The new version of Android improves battery life
Android L, the next version of operating system (and that Google filed two weeks) will give greater autonomy to phones and tablets that use it. Google said during presentation that was doing the battery consumption an important point in the successor to Android 4.4 KitKat (what called the Project Volta), as it had done before in the consumption of RAM.
Google released a developer version of Android L; is not the final, which will be available in the next few months, but intended for programmers who have a Nexus 5 or Nexus 7 Tablet (2013) will testing all the changes that this new version brings.
In ArsTechnica took a Nexus 5 tested the battery life with Android L and KitKat, doing the same test (upload via Wi-Fi a Web page which is automatically updated every 15 seconds) to test how much battery lasted. They did shoot twice.
The result: Nexus 5 with Android battery lasted 36 percent more (7 hours 51 minutes against the 5 hours 45 minutes which lasted with KitKat).
This does not indicate that all computers that are upgraded to Android L are to have an identical improvement because the hardware influence of each model, the optimization made by each manufacturer of the Android L code that it includes, etc., but should be a similar number.
How did they do it? In part, no longer using the Dalvik engine to use ART (which is available in a KitKat trial) and that ceases to compile applications when used – every time – to do so only when installed – in the style of a PC, in addition to implementing a series of tools that limit the impact that has on the battery actions such as removing the phone from rest to see if there is activity (one second of this takes two minutes standby battery, according to Google) what makes the smartphone when it goes offline, which allows you to make the applications installed, etc.
The Android L version is available for developers who have a Nexus 5 or 2013 Nexus 7 tablet, and can be installed on a Nexus 4 or 2012 Nexus 7 tablet, courtesy of programming community. For the final version we will have to wait a few months and then while every manufacturer takes to adapt it to their equipment.
