Today, a cellphone is popular, so everybody uses a cellphone everywhere. However, many people complain that hours of battery use is not enough. When consumers try to buy a cellphone, they significantly consider hours of battery use, so cellphone companies develop a better battery.
In this case, we can save more battery running time with three things – adjusting screen brightness, turning off unnecessary applications and functions, and I can assume that these tips will help save your battery much more.

            First, adjusting screen brightness is an easy way to save the battery efficiently. In Android cellphones, for example, screen brightness takes over 45% in the usage of the battery. This percentage means that screen brightness takes the most part of the battery usage. If a user sets
a cellphone as auto adjusting screen brightness, in most cases, a cellphone will be set to the highest brightness. However, it is unnecessary. 50~80% of a maximum brightness is enough to use. For sure, it really helps to save the battery and this is why a cellphone is automatically set a lowest brightness when it has less than 5% of the battery.

            Second, turning off unnecessary applications is also helpful to save the battery. In Android cellphones, for example, most applications are not turned off when a user clicks the home button. These applications need to turn off manually.
If a user lets applications run in the background, it keeps running and using more batteries.
The battery is wasted for nothing. Therefore, we need to turn off unnecessary applications.

            Third, turning off unnecessary functions is a good way to save the battery. All functions in a cellphone require more battery usage. For example, vibration, screen rotation, Bluetooth, etc. These functions are useful and sometimes we need these functions. However, we really don’t need to turn these on every time. It is similar as turning off unnecessary applications. Therefore, we need to turn off unnecessary functions to save more battery.

            

     A cellphone is upgraded with technology and it takes an important part of our lifestyle. Even though a cellphone is getting better, the battery problem is always limited our cellphone usage. However, if cellphone users remain these useful tips in their mind, they can use their cellphones longer. Reminding a small guideline can makes a big difference.

My cellphone helps to guide my way

Have you ever lived without using  your cellphone? You might feel uncomfortable. Not only a cellphone is used for phone call, but also a cellphone is used for a multiple way. By passing the time, cellphone is placed as a very important part in our life. Cellphone changed our life rapidly. High technology gives better life and I would like to describe a paradigm of telephone, a usage of a cellphone as an multimedia, a usage of a cellphone. 

First, invention of cellphone changed a paradigm of telephone. In the past, people couldn’t leave telephone during they are on a talk. If people need to do other stuff or go outside, they need to quit their calling first. However, after the invention of cellphone, people don’t need to stay at specific area anymore. They can call to other people whenever they want. A mobility on the cellphone is a very innovative idea because it is a new technology and this is the thing that people alwasy desire it.

Second, a cellphone can be used as a multiple electronic devices. In the past, a cellphone was developed for calling only. Today, people assemble various functions in cellphone. For example, the size of digital camera market is decreased because cellphone already included camera function. The video game market is same, too. When people wanted to play some video games, they need to buy specific game consoles first. Pong and Super Mario are a great example of this problem. Today, however, people can play video game in a cellphone. For sure, some exclusive games like Pokémon and Mario are still released for specific game consoles, but a cellphone affects a huge change in the video game market.  

Third, a cellphone is a very useful machine to get information easily and quickly. Before the invention of cellphones, it was very difficult to get new information. People needed to go library and find information in books or computer. After the invention of cellphone, people don’t need to go to the library anymore. They can use cellphone and find any information whenever they need. A mobility of cellphone boosts to spread these information for all. Knowing how to search information became more important part. 

Cellphones are a revolutionary change. The usability, integrity, and convenience of cellphones make an affluent society and help us to live a better life. Cellphones are a useful tool. However, some people still couldn't get any authority to use cellphone cause of their difficult life phase. Therefore, we need to keep upgrading cellphone technologies and disseminate these for everyone.
