Wired is more efficient, you can pick it up and use it while charging, and the cable usually comes free with the phone. What is the point of wireless charging pads?

First, you’re just wrong. You know there are 2 amp wireless chargers, right?
And you’re missing a group that gains MASSIVE benefits from wireless charging, which is the disabled. Imagine your hands never stop shaking and you either have to try to fiddle a USB C into an Itty bitty slot, or just plonk the phone down on a puck. Which one would appeal to you?

No, it’s the ports on phones that are proof of concept, constantly getting full of dust or just stop working correctly. I’ll take a wireless charger, thanks.
I have one scenario where it’s useful. When in the car and entering a parking lot and you have to scan a qr/bar code on your phone, you can easily pick it up and get it out the window. That said, wireless chargers on cars are terrible.

How so? I wired one into my center console and it works like a charm.
I’ve heard lots of complaints from people owning various brands that the built-in wireless charging pads are useless. Regularly cut off, phones don’t stay in place, etc. These are for the regular Toyotas, Hondas, etc., not the high end models.
I have a 6.5 foot cable for the car so I can yoyo that bitch out the window if I wanted to and have it still charging at high rate at all times
I use one in my car - it’s more convienet for short trips or trips with multiple stops. I do keep a cable for longer trips though, especially if I need to keep the screen on for GPS - the wireless charger makes the phone warm enough to stop charging over the course of an hour or so.
Probably if you’re too lazy to grab a cord, line it up with the plug, and press gently but firmly. With wireless, you can just lob it vaguely in the right vicinity and not overstrain your fine motor skills.
I thought it you don’t line it up exactly right it charges slowly and heats up a lot, ruining the battery
if it’s not aligned properly, it should shut off to prevent that from happening. (or, for example, if you place something else that’s metal over it.)
If it’s completely misaligned yes. But there’s a wide spectrum between too far off to even turn on, and perfectly aligned.
This is what magsafe/qi 2 fixes by including magnets which should have been there from the start.
Mine didn’t, unfortunately. It just charged very slow and got hot. Hopefully newer ones are like you say.

