Cell phones run on various kinds of batteries depending on the manufacturer, phone size or shape and features. There are basically four types of cell phone batteries: Lithium Polymer, Lithium Ion, Nickel Metal Hydride and Nickel Cadmium.

Lithium Polymer is the most recent type and applies the latest technology in DC power. This type of battery is light in weight and will not explode even if pierced. The battery elements are enclosed in platic pouches and do not have memory defects. They last about 50 times longer than Nickel Metal Hydride batteries.

Lithium Ion is also memory efficient and longer lasting than Nickel Metal Hydride batteries but they are quite lighter. They tend to be expensive and would only fit new models of phones. Most Lithium-ion batteries apply a fast charge technique to quickly charge up your cell phone up to 80% capacity and then slowly bring it up to full power in about two hours.

Nickel Metal Hydride is also memory efficient and lasts longer than the NIM type about 40 times. This type of battery is good for people who need rapid charging and if used with a car charger can be fully charged under 1 hour. The special formula permits the concentration of energy in a single pack – sometimes about twice the power of Nickel Cadmium. This type is preferred by a lot of mobile phone users because it lasts long and is cheap. Again, they are non-toxic and appeals to environmentalists.

Nickel Cadmium are the oldest type and has a lot of memory defects. Another severe disadvantage is that they will have to be totally discharged before you can charge them again otherwise you may irreversibly damage them. Again this type is highly toxic due to the presence of Nickel Cadmium and is gradually being phased out by cell phone manufacturers.

Batteries typically have 300 to 400 charge cycles in their life span. It is so because anytime you charge your battery, the battery loses away some of its potency and thus become diminished in power.

Cell phone batteries can be pretty expensive items if you consider the fact that a Nokia 3310 battery can cost up to $24.95. Here are a few tips to prolong the life of your battery:

Dont allow materials to get stuck on the terminals as that causes the battery to lose contact with the terminals resulting in improper connection.

Keep the batteries in a cool place and allow them to adjust to room temperature before charging as the sharp rise in temperature upon charging can damage them.

The life of your cell phone depends on the potency of your battery. Knowing how they operate and how to care for them can ensure that your cellular device runs and runs well for years.

Short message service (SMS) is a wildly popular feature available on most digital mobile phones. SMS allows users to send short messages to other cell phones. These short messages are called text messages. SMS was invented by a Finnish civil servant named Matti Makkonen. Many people understand what SMS is, but few understand how it actually works.

In SMS, messages are sent with a “store-and-forward” mechanism. The messages are sent to a Short Message Service Center (SMSC), and then relayed to the intended recipient. If the messages do not reach the recipient upon the first attempt, then the SMSC will try again. It is important to understand that SMS delivery is not guaranteed. Many messages cannot be delivered, but the delivery is called “best effort.” The amount of attempts to send a text message varies with the company.

SMS messages are transmitted via SS7 within the standard GSM MAP framework. SMS messages have a certain payload length. The signaling protocol is precisely 140 bytes. In simple terms, SMS messages have very constrained character limits. This is why messages are sent in “txt speak.” Text speak is the practice of shortening words and phrases in order to fit messages into the allowed amount of bandwidth. SMS messages cost different amounts in different countries. In the United States, the average message costs 10 cents.

Text messages do not always have to be sent from mobile phone to mobile phone. AOL Instant Messenger has an option that will send instant messages to a cell phone. Additionally, there is a widget available for Mac OS X Tiger that will allow a user to send text messages to a cell phone from the dashboard. SMS messages can also be utilized to give news alerts. Additionally, SMS messages can be used to give sports updates and statistics. In this way, SMS messages are very versatile.

Technology is constantly evolving. SMS services prove that communication is becoming broader and easier. Technologists predict that SMS service will advance such that the service will be more reliable, and be able to store more data for the purpose of transmission.

The Best Cell Phone Plans Vary According to The Amount Of Calls You Make. Find Out If A Prepaid or Postpaid Plan Is The Right One For You.

Before buying the first prepaid or postpaid plan you see, it’s better to first find out about the different cell phone plans available. The best way to rate exactly what kind of plan you should have is to think about how much you’ll be making calls on your mobile phone. You also need to monitor the time (hour) that you often make calls. This is because most cell phone plans will be limited to ‘anytime’ minutes which mean that you can make limited calls during peak hours.

