Once the battery on the device reaches the official number of cycles, it is normal for you to receive a " Service Battery " warning . Thankfully, you can keep track of your battery's charge cycles right inside macOS.
First, press and hold the Option key, click the Apple menu icon, then click the ' System Information ' item . Scroll down to the ' Hardware ' section in the left pane, then click ' Power '. All battery related information will be displayed, including the number of charge cycles.
If the charge cycle here exceeds the number listed on Apple's support page, that's why the system shows the ' Service Battery ' warning . But if you think the number of charge cycles on your device is abnormally high, move on to the next method.
Reset System Management Controller (SMC)
You can try resetting the SMC if your MacBook comes with a non-removable battery.
- To reset the SMC, you must first turn off the device.
- Plug the power adapter or MagSafe into the computer and electrical outlet.
- Simultaneously press Shift + Ctrl + Option and the power button.
- Release the three keys with the power button at the same time.
- Then, press the power button again to turn on the computer. Check the battery status menu to see if the ' Service Battery ' warning disappears.
This is just a little trick. If nothing different happens, you can try the next option.
Recalibrate the battery
This method will be time consuming. However, if you really want to get rid of the annoying 'Service Battery' warning above, try following the steps below. Apple also suggests doing this as a way to 'restore' battery performance every few months. Of course, this timeline depends on your usage frequency:
Charge your battery up to 100% and ensure that the MagSafe charging jack light displays green, indicating fully charged.
Once fully charged, continue using the computer while MagSafe is plugged into a power source; do this for two hours. Then unplug and use until the battery runs out and you will see a low battery warning on the battery status menu. Your Mac will sleep automatically without any warning. For now, just turn it off.
Wait for five hours or more, then connect your Mac to the power adapter or MagSafe and charge it. This will help recalibrate your battery.
In the example in the post, the battery status returned to ' Good ' and the ' Service Battery ' warning is gone.
Take the device to an Apple authorized service provider
If the ' Service Battery ' warning still doesn't go away, maybe your battery has a real problem, and it's time to hand it over to the experts.
