An update on the previous article in which we talked about updates that are not known to many in the iPhone 4S that have started GPS system GLONASSNow, we are talking about a new feature and a new update which is Bluetooth 4

Perhaps the most critical criticism that he directs to the iPhone, especially from the Arabs, is the Bluetooth, as the Bluetooth technology in the iPhone to communicate with other devices only and does not support Apple in its system to send or receive files through it, and the reasons are many that we talked about previously, but the most important one is that the iPhone system does not have a manager Files And sending files via Bluetooth has become uncommon with the spread of social networks and other media sharing methods.

But in terms of the iPhone's support for Bluetooth technology, it is an essential part of the components of the iPhone, iPod and iPad, and Apple is working to keep pace with the development in technologies in general, including bluetooth, so Apple made an unprecedented technological breakthrough as the previous phones iPhone 4 and iPhone 3GS They had Bluetooth version 2.1 and all very modern phones such as Samsung Galaxy S2 and others contain Bluetooth 3, but the iPhone 4s was supported in an unprecedented way and before all, and it became the first phone to be issued with Bluetooth 4 - before the release of the Motorola Droid Razr phone - but what is the difference Between Bluetooth 2.1, Bluetooth 3 and Bluetooth 4

Bluetooth 2 was released in 2004 and then followed by 2.1 in 2007. In theory, the transmission speed can reach 3 megabytes per second. It is known as the traditional Bluetooth which is available in most devices currently sold.

Bluetooth 3 was released in 2009 and theoretically it can reach a transmission speed of 24 megabytes per second, meaning that it is characterized by 8 times the speed of the previous version and is known as high-speed Bluetooth and is found in some very modern devices and depends mainly on high speed

Bluetooth 4 was released in 2010 and is called low-energy bluetooth, as it is much lower in energy consumption and the decrease may reach 90% of the energy. As you know that Apple's traditional enemy is the battery of its devices, so Apple supplied its devices with this version, which is characterized by low energy use and also characterized by speed The high characteristic of the Bluetooth 3 predecessor, that is, it combines traditional bluetooth and high-speed bluetooth in addition to being low energy consumption

Also, the Bluetooth 4 technology enables the device to connect to more than one device at the same time and receive data from them, meaning that the phone can connect to a heart device and also a telephone headset, meaning that it serves beautifully in the medical field, and let's be honest together, the iPhone 4s will not benefit from all the advantages The current Bluetooth 4 because the technology is still very modern and has not spread yet, but Apple basically wants to open a wonderful new field, for example, you may be a doctor and follow the condition of a patient, so you connect your iPhone device to the patient’s heart device and receive its graph continuously because the extent of Bluetooth 4 maybe It is less than the previous one and it is 50 meters, but it is an actual and not theoretical field - precedent of 100 meters in theory and 10 meters in practice - you can leave the bluetooth in the active mode always because the bluetooth in the new version consumes approximately one-tenth of the previous consumption, which enables us to use it beautifully for several tasks As mentioned a little while ago.

It is worth noting that Apple has registered a wonderful new patent, which is about switching off Bluetooth automatically at the end of the task entrusted to it, and to clarify this, and what Apple seeks is that we sometimes drive the car and receive calls on the bluetooth speaker and then we close the call and get to work and take out the phone after two hours For example, we remember that we did not turn off the bluetooth and we find that the battery has expired. Apple’s innovation seeks to leave the bluetooth in the active mode, then it automatically shuts off and opens automatically when a new call comes in and closes at the end - this is a new patent and is not a feature of the new iPhone - perhaps We see it on the iPhone 5 next year.

The bottom line is that Apple seeks to kill two birds with one stone

  • First, open the field for innovation by using the new features of Bluetooth and relying on letting it work permanently
  • Secondly, saving the phone battery, which is the cause of the sadness of every iPhone user
But despite that, the iPhone 4S battery has not improved significantly, perhaps because there is another load of the processor and new additions, and perhaps the situation would have been worse if Apple had not used Bluetooth 4 technology in the iPhone 4S.
