Over the festive period I was a back-seat passenger on a longish journey. A talk radio show was keeping me company, the topic of heated discussion, the Apple iPhone battery.
A high school student had recently discovered an issue with his phone and decided to post on Reddit.com giving details of what he had found. He had discovered the decreased performance in his iPhone 6s handset had to do with the phones lithium-ion batteries. He decided to research into why that might be, and found a suggestion online that he replace his battery. When he did, his phone sped up instantly.
His post went viral, eventually leading to Apple to make a public statement, a confession that is said could end up costing the company billions of dollars in class action lawsuits. Apple had issued a statement that made it clear that changes it had made a year ago were indeed slowing down the maximum performance of iPhones with older batteries.
