And we can see the problem all of those from quite a distance.

It has about 50% loss of power but as phones are low powered device people won't mind. That's probably why it came to the toothbrush.

Am sure many people are already used to using one USB adapter for a multitude of devices.

The Apple cradle system works too. Competition amongst other manufacturers has meant the USB socket is never in the same place.

where do you get this 50% loss of power from? it's actually a lot more efficient than that. all transformers basically work on the same principal. i have done a cost calculation earlier in the thread.

Qi has been adopted by HTC, Huawei, LG Electronics, Motorola Mobility, Nokia, Samsung, and Sony. it's only apple that can balls it up.

A screen that is useable in bright sunlight and a decent battery life would be a start.

I'm sure manufacturers claim up to 70% efficiency so add convenience of distance and all that I think 50% is a fair estimate.

There is an electric charging system for cars that involves driving over an induction mat that is 82% efficient. And that is really only the beginning. There's a whole load of physics that enables accurate calculation. You can go higher at higher frequencies.

What makes you think efficiency drops with distance?

colour e-ink should be available soon which will both improve sunlight readability and reduce power usage. I think there are currently limitations in resolution and don't know what brightness will be like.

You get energy from your local TV transmitter.

The 50% to 70% if for actual contact. True wireless gets a mention in the link but surely things drops off further.

"Intel and WiTricity are trying to use magnetic induction to charge devices over the air. It’s pretty sweet, but so far efficiency is governed by how large the magnetic coils are and by how far apart they are from the device that needs power. The demos are using really big magnets or ones close together, and aren’t offering a lot of charging efficiency."

There is no such things as a free lunch.

it doesn't quite work like that. or i don't think it does.

the load on the driving coil is caused by the current/magnetic field induced in the receiving coil.

The Kyobo Mirasol one launched in Korea nearly 12 months ago. It runs Android and has a 5.7" 1024x768 colour display.

I have heard little since maybe low yields are the problem.
Its mega battery life is certainly appealing.

Cleared at $87 each so failed?
What about GPS devices etc or too expensive to produce?

"Now, Qualcomm did show off a new 4.3″ screen at SID Display Week last month". They are still trying then.

Not for me thank you very much. you have Google sending adverts direct to your optic nerve.


i don't like the idea of NFC, so this optic nerve idea is certain a no no.

It took me long enough to go for a smart phone to start with, still considering going back to a normal phone once contract have run out.

something else I am a bit worried about, how safe would it really be?

i will stick with a cable.

Because of cleverness it's basically off when it's not charging something.

But when it is charging something if you go anywhere near it it will shrink your balls.

believe me, the next generation already think very differently to you,

You aren't obliged to use the smartphone till contract runs out.

Sell the smartphone and get yourself a normal phone if you hate it that much.

Maybe so, which to be honest is the scary part, they are willing to sell their privacy to faceless companies.

the phone that i had with my contract went belly up a few weeks back, I got another phone, cheap android phone to replace it, for the next six months.

It is not that I hate smart phones, it just sometimes I think they can be a distraction and maybe send to much info to people who i would prefer not to know that info.

A normal mobile phone, while it can be tracked via the network it don't send info back to Google.

i will probably stay with what I got and go onto sim only as emails and also having a look at facebook without the computer can be useful.
but sometimes I have to admit I wish I did not have this quest for trying things

they are willing to embrace technology, not they are willing to lose control. two completely different things.

I think you have a basic mis-understand about smart phones based on this and other comments you have made. Android does NOT send back information unless you choose to let it or use select to use apps that do.

Smart phones, same as PC do allow you control your own information, how, where, who you wish to share that information is up to you.

But they are losing control, they will use any thing if they think it is cool and the in thing.

And you know this how?

Only if you know how to control it and a Pc you have to use software to stop the information from going back, certainly with google adverts on almost every site.


I have always said I don't mind adverts, but there is no need for the tracking.

I read somewhere that the new Kindle Paperwhite reader introduced this week has a front-lit screen which apparently works well under sunlight.

You think people buy smartphones because they are the in thing?

Not because they have a multitude of features that people find useful in their pocket then?

You are paranoid, this fear of Google tracking you is not healthy chap, you need to chill out, maybe go and talk to someone about this irrational fear mate

Sometimes they do, certainly the younger people. most smart phones now got the same features and yet when something new comes out youngsters get it.

I knew someone who had a new mobile every six months, I doubt many are that bad, but people seems to change their mobiles a lot.

You keep telling me to chill out, I am fine. google do track, you should no that. so it is not paranoia
