AdapterandA pair of stands
The picture of the adapter was white on 750mA and black per 1000mA. Tello asked to send black to 1000mA, but sent black .. on 800. Okay.

Rearranged the coil in the stand, taking into account the location of the receiving coil in the body. Along the way, I donated the magnetic screen - fragile they. It is now kosher and caught quickly and accurately. The current jumps from 300 to 600 mA. You can still lift the coil somewhere by 0.5 - 1 mm so that the gap is even less.

It seems that the temperature is removed from the same place as in / sys / devices / platform / battery / power_supply / battery / batt_tem, although the testimony there somehow does not inspire confidence, it seems close to truth.
A more accurate getage to the center of the coil leads to a minimum of losses in the heat and maximum of the charging current.
Judging by the time of charge, the night on the stand is enough to charge the device to be accommodated. The stand is connected to native charging 2a.
I also connected to the port of the company, where at the output of only 500 mA. The charging current was only about 200 ... В± 40 mA, which hints at the effectiveness of energy transmission and loss due to jambs of hitting. Slowly, but charging. At least not discharged. It is bad or good, xs. In any case, the sedentary will not give the phone to die.

I did so,Picture from the header about contacts from the Zamlaned Cossack BV-JEKO- Really bullshit. Next to these contacts are empty platforms on the board, on which there is nothing. They are under the shielding casing and do not fit there even to see. We drove.

The search for the adapter with minimal sizes was carried out in order for NFC to work confidently. It is necessary to understand that the antenna NFC "wound" in 6-7 turns (a strip of about 7 mm) around the perimeter of that black rectangle, which on the pictures I have andbzfox Tied to the contacts to the left of the Six Module. Experiments showed partial overlapconnectedantennasconnectedThe adapter leads ... to the partial performance of NFC. That is, overlapping with the edge of the millimeters antenna by 5-6 and NFC reads only Mifareltralight labels - one-time travel. And the top three, which is already MIFARECLASSIC no longer read or knocks on the middle. I was not suitable for this situation and I had to move until I stop. But with minimal analysis of products. The adapter is a coil covered with a thermally insulating film with a controller-fired controller. At the edges, the film can be beaten (at the dynamics) and bundle to insert the NFC antenna there. As a result, it turns out a single coil module: D, which will need to be fastened with the next time. Operating experience will show where to move where to wind, etc. Of course, the shift of the charging coil is not cool down - it does not kosher on the stand. But the antenna bend and cut did not want.

UPD: Qi technology - inductive gear. Imposes restrictions on the mutual arrangement of coils, their size, the distance between them, the presence of foreign objects, screens, etc. The effectiveness of the already low and up to the heap of so many factors of its downgraders. O.O The coil in my stand is one (there are multi-phase solutions). From here - step left to the right =Escape, shootingDisconnection from the charger.
Opening the stand showed that her small coil was stuck not in the center, to which KagbE is aiming intuitively. It turned out that it plays a significant role. I will make a reservation immediately, the tests conducted 50% when charging.
If you take a connected adapter and put it right onto the coil and move a little, then in the engineering menu you can see 780 mA of charging current (I did not become more). That is, the stated 800 mA seems to be achievable. Then begin the nuances. The offset by 5-10-15 mm to the side leads to a sharp decrease in the charge current up to shutdown. Closed the cover of the stand, placed the adapter into the housing, blocked (fully or partially) its antenna NFC, and the most interesting thing - inserted the phone into the body, everything. You have to catch the point of contact .. Contactless charging. Therefore, the overlap is better to exclude immediately.

Will have to go deep in the topic andView on the effect of the sizes of coils on temperature, efficiency and positioning accuracy. I think thatUPD: N. For nothing, they abandoned the topic.If the controller was embedded on the board next to the contacts, and the coil itself is wound on the lid, then its size could be much larger. May not fit the normal layer of thermal insulation with such a battery or simply did not want a boiler to do.
Given the moving in this area in the last couple of years and the state of uncertaintymarketManufacturers found not the best option to insert a flawed QI to the apparatus, which, in general, only compromises the device, but the actual profit will not add. And promising resonant A4WP (Aka Rezence or who he will still become later .. Airfuel) or not ready or expensive.
And the churches are small chopped cabbage on inductive baubles.

And so .. pampering, in general. I do not know what's worse - a broken port lid or overheated battery. o.o.
