I approached Wireless charge Phone to Phone as a practical experiment rather than a promise of replacing a charger. Its purpose is straightforward: it presents wireless reverse charging as a way to move power from one phone to another. That immediately makes it interesting for a very specific situation—one handset has usable battery left, another is close to shutting down, and there is no convenient cable or wall socket nearby.
The app comes from Masivapp and sits in the Libraries & Demo section, which is a useful clue about how to understand it. I would not treat it like a full charging utility with a guaranteed hardware result. It is better viewed as an accessible demonstration and guide around phone-to-phone wireless charging. The store summary is brief, but the practical question is much more important: what happens when I actually try to turn one phone into a temporary power source?
From a low-battery problem to a realistic charging attempt
My starting condition was the familiar travel problem: a phone with enough battery to help, a second phone that needed assistance, and no desire to carry a separate battery pack for a short emergency. In that situation, the app is appealing because it focuses attention on a feature many people have heard about but may never have tested. It gives the idea a clear place on the phone instead of leaving it as an obscure setting or a confusing hardware specification.
The first important distinction is between explaining wireless reverse charging and creating that capability through software. An app cannot add a physical charging coil to a handset that does not have one. The receiving and sending phones still need compatible hardware and the appropriate system support. That limitation is not a flaw unique to this app; it is the central condition of the entire workflow. I found it useful precisely because it encourages a user to think about compatibility before assuming that placing two phones together will work.
That also affects who should install it. If you regularly carry two compatible devices, lend your phone to family members, or want to understand a reverse-charging option already present on your handset, this app has a clear purpose. If your phone has no reverse wireless charging support, a short cable or a compact power bank will be the more dependable answer. The app cannot turn an unsupported model into a wireless power bank.
Checking the starting devices before touching settings
I would begin by identifying which phone is meant to send power and which one is meant to receive it. This sounds obvious, but it prevents a surprisingly common mistake: starting with the lower-battery device as the source. The donor phone needs enough reserve to remain useful after the handoff, while the receiving phone should be positioned as the device that needs a small recovery rather than a complete recharge.
Next, I would check the phone settings and hardware documentation for reverse wireless charging or a similarly named power-sharing option. The exact wording can vary by manufacturer, so I would not expect the app to replace the system controls. Its value is in helping frame the process, while the actual radio, coil, battery protection and charging behavior remain dependent on the devices themselves.
There is a useful trade-off here. A phone can be the stronger device in terms of battery percentage but still be unsuitable as a wireless source. Conversely, a compatible donor with a high charge level may lose power more quickly than expected because wireless transfer is not perfectly efficient. I would therefore treat the operation as an emergency top-up, not as a way to transfer an entire battery from one handset to another.
Moving through the setup without expecting magic
Once the source and receiver are identified, I would open the app and use it as the starting point for the procedure. The important mental step is to separate the app interface from the physical action. The screen may make the workflow feel simple, but the real handoff happens between the backs of the phones, where their charging hardware must align closely enough to communicate.
I would remove thick cases, wallets and magnetic accessories before trying. This is one of the most practical tips for avoiding a false conclusion. A case that is harmless during ordinary wired charging can create too much distance or interfere with alignment during wireless transfer. I would place the phones back-to-back on a stable surface, rather than trying to hold them in midair, because even a small shift can interrupt the connection.
At this point, patience matters more than repeated tapping. If the receiving phone does not show a charging indication, I would move it slowly across the back of the donor phone instead of assuming the app has failed. Wireless coils are not necessarily centered in the same place on every model. The most reliable position is determined by the hardware, not by the visual center of either screen.
The app is most useful when it turns a vague feature into a deliberate test. It cannot remove the need for compatible equipment, careful placement or a stable surface. What it can do is make the user approach those conditions in the right order, which is much better than randomly pressing settings and hoping for a result.
Managing the handoff between two phones
The handoff is where the workflow becomes more demanding than a normal cable connection. With a cable, the plug usually defines the connection point. With reverse wireless charging, the two phones must remain aligned, and either device can move when someone picks it up, receives a notification, or changes the angle of the surface.
I would keep the screens visible during the first attempt so I could confirm that the receiving phone actually recognizes the transfer. A charging icon or battery animation is more meaningful than simply seeing an option enabled in the app. If the indication disappears, I would reposition the phones rather than leaving them together for several minutes without checking.
Another useful habit is to agree on which person owns the donor phone. In a family or travel situation, the source phone may be needed for navigation, calls or authentication. If it is also being used to charge another device, moving it around can break the connection. I would place the donor on a table and let the person with the low battery keep the receiving phone nearby only if the alignment remains secure. Otherwise, a short cable is less elegant but easier to use while walking.
