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.

According to the info I found here:https://versus.com/en/samsung-galaxy-s7-… Those batteries are the same and should be interchangable.
