Will I ruin my battery if I put it into another waterdamaged phone?
One of my friends dropped her iPhone SE into her sink and half an hour after her phone turned off and she couldn't charge it again. She then put it into a cloth in a week.
After a week she asked me if I could take her phone home with me and find the problem. I think that the problem is the charging port since it's only outputting 0,2 volts. If I take out the charging port and power it via her battery, the phone shows the "battery needs to be charged".
I have an iPhone SE too. Will I ruin my battery if I take it out of my phone and put it into her phone to recover data?
