APPLE has been accused of overestimating the battery life of its iPhones for up to nine hours.
A controversial Which? Research – already beaten by experts as "meaningless" – suggests that all nine iPhones tested had misleading battery life.
The consumer champion conducted tests to find the "average talk time" for more than 50 smartphones from five top brands.
According to the results, Apple and HTC seemed "both to overestimate the battery life" of their gadgets.
"Apple stated that its batteries lasted between 18% and 51% longer than the Which? Results," the report notes.
But which? has not exactly revealed how it has tested the smartphones – expressing concern among experts.
"Measuring battery life is voodoo magic," CCS Insight, top analyst Ben Wood, told The Sun.
"It really depends on how you use the device, so it's no surprise that there are so many differences between the different tests.
"Without a clear methodology of how Which made its measurements, the results achieved with it are almost meaningless."
According to the Which? report, the new iPhone XR from Apple was the worst offender.
It is claimed that the battery lasted only 16 hours and 32 minutes.
This is in contrast to Apple & # 39; s own claims about a battery life of 25 hours.
HTC is also known as an overrated battery life of 5%, while Nokia, Samsung and Sony are revealed to have underestimated "talk time" with their official figures.
"With cell phones now an essential part of everyday life, we must be able to count on our phones to meet the manufacturer's requirements," said Natalie Hitchins, Which? Head of Home Products and Services.
"There are clear questions here about how long a cell phone's batteries will last.
"So it's important to make sure you find an independent source of reliable information when you buy your next phone."
But Apple has backed up the claims he hit with? because he is too secretive about his testing methods.
Apple publishes a detailed methodology that explains how it tests the battery life – and suggested Which? do the same.
"We rigorously test our products and stand behind our claims about battery life," an Apple spokesperson told The Sun.
"With tight integration between hardware and software, the iPhone is designed to intelligently manage energy consumption to maximize battery life. Our testing methodology reflects that intelligence.
"Which?" Have not shared their methodology with us, so we cannot compare their results with ours. We share our testing methodology that we publish in detail here https://www.apple.com/iphone/battery.html. "
Apple is wrong: battery life testing is an absolute minefield.
Numerous factors can influence the life of the battery, such as the activity of the phone, the brightness of the screen, connection settings (such as WiFi on or off) and even the weather.
We do not know exactly which Which? has performed the tests and cannot guarantee that it is the same method that Apple uses, so take these results with a pinch of salt.
Which? also refused to disclose his method to The Sun – a spokesperson said: "We are testing a wide range of products and our testing is intended to simulate practical use.
"This allows all phones that we test to be compared in an honest and consistent way.
"Although our methodology may be different from that of the manufacturers in this study, we have faith in our powerful and independent testing."
In any case, testing the life of the battery is not necessarily a good measurement to rely on.
It is very difficult to replicate normal phone use with battery life, so they rarely reflect your actual experience with a smartphone.
And even if the claims are "exaggerated", this does not mean that the life of the iPhone battery is also poor.
Apple & # 39; s iPhone XR, for example, has been ranked as the 12th best smartphone since the start of 2018 in battery life on the renowned technical site Tom & # 39; s Guide.
This is considered the best iPhone for the battery life, with which it beats all but one Samsung phones.
And another test of a YouTuber ranked the iPhone XS Max above the best Samsung, Sony and Google phones:
The Sun has also previously written about the impressive battery life of the iPhone XR.
We were also satisfied with the charging performance in our iPhone XR test.
However, all technical companies can probably improve the battery life.
"The battery life is the Achilles heel for all consumer electronics devices," adds expert, speaking to The Sun.
"It's something slower than most other technologies. We've gotten so far that most consumers just need a whole day, and if you're a heavy user, you're carrying a battery anyway."
