Collect accelerometer readings while an app is suspended

Windows 10 Universal App uses 1-second interval on DispatcherTimer to collect and make deductions on the device's accelerometer readings.

Requirement is that this process should continue even when the user suspends the app (not 'terminated').

One possible solution was Registering with Background Task using time trigger, but it allows a lowest interval of 15 minutes compared to the required 1 second.

You can use the extended execution session. By using this session, you can prevent the app from suspending even if the app go to background. But...this is an important thing... this is a sort of 'best effort' service. OS can 'revoke' your extended execution ANY time.

In my experiences (with my 1GB-memory phone), if you run the only 1-2 apps, the target app can keep running. but, 4-5 apps running, the target app's extended execution are revoked intermittently.
