If your laptop does not run as long as it used to, it could certainly be a problem if the battery works for years and loses its ability to hold a charge. Or it could be an app with power hunger that consumes more than just a fair amount of battery resources. Before you replace the battery of your laptop (or your entire laptop), you should check the Windows Task Manager to see if any of your apps are causing problems with the battery and not the battery itself. This proven Windows utility has some new tricks (read: columns) up its sleeve.
Advanced Task Manager
WithTask Manager received some attention. It now includes two new and useful columns that show power usage information for the apps you run and background processes.
Wait, let's go back. If you have not used Task Manager yet, there are three easy ways to start the utility:
- Use the keyboard shortcut Ctrl-Shift-Esc .
- Right-click Start button or taskbar, and click Task Manager.
- Search using the search box in the task bar at the bottom left of your screen.
When the Task Manager opens, click the [Prozesse] tab above. You'll see statistics for CPU, memory, disk, network, and GPU usage. On the right you should see two new columns: Energy Consumption and Electricity Consumption Trend . (If these columns are not listed, right-click in the header and select them.)
The "Power Consumption" column tells you if an app is on the low or high side when you get power from your battery. You'll find that this is very similar to CPU and memory usage, but it's still useful to see the app's power consumption estimate in words in Windows 10.
In the Usage Usage Trends column, you must wait a few minutes to see it appear. It shows how much power an app or process has consumed in the last 2 minutes.
For an app that consumes too much power, you can select it in the Task Manager and then press the End Task button in the lower-right corner to close it.
Battery Consumption in Settings
For a longer trendline, see Settings> System> Battery and click . Learn which apps affect the life of your battery . See which apps have used the most battery resources in the past week or in the past 6 or 24 hours.
