The smartphone “charging wars” are predominantly fought on the wired entrance the place some firms already handed the 100W thresh maintain supplying you with a full 0-100% cost in round and even underneath 20 minutes. However once in a while the battle is carried over on the wi-fi entrance the place makers are additionally reaching speeds that had been unthinkable a few years in the past.
One such system is the vivo X80 Professional which we reviewed not too way back and which helps 50W wi-fi charging. The one catch is that you simply want a specialised wi-fi charging stand. We just lately acquired one such charger at our workplace – vivo’s 50W Wi-fi Flash Charger and at the moment are able to report on what it permits.
As a way to obtain blazing quick charging occasions, vivo X80 Professional has a dual-cell battery with two cost pumps – an industry-standard method used on most new flagship telephones these days. With its mixed battery cell capability of 4,700mAh, X80 Professional managed an unimpressive 79 hours in our proprietary battery endurance check. X80 Professional ships with a bundled 80W FlashCharge adapter (20V / 4A) and corresponding USB-C cable. In our wired charging check, we reached peak charging energy of 65-66W at 17V and 4A leading to a full cost of 39 minutes.
vivo claims the 50W Wi-fi Flash Charger can cost up the X80 Professional to 50% in 23 minutes whereas a full cost ought to take 50 minutes or simply 11 extra minutes than the 80W wired FlashCharge answer. The corporate clearly confirms the precise charging energy is “dynamically adjusted” and is “topic to precise use” – that means you shouldn’t anticipate 50W energy blasting the telephone always.
The vast majority of gadgets that assist Qi-wireless charging can cost at as much as 15W speeds. You’ll want to make use of a vivo or iOOO charger that helps 66W (or greater) FlashCharge and a appropriate USB cable to achieve the 50W wi-fi charging speeds.
Some fast phrases on the 50W Wi-fi FlashCharge charger. It includes a dual-coil design that permits you to place your telephone in both portrait or panorama orientations – the latter being helpful if you wish to watch a video whereas your telephone is charging. The cradle includes a 60-degree tilt and a built-in cooling fan on the underside, reaching as much as 3,600 RPM.

The charging pad brings a white and silver look with a shiny floor on the charging cradle space and a frosted end on the again all made out of plastic. There’s additionally a frosted clear bit upfront that holds the system you’re charging. Vivo is bringing a particular nighttime charging mode on its supported telephones the place the fan will restrict itself to 27Db in order that your sleep is just not disturbed. It will not be almost as quick, however that does not actually matter in case you are overnighting your telephone anyway.
The again of the charger includes a USB-C port so you possibly can safely swap out cables if wanted. Talking of cables it’s a bit disappointing to see no cable or energy adapter within the charger’s retail packaging given its $70 retail worth (at present right down to $40).
The wi-fi charger weighs in at 196 grams whereas the X80 Professional’s 80W bundled charger and cable are available at a further 150 grams so in the event you’re touring someplace and wish to carry your 50W FlashCharge charger and use its most energy word that you simply’ll be carrying almost 350 grams value of apparatus, not counting the telephone itself.
In our testing, we measured 58 minutes for a full cost on the vivo X80 Professional. That’s 8 minutes greater than the vivo claimed 50-minute full cost time. We must always issue within the room temperature as a variable which will have altered the outcomes. From our knowledge, we will see the telephone reached a 11% cost in simply 5 minutes and obtained to 50% in 27 minutes. The X80 Professional sat at 89% after 50 minutes and reached 100% after 58 minutes.

The charger’s fan was barely audible all through the cost cycle and didn’t trigger any disturbance. We didn’t discover extreme warmth coming from the telephone in the course of the charging process. We additionally took the system off of the charger as quickly because it reached 100% and it was barely heat to the contact than in its idle state however not unbearably scorching like after a difficult benchmarking session.
For the sake of comparability, we additionally tried out an iQOO 9 Professional – one other telephone that formally helps the 50W Wi-fi Flash Charger. The system shares the identical 4,700 mAh dual-cell battery because the vivo X80 Professional. The iQOO 9 Professional managed a full 0-100% cost in 47 minutes – 13 minutes faster than its vivo X80 Professional cousin. The telephone was already at 18% 10 minutes into the check and reached the 50% mark in 24 minutes. From there it was clean crusing with 62% after half-hour, 84% in 40 minutes and the complete 100% in 47 minutes.

Final however not least we additionally examined final yr’s vivo X70 Professional+ which was the primary telephone to assist 50W wi-fi FlashCharge charging. It accomplished the complete cost in 70 minutes – 7 slower than the newer vivo X80 Professional and 23 minutes slower than the iQOO 9 Professional. All of this whereas carrying a smaller 4,500 mAh battery reveals us the developments made by vivo in a single era of flagships.

So what are the takeaways from this little experiment? Wi-fi charging is getting significantly quick and is slowly creeping up on wired options. Sadly, there are just a few obstacles to entry with all of the totally different proprietary chargers and energy cables that solely work with a choose few handsets from a single maker. Here is a recap of our findings within the type of chart and we have added MagSafe and charging occasions on an iPhone 12 Professional as a comparability for good measure.
So even when your model new flagship helps 50W wi-fi charging you’ll nonetheless must shell out a further sum for a selected wi-fi charger to benefit from that characteristic and it should be paired with the appropriate cable and plug to work.
On the finish of the day having a telephone that may totally cost its battery in underneath 50 minutes and not using a plug is a reasonably cool feat and we will solely hope extra manufacturers carry this tech to their gadgets heading ahead. We additionally hope that makers will work to unify their wi-fi quick charging options so we do not find yourself in a state of affairs much like the wired charging the place you need to decide between velocity and compatibility, when buying your chargers.
