After it was revealed in late 2017 that Apple intentionally slows down the performance of older iPhones when their batteries deteriorate, people freaked. There were explanations, recriminations, apologies, lawsuits, and, finally, solutions.But in the wake of that specific controversy, a question arose: Does this happen to Android phones, too?For the most part, the answer seems to be no. While the nature of and Android ecosystem -- with its hundreds of manufacturers, all using different chips and software layers -- makes a comprehensive investigation difficult, there's evidence that suggest Android vendors slowing down older phones because of old batteries isn't a thing.For starters, several major companies, like Samsung and Motorola, declared that they simply don't do it. But there's a more reliable way to check, and that's by going to the same set of data that exposed the iPhone issue: Checking the benchmark scores of older Android phones to see if there are enough of them getting results that are significantly worse than the well-documented scores of a brand-new phone.Primate Labs, the company that created Geekbench, did exactly that."We focused on Samsung simply because they are the largest handset provider on Android, and we viewed this as a litmus test," explains John Poole, author of the original study that provided hard evidence of the iPhone slow-down problem. "We haven't seen any evidence of this widespread performance-limiting problem that has affected the Apple iPhones. It seems to be that this is a problem that is very unique to Apple."Poole joins MashTalk for an extended discussion on the iPhone slowdown problem, and why the issue doesn't appear to exist in that ecosystem. The first clue: Android phones have bigger batteries. But it's not the whole story.Follow John and Geekbench on Twitter.Follow MashTalk on Twitter, too.
