I got a notification messages on my phone saying "WhatsApp Web is currently active" even when my MacBook is supposed to sleep and not check for messages. Power Nap is not switched on and I have set Do Not Disturb to On when the display is sleeping.
I am concerned about the impact on the battery life of my MacBook. I am not sure if the WhatsApp Web app just prevents the laptop from sleeping, or if the MacBook is in some form of modern standby similar to Power Nap.
I am using the official WhatsApp for desktop application on macOS Mojave:
One option to solve this is to quit the application every time before putting the laptop to sleep. Is there any other workaround to fix this issue?
