How To Test a Free iPhone 4

The new iPhone is out and it's in high demand. If you were not one of the first ones to part with $400 of your hard earned money then why not try to get on the list for a free iPhone 4?

When new phones and electronics come out, the company will sometimes put together a test and earn plan. This means they give you a phone to test and when your testing is complete, you keep the phone. Why would a company do this?

It's really very simple. The company gives you the phone, because they expect you to use it and provide feedback to them. They want to know what you like about it and what you don't like about it. Does the phone make your life better or is it a pain to use? So it's really free?

Sure is. All you have to do is find an offer and sign up for it. If someone tries to charge you for participating in the test and earn plan then you should NOT sign up for it. The free iPhone 4 should really be 100% FREE.

If you haven't heard about the new features on the iPhone 4 then you really should check them out. This phone has the best screen bar none with the highest resolution. That means the screen is eye popping. Another great feature is the app store, which holds many thousands apps to do just about anything you could possibly want to do on a phone. When does the offer end?

You really need to act quickly if you want to be a part of this test and earn plan. Getting your hands on a free iPhone 4 is not that difficult, but the longer you wait the less chance you have. What do you think?

Lithium battery charging

Lithium-ion battery charging current is required by the most appropriate number?

Rechargeable lithium-ion batteries required (GB/T18287 2000 norms): First of all constant current charging, ie a current will, while the battery voltage is gradually increased as the charging process, when the battery terminal voltage to reach 4.2V (4.1V), constant-current charge change for the constant voltage charging,Dell Latitude C640 Battery, Dell 1691P Battery, Dell 75UYF Battery, that is, a certain voltage, current batteries based on the degree of saturation, with the charging process, continue to gradually reduce, when reduced to 0.01C, that the termination charge. (C is the control current of the battery nominal capacity of a representation, such as the battery is a 1000mAh capacity, 1C charge current is 1000mA, attention mA is not Ah, 0.01C is 10mA.) Why do you think the end of 0.01C to recharge your batteries: This is the national standard GB/T18287-2000 under discussion is arrived at. There used to be common to 20mA to end, the Ministry of Posts and Telecommunications is the industry standard YD/T998-1999 such a requirement, that is, no matter how much battery capacity, and stop current is 20mA. GB 0.01C contribute to charge under the fuller, right through the identification of a party manufacturers benefit. In addition, the national standard provides for charging time is not more than 8 hours, that is, even if not yet reached 0.01C, 8 hours to, and also believe that the end of charge. (No problem, the quality of the battery, should be within 8 hours to reach 0.01C, the poor quality of the battery, wait and meaningless) Lithium-ion or lithium polymer rechargeable battery pack for the best rate of 1C, which means that a 1000 mAh of the battery pack is necessary to 1000mA current fast charge to charge such a rate can achieve the shortest charge time, and will not reduce performance and shorten battery life. For the ever-increasing capacity of the battery group, want to achieve this satisfactory charging rates, increase charge current value is inevitable.

2. Lithium-ion battery charging voltage requirements of the most appropriate number?

Lithium-ion battery nominal voltage 3.7V (3.6V), charging cut-off voltage 4.2V Dell Latitude C640 Battery, Dell 1691P Battery, Dell 75UYF Battery,(4.1V, according to the label batteries have a different design) how the difference between battery is 4.1V or 4.2V: consumers do not distinguish between, and This depends on batteries manufacturers product specifications. Some brands of batteries are 4.1V and 4.2V common, such as A & TB (Toshiba), the domestic manufacturers is basically 4.2V. The 4.1V to 4.2V rechargeable batteries for what will happen: Dell Latitude C640 Battery, will increase battery capacity, feels good to use, standby time increases, but will shorten the battery life. For example the original 500, reduced to 300. Similarly, the 4.2V of the overcharge batteries, it will lower its short-lived. Lithium-ion batteries is very delicate. Since the battery inside a protective plate, we can rest assured it: No, because the shield is the cut-off parameter 4.35V (this is good, the bad to 4.4 to 4.5V), protection board is to meet in case, if the per times are too rechargeable, the battery will soon decay.

Is mobile video call turning to internt?

We use the TV mobile phones to watch World Cup and we can also make video calls through our phones. Video call was once regarded as a symbolic function of 3G. But it has turned out that video call is not as widespread as other applications of mobile phone like hi-speed internet service. In other early 3G published countries such as Japan, it seems that the video call is not one of hot functions of 3G, either.

