In a rigorous bout of battery life testing with a number of handsets from five big smartphone manufacturers, Which? found out that some of the brands fell short of the official numbers provided, and by a not insignificant amount.
Which? tested over 50 mobile phones, with a minimum of six per brand, from Sony, Samsung, Nokia, HTC, and Apple. While Sony sensibly low-balled its talk times, HTC and Apple went the other way. And then carried on going.
Of the nine iPhone models tested, none of them fulfilled the battery life claims from Apple, missing the mark by anywhere from 18 per cent to the worst offender - the iPhone XR - falling short by 51 per cent.
HTC didn't escape unscathed either; with the average talk time of 19.6 hours coming in at six per cent lower than the manufacturers purported 20.5 hours.
"We rigorously test our products and stand behind our battery life claims. With tight integration between hardware and software, iPhone is engineered to intelligently manage power usage to maximise battery life," said an Apple spokesperson in response to the results from Which?. "Our testing methodology reflects that intelligence. Which? haven’t shared their methodology with us so we can’t compare their results to ours."
HTC said pretty much the same thing, explaining that "differences in setup and testing environments may result in some variation to stated talk time figures."
Sony came out of all of this looking pretty good, after testing showed that its phones' talk times were 21 per cent higher than the manufacturer claimed.
While the iPhone XR's battery life is somewhat disappointing, it's still Apple's best-selling phone for the second quarter in a row. You can check out our review of the handset right here.
