I bought my iPhone, in the start of this year and I always charge it until 80%. The battery doesn’t fall under 20%. The last month when I charge it, it overheats and I don’t know the reason. What can I do? Is a manufacturer problem and if yes has apple to replace my iPhone with a brand new?

If you are seeing a message the phone will continue charging after it cools down, your phone ISN'T overheating. This is a new feature on iPhone and we pretty much all see this message. When you charge an iPhone it generates heat and for the health and longevity of the battery in your phone, this new feature is simply letting you know its doing what it was designed to do.

Note: Most people never see this message on their iPhone as most people plug their phone in to charge when they go to bed and are sleeping and not monitoring the charge cycle at all.
