Is the battery of the iPhone SE compatible with the one of the iPhone 5c?

Nope. Besides, even 5S and 5C batteries should not be interchanged. You’d have issues. As for iPhone 5S, many things are interchangeable with the SE except (for sure for now) the battery and the back camera.

No, the SE’s battery comes with a different battery connector

But how can you put the batteries in different iPhones if the connectors don’t match ? I ordered the wrong parts n can’t get them to attach

5c to 5s interchangeable with 100% perfect performance whatever this guys talking about he made up. End of story -CERTIFIED TECHNICIAN

The only iPhones that have had the same battery connector are the 5C and 5S. In the early days it was acceptable to use vice versa batteries for these two but now I do not recommend as you will have issues

I am not certified, and don’t know crap about phones, but I will say that you should listen to the advice of NOT swapping batteries!!! My wife and I have a 5c that her family gave to her after they upgraded and had the battery in the 5c changed since it had died. We took pristine care of that phone until one day it randomly shut off. Sad, we put it in a drawer, and forgot about it. Until I went looking for God knows what one day and saw the iphone bulging out to kingdom come!! Found out it had a 5S battery installed… The ridiculous part is that they say they had Apple replace it, so either their Apple store is stocked with retards, or her family is lying to her because I wanted to switch a broken screen in one of the other phones they let her use when the screen got busted when she dropped it (why we took pristine care of the 5c), and they don’t want me to cause they… think I can’t read instructions and follow them..? I may be a technological moron, but I did manage to take apart two destroyed 2 in 1 tablets and make one whole working one (one shut down randomly, the other had a hammer taken to it= busted screen). I think I’m capable of merely switching parts, obviously! New technology just takes patience as it’s very fragile, and most people don’t have that…
