Battery


Replacing the battery requires disassembling the iPhone unit and exposing the internal hardware
The iPhone features an internal rechargeable lithium-ion battery.


 Like an iPod, but unlike most other mobile phones, the battery is not user-replaceable.

 The iPhone can be charged when connected to a computer for syncing across the included USB to dock connector cable, similar to charging an iPod. 


Alternatively, a USB to AC adapter (or "wall charger," also included) can be connected to the cable to charge directly from an AC outlet. A number of third-party accessories (car chargers, portable chargers, battery cases, stereo dock chargers, and even solar chargers) are also available.

Apple runs tests on pre production units to determine battery life. Apple's website says that the battery life "is designed to retain up to 80 percent of its original capacity after 400 full charge and discharge cycles", which is comparable to iPod batteries.


The battery life of early models of the iPhone has been criticized by several technology journalists as insufficient and less than Apple's claims.


 This is also reflected by a J. D. Power and Associates customer satisfaction survey, which gave the "battery aspects" of the iPhone 3G its lowest rating of tow out of five stars.


If the battery malfunctions or dies prematurely, the phone can be returned to Apple and replaced for free while still under warranty.


 The warranty lasts one year from purchase and can be extended to two years with Apple Care. The battery replacement service and its pricing was not made known to buyers until the day the product was launched,it is similar to how Apple (and third parties) replace batteries for iPods.




 The Foundation for Taxpayer and Consumer Rights, a consumer advocate group, has sent a complaint to Apple and AT&T over the fee that consumers have to pay to have the battery replaced.


Since July 2007, third-party battery replacement kits have been available at a much lower price than Apple's own battery replacement features.


 These kits often include a small screwdriver and an instruction leaflet, but as with many newer iPod models the battery in the original iPhone has been soldered in.


 Therefore a soldering iron is required to install the new battery. The iPhone 3G uses a different battery fitted with a connector that is easier to replace.


The iPhone two is the first generation to have two cameras. The LED flash for the rear-facing camera (top) and the forward-facing camera (bottom) are both unique to that model.

The original iPhone and iPhone 3G feature a built-in fixed focus 2.0 megapixel camera located on the back for still digital photos.


 It has no optical zoom, flash or auto focus, and does not support video recording (iPhone 3G does support video recording via third-party App available on the App Store), however jail breaking allows users to do so.

 Version two point zero of iPhone OS introduced the capability to embed location data in the pictures, producing geo coded photographs.


                          The iPhone 3GS has a 3.2 megapixel camera, manufactured by Omni Vision, featuring autofocus, auto white balance, and auto macro (up to ten cm). 

It is also capable of capturing 640 × 480 (VGA resolution) video at  thirty frames per second, although compared to higher-end CCD based video cameras it does exhibit the rolling shutter effect.


 The video can then be cropped on the device itself and directly uploaded to YouTube, Mobile Me, or other services.


The iPhone 4 introduced a five point zero megapixel camera (2592 × 1936 pixels), also located on the back, which is equipped with a backside illuminated sensor capable of capturing pictures in low-light conditions, as well as an LED flash capable of staying lit for video recording at seven hundred p resolution, considered high-definition.


 iPhone four is the first iPhone that has the high dynamic range photography feature.

 In addition the iPhone four has a second camera on the front capable of VGA photos and SD video recording.


Regardless of the source, saved recordings may be synced to the host computer, attached to email, or (where supported) sent by MMS.

 Videos may be uploaded to YouTube directly.


The camera on the iPhone four S is capable of shooting eight MP stills and recording ten thousand eighty p videos. The camera can now be accessed directly from the lock screen, and the volume up button as a shutter trigger. The built-in gyroscope is able to stabilize the camera while recording video.



Beta code pulled from iOS 5 suggests that the next feature to be released will allow users to capture a panoramic photo on their iPhone.
On all five model generations, the phone can be configured to bring up the camera app by quickly pressing the home key twice.[92] On all i Phones running iOS five it can also be accessed from the lock screen directly.

Photo browsing

 Photo browsing, web browsing, and music playing support both upright and left or right widescreen orientations.


Unlike the iPad, the iPhone does not rotate the screen when turned upside-down, with the Home button above the screen, unless the running program has been specifically designed to do so

. The 3.0 update added landscape support for still other applications, such as email, and introduced shaking the unit as a form of input.



Furthermore, accelerometer can also be used to control third-party apps, notably games.

 The iPhone 4 also includes a gyroscopic sensor, enhancing its perception of how it is moved.


A software update in January 2008 allowed the 1st-generation iPhone to use cell tower and Wi-Fi network locations trilateration, despite lacking GPS hardware.

 The iPhone 3G, 3GS and 4 employ A-GPS, and the iPhone 3GS and four also have a digital compass. iPhone four S supports GLONASS global positioning system in addition to GPS.
Audio and output


One of two speakers (left) and the microphone (right) surround the dock connector on the base of the original iPhone. If a headset is plugged in, sound is played through it instead.



On the bottom of the iPhone there is a speaker to the left of the dock connector and a microphone to the right.

 There is an additional loudspeaker above the screen that serves as an earpiece during phone calls. The iPhone four includes an additional microphone at the top of the unit for noise cancellation, and switches the placement of the microphone and speaker on the base on the unit—the speaker is on the right.


