Which? iPhone battery life comparison test deeply flawed

How would an iPhone with half the battery of competing smartphones ever have won the test, and why didn't Which test a similar device?

How would an iPhone with half the battery of competing smartphones ever have won the test, and why didn’t Which test a similar device?

Which? is getting lots of attention today on strength of its report that claims smaller batteries don’t last as long as larger batteries. That’s the only logical discovery the organization made in a flawed-by-design smartphone battery life test that’s being widely reported.

What the report’s headline doesn’t make clear is that the iPhone 7 in the test has a 4.7-inch display, while all three of the other smartphone models tested are larger (5.1-inches, or more), and equipped with larger batteries. The iPhone could never have won this unequal comparison.

  • iPhone 7: Li-Ion 1960 mAh battery
  • HTC 10: Li-Ion 3000 mAh battery
  • LG G5:  Li-Ion 2800 mAh battery
  • Samsung Galaxy S7: Li-Ion 3000 mAh battery

In other words, the larger the battery the longer the battery life. Which? even admits this, saying, “it should hardly be surprising that one battery nearly half the size of another offers roughly half as much charge.”

It’s easy to imagine the test was set up precisely to deliver the conclusion the magazine chose to run as its headline. After all, if Which had really wanted to run a truly comparative test, it would have tested the larger alternatives against iPhone 7 Plus, a 5.5-inch display device with a Li-Ion 2900 mAh battery. That’s a fair test.

The test it ran is an unfair test, a perfect example of selective testing

Accepting Which? chose not to review a comparative device in a  comparative review, then how can it possibly justify a conclusion that could never have gone in Apple’s direction?

I’m declaring the report to be yet more of the FUD and nonsense that passes for Apple coverage these days. Cheap and tawdry sensationalist clicktivism from an organization I expect much more from. In my opinion, at it’s best the test is flawed, at worst, unethical.

No link provided as none is deserved.

Watching Apple since 1999. I don't say what they should do. I say what they might do. They sometimes do.

    In other news, larger fuel tanks enable longer journeys. Who knew!

    WHICH is a deeply flawed comparison organization that manages to spin their recommendations based on their favorite brands talking points.
    I remember hifi ratings based on colour and loudness, car ratings based on street reactions from passers-by, home insurance ratings on company size, wood stoves rated by size not output, cookers rated by grill position…the list goes on. It’s as if their key audience has zero ability to juggle the multitude of considerations that buyers need to consider when purchasing a product, so they choose the least applicable aspect and construct a story around it. This is a classic example.

    It’s more than an “unfair” test! It’s unethical and completely bogus. Any tech outfit or news out,et reporting its balderdash should be ashamed of itself!
