"A mobile phone industry group Tuesday said 17 wireless operators and handset makers have agreed to standardize chargers by 2012 for most cellphones shipped."
Hallelujieh! This has bugged me for a long time. I have a box full of old chargers in the basement that are good for nothing! They perform such a simple function that it's hard to believe they're not standardized yet. Typically the electronics industry has been ahead of the curve on standardization. It's good to see that they're finally bringing chargers into the fold!
They'll use a micro-USB standard and will be up to 50% more energy efficient than current chargers (which, among other things, draw power whether the phone is charged or not)
