The Palm Pre was ahead of its time – it introduced the world of wireless charging into the mobile world. Unfortunately, despite all its innovations, the phone has not caught up. In fact, manufacturers were unaware of the wireless charge until 2013, when they started pushing it more actively.
The "fast" wired load was born quite late in the game – 2014. The term is not defined precisely; we count the phones that can exceed 10W provided by the simple USB key.
We have already talked about the struggle between wireless charging standards. Spoiler: finally, the Qi of the Wireless Power Consortium is imposed as the winner. On the front line, there were two first players.
Sony Xperia Z2 HTC One (M8) • Xiaomi Mi 4 • Oppo Find 7
Qualcomm introduced Quick Charge 2.0 with its Snapdragon 800 chipset (and other family chips). It stood up to 18W, although 15W is by far the most popular option (it is still today). Phones such as the Sony Xperia Z2, HTC One (M8), LG G4 and Xiaomi Mi 4 were among the first to offer QC2.0.
In the other corner was Oppo Find 7, the first VOOC payphone, which operated at 20W. Pretty impressive for the beginning of 2014, when we consider that some of the most expensive jewels today do not exceed 15W (we look at you, Apple and Samsung).
Despite a quick start, wireless charging has been slow to gain popularity. As you can see from the table below, the fast wire feed has quickly passed and is currently on the most popular phones.
Of course, today's flagship products often offer both wireless and fast charging, but it's a relatively new development that began last year. Wireless fast charging has also begun to gain ground. We have not put it on the map because there is actually only one relevant data point, but starting this year, the most popular phones with wireless charging can exceed 10W.
Huawei and Samsung lead the charge to a 15W fast wireless charge, although the Galaxy maker is lagging behind in terms of wired charging speeds (25W vs. 40W). These two machines are among the first to implement a reverse wireless charging (Huawei with the Mate 20 Pro last year, Samsung with the Galaxy S10 this year).
In fact, while some brands share technologies (eg, Oppo, vivo and OnePlus, as well as Huawei and Honor), fast-cabling load standards are quite fractured. The USB-IF is trying to put everyone under the USB Power Delivery banner, but its only notable success so far is the Quick Charge 4.0+ compatible support.
In the end, this competition seems to have been a good thing – the loading of Qi by WPC was virtually unchallenged (as competition between PMA quickly failed), wireless charging took time to gain ground .
