Part 1. iPhone Battery Replacements and How to Get Them

Battery problems are not uncommon among iPhone users. Your iPhone may have shut down by itself when your battery isn’t drained out yet. Don’t fret. You are not the only one encountering this issue. iPhone makes use of rechargeable lithium-ion batteries, which Apple claims to charge faster and last longer compared to other types of batteries.

However, wear and tear can affect their performance and lifespan. There are other factors too.

Apple has received flak, not only once but twice, for its batteries on iPhones. In late 2016, it was found that a small number of iPhone 6S have batteries that decline faster than normal batteries. This is caused by a battery component being exposed to controlled ambient air longer than usual.

In December 2017, Apple released a statement saying that their updates have been slowing down the performance of old iPhones to prevent unexpected shutdowns. This is in relation to an update on iOS 10.2.1, which is intended to manage the maximum performance of iPhone 6, iPhone 6 Plus, iPhone 6s, iPhone 6s Plus, and iPhone SE. This is to make up for the declining battery life in chemically-aged batteries.


To address the issue, Apple has launched the iPhone battery replacement program in January 2018. This will continue through December of the same year. Apple promises that once the battery has been replaced, the iPhone’s performance will be back to normal. Under the program, owners of iPhone SE, 6, 6 Plus, 6S, 6S Plus, 7, 7 Plus, 8, 8 Plus and X are eligible to receive free battery replacement as long as the device is covered by warranty or AppleCare+. Users can avail of a discounted price of $29 if the replacement was initiated after the warranty period.

Prior to the iPhone battery replacement, Apple will test your iPhone if you indeed have a battery issue or not. If there is a certain problem on your device that would prevent Apple from replacing your battery, this should be addressed first. There may be a cost for the repair. Just head to an Apple Store to have your iPhone problem fixed.
