This range accounts for various factors like device model, usage patterns, and ambient noise levels.

CPU Usage Statistics

The CPU usage related to hotword detection is usually minimal. The system strives to keep the CPU utilization below 5% when the device is idle and actively listening. During active use of the hotword feature, the CPU utilization may spike temporarily, but the system aims to minimize this impact.

Real-world Case Study

Consider a user who actively uses “Hey Google” several times a day for various tasks. If this user is on a phone with a 4000mAh battery, the daily battery drain attributable to the hotword feature might be around 5-10%, which translates to approximately 200-400mAh.

Example of Battery Drain Illustration

Let’s imagine two users, Alex and Ben, both with phones of similar specifications and a 4000mAh battery. Alex actively uses the “Hey Google” hotword frequently throughout the day, while Ben rarely uses it.

Alex’s Usage: Alex uses “Hey Google” about 20 times a day for various tasks, including setting reminders, making calls, and searching for information. Due to the constant listening and processing, Alex’s phone experiences a 8% daily battery drain attributable to the hotword feature, consuming about 320mAh of battery capacity.
Ben’s Usage: Ben only uses “Hey Google” once or twice a day. As a result, Ben’s phone shows a minimal battery drain of around 2%, corresponding to about 80mAh per day.

This example highlights how the frequency of hotword usage significantly affects battery consumption.

It is important to understand that these data points are approximations and can vary based on various factors. Users can often monitor battery usage in their phone’s settings to get a more accurate assessment for their specific device and usage patterns.
