No notification on power restore

The power went out. I got a notificiation that had happened, a few hours later I got another saying it was on battery power (?) - the timing of that was a bit odd and I assumed that but ok.

Power was out for a few days and the status just said there is a power cut, it did not say whether still alive on batteries or not. You state 24hr battery time, could that actually stretch to a few days?

A few days later the power came back, all good, but I received no notification. I was told that I would, and it would have been helpful.
