IPhone 4s/iphone5 Optimization Guide (save power Province space)

The iphone is good anywhere, the problem is a headache, iphone4s battery capacity is slightly higher than the iPhone4, but iphone4s users are generally reflected in the excessive consumption of electricity too fast. In fact, after installing iOS 5 or iOS 6, users will find that the phone consumes a lot more power than the previous iOS 4, and that the phone's standby power is down, mainly because the new version of iOS's icloud, location-based services and automatic downloads can be expensive. In fact, you can save iOS 6 and iOS 4 as long as you adjust some of the parameters in your phone settings.
1) Positioning service
Usually, the power consumption of mobile phones is high to low, respectively: GPS (positioning) > 3G > Wi-fi > Bluetooth, so the primary power saving settings are positioning service settings.
Go to the iphone "Settings" menu, select "Privacy"-"positioning services", open the bottom of the "system services", turn off the "location-based iad ads" and "Set time zone" and other useless features, only the "Cellular mobile network Search" and "compass calibration" can be. As shown in the following figure.

"Privacy"-"Locate service"-"Find My iphone" and choose "Close".

2) Internet Service
The power-saving settings for 3G and WiFi are mainly to turn off some of iOS's automatic Internet access features.
"Set"-"ICloud", turn off the unused switches, especially the "photo Stream" switch off to prevent the photo from automatically synchronizing the charges.

"Settings"-mail, Contacts, calendar, get new data off.

"Settings"-"Notifications", in addition to the system's own features, as well as the actual need to push the application, the other third-party applications of the push notice, can be closed on.

"Settings"-"General"-"about this machine"-"diagnostics and Dosage", select "Do not send", save the data sent to Apple's traffic.

"Settings"-"Wi-Fi" to turn off "ask if you want to join the network."

"Settings"-"Music", volume balance can be, but the equalizer is best off, compared to the cost of electricity, after testing most of the effect and close almost.


After using the iphone for a while, did you find that the "other" category in the device capacity shown after opening itunes will be more and more space occupied, many users do not know what the space in the end of what documents are occupied, how to clear these documents, in vain to occupy valuable equipment storage space.
The files in "other", most of which are cached or temporary files generated by Third-party applications, have two types of cleanup: manual cleanup and automatic cleanup by software.
Manual cleanup requires finding which applications are the most expensive storage space. In "Settings"-"General"-"dosage", users can see all the applications occupied by the storage space, as shown in the following figure, general video and microblogging applications, long time use will produce a large number of cache files, occupy a lot of space, one after another into these applications, in the settings interface a clear cache or temporary files can be.

Another approach is to clean it up with Third-party software, which now has a software called Phoneclean that can help us clear unused files on iOS devices and free up free space.
Phoneclean This software is developed by a team in Chengdu, China, but it is strange that the software interface and company website is only English version, do not know what is the reason, fortunately, the interface is also very simple, the user's operation will not have any difficulty.
There are four major categories of files that Phoneclean can erase:
1. Temporary files generated by app running;
2. Cached/Offline Files (app-downloaded images, icons, and media files);
3. Cookies and script files (some app access network needs to use the browse and login information file);
4. itunes sync failed or accidentally terminated the remaining "other" files.
The use of the method is also very simple: (Friendship tip: For the sake of safety, recommended before operation with itunes to perform a backup, so that the software mistakenly delete useful data)
Install and start Phoneclean, connect iOS devices and computers with a USB cable, Phoneclean display the used/available space for the device, and let you select the category of files you want to purge and click "Start Scan" to start scanning for files that can be purged on the device. Scan end Display results, select the file you want to erase and click "Start Clean" to clear the junk file.

I tested it on my iphone 4S to clear 500M of storage space, which worked fine.

The iphone 4S Daily maintenance is also more important, first, the iphone does not need to film, film will affect the use of the screen experience, but also do not recommend the shell, will affect the phone cooling, fear of falling words can be added without affecting the heat protection cover.
The iphone uses a built-in lithium battery, which is also cumbersome to replace, so there is a certain amount of knowledge about using the iphone.
1 Lithium batteries do not always wait until the power consumption light to recharge, which will speed up its loss, often the electricity will be recharged to the battery has damage, at any time at random charge will make the battery longevity.
2 Lithium batteries In addition to the fear of low power, but also fear is overheating, especially when the charge, so to avoid the iphone when the hot charging. A more typical example is the next charger to play the game, the game will make the iphone a lot of heat, at this time charging will not be conducive to prolonging battery life.
