Apple still offers $ 29 Battery Chargers for iPhone SE, 6, 6 Plus, 6s, 6s Plus, 7, 7 Plus, 8, 8 Plus and X. All of these devices are eligible for a discounted battery of $ 29 as per Processor's decline scandal that Apple met earlier this year.
Battery Compensation Expense After Program Shutdown
After December 31
iPhone XS, XS Max, and XR are not eligible for $ 29 replacement batteries when these devices were released well after the battery problem first came to light and is still under warranty.
To start a battery replacement
To start a battery replacement, use Apple's battery support center. You can take your iPhone to an Apple reseller, an Apple Authorized Service Provider, or send it for replacement at an Apple Repair Center.
With both replacement methods, Apple warns that it can take up to five business days, but replacements in stores are often completed faster. Some post-in repairs may take as long as nine days.
Any damage affecting battery replacement, such as a cracked display, must be repaired before replacing the battery for a new one.
Checking the Health of the iPhone Battery
You can check the health of your battery by opening the Settings app, selecting the battery section and selecting "Battery Memory."
The Battery Health option will alert you to the exact maximum capacity of the battery in your iOS device and whether your iPhone can operate at Peak Performance Capability.
If the battery does not work with Peak Performance Capability, you will see a battery replacement recommendation to restore the complete functionality of the device.
Performance Management and Collapse Minimization
Non-functioning iPhones can see random shutdowns due to the fact that a degrading battery is unable to comply with process requirements in peak times.
To prevent the processor shutdowns, Apple introduced a performance management feature that spools the processor on iPhone when the battery can not provide the power needs of the consumer.
Performance management results in slower performance and while the feature can be disabled by following these steps in an iPhone with downgraded battery, the only permanent repair is a new battery.
Apple initially implemented performance management silently in the iOS 10.2.1 update in January 2017 and did not let customers know what happened. The feature was discovered in late 2017, which led to customers who were furious that Apple did not tell them that their devices were lubricated.
It was a major public revolt, which caused Apple to apologize and to deliver a $ 29 replacement program. Apple has offered no-questions-asked $ 29 battery replacement since December 2017.
Performance Management of the Future
All iPhones will eventually face problems with battery corruption due to lithium ion batteries. Although performance management software was first limited to iPhone 6, 6 Plus, 6s, 6s Plus, 7, 7 Plus and SE, Apple in iOS 12.1 added it to iPhone 8, 8 Plus, and X to prevent future shutdown if these devices suffer from failure batteries.
In iPhone 8, 8 Plus, and X, performance management features introduced due to broken "less visible" batteries due to their "more advanced hardware and software design."
Future iPhones, like the iPhone XS, XS Max and XR, will also eventually receive performance management software for battery technology.
