So my sister upgraded her phone and gave me her old Galaxy S7. It has a problem, when left idle, it will drain its battery to 0%, essentially shutting itself down. But I tried watching a 50 minute video on it and it lost 20%. So theoretically, it should have about 4 hrs of video playback capacity.

So my question is, will replacing the battery solve this problem? Or could the problem be something else? Cause I really don't wanna go out and buy a new battery for this, without being certain first.

Thank you all for your responses!

If the phone is working normally, the possible reason is battery or a bug in a management service of the battery. Make e full backup, do a factory reset and see again.

My sister had this problem before she handed this phone to me. I reformatted it as soon as I got it.

So do you think that replacing the battery will really solve this?

Turn Airplane mode on the phone and leave to for a couple of hours. Then check it again.
