Battery saving location mode

Your Redmi note 7 uses 3 location modes to determine your exact location. The high accuracy mode, which uses either one of GPS, Wi-Fi, Bluetooth or mobile networks to pinpoint your location. Although this mode gives the most accurate location, it consumes a lot more battery than the others because the GPS sensor in your phone uses more power. Hence in order to save battery power, especially during travels, you can use another mode called Battery Saving mode which essentially does not use GPS and collects location information from Wi-Fi, Bluetooth or mobile networks to pinpoint your exact location. Since it does not use GPS, it requires less power. Another mode is the Device only mode which uses only the device GPS to provide your location information. To choose the Battery Saving mode,

  • go to Settings->Additional Settings->Privacy->location->Battery saving. Whenever you want to get accurate location information, you can manually turn on the GPS sensor from the menu.
  • Another option that can be turned off from the above menu is the Google Location History which sends information to Google about your location periodically. This is a useless feature for the average Joe and can be turned off to increase battery life.


Whenever you use an Android, you will have to add your Google account to your phone and by default, Google will sync everything associated with your account to your phone.

YOu can choose to turn off the sync for app data, documents and Google drives as shown in the picture below. You can also untick the option to download attachments from the Gmail app as shown in the picture above.
