We at PhoneArena take battery life testing seriously: we put all phones that we review through some rigorous testing.
This has allowed us to build a database of all the phones that we have tested in the last few years and on this page you will find all the results summarized in a table.
Here is our process: we make sure that all phones are tested without a SIM card and all conditions are equal as much as possible. One important step to ensuring that is that we set the brightness level of phones to a fixed level of 200 nits using specialized display color meter and professional software. This is a brightness level that ensures comfortable use indoors as the most common use case.
Our first test is the Web browsing battery test over Wi-Fi. It loads up the same set of webpages on all of the phones and then scrolls up and down to simulate real-world use. This is the lightest of our tests as it doesn't put a big load on the processor.
Our second test is the YouTube video streaming battery test. We load up the same video playlist on all of the phones. This is a more intense test that uses more resources, and it provides a valuable and different perspective on battery life that those who watch a lot of video on their phone will appreciate.
Our third test is the 3D Gaming battery test. In this test we load up the same 3D game environment on all of the phones and ensure that all the phones run at the same graphics settings. While the other two tests stress the CPU of a phone, this one also puts a significant load on the GPU and it is particularly useful for gamers.
Our tests are cross-platform, meaning you can compare the results of an iOS device to an Android one. With this in mind, here are the scores for each brand:
The new iPhone 14 series is out in four versions and just as you would expect, the larger 14 Pro Max and 14 Plus models have the highest battery life. But even the smaller models punch way above what you'd expect out of a 6.1-inch form factor. Compare the new iPhone 14 family versus older iPhones in the chart above.
The new Galaxy S23 series is out and they bring a welcome improvement in battery life.
In the above table, you can see how the new Galaxy S23 Ultra and the entire S23 family compares to the previous the Galaxy S22 and the S21 series.

*Some phones have higher than normal scores on the 3D gaming test and the reason for that is that the test was run at 60Hz because of lack of compatibility with the game we use for testing. Most phones however run this game at 120Hz.
Foldable phones are trying to make a dent in the smartphone space, and we have benchmarked the most popular models. Note that we are running our benchmarks on the main screen only.
The Pixel 7 and 7 Pro refine the formula Google introduced last year. They bring the second generation of Google's home-grown Tensor G2 chip. Interestingly, the vanilla Pixel 7 now features a smaller battery than its predecessor, but does this affect actual battery life and how? Take a look at the chart above for our battery test results.
We have most recently tested the OnePlus 10T and the OnePlus 10 Pro, the company's 2022 flagship phones that come with bigger batteries than earlier OnePlus phones, and scored above previous models.
After Huawei was banned from using Android and Google Services, and then after LG exited the market in 2021, Xiaomi has emerged as the quickest growing company, even surpassing Apple as the second largest phone maker and aiming to sell more phones than Samsung in the future.
