I recently switched to a custom ROM from stock. The first screenshot is what I see after a few hours on cell standby, where "retrieve system internal status" service is responsible for ~%2 of battery consumption.
The weird thing is - don't recall ever seeing this service on stock ROM, pressing on it for more info it looks like a kind of "umbrella" service package.
What's more after regular usage, making a call, browsing, etc. this service pretty much disappears from the list in battery usage.
Searching about it shows nothing other than that "retrieve system status" is a kind of permission and not a service... so what is it exactly?
