Less than 3 Hours Battery Life - i5

This is unacceptable! I bought this to replace a SP4, i7 16GB RAM because I wanted extended battery life, but I'm not getting it. Less than 3 hours, surfing using Foxfire. Any ideas?

The following is what I see as output from powercfg -energy:

Platform Power Management Capabilities:Supported Sleep States
Sleep states allow the computer to enter low-power modes after a period of inactivity. The S3 sleep state is the default sleep state for Windows platforms. The S3 sleep state consumes only enough power to preserve memory contents and allow the computer to resume working quickly. Very few platforms support the S1 or S2 Sleep states.
S1 Sleep Supported false
S2 Sleep Supported false
S3 Sleep Supported false
S4 Sleep Supported true
Platform Power Management Capabilities:Connected Standby Support
Connected standby allows the computer to enter a low-power mode in which it is always on and connected. If supported, connected standby is used instead of system sleep states.
Connected Standby Supported true
Platform Power Management Capabilities:Adaptive Display Brightness is supported.
This computer enables Windows to automatically control the brightness of the integrated display.

Looks like your Realtek Audio Driver is causing high CPU utilization which was a bug that fixed with a Firmware and Driver update a while ago. Are you missing some updates?

No, all updates have been installed. Guess I will take the tablet to the Microsoft Store and have them check it out.

Not sure why, but today using Chrome I've gotten 6 hours of surfing and am still at 40% battery remaining. Maybe just a one-time glitch.

It possible that an application (like Chrome) didn't release the driver after to playing something...
