app to turn off phone when battery low?

I don't know of an app but the warning does make sense, with a non removable Li-ion battery if the voltage gets too low the built in chip won't allow it to charge because the current draw would be so high that there's a chance for over heating and then explosive venting. I've seen a couple of videos and it's not a pretty sight.

That does make sense...no wonder my phone use to blink like 30 times when I plugged it in. Eventually it would start charging....very interesting.

One on occasion, I let the battery get to 5% (overnight), screen warning was explicit - lower and the battery could be ruined. another time I saw warning at 12%. And I had thought that flat linning it before charging was ok, so I was surprises, and so hoped for an app to prevent this.

I have let mine run down to 5% and have not seen a warning other than to connect a charger ant kill any running apps so that the charger can be more efficient.

I contacted Samsung and here is the their answer.

By the way, it took a whole 3 minutes to contact and get an answer via chat. Samsung tech support get an A+++ from me.


Samantha : Hi, thank you for contacting Samsung Technical Support. How may I help you today?
Visitor: There are rumors on the internet that letting the battery run down complete can damage or make it explode , is this correct? I have a Note 2.
Samantha : I am sorry, there are no such reported issues with us. I apologize for the inconvenience. If the battery is down, it will not damage/explode.
Visitor: Thank you very much for your time....
Samantha : You're welcome.

I tried to screen shot the 15 % warning, but of course it was on start screen and phone wouldn't take. Said, paraphrasing, that the battery should be recharged now, or it would for take a full charge... I though about taking it further to read the sterner warning I saw at 3%, but considered that a too bold move.

The s-pen hold button and touch screen method to take screenshot should work on every screen.
