For a limited time, Apple has boosted the trade-in values of old iPhones when buying a new iPhone. The higher trade-in prices will apply until June 3.
Based on the model you are exchanging for your new iPhone, you will get an extra $10-$30 credit.
Apple Trade In will temporarily offer more $$$ for your old iPhone
The boosted iPhone trade-in prices will apply across Apple’s online and retail stores for the next two weeks. You will get the increased exchange value regardless of which iPhone you buy; it does not necessarily have to be an iPhone 15.
However, the boosted trade-in values only apply to iPhone SE, iPhone 13, and newer models. So, taking advantage of this offer only makes sense if you plan to buy an iPhone 15.
With the boosted trade-in value, you can get up to $650 for an iPhone 14 Pro Max, up from $630. For the iPhone 14 Pro, Apple will give you $530, an increase of $10 from before. For the iPhone 14 and iPhone 14 Plus, the company has boosted their trade-in values by $10 to $380 and $430.

Look elsewhere if you want to get the most for your old iPhone
Apple periodically runs such promotional offers, where potential customers can get more value for their existing device by upgrading to a new iPhone.
Remember that the trade-in price Apple displays on its page is the maximum price you can get. If your iPhone has physical damage, scratches, or hardware defects, its exchange price will drop further.
Admittedly, Apple won’t give you the most price for your old iPhone. If you want the best price for your old phone, you should look at eBay, Craiglist, or even your carrier instead. Depending on the device’s condition, you can get a couple of hundred dollars more than Apple’s quoted price.
