How frequently can i call this service without affecting the performance of the system and network?

Hi Ishan,
Thank you for the excellent API.
I am developing a desktop application that will notify me about the battery and give a notification if battery is too low.

I would also like to record the signal strength throughout the week and show a chart of it everyday that i can decide where is the best place to put the router and other fancy stuff.

My question is, how frequently can i call this service without affecting the performance? can i call it every second or should i make the peroid longer? How about network usage, CPU and RAM?

Appricate your support and i will be sure to attribute your library and link it to your repo.
