In this article we’ll try to present some tips for saving your mobile phone battery. By appliyng these indications you can extend the life of the battery:

- If you have a phone with Wi-Fi connection close when no longer used. Most people forget the connection open after using it.
- The above advice applies if you forget your Bluetooth connection on.
- Always turn off 3G when not in use, use it only when needed.
- Try to use function “vibration” as rare as it uses a lot of energy.
- Turn down the volume keys and ring tones as much when you are in a peaceful environment.
- Reduce as much brightness. The phone uses enough energy to light, especially in the visible touch-screen phones (with large screens).
- Some phones can be programmed as X at Y time to stop lighting keyboard, ex.Samsung E250. Others can be programmed to stop vibration and ring tones in a certain time frame.
- Try to use a background as simple as animated backgrounds (*. Gif) uses more energy.
- Try to load the phone only when it discharged – this advice was particularly true for NiMH batteries, but it seems that newer Li-Ion have a longer life if charge/discharge cycle is observed.
- In the user’s phone, you will find the battery temperature limits functioning normally. Try, if possible, to respect (the phone will not feel good summer looked in the car, but no winter to below 0 degrees)
- If you are a gaming enthusiast phone remember one thing: you will reduce the period of stand-by, so do not be surprised when your battery will take far less than you used. Games use much CPU, along with the LCD are the largest consumers of energy from a phone.

You will review some aspects, namely:

• Mobile phone brand: your purchase is very important for more importance known brands: Nokia, Samsung, LG, HTC, Apple iPhone, Sony Ericsson. Do not be misled by the lesser known brands, which offers many features but will not give a quality product.

Attention! Buy phones only from specialized stores, to give you the invoice and guarantee great attention to this aspect, especially if we decided to invest a considerable amount, try to avoid second-hand phones.

• Defining qualities phone: quality is to be found: stability software, hardware stability, finishing design. You know that for some mobile phones, the battery stays charged longer, about others that have different functions: MP3 player, games, and video camera, or just look like you want.

• Mobile phone battery: stand-by site is an essential criterion in choosing the phone. Usually for a new phone, the battery standby for 5-7 days. Standard cell battery type is Li-ion (lithium), lithium-polymer. We recommend to buy phones with Li-Ion or Li-Polymer

• Mobile phone memory: his memory may be intense or external. As an authorized user, you will definitely look for a phone that have stored a large number of gigabytes, for various other compatible programs, music, store pictures and videos. If your phone does not have enough memory for all applications you want to copy them and use them, there are memory cards compatible with mobile phone type: micro and mini SD, with a capacity of several GB of memory that complements mobile phone.

Tip: Try to buy a phone that has expandable memory card to store more data, especially if you are using media files (photos, music, movies). The phones are included with the purchase card minimum, but specification terminal functions and you can buy cards with higher capacity.

• Mobile accessories: are also very important, and is proportional to sell technical functions and duties of the phone. If mobile phone memory is large enough to support many music files or videos in the package you will find a hands-free, wired or Bluetooth .. Also, you need a data cable and a USB cable or infrared-based one, to transfer files and applications in your computer. Charger is obviously always present.

Tip: For mobile brand known more easily find quality accessories for the other categories unknown, have difficulties in finding compatible accessories.

• Design: competition between companies producing mobile phones is customary. With each model, try increasing compression of features and technology various fields to serve the user in becoming more varied. Already, Japanese companies are about to put the mobile phone market model with which to be able to have access in their own apartment or house, so to replace the traditional key. The phones look more ergonomic design with minimized weight, looking as thin, but at the same time to provide benefits to all criteria for use: large memory, a wide range of colors as, to allow the use of applications similar to the computer (Windows or other operating systems) and many other functions. Gadgets in mobile phones are among the most hunted by consumers.

