A story broke out just a few weeks ago that confirmed a suspicion that many iPhone users have discussed. Apple was slowing down your older iPhone's performance over time, but not for the reasons you'd think. The common misconception about batterygate is that Apple is intentionally throttling your device performance just around the time they release a new iPhone to help boost sales.
While the timing does make a case for this, the real reason behind the performance decrease is the lifespan of older iPhone batteries which like any form of a battery, degrades in performance over time (think of a car, watch or computer). In order to keep your phone from functioning properly and ensure a normal period of battery life, Apple's iOS algorithm has automatically lowered the clock speed over time as the battery begins to decrease in efficiency.
From a consumer standpoint, this sounds outrageous although as someone with a broader knowledge of technology, it frankly makes sense. Where they failed here was not properly disclosing it beforehand and making the sudden discovery of such a practice mixed with misleading headlines an absolute PR nightmare for the Cupertino-based company.
A new page on Apple's website launched yesterday giving a full page of information on batterygate including a description of how batteries age, why they incorporated this throttling method, acknowledging user feedback and addressing their customers' concerns.
One of the ways that Apple is trying to remedy to the consumer outrage of batterygate is by offering a discount of $50 on out-of-warranty iPhone battery replacements for the next 12 months as long as it's on an iPhone 6 or later. This brings the price of such a service from $79 to just $29. Additionally, the company will add an iOS update in the near future that gives better insight as to the health of your internal battery much like they do on a Mac.
