I purchased your 5s battery and the install was going well until I tried plugging new battery into phone. The new battery size is the same as my iPhone model A1533 battery ,but the plug on the cable is larger than existing (female end) on my phone. Any suggestion would be appreciated. Or did I purchase the wrong battery? David Jefferson CDJefferson10@gmail.com

The iPhone 5 battery connector is a lot larger than the 5S so it would look like you ordered or received the wrong model battery.
