Many of those who own an iPhone are constantly looking for tricks to increase the battery life of their devices, and this is because the applications they use daily can consume a lot of energy, sometimes for things they really don't need.
Today I'm talking about a very simple trick that allows you to save a lot of your iPhone's battery power by blocking the access of certain applications to GPS location when you don't use the application at all and it still monitors.
The location made by the applications uses not only the GPS, but also the mobile connection or a Wi-Fi connection, so in the end we are talking about a high consumption of energy for something that you may not need at that moment, or at some other time .
An application like Facebook, for example, can do localization even when it is not used and opened in the main screen, and in 99% of cases this localization consumes a lot of energy unnecessarily because the collected data reaches Facebook and is not useful to us.
In this situation, there are many applications, especially those for voice guidance for GPS navigation, and for those that request access to the location when they should not have it, there is the option to disable access when the applications are not in use.
To restrict the access of applications to localization when they are not used in the main screen, you just have to go to Settings > Privacy > Location Services, Settings > Privacy > Location Services and locate the applications that have activated the function Always, Always, and disable it or choose While in Use, When using the application.
By doing this setting, you can extend the battery life of an iPhone quite a bit, depending on how often you use the applications that normally require access to location data, although they practically do not use us in any way.
