Regarding the problem that the iPhone4 traffic runs fast

Friend, are you mistaken?

1. About completely closing the application: when exiting a game, just click the home button. But this one game is still working in the background.

So click home to exit the game and return to the home screen, then double-click the home button, this is the bottom of the screen will appear a row of apps, these programs are you have opened, but still working in the background, long press and hold one of the app icons, this is these small icons start to shake, and in the upper right corner of the red "bar" sign appears, click on the red bar, this icon will disappear. That's when you've closed an app entirely. Or you can simply shut down and restart your iPhone, or you can turn off the background operation completely.

However, this only affects the running speed of the machine, and has little to do with the cost of traffic.

2. The mobile phone automatically runs the traffic. Any smartphone has this problem. The iPhone is good, and the Android system is more traffic-running, so you should develop the habit of turning off the "mobile phone card network" at will. The specific steps for iPhone are as follows:

There is a "Cellular Data" option in Settings - General - Network, just turn it off. The cellular data controls the SIM card network, but it does not affect the use of Wi-Fi to access the Internet. If it is closed, it is equivalent to closing the SIM card network, and there will be no loss of SIM traffic.

The next time you want to use your SIM card to surf the Internet, remember to turn on "Cellular Data".

Some of the other items in the network settings may be helpful to you:

3g。Turn on more power hungry and wasted traffic. If you want to open a web page or something fast, then turn it on, and it is recommended to turn it off when you don't usually use it.

Cellular data. Turn on the Internet with a mobile phone card, turn off when you don't want to use the mobile phone card network to access the Internet, after closing the mobile phone card network, the mobile phone can not access the Internet, of course, it will not generate any traffic. This item affects the network connection of the mobile phone card, but does not affect the wireless network connection.

Data roaming, which I never use, is generally turned off.

VPN, off, no.

Wireless network. Turn on when you use wireless and turn off when you don't use it, so as to save power, otherwise it is very power-consuming for the phone to automatically search for wireless signals. When using wireless, it is recommended to turn off cellular data, so that you can surf the Internet for free, and the mobile phone card will not lose data!

It is recommended that you use traffic monitoring software to monitor the monthly usage, and when the traffic is about to run out or you want to use the traffic for other purposes, you can turn off the automatic update of the mobile phone software, and instead synchronize it to the mobile phone through the computer update software, so as to avoid unnecessary traffic generated by updating the software through the mobile terminal.

Close the background program at any time. There are a lot of people who forget to close. Open a lot in the background... Turn off cellular data at your fingertips. I will open it again when I use it. That's how I usually go. It won't cost too much traffic.

The easiest, most practical, and most effective way: turn off cellular data when you are not using the network, and everything else is nonsense, and you will know it after a long time.

The first floor is just too fine

Anyway, you turn off all the useless things, in fact, it won't be used very quickly Anyway, how many megabytes does lz set I am 120m a month, I am a telecom, I didn't buy a 3G card, my classmate, Unicom 3G, the Internet speed is extremely fast, he said that the maximum is more than 800kb per second, I see that the speed of his mobile phone is about the same as wifi, sometimes it is faster, his card in January, 1000m, the traffic seems to be only 36 yuan, I personally think that the machine is used for playing, this province is too restrictive, but the power consumption speed of 3G is fast, although the network speed is fast, the egg traffic is also used quickly, and the electricity problem is the problem lz can buy a power bank to charge on the go.
