As we were telling you a few days ago, the next Android version is said to come with serious improvements to the battery life. And now, according to some early tests coming from ArsTechnica, it seems that this is indeed turning into reality. The single viable solution to address problems with the battery life was to increase the amount of mAh, but now it seems that Google is really looking into the problem.


The upcoming Android L release is said to improve the battery life on Android devices with Project Volta, as early results from the developer preview seem to show. Ars Technica performed a detailed analysis of the battery life on the Nexus 5 running stock Android 4.4.4 Kitkat and Android L. The smartphone was run through a browser-based battery life test and on Android 4.4, it lasted 345 minutes.

The Android L developer preview has a much better result, scoring 471 minutes before the battery got depleted. This is quite a difference, and it shows that the next Android version could add two more hours of battery life. Of course, these are early tests which have been taken on a single smartphone and they are bound to change in the future. Still, they show a great deal of where Android is headed.

At the moment, we are looking at a 36% increase in battery life which has been possible thanks to a more efficient performance of the device’s wakeup triggers. According to some internal testing done by Google, it seems that one second of device wake-up time could eat two minutes of standby time, and this is what Android L tries to address. It comes with a new JobScheduler API which allows database cleaning and backups functions to take up less time.

Also, as we have previously mention, the switch to the Android Runtime (ART) instead of Dalvik is going to improve battery life during active use. Here are some more details about another battery saver feature in the next Android version:

Android L also has a “battery saver” feature that lowers the device performance and cuts the background data and screen brightness when the device hits 15-percent battery, but we disabled this feature for our tests. We like to have our devices at full power, and we don’t want a hyper-aggressive phone-crippling feature messing with our results. Presumably, you could gain even more runtime by turning the battery saver on. This test is more about the general under-the-hood improvements that are running all the time.

Albeit the results are based on developer preview and this also require future apps to be slightly modified to make better use of the battery adjustments, it’s already clear by now that you’ll be able to live without your recharging cable for a few more hours.
