Now you will have to search for two screws which are placed near the iPhone’s slot. You will have to remove those screws, but you have to be really careful when you do this. There are big chances that you could damage some components of the phone and you surely don’t want to do this.

This is the time when you have to lift your phone so that you can see the back.  You can slide the  cover of the phone with your fingers. You have to be very careful here because this cover will slide just a few millimeters. Please remember that you don’t have to force it to slide mode because you could create other problems for you.

The battery will die faster if you leave it on all the time.

Optimize the Cell Phone Batteries

Maybe you don’t know this, but the first time when you charge the phone, you should leave it charge completely.  Let’s clarify this: you will not disconnect the charger when the phone tells you that the battery is full. No, you will disconnect the charger after a set amount of time.  What does this mean? Well, we are talking here about 12 or 16 hours.

The temperature of the battery is also extremely important.  You should keep your phone in cool areas to protect the battery. Some people actually place the battery of their cell phones in the refrigerator. They do this overnight and with the batteries placed in zip lock bags. Don’t forget that cold areas can increase the lifetime of a battery.

The battery time reduces considerably up to 11 h in 2G and 6 h and 30 minutes in 3G. I guess that’s really not a very good thing if we look at the iPhone 4 battery that in stand by resists up to 300 hours in GSM band and 300 hours in 3G ; when you are talking, it resists 14 hours in GSM and 7 hours in 3G. That half and hour can be really important for a business man that is about to sign a contract, a young teenager that has a fight with his girlfriend or a mother that tries to convince her son of not doing something bad.

The operating principle is quite simple. When discharging ,the lithium ions move from the negative electrode to the positive electrode. When charging, the direction of movement is reversed. It is chemistry inside a shell.

Why Do Cell Phone Batteries Have Three Contacts

The construction of the Li-Ion batteries consists in three parts: the anode, the cathode and the electrolyte. The anode is made of carbon, the cathode is usually a metal oxide and the electrolyte is a lithium salt in an organic solvent.

There is another type of batteries, the NiCd batteries, cheaper than the Li-Ion, but Li-Ion  type can operate in a wider range of temperature.

A usual question from cell phone batteries users is “Why do the cell phone batteries have three contacts?”.  First of all, a battery may have three or four contacts. To find out the answer you can access the following link .  If you are not in the mood for internet surfing and you want a straight simple answer, there it is. The cell phone batteries have three contacts because one of the contacts is the positive reference, one contact is the negative reference and the third contact is for a thermistor. The majority of the cell phones  have a thermistor in the battery pack. It is used to prevent the battery from charging when the temperature is below 0° C. For batteries with four contacts, the fourth contact is probably used for a memory device.

You can tell if the third contact is for the thermistor by measuring the resistance between the negative reference and the presumably contact from the thermistor. The resistance should vary with the temperature if it is the proper contact.

Cell phones have a problem: the battery. Some cell phones have very good batteries but others not really. If the battery doesn’t last at least 4 days you can say that it’s useless, because we all talk to the phone at least 2-3 hours a day. So, what is cell phone good for if you have to keep it permanently on charging? So, small cell phone small battery. Does this mean the battery will last less than a bigger cell phone? The answer to this question is no. And that is because the manufacturers try to make better batteries in smaller sizes. Like laptops, PCs, flash drives USB stick smaller isn’t necessary worse. It can be small on the outside but large on the inside. When we want to buy a cell phone we are interested in its capacity to store information, its size or its case.

On a cell phone we listen to radio, we listen to music on the mp3 player, we even can watch movies if the phone is high tech. So, we have thousands of colors, we listen to music, we play games and all of these consume the battery. It is very important for a cell phone to have a battery that can last very long. It is possible for a new generation phone to be less helpful than an older one. But I believe that in very few cases this happens because the industry of cell phones would have much to lose if they weren’t paying attention to these details.

Nowadays for some people having a cell phone is crucial, and I am referring here to businessmen. They have two even three cell phones.For them, communication is very important and they can’t afford a dead cell phone. They have to be in touch always with many people, so if the battery of one phone is dead, they can use the other one. If you leave home and you have three cell phones you must bring with you three chargers thing that is a little disturbing.

Another problem with cell phone is the charger. At some point, everyone has a problem with it. Every phone has a different charger that is why in case it breaks it’s hard to find quickly a replacement. You can borrow one if you have a friend with the same type of cell phone as yours, but generally everyone has different models. So, all you can do is buy another one. But what happens if your phone is too old? What if you can’t find any charger at any cell phone store? Does this mean you have throw out your phone? Maybe so. The point is the companies have come up with an idea that will help everyone: universal charger. From now on, all producers of cell phones are obligated to make a universal charger that will work on any type of cell phone. This way, if your charger breaks and you can’t find one at any store you just buy a universal one and your problem is solved.
