Does your beloved iPhone slows down after a new one is launched?
Well, the company is the culprit. So why would they do that, one might ask.
Apple in a statement said,
Lithium-ion batteries become less capable of supplying peak current demands when in cold conditions, [when they] 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.
Last year, we released a feature for iPhone 6, iPhone 6s and iPhone SE to smooth out the instantaneous peaks only when needed to prevent the device from unexpectedly shutting during these conditions.
We’ve now extended that feature to iPhone 7 with iOS 11.2 and plan to add support for other products in the future.
Our goal is to deliver the best experience for customers.
BUT
But why keep it a secret for so long? It's like decieving the customers of the knowledge about the expiry date of a food item.
Or could it have been a marketing tactic all along? So that, right when a new iPhone is launched, the old ones become slow and people flock to buy the new one. A few years down the road, the new one sufferers from the same date and the circle continues.
Here's why it might be true.
According to a research conducted at Harvard, the number of searches for the keyword "iPhone slow" increased by quite an amount right before a new iPhone release was around the corner.
But a similar research for Samsung phones didn't give the same results.
Conclusion:
Although this is not evidence to state that it "is" a marketing tactic by Apple but there is definitely something fishy going on.
The fact about batteries not giving optimum performance after sometime is true as after cycles of charging and discharging they wear out.
