Wireless charging inefficiencies

[bradly1101]

This has always been my concern about wireless charging. It's been obvious since day one by reading the power requirements of wireless vs. wired chargers. Is the convenience worth it?

my asus zenfone 2 has quickCharge v2. from dead to almost 80% charged in 1hr. maybe 100% in 1.5 hrs, but im not that patient to wait.
so yeah, i rather take fast over wireless charging any time!

That's a dumb counter. It's not about one or the other.

I use a pad at night. I just place it there, and my phone's charging. It's always going to be easier than plugging a cable in.

QC is great for on the go. Wireless is stupidly convenient at work, at night, basically any time you know you won't be moving your phone around a lot. It's not a question of one or the other, as you can usually have both at the same time.

So just ask yourself if an extra dollar a year is worth the convenience or not.

The numbers we're talking about here are so tiny the efficiency discussion is utterly pointless. It costs like $1 to charge a modern cell phone daily for a year. So maybe you spend $2-3 doing it wirelessly. You would never, ever notice that on a power bill.

Multiply that by all the devices and you can see that it would make a difference. It's not always about the individual.

How worried you must be about all those people using the Snapdragon 810

I'm not worried about my electric bill, wireless charging just isn't for everyone. Unless it comes with my device I'll probably never have it, I can usually reach over and plug my phone in, it's not that difficult. Plus I have enough USB cables at work, in my car, etc.

I also don't want one sitting on my desk, I have enough junk. I also sometimes use my phone with the cable plugged in, I can't see holding a wireless charger up to my ear.

But if it works for you more power to you, I don't see it as a big necessity right now.

So why are you asking? That mentality means you had made up your mind already.

This thread got worthless fast.

How many devices do you have?
Gang... lets setup a gofundme fundraiser to help this guy pay his wireless charging hydro bill.

Love the convenience at work. The phone comes on/off the pad all day and needs constant charge as I use wifi tethering plus calling 9 hours a day.

You must hate electric toothbrushes and other common items that use wireless charging.

Like others have said, the energy lost is trivial. Your TV/Xbox/STB in standby consume more power in a day, much less any large appliance.

Worrying about this is like sweating that a window is open on the Titanic.

As a parent of a baby, wireless charging has been an unexpected plus. Beyond not having to fiddle around with a cable initially, I can grab my phone the couple times a night the baby gets up and just drop it back down in the pitch dark afterwards.

No its not a deal breaker, but there are a lot of smartphone features will less utility to me.

I love wireless charging! It seems like the USB port always eventually loosens / breaks / wears out somehow so wireless reduces the frequency of plugging and un-plugging the charging / data cable. It also prevents breaking the usb cable connector when accidentally knocking the phone off the night stand in the morning snoozing / turning off the alarm... I've broken far too many usb cables in this fashion...

Wireless charging is neat, but for me it's just not that big of a deal yet. The lack of wireless charging did nothing to prevent me from ordering a Nexus 6P.

When fast wireless charging becomes the norm and the chargers are cheap to buy, then I'll probably jump aboard.

Fast wireless chargers are down to $35 - I imagine by next summer they'll be more like $25.

In the UK, you can get the Samsung one for about $25, taxes and delivery included.

Annnnd, I looked at the article.

It's about a startup using lasers as a wireless power transmission source, and they are wildly inefficient! (Like 65% energy waste.)

Obviously, so are the current inductive chargers!

Wireless charging in concept is awesome - it's still lacking a company to really think it through on the implementation.

What is wrong with the implementation?

 

[MarkizSchnitzel]

I really hope that company Wiitricity ithink they are called, finally introduces TRUE wireless eletricity.

QI is just a stepping stone.

Small charge targets mainly. Ideally I would like a mat of whatever size you want and just toss it on there and it charges. Think you could have a night stand with the charging pad laid under veneer that took up the entire top surface or something.

I present to you the QE-TM101.
