iStat Menus is a deservedly popular system monitor — it puts CPU, memory, disk, network and sensor readouts in your menu bar. But if you bought it mainly to keep an eye on your battery, you’re paying for a lot of breadth and getting only a shallow battery module.
If battery is your real focus
- iStat shows charge, but no charge control.
- No device batteries (iPhone, iPad, AirPods, Watch).
- No battery insights — forecast, coach, benchmark, heat log.
A battery-focused alternative: Mac 4 Breakfast
Mac 4 Breakfast is built around the battery: health, cycles and temperature; charge limiting and Energy Mode; every Apple device; and an insight layer — for one one-time price ( compare).
When iStat Menus is still the right call
If you want a live readout of CPU, GPU, network and fans across the whole system, iStat Menus remains excellent — it’s simply a different tool. Many people happily run a system monitor and a dedicated battery app side by side.
