The tests were conducted by Tom’s Guide and the results are surprising: from the data collected during these tests, the new iPhone recorded worse results than the iPhone X.
In these tests, iPhone XS and iPhone XS Max were used in continuous web browsing (via LTE connection) until the batteries have run out completely. The displays were set to 150 nits of brightness, with TrueTone settings and automatic brightness turned off.
The iPhone XS Max remained on for 10 hours 38 minutes, above the industry average of 9 hours and 48 minutes, while the iPhone XS went off at 9 hours and 41 minutes. The iPhone X, on the other hand, reached 10 hours and 49 minutes in the same test.
