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.
