On cellphones, the battery is equivalent to the heart in the human body. As much as mobile phones have evolved, batteries are still not developed.
At present, the cellphone is only powered by Lithium Ion (Li-Ion) or by lithium-ion battery suppliers. The first is the type of battery that is most widely used for cellphones. Compared to NiCd and NiMH batteries, Li-Ion batteries are lighter and they don’t suffer from “memory effects”.

Older cellphones use Nickel Cadmium (NiCd) or Nickel Metal Hydride (NiMH) batteries which both have weaknesses. Among them are “memory effects” and heavy metals used in the production process. “Memory effect” is the depression of the cellphone battery voltage.
In other words, if you don’t really take out the battery before filling it, after a few cycles the battery remembers the low level at which it was charged and since that time it functions like it runs out. NiCd batteries suffer more than NiMh because of “memory effects”.
It seems that the future in the cellphone industry consists of Lithium Polymer batteries. Li-Poly batteries have a larger life cycle than Li-Ion and they also have an energy density of 20% higher.
Even though the price is somewhat more expensive than Li-Ion, Lithium Polymer batteries seem to be the next choice of cellphone manufacturers, and with the increase in production costs, it will eventually drop.…
