The same screen gives you an estimate of how long you’ve got left before your laptop or tablet dies (or how much time is left until you’ll reach a full charge). You can also make certain apps exempt from the Battery saver rules and check which apps are the worst offenders when it comes to draining power.

Check Your Power Plan

The old reliable battery-saving method for those that know their way around Microsoft’s operating system, the Windows 10 power plan interface is available through Power & sleep under System in Settings. The lower these screen and sleep times are, the more battery life you’re going to save between charges.

Click or tap Additional power settings to get to the Control Panel power plan interface used by previous versions of Windows. Here it’s possible to set up a bunch of additional variables—like when the hard drive and your peripheral devices go to sleep—and configure several individual power plans that you can switch between as required. Screen brightness can be adjusted from here as well.

Wifi, Bluetooth and Other Settings

Most people with a smartphone know you can turn off wifi and Bluetooth to save some juice, and it’s the same in Windows 10 (this is assuming you don’t need the internet or can get it via a plugged-in cable). The easiest way to switch both off at the same time is via the Airplane mode (or Flight mode) pane under Network & internet in Settings.

The screen brightness is another setting that’s familiar to anyone who’s ever tried to get the last drips of battery life out of a device: In Windows 10 you can find it under Display in the System section of Settings. Turn off the auto-adjust option to prevent Windows from overruling your tweaks.

Update Windows While Charging

You don’t get much control over Windows updates in the latest version of the OS, but based on our testing the process of downloading and installing them has a significant impact on battery life—try leaving your computer on for a few hours (or overnight) before you head out. The previously managed airplane mode can temporarily pause updates if required.

Updates for your peripherals and internal components are worth mentioning too: Check through the websites of the relevant manufacturers to see if any Windows 10 updates are available, as they’ll often improve efficiency, reduce power drain and increase battery life on your Windows 10 device.

Turn Down the Volume

The volume of your laptop (or tablet) has more of an impact on battery life than you might think—pumping out those tunes uses a substantial amount of energy. Try turning down the volume while watching videos and listening to music, or switch to headphones if you can; ideally, mute your device completely.

The master volume control and several of the other settings we’ve mentioned so far can be accessed through the Windows Mobility Center, still present and correct in Windows 10. Just run a search from the taskbar for "mobility center” and click on the first result that appears to bring it up on screen.

Unplug Unnecessary Peripherals

Microsoft itself recommends unplugging any peripherals you aren’t using if you want to save battery power, so ditch those external hard drives, inkjet printers, memory sticks and USB-powered mug warmers until you can get to a charging point. Even having a memory card inserted in your laptop can drain a tiny bit of extra power.

How to Maximize Battery Life on Windows 10

If you’re using an external mouse, for example, you could switch to trackpad or touchscreen input to save some battery juice. Even if your Windows 10 experience suffers as a result, you have the consolation of getting more life from your laptop or tablet while you’re away from a power connection.

While many of us struggle to find a way to discard our dead laptop batteries in an eco-friendly manner, this 11-year-old boy from Maharashtra has found a brilliant way to actually use them.

Meet Vedant Dhiren Thaker, a Grade 6 student of Shantinagar High School, who, unlike other children his age, spends a major part of his day thinking about ways in which he can provide free electricity to the country. In his quest, armed with his love for all things electronic, he has designed and developed a power source which has been made from scratch with a recycled laptop battery.

Vedant is a resident of Mira Road, a Mumbai suburb. Every year during summer and Diwali vacations, he goes to visit his paternal village Tintoi, situated in the Aravalli district of Gujarat. That’s where some of his best friends live. Twice every year, he spends about 15 days with them, and this village is one of most important reasons behind his motivation to invent free power sources. He has witnessed first-hand how children belonging to financially weak families in the village are unable to study at night because there is not electricity.

While he carries kites, clothes, games, and crackers for them during every visit, his bigger plan is to help them study as much as they want to, despite the state of electricity in the village.

"It hurts to see that my friends cannot study after dark. I am also worried about how people in the village cook when there is no electricity. There is a risk of them getting hurt and I want to change that,” says Vedant.

And he has found a way. In January 2014, the battery of his father’s laptop stopped working after a year of use. Vedant wanted to find out what’s inside the battery, so he opened it. A laptop battery pack usually consists of 6 to 8 cylindrical lithium-ion (Li-ion) cells. On breaking into this one, Vedant found that only one of the 6 cells was not working. The rating of one cell was 3.7 volts and 2.2 amperes. All the others were functional but since the cells in this pack were connected in a series and one of them had stopped working, power supply to the others was also restricted. To his father’s surprise, he used one of the remaining functioning cells and installed it in a dysfunctional CFL inverter lamp which then started working perfectly.

When he reached this point, it struck Vedant that there are no charging sources in villages. Hence he thought about one of the best available renewable energy sources – solar energy. His father got him a working solar panel, which he was lucky enough to find at a scrap store. To charge the cells, a direct current output voltage line from the solar panel is plugged in the connector. It hence supplies the output voltage from the solar panel to the cells. Another challenging thought at this point was what if there is a reverse current flow from the battery? To avoid this, Vedant added a diode to the circuit, between the solar panel and the battery, so as to prevent reverse current flow from the battery to the solar panel during the charging process.

And this gives us a power source developed from the use of functional Li-ion cells of a discarded laptop battery pack, with the added feature that the cells can be recharged. All of it done by an 11-year-old!

"Even though such batteries cannot be used anymore for laptops, they still have a lot of residual charge left. This residual power can be used to light up lives of children living in extreme rural areas. The cost will also be small as the battery, which is the heart of this system, comes without any cost,” explains his father.

Ask Vedant how he knows all of this, and he smiles.

"When I was little, I used to ask my father about how everything works. What is this? What is that? He told me everything and I started understanding about electronic products since then,” he says.

His father, Dhiren Thaker, agrees that Vedant has always been an inquisitive kid.

"Ever since he was 5, he showed immense interest in the functioning of electronic items around the house. He used to break some electrical equipment at home and build something new from it. He also dissected his electronic toys part by part. Sometimes, he used to reconstruct them so I wouldn’t scold him,” he remembers.

With them, he constructed many things like an electronic toy boat made from scrap at the age of 7, a sound producing device when he was 6, a remote operated boat at 11, and the latest — a remote operated door unlocking system. He does not take any additional classes or read additional books for this.
