Advance Power save Modes
We believe that the new default settings on Apple iOS v3.3.0 and 1 minute “Power save” described in the blog post will meet the needs of most users.
However, if you do need to squeeze even more from your battery, then we have some more ways to do this available within the Power save options and described below.
Changing the GPS cycle Time Interval
With Power save on, you can use the slide bar to make the time interval longer, so the GPS is in low power mode for a longer period. However, please be aware that extending the time interval will restrict the closeness of the points on your recorded track.
Changing to Stop/Start mode (for longer time intervals)
For time intervals of longer than 5 minutes*, you can switch from “Hi/Lo” GPS mode to “Stop/Start” mode, which actually turns the GPS off completely during the interval.
*Important note for time intervals of less than 5 mins, Stop/Start mode is less power efficient than Hi/Lo, as the GPS uses most power, when it gets a new fix from off.
If you scroll down the GPS settings page you’ll find further controls.
Single Fix Mode
For extended multi-day expeditions, we have added a “single fix” mode for ultimate power conservation, where neither track recording, nor buddybeacon, nor active navigation is required. In this mode the GPS is always off, until manually invoked using the GPS icon. As the name suggests, a single fix is achieved, then the GPS is turned off again until next requested. Scroll down to find “single fix” control. (see screen grab)
Changing the Auto-Disconnect delay
If you are not happy with a 1min auto disconnect, when app in background or screen off, this can be changed and might be useful if you need a quicker GPS fix.
Once again, be aware that Hi/Lo, Start/Stop & Single Fix modes are overridden when active navigation used, as this requires continuous location information.
