Where's my traffic? Calculate will know!

Xiao Bian yesterday leave a message, someone is my mobile phone about the consumption of traffic to what extent, Xiao Bian today to answer.

001

A look at the flow of consumption

002

video:

Tencent standard definition as an example, a 40-minute TV episode, video 150MB ~ 220MB, if it is live streaming traffic will increase, while high-definition video Xiaobian not recommended for use on mobile phones (in advance Wi-Fi environment to download, watch as much as possible Turn off the option for mobile apps to use mobile data).

voice:

WeChat, for example, is about 50KB to 80KB in 1 minute. This consumption is not really high, and it can be made so that there will not be any problems.

Text message:

We still use WeChat for example: 1 message is less than 1 KB. In most cases, communication handshake and sending messages themselves will not consume more than 1 KB.

According to the standard one Chinese character = 2 English letters = 2 bytes to calculate, 1KB can accommodate 512 Chinese characters, but because the encoding problem (UTF-16 encoding, UTF-8, etc.) will cause a Chinese character to occupy 4 bytes, also It is 1KB that can accommodate 256 characters.

So, why did SMS disappear? Understand?

image:

Or use WeChat to say things, GIF moving pictures, ordinary pictures, depending on the quality of the send (the original picture size will be MB, compressed picture KB units), which is generally a few hundred KB.

Online games:

The game consumes us as an example of the king's glory. 5V5 consumes 8MB to 15MB of traffic for about an hour. Of course, there is no way to accurately measure this.

Who is the largest consumer of traffic

003

1. Page ads (dynamic, static pages, video ads, and what you don't know)

2. Push notification (no brain notification, no brain advertising push)

3. Background traffic (system in order to care about you, applications in order to meet your habits, understand your habits to collect data)

4 video applications (do not Xiaobian say it)

5. Online games (previously said, do not say here)

6. Mobile phone hotspot! (Because it was treated as a Wi-Fi hotspot, the background update Shenma started working, this is particularly dangerous)

These six basics are the most important considerations for the consumption of traffic. The first three points are basically accepted passively, unless you manually adjust the permissions/settings to a certain degree of relief, the latter three are basically the use of active consumption of traffic. To be honest, Now that you have less than a gigabyte of traffic, the last three will be farewell. Xiao Bian also has to say here, outside the Wi-Fi can not even connect! Especially those unclear Wi-Fi signals, some customized routing system can collect all kinds of information, including the password you entered, account number, and even spending to Shenma can intercept! Safety first!

How to choose the data plan

004

Now the three major carriers + third-party operators provide traffic packages are mainly divided into several types, conventional packages do not say, the second is the local flow packets, are generally GB start, in some areas of the campus package can reach more than ten GB The price is still relatively cheap, you have to say the shortcomings, that is, local traffic is limited, travel, winter vacation home is a little troublesome; the third is the daily rent card, 1 yuan / day 500MB, traffic is also Local, but this is more flexible, with no money spent on the use of traffic, flow is not accumulated on the same day; the fourth is open-ended, the price is generally around the level of 200 yuan, claiming that there is no limit to the actual flow, For example, China Unicom's ice cream package, the first 40GB traffic is not limited speed, the excess part to be reduced to 7.2Mbps level, to be honest, Xiao Bian think the card is bigger.

As for Xiao Bian, the daily traffic consumption is relatively high. It is better to buy the second type, the price is moderate, and the limit is small. Daily use is sufficient. Users with strong mobility can choose the third daily rental card. For example, if there is a temporary need for a lot of traffic emergency, one yuan 500MB can also be accumulated, and how much is spent. After spending a few days without spending money, billing is more flexible and more cost-effective. The most not recommended is the last so-called unlimited package that Xiaobian said. The absolute price is not cheap, or there is a speed limit. The significance is not significant.

Mechanical Buzzer

The mechanical Buzzer uses a magnet to move a reed up and down quickly to emit a lower-pitch buzz! It's quieter than the piezoelectric buzzer but uses more power, so you the terminals will have to be closer to the battery packs. To use them, you'll need to match the wire colors to the wires from the battery pack.
