Eufycam 2c battery life

I bought a couple of eufycam 2c cameras at the begining of the year. 1 has needed recharged once, the other 4 times. Recently I moved the one from the back garden where the dogs were triggering it all the time to another location. And within about 3 weeks its gone flat again. Could it have a faulty battery.
Anyone else had this issue.

In one location you have a 2c with good battery life? If so… fully charge the 3 week one and switch them. You will know real quick if it’s the battery or it’s location.

I had a 2c with bad batt life…. Swapped the cams and it was the location. Changed the cam to the bigger cam 2 pro…. And finally to the wired c24 outdoor. Trees and shadows in the breeze was killing my batteries.

I run solar on all my 2c so always fully charged saves having to take them down to recharge can buy on ebay
