Laptops with Long Battery Life

Laptops their makers rate for 15 hours or more. Maker tests are gentle, so compare battery capacity (Wh) too: it tells you more.

Finding a laptop with long battery life

Every laptop here is rated for 15 hours or more by its maker. Makers test with the screen dimmed and a light task running, so real use with Wi-Fi, video calls and a bright screen is usually shorter, often by a third or more.

To compare fairly, look at battery capacity in watt-hours (Wh) alongside the claim. Between laptops with similar chips and screens, more Wh means longer life. The processor matters as much: Apple M-series, Snapdragon X and Intel Core Ultra 200V chips are especially efficient.

Big, sharp, bright and high-refresh screens use more power. A Full HD screen will usually outlast a 3K OLED screen on the same laptop.

Frequently asked questions

Which laptops have the best battery life?

Laptops with efficient processors (Apple M-series, Snapdragon X, Intel Core Ultra 200V) and large batteries. Sort this page by Biggest battery to compare capacity.

Are battery life claims accurate?

They're best cases from light tests. Expect less in real use, especially with a bright screen, video calls or demanding apps.

What does Wh mean on a laptop battery?

Watt-hours: how much energy the battery holds. It's the fairest way to compare batteries between similar laptops.

How can I make my laptop battery last longer?

Lower the screen brightness, use the battery-saver mode, close apps you're not using and avoid keeping the laptop at 100% charge all the time.
