Using an old Galaxy S4 as a security camera -- battery life is a problem

[Android Central Question]

Hi folks,

I have an old S4 and was thinking of using it as a security camera. I tried a handful of apps from the Play store, and they all work for a while, but they seem to drain the battery faster than it can charge (using the original S4 wall charger). Any suggestions on how to achieve this?

New battery? From memory you can still put those huge fat batteries in that device...
