All of this talk of the Samsung Galaxy Note 7 around and its battery issues. So what exactly is going on then? Is the issue with the phone or is it really the battery? If it is just the battery what is the problem? Many batteries we see everyday to run into no issue yet these Note 7s have bad batteries.What is a battery? A battery is a type of voltage source that is composed of one or more cells that converts chemical energy directly into electrical energy. All batteries use a specific type of chemical reaction called an oxidation-reduction reaction. In this type of reaction, electrons are transferred from one reactant to the other. If the chemicals used in the reaction are separated, it is possible to cause the electrons to travel in the external circuit, creating current. As long as there is an external path for the electrons, the reaction can proceed, and stored chemical energy is converted to electrical current. The image below shows the basic copper-zinc battery. Batteries all follow this basic idea.
I am sure this will lose some of you and so here is a video to help you out a bit.

So the idea here is using chemicals to produce electricity and as for the Note 7, why is this phone such a fire hazard? The problem is the lithium-ion battery which is a common source of power that is used in cellphones, computers, power tools and toys.
Lithium which is the 3rd element on the periodic table is a silver-white metal that can catch fire when exposed to oxygen or water. So how can lithium be used then for batteries? Sounds more dangerous than useful right? Well Sony Corp. apparently made a way to safely use lithium by keeping the lithium ions in a suspension or chemical so that it is not pure lithium.
Properly made batteries have safety measures built into them but faulty batteries with poorly made electric circuitry can end up with fiery results. Bad batteries can be overcharged but good ones will stop charging automatically once they are full. If bad batteries are left plugged in for too long the lithium ions can collect in one spot and be deposited as metallic lithium within the battery. Now remember what happens to lithium when exposed. Heat from the overcharging can cause oxygen bubbles within the gel. You get the picture??? The opposite per say can also be a problem with a bad battery where they can be over-discharged which means they won’t shut off when the power is too low which can also cause a fire.
And there you have it. Be careful when using off name brand batteries or if you happen to still have your Note 7. Also if the battery is not listed as being rechargeable do not try to recharge it. Non-rechargeable, or Primary Batteries, are not designed to be recharged and can cause damage and possibly fires.

Apparently now you have to be careful how you name your device’s wifi hotspot or even your Bluetooth name. Seem an airline has literally stopped a flight due to finding a network named “Samsung Galaxy Note 7_1097” Seriously this flight was canceled due to this. Passengers had to readjust their itineraries.
No Note 7 was found on this plane but no one came forward at first while they went looking for the person who owned this ph0ne with the pilot threating to search everyone’s bag. The person finally owned up to it when the threat to divert the plane from its destination to Wyoming. Mond you this flight was from San Francisco to Boston. I guess this person did not wanna goto Wyoming.
There’s no mention if this person was punished go hey who wants to try to name their phone Galaxy Note 7? You know what if you are one onf the more tech savvy one of us and you flash a Note 7 ported ROM?…..
