I have spent years testing and pushing laptops to their limits to see which laptops actually live up to the battery backup claims. I have tested nearly every configuration of laptops available in the market. And during that time, I saw a drastic change in the battery backup of laptops in both Windows and Apple's lineup. So, anyone who's looking for a new laptop with long battery life, the number of choices now can be overwhelming. In this guide, I shortlisted these five laptops that can give you an all-day battery backup without needing to pick up your charger in between.
How did I select these laptops?
I have tested and reviewed loads of laptops during my career, and during my testing, I tried and pushed them to their limits to verify brand battery backup claims. And while I haven't tested all the laptops from this list, I tested similar configurations from multiple brands, which gave me an idea of which laptops can offer good battery life.
My testing wasn't just based on specs and battery capacity; I checked the in-depth processor configuration to know how much power it draws during different workloads. I also cross-referenced professional benchmarks and user reviews on e-commerce platforms to understand the real-life battery performance of each particular laptop.

Top picks for laptops with long battery life
Apple has always been known for its amazing battery life and performance. After the release of the M1 chip, Apple's claims regarding battery life became even more impressive. This MacBook Air with the M4 chip claims to offer 18 hours of battery life. While brand claims do not always prove to be true, when it comes to Apple, the results usually come pretty close. I am saying this after daily driving an M1-powered MacBook Pro for more than a year; it still offers me a full day of usage on a single charge.
