If you’re like most iPhone owners, you probably change the battery color at least once a year. But if you want to keep your phone looking new for longer, there are a few tricks you can use.

So if your phone’s battery is yellow, changing it to white will make it look newer. To change the battery color on an iPhone 6 or 6S, open the Settings app and go to General -> About -> Battery.
