Lockdown Mode is the top paramount security/privacy and feature for Librem 5 this mean that all sensors is shutdown.
Purism recently enabled the Hall sensor of the Librem 5 so i tested the compass-sensor and lockdown mode it worked both!
Big thanks to @angus.ainslie
Nice, what application is that? I cannot find a compass in the store …

…when finish reboot your GNU DEVICE then go to setting to calibrate the app, when calibrating becareful not fall you device. It mandatory the calibrate in order to work like a charm.
I did a test today for power saving by using LockdownMode + InactiveMode, and got spend 4% of batt per hours, i know that Purism still working on powersave in all modes, so i guess we will get 2 or 3% per hours on LockdownMode + InactiveMode, which it awesome work from Purism. I not tested LockdownMode+ActiveMode yet. But doing this test it let me know that WLAN controller Plus Modem controller it eating to much battery, so it will good to exploit the L5 modem, and wash all the userspace to get better batt on the modem, also get a newer WLAN controller to support better battery life mode including compat to StR.
Kudos for Purism.
Also thanks to Kyle Rankin for supporting the idea of an icon to LM.
So i finished the full test today on powersave on L5 and it reached 18HRS on LM + IM.
This test was mainly with phone ON but screen OFF must of the time, plus all sensor shutdown.
