Me too. If there is a way to get the technology at par with other improvements in other areas, it'd make sense to have a battery that lasts for at least a week on single charge on our mobile devices.

It is especially important for electric cars. Concerning the phones, there were improvements. But the phones at the same time requires more power.

The more the functions, the more power hungry the phone becomes. You can imagine the difference between the first generation phone that can only make calls and text, compared to now a phone is virtually a mini PC capable of running a lot of functions.

Believe me, I cannot run what I do on a phone... I need hundreds of CPUs ;)

It's understandable when running a simulation/program which requires some special software and more resources due to the amount of computational power involved.

Exactly! :)
