Verizon iPhone 4 Batteries\ Cradles

Cellphones and smartphones are something we take for granted in today's society; nearly everyone has a phone, but few understand how the battery works. Keeping a charge for a few days or a few hours is dependent on the style of battery, the materials it is made from, how many cells it contains, and whether or not it has been misused within its lifetime. Nearly all cellphones available on the market today are lithium-ion batteries that are comprised of separate cells that relate to the storage and output of the battery. Just as in traditional alkaline or lead batteries, the positive anode can react with the negative cathode in order to create a charge that will last depending on the different types of materials used to create the charge. The process of discharging a battery such as one in a modern cellphone sees the positive lithium ions moving from the anode to the cathode and releasing their energy in the process. There is an electrolyte separator between the two charges that controls how fast the battery discharges. If this separator were not in place, then the battery would discharge all at once, creating a mass of heat that would result in an explosion. While we like to think batteries last forever, in reality, lithium-ion batteries can only supply around 300 to 500 charges before they suffer a performance decrease and need to be replaced. When you think of how often we charge our batteries, nearly every day for the modern smartphone, no wonder it becomes necessary to seek a new battery after a year or more of use. Non-replaceable batteries such as those found within the iPhone are a bit tricky, since you cannot simply order a new battery and put it in yourself. The iPhone battery requires you to send your phone in for maintenance, where Apple will replace the battery if it is having problems and so long as it is under product warranty. As mentioned, most lithium-ion batteries like the one contained in the iPhone last about 300 to 500 charges, which is roughly a year or more of use. Since the warranty that covers the iPhone is only a year unless you extend it, if battery performance starts to degrade and the phone is outside of the warranty, Apple will charge a fee of $79 to replace the battery. The service policy for replacing the batteries contained in the iPhone is strict as well. No Verizon iPhone 4 accessories are to be shipped with the phone, otherwise they will not be returned. The Verizon iPhone 4 case and any Verizon iPhone 4 screen protector you have attached to the phone will need to be removed as well, since these are considered accessories. Most people who own an iPhone wonder why Apple chose to include an internal battery in their design, as most cellphones allow you to replace the battery. The answer to this question is quality control. While all batteries on the market today are traditionally lithium-ion batteries, the quality of the battery is determined by several factors. Many people in the market for a replacement battery often purchase a cheap third-party battery in an attempt to save money, but the construction of these batteries can be poor so that the electrolyte separator that controls the discharge speed of the battery can malfunction, causing an explosion. By controlling the battery, Apple can prevent cheap third-party battery replacements from making their way onto the market and possibly giving their device a bad reputation.
