Late previous year it came to light that Apple has included code in the iOS operating system that throttles the performance of iPhones if the battery is showing signs of wear. In a revised note investor note, obtained by Business Insider, Barclays analyst Mark Moskowitz explained that Apple's iPhone battery replacement program might help cannibalize iPhone sales. The two-week gap between the iOS 11.3 beta 1 and beta 2 gave Apple the chance to address the majority of the problems, and the iOS 11.3 beta 3 update and further releases should just be a series of minor bug fixes and tweaks.
Separately, a memo distributed to Apple stores and authorized retailers last month said that batteries for one model of affected iPhone, Phone 6 Plus, won't be delivered until March or April. Throttling was coded in the software itself to avoid random shutdowns because lithium batteries have a natural degradation process, and to offset that, Apple cut corners in performance.
The move came after a scandal erupted over Apple's practice of slowing down iPhones with older, weaker batteries - in the name of ensuring more reliable performance.
Apple Inc. said it will continue to explore possibly reimbursing customers who bought full-price iPhone batteries, but stopped short of guaranteeing the refund.
Just in case you have one of these phones and you still haven't replaced the battery, Apple has reduced the price from $79 to $29.
Here's where things get a little more complicated. A new battery is supposed to prevent older iPhones from bogging down. However, the only benefit I'd get from a battery replacement right now is increased lifespan since the device isn't being throttled.
With iOS 11.3 installed on your iPhone, there's a new section on the Battery Settings page that details your battery's health.
Having said that, owners of the latest iPhone models can rest easy while at the possible performance reductions caused by old batteries.
