Cell phones have changed the world. A person can remain in "touch" with people around the globe thanks to cell phone technology. Even though cell phone technology is just a few years old, cellular phones have penetrated all corners of the world.
Mobile phones are now available in thousands of models. the phone battery is one of the most important cell phone accessories. The battery life of the mobile phone is one of the key factors users look at when purchasing a new phone. Before buying any smartphone, you must check that mobile phone battery ratings
A battery consists of a cathode, anode, and electrolyte. The cathode is a strip of metal oxide anode metal strip that has a tendency to oxidize, and the electrolyte media conduct in which the anode and cathode are stored. When the anode and the cathode are connected, the anode attracts oxygen atoms thus generating electricity.
Different types of batteries such as alkaline batteries, lead-acid batteries, lithium/manganese battery dioxide, nickel-metal hydride (NiMH), nickel-cadmium (NiCd) batteries, lithium-ion batteries, etc. For mobile phones lithium-ion (Li-Ion) battery many used.
Lithium-ion cell phone battery rechargeable battery. They are much lighter than other batteries because they carry extremely high-density charges and are easier to store than NiMH batteries. They do not suffer from the memory effect. Sony Corporation first introduced lithium-ion batteries in 1991.
Memory effect is a strange phenomenon – if the batteries (typically nickel) repeatedly charged at partial discharge, the battery "forgets" that it has the capacity to let go completely. Gradually the battery loses all ability to fully recharge and should be discarded. Li-Ion batteries also have a low self-discharge rate of approximately 5% compared to other batteries that are generally around 20-30%. However, if mistreated Li-Ion batteries can be dangerous and have a very short life
