There's a free battery replacement program for the models affected [1].
My phone was one of the affected, but never got around to take it to repair shop because I thought the few random shutdowns were the only problem.

If this is true that apple throttle its performance due to battery Cycle, I will pissed too. Apple should have noted to me within iPhone that i should get a Battery replacement in the Apple Store, or I will be bringing my own Battery Pack when I am out.
Out of the bulk load of Energy Usage, CPU is not even the primary area where energy are used.
40%+ is the Display 20%+ are the Network Connection, WiFi or LTE. 10%+ are RAM, NAND, etc.
I am guessing around 20% is the CPU and GPU. So they lower this and try to save 10% more battery in response to lower battery cycle?
And they have an Financial interest to slow your phone. This makes me sick.
And I consider myself an Apple Fan.
My geekbench single-core score is 1045, vs expected 2500
