Google Assistant’s effect on battery life
It goes to reason that a new feature that takes advantage of always-listening will have an effect on battery life. According to some users, Google Assistant with “Hey Google” detection turned on saw a drop of about 20% within anywhere from 2 to 6 hours. The only thing taking up more power than Google Assistant was the display itself.
Google does mention that this would be a side effect of having voice detection turned on during setup. On my end, I don’t notice a huge difference, with at least 20% of my battery life left at the end of the day. That being said, voice detection isn’t the only way to use Google Assistant.
