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 your smartphone’s battery life: 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 POWER SAVING MODE FOR?


This new mode will allow you to maximize your battery life. You will minimize your consumption by using only the essential functions of your TREKKER-X3. Whether it’s a day trip or several days, you will always remain reachable by disabling the most energy-consuming applications (social networks, GPS tracking…).

HOW TO ACTIVATE POWER SAVING MODE?


There are 2 ways to display Power Saving Mode:

  • Swipe down the taskbar and activate Power Saving Mode by clicking on the icon.
  • Go to the “Settings” of your TREKKER-X3, then “Battery” and click on “Power Saving Mode” in the “three dots” menu at the top right.

To access this mode, you need to install the latest update. Go to the applications menu of your TREKKER-X3, click on the “Update” icon and the loading will start automatically.


How does Power Saving Mode work?

  • When activated, your screen will display in shades of gray and the brightness will be reduced by 50%.
  • Your usual interface will then be replaced by a new, more streamlined one. Only 8 applications can be displayed on the main screen, of which 4 are customizable.
  • You will only have access to basic applications:
  1. Phone
  2. SMS / MMS
  3. Internet. Here, your connection will switch from 4G+ to 2G, except when you open your browser, the connectivity will be in 3G+. As soon as you open another application, the connection will switch back to 2G.
  4. SOS Function
  • You can add 4 applications (native or not) by clicking on the “+” shortcut. Note, you will not have access to the Play Store and therefore no possibility to add a new application.
    In the taskbar, only notifications will appear. All other icons will disappear.
    Your smartphone settings will only be accessible via the "three dots" at the top right and will also be restricted here:
  1. Wi-Fi
  2. Bluetooth
  3. Various cellular networks (NFC, Bluetooth...) and airplane mode
  4. Display
  5. Sounds and notifications
  6. Location
  • Power Saving Mode will cut off various connections: Bluetooth, NFC, Wi-Fi, and Location to minimize consumption. But you will still have access to your mobile data.
  • To disable the mode, press the "three dots" at the top right and choose "Disable power saving mode".

How to enable automatic triggering of Power Saving Mode?

Go to "Settings" then "Battery". Select "Power Saving Mode". In the "Activate automatically" tab, you can choose to enable the feature trigger at different thresholds (between 5 and 35% battery remaining).

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

How to install the update on your TREKKER-X3?
