Thinkvantage Power Manager is designed specifically for thinkpads and optimised for the batteries that ship with Thinkpads. It is more accurate and have better charging method.

While, windows one is more generic built with no particular system in mind.

As such Lenovo's one is better, as you can select the different charging plan which is not allowed by windows.

Use Power Manager's advanced pane, and configure your profile manually.

Set CPU speed to low or lowest on battery power if you can tolerate it. Enable CPU Deeper Sleep for both AC and battery.
Set brightness as low as you can tolerate on battery power.

Decrease the wireless adapter's performance on battery power by choosing Maximum Power Savings or Moderate Power Savings.

Turn off the Bluetooth radio using Fn+F5 when you don't need it.
