Investigate resource usage spikes on android devices

[lewisl9029]

Saw the app at top in android power usage after running for a few days.

Looks like it was caused by using silent mode for the background-mode plugin and the app re-initializing itself over and over again.

Looks like that wasn't the only cause. Saw it happening again with the new release build, along with almost constant network usage. Saw almost 0 cpu and network activity in debugger though... And restarting the app fixed it...

Reopening for tracking but seems like it might be an issue with some native code (cordova or plugins).

Disabling autostart for now due to this.
