Driving the conspiracy that Apple intentionally slows its devices-a scheme commonly referred to as planned or forced obsolescence-is a recent benchmarking test that found older Apple devices had a cap placed on their processing power, which has led some to use the test as evidence Apple is hindering its own products.
If Apple is going to drop the performance of a smartphone because of poor battery life, it should replace an iPhone's battery at no charge. The battery is backed by a one-year warranty. Lithium-ion batteries become less capable of supplying peak current demands when in cold conditions, have a low battery charge or as they age over time, which can result in the device unexpectedly shutting down to protect its electronic components.
The company said it added the fix a year ago to prevent shut downs on iPhone 6, 6s and SE models, then added it to the iPhone 7 with plans for more devices in the future. He specifically notes the iPhone 6s and 7 who received upgrades to iOS 10.2.1 and 11.2 respectively that introduced the slower speeds. We can't speak as to which option users would choose if given a choice, but we agree with Geekbench's John Poole and The Verge when they say that this is more likely to cause users to believe it is time to replace their slow phone. It seems all of this was a deliberate move on Apple's part, and that the company will continue to include these features in future devices as well.
To mitigate this issue and similar ones, particularly when batteries get old and begin to drain more quickly, Apple has started to algorithmically alter how the phone uses power. They found that the CPU was running at only 600 MHz, but after replacing the battery, it returned to the factory speed of 1400 MHz.
Apple deliberately limits the performance of its iPhones when its battery deteriorates beyond a certain level to encourage users to upgrade, it has been claimed.
So if you think your phone isn't performing at its best, or you want to refresh an old phone, try replacing its battery. That absolutely makes the phone more useable - it apparently helps stop random shutdowns too, which are a major pain. A battery swap from Apple costs $79. Some researchers say your phone doesn't slow down at all and it's just you thinking things are getting worse, but as discovered by a developer at Geekbench, you may actually be right. They'll then see a further deterioration in performance when Apple throttles the processor.
In other words, rather than just get a new battery, some iPhone users might feel compelled to get a new device.
