The Android 6.0 Marshmallow, also called Android M, which is expected to debut on the upcoming the LG Nexus 5X and the Huawei Nexus 6 (2015), was first announced at the Google I/O 2015 event that was held in June this year. Following the arrival of Nexus 2015 smartphones, the Google Nexus 5 from 2013 and the Nexus 6 from last year are expected to receive the Android 6.0 Marshmallow first.

The Android 6.0 Marshmallow Developer Preview is already available to Nexus devices such as the LG Nexus 5, the Motorola Nexus 6, the HTC Nexus 9 and the Asus Nexus Player. Therefore, it is a clear indication that as Google has done before, its newest OS upgrade will be first made available to Nexus devices before it hits other OEMs.

According to a report from 9 to 5 Google, while testing the first Developer Preview of the Android 6.0 Marshmallow on the LG Nexus 5 from 2013, it was found that new OS improves the battery life of the handset by threefold. The LG Nexus 5 as well as the Google Nexus 6 is expected to receive the Android 6.0 Marshmallow upgrade within few weeks after the release of the final version of the OS, PC Advisor reported.

It further stated that the flagship smartphones from other brands like Motorola, Samsung, Sony and LG would also get the new firmware soon. However, some devices may receive the update very late as there are many devices that are yet to receive the Android 5.1 and Android 5.1.1 Lollipop updates.

Android PIT’s report stated that the Android M would receive a new RAM manager that allows users to check the RAM consumption of different apps. It will also arrive with automatic backup and restore function for apps. The Android 6.0 Marshmallow will bring improvements to Google Now, Google Chrome, Google Photos and more. It will also improve the overall performance of the device.
