Every single person that owns such a smart phone will need an iphone USB cable. Contrary to popular belief, this is necessary besides the regular dock station that you use. Most stations are only usable for charging the batter of the iphone and you will want to have a device that allows you to connect the phone to a USB plug. A universal dock that also includes a cable connect option is great but there are not many on the market. Most people will end up using USB cables. The problem is that there are too many options to not feel a little overwhelmed. ^

I am wondering how much efficiency could be gained by rewriting software to be energy efficient,

(I also do not like the idea of wireless charging due to the energy loss.)

You’ll take around 10Wh to charge a 5.5Wh phone battery. That’s 20-30% of an Ultrabook battery. Is it worth it?

You should never use wifi then Chippy, data loss chance is bigger than cable internet, thus more “inefficient”.

Wireless charging technology must be developed further until the efficiency can be so minimum. People should start using it whenever it’s available.

Producing cables is the same inefficient process because although every laptop has USB ports, every phone maker has their own port standard, so there must be a cable for each brand. Imagine if we don’t have to produce those cables, it’s much saving.

Pardon my english.

I don’t see an huge impact of power usage on this for current Ultrabooks anyway. Even if you charge your phone from near zero to full, you are talking about only 5W.

I’d like to see the new USB spec implemented where it can provide up to 100 W of power. It’d be great to only have one power adapter that can charge my notebook, phone, batteries, etc or USB ports, when the notebook is on AC power, that can provide as much current my peripheral devices require.

Too bad wireless charging has the “cool” factor that a lot of people seem to care about. Then again, we are talking about ultrabooks…

Thanks for the write up.

I started wondering about the energy loss when I first heard about wireless charging. Ultrabook ties it in well as a logical usage scenario, but it is a pity to see the chain of inefficient processes that go to charge the wireless device…
