Controversy began in December, over iOS being programmed to artificially limit the processing capabilities of older iPhones when their batteries were deemed insufficiently powerful to keep up with maximum performance.
As of now, anyone with an iPhone 6 or newer device should be able to merely ask for a battery replacement and receive one for $29/£25, according to an internal memo that was obtained by iGeneration (and confirmed as authentic by MacRumors). Apple conceded it hadn't communicated the issue sufficiently well, and promised a more affordable way to replace the battery inside handsets dating back to the iPhone 6.
Apple apologized for secretly slowing down older iPhones, a move it said was necessary to avoid unexpected shutdowns related to battery fatigue. Whether or not this is the true reason for slowing down older models is up in the air, but many customers are up in arms due to the lack of transparency regarding the process.
It would seem the latter has been the option of a trio of plaintiffs in the USA who have filed lawsuits against Apple essentially claiming Tim Cook's crew failed to inform them about the processor throttling and that such enforced slowdowns were unethical and deceptive. Apple lowered the battery replacement cost from $79 to $29, even for out-of-warranty devices.
Apple is already replacing iPhone batteries for $29. The company also said it is planning to release a battery diagnostics tool within a future iOS update, so users can see for themselves when the cell may need replacing.
Many users could have smartphones operating at below 80% capacity, as the iPhone 6 debuted in September 2014, while the iPhone 6S arrived a year later. Some customers even report that Apple is offering retroactive refunds to those who paid full price for a battery replacement within the last 30 days.
But it claimed to be doing this as a means to prevent processors from demanding too much power from older Lithium-ion battery packs, which degrade over time and struggle to deliver the peak currents and battery life they could when new.
On the website, either make an appointment at your local Apple Store's Genius Bar, or another authorized service provider. There, Apple may be able to do a same-day fix or offer you a loaner phone.
