I don't think that Power or Endless make much difference here.
There are more important factors.
I use batteries with a large capacity whenever possible and operate almost all devices that actually need batteries with them.
It should be noted that rechargeable batteries only deliver a voltage of approx. 1.2 volts, whereas batteries deliver 1.5 volts.
This means that a rechargeable battery has to supply more current to generate the same power and therefore often lasts much less time than "real" batteries.
In addition, wireless phones often have charging stations, but these are not very intelligent - which means that the battery suffers in the long run.
