Can you use the internal battery of an iPhone 7 inside an iPhone 8?

I’m guessing because of the similar sizes of the phones, the battery from the 7 can be used for the 8. Is it possible and has anyone tried it? I ask this because it seems that the iPhone 7 has more mAh in its battery and this could make your 8’s battery life even better. Just curious lol

So I did some research on the internet and discovered that they appear to be physically the same size. So if the question is will it fit in the casing, then Yes it can. However, you asked can you use the battery in an iphone 8, which, from what I can tell, the answer to that question is no. First, the connector is completely different. You can see this here: and here: If for some odd reason you found some sort of "adapter", the Watt Hours and the Voltage of each battery are different, which I can imagine the iphone would have a problem with. In conclusion, (Or to save you the reading and research. ;) ) The answer is no.
