Can you use a battery from an s9 in an s7

The touch screen on my s9 stopped working and i cant afford a new phone so my friend gave me their s7 to use until i am able to get something else. The issue is that it wont hold a charge and will drop from 40, 50,, even 60 percent down to 0 in a matter of seconds even if i havent really used it. I need my phone for work and with my job i am not always able to have it plugged in so i was wondering if i could take the battery out of my s9 and put it in my s7 until a replacement arrives.
