Battery & Charging: Anyone really innovating?

Every time my cell-phone goes dead or my battery shows red signal, i wonder why there is absolutely no improvement in the battery life in past decade?

We have gone from b/w screens to color screens and not touch screens. We have improved from basic call / text messages to real time internet access... but where is the battery support for all these features.

We all saw what happened to iPhone 3G as compared to old iPhone... the battery life sucks.

The story is not too different with Laptops.. most of them give 3 hours backup time when they are "brand new" but as you start doing some serious work on it, within months the life comes down to 1 hour or even less. (Seriously, i have some friends who cannot use the laptop if the power is not supplied continuously... which defeats the purpose of having a laptop in the first place)

  • So my question is, why are there no new advancements in the battery technology?
  • why does it still take 2-3 hours to charge the battery? If the storage space can go from 1mb to 20gb in 5 years, why does the battery talk time go from 1 hour to 20 hours?
  • Are our researchers too concentrated in solving the storage problems and ignoring the energy problem?
  • We talk about Global Warming 1000 times a day, then is it rocket science that if we can change the charging technology and make our devices use less power for more time, it will save our earth (i know i am stretching the too far, but i really mean it!!
Any comments welcome!! Am i missing some thing REALLY BASIC here?
