowerPoint presentation for Google's launch was unveiled on Reddit, listing down more specs of the Nexus 6P.

The Huawei-designed phablet will be delivering a better battery life with the updated 3,450 mAh battery, according to The Verge. It's a significant upgrade from the 3,220 mAh of the previous Nexus 6. Further helping users conserve battery life is the mobile's Doze feature, which makes the battery life last longer by putting the phone in sleep state when resting. Another feature, App Standby, conserves battery with the user's regular apps.

As a high-end phablet, the Nexus 6P is unveiled in the presentation as "the first all-metal Nexus flagship smartphone." It looks smart and sophisticated with a 5.7-inch screen that's made of Gorilla Glass 4. Other details of the upcoming phone include a smart Qualcomm Snapdragon 810 v2.1, dual front-ported speakers, USB Type-C charger and fingerprint sensor.

The device is available in four colors (aluminium, graphite, frost and gold) and three memory options (32GB, 64GB and 128GB).

The Nexus 5X is equally interesting as Amazon revealed when it leaked the details for the LG-made phone. According to a report from Tech Times, Amazon posted the smartphone's details in their India website ahead of schedule. The company took down the listing soon after.

Most of the features confirmed previous speculations on the much-awaited Nexus 5X. The smartphone will include a 12.3-megapixel rear camera and five-megapixel front camera, Android v6 Marshmallow OS, 1.8 GHz Qualcomm MSM8992 hexa-core processor, 2GB RAM, 16GB internal memory, 2,700 mAH battery and a 5.2-inch touchscreen with 1080 x 1920 pixels resolution and 423 pixels per inch (ppi).

The report also revealed new colors of the smartphone including Ice Blue, Charcoal Black and Quartz White.

According to a report from Bidness Etc., Google will be launching more products aside from the Nexus 6P and 5X. The Android Marshmallow will be launched at the same time, reportedly offering a more stable and efficient performance for Android users. The new Chromecast is also expected to be a big release with upgraded WiFi support and an improved Chromecast app.

A brand new device is also reportedly being launched during the Google event: Chromecast Audio. The product is a streaming media service that features multi-room audio and is supported by popular services including Pandora, Rdio, Deezer and Spotify.
