A user on this Product Hunt said that kinds of monitoring app such as iStatmenu, Menubar apps, that constantly poll the CPU for data, can drastically impact battery life. Is it true?

  • I use istat menus and I have not noticed significantly less battery life while using it. That's just my personal experience. – NoahL Jan 17 '17 at 6:51

Battery is affected with power consuming operations; cpu, hdd, bluetooth, wireless, etc.

So, yes. Amount of the cpu usage may drastically impact battery. Battery life is proportional to the frequency of charges/discharges.