Thank you I didn’t realize the wireless chargers used magsafe.
Is magsafe built into the phone, or just in cases?
If you’re using an iPhone(12 or newer, Although not the 16e), then it’s in the phone. The bit in some cases is to add strength for accessories to snap to where it would be on the phone.
You can get MagSafe cases for some Android devices if you want to use MagSafe accessories with them.
My phone case is designed to attach a camera lens, and actually came with magsafe, but I didn’t have any magsafe attachments and ended up removing the magnets from the case because they interfered with the compass, despite promising not to.
The amount of times I have tripped on a charging cord and sent my phone flying…
… but it’s weird that it happened twice, right?
Some charging pads also prop up the phone at an angle, making it easy to read the screen while also not having to hold the phone up. Most phones have their charging port on the bottom, so a phone stand couldn’t be used while charging with a cord.
Maybe I’m old and prefer having the phone in my hand rather than propped at an angle unless I’m watching some videos, in which case my phone would be landscape mode anyways so the port is easily accessible
Apple’s mag safe charger is pretty popular and you can easily hold the phone in portrait mode while charging (at 25W with the latest models). The puck is thin and sticks to the center of the back of the phone.
Does it charg as efficiently as a wired power bank?
Not even close. Ifixit did some testing, daily MagSafe wireless charging uses 36% more energy than a wire (which includes idle power draw). It also means slower charging.
The one I’ve used on my Samsung isn’t as fast as a wired power bank, but I don’t need to wrangle the cables like I do with the wired ones. I wouldn’t use a magsafe power bank to charge my phone from 0 (too slow). But leaving it attached gives me an extra couple of hours with just a little extra weight. Useful for things like conventions or travel.
That’s not physically possible.
But it is extremely efficient for what it is. The first number I found on google said it’s 95% efficient.
That doesn’t sound correct, considering the amount of wireless chargers that will take 10W, but can only deliver half that to the phone.
I’m also old, but I understand people do watch portrait videos. Sometimes a lot of them, in a single sitting. There’s a popular social media app which exclusively has short-form portrait videos.
I’m old enough that it would probably be creepy if I did use tik tok
My port isn’t worn out, but I’m worried it will become that way. I also don’t need it to charge at full speed overnight. Therefore, wireless charger.
They’re very convient, I use them for the phones, airpods, battery phone cases (airpods cases even with a silicon skin still on much less). Just nice to be able to leave your device on them while running them and know they won’t die out
So you just don’t like plugging the cable in?
Also charge battery phone cases that are much easier to slip on the wireless charger than plug with micro usb
When my mom finally ditched her land line and ported the number to a smart phone, getting a wireless charger that propped the phone up was a nice way to set up a sort of designated place to keep the phone (where the landline phone had been) so that there’s less chance she misplaces the phone or forgets to charge it.
You can also keep a wired charger in the same place but it charges faster
Bonus: the landline was already wired so just don’t unplug it ever and use it like before.
We did have wireless handsets back in the day…
Unplug the phone
I didn’t feel like typing that part.
And they had little docks to charge them (and transmit) but they also make docks for your phone.
If charging speed were your top priority, sure. She doesn’t use her phone hardly at all so the battery rarely gets depleted much, therefore how quickly it charges isn’t really that important. Not having to mess with a wire makes it more convenient to grab and go when she does need it, and more convenient to put it back when done. And no risk of damaging the USB port.
I’m still confused about this “hassle” people have with a wire, like you just plug it in. I used a 2016 iphone se for 5 years, still use it now for an bedside alarm and have never had any issues with the port. I’ve used a samsung for the past 4 years and never had an issue with the port, now that I think of it, in the 20 years I’ve used cell phones I’ve never had any issues with any phone ports. I’m sure there are some that get damaged but it seems to be so unlikely that I don’t see the need to spend extra money on a pad
It is a hassle, even if very very slight. One you need to plug in something small. The other you just drop a big thing onto a slightly smaller big thing.
Arthritis, poor eyesight, poor lighting, temporary/permanent hand disability are some that I can think of that greatly benefits wireless charging and found plugging in a cable a hassle.
Fair enough, I didn’t mean to he ableist
I use wireless charging 99% of the time. It’s convenient to plop your phone or earbuds down and effortlessly grab them when it’s time to go.
The other reason I like wireless: less wear on your phone’s USB port. Even though USB-C is supposedly good for millions of plug/unplug cycles I’ve had several phones with USB-C that get wonky after about 2+ years. “Wonky” as in having to hold the cable just right to transfer data or even successfully fast charge.
Wireless charging drastically cuts down on the amount of times you’ll be ramming a USB cable into it’s port, hopefully prolonging it’s useful life.
Follow up: does it work well with cases?
Wireless charging is unaffected by normal plastic or silicone cases (unless it’s super thick, like an OtterBox). Metal cases don’t work.
You do realize that wireless charging is also very inefficent and reduces your battery lifespan, right? It’s also kinda weird that your port goes bad after such a short time. Maybe you should clean it more often and make sure not to put any tension on it when you use it. I even have a 10 year old phone and the port (micro usb) still works perfectly fine.
I’ve been wireless charging exclusively for 5 years and had minimal change in battery life.
I’d be interested to see how you measure that. It’s also not really a matter of opinion. Even though you may not notice a wild difference, your battery did degrade more than it would’ve, if you’d used a wired charger.
Also, the inefficiency is bad enough for me to rule it out. You literally waste at least twice as much power compared to a wired charger (source). Although we’re not talking about a crazy amount of power, it’s pretty selfish to waste it just because you don’t want to plug in a charger.
I’ve had the phone for 6 1/2 years. It has a small 3000 mha battery. Initial reviews had it at 8 1/2 hours battery life at release. When I posted that I had been using the phone for 2 hours and was at 72% so extrapolated that 7 3/4 battery life. So less than a 10% drop. Granted I’m not a heavy phone user so I probably put less wear on my battery in general.
Yes use it for convince, but I’ve also had to replace phones for broken USB ports which in the grand scale is probably more wasteful than the extra power use.
It is more inefficiënt, yes. But why would it reduce battery lifespan? Is it because of the added heat from the wireless charging coils? My battery probably stays cooler with wireless charging then using the wired turbo charger. Which is more and more standard these days.
All our modern charging methods are really bad for batteries. Wireless is inductive which means the charging voltage is noisy and very variable, this means heat and that stresses the batteries faster. But, wired charging with PD uses really high voltages, which are sometimes way too fast. Also stressing the battery. We’ll see what comes of it but the recent couple of phone generations are prone to be the ones with the worse battery life expectancy.
Companies are usually aiming for 80% at two years time. That means that a phone that barely survives a day when new, will not make it through the day two years after. As the battery loses capacity, it requires more charges per day, accelerating the degradation.
Here’s iFixit assessment of wireless charging.
This is MKHB on why heat hurts batteries and how companies try to fight back the damage of fast charging.
Yeah, the USB port on all my phones was the first thing to go, and then you’re just stuck doing the stupid little dance of getting the cable to go in at the exact right angle to get it to charge. With wireless (especially with MagSafe), you just put it on the charger and you never need to worry about cables. I’ve got a plug on my USB port to keep dirt out now.
Wow, I’ve never had any issues with USB ports on any of my phones. Which one of us is the outlier? Do you ram the cable in too hard? Do you bend the connector in weird ways?
Nah, it’s just lint and other crap getting into the port. You can clean the USB-C ones easier than the micro-USB ones, but eventually they all go.
That wonkiness often times is just lint jammed into the charging port, and a thorough cleaning fixes the issue
It’s heartening to see someone else sharing what’s usually my line! I recommend a wooden toothpick for the aforementioned cleaning.
Ditto. The plastics floss/pick combos work even better. Being thinner and super flexible, they are less likely to cause damage and reach the tiny crevices better.
Adding on to this, it’s good to switch to wireless before the point gets wonky if you want to use the cable for data.
So I can keep the waterproof case sealed.

