Modern cell phones change rapidly so current models are constantly being superseded for a newer, improved version; improvements in technology mean there is very little that cannot be added to these devices. Buyers need help with this problem so they make the correct choice and not end up with a phone they don't need; below are some facts every user should know before upgrading.

With the advancements in battery technology, batteries last much longer than they did when they were first invented but waiting until the last possible moment to recharge is not a good idea. If you do not want to replace your cell phone battery early then you must not continue leaving the recharge cycle until the last minute.

One easy way to extend the life of a cell phone battery is to turn off the back light or reduce the brightness just so you can see what you need to on the screen. When the phone is operational, it is constantly searching for a signal which is ok when there is good signal strength but if this is lost, it still tries to find a signal using more power and draining the cell phone battery in the process; the same way that long conversations do. The longer you talk the more power you will use; limit your usage of cell phone games or Internet browsing as these are high users of battery power even though you're not actually talking.

One way that young people get caught out is with the many things they can now download onto their phones which are often chargeable even if this is not made clear at the time of purchase. For parents buying a phone for their child, most companies will now allow them to disable this download function so only the mother or father has control over it via a password feature that the child cannot override.

Before you make a decision on a cell phone it is worth considering how many minutes you will use per month and whether it will be worth arranging for a pay-per use agreement or a pay monthly contract which could be for twelve or twenty four months. Only you will know how often you make calls and how long they are on average but the pay-per use agreement is probably not going to be the most cost effective if you are someone who uses the phone a great deal. Consider the features you want, as long-term plans often have more features for less money or even as a bonus, at no charge; so ask if all your features, such as caller ID, will work when roaming.

Some plans do not include roaming charges which is something to consider if you travel a great deal as it could dramatically increase the cost. Steer clear of a contract that does not supply the phone with an insurance warranty as you could be liable for any costs if it were stolen or inadvertently damaged.

Many companies now offer phones online and do not have physical stores; these will often have late model cell phones that you may find it hard to find accessories for so ensure you trust the supplier before you buy.
