Parallels For Mac Drains Battery

by

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.

I too was experiencing the battery drain on my 13inch rMBP 2015. I have tried most (not all as people are suggesting so many different things) of the solutions offered and the problem still existed. I have spent several hours on the phone with Apple reps running diagnostics, changing power save options and that was a waste of time. All of the following features can be used only when a computer is running on a battery. Parallels Toolbox for Mac Hide non-active apps. Energy Saver hides active (idle) applications. It makes the hidden applications go to the built-in Mac App Nap mode, where they consume very little energy. Pause non-essential processes. Seamless Use Windows side-by-side with macOS (no restarting required) on your MacBook, MacBook Pro, iMac, iMac Pro, Mac mini or Mac Pro. Share files and folders, copy and paste images and text & drag and drop files between Mac and Windows applications. Easy Set-Up Parallels Desktop automatically detects what you need to get started so you are up and going. Parallels Remote Application Server; Parallels Desktop for Mac Business Edition; Parallels Desktop for Mac Pro Edition; Parallels Desktop for Chromebook Enterprise; Parallels Mac Management for SCCM; Parallels Desktop for Mac; Parallels Toolbox for Mac & Windows; Parallels Access. Now my Battery is draining when I simply have Mozilla Firefox 68 running (and not even doing anything). I get probably 4-5 hours when I used to get 10. My Battery Health app says I am operating at 83% and calls that ‘good’.

Disconnect USB devices

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.
