Smart Meter Battery

Afternoon

I’ve recently had a smart meter installed but when not plugged in, the battery lasts barely 3 hours. Is this right? Does it need to be plugged in permanently?

Many thanks

Yes this is correct - charge lasts about an hour and a half. So keep it plugged in. My one no longer will hold a charge so is not working. Does anyone else have this issue?

The IHD should be plugged in permanently, or not used at all. The battery is there for if you decide to test how much energy something uses, you can move it around the home while you turn things on/off.
