Strange, when I uploaded this subject the notice came back

 Gateway not working try again later.

But here it is ,  properly uploaded!

Now I'm anxiously awaiting your solutions to my problem

 

 

 

 

Is the only accessible help was to do a restart! 

IT didn't help

My old Samsung started behaving exactly as you describe a few weeks ago. Wasn't the battery, wasn't the charger, wasn't a dirty port, did a factory reset. Still dropped to zero and wouldn't charge. Went to Samsung and a mall phone stand. Both said it was the phone. Nothing to be done. As this was my cheap backup phone, I went to AIS and got another. For the same price as the Samsung bought five years ago, got something called an Oppo. Not as good as my other top end Samsung but good enough.

There is not one specific answer. It could be one of several possible problem.

Just go to a service center and let them check it.

 

Last week the Samsung table from my gf didn't charge. They told me if it wasn't on warranty then they would charge 250B (about) to check what the problem is. I think that is cheap and much better than guessing.

I don't know about other companies but I guess they won't charge a lot more than that.

Sound quite likely that either the charger, unlikely, battery, probable, or charging port, possible, is dead. Most good third party repairers can both test and replace the battery and charging port if needed
