1 Real-time battery discharging monitoring

Before we deep dive into how to max out the battery life on Surface Pro 4 and Surface Book, we need to know how to track battery discharging in your current configuration. By monitoring the battery discharging we are able to know about:

  • How much power being used in the whole system in real-time.
  • What activities that will use much power to process.
  • Compare power usage when you customize your system configuration.

As my experience, BatteryBar is the best battery monitoring tool out there. It has all features that we need to monitor battery discharging in real-time. Below is all the basic real-time battery information that available:

Real-Time Battery Discharging Monitoring

Above is the battery information captured on Surface Pro 3. Surface Pro 4 has a slightly smaller battery capacity. For more information check out this article How Much Your Surface Battery Capacity in mAh?

As you can see my current Discharge Rate is 3,539 mW or 3.5W and with 82.9% of battery capacity, so it means that with current system configuration and activities my battery life still remains 6 hours and 16 minutes.

Now you got the idea, to get more battery life you will need to minimize discharge rate as possible. Now it’s time to max out your Surface Pro 4 battery life, please check out the following tips:

    What’s your average Discharge Rate?

    • Karry Eyota says:

      For me, If I apply all above tricks, I will get around 3W to 5W discharge rate in average for a light task like note taking. It’s mean that for the full capacity of 42 Wh with a average discharge of 5W, I can get around 8 hours battery life.

  2. Can you put the .reg file to have all the power plan set like yours?

  3. garydx25 says:

    I was looking for something like this. I was disappointed that my Surface has a one-hour battery life, whereas the cheapest Macbook lasts 13 hours. What a joke. Thanks for the article, though.

  4. Jose_49 says:

    For me, what has actually worked is setting up the Max Processor to “40%” or something like that. It will bring down the performance of the Surface down to its knees. But when doing crappy tasks like Notetaking, reading, and surfing the web, they prove to be very useful when multitasking and using non-Edge browsers.

    On the other hand. I have downloaded a script that turns on the High Performance mode when I’m plugged in. The performance increase is considerable vs the predefined Balanced plan.

    Using SP4 + i5 + 8GB RAM

    Using a surface dock 4 with a surface pro 4. Is there any risk related to the battery leaving the surface connected long hours? Is there a technology related with the charger (or dock charger) that allows an intelligent switch (on/off charging) that doesn’t damage the battery when leaving the surface connected long hours?
