I had to lay my Note 2 to rest.
From my research the Note 2 had a lot of issues with corrosion coming through the charging port and frying the phone.
If you live in a humid area, leave it in the bathroom while you shower any issues like this can corrode the phone.
You can press the power button and volume down button at the same time.

OR you can charge your battery on an external charger: Anker used to have one, but can’t find it on Amazon.
