Then we will charge our cell phones on gas-stations.

Of course most, if not all users would rather chill with an empty battery than be caught using that nerdy/geeky stuff.
kinetic charger builtin into the battery itself or the phone would be helpful, but i don't think it would produce energy fast enough to suffice by itself, would increase battery life but not make wall chargers obsolete just yet. i'm not sure what output you can expect form solar cells nowadays though, my guess is it's probably still less than the wall for anything that you can easilly carry with you

Actually the problem is not battery life but heat management. If you have hardware with mobile phone form factor and consume energy so much that you drain your battery empty in a couple of hours, you start to have bad problems with heat. This means that you actually have to think power consumption issues when designing new processors for mobile gadgets and better power sources are not the solution for power consumption issues. Sure, with a bigger battery you can have your device run longer but you still need to limit the power consumption because of the heat.

or make the pathways more efficient so less heat is wasted
Hey! How about adding somthing like a stirling engine to convert the heat back into electricity?

Now all we need is some human-matrix-based energy batteries.

Iirc, there was also recent news about A9 reaching 2-2.5Ghz via 28nm production process.
As for batteries, as usual that will depend on the usage amount. A phone that is mostly on standby within a single cell will maintain battery longer then one that is in active use while traveling between multiple cells. And even then the A15 is designed to power up only those bits of the core that is actually needed, and can do so without impacting the performance. So if all it is doing is integer math, the FPU and related will stay powered down.
And all this in addition to the power saving extras like DSP that means the cpu will not be powered up at all when playing music or perhaps even video (at least on devices using SoC that is smart enough to provide a reprogrammable DSP rather then one with fixed codecs only).

How about wifi charging?
How's that coming along?
How's that coming along?
There are piss powered batteries though
