Top 10 Smartphones with the Best Battery Life in 2024

Here are the 10 smartphones with the longest battery life in 2024, as rated by experts.

Over the past year, smartphones have improved in many aspects. They capture better photos, deliver more power—especially for graphically demanding games.

Moreover, more smartphones now come equipped with AI-powered features, enabling advanced processing directly on the device. This not only enhances speed but also strengthens privacy.

However, everything becomes meaningless if your phone can't last long after each charge.

According to experts, longer battery life is the best improvement for smartphones in 2024.

Among the dozens of phones tested in 2024, these are the ones with the longest battery life.

2. Why Is Smartphone Battery Life Improving?

One reason is larger batteries. The iPhone 16 Pro Max has a bigger battery than the iPhone 15 Pro Max. Meanwhile, the Galaxy S24 Ultra comes with a 5,000 mAh battery. As a result, users can get a lot of power from a single large battery cell.

Along with that, the chips inside smartphones are becoming more power-efficient. In the Android segment, the Snapdragon 8 Gen 3 chip powers many flagship devices. This chip is currently found in models like the Galaxy S24 and OnePlus 12.

For iPhones, Apple is reaping the benefits of using a 3-nanometer process for its new A18 chip inside the iPhone 16 models. As silicon shrinks, transistors are placed closer together, enhancing both performance and efficiency.

Similar to the A18 silicon, the new Snapdragon 8 Elite chip—set to be featured in the Asus ROG Phone 9 Pro and the upcoming Galaxy S25 models—also utilizes a 3nm process. Therefore, consumers can expect better battery life from the latest smartphones in 2025, even if their battery sizes do not increase significantly.
