Apple recently admitted what many suspected for years when the company announced that its software intentionally slowed down the processors in its iPhones when they age to a certain point.

Apple said they did this because the lithium-ion batteries that iPhones use get more volatile when they age and that this could cause phones to shut off randomly while being used.

That answer still has not satisfied many iPhone users so the company recently announced that it would offer $29 battery replacements for older iPhones for the rest of the year.

So should you get your battery replaced? And how do you do it if so?

Geoffrey A. Fowler, a technology writer for the Washington Post says that the reason Apple has came out with the battery replacement was because many customers have been complaining about battery drainage.

Apple CEO Tim Cook the computer company plans to launch new software iOS so users have to options to choose what they want to be the priority: speed or battery life.

Fowler recommends that you should change your battery now if you have an iPhone 6 or 6s because they have the older version of the battery and it will not last very much longer. It can also speed up the phone’s performance.

A battery transplant on an iPhone 6 it will most likely last you one year or longer, which will help you save thousands of dollars on buying another phone. If your phone has cracks or water damages Apple might refuse to change your battery.

Apple is only replacing batteries for versions of the iPhone older than the  6  like the iPhone 5. They will not be replacing those batteries for that price. Because Apple software isn’t slowing down those products.

If you have an iPhone 6 or 6s you might want to run to Apple as soon as possible to get the new battery. But if you have an iPhone 7 or later you might want to wait until the end of the year so you can maximize your battery life.

Before you just show up at the Apple Store to replace your battery, you should book an appointment. There  are many people going to Apple trying to change their battery so the wait can be days long.

The wait at (which location) is about 11 days long.

The wait in the store for the battery replacement process can take up to  5 hours. Of course, if you are patient enough you can send your iPhone to Apple and they will send it back with a new battery..

Sidebox: How to tell if your iPhone needs a battery replacement? The way you can tell if your iPhone battery needs a replacement is that if you notice that your battery is draining fast then you should go to Apple and replace it.

OK, first, a little about the battery inside the iPhone. According to Apple, the battery “is designed to retain up to 80 percent of its original capacity at 500 complete charge cycles.”

Beyond that, the battery is considered worn and heading toward end-of-life. Some batteries can and do retain more than 80 percent charge after well over 500 recharge cycles.
