A reader, Tom, writes, “Apple's updates slowed down iPhones to save battery life. I was wondering if I do replace the battery in my iPhone 6, will my phone still run slower? I did notice significantly slower operation after the update.”
Late last year, Apple ran into some trouble when some long-held suspicions about what happens to older phones when the company rolls out new phones and updates, proved true. Apple said it has reduced speeds on older phones with new iOS updates in order to keep them from crashing when their batteries wear down. It then reduced the price of replacing an old iPhone’s battery to $29 on iPhone 6 and 7 models.
For now, you might still see some slowdown on an older phone, even if the battery is replaced with a new one. But Apple has promised a future software upgrade that will allow users of older phones to turn off the software feature causing that intentional slowdown. It should be out sometime this spring. The deadline to get that discounted phone battery replacement is the end of 2018.
