Good news for Android people!
Google recently released the latest version of Android, 6.0 Marshmallow, "M". This coincided with the release of the latest Nexus devices, 6P and 5X, which come with 6.0 out of the box.If you own an older Nexus device, 6 or 5, Google just released OTA (Over-the-air) update for your phone. All you need is a data connection to update your phone. DO NOT go to a store to do this. The update is about 700MB in size (702.5MB to be precise). Not a lot of noticeable differences visually as the 5.1.1 was quite sleek in itself and Google decided to continue with that. One remarkable thing was a huge improvement in battery life.At the end of the day my battery is usually around 55. Today it was above 65. Google has explained this feat on their official page in depth. If you do not own a Nexus device and would like to know when your phone will get the update, please follow the link.