Money and transfer saving
Currently, the video call function of phone has turned to the internet with the appearing of iPhone 4. In the past, the mobile video call is mostly realized by the means of operator's data transfer. In people's mind, the video call is of high cost and data traffic.

The phones which don't support video call were blamed when iPhone appeared. Now iPhone 4 turns the video call into the internet call through Skype software. The change avoids the price and transfer problem properly. There's no comment from apple about it. But it's obviously that video call will have a promising future with WiFi and wirelessgateway. And it will be widely used.

Signal is more stable
Another advantage bought by the change is the stable signal. The 3G signal of different operators is not improved in the most excellent way. The shortage of the broadband also has an influence on the users. At present, the utilization rate of the video call is very low. If the mobile video call is made through the internet, the signal problem of video call is avoided to some extent.

The integrated call of mobile phone, TV and computer
The mobile phone is likely to be connected with TV and computer in the future. On the just completed Singerpore Communic Asia 2010, the CEO of Skype – Josh Silverman said, "the communication will go on everywher. With the software supporting, any computing device can be a communication device and you can make communications anywhere."

He also introduced that Skype had built partnership with some world leading electronic manufactuers. And the Skype software is preassembled in the electronic products. The Skype can provide the users with free internet video and audio call through the desktop and notebook. People can even make video calls with the HD TV in the bedroom.

By the end of next year, eight world leading PC manufacturers will preassemble the Skype software. At present, only Nokia N900 and iPhone can make video calls through the Skype software. It's said that Skype will launch more platforms.

The video call makes the face to face communication between the people in different places. It will be greatly favored by the young separate lovers. You can also communicate with your parents if you are far from home. The video customer service is also realized in many service industries.

The video call can also be a tool of video meeting in some enterprises. Not only the two people video call can be achieved, the long distance video conference can also be realized through the enterprise OA system. In the beginning of this year, it's reported that multiuser video call business is realized in Canada. However, the application is not widely used.

The Samsung Wave boasts a simply gorgeous Super AMOLED display!

The latest Smartphone which Samsung have designed and produced is the new Samsung Wave; the phone offers us a preview of future mobile technology with its 3.3 inch Super AMOLED display, Bada operating system and HD video recorder. Samsung have given there new phone Flash capabilities with its Dolfin mobile web browser and the Wave comes fully equipped with both e-mail and social network integration.

The talented design team at Samsung have given the Wave a traditional and futuristic appearance, if that is possible? Samsung traditionally design there products to look futuristic, the casing around the phone compliments the wonderful Super AMOLED screen perfectly. The display is both bright and very touch sensitive, simple finger commands are performed with the upmost urgency and the jump from screen to screen is managed effortlessly; this is partly down to the Bada operating system. In Korean the word "Bada" means Ocean, the phone certainly does function with an air of fluidity about it, of course the phone doesn't move at rocket speed by its OS alone, it gets its re-enforcements from the whopping 1GHz processor it has under the hood, this monster gives the interface a heightened sensitivity and makes general application use quick and seamless.

The phone has a 5 mega pixel which has an LED flash and auto-focus is capable of snapping those unforgettable moments in a tidy VGA quality, but the real party piece where the camera is concerned is the 720p HD video recorder; it can shoot HD film at 30 frames per second in 1280 x 720 pixel resolutions and it has tons of effects and settings for you to play with. The HD video player has multi codec support for DivX, Real, Xvid, WMV and Mpeg-4; this means you can download full length HD movies to your handset for viewing anywhere.

Samsung have chosen the Dolfin web browser for Wave because it is Flash compatible, it also understands multi touch technology so zooming in and out and scrolling up and down web pages has never been easier on a Samsung device, web pages glow on the beautiful display and text is shown reasonably clearly when zoomed in. The browser is supported by various wireless bands form EDGE/GSM with both 3G and Wi Fi technology thrown in for hyper speed web connectivity. As expected Samsung have added Social Hub to the Wave's software; the Hub collects information from all of your online accounts, E-mail, Instant Messaging and SNS and organises them so contacts can be easily found and contacted, the pre-installed calendar allows you to synchronize events posted on, let's say Facebook or Twitter and organise them into your handset.

The Samsung Wave has a music player which is accompanied by Sound Alive speakers which deliver a 3D sound, the phones memory can be upgraded with the microSD slot, cards up to 32GB can be used so there is enough potential space to fit your tunes, movies and pictures, the phones Bluetooth technology has wireless device connectivity covered while the USB port sorts out you PC synchronization. The Samsung App store allows you to continually add to your collection of apps including apps for social networking, games, news and weather.
