[BUG] Battery status in main window takes few seconds to show and sometimes flickers

[mwisnicki]

Describe the bug
If I open the app and navigate to any screen then navigate back to main window it takes about 3s for battery status to show up.

Additionally in some cases the battery status will disappear while on main screen only to reappear second later.
I also have bluetooth address sometimes disappearing in System information screen for a second.

To Reproduce
Steps to reproduce the behavior:

1. Open App
2. Go to System
3. Go back

Expected behavior
The battery status is cached for reasonable time and always visible when app is open (unless app couldn't obtain it).
