Anyone who uses a mobile device of any kind knows what a pita it is to carry around a charger to get the device through the day. Are we getting closer to really cutting the cord? Perhaps.

I can already leave my iPad charger at home. A reality that will continue even with the release of a power hungry 3rd generation device with the most amazing display ever manufactured for public consumption.

My phone isn't quite to that level yet. I keep a charger at work and have another in the car for topping off my phone when it's not in use. Most days I probably don't need it, but it's so vital I can't take a chance. I'd welcome the opportunity to not even think about topping off.

My laptop is the real week point in my device lineup. There's no way to get through an entire work day using it without it's power supply. But with the increasing adoption of SSD drives and better battery technology revealed by this ZDNet story, even this problem looks like it could be solved rather soon.

All this points to something very significant. It suggests that Apple has managed to increase significantly the power density of the Li-ion cells that it uses. In an industry that has seemed stagnant for some time now, this is quite an achievement and goes to show that Apple’s battery research labs and manufacturing plants have been hard at work. There’s no doubt that we’re going to be seeing the fruits of this labor in other Apple products soon.
