Currently I have 4 mobile mining applications installed on my smartphone, namely Pi network - athene network - sidra chain - cpen network and to be honest my cellphone battery usage is quite wasteful, but if I disable the background feature, the battery consumption becomes lighter, not wasteful. as long as you run your smartphone normally and continue to pay attention to the health of your smartphone, then I am sure your smartphone will be fine when running the mining apk on your smartphone.
