Breakthroughs in the tech sector have turned the original bulky hand held devices into sleek mini computers and the batteries that keep these devices going are constantly being improved upon to reliably provide a constant power source.
From Nickel Cadium to Lithium Ion
In the past, battery life was always a hindrance for cell phones as they were powered by Nickel Cadium batteries. These Nickel Cadium (NiCd) batteries were rechargeable but they suffered from memory effect and had to be completely discharged before recharging or they were irreversibly damaged.NiCd batteries also had an exceptionally limited amount of power once charged and ran flat quickly, often needing to be charged several times a day. Aside from their inconvenient life span they also have an added black mark against their use as they contain chemicals that are environmentally unfriendly, and the disposal of the cadium-rich packs has become an increasingly large problem.
Although these NiCd batteries were the cheapest option for cell phones they were most certainly not the best and most modern smart phones are now powered by Lithium Ion (Li-Ion) batteries. These Li-Ion batteries are the most popular form of rechargeable cell phone battery on the market and their longer life span, increased power and lighter weight far surpass the inconvenience of them being the more expensive option to NiCd.
Li-Ion batteries do not retain charge memory and can be charged for short bursts of time whenever required and their only drawback is that they can be damaged by extensive overcharging if left on a battery recharger for too long.

Future developments in battery tech
Lithium Ion batteries are by no mean the ideal cell phone battery and researchers are still working on rechargeable battery technology that offers quicker charging time, longer life span and extended periods of power. Recently an 18 year old student in America won a major science award after she created a tiny device that can recharge a cell phone battery in as little as 30 seconds.This device could potentially change the face of cell phone battery technology and eliminate many of the issues users face when on the go. As this device is yet to hit the market, users will still need to rely on currently available tech to power their phones.
Fortunately, if new batteries are required for devices currently in use they are easy to find as online shops of electrical components wholesalers like RS Components and Premier Farnell carry around the clock stocks. Users can buy RS Components batteries online for powering everything from cell phone to industrial rechargeable batteries.
User's cell phone requirements have changed dramatically from when portable handsets were first released into the market and technology has had to work exceptionally hard to keep up with immense changes that have occurred over a relatively short period of time.
As technology continues to evolve there are almost certain to be new types of rechargeable batteries available and new methods with which to charge them with cell phone battery technology certain to evolve even further.
