Smartphones offer more and more solutions focused on the battery so that we can take advantage of the mobile, as well as the rest of the devices in any place, time and situation. These measures to try to alleviate the problems with autonomy lead us to run into others, which in this case have to do with reverse wireless charging.
This technology that may seem futuristic to many, has been present in high-end mobiles for several generations and will surely continue to gain followers. However, ignorance or failures of wireless charging between devices can lead us to forget this technology or give up. So that it does not happen to you, we are going to help you with each of the possible situations.
What does it consist of?
Before proceeding to find solutions to the problems that we may face, it is necessary to know what this advantage is about, which for many may be something totally new. Reverse wireless charging , as its name suggests, is an option integrated into some mobiles to emit its energy to others. Whether they are headphones or mobile phones, we will be able to give up the battery of our smartphone for the benefit of others.
A mechanism that requires its own technology, since it is through some coils included in the internal wall of the telephone that we are going to proceed to send the energy. A posteriori, you only have to put the sending mobile and the receiving device back to back to see how the energy is exchanged between them.
Problems of this technology
As with any other system that helps us recharge the energy of our devices, there are several failures or errors that we can find when trying to charge other equipment with our smartphone.
The mobile does not emit the charge
The first place where we put our sights is on the mobile in charge of transmitting energy, which may be behind many of the failures before which we run into. For those cases where no matter how hard we try to test mobile phones with wireless charging or devices and we find that nothing happens, the problem seems easy to locate.
It will be necessary to start it up. Unlike the basic wireless charging, in this case we have our own option on all mobiles for not always carrying it on. Therefore, before giving power to a friend or family member, we have to follow a simple process on the smartphone that consists of turning on the reverse charge .
In each mobile the menu may be in a different area, but it is mostly hidden within Settings> Battery. Just by activating the wireless charge sharing option, the smartphone will be ready and ready to charge mobile phones, smart watches or headphones.
I can’t load anything
In case we have launched the reverse wireless charging function and it still does not work, we have to consider other options. Before thinking that the terminal or this charging system is damaged, we must check that the device we are trying to power without cables supports it, as it does not happen with all.
Whether it is a smartphone or a device, it must support wireless charging while ensuring that you do not have an option explicitly intended for anti-rabies charging. If so, we will have to activate it or it will be impossible for it to work at some point. Important, it does not have to have reverse charging, only wireless.
It stops
For all those who have encountered that reverse wireless charging stops working at a certain point, they should know that it has a limit. The main intention of this technology is based on ensuring that the battery of the mobile that emits its energy does not reach the minimum and we run out of battery in it.
We can decide at any time when we want the reverse charge to stop, choosing a percentage within Settings> battery and reverse wireless or wireless charging. The recommended is at least 30% which will be enough to endure with several hours of autonomy. But another reason for it to stop will be that the device we are trying to charge has reached 100% or 80% in some cases, which would be to have successfully completed the purpose.
Faults and disconnections
Another problem that users usually face when using reverse wireless charging is in the failures that occur at the time when the power is being transferred from the mobile . Some errors that prevent the process from being carried out correctly and the reason can be as simple as that the case of the smartphone or one of them is very thick and prevents its correct operation.
But it can also happen because we move the terminals and even because there are metal objects nearby that will cause errors in the process in an unexpected way. It will be impossible in those situations to get the process to complete. To solve it we would only have to remove the protection covers, avoid movements and leave it on surfaces and / or areas that do not affect by magnetism.
It takes a long time to charge
In social networks and in photos, what is repeated the most and for which reverse charging is criticized is because it requires more time than desired to complete the battery transfer . This is so because the mobile does not have the same capacity to withstand high power as a home shrink with its corresponding transformer. As much as we try to solve it, there is currently nothing we can do to improve it.
Other derived problems
Although it is not a failure that affects the progress of the reverse charge, we must remember other problems that users may experience while it is being carried out. The main one is that the smartphone is going to lose coverage by having another one that also needs it so closely and also makes use of magnetism. But also, we can find that the mobile heats up.
And by cable?
Although we have talked at length about reverse wireless charging, you also have to count that some smartphones offer this same cable-based charging and not through contact. In these cases things do not change too much, because there are also load limits so as not to leave the main battery without battery, but at least there will not be those limitations to have to place one mobile on the other and we will only be linked by the cable. In fast charging hot springs there are no differences either, as there is also a limit that cannot be compared to the traditional charger.
