How We Created a Battery Life That Adapts to You with the Intel® Evo™ Platform

Adaptive Battery Life on the Intel® Evo™ Platform:

  • Adaptive battery life automatically balances the performance and system power of every laptop experience, so people don’t have to compromise their most important activities.

  • In a recent study1, people chose a laptop that “can predict and adjust the optimal performance and battery settings” as their #1 desired feature.

  • Intel calls this “adaptive battery life,” and we’re already delivering it with PC manufacturers as part of the Intel® Evo™ platform—verified to deliver all-day battery life in real-world conditions.

What Is Adaptive Battery Life?

For years, people have accepted that better laptop performance means less battery life. This is because battery life was typically measured on a laptop running just one or a few applications in low-power settings. As a result, real-world performance needs often limited the battery life that people could actually expect.

A new class of laptops is changing that—and the key is “adaptive battery life.” Our team created this technology, which automatically adjusts power and performance for concurrent apps, pauses and background tasks—giving people the performance they need at each moment, while saving power whenever possible. This enables Intel® Evo™-verified designs to deliver 9+ hours of battery life on FHD displays2 for incredible PC experiences in real-world conditions.

We know there’s a huge demand: when Intel asked people about new features, 78% selected a laptop that “can predict and adjust the optimal performance and battery settings, so you can get things done quickly or get through the day on a single change.”3 This was the #1 desired feature in both the U.S. and China, for both mainstream and premium laptop users.

Why Adaptive Battery Life Matters

If we think about how people use their laptop every day, it’s clear why adaptive battery life is so popular. Consider a typical day-in-the-life:

Morning: Balancing Power and Performance for Multi-tasking

When you start using your laptop each morning, you probably don’t do just one thing at a time. Instead, you open many different applications, like your email, Slack, Microsoft Office, Google Workspace, multiple browser tabs, videos, and more. Then, you switch back-and-forth between these applications as you work, learn, and get things done. This “concurrent” activity maximizes productivity, but it can also rapidly drain battery.

Adaptive battery life solves this challenge by giving you performance where and when you need it, while saving power when you don’t. For example, it provides a burst of power when you open your web browser, reduces power as you type, provides another burst when you open a new page, then reduces power as you read.

On Intel Evo™-verified designs, this all happens automatically. At every moment for every task, it aims to give the best battery life, while providing for people’s exact needs.

Lunch Break: Saving Power, Waking Instantly

Adaptive battery life also recognizes when you’ve stepped away, whether it’s for lunch, a phone call, or to walk the dog. The laptop shifts to low-energy settings during these idle periods, so you can save battery. When you return from lunch, or come back to your desk, your laptop wakes instantly.

We want to deliver the best PC experience, both with fast responsiveness and long battery life. By closely studying how people use their PCs, we deliver performance when it’s needed and save power when it’s not. That means no more sluggish application launch times, and no more worrying about whether your battery will make it to the end of the day. - Amy Park, Director of Power and Performance Software Engineering, Intel

These kinds of realistic pauses are built into the workflow for the Intel Evo™ verification process. Unlike other battery benchmarks, this process is designed to mirror how people use their laptops, with multiple concurrent apps, common background applications, a live network, cloud accounts, a bright screen, video-conferencing and other real-world conditions.

Afternoon: Ending the “Battery Saver” Compromise

Most importantly, adaptive battery life doesn’t undercut your laptop experience, even for the most demanding applications.

Let’s say you spend the afternoon on a work project that requires extensive calculations in Excel. For this kind of performance-hungry application, adaptive battery life would provide all the power you need, while ensuring efficiency when possible. For example, it would direct power to Excel when it’s open in the front of your screen, then reduce power if you move it to the background.

Adaptive battery life also avoids the compromise of “battery saver mode” at the end of the day. On other laptops, this mode can impact performance, dimming your screen and slowing down your apps. With adaptive battery life, you can keep working, learning, gaming, and more, with the performance for an incredible experience, for the entire day.

Night: Fast-Charging for Whatever’s Next

All these power savings add up. Intel Evo™-verified designs are tested to last for a full day of real-world workflows, so people can buy these laptops with confidence they’ll meet everyday needs.

And once your battery does run down, you can count on fast-charging. Intel Evo™-verified designs deliver up to a four-hour charge in under 30 minutes on systems with FHD displays,4 so they’re ready to stream a movie by the time you’ve finished dinner.

It’s another way our OEM and OSV partners and Intel are designing laptops for people’s needs. Together we’re continuing to improve adaptive battery life and making it available on even more laptops.
