Which? explained that his tests were to charge the brand new battery of independently purchased iPhones, then to measure their lifetime in continuous communication. You can read Apple's test methodology on its website.
Which ones? The discoveries on the battery life of the iPhone XR are particularly interesting. At the time of last year's release, many critics praised the battery life of the device, especially compared to the iPhone XS and iPhone XS Max.
