The most recommended laptops also on a single charge face the problem of keeping Windows running past 12 hours. It can be inconvenient if the charger is not with you and you have to work all day.
Fortunately, Microsoft has been working on making the power management settings on Windows laptop better. Presently, the majority of laptops retain specific settings options designed to increase your battery life.
You can also follow these steps to extend your battery life.
1- Adjust your laptop’s power mode:
1. Click the power mode icon. You should see the pop-up with details about how much battery life you have remaining.
2. Drag the power mode slider to the left. The further to the left you move it, the better your battery life will be — but the slower your PC’s overall performance will be. If you’re only going to be using your laptop for a short time, it makes sense to keep the slider towards the right. But if you need to run on power all day, move it as far to the left as possible.
2- Make your laptop sleep faster:
1. In the Start button search box, type “Sleep.” Click “Power & sleep settings” when it appears in the search results.
2. In the “Screen” section, choose how long your laptop should wait before turning off the screen. You can choose as little as one minute of inactivity.
3. In the “Sleep” section, choose when the laptop should go to sleep. Again, you can pick a value as low as one minute.
3- Turn the screen brightness down:
- In the Start button search box, type “screen brightness” and click “Change brightness level” when you see it appear in the search results. Then, in the display settings, drag the brightness slider as far to the left as you can comfortably go.
- Use the keyboard shortcut to lower screen brightness. Most laptops assign brightness to a Function key – look for symbols on the Function keys indicating higher and lower brightness.
4- Disable Bluetooth and Wi-Fi:
- To temporarily turn off Wi-Fi, click the Wi-Fi icon in the taskbar. You should see the Wi-Fi menu pop up, showing all the available Wi-Fi networks. Click “Wi-Fi” or “Airplane mode.” These will both power down the Wi-Fi radio until you return here and turn it back on.
- To temporarily disable Bluetooth, type “Bluetooth” in the Start button search box and click “Bluetooth and other device settings” when it appears in the search results. Then just slide the switch for Bluetooth to the left to turn it off. You can return here later to turn it back on again.
5- Disable background apps that are power hogs:
1. In the Start button search box, type “Battery.” Click “Battery saver settings” when it appears in the search results.
2. Under the battery percentage remaining, click “See which apps are affecting your battery.”
3. Windows will display apps in order of how much battery they’re using. Click one that’s taking up a lot of power and clear the checkbox labeled “Let Windows decide when this app can run in the background” and then check “Reduce the work the app can do when it’s in the background.”
4. Repeat that for any apps in the list that appear to consume a lot of power.
