There is one feature in the Google Nexus 5 that users constantly complain about and that is its short battery life. The device boasts of good features, including a sharp display, but that means consumption of more power, forcing its users have to charge their handsets twice or even more every day. Gamers end up charging multiple times. 

Adding to users' woes, the LG Nexus 5 comes with a non-removable Li-Po 2300 mAh battery, which means they have to use it until they are ready for an upgrade as there is no chance of a battery replacement.

However, Google's new operating system Android M, now confirmed as Android 6.0 Marshmallow, could do wonders to the Nexus 5 by improving its battery performance tremendously. The popular smartphone will be greatly benefited by the new firmware if one were to go by the developer's preview. 

According to a test done by German blog Computerbase (via 9to5 Google) on two Nexus 5 devices running on Android 5.1.1 Lollipop and Android 6.0 Marshmallow, battery standby time increased by almost three times with the new software. 

When left for 24 hours in standby mode, the battery of Lollipop run Nexus 5 was down by 12% while the one powered by Marshmallow was down by only 4.5%, according to the test done by the website.

When kept on standby for 48 hours, the battery of the device running on Google's 6.0 OS was down by 9%, whereas the one running on Lollipop was down by 24%.

It may be noted that the test was done with first developer preview of Android 6.0 Marshmallow, so there is high chance of an even better battery performance with the final version of the software.

Google has already released three developer previews of Android 6.0 Marshmallow to devices such as Nexus 5, Nexus 6, Nexus 9 and Nexus Player before its official launch in September.

The Nexus 5, which currently runs on Android 5.1.1 Lollipop, will get Android 6.0 Marshmallow when released. The device sports a 4.95-inch True HD IPS+ capacitive touchscreen with 1080 x 1920 pixels (445 ppi pixel density), is powered by Qualcomm Snapdragon 800 processor, comes packed with 16/32 GB internal memory, 2 GB RAM, 8 MP main camera, 1.3 MP secondary snapper and a non-removable Li-Po 2300 mAh battery.
