Why does the charger get hot??
For the correct answer to this question, you need to rephrase the question: why is wireless charging less efficient than wired charging??
The answer is simple. Suffice it to recall the school physics course.
When transmitting current through a wire, the efficiency is quite high if a high-quality wire is used. With its help, most of the current reaches the smartphone. Heat dissipation to the environment is minimal.
During wireless charging, a significant part of the energy is dissipated and converted into heat, into heating the charging elements and the smartphone itself.
Does this mean that wireless charging cannot be used??
Known Wireless Charging Issues
Since wireless charging generates a strong electromagnetic field, there may be problems with wireless networks and some smartphones may start to malfunction.
For example, a poor-quality cable to the screen can lead to interference on the display, similar damage to the speaker soldering can lead to rustles in the audio path.
Low-quality wireless chargers can “make noise”. emit a high-frequency sound, which is accompanied by induction.
Since charging has to send regulating packets, low-quality models may supply over or under current. In addition, the battery may be overcharged.
Only iPhones with built-in, native wireless charging are insured against this, as iPhone 8 and iPhone X limit the charge level to 80% when the battery heats up.
But not before. A sudden power surge can damage the smartphone if the temperature rises abruptly.
If iPhone is connected with a Lightning cable to a computer USB port or to an AC adapter, it will charge through the cable and will not use wireless charging.
The relationship between heating and battery life
Does this affect the life of the iPhone battery? Certainly. But not so much as to give up a convenient way to keep the gadget always with a full battery.
- likely wastes charge cycles;
- causes the battery to heat up constantly, albeit slightly.
These operating conditions are stressful for any LiPo cell. But what is there. for any batteries, constant heating is harmful.
The flow of current during electromagnetic induction is impeded by metal elements. for example, a plate for a car magnetic holder or a cover covered with silver paint (silver, paint based on aluminum powder).
A smartphone with a battery cover, a thick cover or a metal case can behave in the same way.
All this can lead not only to the complete inoperability of charging, but also to additional heating of the case.
Wireless charging affects the battery in the same way as others. The difference is almost impossible to notice.
Fast charging, wired and wireless, destroys the battery faster than usual.
Constant connection to a charger is harmful as it wastes stock.
Running “heavy” applications while charging can cause severe overheating.
When charging wirelessly, network surges are even more dangerous. It is advisable to connect them to stabilizing devices.
iPhone 8 Wireless Chargers
The main harm comes from poor quality chargers and cables.
Well, and most importantly: buy good, high-quality wireless chargers. And only in proven places. Otherwise it will be like this.
How wireless charging works?
Most smartphones equipped with wireless charging provide it in accordance with the international Qi standard (read “Qi”).
According to it, 2 flat coils of wire are used to transfer energy from the charger to a smartphone, be it a Samsung or an iPhone.
One of them is the base and is connected to an energy source (a power supply connected to a 220V AC outlet), and the second is inside the charged device and is a receiver.
During operation, the initial detection occurs as a result of the deviation of the change in capacitance or resonance of the transmitter coil.
It is enough to touch the smartphone with the corresponding Qi-coil under the lid to the charging base, and the process of energy transfer begins. charging the battery.
To control the charging process, start or stop it on time. To do this, the Qi base and the Qi receiver are able to exchange system information.
Once the object has been detected, the base station checks to see if the Qi-compatible device is located on it and transmits data. If it sends a response signal, charging starts.
During the charging process, the Qi device sends out control data packets to adjust the power level and finally stop charging when the mobile device is fully charged.
How Wireless Charging Affects iPhone Battery
Now is the time to figure it out: is it possible to use wireless charging for the iPhone? Or really because of this, the battery of the smartphone breaks down faster?
Wireless charging rules
How to Extend iPhone Battery Life While Using Wireless Charging?
It is enough to follow a few simple rules. Exactly the same as when using conventional, wired charging. A quality accessory, cable to it and power supply is the main guarantee of safety.
Other rules are not so binding. After all, 20% battery degradation is not really noticeable. And we change smartphones at least once every 2 years.
If these figures are scary, it is enough to remove the smartphone from charging after replenishing the battery to 80% and, in principle, do not store it on the charger.
It is also not worth using power-consuming applications while charging, especially 3D games or navigation programs that force the processor to work at maximum frequencies. This leads to overheating.
Simple adherence to the rules will make using the iPhone much more pleasant and reliable.
How long does it take to charge iPhone 11?
There is no fast charging included with the iPhone 11, unlike the iPhone 11 Pro and Pro Max. IPhone 11 users get an old 5W PSU that charges a smartphone in 3 hours 45 minutes.
Why wireless charging is harmful?
Wireless charging harms the battery
In order to transform energy from one type to another, a considerable part of it must be spent on the transformation itself. For gasoline engines, the efficiency is barely close to 30%, for electric motors it is slightly higher. May 27, 2020.
