iPhone X Battery Life Results Are In Very Good, But Not Great.
You can leave the charger at home if you're taking your new $999 iPhone X out for the day, but Apple's first OLED-screen phone doesn't last quite as long as the competition.
We run every phone we review through the Tom's Guide Battery Test, which involves continuous web surfing at 150 nits of screen brightness. In this case, that's 54 percent brightness. For our test, we used T-Mobile's network, just as we did with the iPhone 8 and iPhone 8 Plus. (It's also worth noting that we've found that phones tend to last longer on a charge over this network.)
The iPhone X endured for a very good 10 hours and 49 minutes. That runtime beats the iPhone 8's 9:54, as well as the Samsung Galaxy S8's 10:39. Apple's new flagship also blew away the LG V30, which conked out after just 6:30. Apple says that the iPhone X lasts 2 hours longer than the iPhone 7, which hit 9:03, so it almost lives up to that claim.
