1. The second utility is called Fanny, and it keeps an eye on fan speed and CPU temperature of the Mac, also within Notification Center. This tool is likely most useful for Mac laptop users but many desktop users like to know what their fan is doing and what temperature the CPU is running.

Made to look after an optimum use, XRG (X Resource Graph) is one of the best Mac temperature monitors that certainly inform you about CPU, GPU, battery health, memory status and even the weather. It is an open source which, like any other monitors that perform Mac CPU temperature check, is sure to keep you updated with system activities.

About the lithium-ion battery in your Mac notebook

Mac notebook batteries use lithium-ion technology. Lithium-ion batteries charge quickly, are long-lasting, and currently provide the best technology to power your computer.

All rechargeable batteries are consumable components that become less effective as they get older—and their age isn't determined only by time. A battery's lifespan depends on its chemical age, which is affected by factors such as its temperature history and charging pattern. As your notebook's battery ages chemically, its charging capacity gets smaller.

With these tips for maximizing battery performance, you can get the most out of all your Apple devices. And with battery health management, your Mac notebook can take battery optimization even further.

How battery health management helps

The battery health management feature in macOS 10.15.5 is designed to improve your battery's lifespan by reducing the rate at which it chemically ages. The feature does this by monitoring your battery's temperature history and its charging patterns.

Based on the measurements that it collects, battery health management may reduce your battery's maximum charge when in this mode. This happens as needed to ensure that your battery charges to a level that's optimized for your usage—reducing wear on the battery, and slowing its chemical aging. Battery health management also uses the measurements to calculate when your battery needs service.

While battery health management benefits your battery's long-term lifespan, it can also reduce the amount of time your Mac runs on one battery charge when capacity limits are applied. If your priority is making your Mac notebook last as long as possible before recharging, you can turn the feature off.

When battery health management is turned on, your battery's maximum charging capacity might be limited. Although the feature is designed to improve your battery's lifespan, the limited maximum capacity might update your battery status menu to indicate a need for service. Your Mac calculates when to recommend service for your battery based on battery health management being continuously enabled.

How to control the battery health management feature

Mac Os Versions

Battery health management is on by default when you buy a new Mac notebook with macOS 10.15.5 or later, or after you upgrade to macOS 10.15.5 or later on a Mac notebook with Thunderbolt 3 ports.

If you want to turn off battery health management on a Mac notebook with an Intel processor, follow these steps:

1. Choose System Preferences from the Apple menu , then click Battery.
2. Click Battery in the sidebar, then click Battery Health.
   
3. Deselect 'Manage battery longevity'.
   
4. Click Turn Off, then click OK.

A new version of Sensei, a popular Mac system monitoring tool, was released today for M1 Mac users. The update adds support for real-time monitoring of fan and temperature sensors in the new M1-powered Mac Mini, MacBook Air and MacBook Pro.

Sensei is the first app in the world to feature support for viewing thermal information on the new Apple Silicon Macs. The sensor system on these new Macs is completely redesigned, and now features hardware that is usually found in devices like the iPhone.

In case you wondered how similar the M1 Mac is to the iPhone: The temperature sensors in the new M1 Macs seems to be taken straight from iOS devices, and are reporting as A11 (iPhone 8) hardware.

One of the biggest new features in the M1 Macs is the small thermal footprint of the new CPU. Initial reports by M1 users who’ve tried Senseis thermal monitor have confirmed that the new Macs do indeed keep their temperatures extremely low, even under heavy workloads.

An interesting observation is that the M1 Macs seem to have a greater amount of temperature sensors, with a larger portion of them located on the new Apple Silicon SoC. This is likely in order to benefit the asymmetric multiprocessing techniques employed in the new CPU architecture, where the CPU switches between high-performance cores and high-efficiency cores dynamically in order to maximise performance per watt.

With access to this new thermal information, tech reviewers and ultimately consumers will be able to better compare the performance in the new Apple Silicon Macs towards previous models and PC competitors.

Sensei supports macOS 10.15 and later and offers a 14-day full trial.
