Power Saving Mode : optimisez votre batterie

In addition to offering mobiles and smartphones with exceptional battery life, CROSSCALL, the leader in outdoor mobile technology, has found THE solution to extend the battery life of your smartphone: Power Saving Mode, a new feature available since the latest update on the TREKKER-X3.

But what is it for? How does this mode work? All the answers to your questions are here.

WHAT IS THE PURPOSE OF POWER SAVING MODE?


This new mode will allow you to maximize your battery life. You'll minimize your power consumption by using only the essential functions of your TREKKER-X3. Whether it's a day trip or a multi-day outing, you'll always be reachable by disabling the most power-hungry applications (social media, GPS tracking, etc.).

HOW DO I ACTIVATE POWER SAVING MODE?


There are 2 ways to display the Power Saving Mode:

  • Swipe down the taskbar and activate Power Saving Mode by clicking the icon.
  • Go to the "Settings" of your TREKKER-X3, then "Battery" and click on "Power saving mode" in the "three dots" menu in the upper right corner.

To access this mode, you must install the latest update. Go to the applications menu on your TREKKER-X3, click on the "Update" icon, and the download will start automatically.


How does Power Saving Mode work?

  • By activating it, your screen will display in shades of grey and the brightness will be reduced by 50%.
  • Your usual interface will then be replaced by a new, cleaner one. Only 8 applications can be displayed on the main screen, 4 of which are customizable.
  • You will only have access to basic applications:
  1. Telephone
  2. SMS / MMS
  3. Internet. Here, your connection will switch from 4G+ to 2G, except when you open your browser, when the connection will be 3G+. As soon as you open another application, the connection will switch back to 2G.
  4. SOS function
  • You can add 4 apps (native or otherwise) by clicking the "+" shortcut. Please note that you will not have access to the Play Store and therefore will not be able to add any new apps.
    Only notifications will appear in the taskbar. All other icons will disappear.
    Your smartphone's settings will only be accessible via the "three dots" in the top right corner and will also be restricted here:
  1. Wi-Fi
  2. Bluetooth
  3. The different cellular networks (NFC, Bluetooth, etc.) and airplane mode
  4. The display
  5. Sounds and notifications
  6. The location
  • Power Saving Mode will disable various connections: Bluetooth, NFC, Wi-Fi, and Geolocation to minimize power consumption. But you will still have access to your mobile data.
  • To disable the mode, tap the "three small dots" in the top right corner and then select "Turn off power saving mode".

How do I activate the automatic activation of Power Saving Mode?

Go to "Settings" then "Battery". Select "Power saving mode". In the "Automatically activate" tab, you can then choose to activate the feature based on different thresholds (between 5 and 35% battery remaining).

When the phone reaches the selected threshold, it automatically switches to Power Saving Mode.

How do I install the update on my TREKKER-X3?

The update is currently being rolled out*. To install it, go to the applications menu on your TREKKER-X3, click on the "Update" icon and the download will start automatically or press "INSTALL".
