S7 Edge restarts randomly, doesn't charge, and switches between a dead and full battery randomly.

[Android Central Question]

My phone has been randomly restarting lately and it is very annoying.

I will charge it overnight and in the morning the phone is off and when I turn it on it displays 0 or 1 percent battery and turns off. After a few cycles of doing this it turns on and goes to 100%.

When I plug in my phone, it shoes a lightning bolt in a circle but no percentage, and this screen flashes while plugged in. The symbol stays up for a few seconds after the phone is unplugged as well. I have used 3 different chargers and a wireless charger and it is still completely random whether or not it will charge.

I think maybe it's a problem with the connection between the motherboard and the battery, or maybe the battery logic board. I might open up my phone this weekend to see what I can do.

It sounds more like a bad battery to me.

I replaced my battery 2 months ago. Is it possible for it to go bad that quickly?

Maybe a loose connection between battery and board?

That's what I was thinking. Is there any way to be sure that this is the problem before I open up my phone?

Turn it on and give it a solid bump. If it dies, that would point at loose connection...

The problem is fixed temporarily when I hit the back of the phone. Thank you. I will find the loose connection and fix it this weekend.
