Battery low in brand new ADT ST hub

While trying to fix many connection issues with ADT Smartthings devices, I unplugged the power from the hub and it went into batter mode, and noticed the battery is only at about 30%. I bought the hub a few days before and have a regular v2 hub with a separate set of Zwave devices and generally dont have any issues. Is this normal? Am having so many issues with this thing.