Does the thickness of the case increase the heat byproduct of wireless charging?
it shouldn’t.
There shouldn’t be any heat at all from the signal passing through the plastic (It’s basically transparent to RF’s,). The heat mostly comes from the RF interacting with the metal in the receiving antenna and inducing an electric current.
The extra space isn’t going to cause more heat on its own, but the phone is still going to get warm, and a thick case can prevent that heat from dissipating properly. A good charging design will already have taken this into account, and start limiting current if the temp gets too high.
The primary downside to using induction charging through a case is decreased power transfer efficiency due to the greater distance.
The case may prevent the heat from the phone (which should be the same) from dissipating so it can possibly build.
If someone claims to care about the climate, then using wireless charging makes them kind of a hypocrite. I asked ChatGPT to do some back-of-the-envelope math - so take these numbers with a grain of salt - but if everyone in the world switched to wireless charging, it would increase global energy consumption by around 12 TWh per year. That’s roughly equivalent to the total power usage of a small country like Iceland.
If someone claims to care about the climate, then using ChatGPT makes them an incredible hypocrite.
Kindly fuck all the way off
Huh, I never considered the inefficiency to be that bad
Some phones can get hotter (which is bad for battery health) when charging wirelessly.
The cold is also bad for batteries, so if you’ve been out in the winter for a while, it’ll help warm your phone up.
Don’t want to bother with a cable at night.
Mine’s magnetic. I have a charger on my nightstand. It keeps my phone in place, so it doesn’t get knocked down where it’s hard to get.
I also have a charging cradle on my desk. Keeps it upright. Makes it easy to glance at any notifications or quickly deal with MFA. I do sometimes unplug the cradle and just use it as a non-charging prop.
It’s also nice because, being magnetic, it also helps when I am having issues with my hands. (Stiff joints.)
I bought a little $15 phone stand from Amazon that does this great only without the charging stuff. It does have a slot on the bottom so you can plug the phone in while it’s on it tho.
When I sleep at my mom’s house, there’s a smart lamp my brother put in the spare room that has 1 USB port on it and a wireless charging pad. I opt to use the wireless charging pad at night for my phone and the USB for my watch. Makes it so I can charge two devices simultaneously without having to switch out USBs.
in a car, having wireless charging pad is nice for the convenience of taking it with you and putting it on very quickly and easily, especially if you’re actively driving and just want to do it with the least amount of distractions. Even with USB type C being reversible, you still need to make sure the cable gets in the hole and that’s dangerous to do while driving. But with a wireless pad, you don’t have to look and the magnet helps guide it on correctly for you. You still shouldn’t do this while driving, but out of the two, a vastly safer alternative. Besides that, it’s nicer to be able to just grab your phone and go when leaving the car and also easier when entering. Another addition is that a wireless charging pad takes the place of two accessories and combines them together. So you now have a mount and a charger in one instead of both being separate.
Hygienically speaking, it’s cleaner in that you don’t have to touch the charger. Best for public use like a coffee cafe. People are gross and I try my hardest not to have touch contact with stuff if I can help it. So to be able to drop my phone down without touching a cable a million other people have been touching helps with that too.
Even though I like it…I still want a port. A lot of cases don’t allow you to make direct contact to have wireless charging, so it’s not always an option. Also don’t always want to have my phone laying down, sometimes I want to use it while it’s charging, especially when typing, and that’s near impossible with 90% of charging pads unless it’s a special type of MagSafe for iPhones. Then there’s also the fact that I like it as an option in case something breaks. If the port is dirty or damaged, I still have the wireless charging option. Same in reverse if the wireless function ceases to work for some reason.
It’s also safer, because you’re not connecting something that might carry data to the USB port. Wireless charging cannot transmit data. USB can, so delivering a virus or something that way isn’t out of the question, where it would be harder to do that over wireless charging.
I think the public use one is the most legitimate reason I’ve read so far, I would definitely prefer a wireless charger if it were public but I’ve also never used any sort of public charger before
