Samsung provides you with a new feature for their Glaxay devices and wearable which is the PowerShare, it allows you to share the battery power with the devices that supports the same feature. To know more about it please read the below.
Phones with the Wireless power sharing feature can charge other Samsung devices that are compatible with the Qi charging standard. However, other Qi devices may not be compatible with Wireless power sharing.
A new patent application by Apple suggests a new charging feature could be coming to future iPhones. Wireless power sharing, or reverse wireless charging as it is commonly known, allows you to use your phone as a wireless charging pad to charge another phone or wireless earphones. It's been available on some Android handsets for a while now but this would be a first for Apple.
So I have a z fold 4 and I have a pair of airpods, and when my airpods are dead because I forget to charge them I use wireless powershare, and recently more specifically today powershare won't work, as I'm typing this my phone is at 84%. So pretty much what happens is that I turn on powershare I put my airpods case on the back in my phone and for a few seconds it starts charging then it just stops and I get the error "wireless powershare has stopped working, try removing anything thats between the 2 devices like a case" and yes I do have a case for my airpods case that I removed before charging and it still doesn't work, and before you ask yes it has worked before but I haven't had to use it in a long time.
Alongside standard wireless charging, many of Samsung's phones also feature reverse wireless charging. It's called Wireless PowerShare, and it allows your Galaxy phone to wirelessly charge Bluetooth accessories and other smartphones that support Qi technology. Below is everything you need to know about Wireless PowerShare, how to use it, and the devices that support the feature.
Many other flagship Android phones feature reverse wireless charging, such as the OnePlus 10 Pro and Google Pixel 6 Pro. The feature isn't called Wireless PowerShare on those devices as that's Samsung's specific brand name for its tech. Not all phones with wireless charging will necessarily support reverse wireless charging. You should check your phone's spec list for more details.
Samsung's reverse wireless charging implementation can output 4.5W of power, though the power supplied to the device being charged will be lower since wireless charging does not have 100% efficiency. The power loss from your phone will not be proportional, either. For example, if your Galaxy phone loses 30% power during reverse wireless charging, the other device won't gain the same amount of battery power.
With phones, though, it is a different story altogether. Despite reverse wireless charging an iPhone with my Galaxy S22 Ultra for nearly 1.5 hours, the former only gained about 38% battery. And this was enough to deplete the Ultra's battery from 92% to 31%.
Yes and no. Using Wireless PowerShare generates a lot of heat, which causes wear to a device's battery. This means if you use it regularly, it could be bad for the lifespan of your phone's battery over a long time. Additionally, the unproportionate battery drain means it is not a practical feature that you can use daily to charge your smartwatch, wireless earbuds, or phone.
Wireless PowerShare is a valuable feature to have as it allows you to top up your Bluetooth accessories using your Galaxy phone easily. This way, you can avoid always carrying their chargers with you. However, the limited power output and the unproportionate battery drain mean the feature is not ideal for charging smartphones or other devices with a big battery.
when my s10 got wet, i wanted to try wireless powershare to chsrge my phone using my old s8. Just for future reference, does anyone know how to enable it.. Aside from using the pull down notification bar option as it doesnt seem to be thsre.
Wireless power transfer (WPT), wireless power transmission, wireless energy transmission (WET), or electromagnetic power transfer is the transmission of electrical energy without wires as a physical link. In a wireless power transmission system, an electrically powered transmitter device generates a time-varying electromagnetic field that transmits power across space to a receiver device; the receiver device extracts power from the field and supplies it to an electrical load. The technology of wireless power transmission can eliminate the use of the wires and batteries, thereby increasing the mobility, convenience, and safety of an electronic device for all users.[2] Wireless power transfer is useful to power electrical devices where interconnecting wires are inconvenient, hazardous, or are not possible.
Wireless power techniques mainly fall into two categories: near field and far-field.[3] In near field or non-radiative techniques, power is transferred over short distances by magnetic fields using inductive coupling between coils of wire, or by electric fields using capacitive coupling between metal electrodes.[4][5][6][7] Inductive coupling is the most widely used wireless technology; its applications include charging handheld devices like phones and electric toothbrushes, RFID tags, induction cooking, and wirelessly charging or continuous wireless power transfer in implantable medical devices like artificial cardiac pacemakers, or electric vehicles.
