"But its only apple who now seems to have such serious problems with 'standard' battery degradation over time , that they have to choose for the 'drastic' solution of reducing frequency."
I have actually, personally, experience spontaneous reboots on my Samsung phone. In most cases, it's an unacknowledged problem. In my case, though, it's a Note 4, meaning all I had to do to solve the problem was change out the obviously-knackered battery (it was showing the first signs of bulging) for a new one.
