Phones with best battery life in 2025: Independent test results
Looking for a phone that won't let you down when it comes to battery life? We've got you covered.
At PhoneArena, we are independently testing the battery life of each smartphone we review.
So which are the phones with the best battery life? Below, you can find the top performers, along with key details about their endurance.
Notice: How you use your phone affects how long its battery lasts. Some phones are great for watching videos, but might run out of power quickly if you play games. Others are good for checking emails and websites, but might not last long if you do a lot of other things. Consider how you'll use your phone before you choose one.

The Asus ROG Phone 9 Pro is a powerhouse designed specifically for gamers. It boasts top-tier specifications and features that cater to the demands of demanding mobile games.
But gaming requires a battery that can last for a long time and power optimization to help it do that, and the ROG Phone 9 Pro delivers with a massive, 5,800 mAh battery.
The ROG Phone 9 Pro's efficient power management and advanced cooling system help to optimize battery life, allowing for extended gaming sessions without frequent charging.

It is mostly universally agreed upon that Apple could have done better with the iPhone 16 series this year. That said, one area where we saw a substantial upgrade was with the battery life, with the iPhone 16 Pro Max marking the best battery life on an iPhone we have ever seen.
The iPhone 16 Pro Max has a slightly larger battery than its predecessor. While the exact capacity isn't officially disclosed, teardowns suggest it's around 4,685mAh. This is the biggest battery ever used in an iPhone.
It offers excellent battery life. Based on our tests, it can last around 22 hours of web browsing, 10 hours of video streaming, and 12 hours of gaming. This is largely due to the combination of a larger battery, efficient A18 Pro chip, and optimized iOS software.

The Asus Zenfone 11 Ultra is a feature-packed flagship smartphone designed to cater to the needs of content creators and mobile enthusiasts. It offers powerful performance and most importantly for this list—a long-lasting battery.
While the Zenfone 11 Ultra may be larger than its predecessors, its increased size has a significant benefit: a substantial 5,500mAh battery. Although not as large as the 6,000mAh cells found in ROG phones, the Zenfone 11 Ultra still delivers exceptional battery life.
In real-world usage, the phone can easily last for a full day, even under heavy workloads. With moderate usage, you can expect up to 1.5 to 2 days on a single charge.

Samsung did not increase the battery capacity with its new Ultra model, but thanks to the Snapdragon 8 Elite chip the Galaxy S25 Ultra received 20 more minutes of estimated battery life compared to its predecessor, or 8 hours in total. The difference mainly came during our Browsing and Gaming battery tests.

At fifth place we have another one of Samsung's new flagship phones, the Galaxy S25 Plus. The case here is exactly the same as with the S25 Ultra—the battery capacity is unchanged but the more power-efficient processor means longer battery life compared to the previous generation.
A total of 7 hours and 23 minutes of estimated battery life according to our battery testing. The phone lasted us around a day and a half with regular use.
Affordable phones with the best battery life:
Among all affordable phones we’ve tested so far in 2025, the Motorola Moto G (2025) holds the crown for battery life. It beats the competition with an outstanding score of 8 hours and 15 minutes, especially shining in web browsing with over 22 hours of runtime.
In second place is the Google Pixel 9a, which is just behind with 8 hours and 11 minutes of estimated battery life and an even longer video playback time of nearly 11 hours. Right behind it sits the Nothing Phone (3a), which leads the pack in video endurance with 11 hours and 6 minutes, despite having a slightly lower overall estimate of 7 hours and 38 minutes.
Also worth highlighting is the OnePlus 13R, which pushes a massive 6000 mAh battery to deliver nearly 19 hours of web browsing, although its gaming endurance lags a bit behind the top contenders.

How we measure battery life
The PhoneArena Battery Score provides a comprehensive overview of a smartphone's battery performance, including:
- Overall Battery Score: A single number that represents the device's overall battery efficiency.
- Battery Life Estimate: A projected estimate of how long the battery will last under typical usage conditions.
- Detailed Test Results: Breakdown of performance in web browsing, video streaming, and 3D gaming.
- Charging Speed: Information on both wired and wireless charging speeds.
- Rank Comparison: How the device compares to other smartphones tested.
How the PhoneArena Battery Score is Calculated
Our battery tests are conducted under controlled conditions to ensure accurate and consistent results. We evaluate performance in three key areas:
- Web Browsing: A script cycles through a set of webpages, simulating typical browsing behavior.
- Video Streaming: Full-screen video is streamed to assess battery life during media consumption.
- 3D Gaming: A demanding 3D game is played to test the battery's ability to handle intensive tasks.
All tests are performed at a standardized brightness level (determined via a specialized light meter) and over a Wi-Fi connection.
This allows us to provide a straightforward assessment of battery performance, detailed test results and charging information offer a complete picture, as well as rankings and average scores that allow for easy comparison with other devices.
