Hot when used Apple phone users have had the experience of mobile phone charger, hot almost no way took for this situation, how to deal with mobile phone charging case hot it? Really it is charged to blame it? This R sister to recommend some experience.
With the deepening mobile entertainment needs of people for the lack of exposure to cell phone battery life is becoming increasingly apparent, so the battery technology bottleneck faced barriers, many manufacturers came up with a compromise, and that is fast filling. In fact, for many people, fast charge is a very good technology, after all, be able to use another form of greatly enhance the phone's battery life.
If I tell you the following can not solve a good place Tianhe District, Guangzhou Tianhe North Road, Metro Plaza, Room 183 (next to the China Mayors Plaza) 4407-4408
But with the popularity of fast charge, another troubled people of the situation there, and that is the problem charger fever, when the peak capacity of entertainment, people will slowly focus attention to the safety level, which is understandable, so charger fever in the end is not a problem? Can what way its cool it? We will focus on this issue to talk about those things charger.
Apple phones are now equipped with high-top, bringing high performance while fever, running large programs or playing games, battery and CPU status fever appears.
While charging the phone, watching videos, or playing micro letter, answer the phone, so mobile phone charger itself is hot, while also consume a lot of power, easily sustained hot. And it recommended charging time, open flight mode play (single) game.
Especially prolonged use of mobile phones, the heat is being trapped piled on the phone, some mobile phone protective shell can not dissipate the heat, it will be getting hot, oh. We do not recommend the phone shell, or use for better heat dissipation rave soft sets of mobile phone shell.
Close GPS navigation, Bluetooth, open in time of need. In the absence of Wifi environment, remember to turn off Wifi, Wifi avoid bad connections, resulting in the loss of power led to the phone warms.
Correct and stable charging cable, rave Apple MFi data line, is certified through Apple (which has a very strict certification requirements, extremely demanding, certified through rate is only 2%), in addition to charging speed PiaPia of use not to hot up the phone, really care for your little apple.
Why charger may have a fever?
Before talk about this matter, we first look at the principle of charger fever, in fact, a great charger heating elements: high-voltage capacitors, switch, high-frequency transformers, these three elements temperature is quite high. To reduce the temperature of these three elements is also not difficult, in general, in the case where the output current constant, high-frequency power transformer is relatively large, high-power high-frequency transformer temperature is much smaller. Simply put, it is to give it extra power, just like small things, like pull carts effortless. Of course, the more easily heat switch, as long as it is sufficient to install a heat sink on the line. However, due to the volume limitations, to reduce the amount of heat is not possible. So, charger fever is inevitable thing.
Understand the principles, we can easily understand why the current charger will heat up:
1, and which first current intensity and ambient temperature about the charger output. With the popularity of smart phones, chargers now increasingly demanding, function machine age 500ma charger has been unable to meet user demand for a charging rate, in front of what we call fast charge appears, in fact, it is a historical necessity, so we see that the current common charger current in 2A above.
2, another addition to the current boost, volume charger is also a key factor for portability, we often prefer the smaller volume charger, manufacturers R & D direction toward the small but also to develop. However, the smaller the volume, the heat dissipation performance is deteriorated, required electronic components are also higher. Take the capacitance, the high voltage capacitors while maintaining the same capacity, the volume is getting smaller and smaller, and even better in terms of temperature and pressure, but the pressure will be enough to breakdown capacitance, temperature enough will burst open capacitor.
3. In addition, the high temperature of the charger with the charger switch also has a great relationship, if the switch specification is not high, the current through, there will be more heat.
[IPhone6 charging fever how to do]
1, the first punch do not have to charge 12 hours, full on the line.
2. Any amount can be charged.
3, a week at best be a complete discharge point and the charging process, that is, from red to full electrical power.
4, iphone mobile phone overshoot protection function! It is recommended that after the phone is fully pulled out! Does not recommend charging for a long time, such as overnight charge.
5, iphone charging to 100% of the time you charge an hour, with a fully charged battery you just nowhere! 100% with the former to be very anti-power half points than the display, the latter not resistant to use.
6, when the battery is too low prompt appears, you should try to start charging.
In fact, in theory, even if the charger fever, cases of spontaneous combustion explosion is also difficult to occur, the official charger are to go through safety tests, to be able to meet the standards put into production, of course, this is only the correct version of the charger, if the cottage charger, is another matter. The stability of the output voltage of the charger itself cottage not as good as the original charger, which can cause slow charging, the charger fever and other serious problems. Spontaneous combustion explosion is what is likely to happen, so we should try to avoid using unofficial channels to buy the charger.
How to avoid heat Charger
Charger eliminates the problem of the cottage, the remaining things relatively simple, we know that, even using the original charger, fever or serious would happen, how to avoid this from happening as much as possible of it? In fact, very simple, in fact, fever and amperage charger and ambient temperature output of a relationship, then we can start thinking of ways to solve this two problems.
1, first of all we can in a cool environment charge. For example, air-conditioned room.
2, try to avoid playing phone while charging, charging will lead to play phone charger than under normal circumstances Working a long period of time will reduce the life of the charger, while the phone itself can also cause fever cases.
3, to avoid over-charging, the phone is full, even trickle charging, the charger can lead to overload, overheat, so when the phone is fully and timely to develop the habit of unplugging the charger, especially not sleep health before charging, unplug the next morning habits.
4, the charger must be placed away from heat sources, in particular, to avoid heating side, so as not to cause excessive environmental charger overheating.
Memorize these four points, charging develop good habits, dangerous naturally, away from everyone.
