How do I return my iPhone 18 Pro Max?
The new iPhone 18 Pro Max has the biggest battery of any iPhone. Due to transport regulations for phones with larger lithium batteries, it requires a different returns process. For now, if you need to return your phone, take it to any Currys store with proof of purchase. Your legal and statutory rights are not affected.
