Report: Android 6.0 Marshmallow nearly triples Nexus 5 battery life


Alex Ruiz Android Marshallow

Battery life is one of the most important metrics by which we measure how useful a smartphone is day-to-day, so getting it right or wrong is a big deal.

Fortunately, Google’s next major operating system update could solve battery life woes for the next generation of Android devices.

According to German blog Computerbase, Android 6.0 Marshmallow – otherwise known as Android M – offers significant battery improvements compared to Android 5.1.1 Lollipop.

The website compared both operating systems running on a Nexus 5 (2013) handset in standby mode.

After 24 hours in standby, the Lollipop lost 12.5% of its charge.

That’s in contrast to the Marshmallow Nexus 5, which saw a paltry 4.5% loss of charge over the same period.

Interestingly, that ratio continued perfectly over 48 hours, with the Lollipop handset slipping by 24% compared to a 9% fall from the Android 6.0 device.

The data was then extrapolated to predict a 200 hour standby time for Android 5.1.1, compared to a 533 hour standby time on Android M.

It should be noted that the Android M software running on the Nexus 5 was a developer preview edition.

As such, it doesn’t necessarily accurately reflect the battery life capabilities of the final software release, expected this autumn.

It’s also worth noting that these tests were run on handsets in standby mode, so we’d expect vastly different results from phones with the screen on and apps running.

But why is the battery life seemingly seeing such significant improvements with the latest operating system?

It’s probably down to a new feature called Doze, which Google announced earlier this year at its annual I/O developer conference.

Doze works out whether you’re using your device or not, and sends it into a sleep mode during periods of inactivity, reducing battery drain.

Of course, we’ll have to wait for the final software release to really see how much impact Doze will have on battery life.

Google is expected to launch Android 6.0 Marshmallow proper later this year, with the software reportedly set to debut on two new Nexus handsets – the LG Nexus 5 (2015) and the Huawei Nexus 6 (2015).

Do you think Google has finally cracked the battery life conundrum? Let us know in the comments.

Brilliant news if accurate, one of the main failings of Windows and Android to me is that standby is a huge battery drain on the device when compared to iOS, previous android/windows tablets tap out after only a couple of days in standby where as my iPhone/iPad can last days with no use and have only a small reduction in the battery life in comparison

For a product thats supposed to be your sofa device, being able to last in standby is a huge plus

fingers crossed this won't translate to tiny batteries on the new N5 and N6 because "doze means they are more power efficient so don't need as large batteries" when it does naff-all for people who actually USE their devices!

Although I've noticed the battery drain with Android devices, I've found Windows Phones to be nearly as battery efficient as iOS. Not quite, mind you, I do have to admire Apple's ability to produce efficient software, but Windows Phone is far better than Android (from my experiences). We'll see how Android 6.0 and Windows 10 Mobile compare.

The standby battery life on my N5 is acceptable. The battery drain problem is when I am actually USING the phone. I hope they can address on Android 6.