The physical handoff also exposes a limitation that a store summary cannot communicate: wireless charging is sensitive to movement. This makes it suitable for a parked car, a café table, an airport seat or a hotel nightstand, but less suitable while both people are actively using their phones. I would not plan on maintaining a stable transfer during a hike or a busy commute unless the devices can be supported securely.
What the result means in everyday use
For me, the useful outcome is not a fully charged second phone. It is enough extra power to finish a journey, send an important message, display a boarding pass, call a taxi or keep navigation alive until a normal charger becomes available. That narrower expectation makes the feature feel practical instead of disappointing.
Imagine arriving at a station with one phone nearly empty and another still comfortable for the rest of the trip. I would identify the stronger phone as the donor, remove both cases, activate the appropriate system function, and place the devices together while sitting down. I would watch for the receiving phone to acknowledge the transfer, leave them undisturbed for a short period, then check whether the low-battery phone has gained enough reserve for the next part of the trip. If the connection keeps dropping, I would stop wasting time and switch to a cable or power bank.
This is also a useful emergency workflow for parents. A child’s phone may need just enough charge to make a call, while the parent’s device has a larger reserve. The app can help explain the idea and organize the attempt, but the parent should still decide how much battery can safely be shared. The donor phone should not be drained to the point where both devices become liabilities.
In a work setting, the same process can help when two colleagues have compatible phones and only one has access to a wall outlet. The advantage is convenience: no need to find the exact cable type for the receiving device. The disadvantage is that both phones are tied together physically, and the transfer may be slower or less predictable than using a dedicated charger.
That comparison is important. A standard wired charger remains better when speed, stability and continued phone use matter. A power bank is better when the recipient must move around, when the donor phone cannot spare battery, or when the devices are not compatible. A built-in reverse-charging feature used directly through the phone’s system may also be preferable for someone who already understands the procedure and does not need an explanatory layer.
Where the workflow breaks down
The first failure point is hardware compatibility. If the source phone does not support wireless power sharing, no amount of repositioning will solve the problem. The same applies if the receiving phone lacks the necessary wireless charging hardware. I would check this before relying on the app in an emergency, because discovering the limitation at the moment of need is frustrating.
The second failure point is heat. Wireless energy transfer can make both devices warmer, especially when one is also being used heavily. I would avoid placing the phones under clothing, inside a closed bag or in direct sunlight. If either handset becomes uncomfortably hot, I would end the attempt and let it cool. The app should not be treated as permission to ignore the phone’s own temperature warnings.
Battery level is another practical boundary. Sharing power from a nearly empty donor phone defeats the purpose, and a receiver that is already warm or running demanding tasks may gain less useful battery than expected. I would close unnecessary activity on the receiving phone and keep the screen off during the transfer when possible. That is a simple way to ensure that the incoming power is not immediately consumed by the display or background work.
Alignment can fail even when the phones are technically compatible. Camera bumps, textured cases and uneven backs can prevent the coils from sitting close enough. I would not force the devices into an awkward position or use heavy objects to press them together. A stable, flat arrangement is safer than trying to create pressure.
There is also a human friction point: people often assume that a wireless connection should behave like Bluetooth, where the devices can be separated after pairing. That is not how this charging handoff works. The phones need to remain physically close and correctly oriented. If a user expects freedom of movement, the usual alternatives will feel much better.
How I would decide whether to keep using it
Wireless charge Phone to Phone is free and rated for Everyone, which makes it easy to try without turning the experiment into a purchase decision. It was released on December 12, 2023, and the current version is 12.0. It supports Android 7.0 and above, so the operating-system requirement is relatively approachable for many Android users. The app has reached over one hundred thousand installs, with an average rating of 4.1 from around two thousand six hundred ratings; that suggests meaningful interest, while still leaving room for mixed experiences across different hardware.
I would recommend it to someone who wants a simple entry point into phone-to-phone wireless charging and is willing to verify device compatibility. It is especially suitable for learning the correct sequence: identify the donor, enable the phone’s supported function, remove interference, align the backs, confirm the charging indication and monitor the result. Those steps are more valuable than simply knowing that reverse charging exists.
I would skip it if my main goal were fast, guaranteed charging. In that case, a wired adapter or power bank is the sensible choice. I would also skip relying on it for a long trip if I had no backup plan. Wireless sharing is a useful bridge to the next outlet, not a substitute for carrying proper charging equipment when the consequences of failure are serious.
My final view is positive but deliberately limited: this is a practical demonstration-oriented app for a real but conditional phone feature. Masivapp has chosen a useful problem to highlight, and the free access makes experimentation easy. Its strongest contribution is helping users understand the complete workflow from battery shortage to physical alignment and confirmation. The honest result is a small emergency boost when the hardware cooperates—not a universal charging solution. If you approach it with that expectation, keep the phones cool and still carry a cable for important situations, it can earn a place in your travel or family toolkit.
