Unlike Lollipop, Marshmallow 6.0 is a version of Android that promises significant battery changes. Those who have already installed the update know what I am talking about. I have been testing Android 6.0 on my Nexus 5 since the final version was released, and today I am going to show you how the Twelve Power Management function behaves. I advance that the results are impressive.
What the Twelve?
Discovered at the time of the Android M developer preview, Twelve is one of two energy-saving features introduced by Android 6.0. The second is called App Standby. Finally maturity, the Twelve function primarily aims to optimize and reduce processor and network activity when the device is not used for a certain interval. In addition, the second function is to limit background application synchronization.
Confirmed by Google, Twelve and App Standby are an integral part of Android 6.0 (API 23) and will be adopted in future OS releases to be released. After ProjectVolta's lean results, his successor Twelve is one of the best news from Marshmallow.
How does Twelve behave?
Take the example of a user who leaves the smartphone off and placed on a table for a period of time. After a certain point, the screen of the device is turned off and at that time the Twelve acts.
In Twelve mode, the system attempts to conserve battery power by limiting application access to wireless networks and heavy processor-intensive tasks. After an interval (and periodically) Twelve deactivates and opens a window for applications to access the network to update their information. This saves energy without losing the functionality of each app.
When this window closes again, the system returns to Twelve mode and suspends application network access, blocking any synchronization and notifications. Over time, and depending on its use, the function learns and evolves to improve battery economy in the event of longer inactivity and when the device is connected to a charger.
When the user unlocks his smartphone, Twelve automatically turns off and allows normal use of the device.
My test with Twelve
First day – normal use
Being a Nexus 5 owner, I wasted no time and installed Android 6.0 Marshmallow on my device to get all the latest Twelve mode news.
Knowing the catastrophic autonomy of the Nexus 5 (in all previous Android versions), I can say that the new version has conquered me. In the past, I had to recharge my Nexus 5 in the middle of the day. Thanks to Twelve and the Standby App, my Nexus 5 has really become less dependent on its charger and now able to handle a full day without recharging (with normal use of the device).
To usher in the first day with Android 6.0 on my Nexus 5, I wanted to preserve my habits, which boil down to:
- 2 hours of browsing (in applications and on the internet);
- 20 to 30 minutes from Hearthstone;
- Music by Play Music that occupies 3/4 of the day.
Believe it or not, the Nexus 5 still had 41% of battery life at eight thirty at night (having been charged at 3 am). This is even more impressive considering that my Nexus 5 was purchased in November 2013. Since then, the person who sold me said he used it every day and never replaced the battery. By the way, I plan to change it soon. Who knows the new one can last up to a day and a half?
Day Two – Limited Use
The next day, I decided to moderate my use to better understand how these two new functions work. The result was even more amazing. After a full day, the battery percentage was 25%. As in the previous test, I had fully charged the device and disconnected from the charger at 3 am. During the second day, I performed the following activities:
- 1 hour and 30 minutes of navigation (applications and web);
- 15-20 minutes from Hearthstone;
- Music activated on 3/4 of the day.
Third day – low intensity use
For the third and last day of the test, I decided to use my Nexus 5 lightly. This allowed the "Twelve" function of Android 6.0 Marshmallow to really show where it came from. After a day of light use, there was still 55% of the battery at half past nine at night. I had unplugged the charger at 2 in the morning. On this day, I did the following:
- 1 hour and 10 minutes of navigation (applications and web);
- Music on 3/4 of the day
Twelve and App Standby features are not available for Nexus devices only. They will be distributed along with Android 6.0 Marshmallow to all handsets receiving the new version of Android. Results may vary, but we can expect a significant improvement in the autonomy of Android smartphones. For more information, check out the Android Developers page.
