Share This:

Are you having trouble with your Mac’s battery health displaying “Service” in the menu bar instead of the maximum capacity? You may be worried that it means it’s time to replace the battery; however, there can be other reasons why this warning appears. Here we will discuss how to reset the System Management Controller (SMC) on an iMac, Mac Pro, or Mac mini in order to potentially remove the “Service Battery” warning.

First, shut down your Mac and unplug the power cord. Wait 15 seconds with the Mac unplugged and then plug in the power cord and wait 5 seconds. Then turn on the Mac.

Next, hold down the Shift + Control + Option + Power buttons together for 10 seconds and then release them. Make sure to press all four buttons together at once. This will reset your System Management Controller (SMC).

Finally, power up your MacBook and check the battery status menu to see if the “Service Battery” warning has disappeared. If it has not disappeared then it is likely that you have exceeded or gotten close to the average 1,000-cycle charge count for your model of Mac and will need a new battery replacement.

When dealing with a Service Battery message from your Mac it is important that you understand both the reason behind its appearance as well as how to reset SMC so that you can get back up and running again quickly and easily!

Removing the Battery Service Message on Mac

To get rid of the battery service message on Mac, first, make sure your MacBook is powered off. Then hold down the Shift, Control, Option, and Power buttons all at the same time for 10 seconds. After releasing those buttons, power on your Mac and check the battery status menu to see if the “Service Battery” warning has disappeared. If it has not gone away, you may need to get in touch with Apple Support or take your Mac to a local Apple Store so they can take a look at it.

Understanding the Meaning of ‘Service Battery’ on a Battery

Your battery may say “Service Battery” in the menu bar for a few reasons. Firstly, it could be an indication that your battery’s health has deteriorated beyond repair and will need to be replaced. Alternatively, it could also mean that your battery is not being properly charged due to a hardware issue with either your device or the charger you are using. Additionally, the message could also appear if your device has gone through an excessive number of charge cycles or has been exposed to extreme temperatures. If you are experiencing this issue, it is recommended that you contact Apple support or seek assistance from a certified technician as soon as possible.

Resetting the SMC on a Mac

To reset your SMC Mac, start by shutting down your Mac and unplugging the power cord. Wait 15 seconds with the Mac unplugged, then plug the power cord back in and wait 5 seconds before turning the Mac back on. This should reset your System Management Controller (SMC) and get your Mac back up and running. If you continue to experience issues, you may need to take additional steps such as resetting the NVRAM/PRAM or troubleshooting other hardware issues.

The Impact of Resetting SMC on Battery Life

Yes, resetting the SMC (System Management Controller) on an Apple laptop can improve battery life. This is because the SMC is responsible for managing power consumption and performance settings, such as the speed of your processor, fan operation, and other settings that allow your laptop to run more efficiently. When these settings become corrupted over time due to software and hardware updates, resetting the SMC can restore them to their original factory settings, allowing your laptop to be more efficient and ultimately improving battery life.

Does Resetting the SMC on Mac Delete All Data?

No, resetting the SMC (System Management Controller) on a Mac does not delete any of your data. Resetting the SMC on a MacBook Pro will simply reset certain system settings and controls, such as power management and battery settings, to their original defaults. This can help fix some issues you may be having with your Mac, such as unexpected shutdowns or fans running too loud. It is important to note that if you are using macOS Ventura or Monterey, or need to upgrade or download macOS Ventura, you may lose data during the process. Therefore it is always recommended to back up your data before proceeding with any reset or upgrade.

Bypassing SMC on MacBook Pro

To bypass the System Management Controller (SMC) on your MacBook Pro, you will need to disconnect all power sources, including the MagSafe power adapter and any external batteries. Once this is done, press and hold the power button for 5-10 seconds. The fans should start to spin at their maximum speed and you will have successfully initiated an SMC bypass. Be aware that this will disable certain features such as sensors, so make sure to re-enable them once you have finished your work.


In conclusion, Macs are reliable computers that offer a great user experience. Although they may require regular maintenance and updates to keep them running at peak performance, they can last for many years with proper care. Additionally, Macs come with an impressive battery life, allowing users to get the most out of their devices without having to worry about frequent recharges. With their powerful hardware and software features, Macs are a great choice for anyone looking for a long-lasting computer to handle all their needs.
