When your Mac’s battery is low, it can seem slow. Your Mac starts to conserve power when the battery gets low. So, things that use much power, like animations and graphics, may not work as smoothly as they normally would.
If you’re finding that your Mac is slow on low battery, you can do a few things to help speed it up again.
If your Mac is running slowly on a low battery, there are a few things you can do to try and speed it up. One thing you can try is closing any unnecessary apps that may be running in the background. You can also try turning off any visual effects or animations that may be running.
If your Mac is still slow, you may need to reset your PRAM or SMC. You can reboot your device without a CMOS battery.
MacBook Battery Throttling
If you own a MacBook, you may have noticed that your battery life isn’t what it used to be. In fact, it may seem like your battery is draining faster than ever before. The good news is that there’s a reason for this, not because your battery is dying.
The bad news is that the reason is something called “battery throttling.
What is Battery Throttling?
Battery throttling is when the processor in your MacBook slows down to preserve battery life. This can happen when your MacBook runs low on power, or the processor gets too hot.
Throttling can also happen if you use certain apps that are known to be power-hungry. The good news is that battery throttling doesn’t mean your MacBook’s battery is dying. In fact, it’s actually a pretty normal thing for laptops to do.
The bad news is that it can be frustrating when your laptop suddenly starts running slower than usual.
There are a few things you can do to try and prevent battery throttling from happening:
| Number one | Make sure you’re using the latest version of macOS. Apple often releases updates that include improvements for managing power consumption. |
| Number two | Avoid using demanding apps whenever possible. |
| Number three | Keep an eye on your Processor Temperature sensor in Activity Monitor (located in Utilities). If this gets too high, it could trigger throttling. |
| Number four | Consider resetting your MacBook’s SMC (System Management Controller). This can help improve overall performance and stability. |
Note
If you’re noticing reduced performance and battery life on your MacBook, you’re experiencing some degree of battery throttling. Luckily, you can do a few things to try and mitigate the effects.
- Keep updated with the latest macOS version.
- Avoid using resource-intensive apps, monitor your processor temperature,
- And reset the SMC if necessary
You can help keep battery throttling under control with a little care and attention!
MacBook Slow After New Battery
If your MacBook is running slowly after you’ve replaced the battery, there are a few possible explanations. It could be that your computer is simply adjusting to the new battery and needs some time to optimize its performance. Additionally, if your old battery was damaged or degraded, that could also be contributing to slower overall performance.

Why Does My Mac Slow down When the Battery is Low?
When your Mac’s battery is low, it may slow down for some reason:
| First reason | The first reason is that your Mac is designed to conserve battery power when running low. This means certain processes and features may be disabled or run less efficiently to save power. |
| Second reason | The voltage supplied to the processor begins to drop as the battery gets lower. This can cause the processor to slow down in order to prevent damage from occurring. If your battery is very low, it may shut down completely in order to preserve its remaining power. |
If you find that your Mac is slowing down when the battery is low, there are a few things you can do to help mitigate the issue.
Close Unnesecerry App
Try closing any unnecessary apps or processes that are running in the background. This will help reduce the amount of power your Mac needs to use and hopefully speed things up a bit.
Disable Energy Settings
If you have any energy-saving settings enabled on your Mac (such as reduced brightness or screen timeout), try disabling them, as they may also contribute to the slowdown.
Plug into an Ac Outlet
If all else fails, plugging into an AC outlet will give your Mac the boost it needs to operate at full speed again.
Why is My Mac Being So Slow All of a Sudden?
There can be several reasons your Mac might be running slowly all of a sudden. Here are some potential causes and solutions to help speed up your Mac again:
Quit Unused Apps
Start quitting any apps you’re not using. Having too many apps open at once can drag down your Mac’s performance. To quit an app, right-click on its icon in the Dock and select “Quit.”
Check for Updates
Check if any updates are available for your Mac and installed apps. Outdated software can sometimes cause slowdown issues. You can update your Mac by going to the App Store and clicking on the Updates tab. For updating individual apps, open up the App Store app, click on the Purchased tab, then find and click on the Update button next to the app you want to update.
Avoid Using Too Many Browser Tabs
Make sure you don’t have too many browser tabs open simultaneously, as this can also use up a lot of memory and processing power. Close any tabs you’re not currently using in your web browser(s).
Having Too Many Files on the Pc
Another possible reason for the slowdown is having too many files and/or folders stored on the Desktop or in other areas of Finder windows.
Consider moving these files into folders or transferring them onto an external hard drive or cloud storage service to free up space on your computer’s internal drive. Doing this can also help improve organization, so it’ll be easier to find what you need later.
Malware Attack
If none of these basic tips seem to help, it could indicate a larger problem, such as malware infection, bad hard drive, insufficient RAM, etc.
