Battery drain randomly

[Gustouk]

Massive battery drain on two cameras yesterday at 56% this morning both showing 4%
Only had 3 recordings of 15 seconds
Very strange as they have been fine up till now

Was the base un-powered for a time ?

Not been unplugged
I did notice one went down from 50+ % mast week so I’ve been monitoring and yesterday one was 56% other 65%
Then this morning on 4% so something has drains it over night
I’ve had them over 4 months so not sure what’s happened
Both still recording and staying on 4%
