I have an iPhone 4s (running IOS 9.3.5). I am going to change the battery next week, do I need to create a backup or anything else before I take it to the shop? If so, please tell me.

Hi
Follow the steps here to prepare your iPhone for service:
Get your iPhone, iPad, or iPod touch ready for service - Apple Support
You should always have an up to date backup before doing any hardware repairs or software updates. Even if a procedure should not ordinarily result in any data loss, things don't always go as they usually should. The whole point of backups is insurance in case something goes wrong or some unintended event occurs.
Does changing a battery erase all the data on iphone