When looking at cell phone plans, you will also want to consider the amount of coverage you will get. It is important to know whether the prepaid or postpaid plan that you’re signing up for is local, regional or for nationwide coverage. If you do not travel a lot, then it doesn’t matter. But if you do, then it’s important to know what you’re getting into or you could find yourself paying a high price for ‘roaming’ charges. Take note that the cell phone plans with the best values are the ones that include free long distance calls.

A family plan is also an option when shopping for a cell phone plan. It allows you to share your monthly airtime allowance with additional lines. What’s great about postpaid packages like these is that you’ll be able to make free inter-network calling so you won’t have to pay to talk to your family members.

If you are still unsure of which postpaid plan to get, after reviewing the various cell phone plans available, then you might want to consider the prepaid option. The prepaid plan is best if you don’t have a consistent usage every month. What you do is pay a sum of money upfront and you’ll get a certain amount of time/minutes. When you’ve used up all your minutes, you’ll be able to renew it easily. One of the advantages of having a prepaid plan is that you don’t actually have to sign any contracts, although some telco providers may require you to fill in your details for security purposes. If you are unhappy about the prepaid plan at any time, you can terminate the prepaid plan without any hassles!

Don’t Be Fooled When You Shop For New Cell Phones. When You Buy The Latest Mobile Phone, Make Sure It’s Really New.

So you’re thinking of buying the latest mobile phone and your friend says “Why not get a used cell phone? It’s cheaper and just as good!” Now that isn’t quite accurate. It may be true that you can get a fairly new second-hand cell phone at a cheaper price, but the question remains, why would you want to?

In the past, new cell phones used to be much more expensive and it was probably better to get a used mobile phone because of the price. But these days, it’s quite different. New cell phones are more reasonably priced and they come with great cell phone plans that you don’t want to miss out on. Obviously, you won’t be able to enjoy these offers when you buy a used phone.

It’s also true that you can still get some of the latest mobile phones when you buy them second-hand. But why would you want to buy a reconditioned phone? It may look like a new cell phone but you wouldn’t know if it has ever been broken or if any of its parts have been removed or replaced. If you’re shopping for the newest cell phones in the market, then you might as well get a brand new phone. The only reason you might want to get a used phone is because the mobile phone model that you’re interested in is either out-of-date or out of stock.

Honestly, if you’re looking to buy a new cell phone, then you might as well head to the store and get the latest mobile phone on offer. At the very least, you know that it’s new out of the box, and there is a negligible risk of your new cell phone breaking down for no apparent reason.

Of primary concern to all internet users is their actual connection to the internet.A user needs to look at all the factors and weigh the benefits and costs
#

Reliability - is the connection available 24/7, or do you get a busy signal?
#

Speed - at what speeds can a user upload and download files?
#

Costs - what are the setup and monthly costs for the internet connection service?
#

Support - is support available 24/7 and is it free or is there a cost associated with it?
#

Availability - is the desired service available at your location?

Available options with good and bad features include:Local dial up with phone company (local isp) - While this many times is the simplest, often times, they are the most costly and support can be an issue. Speeds are typically the slowest at 26k to 56k connection speeds.

Software file compression- If you only have 26k dialup isp connections available to you or you want to speed up your DSL connections, this is an important option you should take a look at. With this type of software you can increase your internet connection speeds by as much as five times for very little money. Popular software products that accomplish this are ActiveSpeed, PropelAccelerator, Dr. Speed, and SuperSpeeder, Highly recommended solution to increasing your browsing experience.

Local dial up with national firm - This is by far the most popular with companies like AOL, People PC, Juno, EarthLink, and Netzero providing this service to millions of users. These certainly are the most cost effective and provide excellent 24/7 support. With the high speed upgrade options you can approach 112 k speeds. If the company has a local or toll free number available in your area, then this alternative provides the lowest cost isp internet connection.

Broadband - Is a term loosely thrown around that is applied to a DSL, cable, wireless, or satellite internet connections. Technically broadband is a minimum of 1.5Mbs but is used to market products with bandwidth as low as 512k. When you hear the term broadband used, think like "health food", an undefined marketing catch word.

Wireless internet connection - This option is available in limited area's and requires a wireless modem on your computer. Speeds typically are 2Mbps and this is a flexible approach as you do not need to be hardwired or plugged in. Available in many metro area's.