 Volume controls are located on the left side of all iPhone models and as a slider in the iPod application.
The 3.5 mm TRRS connector for the headphones is located on the top left corner of the device.

The headphone socket on the original iPhone is recessed into the casing, making it incompatible with most headsets without the use of an adapter.

 Subsequent generations eliminated the issue by using a flush-mounted headphone socket.

 Cars equipped with an auxiliary jack allow for hands free use of the iPhone while driving as a substitute for Bluetooth.


While the iPhone is compatible with normal headphones, Apple provides a headset with additional functionality.

 A multi purpose button near the microphone can be used to play or pause music, skip tracks, and answer or end phone calls without touching the iPhone.


 A small # of third-party headsets specifically designed for the iPhone also include the microphone and control button.

 The current headsets also provide volume controls, which are only compatible with more recent models.

 These features are achieved by a fourth ring in the audio jack that carries this extra information.


The built-in Bluetooth two.x+EDR supports wireless earpieces and headphones, which requires the HSP profile.

 Stereo audio was added in the 3.0 update for hardware that supports A2DP.

 While non-sanctioned third-party solutions exist, the iPhone does not officially support the OBEX file transfer protocol.


The lack of these profiles prevents iPhone users from exchanging multimedia files, such as pictures, music and videos, with other blue tooth-enabled cell phones.



Composite or component video at up to five hundred and six i and stereo audio can be output from the dock connector using an adapter sold by Apple.


 iPhone 4 also supports 1024 × 768 VGA output without audio, and HDMI output, with stereo audio, via dock adapters. The iPhone did not support voice recording until the 3.0 software update.

Fast food takeaways are eventually an expensive way to damage your health!

What does 22,000 cases of cancer cost the NHS (us)?
 What is the annual Government budget to truly diagnose and carry out clinical trials on everything we eat?

 How many time and effort is spent from our earliest school days into adulthood to educate us into healthy eating and avoidance of obesity? 

Nutrition should have a far greater spend by the NHS as opposed to trying to treat cancer once it has taken its hold.

 Why is it that only man in this animal kingdom eats and drinks the milk of another animal?

 Think of going dairy free, forget processed supermarket foods with all their additives and get back to basics of vegetable stews, pulses and juicing vegetables.

 Fast food takeaways are eventually an expensive way to damage your health! In most cases obesity is simply down to what you eat, so eat and drink badly and potentially die sooner.

 Do not 'diet' but just simply change your diet.


It frightens me how incorrect the government and NHS Nutritional advice is here.

 Grains (Particularly the Wheat), Polyunsaturated fat and high fructose from sources other than fruit are the main culprits for the terrible rates of heart disease, cancer, diabetes and the countless other diseases of modern age.

 Grains and Polyunsaturated fat have been shown to raise triglycerides, lower HDL, Raise (sd)LDL and (lb)LDL - BAD.

Saturated and Monounsaturated fat have been shown to Lower Triglycerides, lower HDL, Raise (sd)LDL and raise (lb)LDL (lbLDL is benign). 

Oxidation and inflammation are your enemies and the recommended plate above will lead you to it.

 Just because lots of people (Including the NSH and government) say a certain way of eating is right doesn't actually make it the right.



As an independent dietitian, I would like to clarify a number of issues that have been raised in relation to the Eat the plate of good food .

There are a large variety of both wholegrain and white products identified in the yellow starch section and the text promotes and encourages the choice of wholegrain varieties to individuals.


The size of all the sections (including the yellow starch section) is based on scientific evidence developed for the independent Nutrition Task Force.

 This took into account data produced for the Committee on Nutritional Aspects of Cardiovascular Disease and Dietary Reference Values.


The evidence base for low carbohydrate diets (20-40g per day) shows that their long-term health effects (of over 1 year) are unknown in terms of heart, kidney and health of bones.

 Same as it, cancer risk is unknown, especially in those who are obese, so they are not recommended.

Starchy foods of all types are important contributors of protein, iron, calcium and vitamin B complex in particular in our diet.

what is a joke

Eventually, a humor is something spoken, written, or done with joking intention.

 Jokes may have many different ways to express and their different  forms, e.g., a single word or a gesture (considered in a particular context), a question-answer, or a whole short story.

 Infect, the word "joke" has a number of synonyms, including wisecrack, gag, prank, quip, jape and jest.

To achieve their end, jokes may employ irony, sarcasm, word play and other devices.

 Jokes may have a punch line, i.e. an ending to make it humorous or funny.

A practical joke or prank differs from a spoken joke in that the major component of the humor is physical rather than verbal (for example placing salt in the sugar bowl).


Jokes are typically for the entertainment of friends,coworkers and onlookers.

 The desired response is generally laughter; when this does not happen the joke is said to have "fallen flat" or "bombed".

 Furthermore, jokes have other purposes and functions, common to comedy/humor/satire in general.

made of plastic

All buttons except Home were made of plastic on the original iPhone and metal on all later models.

 The touch screen furnishes the remainder of the user interface.

The display responds to three sensors (four on the iPhone 4).

 A proximity sensor deactivates the display lights and touchscreen when the device is brought near the face during a call.

 This is done to save battery power and to prevent inadvertent inputs from the user's face and ears.

 An ambient light sensor adjusts the display brightness which in turn saves battery power which is an effective function for your phone.

 A 3-axis accelero meter senses the orientation of the phone and changes the screen accordingly, allowing the user to an easily switch between portrait and landscape mode.
