Daily Maintenance Required:
1, cell phone battery do not wait until no electricity before charging.
In general, we all have an idea that the cell phone battery power should be fully released and then charge more good basically is correct, since most of the rechargeable batteries we used to use were nickel-hydrogen (NiH) batteries, the so-called memory effects of Ni-MH batteries can lead to a sharp reduction in battery life if they are not recharged. That's why we use the last drop of electricity to start charging. But the current mobile phone and general IA products are mostly lithium (LI) batteries, and lithium battery words have no memory effect problem. If we wait until the full use of electricity after the charge, but will make lithium batteries inside the chemical material can not respond and life expectancy. The best way to do this is to recharge your batteries and keep them at the top of the grid anytime, so that your battery will be available for a long time. This is the message from the manufacturer and is tested by itself.
2, when the phone is charging, do not answer the phone!!
The reason is that when the phone is charging, there is a potential danger of calls to answer. India has a 31-year-old business manager in the insurance company, a young man, more than 10 days ago when the phone was also the charger to answer the phone, after a few seconds of a large number of electricity through the phone, the young man was dropped to the ground, the family found when the finger burns, weak heartbeat, and has lost consciousness After the emergency delivery to the hospital, the doctor announced the death of the hospital. Mobile phone is the most commonly used modern invention. However, we must also be alert to the danger of lethal instrumentation.
3. Do not use the cell phone when one is left
The reception Mange and only one cell, compared to the intensity of the launch is 1000 times times the difference. So ... The person who often speaks mobile phone ... Be careful ... ^0^ and yesterday got a very important message from a mobile phone provider, that is, when you find that the phone's message strength is only one grid, it is better to hang up or switch to a public telephone. Do not gush, the mouth foam horizontal fly, thick affection honey meaning, can't stop, endless ... Why is that? We all know that the electromagnetic wave of mobile phones has always been a worrying problem. And the phone is designed to in poor reception areas can still maintain a considerable quality of the call, will strengthen the mobile phone's electromagnetic emission intensity. When the reception Mange and only one cell, compared to the intensity of the launch is 1000 times times more than the difference. Electromagnetic wave intensity up to 0.6W (W) 0.6W How strong is it? I can't specifically describe what it does to your head, but it can be compared with two examples:
1 The trumpet diameter of about 4 centimeters of small radio volume open to the largest and then affixed to the ear, such noise energy generally 0.25W, less than 0.5W.
2 Put the finger in front of the laser beam of 0.1W output strength (equivalent to the optical fiber network?) D Trunk Energy) you will have a burning sensation in a few seconds, can you endure these two situations for a long time?
So how do you make sure that the 0.6W electromagnetic wave clings to your ear?
