Several problems with the iPhone 4

1.When the iPhone's 3G is turned on, the mobile phone is always in a state of networking, and if the 3G signal is weak, the built-in 3G module of the iPhone4 will increase the power to enhance the mobile phone signal, which causes the mobile phone battery to lose power faster in places with poor signal.

2.The traffic consumed by push is not large,If it's just a push service,It's estimated that it's only a few MB at most,In addition, there is a phenomenon of running traffic on iPhone,Not necessarily caused by push,It's not clear。

It will not be automatically turned off, when out of the area covered by the wifi signal, it will continue to search for surrounding wifi hotspots, and the power consumption at this time is very large, if the wifi has been turned on often for a day, there will not be much power.

4.iPhone automatically saves all connected WiFi hotspots, as long as you enter its coverage area, as long as you turn on WiFi, you can connect it, you don't need to manually connect again.

5.I'm also more concerned about this, so I just bought it back and bought a protective case, which can strengthen the signal and protect it, which is pretty good.

6.The iPhone comes with GPS is not cold start, unlike the navigation device on the car, in addition, the iPhone self-guided Google map has an offset, it is recommended to buy professional navigation software such as AutoNavi, or use piracy after jailbreaking.

Give you the most perfect iPhone question answer.

1.You only connect when you need data, but if you have IP4 multi-threaded, that's not a problem.

2.I don't know how much traffic is, and no one has calculated it.

The wifi is connected by default, you have connected once, it will still connect to this hotspot by default next time you go to this place, so you can try it at home and the company once, and then the company at home will use the connection you specified.

5.You decide for yourself whether to fall or not, according to the quality of the iPhone, it is easy to break if you deliberately fall, but if you accidentally slip out of your pocket, it should be fine, my generation of machines has been run over by a taxi, isn't it okay?

It depends on the software you are using, not IP4.

1. Connect to the Internet when you need to get data.

2. Very little, basically none, if you don't receive push data.

4. Yes, after connecting to the wifi, enter the wifi settings, there is an automatic join in the wifi network you are currently connected to, as long as you open it, it will be automatically connected as soon as you enter the wifi network, my situation is the same as you, the unit and the home are automatically connected.

5,3gs has fallen, the screen is not broken, the IP4 screen is glass, as long as the screen is not touched by a hard object, it generally can't be broken, you still buy a protective case, it's better than nothing.

6. It seems that the GPS of the IP does not have a cold start, if you feel that the navigation software is slow to connect, first use Google Map to locate it once, and then open the navigation software. Also, don't try to pinpoint the location indoors, the GPS chip of the phone can't reach that level.

1. The mobile phone can be in 3G mode, it can be compatible with 2G, and generally 3G is automatically turned on.

2. There seems to be no specific numerical concept of how much traffic can be run in a day.

3. The wifi is automatically turned on and can be set by yourself.

4. Yes, the computer is general, the first time it is set up, there is a storage memory function.

5. The concept of falling is not very clear, I fell once, the screen is a little bulging, but I haven't bought a coat yet, and there are a little scratches on the side.

6. Let's go down to Gaode by yourself, it's very easy to use.
