Because you can only run on the new iPhone SIRI?
And the second most frequent question about that is: Why only the new iPhone will be entitled to benefit? Business decision? It's really a wonder. After all, the theory ...
With the launch of the new iOS 5, there were several changes, and a notable change is the optimization of battery life over older versions. And the main optimizations are completely connected only to the device settings.
If you have a problem with the battery, follow some of the following:
1. The network settings can reduce the duration to normalize this, simply reset these settings in the application Settings> General> Reset> Reset Network Settings. Note: This also makes the device forget the passwords of Wi-Fi, forcing you to introduce them again. On the other hand, it also helps those who are not able to have the Personal Access on iPhone 4.
2. If you do not use the new service locations, you can disable them in Settings> Serv. Location and there at the bottom (almost hidden), go to System Services. Turn off the ones you think do not use. If you do not know what, go on trial and error, turn off all and note what changes in the device.
3. Reminders by Location (which only work on iPhone 4) are very interesting, but spend a lot of battery, because they leave the GPS on all the time until the reminder is executed. If you do not need the function, try to avoid it.
4.The Ping is a social network from Apple that nobody uses. And in Brazil the function is totally useless because we do not have an iTunes Store nationwide. So, turn off this feature to prevent the unit from communicating with Apple's servers for nothing. Go to Settings> General> Restrictions> Enable Restrictions> Ping.
5.Se you do not use any accessory that uses the Bluetooth, there's no reason to keep it on. Go to Settings> General> Bluetooth and turn it off.
Apple announced in the media on the date of yesterday (Monday 17th) that his latest product (iPhone 4S), which was released released on 14/10 reached the amount of 4 million units in just the first three days of its release . This means nothing less than double the sales achieved by the iPhone 4 in its launch.
The launch occurred on 14 4S put the iPhone on sale in over seven countries besides the United States.
This news can certainly encourage those who took the test and should or should not buy the iPhone 4S and its result was "no."
