Cellphone is very important in daily life, but how to use it in right way and how to protect it? Let me share some tips:
Watered cellphone
If your cellphone has watered, do not press any key, for the water will flow around the circuit board. What you should do is open the cover, get out the battery directly, which prevents the circuit board from damage.
Weak signal
Do not use your cellphone when the cellphone signal is weak. Electromagnetic wave is something that many people pay much attention. When the cellphone signal is weak, it has to work harder than usual, and it will react more radiations. As reported, when there is only one grid of signal, it will react radiations 1000 times more than those when the signal is full, and reach 0.6W. I can not describe clearly how harmful that is, but I can find some examples for you to compare:
Turn up the radio with the 4 centimeter- horn diameter, attach it to your ear, and the noise is about 0.25W, less than 0.5W.
Hand out and put it to the laser with 0.1W, you will feel painful in seconds.
So, what about 0.6W? In order to keep healthy, check the signal before using your cellphone.
Save your battery
If your cellphone battery life becomes shorter and shorter, I’d like to share a tip:
a. Pack the battery with newspaper and put it into the plastic bag. Well wrap the bag, and put it in the fridge for 3 days.
b. Get it out and keep it in normal temperature for two days.
c. Charge the cellphone after 2 days. You will find miracle.

Squeeze the toothpaste in the wet rag, and wipe the phone screen. Believe it or not, it will glitter again.
