Batteries can almost certainly be the technological components that have evolved the least in recent years. But although the battery itself does not evolve and they continue to be manufactured in the same way, with nuances, yes, the charging systems advance and thanks to that today we enjoy not only fast charges of different speeds, but also of wireless charges.
They may not be the most widespread today, but wireless charging is also at a point of maturity where manufacturers are experimenting with and customizing them. Hence the latest release of the Mi 10 Ultra with its 50W, one more to add to the list and one of the excuses for us to come here today to check How well do the wireless charges that we find in the mobile market perform?.
Xiaomi and Huawei mark the speed limit right now
The only difference, although substantial, between wireless charging and normal charging is precisely the cable, so its principles are the same. We have a highway with lanes of a certain width and, depending on the load model, we will have more or fewer lanes at our disposal. Volts and amps, the combination that gives rise to the number that manufacturers often talk about: the maximum load watts. That is, the maximum amount of electricity that the mobile can supply to the battery.
So once wireless charging has matured, manufacturers start to play with these voltages and amperages to reduce charging times trying not to print too much heat and therefore damage the battery itself. Xiaomi has been the last to put a proprietary wireless charging on the market and it also does so with the fastest that we enjoy right now. My Wireless already reaches 50W at Xiaomi Mi 10 Ultra, which translates into 10V and 5A.
With 50W, Xiaomi is currently in the lead in terms of maximum wireless charging speeds
But the manufacturer already shows signs of wanting to go further and seems to have in preparation a 200W fast charge for the not too distant future. Meanwhile, we can face these Xiaomi 5Ws with their competition in the market. And to do this, we can start with Samsung, one of the manufacturers that has opted the most for this type of charge since its inception. The Samsung Galaxy Note 20+, for example, allows a wireless charge of up to 15W and, this is interesting, a 9W wireless reverse charge. That is, it can charge other devices wirelessly with the same system that it charges itself.
But Huawei knows well what this reverse charge is, as the Chinese manufacturer was the first to put it on the mobile phone market. The Huawei Mate 40 is one of its last terminals and also arrives with 50W wireless charging matching Xiaomi. So for now, Xiaomi continues to lead with its 50W of wireless charging and a technical tie with Huawei.
Apple is another of the manufacturers that has offered wireless charging for relatively recently. However, the Americans seem far from competing against the speed of their rivals since at present, wireless chargers designed for the iPhone stand at 15W, the maximum that for now the Cupertino allow. With the incentive that they also have the MagSafe system ported directly from their Macs.
Sony offered Qi charging on some models, but dropped the option in later generations
Another competitor in the mobile phone market is OPPO. The Chinese manufacturer has also implemented wireless charging in some of its models for a couple of generations, and is currently at the point before the last Xiaomi presentation. OPPO also offers wireless charging of up to 40W. Motorola also targets this market with a Qi wireless charging (the same as in all) of up to 15W, the same that LG uses.
We don’t want to leave out Google, which goes up to 12W wireless charging though with its official wireless charger. We would have included Sony in this list but the Japanese manufacturer stopped implementing wireless charging a few models ago. Those of the new nomenclature, Xperia 1 Y Xperia 5, they no longer carry it and we do not know if at some point he will decide to take a step back to return to the contactless charging market. We leave you a table so that you can check the maximum speeds of each manufacturer.
