IPhone4 use of the official recommendations of the tutorial IPhone4 power saving Tips

Still because the iphone's standby use time is too short and distressed? In fact, as long as we follow some common sense problems in daily life, we can effectively extend your iphone battery time and life! The first is to read two terms: Battery time and battery life battery time represents the iphone's battery when it is running out of power and before it must be recharged. Battery life represents the iphone's battery performance failure, the full use time before it must be replaced. Avoid placing the iphone in direct sunlight or exposure to a car that can seriously reduce battery performance. Check usage status Statistics How do you know how long your iphone battery can usually hold? You can view the usage stats for your iphone by setting--general--time spent. After the last full charge of the use of time will see two functions: Use time: The iphone since the last full charge, in the wake up state, and in the use of the total time of operation. (What is the wake state?) is when you are talking, texting, listening to songs, surfing the internet and so on a series of operations, that is, wake-up state. Standby time: The total boot time of the iphone since the last full charge, including the use time and sleep standby time. Lock your iphone When you do not need to use the iphone, you should lock the iphone, click the Boot button, and, of course, by setting the automatic lock screen to complete the operation, you can easily make your iphone after a period of time after the automatic shutdown. By setting-general-auto lock, and then arbitrarily adjust a time interval, such as a minute. Often use the iphone to maintain the lithium battery in a timely manner, so that the electrons in the battery remain liquid and do so at least once a month. (What is the charge cycle?) is to fill the battery and then run out of the battery completely. Upgrade to the latest software to ensure that the iphone is in the latest software version, as Apple engineers may have developed the latest way to optimize battery performance. Upgrade the iphone's software version to the latest by using the latest version of itunes. Connect the iphone to your computer via a data line and click to check the update to see if there is a new iphone version available. Click on the update to download the installation. Optimizing iphone Setup features some habitual problems that may shorten the iphone's battery time, and do the following to help you extend the battery's use time. (For iPhone3.0 and later only) reduced GPS/A-GPS positioning services: Enabling applications with positioning services, such as maps, can significantly shorten battery usage times. To turn off the positioning service, set the shutdown by setting the location service and, if necessary, turn on the positioning service function only if necessary. Turn off push notifications: Some applications use a push notification service to Apple, the dataReminder service. For example, we often use the Instant messaging software QQ, microblogging, etc., may affect the use of battery time. To turn off push notifications, turn them off by setting--notifications. Reduce the frequency of automatic synchronization updates: Some applications (such as email) will be automatically synchronized every time after the update operation, the higher the frequency of synchronization updates, the consumption of electricity will naturally be faster. At this point, we can get new data manually by setting-mail, Address Book, calendar-to get the new data and gently manually. If you only want to increase the time for automatic synchronization, you can change to hourly. This setting applies to all applications that do not support push services. Turn off push mail: If you are using a push email account with Microsoft Exchange, turn off push mail if you don't need it. Get new data by setting-mail, Address Book, calendar-and then push off. After that, the message is not received by the phone as soon as it arrives, but is received based on the push settings of your iphone. Turn off Wi-Fi: When you do not need to use Wi-Fi, you can turn it off to save power. Set the--wi-fi, and then set Wi-Fi off. Develop good habits, do it anytime, don't bother. Turn off Bluetooth: If you rarely use a Bluetooth headset kit, you can turn Bluetooth off to conserve power. Turn Bluetooth off by setting-Universal-Bluetooth. Turn off 3G: Using 3G cellular networks can improve the speed of loading data, but it also shortens battery usage, especially in areas where 3G signal coverage is bad. To turn off 3G, set it to shutdown by setting-Universal-network-enabled 3G. In places with GSM network coverage, you can still use the edge or GPRS cellular data network by receiving and dialing calls. Use flight mode for poor or no signal coverage: Since the iphone has been trying to stay connected to the cellular network, it is consuming more power in areas with poor or no signal coverage. In this case, it may be possible to open the flight mode to extend the use of the iphone battery, of course, the phone will temporarily unable to receive or call. Open by setting-flight mode. Adjust screen brightness: Adjusting the screen brightness is another way to extend the battery's time. Adjust the screen brightness of the iphone by setting-brightness and sliding left. In addition, turning on the automatic brightness adjustment allows the screen to automatically adjust with ambient brightness through a light sensor. Turn off Equalizer: When playing songs, The equalizer also reduces battery usage time. Close by setting the--ipod--music-equalizer. Please note that if you have already added the equalizer directly to the song in itunes, you must turn off the flat on the iphone to achieve the effect of turning off the equalizer.