1. Business class – stylish design, practical, robust
2. Class young people and teenagers – oriented media functions
3. Standard Class – basic functions
4. Fashion Class – dedicated exclusively to the ladies

Tip: When choosing a cell phone, check in advance where you can ask if one of its components do not work while the machine is under warranty, and are also maintenance costs if the phone is no longer is in warranty.

Because phones are becoming more efficient day by day, the damage risk is increasing. If you buy a smartphone (for example an iPhone) you won’t be happy when you’ll see scratches or any other malfunctions such as weak signal, etc.

As long as you will take care of your phone, the chance to fully enjoy it for a long time it’s bigger.

Here are some tips for your phone:

- Do not put your phone in areas with high humidity or dust because these factors can affect the electronic components.

- If your phone has a protection for the screen, do not hesitate to buy and use, especially if you have a touch-screen phone.

If the phone has been dropped in water, follow the next steps:

1. Remove the phone battery

2. In some cases you should put your phone into a bowl of rice for about 24 hours because rice absorbs water very well.

3. If you how to “open” your phone is advisable to proceed in this way so you can dry every component. You should pay a lot attention when you do that, because the pieces can easily broke.

Do not turn on your phone after a contact with liquid. If you do that, the chances that it works again are extremely low.

Do you wonder new iPhone’s SAR value? You will find a detailed answer in our article.

iPhone 4G which was appeared with an interesting story; has been announced officially at the last. Especially, new device has a better performance on its digital camera; also on hardware, battery and other attributes.

It also succeeded to create a different style. While “Super AMOLED?” discussions are going on, more different styled iPhone’s screen made an exact difference against to its opponents with its 800:1 contrast degree.

iPhone seems a stronger device in all fields; but there is another increasing value on a negative point: SAR Value. According to previous generation of iPhone (3G); Apple increased new generation’s SAR value 0.10 scales, totally it reached 0.43 W/kg. Motorola Milestone has 1.38, HTC Evo 4G has 0.96, so iPhone seems very conceivable value. Also, new iPhone reaches 1.17 W/kg SAR value during talking. This ratio was 1.19 W/kg in iPhone 3G S.

We should take care on SAR values for our health.

Electronic parts used in phones have current and voltage limits due to their different resistance characteristics and physical differences. Electronic equipment manufacturers indicate some current values for each piece produced. The excessive or reverse polarity voltage apply to each piece over this value can damage parts. This damage may occur in the form of a physical impairment that can not be noticed by the user generally. For example, tantalum capacity’s, whose parts are small and are preferred because of their high capacity, breakdown occur as a small combustion. However this damage usually can not overflow beyond the covers of the phone. Therefore mobile phone manufacturers select equipments, which are used in their phones, after careful calculations. Manufacturers of these materials select current and voltage limits more than they can endure in their designs to make the human health and safety prior.

Batteries

Mobile phone manufacturers release different types of batteries for every phone model they have created. Used batteries have lots of critical values like charge voltages, currents, temperatures. These values are revelaed with long-time tests and calculations. All phone manufacturers release different batteries developed for original one’s features and proper for charge control software.

Besides, an insurance is stationed in original batteries and protects it from overflow. It is a protection circuit for overflowing and high voltage which prevents overheating especially in lithium-ion batteries. Targeting the user’s safety and satisfaction, producers take all safety measures needed in original spare parts and accessories.

Unauthorized services and non-genuine parts

What we want to warn mobile phone users are, trying to make your mobile phone repaired by unauthorized persons or a mechanic may cause similar situations. Defects that are happenning in phone’s electronics probably occurs because of the opposite directions have been inserted or removed parts non-original parts to be installed instead of original ones. In addition non-original batteries and chargers lead to this type of burns, serious injury or explosive incidents.

Why are the cell phone batteries explodes?

Pre-existing security measures on the phone,even if battery and charger are original, may have been canceled as a result of the repairs by ignorant people.

For example, As a result of unconscious intervention, overcharging battery may give undesired results even if the cell phone works properly.
