  • In just my limited experience with Parallels so far, it looks like it is pretty hard on the battery. The time in the battery meter drops considerably when I have a VM running.
  • If you're a remote worker who needs Windows on Mac wherever you go, Parallels Desktop is a great choice. Yes, virtualizing Windows takes a lot of battery power—but with Parallels Desktop 11's new feature, Travel Mode, you can easily get access to Windows (no matter where you are) without sacrificing too much juice.

If you are experiencing a noticeably high battery loss while your MacBook Pro / Air enters sleep mode, try one of these methods to fix the problem. Ideally, your Mac should lose something between 0 to 1% of battery while sleeping overnight without the charger.

Disconnect USB devices

Parallels today announced the release of Parallels Desktop 16.5 for Mac with full support for M1 Macs. Sometimes there are bugs in iOS that make the battery drain faster, and sometimes we just. I have Parallels Desktop installed with Windows 8 on it. Do you reckon this severely drains my Battery. According to iStatPro, my MacBook Pro has had 44 cycles and the battery health is 97%.

Parallels Inc., a global leader in cross-platform solutions, makes it simple for customers to use and access the applications and files they need on any device or operating system. We help businesses and individuals securely and productively use their favorite devices and preferred technology, whether it's Windows®, Mac®, iOS, AndroidTM, Chromebook, Linux, Raspberry Pi.

MacBooks have this weird ability to keep all USB ports powered while in sleep mode. Even a simple USB mouse nano-receiver will eventually consume a significant amount of battery power, so make sure to disconnect all USB devices when putting your Mac to sleep.

Disable Power Nap

Go to System Preferences > Energy Saver and uncheck the Enable Power Nap while on battery power option.

Disable Bluetooth in sleep mode

Go to System Preferences > Bluetooth > Advanced and deactivate the Allow Bluetooth devices to wake this computer option.

Disable Notifications in sleep mode

Go to System Preferences > Notifications, select the Do not Disturb option from the list and activate the When the display is sleeping option.

Disable networking discovery in sleep mode (NOT recommended)

Just for the sake of completeness, I'm adding this method shown in other blogs, but I don't recommend using it. Some users complained about being unable to revert this change.

Open a Terminal window, type the following command and press enter:

WARNING: This change seems to be non-reversible in certain MacOS versions and could cause network features to permanently stop working. Use with extreme caution as a last resource.

You will be prompted for the administrator password to set this option.

Reset the System Management Controller (SMC)

If none of the previous option fixes the issue, try resetting your SMC. This process will fix all kind of weird hardware issues as well.

If the battery is nonremovable:

  1. Choose Apple menu > Shut Down.
  2. After your Mac shuts down, press Shift-Control-Option on the left side of the built-in keyboard, then press the power button at the same time. Hold these keys and the power button for 10 seconds. If you have a MacBook Pro with Touch ID, the Touch ID button is also the power button.
  3. Release all keys.
  4. Press the power button again to turn on your Mac.

If the battery is removable:

  1. Shut down your Mac.
  2. Remove the battery.
  3. Press and hold the power button for 5 seconds.
  4. Reinstall the battery.
  5. Press the power button again to turn on your Mac.

After applying any or all of the mentioned options, restart your MacBook just to make sure settings are updated. Feel free to leave your comments below if one of these methods fix or doesn't fix the problem with your MacBook.

If you've ever opened your MacBook, MacBook Pro, or MacBook Air after it's been asleep for a while only to discover that its battery has drained since you last used it, you're not alone.

You might think that the battery shouldn't drain at all while your Mac sleeps, but in fact, there are several battery-consuming processes going on in the background. This is perfectly normal and not a fault with the battery.

However, if you've ever wondered why your MacBook runs out of battery so quickly, there are several things you can do to stop it.

How do I stop my Mac's battery from draining?

Here are some of the solutions to fix Mac battery drain while in sleep mode.

1. Unplug USB devices

USB devices that draw power from your Mac may continue to use your Mac power while it's asleep. For example, a USB transceiver for a mouse or external keyboard that remains connected to the device and plugged into your MacBook will drain your battery. The only way to stop this is to unplug the device.

2. Check your Mac for unnecessary background processes

One possible reason for your MacBook battery draining while it sleeps is processes running in the background that you know nothing about. These are often initiated by login items. Login items are applications that get automatically opened when you log in. They can consume a lot of CPU resources and Mac energy.

It's easy to turn login items off:

3. Scan your Mac for malware

Viruses, trojans, adware, and other malware can decrease your battery life. The malicious agents often run parts of software on the background, so it's worth checking your Mac for security threats.

Luckily, it's easy to quickly scan your Mac for malware using an app like CleanMyMac X. This utility can identify different types of malware and remove it straight away.

  1. Download the free version of CleanMyMac X. Install and launch the app.
  2. Select the Malware removal module in the sidebar.
  3. Click Scan.
  4. Hopefully, CleanMyMac will report that it has found nothing and your Mac is free from malware. If not, follow the on-screen instructions to remove the malware it has found.

Detecting malware manually might be tiresome and a long process; CleanMyMac X does a deep scan of your Mac's system to reveal threats that can hide in unexpected places.

You can configure CleanMyMac X to run automatic malware scans.

4. Turn off Power Nap

Power Nap is a feature of macOS that allows your MacBook to continue checking for new emails as well as Calendar and other iCloud updates. However, to do that, it has to connect to iCloud, which means using battery power. So, if you want to reduce or eliminate the drain on the battery while your Mac sleeps, you'll need to turn Power Nap off.

  1. Click the Apple menu and choose System Preferences.
  2. Choose Energy Saver.
  3. Uncheck the box next to 'Enable Power Nap while on battery power.'

5. Disable Bluetooth while your MacBook sleeps

If you use a Bluetooth keyboard or mouse with your MacBook, a setting in System Preferences allows you to tap a key on the keyboard or a button on the mouse to wake it up. However, that means keeping Bluetooth enabled while your Mac sleeps, which will consume energy. So, if you want to prevent battery drain, disable this setting.

  1. Go to System Preferences.
  2. Click Bluetooth.
  3. Press Advanced.
  4. Uncheck the box next to 'Allow Bluetooth devices to wake this computer.'

6. Disable notifications while your Mac sleeps

There is no setting that allows you to turn off notifications while your Mac is asleep, but there is one that disables them while the screen is sleeping. And, obviously, if your Mac is asleep, the screen is also sleeping.

  1. In System Preferences, choose Notifications.
  2. Click on Do Not Disturb at the top of the sidebar on the left.
  3. Check the box next to 'When the display is sleeping.'

7. Reset the System Management Controller (SMC)

If nothing else works, you should try resetting your Mac's SMC. The SMC manages various hardware processes, including how the battery works. While it's something of a last resort, it won't do your Mac any harm and is often recommended by Apple as a fix for problems that can't be fixed with simpler solutions.

How to reset the SMC on MacBooks with a non-removable battery

  1. Turn off your MacBook.
  2. When it is shut down, press Shift+Control+Option (Alt) keys.
  3. While holding down those keys, press the power button (On MacBooks with the Touch Bar, the Touch ID button is the power button).
  4. Hold down the keys and the power button for ten seconds, then release them.
  5. Press the power button again to start up your Mac.
