If you own an iPhone 7, there’s a good chance that you have a casemate. This is a type of case that helps protect your phone from scratches and other damage. To remove the casemate from your iPhone 7, first remove the battery. Then, use a screwdriver to pry the case off of the phone. Be careful not to damage the phone in doing so. Once the casemate is off of your iPhone 7, use a hairdryer to heat up the adhesive on top of the case. This will cause it to pop off of the phone and release the battery and other components inside.