In far-field or radiative techniques, also called power beaming, power is transferred by beams of electromagnetic radiation, like microwaves[8] or laser beams. These techniques can transport energy longer distances but must be aimed at the receiver. Proposed applications for this type include solar power satellites and wireless powered drone aircraft.[9][10][11]
Wireless power transfer is a generic term for a number of different technologies for transmitting energy by means of electromagnetic fields.[14][15][16] The technologies, listed in the table below, differ in the distance over which they can transfer power efficiently, whether the transmitter must be aimed (directed) at the receiver, and in the type of electromagnetic energy they use: time varying electric fields, magnetic fields, radio waves, microwaves, infrared or visible light waves.[17]
In general a wireless power system consists of a "transmitter" device connected to a source of power such as a mains power line, which converts the power to a time-varying electromagnetic field, and one or more "receiver" devices which receive the power and convert it back to DC or AC electric current which is used by an electrical load.[14][17] At the transmitter the input power is converted to an oscillating electromagnetic field by some type of "antenna" device. The word "antenna" is used loosely here; it may be a coil of wire which generates a magnetic field, a metal plate which generates an electric field, an antenna which radiates radio waves, or a laser which generates light. A similar antenna or coupling device at the receiver converts the oscillating fields to an electric current. An important parameter that determines the type of waves is the frequency, which determines the wavelength.
Wireless power uses the same fields and waves as wireless communication devices like radio,[18][19] another familiar technology that involves electrical energy transmitted without wires by electromagnetic fields, used in cellphones, radio and television broadcasting, and WiFi. In radio communication the goal is the transmission of information, so the amount of power reaching the receiver is not so important, as long as it is sufficient that the information can be received intelligibly.[15][18][19] In wireless communication technologies only tiny amounts of power reach the receiver. In contrast, with wireless power transfer the amount of energy received is the important thing, so the efficiency (fraction of transmitted energy that is received) is the more significant parameter.[15] For this reason, wireless power technologies are likely to be more limited by distance than wireless communication technologies.
Wireless power transfer may be used to power up wireless information transmitters or receivers. This type of communication is known as wireless powered communication (WPC). When the harvested power is used to supply the power of wireless information transmitters, the network is known as Simultaneous Wireless Information and Power Transfer (SWIPT);[20] whereas when it is used to supply the power of wireless information receivers, it is known as a Wireless Powered Communication Network (WPCN).[21][22][23]
Electric and magnetic fields are created by charged particles in matter such as electrons. A stationary charge creates an electrostatic field in the space around it. A steady current of charges (direct current, DC) creates a static magnetic field around it. The above fields contain energy, but cannot carry power because they are static. However time-varying fields can carry power.[29] Accelerating electric charges, such as are found in an alternating current (AC) of electrons in a wire, create time-varying electric and magnetic fields in the space around them. These fields can exert oscillating forces on the electrons in a receiving "antenna", causing them to move back and forth. These represent alternating current which can be used to power a load.
The oscillating electric and magnetic fields surrounding moving electric charges in an antenna device can be divided into two regions, depending on distance Drange from the antenna.[14][17][18][24][30][31][32] The boundary between the regions is somewhat vaguely defined.[17] The fields have different characteristics in these regions, and different technologies are used for transferring power:
In inductive coupling (electromagnetic induction[24][45] or inductive power transfer, IPT), power is transferred between coils of wire by a magnetic field.[18] The transmitter and receiver coils together form a transformer[18][24] (see diagram). An alternating current (AC) through the transmitter coil (L1) creates an oscillating magnetic field (B) by Ampere's law. The magnetic field passes through the receiving coil (L2), where it induces an alternating EMF (voltage) by Faraday's law of induction, which creates an alternating current in the receiver.[15][45] The induced alternating current may either drive the load directly, or be rectified to direct current (DC) by a rectifier in the receiver, which drives the load. A few systems, such as electric toothbrush charging stands, work at 50/60 Hz so AC mains current is applied directly to the transmitter coil, but in most systems an electronic oscillator generates a higher frequency AC current which drives the coil, because transmission efficiency improves with frequency.[45]
