Interval every 5 minutes at least without being connected to the power AC

[mocamiguel]

The application in android is great when I have the phone connected to the power, but when it works with the battery stops sending the location in the indicated interval and does it every 5 minutes at least. (I have Samsung Galaxy S4 with android 5.0.1 in case it helps to give some clue)

I have included lines 53 through 64 here

But keep doing the same. Does the app on Android continue to work well for everyone with an interval of 1 minute or less? (I have tested in 20 seconds and 1 minute, but both unsuccessfully)

Please, I hope your help, I do not know how to solve it.
