Huawei P9 and P9 Plus, the autonomy is not only a question of battery – Wired.it

What are the ingredients to make a good smartphone? Each manufacturer has its own recipe, but there is one aspect that, usually, end users do not want to see overlooked: l'autonomy. No one likes a cell phone that goes off at the second coffee break of the day, but slip the batteries are always the most capacious under the body of the phones is usually not enough to solve the problem. That’s why the batteries 3000 and 3400 mAh battery is present inside Huawei P9 and P9 Plus is only one of the aspects that allow the smartphone to arrive with confidence at the end of the day and beyond. The technologies adopted in the two products are not absolute novelty, yet often they are explo ited all together to provide performance out of the ordinary.

The Android operating system is seasoned with the gui EMUI developed by Huawei, which, among other things, allows you to monitor and restrict with maniacal precision the energy consumption of every single app and component of the phone.

The platform can highlight the activities that consume the battery abnormally or that take advantage of resources when they should remain closed, and the user can decide whether to keep them as they are or to block some functionality.

in Addition to the actions taken on individual apps, smartphones offer the three floors of the consumption of different: the first gives priority to performance, always pushing to the maximum the processor to ensure fluidity and speed in all situations; the second balance individually and with care the network connections and the computing power required to the CPU of the phone; the third disables all of the internal components with the exception of those reserved to the calls and messages, and can get to double your battery life remaining.

And then the settings of the automatic power on / off make sure that the phone is put completely to rest for the days and times established, and is activated only when necessary. In this way, the smartphone saves energy during the night even if you forget to turn it off, all while remaining usable for functions such as waking up in the morning: just set the car phone is turned on in time for the notification ringtone.

those Who want to save even more energy finally, you can restrict the efforts of the graphics processor and the display with a special mode that reduces the resolution of the screen from 1920×1080 to 1280×720 pixels: the definition of the contents to the screen will decrease substantially, but the autonomy will benefit from it equally. The mode is activated in parallel to each of the three floors of consumption, in this way, you can earn valuable minutes in emergency situations, taking active the other functions of the smartphone, such as Wi-Fi connections and cell phone.
