Finally Words
Every phone we review is tested carefully and also used in real life to see how it performs. We use a special battery test to find out how long a phone can last on a single charge. This test is called the Tom’s Guide Battery Life test.
For this test, we set the screen brightness to 150 nits to keep things fair. Then we run a script that keeps the phone browsing the internet until the battery dies, and we measure how long it lasts. The phones that last the longest make it to our list of best battery life phones. We also remove older phones (over 18 months) to keep the list updated.
