In theory, wifi 6 increase battery life.?
Wi-Fi 6s battery usage wont reduce for your typical phone/tablet/laptop and actually would increase if youre using it fully (Wi-Fi 6 is more processing intensive). The claimed benefit in battery usage is when using the TWT (Target Wait Time) facility, which is intended for IoT devices whose radios can spend more of their time sleeping, thus conserving battery usage. Effectively, devices can determine how often they need to wake up to send/receive data from the Wi-fi base.
